Can poor speeds let you leave broadband early without penalty? A practical 2026 UK guide

1. Ofcom's Voluntary Code of Practice on Broadband Speeds explained

Ofcom operates two parallel Voluntary Codes of Practice on Broadband Speeds: one for residential customers and one for business customers. The current Codes were most recently updated in September 2022 with changes in force from 21 December 2022 per Ofcom. Per Ofcom, the main purpose of the 2022 changes was to update the previous 2018 broadband speeds codes of practice so that the right to exit (which applies to broadband and other bundled services) is in line with Ofcom's revised General Conditions of Entitlement (revised GCs).

Per Ofcom, the Voluntary Code represents the voluntary commitment of ISPs to:

• Provide customers with transparent and realistic information on the speeds of their residential broadband services at the point of sale, including a personalised minimum guaranteed speed (the Guaranteed Minimum Speed or GMS).
• Help customers manage speed-related problems after buying, with clear processes for reporting, fault-finding, and remediation.
• Provide a right to exit without penalty if the customer's speed falls below the minimum guaranteed level and cannot be restored within 30 days.

Per Ofcom, the four key changes introduced under earlier 2018 revisions and carried through to the 2022 code include:

• Improved relevancy of speed estimates by reflecting peak time speeds (typically 8pm to 10pm).
• Providing a personalised minimum guaranteed download speed at the point of sale.
• Strengthening the right-to-exit by introducing a 30-day time limit by which signatories must resolve speed issues before allowing customers to exit their contract without penalty.
• Allowing the right-to-exit to apply not just to broadband but to bundled services (TV, landline) at the same time.

2. What is the Guaranteed Minimum Speed (GMS) and where to find yours

The Guaranteed Minimum Speed (GMS) is the personalised minimum download speed your provider commits to deliver to your specific address under the Voluntary Code. Per CompareFibre, the GMS is specific to your line and appears on your Key Facts document at sign-up; it is the figure your ISP is contractually responsible for delivering, not the headline "up to" advertised speed.

How the GMS works in practice:

• Calculated at sign-up. When you order a broadband package, the provider runs a line check at your address and calculates a minimum speed estimate based on your line characteristics (distance from cabinet for FTTC; line technology and routing for FTTP; cable network conditions for Virgin Media; XGS-PON characteristics for newer altnets). This minimum estimate becomes your contractual GMS.
• Always lower than the advertised "up to" speed. Per CompareFibre, a package advertised at 36 Mbps might have a minimum guarantee of 25 Mbps for your specific line. This is normal: the GMS reflects realistic minimum performance allowing for evening peak time congestion (typically 8pm to 10pm).
• Recorded on your Key Facts document. Per CompareFibre, providers must give you a personalised minimum guaranteed speed on the Key Facts document at the point of sale. This document is sent at sign-up (typically by email) and must be retained as evidence.
• Available through your account portal. Most major UK ISPs also display the GMS in your online account portal alongside the package details and contract terms.
• Distinct from "average" or "median" speeds. The GMS is the minimum the provider expects to deliver at peak times; the "average" or "median" speed shown in advertising represents typical performance across the customer base. Both must be disclosed under the Voluntary Code per Ofcom.

3. How to test and document your broadband speed properly

Before logging a formal complaint that triggers the 30-day fix window, build clear evidence that your line consistently performs below the GMS. Per CompareFibre, customers should test speed over two weeks and compare to the minimum guaranteed speed on the Key Facts sheet; if it is consistently below the guarantee, contact the provider to start the 30-day fix process. This section covers what good evidence looks like.

• Test using Ofcom-approved tools. Per Ofcom, the official Ofcom broadband speed checker is available at ofcom.org.uk and provides free residential testing. Other widely-used tools include speedtest.net (Ookla) and fast.com (Netflix); your provider may also have its own approved checker. Per CompareFibre, you can test using Ofcom's broadband speed checker or your provider's own tool.
• Always test on a wired Ethernet connection where possible. Per the BBS guide on broadband speed measurement, connect your laptop or test device directly to the router via Ethernet cable and disable Wi-Fi during the test. This isolates the line speed from Wi-Fi performance variability. The GMS applies to wired performance; Wi-Fi-related shortfalls do not qualify.
• Test multiple times across multiple days. Per CompareFibre, run tests 5-10 times over a week using a wired connection. Test at different times of day including the 8pm to 10pm peak window, since the GMS reflects expected peak time performance.
• Record all results with dates and times. Per fightingback.uk, record all test results with dates and times for evidence; average the results and compare to the guaranteed minimum.
• Look for consistent shortfall, not occasional dips. Per Ofcom, the right-to-exit applies where speeds consistently fall below the GMS, not where occasional dips occur. A pattern of below-GMS results across multiple tests at multiple times establishes the consistent shortfall the Voluntary Code addresses.
• Restart the router and re-test before contacting the provider. Some shortfalls are caused by router firmware issues that resolve with a restart; performing this basic step before logging the complaint demonstrates reasonable diagnostic action.

4. The 30-day fix window and what your provider should do

Once you have logged a formal complaint about consistent speed shortfall, the Voluntary Code gives your provider 30 days to investigate and remediate the problem. Per Ofcom, this 30-day time limit was introduced under the 2018 revisions and carried through to the 2022 code; signatories must resolve speed issues before allowing customers to exit their contract without penalty. This section covers what the 30-day window typically involves.

• Initial diagnostic phase. Most providers run remote line tests as the first step, checking for line errors, signal-to-noise ratio issues, sync speed at the cabinet (for FTTC), or fibre signal strength (for FTTP and altnet networks).
• Engineer visit if needed. Where remote diagnostics don't resolve the issue, the provider typically arranges an engineer visit. For Openreach-based ISPs (BT, Sky, Vodafone, TalkTalk, EE, Plusnet, NOW Broadband, Zen Internet), Openreach engineers attend; for Virgin Media on cable, Virgin Media engineers attend; for altnets, the network operator's engineers attend.
• Common remediation actions. Replacement of the master socket; replacement of the modem or router; cabinet-level fixes for FTTC; cable repair for damaged drop wires; ONT (Optical Network Terminal) replacement for FTTP; signal level adjustments for cable. Where the issue is upstream (in the wider network), the network operator may need to investigate exchange or cabinet equipment.
• Ongoing monitoring. After remediation, the provider typically continues to monitor the line for a period to confirm the fix is durable. You may be asked to run further tests during this monitoring period.
• Communication during the window. Per Ofcom's General Condition C4, providers must keep customers informed of progress with reasonable frequency during the 30-day window.
• If the fix succeeds. If speeds are restored to or above the GMS within 30 days, the right-to-exit does not apply. However, you may still be entitled to compensation under the Automatic Compensation scheme if the original loss of service met that scheme's criteria (typically 2+ working days of total service loss).
• If the fix fails. Per Ofcom, if the provider cannot restore speeds to or above the GMS within 30 days, the customer has the right to exit without penalty. Per CompareFibre, the customer can leave their contract penalty-free under the Broadband Speeds Code in this circumstance.

5. The right-to-exit process step-by-step

Once the 30-day fix window has passed without the GMS being restored, the right-to-exit becomes available. This section walks through the formal process per Ofcom's Voluntary Code and the typical UK ISP customer service experience.

1. Confirm in writing that the 30-day fix window has ended. Reference the date you first logged the formal complaint. Reference the GMS, the average measured speed during testing, and the documented outcomes of any engineer visits or remediation attempts. Request acknowledgement that the right-to-exit now applies.
2. Request the right-to-exit formally. State that you are exercising your right to exit without penalty under Ofcom's Voluntary Code of Practice on Broadband Speeds (residential code in force from 21 December 2022 per Ofcom). Request confirmation in writing of the exit terms including effective date, equipment return process, and final billing.
3. Specify which services you wish to exit. Per Ofcom, the 2022 code update aligned the right-to-exit with bundled services; this means TV, landline, and mobile services bundled with the broadband can typically also be exited under the same right. Be explicit about which services you wish to terminate.
4. Confirm equipment return arrangements. Most providers send a prepaid return bag for the router, set-top box, and any other equipment. Some require return within 14 days; others within 28 days. Verify the deadline and the postage method (typically Royal Mail tracked or courier).
5. Confirm final billing and refund. Verify that no early termination charges will apply (this is the substance of the right-to-exit). Verify whether any pro-rata refund is due for any unused service period or paid-ahead amounts. Verify the date of final bill and the date of service cessation.
6. Plan continuity. Decide whether to switch to a new provider before the existing service ceases (using One Touch Switch where possible to minimise downtime) or after. If the existing line is consistently below GMS, you'll likely want to start the new service ASAP.
7. Keep all written confirmation. The right-to-exit confirmation, equipment return tracking number, and final bill should all be retained for at least 12 months in case any disputed charges arise later.

6. Exceptions and edge cases (Wi-Fi, wiring, devices)

The right-to-exit applies only where the speed shortfall is the responsibility of the provider's network. Per Ofcom, a number of common scenarios fall outside the right-to-exit and need to be ruled out before formally invoking it.

• Wi-Fi performance is excluded. The GMS applies to wired Ethernet performance at the master socket or router output, not to Wi-Fi speed in any room of the house. Wi-Fi performance depends on home layout, walls and floors, distance from the router, interference from other devices, the age of the router, and the Wi-Fi capability of the connecting device. Per the BBS guide on broadband Wi-Fi versus line speed, low Wi-Fi-only speeds with full GMS-compliant wired speeds do not qualify for right-to-exit.
• Old or under-spec home wiring. Issues caused by aged internal phone wiring (relevant for FTTC), poor-quality Ethernet cabling, or worn connectors inside the home are typically the customer's responsibility unless the provider's installation work caused the problem. Per the BBS guide on broadband speed factors, home wiring problems can mask underlying line performance.
• Old or under-spec connected devices. An old laptop with a 100 Mbps Ethernet port can never measure above 95 Mbps regardless of line speed. Older smartphones may struggle to demonstrate gigabit-class speeds. The test device must be capable of measuring speeds at or above the GMS.
• Speeds quoted as best-efforts in remote rural areas. Where a provider has explicitly noted at sign-up that the line is in a marginal coverage area and the GMS reflects this, exceeding the GMS may not be straightforward. However, the GMS still represents the contractual floor: if speeds fall below it consistently, the right-to-exit still applies.
• Issues caused by external factors. Damaged cables caused by third-party works (utility companies, neighbours' building work) may take longer than 30 days to resolve. In these cases the provider may seek customer agreement to extend the window; the customer is not obliged to agree, and after 30 days the right-to-exit applies.
• Loss of total service rather than slow speeds. Where the line is completely down rather than just slow, the situation is governed by the Automatic Compensation scheme rather than the Voluntary Code on Broadband Speeds. Per Ofcom, automatic compensation pays for delayed repairs (typically £10.74 per day for total loss of service for two-or-more working days under the April 2026 rate update), missed engineer appointments, and delays with the start of a new service.
• Cooling-off period as a separate right. In the first 14 days of a new contract you have a separate right of cancellation under UK consumer regulation for distance contracts, regardless of speed performance. This is a no-fault right that doesn't require the 30-day fix window. Per CompareFibre, providers cannot charge exit fees during the cooling-off period.

7. Which UK ISPs are signed up to the Voluntary Code

Per Ofcom, the current signatories to the Voluntary Code of Practice on Broadband Speeds (Residential, in force from 21 December 2022) cover the substantial majority of UK residential broadband customers. This section lists the major signatories with notes on each provider's specific approach.

Beyond the named signatories, most major UK altnets follow equivalent practice even where not formally signed up to the Voluntary Code. CityFibre's wholesale platform is used by signatory ISPs (Vodafone, TalkTalk, Sky on CityFibre packages, Zen Internet) so the right-to-exit applies through those retail brands. Direct altnet retail brands (Hyperoptic, Community Fibre, Gigaclear, YouFibre, Toob, BeFibre, 4th Utility, Ogi, and others) typically provide a clear personalised speed estimate at sign-up plus a fault-finding and exit process; always check the provider's terms and conditions before signing.

8. Related UK consumer rights (cooling-off, automatic compensation, ADR)

The right-to-exit under the Voluntary Code on Broadband Speeds is one of several UK consumer protections relevant to broadband contracts. Each operates differently and applies in different scenarios; understanding which right applies in your situation prevents you from missing alternative routes to redress.

• 14-day cooling-off period. Per CompareFibre, customers have a 14-day cooling-off period after signing any new broadband contract during which they can cancel without penalty. This applies whether you sign up online, over the phone, or in store. This is a separate, no-fault right under UK consumer regulation (Consumer Contracts Regulations 2013) for distance contracts and applies regardless of speed performance. Per CompareFibre, providers cannot charge exit fees during the cooling-off period.
• Automatic Compensation scheme. Per Ofcom, broadband and home phone customers receive compensation from their service provider for delayed repairs, missed engineer appointments, and delays with the start of a new service. The April 2026 rate update set the daily rate at £10.74 per day for total loss of service after two working days, £30.49 per missed engineer appointment, and £6.10 per day for delayed start of a new service. This scheme runs separately from the Voluntary Code on Broadband Speeds.
• Telecoms Consumer Charter (introduced February 2026). Sector-wide Charter setting out minimum customer service standards across UK ISPs.
• Voluntary Code on Broadband Speeds (this page's main topic). Right-to-exit if the GMS cannot be restored within 30 days per Ofcom.
• End-of-contract notification. Per CompareFibre, providers must send an end-of-contract notification 10-40 days before the deal expires, clearly showing what the customer is currently paying and the best deals available. This is a notification right rather than an exit right but provides the trigger for considering switching.
• One Touch Switch. Per CompareFibre, the One Touch Switch process (launched 12 September 2024) lets customers change provider by contacting only the new provider; BT, Sky, Virgin Media, EE, TalkTalk, Vodafone and all major Openreach-based ISPs support this system. Over 1.6 million households used One Touch Switch in its first year per CompareFibre.
• Alternative Dispute Resolution (ADR). Per Consumer Voice, all UK broadband providers must be members of an ADR scheme (Communications Ombudsman or CISAS). After 8 weeks of unresolved complaint, customers can escalate to ADR for binding adjudication; ADR can force compensation and penalty-free exit per fightingback.uk.
• Ofcom complaints process. Per Ofcom, while Ofcom doesn't handle individual consumer disputes, it monitors complaint volumes and can take enforcement action against providers that breach General Conditions. Customers can file complaints at ofcom.org.uk for monitoring purposes alongside ADR escalation.
• Consumer Rights Act 2015. Underlying statutory protection; services must be "fit for purpose" and "of satisfactory quality". Provides an alternative legal route for redress where Voluntary Code signatory commitments don't apply.

9. Practical scenarios: Wiltshire renter, London household, Manchester family

This section walks through three typical UK 2026 scenarios to illustrate how the right-to-exit applies in practice.

Scenario 1: The Wiltshire renter on a 24-month FTTC contract

Sarah lives in a rented flat in Swindon (SN5 postcode) on a 24-month FTTC contract with a major UK ISP. Her Key Facts document shows a Guaranteed Minimum Speed of 35 Mbps download. Six months into the contract, she notices speeds have dropped: video calls struggle, Netflix buffers, and uploads to cloud storage are painfully slow.

• Step 1: Document. Sarah runs Ofcom-approved speed tests over 14 days using a wired Ethernet connection to her router. Average peak-time download speed: 18 Mbps, well below the 35 Mbps GMS.
• Step 2: Contact the provider. Sarah emails her ISP customer service in writing referencing her account number, the GMS, the testing methodology, and the average results. The ISP acknowledges the complaint and starts the 30-day fix window per Ofcom.
• Step 3: Engineer visit. Openreach engineer attends within 7 days, identifies a faulty join in the cabinet, and remediates. Speeds return to 38 Mbps average peak-time, above the GMS.
• Outcome. The fix succeeded within the 30-day window; Sarah is not entitled to exit but receives Automatic Compensation if the original delay had caused total service loss for 2+ working days. Sarah continues with the existing contract.
• If the fix had failed. If 30 days had passed without speeds returning to the GMS, Sarah could have exited the contract without penalty per Ofcom, then switched to an FTTP provider in her Swindon area (with Swindon's strong altnet competition including CityFibre's £40m investment per ISPreview, Vodafone Pro on CityFibre, toob 900 Mbps symmetric, and Fibrehop on CityFibre).

Scenario 2: The London household with a multi-network address

The Khan family lives in a London flat (E14 postcode) on a 12-month Virgin Media cable contract with a 264 Mbps GMS. Three months in, evening speeds drop to under 100 Mbps consistently, making 4K streaming and multi-user working from home difficult.

• Step 1: Document. Wired tests over two weeks show peak-time average of 75 Mbps, well below the 264 Mbps GMS.
• Step 2: Contact Virgin Media. The household contacts Virgin Media customer service in writing. Virgin Media starts the 30-day fix window.
• Step 3: Engineer visits. Two engineer visits over 21 days identify a node-level congestion issue affecting the local Virgin Media cable network. Virgin Media commits to upgrade the node but cannot complete this within the 30-day window.
• Outcome. Per Ofcom, after 30 days without restoration to the GMS, the Khan family exercises the right-to-exit. They switch to a London altnet (Community Fibre, with London-only operations and outright fastest UK download/upload speeds per Opensignal December 2025 in London) on a new 12-month contract. The cross-network switch via One Touch Switch is effectively zero-downtime.
• Bundled services. Per Ofcom's 2022 update, the right-to-exit applied to the bundled Virgin Media TV service alongside the broadband; the family terminates both under the same right.

Scenario 3: The Manchester family in a CityFibre area

The Patel family lives in a Manchester suburb (M19 postcode) on a 24-month Vodafone Pro contract on CityFibre with a 800 Mbps GMS. Five months in, speeds drop to around 200 Mbps consistently.

• Step 1: Document. Wired tests over two weeks show peak-time average of 220 Mbps, well below the 800 Mbps GMS.
• Step 2: Contact Vodafone. Vodafone is a Voluntary Code signatory per Ofcom. The family contacts Vodafone customer service in writing. Vodafone starts the 30-day fix window.
• Step 3: Diagnostic and remediation. Vodafone's technical team identifies an ONT (Optical Network Terminal) configuration issue. Within 14 days the configuration is corrected. Speeds return to 850 Mbps average peak-time, above the GMS.
• Outcome. The fix succeeded within the 30-day window; the family is not entitled to exit but the issue is resolved. Manchester's strong multi-network choice (with 67 percent altnet coverage per Switchity, plus CityFibre's wholesale, Openreach FTTP, and Virgin Media plus Nexfibre) means alternative options would have been straightforward had the right-to-exit applied.

10. After you exit: switching to a better provider

Once the right-to-exit has been confirmed, the practical next step is choosing a replacement provider. Speed shortfall on one network often reflects underlying issues with that specific connection rather than UK broadband generally; alternative networks at the same address frequently deliver materially better performance.

• Check what other networks reach your address. Most UK addresses in 2026 have multi-network choice through Openreach FTTP and FTTC, Virgin Media cable plus Nexfibre, plus altnets including CityFibre wholesale (supporting Vodafone Pro, Sky Gigafast, TalkTalk, Zen Internet, plus distinctive retail brands like Cuckoo and toob), Hyperoptic in MDU buildings, Community Fibre in London, Gigaclear in rural areas, plus regional altnets. See the BBS guide on comparing broadband by postcode for address-specific availability.
• Switch via One Touch Switch. Per CompareFibre, the One Touch Switch process (launched 12 September 2024) lets customers change provider by contacting only the new provider; the new provider notifies the old provider and coordinates the cessation. Most major UK ISPs support OTS including BT, Sky, Virgin Media, EE, TalkTalk, Vodafone, Plusnet, NOW Broadband, Three Broadband, plus most major altnets.
• Plan timing carefully. If you've exercised the right-to-exit you may want continuous service: place the new order before the old service ceases. Cross-network switches (Openreach to Virgin Media, Openreach to a CityFibre retail brand, etc.) typically have effectively zero downtime as the new line is provisioned in parallel. Same-network switches (BT to Sky, both on Openreach) typically have 1-2 hours of switch downtime.
• Choose the right speed tier. Light usage households are typically comfortable with 30-75 Mbps; standard households (multi-device, regular streaming, working from home) typically with 100-300 Mbps; heavy households benefit from 500+ Mbps; multi-gigabit only makes sense for content creation, multi-user working from home with heavy uploads, technology professionals. See the BBS speed and needs hub for detailed framework.
• Consider symmetric upload. If working from home with video calls, cloud syncing, content creation, live streaming, or hosting are important, choose an FTTP package with symmetric upload (most FTTP packages at 500+ Mbps tier offer symmetric). CityFibre retail brands at higher tiers (including Vodafone Pro II up to 2.2 Gbps), Hyperoptic at every tier, toob at 900 Mbps with the toobpromise, plus most XGS-PON altnets offer symmetric speeds. Virgin Media cable is asymmetric; Nexfibre XGS-PON at higher tiers is symmetric.
• Consider customer service quality. Where customer service quality is a primary consideration, Zen Internet's UK customer service satisfaction leadership with Which? 84 percent customer satisfaction and PC Pro 22-year award streak plus Contract Price Promise is a meaningful differentiator; Hyperoptic's top-five Ofcom customer satisfaction position with approximately 4 complaints per 100,000 customers; Hyperoptic's minimum speed guarantee at advertised speeds.

11. If your provider refuses: ADR and Ofcom escalation

The right-to-exit is straightforward in most cases: documented below-GMS performance plus 30-day failure to restore equals exit without penalty. Occasionally, however, a provider may dispute the evidence, dispute the methodology, or dispute the right itself. This section covers the formal escalation routes if that happens.

• Stage 1: Internal complaint. Per Ofcom's General Condition C4, providers must have a clear complaints process. Most major UK ISPs have multiple internal escalation tiers (frontline customer service, complaints team, executive complaints). Insist that the complaint is logged formally and that you receive a written reference number. Per Ofcom GC C4, providers must keep customers informed of progress.
• Stage 2: Deadlock or 8 weeks unresolved. Per Consumer Voice, all UK broadband providers must be members of an Alternative Dispute Resolution scheme (Communications Ombudsman or CISAS). After 8 weeks of unresolved complaint, or after the provider issues a "deadlock letter" (formal statement that the internal complaint cannot be resolved), customers can escalate to ADR. The deadlock letter is the trigger that opens ADR access without waiting the full 8 weeks.
• Stage 3: ADR submission. Per fightingback.uk, ADR can force compensation and penalty-free exit. Submit your case to the relevant ADR scheme (Communications Ombudsman or CISAS depending on which scheme your provider belongs to) with all documentation: GMS figure, speed test results, written complaint history, provider responses, deadlock letter (if issued). ADR is binding on the provider but not on the customer; if you accept the ADR decision, the provider must implement it.
• Stage 4: Ofcom complaint for monitoring purposes. Per Ofcom, while Ofcom doesn't handle individual disputes, it monitors complaint volumes and can take enforcement action against providers that breach General Conditions. File a complaint at ofcom.org.uk; this doesn't resolve the individual case but contributes to Ofcom's regulatory oversight.
• Stage 5: Small Claims Court (rare). Where ADR doesn't resolve the matter and substantial sums are at stake, the Small Claims Court (for claims up to £10,000 in England and Wales; up to £5,000 in Scotland; up to £3,000 in Northern Ireland) is the final route. This is rare for typical right-to-exit disputes.
• Throughout: keep meticulous records. Every email, every test result, every phone call summary, every written response should be preserved. Time-stamped speed test screenshots are particularly valuable. Where phone calls happen, follow up immediately with a written summary email asking for confirmation in writing.

12. Five questions to ask before exercising the right-to-exit

Before formally invoking the right-to-exit, work through these five questions to confirm the action is correct for your situation.

1. Have I confirmed my Guaranteed Minimum Speed (GMS)? Locate the Key Facts document or account portal entry showing the personalised GMS specific to your address. Without this figure you cannot prove a shortfall. If you can't locate it, request it from the provider in writing.
2. Is my evidence of below-GMS performance solid? Multiple wired Ethernet speed tests over multiple days using Ofcom-approved tools, including peak-time tests (8pm-10pm), with consistent below-GMS results. Documented in writing with dates, times, tools used, and results. See the BBS guide on broadband speed measurement for detailed framework.
3. Have I ruled out Wi-Fi, wiring, and device issues? Wired Ethernet tests (not Wi-Fi); modern test device capable of measuring at-or-above the GMS; no evidence of home wiring problems. If shortfalls only appear over Wi-Fi or with one specific device, the right-to-exit doesn't apply.
4. Is my provider a Voluntary Code signatory? Per Ofcom, current signatories include BT, EE, Plusnet, Sky, NOW Broadband, Vodafone, TalkTalk, Virgin Media, plus Zen Internet. If your provider isn't a signatory, alternative routes apply (Consumer Rights Act 2015, Ofcom General Conditions, ADR membership).
5. Have I given the provider a formal opportunity to fix the issue? The 30-day fix window is the substance of the Voluntary Code; the right-to-exit only applies after the window has passed without restoration. Contact the provider in writing referencing the GMS, the test methodology, and the average results; this triggers the 30-day window per Ofcom.
