Direct answer: For broadband for online and proctored exams in the UK, prioritise a stable connection over a headline speed. Full fibre is usually the strongest home option where available, but good Wi-Fi placement, a wired connection and avoiding a switch close to exam day matter just as much.
- Choose the connection type available at your exact address, not the fastest sounding advert.
- Check the full contract cost, any setup charge and stated in contract price rises before ordering.
- Avoid planned installation work or a broadband switch in the days immediately before an exam.
- Use a wired Ethernet connection where practical, or test your Wi-Fi in the room where you will sit the exam.

What broadband speed do I need for an online proctored exam?
A modest, consistent connection is more useful for a proctored exam than a very high maximum download speed that varies during the day. The exam platform normally needs enough capacity for video, audio, screen sharing and identity checks, whilst the household connection must also cope with anything else using the internet.
Check the exam provider's technical requirements first, because required upload speed can be as relevant as download speed. Then test the connection at the planned exam time, in the exact room you will use. A video call, cloud backup or large download from another person in the home can affect available capacity, particularly on an older FTTC line.
For a high stakes assessment, ask others in the property to pause non essential internet use. Connect the exam computer by Ethernet if possible. If Ethernet is not practical, keep it close to the main router and avoid relying on a Wi-Fi signal that has already proved unreliable.
Is full fibre better for online and proctored exams?
Yes, FTTP, also called full fibre, is generally the best fixed line choice for exam reliability where it is available at your address. It uses fibre to the premises rather than relying on the copper section used by FTTC, which can make it a more suitable option for homes that need dependable video calling and uploads.
Full fibre availability is not universal, so the address check is decisive. Full fibre was available to 78% of UK homes in September 2025, according to Ofcom's Connected Nations 2025 report. That national figure does not confirm what can be ordered at a particular property, especially in flats, new builds and locations served by different networks.
Cable and some altnets can also offer suitable fixed broadband, subject to address availability and the terms of the service. If fixed broadband is not ready in time, 4G or 5G home broadband can be a practical temporary option, but test it carefully indoors before trusting it for a supervised assessment.
How can I make Wi-Fi reliable for an online exam?
The most reliable improvement is to remove avoidable Wi-Fi uncertainty before the exam starts. A wired Ethernet connection from the router to the computer avoids interference from walls, distance and other wireless devices. It is a practical precaution, not a guarantee against every connection issue.
If you need Wi-Fi, work in the same room as the router where possible. Place the router in an open, central position rather than in a cupboard, behind a television or on the floor. Test the exam device after any router move, because a signal that looks strong may still vary during a video call.
Restarting the router immediately before an assessment is not always wise if the connection is already stable. Do your testing earlier, make any changes a few days in advance and retain a fallback plan. That might mean knowing where mobile coverage is strongest or arranging another suitable location, subject to the exam rules.
What broadband costs should I check before choosing a contract?
Compare the total commitment, not only the advertised monthly figure. Your order summary should show the monthly price, contract length, any setup or activation charge, delivery costs where applicable and the terms for leaving early. Prices, available speeds and installation options are current month and postcode variable, so use the final address level quote as the decision point.
For new contracts sold from 17 January 2025, providers must state any in contract price rises in pounds and pence at the point of sale. Ofcom's rule bans inflation linked mid contract rises in new consumer contracts, although a contract can still include the clearly stated pound and pence increase described at checkout (Ofcom, 2024).
An exam requirement can justify paying slightly more for an appropriate connection, but only if the total cost remains clear. A shorter contract may suit a tenant or someone moving soon, whilst a longer term can make sense if the service, installation date and total price are right for the household.
Can I switch broadband before a proctored exam?
Yes, but do not leave the timing to chance. A switch can involve an activation date, equipment delivery or an engineer visit, depending on the technology at your address. Keep your existing connection active until the new service is working, unless the order process specifically explains otherwise and the timing is safe for your circumstances.
One Touch Switch went live on 12 September 2024. Under this process, the customer contacts only the new provider, which manages the switch with the old provider through TOTSCo (TOTSCo, 2024). The process reduces administration, but it does not remove the need to check the planned switch date against an exam timetable.
If an assessment is imminent, the cautious option is usually to switch after it. Where an installation is needed, allow extra time for appointment availability and any property access issues. Read the order confirmation closely and contact the new provider promptly if the proposed date will not work.
Which connection type is best for a proctored exam?
Full fibre is the preferred choice where it is available and within budget, followed by a tested cable or other suitable fixed service. FTTC can still support many online exams, but its performance depends more on the line and home set up. 4G or 5G home broadband is best treated as an address specific alternative that needs proper testing.
| Connection type | Exam suitability | What to check | Practical verdict |
|---|---|---|---|
| FTTP, full fibre | Usually the strongest fixed option | Address availability and installation date | Choose first where available and fairly priced |
| Cable or altnet fibre | Can be well suited | Exact address coverage, contract terms and router location | Compare on total cost and expected service |
| FTTC | Often suitable for lighter household demand | Estimated speed, upload needs and Wi-Fi performance | Test before relying on it for an assessment |
| 4G or 5G home broadband | Useful where fixed options are limited | Indoor signal and consistency at exam time | Use only after testing at home |
What are the most common proctored exam broadband questions?
These answers focus on reducing risk before a timed assessment. The exam provider's own technical rules always take priority, particularly where it specifies browsers, camera checks, identification or permitted backup arrangements.
Can I use mobile data for a proctored exam?
You may be able to use 4G or 5G home broadband if the exam provider permits it and you have tested it thoroughly. Indoor signal can differ between rooms and can vary by time of day. A fixed connection is normally the lower risk choice when one is available and working well.
Should I choose download or upload speed?
Check both, but do not treat either figure in isolation. Proctored exams can use your camera, microphone and screen sharing, which makes consistent upload capacity relevant. The provider's technical guidance is the right source for the minimum requirement, then test your actual connection before the assessment.
Will changing broadband interrupt my exam?
It can if the activation date, router delivery or installation does not go as planned. Avoid scheduling a switch immediately before an exam. Keep your current service until the replacement is confirmed as working where the order terms and timing allow.
Do I need an engineer visit for full fibre?
It depends on the property and the network already present. Some addresses need installation work or an appointment, whilst others may be ready for activation. The provider's address level order journey should state whether an engineer visit is expected and offer the available dates.
What if my Wi-Fi is poor in my exam room?
Use Ethernet if practical. Otherwise, test the connection in that room, move closer to the router and reduce other household internet activity. Do not wait until the exam day to find out whether a distant room has weak or inconsistent Wi-Fi.
For a calm, evidence-based choice, enter your postcode in the BroadbandSwitch.uk comparison tool and check the broadband options, total contract terms and installation timing available for your exact address. Book only when the proposed start date leaves a sensible buffer before your assessment.
