Short answer: Broadband options for a new-build where nothing is live yet depend on which network has been built to your address and whether its records are ready. Ask the developer first, then check the full address with providers. Order early if installation is needed, and keep a temporary option in mind for moving week.

- A new property can be connected physically but not yet ready to order.
- Your postcode alone may not distinguish one new home from another.
- Full fibre, cable and fixed wireless home broadband are all worth checking where available.
- Do not cancel an existing connection until you know your move date and installation plan.
A family moving into a newly finished estate may find that the sales office has Wi-Fi, yet their own address returns no results. That does not automatically mean the estate has no broadband route. It can mean the property reference, plot number or network handover is still being processed. The useful question is not simply, “Which provider is best?” It is, “Which network serves this exact home, and when can it accept an order?”
Why is no broadband showing at my new-build?
A missing result often means the address record or network handover is not ready, rather than that your home cannot be connected.
New-build addresses can appear differently across systems while plots are becoming postal addresses. Try the full address exactly as supplied by the developer, then ask whether there is a final house number, plot reference or postcode format you should use. Do not assume a nearby neighbour's result applies to you: two homes on the same street can be connected by different routes or completed at different times.
Ask the developer which network infrastructure was installed, whether a network termination point has been fitted inside the home, and whether any work remains before orders can be placed. A network termination point is the small fixed connection point where a fibre service enters the property. Keep any written response and the development plan. It gives a provider useful detail if an address check fails.
Which broadband options can a new-build have?
Start with the built network, then compare the services that can actually be ordered at your address.
Full fibre, also called fibre to the premises or FTTP, runs fibre to your home. It is commonly installed in new developments, but availability still depends on the specific address being released for ordering. Cable may be available on some developments, while fibre to the cabinet or FTTC may appear where older copper-based infrastructure serves the site.
An alternative network, often shortened to altnet, is a separate network operator that may serve a development alongside, or instead of, another network. Fixed 4G or 5G home broadband uses a router at your property and can be useful where a wired service is delayed, subject to coverage and indoor signal. Ofcom reported that 82% of UK homes could access full fibre on 13 May 2026 (Ofcom, 2026, Connected Nations Update). That national figure cannot confirm service at an individual new-build.
| Option | What it uses | Best question to ask | What to check |
|---|---|---|---|
| Full fibre (FTTP) | Fibre to the home | Is this address ready to order? | Whether an installation visit is required |
| Cable | A cable network to the property | Does this plot appear separately? | Address matching and installation access |
| FTTC | Fibre part way, then existing line to the home | Is a line already present? | Installation requirements and estimated service |
| 4G or 5G home broadband | Mobile network signal to a home router | Is indoor coverage suitable at this address? | Signal in the rooms where you work |
Should I order broadband before moving day?
Yes, once you have a confirmed address and access date, because a new connection may need checks or a visit.
Ordering early gives time for address records to be corrected and for any installation appointment to be arranged. It does not guarantee that a service can start before you collect the keys, so avoid planning critical home-working around an unconfirmed activation date. If you rent, check what access the landlord or managing agent requires for work inside the property or in shared areas.
Read the order summary carefully before you commit. Look for the contract length, one-off charges, equipment returns, start date wording and the pounds-and-pence amount of any future annual price rise. Since 17 January 2025, new contracts must show any mid-contract price rises in pounds and pence at the point of sale, rather than linking them to inflation (Ofcom, 2025, 17 January).
What should I ask the developer or site manager?
Ask for the network name, the status of your exact plot and who can confirm that orders are open.
Start with whether the home has been connected externally and whether the internal termination point is in place. Ask whether the street name and house number are final, whether there is a building reference that providers should use, and whether the site has restrictions on installation work. For a flat, ask who controls risers, communal cupboards and access to shared areas.
Do not rely on a verbal assurance that broadband is “coming soon”. Ask what is complete, what is outstanding and who owns the next action. If the developer says a service is live but an address search says otherwise, provide the exact address details back to the developer and ask them to raise it with the relevant network.
Can I use a temporary connection while I wait?
Possibly, but treat it as a bridge and test whether it works inside your home before relying on it.
4G or 5G home broadband can suit a short delay where coverage is good, particularly if you need a connection for basic household use or a home office. Signal can vary between rooms, floors and new-build insulation, so a coverage indication is not the same as a test from your desk. Consider how much data you need, how long the delay might last and whether the arrangement has a short commitment.
If your current home still has broadband, keep it active until the move is certain where practical. Moving-home arrangements can differ from a standard switch because the new address may not yet have an active service to take over.
What happens once a wired service is live?
Once your address can accept an order, compare the available options on total terms rather than assuming the first result is the only choice.
Check the stated monthly charge, contract length, installation details and any known annual increases. Think about the people using the connection: several home workers, video calls and a busy household may have different needs from a couple who mainly browse and shop online. A speed estimate is useful context, but it is not the only factor in a satisfactory connection.
If you later move from one active provider to another at the same address, One Touch Switch means you contact the new provider rather than your old one. The process went live on 12 September 2024 and is run by TOTSCo (TOTSCo, 2024, 12 September). For a brand-new inactive address, the immediate task is usually getting the first service live.
What to do next
- Ask the developer for the network details, final address format and plot status.
- Decide whether you need a temporary home connection for the first days or weeks after moving.
- Check your exact postcode and address, not just the development name.
Frequently asked questions
Can I choose any broadband provider on a new estate?
No. You can choose only from providers using a network that serves and accepts orders for your exact address. A development may have one available network, several, or an address record that is still incomplete. Checking the final address is more reliable than choosing based on advertising aimed at the wider area.
Why does my neighbour have broadband but I cannot order it?
Completion dates, address records and physical connections can differ between plots. Your neighbour may also be served by a different network route. Give the developer and the provider the exact house number, postcode and plot reference if you have one, then ask whether the issue is address matching or outstanding work.
Do I need a landline for new-build broadband?
Not necessarily. The old PSTN landline network closes on 31 January 2027, so do not assume a traditional phone line will be installed or required for a new service. If you need a home phone for a specific purpose, ask how it would work with the broadband option you are considering.
How long does a new-build broadband installation take?
There is no single reliable timeframe. It depends on whether the network is ready, whether the address is recognised and whether an engineer visit or site access is needed. Order once your details are confirmed, but make a temporary plan rather than treating an estimated date as guaranteed.
