How to Get Broadband in a New Build Home

How to get broadband in a new build home usually comes down to three steps: confirm which network already serves the property, pick a broadband provider that uses that network, then place your order so the connection is switched on. Most new build homes in England, Scotland and Wales are now built with gigabit-capable fibre to the premises (FTTP) already installed, so there is often no engineer visit and no digging required.

The fibre cable and the small ONT box are typically fitted by the developer before you move in. Having the cable in the wall is not the same as having a live service, though. You still need to choose a deal and order it.

• Check who wired the estate (most use Openreach; some use City Fibre, Virgin Media or another network).
• Compare broadband deals available on that network and place an order 2 to 4 weeks before moving day.
• If your address is too new to appear in checkers, ask the developer for the build details and use 4G or 5G home broadband as a short-term fix.

Why most new builds already have fibre installed

Most new build homes in the UK are built with gigabit-capable fibre infrastructure because the law now requires it. The Building etc. (Amendment) (England) (No. 2) Regulations 2022 came into force on 26 December 2022 and require developers to install gigabit-ready physical infrastructure and, subject to a £2,000 per-dwelling cost cap, a working gigabit-capable connection in new homes in England.

The same requirement was introduced in Scotland from 1 January 2025 and in Wales from 1 July 2025. In practice this means new estates are normally laid with FTTP rather than older copper lines.

The coverage data backs this up. According to thinkbroadband analysis published in June 2026, new build properties reached around 99% full fibre coverage across 2025 and 2026, well ahead of the wider UK figure of about 84.8% full fibre availability as of 19 June 2026. New builds tend to be ducted with accurate plans, which makes fibre rollout to them faster than to older housing stock.

What the developer installs versus what you arrange

The developer installs the physical fibre and the ONT box on your wall, but you arrange the live broadband service yourself. The ONT (optical network terminal) is the small unit your router plugs into. It needs a permanent 240-volt mains supply, so an electrician will normally have wired a socket nearby.

You then choose a broadband provider, place an order and a router is sent to you by post. First-time activation on a new build FTTP line is usually free and does not need an engineer to visit, because the cabling is already in place.

How to find out which network serves your new build

To find out which network serves your new build, ask the developer or site sales office which infrastructure operator wired the estate, then run that company’s online address checker. Most developments use the Openreach FTTP network, but some are wired by CityFibre, Virgin Media, Hyperoptic or a smaller alternative network (an altnet).

This matters because the network decides which providers you can choose. On an Openreach FTTP estate you can pick from a long list of broadband providers, including BT, Sky, Plusnet, Vodafone and many others. On a Virgin Media or single-altnet estate, your choice may be limited to that one operator’s packages until another network arrives.

• Ask the housebuilder for the network operator and the predicted connection date.
• Ask a neighbour who has already moved in which provider they managed to order.
• Run the address through the network operator’s own availability checker, not just a single provider’s site.

Why your new build address may not show up on checkers

A new build address often fails broadband checkers because the property has not yet been registered in the network operator’s address database. Openreach and other networks can only take orders to a recognised address that is mapped to a line reference, so until the postcode and plot are loaded, checkers may return “address not found” or “no service available” even when the fibre is physically there.

This is one of the most common new build broadband problems, and it usually resolves within a few weeks of completion as the address is added. If it drags on, contact the developer and ask them to confirm the address has been registered with the network operator. Openreach also runs a dedicated help route for residents in new build homes whose phone or broadband is not working.

Steps to take if you are stuck without service

If your new build has no broadband and the address will not register, push the developer first, then consider a fallback connection. The Universal Service Obligation (USO) gives most UK homes a legal right to request a decent broadband connection of at least 10 Mbps download and 1 Mbps upload, with BT (and KCOM in Hull) as the universal service providers, subject to a cost threshold of £3,400 per premises.

The USO is mainly a rural and remote safety net rather than a new build tool. It does not apply if your home is due to be connected by a funded rollout within 12 months, which most new builds are. Use it only as a last resort once the developer and network operator routes are exhausted.

Getting broadband in a new build house: the ordering process

Getting broadband in a new build house follows a clear order: confirm the network, compare deals on that network, place your order around 2 to 4 weeks before you move, then plug the posted router into the existing ONT on activation day. Because the fibre is pre-installed, most first-time FTTP connections go live without an engineer appointment.

1. Confirm the network operator with the developer.
2. Compare broadband providers available at the address.
3. Order with your move-in date as the start date.
4. Receive the router by post before you move.
5. Connect the router to the ONT and activate.

If you are moving from an existing property, you can sometimes carry an existing deal across, but a fresh order is usually cleaner on a new build. Our guide to switching broadband when moving home explains how start dates and notice periods work.

How much does broadband cost in a new build?

Broadband in a new build typically costs somewhere in the low £20s to around £40 a month for full fibre from national providers in 2026, with entry-level full fibre plans on the Openreach network among the cheapest options; check the provider’s current price at your address before you order. Faster gigabit tiers and broadband-and-TV bundles cost more, often £30 to £80 a month depending on speed and content.

New build FTTP lines can support fast speeds. Openreach markets full fibre speeds of up to 1,600 Mbps to developers, and some retail plans advertise speeds beyond 2 Gbps depending on the address. Most households do not need the top tier, so a mid-range full fibre plan is usually better value.

Watch the contract terms as well as the headline price. Many providers apply an annual in-contract price rise each April, and out-of-contract prices can jump sharply, so check the increase and the contract length before you commit. If you are comparing a specific package, our Sky superfast broadband guide shows how speed tiers and pricing compare.

How to get temporary internet while you wait

The fastest way to get temporary internet in a new build is 4G or 5G home broadband from a mobile network, which can deliver around 30 to 300 Mbps with no installation and no fibre activation wait. You plug in a mobile router, insert a data SIM and connect over the mobile network, which is useful when your address has not yet registered for fixed-line service.

A short rolling contract or a 30-day plan suits this best, so you are not tied in once your full fibre line goes live. Tethering from a phone hotspot can also bridge a gap for a few days, though data allowances and battery life make it less suitable for working from home or streaming over weeks.

Setting up your home network once you are connected

Once your broadband is live, position the router centrally and use the pre-wired data points if your new build has them. Many new builds include internal network cabling running back to a panel near the ONT, which lets you wire rooms with Ethernet rather than relying only on Wi-Fi.

If Wi-Fi struggles to reach every room, a mesh system or wired access points usually fix coverage better than a single router. Plugging a router into the ONT and into a network switch lets you feed multiple rooms cleanly from one connection.

Choosing a broadband provider on a new build estate

To choose a broadband provider on a new build estate, list the providers available on your network, then compare price, contract length, speed and the annual price rise rather than the headline figure alone. On an open Openreach FTTP estate you have wide choice; on a single-network estate your options may be limited until a second network is built out.

Compare like for like by checking the advertised average speed, the total cost over the full contract and any setup fee. If you switch providers later, the process is straightforward on shared networks, and our guide on how to switch broadband providers walks through notice periods and timing.
