BT broadband: what to check before you switch

Who BT is, and who it is not

British Telecommunications plc sells residential broadband as BT. It sits in BT Group, alongside EE and Plusnet. Those are separate retail brands. A BT order is not an EE mobile contract and not a Plusnet account, even when the wholesale trench under the pavement is the same.

BT is not Openreach. Openreach builds and maintains the access network and sells wholesale access to many retailers, including BT. When a BT advert says full fibre, it usually means Openreach fibre to the premises where that product has been released. It does not mean BT has strung its own cable down every street, and it does not mean a neighbour’s full fibre is yours.

OneTouchSwitch is not BT, not Openreach and not Ofcom. We do not take the order and we do not run the switch. The provider you choose does.

What a BT broadband product actually is

On the Openreach network BT can sell full fibre (fibre all the way to the premises) and older part-fibre, where fibre stops at a street cabinet and copper finishes the journey. The two are not the same product with different marketing. Part-fibre still depends on the length and condition of that copper. Full fibre removes that tail, but only on the speed tier written on the order, and only if the premises can take it.

A television package, a Halo-style extra, or a phone you no longer use can sit inside the same monthly conversation and still be a different decision. Price the connection on its own first. Then decide whether you want anything else. A landline that exists only because it was never removed is not a reason to buy a larger bundle.

Wi-Fi in the back bedroom is not the line. BT can supply a hub. Walls, floors and where that hub sits still decide what a laptop sees. If video calls fail in one room, fix the Wi-Fi before you assume you need a faster package.

Contract, rises and Home Essentials

BT has long sold both fixed-term broadband and a social tariff, widely known as Home Essentials. Eligibility, the current price and whether the tariff is exempt from ordinary rises are BT’s to confirm. We do not collect benefit letters and we do not quote a social-tariff price here, because that figure moves and it is not a commercial intro deal.

From 17 January 2025, Ofcom has required providers to set out in-contract rises for new deals in pounds and pence at the point of sale, rather than as an inflation formula you cannot calculate yet. Older BT contracts can still follow the wording you signed, which may differ. Read the rise on the order you are about to accept. Do not reuse a figure you saw on a comparison site last spring.

A lower price for a few months is not the cost of the contract. Ask what you pay after any introductory period, what happens in April if a dated rise falls inside the term, and what you would pay to leave early. An unknown exit fee is not zero.

Switching to or from BT

Where One Touch Switch applies, the new provider starts the process. You should not cancel BT first in the hope of a cleaner handover. Cancelling first can open a gap. BT does not pay your current early-termination charge unless they have put a waiver in writing. Get the figure in pounds from the provider you are leaving before you treat a BT offer as a saving.

Moving from Virgin Media, Hyperoptic, Community Fibre or another own-build network onto BT is usually a change of physical network, not a settings change. Expect the possibility of an engineer and a new socket. Moving from Sky, TalkTalk, Vodafone or Plusnet on the same Openreach line can be simpler, and still is not guaranteed until BT has matched the premises.

A phone number, a care alarm and any TV service need their own question. Keep the old router until the new service has been up for a few days. If the appointment needs someone at home, book a day you can actually be there.

When BT is the wrong shortlist

If the building is on a landlord-chosen network, or the street is only served by an alternative full-fibre builder, BT may have nothing to sell you. A national logo does not create an order. Check the flat number, not just the postcode. New builds and conversions fail automated matches more often than they should.

If you want a technical specialist, a static address, or a symmetrical product from a network BT does not use, this brand is the wrong tool. If you only wanted the cheapest rolling month and you will move in the spring, a long BT term can be the expensive choice even when the first bill looks calm.

How to read a BT offer now

A BT offer in late 2026 is still an Openreach order unless the checker says otherwise. Full fibre means the fibre reaches the premises Openreach has released. Part-fibre means the fibre stops at a cabinet and copper finishes the job. Those are different products with different upload, different fault patterns and, often, a different appointment. The brand on the van does not collapse them into one. Write down the technology name on the order, the speed tier, and whether an engineer has to enter the flat. A national coverage percentage is not that sentence.

Home Essentials is a social tariff with its own eligibility, not a discount code you apply to a commercial deal. Confirm the current product, who qualifies, and whether that tariff follows the same rise as a standard contract. We do not quote a figure, because it moves and it is not an introductory trick. Separate any BT TV or phone you do not use from the broadband line before you decide the monthly shape looks calm. A sister-brand mobile deal with EE exists only if the order says so.

Before you agree a date

Do not cease your current service because a neighbour’s full fibre went live. Match the flat number. Ask BT what happens if the install fails on the day. Keep the old router until the new line has stayed up. Get any exit fee from the provider you are leaving, in writing, before you treat the BT order as a saving. One Touch Switch is started by the new provider. OneTouchSwitch does not take the order.

The network BT actually sells

BT is British Telecommunications plc. BT is a BT Group retailer on the Openreach network, alongside EE and Plusnet as separate brands. BT is not Openreach. Openreach wholesales access to many retailers. BT can sell where Openreach has released full fibre or part-fibre for that premises. A national advert is not a release. OneTouchSwitch does not run that check and does not take the order.

BT will not sell a Virgin Media cable line, a Hyperoptic building, Community Fibre, or KCOM’s Hull network. A flat on someone else’s riser can come back empty. A postcode, a county, or a neighbour’s install is not a premises. Write down the flat or the plot before you read a speed.

If BT cannot order the door, the rest of this guide is a description, not a plan. Compare only the networks that can be installed. Leave the others off the list without drama.

The BT product, without the poster

Full fibre and older part-fibre are different products. Part-fibre still depends on the copper from the cabinet. The tier on the order is the service, not the fastest number in the campaign. Read the upload on the tier they will sell. Wi-Fi in the back room is not that figure.

A television extra or a phone you no longer use can sit in the same conversation. Price the line alone first. EE mobile is a sister brand and a separate contract unless the order joins them. One Touch Switch moves the fixed broadband process. It does not move television, a mobile handset, or a care-alarm contract.

Ask BT to name the technology and the tier in writing. An ‘up to’ speed on a different street is not the service. Wi-Fi inside the building is not the line.

How to read a BT price

This page lists no BT prices, rises, or social-tariff figures. Write the price after any introduction, how many months the opening price lasts, any upfront cost, and any in-contract rise stated in pounds and pence, with the month it happens. From 17 January 2025 that cash disclosure is what Ofcom requires on a new contract. Older contracts can still follow older wording.

Add the opening months, the rest of the minimum term, the upfront cost, and a stated rise only if it falls inside the term. Do not add a rise nobody has shown you. Do not subtract cashback you have not been paid. Do not treat a blank exit fee as zero.

BT has sold a social tariff widely known as Home Essentials. Eligibility and the current price are BT’s to confirm. This guide does not print them. A commercial discount is not a social tariff. Eligibility is the provider’s check. Do not send benefit letters to OneTouchSwitch.

Switching to or from BT

A move from another Openreach retailer can be remote. A move from cable or an alternative builder usually needs an engineer and someone at home. Where One Touch Switch applies, the new provider starts it. Do not cancel the old broadband first. Keep the old router until the new service has stayed up.

One Touch Switch does not cancel an early-termination charge. Ask the provider you are leaving for the figure in pounds. Unknown is not zero. Put that figure beside the new contract before you call the change a saving. A fee larger than the difference means staying to the end date is usually cheaper. You can still leave for a fault or a move. Just do not call it a saving.

A move of house is not a One Touch Switch of the old line onto a new street. BT at the old address is not evidence for the new one. Check the new premises again.

When BT service fails

Faults and missed dates sit with BT if they sold the service. Keep the promised date and the date it actually worked. This site does not pay compensation. Write the promised date and the date service actually worked. Those two dates are what a later conversation needs.

Automatic compensation, where a scheme applies, is paid by the provider, not by this website. We do not quote amounts, because they change, and not every product is inside the scheme in the same way. Ask them. Wi-Fi in one room is often the hub, not a line fault. Test on a wire near the router before you book an engineer for the line.

Complain to BT first if they sold the service. Ofcom is the regulator, not your first call. An independent scheme comes after their process, and only they can tell you which scheme they belong to. We cannot see the ticket and we cannot escalate it.

A BT decision, worked through

A converted house with three flats sees a BT full-fibre advert. Only a check of the flat, not the postcode, tells you whether Openreach full fibre, part-fibre, or nothing can be ordered.

BT belongs on a shortlist when Openreach can serve the premises and you want a national retailer with a known social-tariff question to ask. Skip BT when the building is on another network only, or when you need a specialist feature they will not sell.

Before either path, write down a phone number you need to keep, any television you meant to keep or drop, and any alarm that uses the line. Tell the alarm’s monitoring company yourself. BT will not do that job because a broadband order exists.

BT and the rest of the household bill

BT broadband is not an energy contract. A home move of the line does not move gas or electricity. Gas and electricity follow energy rules and a different regulator. One Touch Switch does not move them. A single direct debit does not make them one contract.

If a discount depends on keeping BT broadband beside another service, ask what happens to the discount when the broadband changes. Get the answer in writing. Price the line on its own first. Then decide about the other bill. Do not let a mixed advert pick the broadband term.

We do not publish energy unit rates, a model weekly bill, or a broadband tariff for this brand. The method is the thing that stays current. The numbers belong on the order, dated the day you sign.

What to confirm with BT now

Reviewed 5 November 2026. The network facts above are structural. The price is not. Ask BT four things on the same call: can you order this premises, what technology and upload, what is the price after any introduction and any stated cash rise, and what would I pay to leave my current contract.

If they cannot answer the first question, stop. If they can, write the other three down and only then compare. A published offer on OneTouchSwitch, where we show one, is still not this conversation. Their screen is the order.

OneTouchSwitch is not BT, not Ofcom, not Openreach and not the network owner. We will not claim an award, an official rating, a guaranteed saving, or a day with no downtime. If a sentence on this page goes stale, the provider’s current terms win, and we should correct the sentence.

A notebook before you call BT

Open a note before you speak to BT. Write the premises first: the flat or the plot, not only the postcode. Then write who you are dealing with, British Telecommunications plc, so a later bill is not confused with a sister brand or with the network owner. BT is a BT Group retailer on the Openreach network, alongside EE and Plusnet as separate brands. BT is not Openreach. Openreach wholesales access to many retailers. OneTouchSwitch does not make that call and does not take the order.

Under network, copy only what they will order at that door. BT can sell where Openreach has released full fibre or part-fibre for that premises. A national advert is not a release. BT will not sell a Virgin Media cable line, a Hyperoptic building, Community Fibre, or KCOM’s Hull network. A flat on someone else’s riser can come back empty. If BT cannot serve the premises, close the note. A speed from a poster is not a consolation row, and a neighbour’s install is not your order.

Under product, write the technology and the tier in their words. Full fibre and older part-fibre are different products. Part-fibre still depends on the copper from the cabinet. The tier on the order is the service, not the fastest number in the campaign. Read the upload on the tier they will sell. Wi-Fi in the back room is not that figure. A television extra or a phone you no longer use can sit in the same conversation. Price the line alone first. EE mobile is a sister brand and a separate contract unless the order joins them. Leave television, a handset and any care alarm on their own lines. One Touch Switch moves the fixed broadband process. It does not move those other contracts, and BT will not reprogram an alarm because a broadband order exists.

Under money, leave the cells blank until BT fills them on the day. You need the price after any introduction, how many months that opening price lasts, any upfront cost, and any in-contract rise stated in pounds and pence with the month it falls. Add the opening months, the rest of the minimum term, the upfront cost, and a stated rise only if it falls inside the term. Do not subtract cashback you have not been paid. Do not write zero for an exit fee you have not been shown. BT has sold a social tariff widely known as Home Essentials. Eligibility and the current price are BT’s to confirm. This guide does not print them.

Under the switch, write who starts it. A move from another Openreach retailer can be remote. A move from cable or an alternative builder usually needs an engineer and someone at home. One Touch Switch does not cancel an early-termination charge. Ask the provider you are leaving for the figure in pounds. Unknown is not zero. Keep the old router until the new service has stayed up. A house move is a new premises, not a transfer of the old BT order onto a new street.

Under service, write the promised date and, later, the date it actually worked. Faults and missed dates sit with BT if they sold the service. Keep the promised date and the date it actually worked. This site does not pay compensation. Where Ofcom’s automatic compensation scheme applies, the provider pays the published amount. This website does not. Not every product is inside the scheme in the same way. Ask BT whether this order is, and keep the reply.

Under the household, write the scene you are actually in. A converted house with three flats sees a BT full-fibre advert. Only a check of the flat, not the postcode, tells you whether Openreach full fibre, part-fibre, or nothing can be ordered. BT belongs on a shortlist when Openreach can serve the premises and you want a national retailer with a known social-tariff question to ask. Skip BT when the building is on another network only, or when you need a specialist feature they will not sell. Before either path, write down a phone number you need to keep and anyone who depends on the line. Tell them yourself.

Under other bills, keep energy off the broadband line. BT broadband is not an energy contract. A home move of the line does not move gas or electricity. Gas and electricity follow energy rules and, in Great Britain, a different regulator. One Touch Switch does not move them. A discount that needs both services is a second decision: ask what happens to it if the broadband changes. Reviewed 5 November 2026. The structure of this note stays. The figures BT gives you are the only prices that belong in it.
