The cheapest BT broadband deal at our sample address in November 2026 was Fibre 300 broadband only at £26.99 a month once its reward is counted, and the best value for most homes was Fibre 900 broadband only at £28.99. Every BT deal rises by a fixed £4 a month each 31 March,12 so judge them on the 24-month total, not the starting price.
Prices below were checked on 14 November 2026 at a sample UK address, and on BT.com on 1 November 2026. Your price depends on your postcode, and the rewards on these deals end at 11.59pm on Thursday 19 November 2026.1

Who each deal suits
- Fibre 300 broadband only. A couple or small family who stream and work from home without needing the top speed or a landline. It’s the cheapest BT deal on the list once rewards are counted: Fibre 150 starts £1 lower but costs £26 more over 24 months, because its reward is only £80.
- Fibre 900 broadband only. Bigger households, gamers and anyone uploading large files. Our BT Full Fibre 900 review covers real-world performance.
- Fibre 300 & phone. Anyone who still makes calls on a home phone and wants the cheapest BT line. Our BT Full Fibre 300 review goes into detail.
- Fibre 500 & phone. A household that wants a landline and more speed; it costs only £1 a month more than the 300Mbps phone deal and comes with a £10 bigger reward.
- Fibre 900 & phone. The fastest BT deal with a landline, for busy homes that still need the phone.
Buying direct from BT.com
BT.com sold the same speeds at slightly different prices, with no gift-card rewards, and shows a guaranteed minimum on each plan, from 150Mbps on Full Fibre 300 to 700Mbps on Full Fibre 900.2
BT’s own site sold the same speeds at slightly different prices when we checked it on 1 November, with no gift-card rewards. It does show each plan’s guaranteed minimum speed, which the table above doesn’t.2
BT.com broadband prices and guaranteed speeds, November 20262
| Plan | Speed (guaranteed) | Monthly price | Rises on 31 March | 24-month total |
|---|---|---|---|---|
| Full Fibre 150 | 150Mbps | £30.99 | £34.99, then £38.99 | £847.76 |
| Full Fibre 300 | 300Mbps (150Mbps) | £32.99 | £36.99, then £40.99 | £895.76 |
| Full Fibre 500 | 500Mbps (425Mbps) | £32.99 | £36.99, then £40.99 | £895.76 |
| Full Fibre 900 | 900Mbps (700Mbps) | £33.99 | £37.99, then £41.99 | £919.76 |
| Fibre 2 (part fibre) | 74Mbps (34Mbps) | £29.99 | £33.99, then £37.99 | £823.76 |
| Fibre 1 (part fibre) | 50Mbps (25Mbps) | £28.99 | £32.99, then £36.99 | £799.76 |
| Fibre Essential (part fibre) | 35–36Mbps (32Mbps) | £28.99 | £32.99, then £36.99 | £799.76 |
Three things stand out. Full Fibre 500 cost the same as Full Fibre 300 on BT.com, so the faster plan was the obvious pick. Every plan had a £0 set-up cost when ordered online.2
And the part-fibre plans, which run over the copper line from the street cabinet on the Openreach network, cost almost as much as full fibre: if full fibre reaches your home, it’s the better deal.2
The deal cards don’t mention a landline, but BT’s legal notes answer it: “Unless you have added Digital Home Phone, there is no call service included when you purchase home broadband.”3 So these BT.com prices are for broadband without a home phone; you add Digital Home Phone if you want one.
New customers get the BT Smart Hub 3 unless they already have a Smart Hub 2.3
What comes with every BT deal
Every BT deal includes a guaranteed minimum speed, the Stay Fast Guarantee, a Smart Hub 3 for new customers and threat protection that BT values at £80 a year.23
Whichever deal you choose, BT.com lists the same core extras. These are worth counting when you compare BT’s price with a cheaper rival.
- A guaranteed minimum speed. Each plan shows one, such as 700Mbps on Full Fibre 900.2 If speeds regularly fall below it after BT’s fixes, you can leave without an exit fee.4
- The Stay Fast Guarantee. If BT can’t restore your promised speed to the hub within 30 days, it pays a £20 Reward Card, up to four times a year.3
- The Smart Hub 3. New customers without a Smart Hub 2 get BT’s Wi-Fi 6 router.3
- Threat protection. BT says its advanced threat protection is “worth £80 a year” and is included with every broadband plan at no extra cost.2
- No activation fee online. Every BT.com plan showed a £0 activation fee for online orders.2
Optional extras cost more. Complete Wi-Fi adds Wi-Fi discs, with “£100 back” if you don’t get a reliable signal in every room. Hybrid Connect keeps you online over a mobile network if your broadband goes down.
BT.com’s deals page didn’t show prices for either. BT’s price guide effective from 25 September 2026 lists Hybrid Connect at £10 a month on a 30-day term, and prices packages with Complete Wi-Fi £10 a month higher.5 BT’s Halo page still says £7 for Hybrid Connect, so check your basket.6
Switching to BT
If you’re with another broadband provider, you usually don’t need to contact them: under Ofcom’s One Touch Switch, BT arranges the switch and your old service should end once the new one works.7 Ofcom says One Touch Switch has been used by over 2 million customers since it launched in September 2024.8
Check your current contract end date first, because your old provider can still charge an early exit fee. That’s where BT.com’s Full Fibre 150 offer helps, with up to £300 towards leaving fees as bill credit.2
BT TV and broadband bundles
BT’s TV bundles add Entertainment, Sport or Full Works TV to Fibre 900, and at our sample address they rose by £6 a month each spring rather than the £4 on broadband alone.1
BT relaunched BT TV on 15 October 2026. BT says TNT Sports and Netflix are available across its range, with a BT TV Box Pro or Box Edge, and you can change TV packages month to month.9
BT TV and broadband bundles at a sample UK address, November 20261
| Bundle | Monthly price | Rises on 31 March | 24-month total |
|---|---|---|---|
| Entertainment TV + Netflix + Fibre 900 (no phone) | £40.99 | £6, then £6 | £1,139.76 |
| Entertainment TV + Netflix + Fibre 900 & phone | £45.99 | £6, then £6 | £1,259.76 |
| Sport TV + Fibre 900 (no phone) | £52.99 | £6, then £6 | £1,427.76 |
| Full Works TV + Netflix + Fibre 900 (no phone) | £111.99 | £6, then £6 | £2,843.76 |
Each carried a £150 reward. Note that BT’s TV bundles rise by £6 a month each spring, not the £4 on broadband alone. Entertainment TV with Netflix added £12 a month to Fibre 900.1 Our guide to broadband and TV bundles shows when a bundle beats buying TV separately.
What a BT deal really costs
A BT deal costs more than its starting price: broadband rises by a fixed £4 a month each 31 March, and a phone line added about £5 a month at our sample address.21
The £4 spring rises
BT’s mid-contract price rise is fixed in pounds: £4 a month on 31 March 2027 and again on 31 March 2028.2 Ofcom has required this since January 2025: providers must set out rises “in pounds and pence, before you sign up”.10
On a contract starting in November 2026, the two rises add £104 to what you’d pay at the starting price. That’s why the equivalent average monthly cost of Fibre 900 broadband only is £33.32, not £28.99.
Rewards and when they end
The rewards in the first table are all due to end at 11.59pm on Thursday 19 November 2026.1 BT.com says Reward Card offers must be claimed within three months of placing the order, so check how your reward is paid and claim it promptly.3
Take the reward off the total to compare deals fairly: Fibre 900 broadband only drops to £649.76 once its reward is counted.
Adding a phone line
At our sample address the phone line added £5 a month to Fibre 900, or £120 over 24 months.1 Unless you use the home phone, broadband only is the cheaper choice. Our guide to broadband and phone deals compares line rental across providers.
When your contract ends
BT says your price will rise “by up to £5” a month once your minimum term ends,3 and later rises fall on 1 March.4 Ofcom found in-contract customers spend between £7 and £9 a month less than out-of-contract customers, so don’t drift.8
If you want to leave before the end of the term, read leaving BT early first: the early termination fee is roughly what you’d still owe for the rest of the contract.4
BT deals for existing customers and low incomes
Existing customers can use these new-customer prices to negotiate near the end of their contract, and households on certain benefits can get BT Home Essentials from £16.50 a month.11
The prices in this guide are for new customers. Near the end of your contract, compare the table above with what BT offers you, and use it to negotiate a better deal. If you’d rather talk to someone, contact BT on the numbers in our customer service guide.
If you receive Universal Credit, Pension Credit (Guarantee Credit), Employment and Support Allowance, Jobseeker’s Allowance or Income Support, look at BT Home Essentials instead. BT says its fibre plans “start from £16.50 with no set-up fees”, on a 12-month contract you can cancel at any time without exit fees.11
How BT’s deals compare with rivals
At our sample address BT Fibre 900 was the most expensive of five 900Mbps-class deals after rewards, and Vodafone Full Fibre 910 was the cheapest.1
BT against rivals at a similar speed, sample UK address, November 20261
| Deal | Monthly price | 24-month total | Reward | After reward |
|---|---|---|---|---|
| BT Fibre 900 broadband only | £28.99 | £799.76 | £150 | £649.76 |
| EE Full Fibre 900Mb | £25.99 | £727.76 | £150 | £577.76 |
| Plusnet Full Fibre 900 | £26.99 | £751.76 | £150 | £601.76 |
| Vodafone Full Fibre 910 | £24.50 | £679 | £140 | £539 |
| Sky Full Fibre Gigafast (line included) | £28 | £672 | £100 | £572 |
Vodafone rises by £3.50 each April; EE and Plusnet by £4 each March. Sky’s rises aren’t fixed in advance, so its total assumes no rise. On these figures BT’s 900Mbps deal was the most expensive of the five after rewards, £110.76 above the lowest total. Vodafone’s reward ends at 8.59am on Wednesday 18 November 2026; the others end at 11.59pm on Thursday 19 November.1
So when is BT worth the extra? When you value its written minimum speeds, the Stay Fast Guarantee and the Smart Hub 3. Our full BT broadband review weighs those against the price, and you can compare every broadband provider in our providers hub.
