Next update: when BT changes its public Full Fibre 900 price or its reward card.
By: Switch Editorial Team, Switch Squid Ltd
BT Full Fibre 900 price check: BT’s own deals page lists Full Fibre 900 at £33.99 a month (checked 24 October), and the buttons below open BT’s Full Fibre 150 offer at £23.99, rising to £27.99 from March 2027 and £31.99 from March 2028, £0 activation. When the 24 months end, BT says your price goes up by no more than £5 a month unless you sign a new contract. BT often adds a reward card, so check the current one through our link. Prices and reward cards can change, so the amount in your BT basket is the one that counts.

What Full Fibre 900 means on Openreach
Full Fibre 900 is BT’s ~900 Mbps-class FTTP consumer package on Openreach where the build is live. It is not a copper last-mile “up to” product. If your address can only get part-fibre (FTTC) broadband, that speed isn’t available to you until full fibre is installed. Always run BT’s postcode / address checker before you fall in love with a speed name.
October is when summer moves finish, student lets settle, and winter WFH returns. Prices can change at any time, so check the monthly price, any activation fee and the price rises in your BT basket on the day you order. That total is the one that counts.

What to check before you order
BT updates its broadband prices and reward card offers from time to time. On the day you order, check: (1) the package is still called Full Fibre 900, (2) the monthly price, (3) any activation fee, (4) any reward card and its claim deadline, and (5) the 31 March price rises.
Believe the basket you can actually order on purchase day. If two BT pages show different prices, go by the total in your basket at checkout, not a third-party screenshot.
Working out your first-year cost
1) Confirm FTTP at your exact address. 2) Write down busy-hour upload needs (Teams, cloud backups, cameras). 3) Add setup, courier, and router fees to the headline monthly. 4) Add BT’s £4-a-month rise from 31 March 2027. 5) Price exit fees if you still have months left on the old contract. 6) Then check availability and order.
A “cheap” 150–500 Mbps full-fibre that actually reaches your address often beats a 900 Mbps plan you can’t get at your address. Speed tests after install matter more than brochure Mbps — keep the order confirmation and photo the engineer’s light levels if you later need a fault ticket.
Leaving fees, One Touch Switch and voice lines
We already published a dedicated BT Full Fibre 900 leaving fees guide — read it if you are exiting early. For clean switches, keep the old service live until the new ONT lights green. Export router settings and IoT static leases. Care alarms and lift lines that still assume an analogue path need an explicit plan before you cancel copper.
One Touch Switch improves the consumer switching journey when providers support it, but it can’t bring fibre to streets Openreach hasn’t built to. Availability still wins.
Upload, mesh Wi-Fi and the last ten metres
Brochure download Mbps sell dreams; upload and Wi-Fi kill mornings. Cloud photo backups, security cameras and two simultaneous Teams calls care about upload and airtime interference more than a 900 Mbps WAN LED. Budget for a mesh kit if your floors are thick Victorian brick. Put the hub in a central open space, not a metal cupboard under the stairs. If BT’s hub in modem mode plus your own access points is the plan, confirm that BT supports it on Full Fibre 900 before you turn down BT’s equipment.
Latency for gaming and VoIP is usually fine on healthy FTTP. Congestion appears at busy-hour contention on some shared segments — keep a weekend evening speed-test habit for the first fortnight and raise a fault with timestamps if you are far below the order speed.
Reward cards and set-up fees
BT often adds a reward card to its broadband deals, and the amount changes from time to time. If your basket shows a reward card, screenshot the terms and put the claim deadline in your diary, because you usually have to claim it yourself. A reward card you never claim saves you nothing.
A £0 activation fee helps, but only if the monthly price and rises still beat a rival full fibre deal at your address. Never let a £0 activation badge override a bad rise clause.
Landlords, students and who holds the contract
October student lets and landlord recharge clauses create messy cease charges when the named account holder leaves mid-term. Decide who holds the broadband contract before you order. Photograph the ONT after install so the next engineer is not guessing which fibre drop is live. Export any ISP email you still care about on day one — ISP mailboxes die quietly.
BT Full Fibre 900 or a wider comparison?
Our full fibre broadband deals UK October 2026 guide compares BT with other full fibre providers, including smaller local networks. This page is for people who have already settled on BT Full Fibre 900 and want the price, rises, reward card and set-up detail in one place.
If BT full fibre isn’t available at your address, check Virgin Media and local full fibre providers instead. Your postcode decides what you can actually order, whatever national headline prices say.
Engineer day checklist
Clear access to the master socket / proposed ONT wall, photograph the street cabinet reference if you have one, and be home for the appointment window. Keep pets and kids clear of fibre bend-radius drama. After lights go green, run a wired speed test before you blame Wi-Fi. If figures are far below the order speed for two busy evenings, open a fault with timestamps — not a vague “it’s slow” ticket.

FAQ
What is the best BT Full Fibre 900 deal October 2026?
As of 24 October 2026, BT Full Fibre 900 costs £33.99 a month for 24 months with £0 activation. It rises to £37.99 from 31 March 2027 and £41.99 from 31 March 2028, so include that in your sums. Check availability at your postcode first.
Why might other sites still show a higher Full Fibre 900 price?
Third-party cards and older screenshots lag. BT’s own deals page lists Full Fibre 900 at £33.99 a month (checked 24 October); our links open BT’s Full Fibre 150 offer at £23.99, so re-check prices on the day you order. BT often adds a reward card, so check the current one through our link.
Is 900 Mbps necessary?
Often no. Multi-4K + heavy upload WFH can want high tiers; a single-WFH household often thrives on 150–500 Mbps full fibre.
Why BT and not Virgin / Hyperoptic?
BT Full Fibre uses Openreach’s network, which reaches many streets that Virgin Media and Hyperoptic don’t. Where Virgin Media or Hyperoptic is available, compare their first-year cost too, as they can be cheaper at similar speeds.
Do BT’s prices go up during the contract?
Yes. BT Full Fibre 900 goes up by £4 a month each 31 March: to £37.99 from 31 March 2027 and £41.99 from 31 March 2028. BT shows these rises before you order.
Does full fibre need a phone line?
Classic FTTP installs are data-led; voice is optional VoIP on many packages. Confirm during order if you still need a landline number for alarms.
Do you earn money from these links?
Our deal buttons link to BT, and we may earn a commission if you buy. That does not change the price you pay. Always check the plan name, data, price and key allowances on the retailer’s site before you pay. Compare the options on this page first, then use a deal button when you’re ready to buy.
SwitchSquid may earn a commission if you buy through links on this page. It doesn’t change the price you pay. Always check the plan, contract length and fees in your BT basket before you pay.
