The cheapest full fibre deals are not always the packages with the lowest headline monthly price. Compare the whole contract cost using date-stamped examples and the LinkSpeed total-cost calculator.
Full fibre value guide
Start with what your postcode can actually buy, then compare every price period, upload capability, setup charge and confirmed reward across the minimum term.
Commercial comparison with visible dates
Network availability, package speed, setup charges, annual price changes, rewards and location-specific discounts can change the winner. The table below is a small set of official-provider advertised examples checked on 5 August 2026, not a claim that every UK full-fibre package is included.
Postcode first, price second
The first price filter is physical availability. UK full fibre is supplied across several networks, and the cheapest provider in one street may not be able to serve the next.
One fibre network can support several competing retail brands at the same address.
What this means: where Openreach FTTP is live, several retailers may compete on price, contract terms, router and extras.
A different physical network can unlock a different price structure and much stronger upload options.
What this means: if an Alt-Net reaches the property, it may undercut mainstream FTTP or offer symmetrical upload at a similar price.

Upload speed can change the value equation
Two packages can advertise the same download speed but deliver very different upload performance. That matters when the household regularly sends large files, backs up to the cloud, hosts video calls or uploads high-resolution video.
The advertised upload and download rates are the same, or very close. toob currently advertises 900 Mbps down and 900 Mbps up on home900, while Hyperoptic advertises symmetrical speeds on eligible 150 Mb to 1 Gb packages depending on location.
Download speed is much higher than upload speed. This is common on many mainstream residential FTTP packages and can still be completely suitable for streaming, browsing and gaming.
Original LinkSpeed framework
Use the advertised monthly price as the starting point, not the answer. A fair comparison follows every cost and confirmed credit through the whole minimum term.
*Illustrative 24-month example only. Use the calculator below with the provider's actual order summary.
Buy the tier you will actually use
The cheapest useful deal is usually better value than the cheapest maximum-speed deal. Choose the lowest tier that comfortably covers the household, then enter that package's real price periods into the calculator below.
Usually enough for a small household browsing, using video calls and running one or more 4K streams without paying for capacity that sits idle most of the day.
Best price goal: minimise the monthly bill.A strong middle tier for simultaneous streaming, home working, cloud use and faster console or PC game downloads across several active devices.
Best price goal: balance total cost with headroom.Useful for very large downloads, frequent high-volume uploads and households where several people move big files at once. It does not by itself guarantee lower ping or eliminate peak-time congestion.
Best price goal: check upload speed and router capability before paying the premium.See the full LinkSpeed speed-needs guide for a more detailed household calculation.
Enter the figures from the provider's order summary. Add each price period separately so a scheduled rise is not hidden by the launch price. The result shows both the gross provider spend and the net effective cost after a confirmed reward or credit.
The loyalty-penalty check
The minimum-term winner can stop being cheap as soon as the promotional contract ends. Always record the provider's stated post-contract price as a separate figure and compare it with the cost of re-contracting or switching.

£192 extra over 12 months
Illustrative example only — not a live provider quote. Check the actual post-contract price shown by the provider.
Common comparison mistakes
A low launch price can hide a scheduled pounds-and-pence increase later in the minimum term.
A gift card is not the same as a lower direct-debit amount. Compare gross provider spend and net effective cost separately.
Activation, installation, router delivery and required hardware can change the real first-year cost.
Check that the exact address receives full fibre to the premises rather than part-fibre FTTC. Then confirm the advertised provider actually serves that postcode: an attractive Alt-Net price is irrelevant if only another physical network reaches the property.
The cheapest minimum-term deal can become expensive after the term ends. Record the end date and review before the out-of-contract price starts.
Final buying check
Confirm that the exact address receives FTTP/full fibre rather than part-fibre FTTC.
Record every monthly price period inside the minimum term.
Add activation, installation, delivery and required equipment.
Subtract only a reward you are eligible for and likely to claim correctly.
Compare effective monthly cost with the speed, upload rate, router and service features you need.
Check what the price becomes after the minimum term and set a reminder before it ends.
Quick answers
There is no single cheapest full fibre broadband deal for every UK address. Availability, contract length, scheduled price changes, setup charges and rewards vary, so compare the total minimum-term cost for the exact address.
Add the cost of every monthly price period in the minimum term, then add setup, installation, delivery and required equipment. Subtract only a confirmed reward or bill credit you are eligible to receive, then divide by the contract months to compare effective monthly cost.
No. Since 17 January 2025, new UK telecoms contracts cannot use inflation-linked or percentage-based in-contract price rises. If a provider includes a scheduled rise, it must state the increase clearly in pounds and pence before you sign up. Older contracts can still contain legacy percentage or inflation-linked terms.
Only include a reward when you are eligible for it and are confident you will claim or receive it. Compare the gross provider spend as well as the net effective cost after the reward so a promotional incentive does not hide the underlying contract price.
Not always. A slightly higher-priced package can be better value if it includes the upload speed, router capability, support, installation terms or service features you actually need. Compare total cost and service quality together.
Yes, for eligible households it can be. Ofcom's social-tariff list currently includes packages from £10 to £24 per month. Eligibility and available speed vary by provider and address, and a social tariff is not automatically an FTTP package.
They can be for upload-heavy households because the advertised upload rate matches, or nearly matches, the download rate. That is useful for cloud backups, large file transfers and content creation, but it does not automatically improve gaming latency.
Many annual telecoms price changes are applied in March or April. For new contracts, any scheduled in-contract increase must be shown upfront in pounds and pence together with when it will happen, so use the order summary rather than assuming a standard date.
Transparency
Each example links to an official provider page and carries a checked date. Expired promotions should be removed or refreshed rather than left as evergreen “from” prices. The comparison does not use Product or AggregateRating markup because LinkSpeed is not claiming a universal stock price or publishing genuine customer star ratings on this page.
Who reviews this page: the LinkSpeed Editorial Team maintains the comparison framework and checked-date policy. Deal examples remain tied to their visible provider-source dates rather than being presented as permanently current.

Lowest-bill route for eligible households
Looking for the absolute cheapest option? Check social tariffs first
If the priority is the lowest broadband bill rather than a particular commercial package, a social tariff can undercut mainstream deals. Ofcom's current list, updated 17 August 2026, shows social-tariff prices from £10 to £24 per month.
Eligibility varies by provider. If you or someone in the household receives Universal Credit, Ofcom says you could switch to any of the listed social tariffs available to the address. Major providers also accept several other benefits, including Pension Credit, Employment and Support Allowance, Jobseeker's Allowance and Income Support, with some providers accepting additional benefits.
For an eligible household, this can be cheaper than chasing a promotional commercial tariff. Treat eligibility and address availability as the first checks.
Ofcom says the price should not rise during the social-tariff contract.
Ofcom says customers should not pay an early-exit fee to leave a social tariff.
Most listed tariffs offer more than 30 Mbps, but the exact speed and network technology depend on provider and address.
Full-fibre note: a social tariff is a pricing category, not a guarantee of FTTP. Check the technology and speed available at the exact address before ordering.
