Broadband Bill Calculator UK 2026
This broadband bill calculator estimates what you’re likely paying for ADSL, fibre or full fibre, and shows the saving from switching if you’re out of contract. The average UK broadband bill is about £31 a month — but out-of-contract prices creep well above that. Use the broadband bill calculator below to see your gap.
How to cut your broadband bill
The single biggest lever is your contract status: if you’re out of contract you’re almost certainly overpaying. Check your end date, then compare new-customer deals for the same speed. Haggling with your current provider’s retentions team also works — quote a rival’s price.
Full fibre (FTTP) now reaches over 80% of UK homes and is often cheaper per megabit than old copper packages.
How much does broadband cost in the UK in 2026?
The average UK household broadband bill in 2026 is about £31 a month, according to the Ofcom Pricing and Consumer Engagement Report. That headline figure hides a wide spread: a basic ADSL line can still be found for around £25, standard and full fibre cluster around the £31 average, and cable or 5G packages run to £33-35 before any premium gigabit tier. This broadband bill calculator uses those real 2026 tariffs so your own estimate reflects the connection type and speed you actually buy.
The biggest hidden cost is not the deal you sign — it is what happens when it ends. Once your fixed term expires you roll onto an out-of-contract rate that averages around £38 a month, roughly £7more than a fresh new-customer deal. Millions of households quietly pay this “loyalty penalty” for years, so the single most valuable habit is to diary your contract end date and switch or renegotiate the moment it lapses.
Broadband is only one of five core household bills. To see it alongside gas, electricity, water and council tax, start with the household bills calculator on the homepage, then compare your energy supply with the gas and electric bill calculator. If you share a home, the split household bills calculator divides broadband and every other bill fairly between housemates.
Coverage keeps improving. As of January 2026, full fibre (FTTP) reached 82% of UK premises, and the average measured download speed is now around 285 Mbps. The old copper network is on its way out: Openreach retires the analogue PSTN on 31 January 2027, migrating all copper-based ADSL and traditional landlines to digital.

Broadband connection types, speeds and typical prices
Not all broadband is the same. The technology carrying your connection sets both the speed you can reach and, broadly, the price you pay. The table below compares the main connection types available across the UK in 2026 — from legacy ADSL to full fibre and 5G fixed wireless — with a typical monthly price for each, so you can see what a fair broadband deal looks like for the speed you need.
| Connection type | Typical speed | Technology | Typical price | Availability |
|---|---|---|---|---|
| ADSL | Up to 11 Mbps | Copper phone lines | £25/mo | Being phased out by Jan 2027 |
| FTTC (fibre to cabinet) | Up to 36-80 Mbps | Fibre to cabinet + copper | £31/mo | Most common 2026 |
| FTTP (full fibre) | 100-1000+ Mbps | Full fibre to the home | £31/mo | 82% of UK premises |
| Cable | 108-1000+ Mbps | Virgin Media O2 network | £33/mo | ~50% of UK |
| 5G fixed wireless | 50-300 Mbps | Wireless connection | £35/mo | Selected areas |

ADSL runs over the old copper telephone network and tops out around 11 Mbps — fine for one or two light users, but being retired with the PSTN switch-off. FTTC (fibre to the cabinet) uses fibre to the street cabinet and copper for the last stretch, so speeds fall with distance. FTTP (full fibre) runs fibre all the way to the home for the fastest, most reliable service. Cable on the Virgin Media O2 network and 5G fixed wireless are the main alternatives to the Openreach network. Because broadband and your energy connection are both fixed monthly costs, it is worth reviewing this against your electricity bill calculator figure when you budget for the year.
Current broadband market rates 2026
To benchmark your own bill, the table below lists verified new-customer rates from the major suppliers, checked in May 2026. Prices exclude promotional offers and TV or phone bundles, and the final column shows the pounds-and-pence in-contract rise scheduled for 2027 — a genuine part of the cost you should factor in before you commit to any full fibre deal.
| Supplier | Tariff | Speed | Monthly | 2027 rise |
|---|---|---|---|---|
| Sky | Full Fibre 150 | 150 Mbps | £22.00 | +£3.00 |
| Vodafone | Full Fibre 150 | 150 Mbps | £23.00 | +£3.50 |

Out of contract vs new-customer deals
The gap between what new customers pay and what out-of-contract customers pay is the biggest saving hiding in your broadband bill. New-customer full fibre deals routinely start at £22-24 a month, while an out-of-contract rate averages around £38 — and creeps higher with each annual rise you never actively agreed to. Left unchecked, that is £192 or more a year over the cheapest fresh deal for the same line.
This is why switching pays. Households that move at the end of their contract typically save between £180 and £292a year versus rolling on. You do not always have to leave: if you call the retentions or “loyalty” team of your current provider and quote a cheaper competitor deal, many will match or beat it to keep you. Either way, the trigger is the same — never let the contract lapse quietly onto the standard rate. GOV.UK collates official consumer guidance on getting a fair deal at GOV.UK.
Out-of-contract broadband is a “loyalty penalty” in the same family as council tax you never challenge or an energy tariff you never review. Once you have sorted your broadband deal, it is worth checking whether you are overpaying elsewhere too — for example with the council tax calculator and the water bill calculator.
Mid-contract price rises: the end of CPI+3.9%
For years, most broadband contracts included an annual mid-contract rise pegged to inflation plus a fixed margin — the notorious CPI+3.9% formula — which meant customers signed up without knowing what they would actually pay. Since 17 January 2025, Ofcom has banned inflation-linked or percentage-based mid-contract price rises in new contracts. Providers must now state any in-contract increase in pounds and pence upfront, before you sign.
In practice, that means a flat £3-4 a month is added each spring rather than an unpredictable percentage. For a typical £31 broadband bill, a mid-contract rise adds roughly £36-48 a year. Pre-2025 contracts may still be on legacy CPI+3.9% terms, so it is worth checking your paperwork. The table below shows the pounds-and-pence rises applied to current contracts in 2026.
| Provider | Monthly increase | Date | Notes |
|---|---|---|---|
| BT, EE, Plusnet | +£4.00 | March 2026 | Openreach group brands |
| Virgin Media | +£4.00 | April 2026 | Cable network |
| Sky | +£3.00 | April 2026 | 30-day penalty-free exit window |
| Vodafone | +£3.50 | April 2026 | — |
| TalkTalk | +£3.50 | April 2026 | — |
| NOW Broadband | +£3.00 | Held April 2026 | — |
Social tariffs for low-income households
If your household receives means-tested benefits, you may be able to cut your broadband bill roughly in half with a social tariff. These are cheaper packages — typically £12.50-24 a month against the £31average — offered to people on Universal Credit, Pension Credit, Employment and Support Allowance, Jobseeker’s Allowance, Income Support, Housing Benefit or Child Tax Credit. There are no exit fees to move onto one, and no price rises during the term on most of them.
The scandal is the take-up. Around 4.2 million households qualify for a social tariff, but only about 5% actually claim one — leaving hundreds of pounds a year on the table per household. You usually apply directly with the provider, who verifies your benefit status, and you can switch to a social tariff even if you are mid-contract with the same company. The table below shows a selection of leading deals.
| Provider | Tariff | Monthly | Speed | Availability |
|---|---|---|---|---|
| Community Fibre | Essential 35 | £12.50 | 35 Mbps | London |
| Virgin Media | Essential | £12.50 | 15 Mbps | National |
| 4th Utility | Social tariff | £13.99 | 30 Mbps | Regional |
| BT | Home Essentials | £15.00 | 36 Mbps | National |
| Hyperoptic | Fair Fibre 50 | £15.00 | 50 Mbps | Urban |
| Vodafone | Fibre 2 Essentials | £20.00 | 73 Mbps | National |
| Sky | Broadband Basics | £20.00 | 36 Mbps | National |
| BT | Home Essentials Fibre 2 | £24.00 | 67 Mbps | National |

How to switch your broadband provider
Switching broadband is far simpler than it used to be, thanks to One Touch Switch (OTS). If you are moving between providers that both use the Openreach network — BT, Sky, TalkTalk, Plusnet and most others — your new provider now handles the entire switch. You place one order, and it completes in about one business day with minimal disruption and no need to contact your old provider at all.
Switching to or from a different network
Moving to or from Virgin Media, a community fibre provider, or a mobile network sits outside One Touch Switch, so you coordinate it manually. Give 30 days’ notice to your current provider and book installation with the new one, timing the two so you avoid a gap in service. Always confirm your contract end date first.
Exit fees and the best time to switch
If you leave before your contract ends, an early-termination fee usually applies — typically the value of the remaining monthly payments. The best time to switch is at the end of your contract, when there are no fees; you can also move penalty-free during a price-rise window if your provider offers one (Sky Broadband gives a 30-day exit on price-rise notification). Check speed and availability at your postcode with the free Ofcom checker before you order, and read Ofcom’s switching guidance if you hit problems.
- Diary your contract end date and switch or renegotiate the moment it lapses.
- Use One Touch Switch between Openreach providers — one order, done in a day.
- Call retentions and quote a cheaper competitor deal before you leave.
- Check for a social tariff if you receive means-tested benefits.
- Avoid paying for gigabit speeds your household never uses.
