UK Bills Benchmark

Are you overpaying on broadband, energy and mobile?

Most UK households quietly overpay on their core bills — not because they chose a bad deal, but because they signed a good one that has since expired. Introductory broadband prices jump at the end of the minimum term, energy tariffs roll onto the variable price cap, and a handset contract keeps charging full price long after the phone is paid off. The result is hundreds of pounds a year leaking out of the typical household budget. This benchmark helps you spot that leak in under a minute by comparing what you actually pay against realistic UK averages.

The seed averages we compare against

To be useful from the very first visit, the tool ships with seeded, illustrative monthly figures based on published Ofcom and Ofgem data and widely advertised market prices: home broadband around £30 a month, a SIM-only mobile plan around £15 a month, and dual-fuel energy around £140 a month for a typical-use household on the Ofgem price cap (roughly £1,700 a year). These are starting benchmarks, not quotes. Energy in particular moves with each price-cap period and with how much gas and electricity you use, so treat the energy figure as a typical-usage reference rather than a personal bill.

How the saving is worked out

For each bill you enter, we compare your monthly price to the average for your region and calculate the percentage difference. If you pay more than the average you see a warning badge; if you pay less, a "good deal" badge. We then estimate two annual savings: the gap to the UK average, and the larger gap to a competitive "best" figure — the kind of price available to switchers and hagglers (around £25 broadband, £9 SIM-only, and a keen energy fix). The headline adds these up into a single "you could save around £X a year" number so you can see the total prize at a glance.

A worked example

Say you pay £38 for broadband, £22 for mobile and £165 for energy — £225 a month, or £2,700 a year. Against the averages (£30 / £15 / £140 = £185) that is £40 a month over, or roughly £480 a year. Against competitive switcher prices (around £25 / £9 / £125) the gap widens to about £66 a month, or nearly £800 a year. Even capturing half of that by switching one or two services is a meaningful, repeatable saving — and unlike a one-off cashback, it lands every single month.

Why contract-end dates matter most

The single biggest driver of overpaying is timing. Providers rely on customers forgetting when their deal ends, because the moment it does you usually roll onto a higher out-of-contract price automatically. The fix is simple: switch or haggle in the 30-day window before your contract ends, when you are free to leave without exit fees and have the most negotiating leverage. That is exactly what the reminder feature is for. Add your contract-end date and download a calendar (.ics) file, or leave your email, and you will be nudged 30 days before — turning a vague intention into a dated action.

Switching versus haggling

You do not always have to leave. A retention call quoting a cheaper competitor often unlocks a loyalty discount, especially on broadband and mobile. For energy, the choice is between a fixed tariff (price certainty) and the variable price cap (which can fall as well as rise). The right move depends on where the cap is heading, your usage, and any exit fees — so always check the specific terms before you commit. The point of this tool is not to tell you which provider to pick, but to show you clearly when you are paying over the odds and when it is worth acting.

Honest caveats

These averages are illustrative and update over time as users anonymously add their real bills, so the more people contribute, the sharper the regional and by-provider picture becomes. Your own best deal depends on your address, line speed, data needs, energy usage and credit profile. Always read your contract's exit fees and the full terms of any new deal before switching. This is a comparison tool to help you ask better questions — it is not financial advice.
