Average Utility Bills UK 2026

For 2026 the average UK household spends roughly £430–£480 a month across energy, water, council tax, broadband and mobile. A single person in a flat is nearer £330, while a larger family home can exceed £590. Energy and council tax are the biggest lines.

A single person typically pays around £330 a month all in — about £105 energy, £35 water, £150 council tax at Band D (or 25% less with the single-person discount), £31 broadband and £15 mobile. The single-person council tax discount is the easiest saving to claim.

Energy remains well above pre-2021 levels despite easing from its peak, council tax rose up to the 4.99% cap for 2026-27, and water bills went up 5.4%. Broadband and mobile also rose with inflation-linked mid-contract increases.

Claim every discount you're entitled to (single-person council tax, WaterSure, funded childcare), switch broadband and mobile when out of contract, and check for a fixed energy tariff below the cap. Our calculators show the numbers for your own home.
