Student Energy Bills After the October 2026 Cap Change

Your first student-house energy bill should start on the correct responsibility date, with readings that separate your household’s usage from earlier occupants. Check these before dividing the bill among housemates.

For a typical dual-fuel home paying by Direct Debit, the cap for 1 October to 31 December 2026 is £1,723, or £1,935 on the previous consumption basis. It limits eligible default-tariff rates in Great Britain, not the total your house can spend. Fixed tariffs, Northern Ireland and heat networks need separate checks.

Check opening readings and estimated usage

Match the bill’s start date with the agreed responsibility date. Compare its opening readings with your dated photographs and check which readings are marked estimated.

If you missed the opening or 1 October changeover reading, send a real current reading and any dated evidence you have. Ask the supplier to explain and review the estimated allocation. Do not take a reading now and label it as an earlier one.

A bill spanning the cap change can correctly contain two rate periods. If the supplier allocated too much gas usage to the more expensive period, ask it to review the evidence. An active fixed tariff follows its own rates instead.

If an old balance or incorrect start date blocks progress, use the energy account evidence checklist.

Read rates and charges before comparing the total

The October Direct Debit national averages are 26.32p/kWh for electricity and 7.97p/kWh for gas, with standing charges of 54.83p and 29.68p a day. Your region and payment method can differ.

Standing charges continue when nobody is home. Agree in advance how holidays affect fixed costs and usage shares. A first autumn bill is useful evidence, but it does not establish the house’s annual consumption on its own.

Use the cap guide for the dated rate periods, then compare tariffs using a realistic household usage estimate and contract terms.

Split the bill when responsibility changes

If the same people share the whole period, your agreed equal or weighted split can apply to the total. If someone joins or leaves, establish responsibility dates, separate fixed costs from usage and retain readings where available.

A days-based usage allocation is an estimate, not measured consumption. Make the assumptions clear and keep the shares equal to the bill total. Follow the housemate moving-out checklist before changing supplier accounts, and use the split calculator for the arithmetic.

Check electricity VAT and bills-included terms

Domestic electricity VAT in Great Britain is 0% from 1 October 2026 to 31 March 2027. Domestic electricity in Northern Ireland and domestic gas remain at 5%. The saving is already reflected in the October cap; it is not another discount to subtract.

If you pay a supplier directly, check the VAT line and supply dates. If a landlord separately recharges energy, ask for the underlying charges and appropriate resale guidance. If energy is included in rent, the tax change does not establish an equivalent rent reduction. Read the agreement and any fair-usage conditions. Our electricity VAT guide explains these branches.

Check the tenancy before choosing a long fix

Do not assume every student let has a fixed 12-month term. In England, most covered private assured tenancies became periodic on 1 May 2026. Halls and other arrangements can differ, and Wales, Scotland and Northern Ireland have their own renting rules.

Ask a supplier what happens if you move during a fixed tariff, including transfer options and exit fees. Agree who holds the contract and what housemates will do when somebody leaves. A private bill split does not change what the supplier can collect under its contract.

For a new household, start with the first-renter setup guide, keep your dated evidence and check the bill before settling shares.
