Energy Bills Guide

Energy bills are one of the biggest household costs — and one of the most confusing. This guide explains how the price cap works, what help is available, and practical steps to reduce your bills today.

The Ofgem Price Cap

The energy price cap limits the unit rates and standing charges that suppliers can charge per unit of gas and electricity. It's set quarterly by Ofgem and applies to customers on standard variable tariffs (which is most people).

The cap is based on a typical household using 11,500 kWh of gas and 2,700 kWh of electricity annually. If you use more, you pay more — if you use less, you pay less. It caps the rate, not your total bill.

Check the current cap rate and your rights at Ofgem.gov.uk.

Help Available Right Now

Warm Home Discount

A one-off £150 discount off your electricity bill, paid automatically if you qualify. You qualify if you receive the Guarantee Credit element of Pension Credit. Broader eligibility (low-income households) is assessed by your energy supplier using DWP data — you may be automatically enrolled or need to apply.

• Applies between October and March each year
• Check eligibility with your energy supplier directly

Winter Fuel Payment

A tax-free annual payment to help older people with heating costs. Since 2024, this is now means-tested — you must receive Pension Credit or certain other benefits to qualify. Check eligibility at GOV.UK.

Cold Weather Payment

£25 for each 7-day period of very cold weather (average temperature at or below 0°C) if you receive certain benefits including Universal Credit, Pension Credit, or Income Support. Payments are automatic — you don't need to apply.

Energy Company Obligation (ECO4)

A government scheme where energy companies fund insulation and heating upgrades for low-income and vulnerable households. You may qualify if you rent or own your home, have low income, or receive certain benefits. Apply through your energy supplier or the GOV.UK ECO4 page.

Energy Supplier Hardship Funds

Most major energy suppliers have hardship or customer support funds for customers struggling to pay. Contact your supplier directly and ask about:

• Debt repayment plans (they must offer a realistic repayment plan)
• Hardship grants (some suppliers offer one-off payments to clear arrears)
• Priority Services Register — if you're elderly, disabled, or have young children, register for extra protections including advance notice before any disconnection

Suppliers cannot disconnect you between October and March if you are of pension age or have a disability. If threatened with disconnection, contact Citizens Advice immediately.

Practical Ways to Reduce Your Bills

• Get a smart meter — free from your supplier, shows real-time usage and stops estimated billing
• Submit meter readings if you don't have a smart meter — prevents over/under-billing
• Reduce your thermostat by 1°C — saves around 10% on heating bills
• Switch off standby — devices on standby can add £55-£80/year to your bill
• Full loads only — washing machines and dishwashers are more efficient when full
• Wash at 30°C instead of 40°C — uses around 40% less energy
• LED bulbs — use 75% less energy than incandescent bulbs and last much longer
• Draught-proof your home — cheap draught excluders can make a real difference
• Bleed your radiators — trapped air makes them less efficient

Switching Suppliers

The cheapest fixed tariffs are often not from the big suppliers. Use price comparison sites to find better deals — switching is free and usually takes around 3 weeks:
