Cheapest UK Home Energy Suppliers After the October 2026 Cap
Understand the impact of the new 2026 price cap on your bills, compare the lowest home energy deals across the UK, and start saving today.
What is the October 2026 Energy Price Cap?
Ofgem's updated price cap, coming into effect in October 2026, aims to protect UK households from excessive energy prices. The cap limits the maximum amount suppliers can charge for standard variable tariffs (SVT)—which most households are on. Knowing how this affects your home energy bills is key to unlocking savings.
- The cap sets a ceiling on unit rates and standing charges for gas and electricity.
- Only applies to domestic (not business) customers on default/variable tariffs.
- Encourages competition between energy suppliers for your benefit.
But even with a cap, some suppliers offer much cheaper home tariffs than others, especially if you compare and switch.

How the Cap Affects Home Energy Costs in 2026
The October 2026 price cap means:
- Unit rates for both gas and electric are restricted, protecting against price surges.
- Standing charges (the daily fee just for having a supply) remain variable, so compare these too.
- Suppliers compete to offer the best value within the cap—often below it for fixed and online deals.
Some smaller and challenger brands may offer introductory discounts or greener tariffs, so check all your options.
How to Get Even Cheaper Home Energy
- Sign up for direct debit for extra discounts.
- Take regular meter readings, or get a free smart meter for accurate bills.
- Combine dual fuel (gas + electric from one supplier) for further savings.
- Use referral or cashback offers when switching.
- Consider greener tariffs if you want 100% renewable energy (can be just as cheap!)
