Is it worth switching energy supplier right now?

It depends on your current tariff versus the best available deals. Use our comparison and 'should I switch?' tools to see whether a fixed or better variable deal would save you money today.

How long does switching energy supplier take?

A switch typically completes within five working days, and there's a 14-day cooling-off period. Your supply is never interrupted — the same gas and electricity flow into your home.

Are there exit fees for switching?

Some fixed tariffs charge exit fees of around £30–£60 per fuel if you leave early. Variable and rolling tariffs usually have none. Always check before switching.

Will switching supplier interrupt my supply?

No. Switching only changes who bills you; the physical gas and electricity supply continues uninterrupted with no work needed at your home.

Should I choose a fixed or variable tariff?

Fixed tariffs lock your unit rates and protect against rises; variable tariffs follow the market and can fall. If prices are expected to drop, variable can win, but it carries more risk.

How to Switch Energy Provider

A step-by-step guide to switching your gas and electricity supplier. It's easier than you think — most switches take just 5 days.

1. Check Your Current Deal

Find your latest energy bill or log into your current provider's account. Note your tariff name, end date, and any exit fees.

Check if you're on a fixed or variable tariff
Note your contract end date — switching before this may incur exit fees
Record your current unit rates and standing charges for comparison

2. Compare Providers

Use our provider comparison table to see the latest prices. Consider total annual cost, not just unit rates.
