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.

What This Means

Ofgem's review of the energy system's resilience during extreme heat is crucial for ensuring supply security as climate change brings more frequent heatwaves. While not directly impacting prices, a more robust system prevents outages and costly emergency measures. We expect this review to lead to recommendations that strengthen our infrastructure, safeguarding against future disruptions that could otherwise lead to significant economic and social costs for consumers.

Consumers: No immediate change to household bills, but worth watching.
Businesses: Limited direct cost impact for businesses for now.
