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 Much Should Energy Cost in the UK?

Based on Ofgem's typical-use figures, the average UK household currently pays around £141 per month for dual-fuel energy. Your fair cost depends on your property and the number of people living in it.

Property	Occupants	Fair monthly	Fair annual
1-bed flat	1	£70	£840
2-bed flat	2	£84	£1,008
Terraced	2–3	£120	£1,440
Semi-detached	3	£141	£1,692
Semi-detached	4+	£169	£2,028
Detached	3	£183	£2,196
Detached	4+	£220	£2,640

If your bill is more than 10% above the figure for your property type, you're likely overpaying and could switch to a cheaper tariff.
