If you've never switched energy supplier — or haven't checked your tariff in over a year — you're almost certainly paying more than you need to. With the UK energy price cap still affecting millions and fixed deals returning to competitive territory, now is the time to act. Switching is free, takes 15 minutes, and could save you £200-£500 a year.
Why You Need to Switch
Most UK households are on their supplier's default or standard variable tariff (SVT) — which is almost always the most expensive option. Even if you switched before, your fixed deal has likely ended and you've been rolled onto the SVT without realising.
- Price cap ≠ price guarantee: the cap sets a maximum, not a minimum — you can find cheaper
- SVTs are lazy money: suppliers rely on inertia to keep you overpaying
- Fixed deals are back: after the 2022-2024 energy crisis, competitive fixed tariffs have returned
- Switching is protected by Ofgem — your supply is never interrupted
How to Compare Tariffs
You'll need a recent energy bill or your annual consumption in kWh. Then use a comparison site:
- Ofgem-accredited sites: Uswitch, Compare the Market, MoneySupermarket
- Non-commission sites: Energy Helpline, Citizens Advice energy comparison
- Check both gas and electricity: dual fuel deals may be cheaper than separate suppliers
- Look at the annual cost: ignore cashback gimmicks and focus on total yearly spend
- Enter your actual usage for accurate comparisons — don't rely on 'average household' estimates
Fixed vs Variable: Which to Choose
This depends on where energy prices are heading — and your appetite for risk:
- Fixed tariff: locks your unit rate for 12-24 months — protects against price rises
- Variable tariff: rate changes with the market — benefits you if prices fall
- In 2026: if fixed deals are below or near the price cap, locking in makes sense
- Check exit fees: some fixed deals charge £25-£50 per fuel if you leave early
- A good rule: if a fixed deal is 5%+ cheaper than the cap, take it
Step-by-Step: How to Switch
Switching is straightforward and your new supplier handles the entire process:
- Step 1: gather your current tariff name, annual usage (kWh), and postcode
- Step 2: compare deals on Uswitch or similar — filter by fixed rate and no exit fees
- Step 3: choose your new tariff and sign up online (takes 5 minutes)
- Step 4: your new supplier contacts your old one — you don't need to do anything
- Step 5: switch completes within 5 working days (Ofgem's switching guarantee)
- Take a meter reading on switch day for an accurate final bill
Extra Ways to Cut Energy Bills
Switching tariff is the biggest win, but combine it with these for even more savings:
- Smart meter: free from your supplier, helps you track usage in real-time
- LED bulbs: use 75% less energy than old bulbs
- Draught-proofing: £10-£30 in materials, saves £25-£50/year
- Turn thermostat down 1°C: saves roughly £80-£100/year
- Wash at 30°C: uses 40% less energy than 40°C
