Why Switching Saves Money

Millions of UK households are still on their supplier’s standard variable tariff — almost always the most expensive option. Switching to a competitive fixed deal takes minutes and can save £200–£400 a year. The process is handled almost entirely by your new supplier, so there is very little for you to do.

What You Need Before You Start

• Your annual electricity or gas usage in kWh (on your bill)
• Your postcode
• Your current unit rate and standing charge

Step 1: Compare Deals

Enter your postcode and usage into a comparison tool. You will see a ranked list of deals with estimated annual costs. Focus on the total annual cost rather than just the unit rate — a low unit rate paired with a high standing charge can end up costing more overall. If you want to cut your energy bills today, it only takes a few minutes.

Fixed vs Variable Tariffs

Fixed tariffs lock in your unit rate for 12 or 24 months, protecting you from price rises. Variable tariffs track the market and can go up or down. In uncertain markets, a fixed deal gives you certainty and peace of mind.

Step 2: Choose and Apply

Select your preferred deal and complete the short application — usually just your name, address, meter details, and bank information for direct debit. The whole process takes around five minutes online. You can also energy saving advice to see what’s available.

Step 3: Sit Back

Your new supplier notifies your old one and manages the switch. You have a 14-day cooling-off period to change your mind. There is no interruption to your supply — the same pipes and cables deliver your energy throughout.

Step 4: Final Bill

Your old supplier sends a final bill based on your closing meter reading. If you have a credit balance, they must refund it within 10 working days. Submit an accurate reading on switch day to avoid any disputes.

How Often Should You Switch?

At minimum, review the market when your fixed tariff ends — typically every 12 months. Set a reminder six weeks before your deal expires to give yourself time to compare and switch before dropping onto the expensive default rate.

Compare available deals now and see exactly how much you could save. The switch takes five minutes — the savings last all year.
