Ideally have a recent electricity bill to hand and go to an Ofgem accredited price comparison website such as TheEnergyShop.com. The key bits of information you need will be your supplier, current energy tariff details and if there is any exit fees, payment method e.g. monthly direct debit and your annual electricity consumption in kilowatt hours (kwhs).
A copy of your most recent electricity bill, your bank details (if you're signing up for monthly direct debit) and about 20 minutes of your time. Your electricity bill will enable you to do an accurate energy comparison as it will contain the necessary information such as supplier name, tariff, energy payment method and your annual electricity usage.
£578 according to the latest stats! That's about 46.1% of your annual energy bill for those with both gas and electricity. If you are an electricity only customer i.e. you have electric heaters, cooking facilities etc… then your electricity usage will obviously be higher.
Electricity tariffs & prices are falling at the moment, but you can still save by switching. This is effecting most people through the government's Energy Price Cap which was announced in August as reducing by 6% with effect from 1st October 2019 which will take approximately £75 off the average bill. However, much greater savings are available for those who proactively seek to switch energy suppliers.
Increasing your awareness of your energy consumption is a great place to start to save money. Which appliances use the most electricity? These include hair dryer, microwave, electric oven, security light, any form of electric heater, tumble dryer etc. Knowing which appliance and how much they cost will make you more aware of their use and learn how to maximise energy savings & reduce waste. A great device to help with this is a Home Energy Monitor. They are actually quite good fun too as you run around the house testing appliances out with your jaw on the floor when you see it spike! "Cup of tea anyone!".
