npower - Gas & Electricity Energy for your Home

npower Logo

Switch your power supply, choose from a range of simple tariffs and make further savings by earning cashback thanks to our npower deals. As one of Britain's leading energy suppliers, they provide gas and electricity to residential and business accounts. Just enter your postcode to get a quote, set up an online account, arrange to pay by Direct Debit and make use of their handy mobile app.

Check if you are eligible for a free energy efficient boiler or wall and loft insulation, which will save energy and reduce your heating costs, while you can also buy such items as carbon monoxide alarms. Read helpful tips on how to look after boilers and keep them running over the winter, including making sure they are subject to an annual service.

They also offer energy efficiency products such as solar panels and heat pumps, while you can find out more about their Feed-in Tariffs, which will allow you to sell any surplus renewable energy you produce. Npower will be installing smart meters in all of their customers' homes by 2020.

Switching to npower

Switch to npower from any of the other energy companies and they will send you a welcome pack and a copy of your contract within the first five days. This will include a contract number, which you can use to create an online account.

They will contact your current energy supplier and inform them you are switching, but you should check your information as you only have 14 days to change your mind from the day you sign up. Within the following 10 days, they will confirm your start date and ask you to provide a meter reading, which they will send to your existing supplier to enable them to provide you with a final bill.

Npower will take over your energy supply within a further two days and send your first bill within three months. Once you have switched, you can set up a Direct Debit and register for an online account, while you should allow up to eight weeks after you join for any vouchers to arrive.
