Switching to British Gas

To make your life easier, we've made the whole switching process as simple as possible. This handy step-by-step guide explains what happens next. We look forward to helping you look after your home.

Step 1: Weeks 1-2
Your contract letter/e-mail will confirm your tariff, current rates and payment choice. We'll also contact your old supplier to let them know you're switching to us.

Step 2: Weeks 2-4
If we haven't already contacted you by phone, we'll write to confirm the date we can start to supply your energy. This may be delayed if you have an outstanding bill with your old supplier. (See FAQs below).

Step 3: Weeks 4-6
If you have a credit meter
We'll ask you to send us a meter reading by phone or online. This is important to make sure you only pay for the energy you use.

Step 4: Weeks 4-6
If you have a pay as you go meter
Your free meter key or card will be sent to you along with a guide to your meter. You'll need to activate your key or card when we start to supply you.

Step 5: Weeks 7-8
When we start to supply your energy, we'll write to let you know you're up and running. We'll also give you your account number. You'll need this to hand whenever you talk to us.
