No, you do not need to switch tariffs to get the offer, but you need to have an active British Gas Energy account (variable or fixed) at the time of your boiler installation to receive the bill credit.​

​What happens if I switch energy supplier before the boiler is installed?

If you switch to another energy provider before your boiler is installed, you will not be eligible for the £200 energy credit.

How will the £200 be applied to my account?

Once your boiler is installed and you remain a British Gas energy customer, the £200 will be applied as credit to your energy account within 60 days after your installation and you’ll see it reflected on your next energy bill. Dual fuel customers will receive the credit in one of their accounts (usually the electricity account).​
