Payment options to suit you
You can pay for your boiler in full with major debit and credit cards or by cheque.
Once you agree to an installation, we’ll usually take a 10% deposit. The full amount is only paid once your new boiler is up and running.
We can arrange a monthly finance agreement with Barclays Partner Finance, meaning you can choose to spread the cost of your new boiler over three to ten years.
- 12.5% representative APR.
- No upfront deposit required.
- Make additional payments at any time.
