This offer is valid until 30th April 2015 and is available for domestic properties only. It excludes warm air units and the simplicity boiler range. We will take 20% off your new boiler at the point of sale, on the basis that we install the boiler, so you'll only need to pay the VAT on the installation any additional work and parts needed. You can't use this offer with another British Gas offer unless the other offer states that it's ok.
 Availability of credit is subject to status, affordability assessment and credit checks.
