No, there is no limit!

You’ll earn £300 cashback for every three Baxi 600 or Baxi 800 boilers that you install and register on Baxi Works.

We’ll aim to pay you within 21 days of the end of the promotion, but please allow until the 21st February 2027. We will process a BACS transfer into your nominated bank account for your total cashback amount, subject to you completing your bank details, as below and in accordance with our terms and conditions.
