Buy a qualifying oil boiler – any Grant, Navien, Warmflow or Worcester, and we’ll send you a voucher by email at the end of the month for you to spend on any tool in our Trade Only Tools catalogue. Check out the Terms and Conditions here.

At the end of each month, all qualifying purchases from that month will be redeemed by a single code sent to the primary email address registered to the account. Promotional discount codes are valid for 28 days from the date of issue, for one single purchase only, and are not transferable. If the purchase value is less than the value of the code, the remaining balance cannot be redeemed in any other way, and will be voided.
