How do I use my Blue Light & Defence Forces Discount?

To claim your Blue Light or Defence Forces discount you need to: 

  1. Log into your Blue Light account or Defence Services account and search for the BOXT promotions page to find the discount code.
    (You can register for a Blue Light Card here or for Defence Services membership here, if you don't have an account already.) 

  2. Enter the discount code at step 5 of the checkout process under 'Got a discount code?' and click 'Apply'. 


  3. Complete your purchase by entering your payment details

  4. Unless otherwise stated, the discount will be £60 off the full price of a new boiler or air conditioning unit installation, and cannot be used in conjunction with any other offer or promotion. 

Please note: Discounts are not valid on Electric vehicle charger installations or our Home Cover plans and you may only apply one discount code to your order.
