About BOXT

Founded in 2017, BOXT is a UK-based website that offers home installation services, including boiler and air conditioning installation as well as electric vehicle charging and smart home solutions. Customers are quoted a fixed price with no extra costs hidden away and most installations can be booked the next day. BOXT works with well-known brands like Worcester Bosch, Vaillant and Google Nest. All engineers are Gas Safe registered or certified electricians. Since launch, more than 300,000 installations have been completed and we have an average Trustpilot rating of 4.9 out of 5 from over 40,000 reviews, making BOXT a trusted service for home upgrades.


How Do I Apply a BOXT Discount Code During Checkout to Save on My Order?

  1. Choose a product and head to the checkout: Head over to boxt.co.uk and select a product, such as a Worcester Bosch combi boiler or an EV charger. Hit 'Get a Quote' depending on the product you have selected. Complete the product configuration and installation options, then click 'Continue to Checkout' to the next step.
  2. Enter delivery and installation information: Input your address and installation choices. Once done, click 'Continue' to move to the payment stage.
  3. Add your discount code: Head to the 'Payment' page and scroll to the 'Promo Code' section just above the payment method options. Paste your BOXT coupon code from DontPayFull in the box and click 'Apply' to apply the code. The new total should appear immediately if the code is valid.
  4. Check and place your order: Choose your payment method and click 'Pay Now' to complete the purchase. BOXT currently does not have a loyalty scheme or stackable discounts.

What should I do if my BOXT discount code is not working?

  • Verify your postcode: Deals apply to certain areas in the UK. Paste your postcode into the product page or checkout to check if the offer is applicable in your area.
  • Double check the boiler type restrictions: Codes are applicable to certain models or brands. For instance, a 10% code will only be compatible with Worcester Bosch systems and not others.
  • Check for installation dates: You will need to book installation within a certain time frame, such as within 14 days. The codes may be invalid if the date you have chosen is outside of this period.
  • Don't combine with finance: Deals exclude interest free or pay monthly options. If you chose a financing method, remove it and reapply the code.
