About WarmZilla

Founded in 2018, WarmZilla is a UK-based website that makes it easy to purchase a new boiler, with fixed prices and next day installation in England, Scotland, and Wales. Here you can compare boilers from top brands including Worcester Bosch, Vaillant, Ideal, and more, with all installations done by Gas Safe registered engineers. WarmZilla offers a free online quote tool that can be completed in under two minutes, and you receive transparent pricing upfront. The boiler installations are covered by up to 12 years manufacturer warranty, with interest-free finance available over 24 months. WarmZilla has installed thousands of boilers, and the focus is on speed, transparency, and ease.


How Do I Apply a WarmZilla Promo Code During Checkout to Get a Discount?

  1. Choose your boiler package: Head to warmzilla.co.uk and click 'Get a Quote' in the middle of the screen. Answer the multiple-choice questions regarding your property and the heating you need. After this, you will be presented with a list of recommended boilers such as Worcester Bosch Greenstar 4000 or Ideal Logic Plus. Click 'Continue with this boiler' to continue.
  2. View your boiler package: On the 'Your Boiler Package' page, you will be able to view the boiler you have selected, the installation information and any extra features. Click 'Continue to Checkout' at the bottom of the summary page to move to the payment stage.
  3. Add your discount code: Head to the 'Checkout' page and scroll down to the 'Order Summary' section on the right-hand side. Underneath the total, you will see the 'Have a promo code?' text. Click on this text link to reveal a text field labelled 'Enter promo code'. A discount code box will appear underneath. Paste your discount code from DontPayFull into this box and click 'Apply'. The discount will update immediately.
  4. Place your order: Enter your personal details, installation address and payment information. Click the 'Place Order' button at the bottom to checkout.

What should I do if my WarmZilla discount code does not work?

  • Verify boiler or service type: Any coupon codes will likely be for a particular type of boiler or service. If you chose a high end or custom package, the code cannot be used.
  • Check postcode eligibility: Some offers are only available in specific areas. See if you can apply a different postcode from a qualifying region to see if you are eligible to any restrictions.
  • Double check the quote page code box entry: All discount codes need to be applied on the quote page before checkout. If this step is missed, the system may not pick up the discount afterwards.
  • Apply manual application for live chat: If the code looks good but doesn't work, get in touch with customer support via live chat. They will be able to check the code and apply the discount manually to your order.
