About Castle Heaters

Established in 2011, Castle Heaters is a UK-based marketplace for electric heating solutions for both residential and commercial customers. They sell a variety of infrared heaters, towel rails and panel heaters which are designed for efficiency and ease of use. Products are backed by warranties between 1 to 5 years and many have programmable digital thermostats for accurate temperature control. Product specifications and guides are available on their online store at castleheaters.co.uk, which can help you find the best heater for you. Free UK delivery is available on orders over £50, and most items can be dispatched within 1 to 2 working days. You can also contact customer service by phone or email during standard UK business hours.

How Do I Apply a Castle Heaters Discount Code During Checkout?

  1. Choose heater product: Head to any product category like 'Far Infrared Heaters' and select a model such as the 'Premium Infrared Heating Panel 580W'. Click 'Add to Cart'.
  2. Shop cart: Once the item is added, click the shopping basket icon in the top right corner. Then click 'View Cart' from the dropdown and navigate to the cart page.
  3. Paste in the promo code: Once in the cart, find the 'Discount code' box underneath the items in your basket. Enter your Castle Heaters coupon code from DontPayFull and click the 'Apply Coupon' button next to it.
  4. Continue to checkout: Once the coupon is applied and the savings appear, click the 'Proceed to Checkout' button in the bottom right of the cart page to continue to billing and shipping.

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

  • Verify bundle restrictions: Some codes do not work with heater bundles that have a discount applied. If you are purchasing a package deal, take the package deal out and use the code on individual items.
  • Check out the seasonal code limits: They often have winter or Black Friday codes which are only valid for a short time. If your code says 'expired', check the dates - some offers only last 48 hours.
  • Use a different browser: The checkout page may not load on certain mobile browsers. Sign in with Chrome or Firefox and paste the code in.
  • Stacking not allowed: They disallow the combination of codes with newsletter signup offers. So, if you applied the 10% welcome discount, go back and remove that code and test the other code separately.
