About Insulation Superstore

Established in 2008, Insulation Superstore is a UK-based retailer of insulation products for both residential and commercial projects. They hold thousands of products from a range of brands including Celotex, Kingspan, and Rockwool, and offer insulation solutions for lofts, walls, floors, roofs, and acoustic insulation. Product information and datasheets are available on the website to help customers make a confident purchase. Any orders over £300 are eligible for free delivery to mainland UK. With bulk and trade prices, Insulation Superstore can help both DIY enthusiasts and professional installers find quality insulation materials at an affordable price.

How Do I Use a Promo Code at Checkout on Insulation Superstore?

  1. Add product to basket: Add a product such as Celotex GA4000 PIR Insulation Board from the product range. Tweak the size and amount needed then click the orange 'Add to basket' button to the right of the product page.
  2. View your basket: Click the 'Basket' icon in the top right hand corner of the page and click the blue 'Checkout Securely' button underneath the order summary.
  3. Enter promo code: On your 'Your Details' page during the checkout process, scroll down and look for the 'Add a discount code' section. Paste your coupon code from DontPayFull into the box below this section and click the grey 'Apply' button to apply the code. A success message and updated total will be displayed if the code is valid.
  4. Complete checkout: After entering your delivery details, click 'Continue' and then 'Place Order and Pay' to apply the code.

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

  • Verify vat inclusion: Codes work on net prices only. If your basket total is VAT inclusive, the code will not apply as it would for a non-VAT basket. Calculate your total without VAT again.
  • Check product exclusions: Codes exclude trade, or bulk pricing products. If you have items in your order that are of a trade-only nature, remove them and try the code again.
  • Account type restrictions: Terms apply only to trade or public accounts. Log out and re-enter as a guest, or change account type if you can.
  • Apply partial basket split: If the basket gets in the way of the code, split the basket. Apply the code to suitable items and then place a second order for everything else. This way you still get the promotion.

Insulation Superstore Coupon and Discount Code FAQ: How to Save More

What are the best ways to save on Insulation Superstore?

With bulk pricing, you can use a promo code together with the savings on delivery. You can get free delivery on orders over £300, which can save you up to £50 if you are ordering large or heavy items.

Do Insulation Superstore provide quantity discounts?

Absolutely, a lot of items have tiered pricing. For instance, when you buy 20 or more insulation boards in one order, you could save up to 12% per unit.

How often do new Insulation Superstore discount codes come out?

Codes come out monthly, with seasonal spikes in March, July, and November based on past data. We check our hand-tested codes on DontPayFull as they go live.

Are there any trade discounts available?

Yes, trade account holders receive special pricing that is not available to non-account holders. Savings can range from 5% to 15% depending on the product type and order quantity.

Can you save when you buy full pallets?

Purchasing full pallets usually means lower prices per board because you're getting a better deal per item. For instance, a full pallet of Celotex GA4000 insulation boards costs approximately 8% less per board than buying the same amount separately.

Does the site have a price match guarantee?

No, they do not currently have a price match guarantee. Your best bet is to apply any verified promo codes and bulk pricing to save money.

Are there any seasonal sales events with bigger discounts?

Yes, there are larger discounts during end of season clearances late February and late August. The savings you can get during these times can be up to 20% off selected insulation products.

Is there any discount with the newsletter?

Yes, when you sign up to the newsletter, you can get promotional offers and the occasional code here first. These codes typically provide 5%-10% off selected brands or categories.
