Free delivery isn't a standard offering at Insulation Superstore, as they tend to keep delivery charges separate from product pricing. However, on occasion, they might offer free delivery for larger orders or as part of specific promotions, for example, on certain Celotex PIR insulation purchases over a set value. Delivery costs generally depend on the products you're buying and your location in the UK, with additional charges sometimes applying to Scotland, the Scottish Highlands, and the Islands.

If you're a consumer and change your mind about an Insulation Superstore purchase, you generally have 14 days from the day your goods arrive to notify them. You'll need to return the items, typically at your own cost, ensuring they are unused and in their original packaging. Refunds are usually processed within 14 days of them receiving the returned product, or evidence you've sent it back. Be aware that deductions might be made from your refund if the value of the goods has been reduced due to handling beyond what's necessary to inspect them. Some made-to-measure or special order products may not be returnable unless they are faulty.
