What people are saying about us

Excellent customer service! I used 3 times in last 2 weeks, every single time estimate received within 1 hour (!- thanks Stephen:), delivery arranged within 2-3 days, not to mention that price are more than competitive (on popular render board I got 50% discount on price in compare with my usual supplier and internet's offers)! I wish I knew them earlier, but fortunately now I got my perfect insulation supplier and definitely will continue the cooperation.


Verified Buyer

Ordered a particular brand of insulation which happened to be of shortage in the UK at the time. I received an email and a follow up call from a very helpful customer services agent to advise of the nationwide shortage and an offer of an alternative product of similar quality. The original delivery date wasn't compromised but the alternative actually arrived earlier than expected. To our surprise, the alternative delivery was actually a more superior product to the originally ordered product according to our builder. We are clearly very pleased customers!

Great service from Stephen for all his hard work to get my material out to me in a speedy fashion. Stephen was able to get me my insulation in 3 days where every other company was quoting me 3 - 4 weeks. Great service and would recommend to anyone.

Insulation4less product range was very good, they held stock of a recently discontinued item so I was able to finish my renovations with the same insulated plasterboard I'd used throughout my house. Delivery was very quick, I live in rural southwest Scotland and usually have to wait a week or more for pallet deliveries but the delivery came in 3 days. Communication was good with an email 24hrs before delivery. One thing to note - if taking multiple pallet deliveries you really do need a forklift but my driver was happy to split my single pallet down and unload it with me.
