Customer Reviews
Quick service, good insulation
Ordered acoustic mats. Arrived fast. Product was exactly as expected. Good prices. Will use again.
Good product, delivery could be faster
I ordered some PIR insulation boards for a loft conversion project. The product itself was exactly as described and seems to be of good quality, which was important for the R-value I needed. Prices were competitive, especially considering the bulk discount I received. Delivery took almost a week to reach me in Nottingham, which felt a bit slow. Not a deal-breaker, but something to keep in mind if you're on a tight schedule. Customer service was helpful when I called to check on the delivery status.
Easy and stress-free
Needed some pipe insulation for a small DIY job at home. Found what I needed quickly on their site. Everything went smoothly from clicking purchase to getting it delivered. The package arrived in good condition a few days later, which was great. No fuss, no drama, just got what I ordered. Happy with how simple it was.
Got a decent deal
I was looking to insulate my attic and found their website. I compared prices with a few other places and Insulation4less had pretty good rates, especially with the bulk buy discount they offered for the amount of glass mineral wool I needed. The free delivery over a certain amount really helped with the overall cost too. It felt like I got good value for money, and the order arrived within the estimated timeframe. Definitely worth checking out if you're on a budget.
Fantastic selection, speedy delivery!
I was looking for some specific fire-rated insulation for a tricky spot, and Insulation4less had exactly what I needed! Their range is absolutely incredible, and the product details were super helpful. The ordering process was a breeze, and my order arrived so much faster than I expected. I am genuinely impressed with the quality and the whole experience. I'll definitely be back for my next project!
Reliable for my projects
This isn't my first time ordering from Insulation4less, and they continue to be a reliable source for materials. I've bought loft insulation rolls and some vapour control layers from them before. This time I needed cavity wall insulation, and the process was just as smooth. The website is easy to navigate, and the product descriptions are always accurate. Delivery was on time, just like my previous orders. It's good to know I can count on them for consistent quality and service.

Hey, wondering if anyone knows how long delivery usually takes? Need some PIR boards pretty quick for a project in Manchester.
Thinking of buying a load of loft insulation here, but I usually go to Wickes or B&Q. Are the prices much better here for DIYers?
