Pressure switching, inferior replacements, slow, inaccurate
Update 2: "our accounts department issued the remaining refund straight away". Email sent
Sep 24, 2024, 5:46 PM advising of error. Email from Paypal Oct 1, 2024, 9:37 AM "Your refund of £60.00 GBP from Insulation4Less Ltd Your refund is on the way! Available in your card by 3 October 2024", received. This sums up the transparency and quality of service - 4 working days is not 'immediately.
Update: the refund amount, provided days later and after much chasing was short by approximately £60 - easy to spot as Paypal shows original payment and what was refunded, so hard to believe this was a genuine mistake - it's not like it was part of an order being delivered, it was the whole order.
A company worth avoiding! The day before my order was due for delivery, received a text message, email, and phone call all within a minute of one another; the caller claimed they couldn't get the Celotex insulation I ordered, but they could substitute another of similar performance - I had to make a decision urgently otherwise it wouldn't go out on time. I didn't order Celotex, but I had ordered Mannok. I specifically asked about the fire performance of E, to which the caller confirmed it was the same. I refused to give an immediate answer, and insisted on reading the data sheet of the substitute product first (which they had sent in the email). Within less than a minute, I noted the fire class was worse than what I ordered, so I tried to call back. There are no direct dial numbers for people, so I spoke to a generic person who spoke privately to the previous caller - and then reported she had already spoken to me. I had to insist on either speaking directly or they could cancel the order. Five minutes later I had a call back from the original caller, and received a slightly patronising and entirely unconvincing story about how they are sort of the same and one is hard to get further north. Needless to say, order cancelled.

Was told they would call to book…
Was told they would call to book delivery, no phone call. The once booked on a random day when I'm not in, I request it was moved to only be completely ignored. When I complained they did nothing... just ignoring the fact I now have good left dumped on a driveway... very poor
Your reply is also incorrect and false, I have sent several emails in reply confirming I wasn't home and that they were left on the driveway, I suggest you revisit your inbox....
Yes again, completely incorrect! You’ve even replied to one of my emails….

What a shambles. Never again.
Ordered 1700 pounds worth of insulation. The 1st of many orders for a house build. Did not hear anything for six days. Chased. Told what I had ordered was not in stock and you can't get a lorry to my postcode. After numerous phone calls agreed for an alternative product to be delivered to a layby down the road from me as I was desperate. Agreed a delivery date, the night before was sent an email saying that part of it can't be delivered and then the email stated that part of what was going to be delivered was not what I had ordered in the first place. The SIG lorry turned up and agreed to drop it off at neighbour close to the main road. On pulling back the curtain we realised the next drop had not been strapped in properly and had collapsed all over our load. This resulted in another half hour of wasted time. The driver did however do us a favour by not bothering to raise the air suspension and leaving a large gouge across the road with the underun bar and Moffett. This has proved to be useful reminding us on a daily basis never to use this company again. We were offered extra discount on the next orders but quite frankly if it was half price I probably wouldn't bother. The most annoying part is that this company takes orders by its website but then does not tell you that they cannot supply what you want. As a contrast the contractors suggested using jewsons. They actually virtually priced matched and what I wanted was there the following afternoon delivered to my address by an 18 tonne lorry. No doubt the reply to this will be the usual we have thousands of happy customers etc etc but to take an order that you can't fulfill and not contact the customer is unforgivable.

Celotex insulation from Insulation4less not fit for purpose.
I bought some Celotex insulation from Insulation4less & every sheet was deformed along the edges. The edges were concave which meant they would not butt up to each other effectively making their insulation properties ineffective. I contacted Insulation4less several times by email but received no reply. I suspect they are selling reject products. I will not be using them or Celotex again.
