I had these guys over to our house for a quote (then INSISTED on me AND my wife being there - so felt a bit pushy in that way) and the product seems like a good one for super insulating your house and saving money but their sales approach totally killed what seems like a good product. They quoted over £8k for one days work to basically spray "special" foam between all the rafters. But then pressurized us to sign up for it for 20% off there and then without giving us time to decide. Might be a good product, but they are totally unprofessional and pushy when it comes to trying to finally sell it to you. Also, if you are expecting a quick quote, DON'T get these guys around. They will be with you for at least 60-90mins. I would have given more stars for their presentation, as he was quite convincing about the product. But their sales pitch was way too scammy and pressurized. They could have had a customer, but not it that way. Not impressed.
