If you are able to get into your loft and roll out some insulation yourself I would avoid this company. We had SIG/ miller pattison energy management based in ivybridge come to do ours. It was free through a government based scheme. We really wish we never bothered. The first person for the inspection turned up half an hour after the latest time and noone even bothered to call. On the first appointment for the loft insultation they never turned up and didn't contact us, on the second appointment they again didn't turn up. On the third appointment that had been booked for a fixed time because we had been messed around so much they turned up half an hour late. The woman we spoke to in the office said oh they had to speak to a supervisor that's why they are late (like that is our problem!), the man then turned up and was extremely rude, when I asked how long it would take because they were supposed to be here at 8 and I had to leave for work I was told 45 minutes longer than I had previously been told. When he said he was called back I said that's not really my problem I've been waiting here since 8 and this is the 4th appointment people have either not turned up or have arrived late. His response to that it was that it was not his problem. He was extremely rude and made a woman in her house on her own feel very uncomfortable letting them in. He said that he could check how long it would take and then walked off shouting actually I won't bother. I assume it was only because of his more pleasant and polite younger (got the impression more junior) colleague that he returned. I really wish we went to wickes and bought one roll getting 4 free. It would have saved us taking 4 days off work which has actually cost us a lot more than the £10 it would have cost at wickes.
