Wow, that's great, thanks sonichedgehog! Just to check does laying loft insulation or laying loft boards count as a 'building work' under these regulations? In my case the original updated insulation was done ~5yrs ago by a company organised by previous owner (on a council grant I believe). The loft boards I laid, but only over the middle section of the loft whilst stuffing as much insulation between rafters as I could! Definitely sounds like I've been conned at, or at least very badly misinformed. Everyone beware!

hi all, first time posters, but found this forum by searching 'Miller Pattison cold calling'! I've just had a very similar experience to a lot of the previous posts; a cold call with a 'surveyor' who had a look in my loft, saw there were mainly boards but plenty of excess insulation material at the edges, albeit under a fair few boxes. However they informed me that there is a legal requirement for insulation to be 11" thick, and that I would still need further insulation. I found this rather unlikely, but she was insistent, as was her supervisor who was cavassing the houses opposite. Having got as far as filling out the form, and asking me a series of questions they then phoned through to their office to arrange booking. It was at this stage I explained I didn't want to sign anything, but was very strongly pressured to say they could not accept me keeping the form and signing later after I'd been able to check everything out. I felt extremely pressured, and made very uncomfortable, but did eventually get them to leave without signing anything. Now I've done some searching I'm very glad I did. Does anyone know of ANY legally binding requirment for loft insulation? I've been searching for a while now but no success, other than recommendations of the 280mm (~11") they mentioned.... this all seems very suspicious to me! Thanks everyone for the comments and advice.
