In response to all these posts, I think I might have some useful help to pass on, as I am working (but not directly employed as we are a marketing company, for which I've only been involved with for a couple of weeks) for Miller Pattison. The details about where the grant comes from are completely accurate. The work involved is as follows. Before they lay the insulation, the do a full MOT of your loft, i.e. ensuring that your loft is 'breathing' as it should. This is done by ensuring that all your soffitts are clear, any tanks you may have are insulated correctly, and anything possibly detrimental to the insulation doing its job is corrected. The insulation is then layed to a depth of 270/280mm. The customer should be provided with a clean energy certificate, which obviously makes the property easier to sell in the future and also means it would meet any future residential emissions legislation (something that can't be provided by privately insulating the property). As far as removing boarding/raising joists is concerned, the user was correct. Unfortunately, with the amount of work we are currently booking (300 jobs per week in the south-east) it is too time-consuming for the fitters to do this themselves, and this isn't covered by the grant scheme. Miller Pattison do offer this service, but it would come as a standard, chargable service. Over 70= Free Certain Benefits= Free Standard Homeowner= £199 for loft. £149 for cavity walls (privately £800 for loft, abt. £2000 for walls, for equivalent service)
