Hi onq,
Yes he did all of what you said, leaving eaves clear, wrapping water tank, putting insulated lid on and am very pleased, he used the supernova silver cavity wall insulation system and for the attic the knauf earthwool loft roll 200m. We can already notice the heat retention particularly upstairs that it is not escaping into the attic.
LowC02design,
Yes he is paying tax - has the Irish Agrement Board certs - it just pays to shop around - we have got quotes over the last 2 years, he was the last to quote. We got a quote off a local insulation company, they were E700 dearer and from what I hear the materials being used would not match up to what we had installed.
