[Dieseldogg]

Anyone no what the sq metre rates are for insulated boards? It's 12.5 mm an 25mm , I've heard people say from 1-5pence per mm of insulation. Also it in a massive barn an don't no how much more to charge for working off towers, cheers

Don't go in less than £15 a metre in those areas mate. Double that in London...
