I have just had a central heating install carried out by a GasSafe engineer. His work appears to be of a good quality however in the loft, the lagged plastic pipes he's used run over everything (i.e. the truss / bottom chord, insulation, boards, etc.) and not through or under anything. Is this acceptable? Will it cause problems if I was to sell the property? Should I insist it is redone?
Thanks in advance.
