External copper pipe insulation

[alisonw]

I had a combi boiler fitted in the garage recently which has meant a lot of copper pipe external to the house and throughout the garage. Metres of it. None of it has been lagged what should I do and or have expected from the installer.

I’m guessing the gas pipe has been ran external and hopefully not water carrying pipes? As for the ones in the garage then yes installer should have included this in the quote providing you didn’t knock it back for this type of work?
