Jim and the team installed a new boiler system. Jim was very thorough in his assessment of what was required, and explained things clearly. This took 2 days and commenced as scheduled. Overall, the installation of the new boiler is good. However, they left behind a lot of waste, for instance several plastic pipes, the old tank in the loft and various pieces of pipe insulation. I was not expecting this, I was told it was only cardboard which would have been left. This has left an extra job for me to sort, and was below expectations.
