The time to complain about unqualified workers was when they started on site!
Its too late when they have finished! None of the remedial works you listed need a qualified person!
The requirement is for the boiler to be fitted on a "clean" system and to be fitted with inhibitor!
Also the benchmark certificates for boiler and cylinder should have been completed by a qualified person! That is VERY important. Also they should be notified to Building Control. THESE are all very important and cannot be done by an unqualified person and most likely have NOT been done!
I dont disagree that he has not done a totally good job but yo should give him the opportunity to put them right first.
