Eastbourne Homeowner
Job carried out by two very efficient men who made no noise,or left any mess and completed the work of removal of old large boiler and fitting of new ' Combi' and new Flu out onto the roof very swiftly,showing that they both knew their jobs well.
We thank them both very much.

Manchester/ Middleton Homeowner
Heating Adviser did not tell us about two factors to do with removing existing fittings, which necessitated additional work by me - after the team had left - the reinstate to a good standard. Otherwise, an excellent installation from start to finish. very impressed by the installation team who kept us informed at every stage and who cleaned up exceptionally well after themselves.
