Reading Homeowner
All materials were delivered as arranged. All work was carried out as quoted and everything was left clean and tidy at the end of the installation. All flooring and worktops were covered where possible. I am a pensioner and the different engineers were all very affable and helpful where decisions had to be made which means a lot to someone living alone. I hasten to add that I did supply endless cups of tea (or cold drinks) to keep everyone happy!!! The engineer who was 'in charge' of the installation phoned me next day to make sure I did not have any problems.

No discussion took part as to which boilers were available. We were told that the boiler would be better than our last one which is not the case. (May be more efficient). Hot water takes a very long time to reach the tap, let alone how much water is wasted getting to it. At the moment we don't use the hot tap as it takes too long to wait for it. My old water boiler was far quicker. New smart meter fitted but not registering usage at offices or on handset so can't see how much gas is being used by appliances as advertised, only electric. Several phone calls made (at my expense) but nothing done about it.
