I need a Heating Engineer for my Boiler

I need a heating engineer that can repair leaking on my boiler. It is not a gas boiler and you would need expertise on an electric boiler. The boiler in my house is a unit that links up to a main central boiler for the building. we think because of the leaking the pressure if not reaching the radiator as when we turn the central heating on the radiators do not get warm fully. I was advised my another engineer that you would need to specialise in NCU units and to see if you had any parts for this specific boiler. If you feel like you can repair this type of boiler please can you contact me so that I can get a repair quote.

Thanks
