If anyone in the North Liverpool or Wirral areas is looking for a good central heating company, _DON'T_ use Merseyside Central Heating Ltd.
They replaced a central heating boiler and hot water cylinder for my
79 year old mother with a bottom of the range, 78% efficient bog standard cast iron boiler, and the hot water cylinder without the factory applied 35mm PU foam. Both in exactly the same location, so no extensive alterations to the pipework, etc.Even though the existing system had no room thermostat and relied solely on TRVs, they didn't upgrade these controls as they are required to do. They didn't even fit a bypass, when the installation instructions say quite explicitly that they should. They didn't supply a benchmark certificate.
All this for the bargain sum of £2,200.
