I pay just over 1000 pounds per year service charge and that includes heating and hotwater from central boiler. Heating is very warm, oodles hot water BUT partly because it is Grade II Listed, and partly due to age of building and partly becuase of Freshwater (Freeholders) there are endless other costs. I have just paid several thousand in past year, for my share of new water boiler, major refurbishment of common areas. I love the building but the extra costs have always been high
