    I’m currently looking into replacing my 20- year-old Ideal Classic FF 360 gas boiler in a 70s semi and have been getting various quotes for a condensing conventional boiler, as we don’t want a combi. The current boiler works well, we have it serviced every year via British Gas Homecare, but...

    What to do with my Central Heating pipes in this scenario? *Help*!

    Convert central heating with 1 meter into separate controls & meters

    Would it be a big job? Would floorboards have to be taken up etc? How long would it take? Each unit is a single-person flat. Would tenants have to move while it's done, or could it be done in a short time...say within a day? It's an old building - heating is from 70s or 80s. The type of heating...
