    I have a 40 year old bungalow with about 3 central heating leaks under the concrete screed at the end of the house facing 5 radiators.
    should I:
    1) dig up and fix the leaks
    2) chase the floor and fit microbore to all radiators
    3) raise the floor and insulate while I am at it.

    any other advice appreciated. The skirting and lower plaster is damaged so will have to be replaced anyway...

    A half normal half microbore system would be a disaster to balance. Very hard to get working

    I had exactly the same problem only found when mould discovered behind a wardrobe. Foam backed carpet kept it from being obvious on the floor as carpet always dry. Dug some small holes until I discovered the pooling in the screed. Not a joint but where plumber had use a knee rather than pipe benders so too mean to even use a joint! I was renovating so ripped it all up as the standard was poor all through the house.
    I would suggest if you have 5 rads it may be worth ripping up the floor and laying underfloor heating so you can install insulation and have a much better system linked in to the existing. Only one lot of mess and it will be much warmer (providing draught proofing is in place.). Wish I had done the whole house but it was not appropriate at the time. If you are handy you can do this yourself.
