    Hi There,
    I'm doing a UFH job and need to get a rough idea of cost for delivered/ poured concrete? The area 20 square meters, which I know is a small area. So this area poured to four inches deep/ two visits (two pours) obviously.
    Any ideas?

    2 pours of 1m³ won't be cheap, perhaps £150 a time. Ring round for costs of 1m³ at a time.

    Underfloor heating is contained within a screed above a subfloor. Normally 50mm to 100mm of celotex is laid then a thin vapour barrier then either track, clipped or eggshelled ufh pipe then 50mm of screed on top.
    You don't put ufh in concrete!

    Was thinking of now an anhydrite self leveling screed, about 50mm ? Been told it's the way to go for underfloor heating?
    Would that need anything to stiffen the finish to then tile on?

    Anhydrite screed is great. Normally use a decoupling membrane before tiles

    Consider the thermal mass too ie. the warm up/cool down time...if you've got a ton of concrete storing heat for hours and then add solar gain you'll be cooking.
