NCC installed underfloor heating across 3 levels at our house beneath engineered flooring alongside a heat pump.

It turns out they used a product designed for tiling, rather than wooden flooring, and did not follow the manufacturer's instructions (which say that self-levelling compound or screed must be added if used below wooden flooring). This means that beneath the floors (which require even heat) there are hot pipes at 50C separated by cool insulation.

Their manufacturer says it's essential to install thermometers beneath the floor to avoid damage to the flooring - this was not done.

Their manufacturer says that concentrated pipes should be avoided or insulated to avoid overheating of the floor. In some sections 7 pipes have been laid together where the pre-cut grooves in the boards normally support 3. In those areas the floor is being heated to 30.5C way above the safe limit of 27C, which the majority of the rest of the floor is at 21C. So both damaging the floor and failing to heat the rooms.

During installation Neil's constant refrain was "I've run my business from home for 33 years, no-one has ever knocked on my door". Yet when we reported the issues with the installation we have had nothing but denials of the issues.
