    All the specific guidance I can find stating that underfloor heating is notifiable seems to refer to an outdated version of Part P, and I’m trying to understand why generally everywhere still treats it as notifiable. If a dedicated cable already exists from the consumer unit (so no new circuits...

    My mother moved into her three bed home in 1960 and it had underfloor heating in the living room.

    underfloor electric heating as an afterthought without dedicated wiring

    I'd really like to install underfloor, electric radiant heating in my bathroom. The space to cover is very small, probably 25-30 sq ft. once the tub and vanity are factored in. Not having planned for this, we don't have a dedicated breaker for it. Current set up: we have two junction boxes...

    Fused spur rating for electric underfloor heating

    Builder installed 175w / sq metre in an area 6.7 x 3.5. What should the fused spur be rated at and should it have a contractor as well? Am I correct in thinking it is drawing just over 17A therefore 13A fused spur is insufficient? Thanks
