    AFDDs needed in CU's over the 6th floor or all CU's?

    Work has booked me in for a CU change on the second floor of a 7 storey block of flats. They are under the impression that AFDD's only need too be fitted in the flats over 18m high, or the 6th and 7th floors. I'm pretty sure the regs 421.1.7 mean all flats in a block that high but it's...

    UK AFDD - Has this left a loophole for landlords?

    Recently been working on a system design for a LL. I was told the building would be a three floor 16 room HMO, so the design was done to the current Regs for that use. When the LL saw the cost of AFDD's he 'blew a fuse' and said no way was he fitting them at a cost of over 3K. I explaned that...

I've just recently moved into this house which is nicely equipped with a large 15 circuit CU unit with a split load x2 RCD's but first, I think an EICR would be a good idea to give a starting point reference at least, before any work is done I'm considering having...
