    Building a false floor for the new van.

A very nice van to drive, more like a car than a van. However, I had to take out roughly half of the stuff I had had in the Renault as the berlingo was...

    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...
