I am having a house renovation done: loft conversion, single-storey side and rear extension and full internal refurb. Currently 3-bed semi in Harrow, NW London.
However, I also asked the contractor to quote for some additional work:
- Cat6/coax cabling
- minor amendments to allow for my wireless (Fibaro) automation system. NB: all that is required for this is neutral at each switch, dimmer/relay modules inserted into deep (45mm) boxes and a bypass installed (between switch and each group of lights) for rooms where loads are too small, as well as relays for the UFH actuators and boiler. And a small wireless sensor stuck to ceiling.
- basic alarm system (which will work with Fibaro wireless sensors)
I've included the full spec below for reference, but what i would like a view on is whether 7.8k+VAT is a fair and reasonable charge for this additional work. NB: standard electrics (most of what is below) are already included in contractor's project price. The contractor insists that 7.8k+vat is only what the electrician is charging them for non-standard work, mainly cat 6 and automation stuff.
