Having finally completed the re-wiring of the downstairs ring main in the house we have just moved to, I'm now left with the problem of the upstairs ring and downstairs and upstairs lights.
The problem is that the Consumer unit in under the stairs (split flight with 90 degree turn two thirds of the way up) and without completey wrecking the staircase there is no way I will ever get at the existing cable.
After a bit of lateral thinking it struck me that I could just take the three circuits under the downstairs boards and then up the brick work which is exposed in the lounge after ripping a partition wall out. This will then be subsequentally plastered. The cable runs (4 in all 2 x 1.0 for down and up lights and 2 x 2.5 for upstairs ring) would all be within 20cm from a corner.
Would I need to armour the cables at all, they wouldn't be very deep (15 to 20mm) from the surface of the wall when plastered.
Indeed would it be a good idea at all?
Thanks,
Chris
