Before moving into our large bungalow just over a year ago I insisted that the vendor had a full electrical safety test carried out based on our surveyor's comments that the wiring in the attic was very untidy and looked as if circuits had been added without care.
Suffice to say that I found out it had cost the vendor £700 for the full test plus £300 for the bathroom and adjacent en-suite circuits to be made 'safe'. To achieve his perceived required level of safety he added pull switches for every appliance wherever they did not already exist (except for the 2kW occasional use down-heaters which already had FCUs). The result was something akin to a church belfry with pull switches for mirror light, heated towel rail, room light, extractor fan and pumped shower.
I want to get rid of this ugly (and confusing!) madness into a combined switch unit outside and above the bathroom door. Plus have proper wall switches for the lights (pull switches do sound through the ceiling and are rather ugly).
The power feed for this muddle gets worse when looking at the Consumer Units. There are two 1970s twelve-way Wylex units in the garage which is not accessible from within the house; one has a 30mA RCD and the other just a 100 MCB . The whole property is wired using multiple radials for the sockets and all circuits are in the attic.
The various appliances in the two rooms in question are powered from a multiplicity of RCDs spread across both CUs but one of the shower pumps is fed from a 40A MCB in the CU with the RCD and this is its only load! It is my plan for this MCB to be used to power everything (except the lights) via the combined switch unit mentioned above. Now to my actual questions:
1. Should the intended switch unit have its own RCD even though fed from a CU with one fitted?
2. Is there a consumer unit range that has a more pleasing appearance than the usual for use in view (there is no cupboard or space to hide it)?
3. Hiding two three-pole fan isolators is a challenge; any reason these should not be in the attic adjacent to each of the fans?
4. Short of a total rewire and updating of the consumer units are there any general helpful suggestions please? I have managed to future proof by sourcing multiple spares of all the circuit breakers and RCD.
