Elderly relatives live in a bunglow, which has a 2.5mm T&E cable running to the garage.
The cable is basic T&E and is not run in a conduit - it's just running overhead, resting on a trellis. The cable must have been installed 50 or so years ago and it is looking slightly perished. I want to change this to make it safer.
Layout
* The run is approximately 5ft - the distance between the corner of the bungalow and the front left of the garage. The height is approx 6 1/2 ft off the ground
* In the house is a 50+ year old CU with 1 cooker, 1 ring main, 1 lights trips. There is no RCD on this box.
* The garage feed is spured off the ring main in the bungalow attic, cable dropped down through soffit
* In the garage there is an RCD CU (installed about 30 years ago) with trips for the socket and the light.
Options
1. Keep the existing cable but thread it through a 5ft piece of trunking with junction boxes at each end.
2. Replace the cable with standard T&E and thread it through trunking
3. Change the cable to SWA and run it overhead, on the trellis
4. Change the cable to SWA, run it down the side of the bungalow, chase out a channel in the ground, run to the garage.
Considerations
Can I do any of the above myself (competent with electrics), what about Part P, would it require a certificate?
