OK thanks,
this is the way it's looking..
1. Lighting 6A (4 beds, ensuite, wardrobe lights)
2. Lighting 6A (outside lights)
3. Lighting 6A (extension, kitchen)
4. Lighting 6A (hall, bathroom, toilet, extractors, airing)
5. Radial 16A (utility w/machine, t/drier, ironing, sitting room, study)
6. Ring 32A (4 beds, hall sockets)
7. Ring 32A (kitchen sockets, extractor, d/washer, kickspace heater, workshop sockets, dining room sockets, upstairs (one room) sockets, lobby socket.)
8. Cooker
9. Shower
10. Smoke detectors
11. Central heating
12. Immersion
I realise some of these can be joined, but I'll probably go for a MK 17 way split load, so can afford to keep things separate.
