Hi all

Please can someone advise best practice for the following:

1970s extended property with subject extension to rear
Extension adjoins both the house and garage with fuse box located in garage
Currently the sockets in the extension are a radial spur from the breaker
covering the upstairs main house ring main
Similarly the extension lighting is a radial spur from the upstairs lighting
feed

My questions:

In an ideal world I suppose I would have a separate breaker covering the
extension supplies, or have them form part of the existing downstairs
ring/lighting.
Is it a big no-no to power more than one circuit from a single breaker?
There are currently 3 single sockets in the extension, so I presume that the
power to this room should be converted into a ring whether it returns to a
shared fuse or not?
There are currently no spare fuse ways in the CU so it would be an expensive
upgrade for one room to provide individual protection for these two
supplies.

Any comments on IEE Regs compliance welcome

TIA

Phil
