Checked again today and switch fuse has an 80A. Took some pics of the t&e serving the CU, as you can see theres no glands, no cleats, no rcd to be found. Not sure if theres mechanical protection where the t&e goes into building; what are your thoughts on this. The building was constucted in 2016.
Okay, never considered that would be called a submain so that's good info. Will check tomorrow when the house was constructed but im sure it no older than 5 years.
Its not a sub main, its a semi detached house with its own single phase supply. The switch fuse is there as the tails are longer than 3m, the load side of the switch fuse is t&e which I can only assume is going the the CU. The switch fuse has 100a on it
Im not entirely sure as all wiring is back entry into CU, proper tails go from main DNO Fuse to meter and then to switch fuse; from the switch fuse its t&e. So I assume yes it goes to CU
Theres definitely no rcd protecting the tails; my issue is I cannot see if the t&e is mechanically protected or not when it goes into building so will note this on the cert also. Is it usual to run tails in t&e on new builds and put in conduit ?? That's a really subjective question.

Looks like a separate 16mm main earth is run alongside the t&e, I cannot see if the t&e is mechanically protected on way to cu but I doubt it, so yeh, no rcd for that added to the list. I will need to take fuse out of carrier and have a look, maybe its 80A afterall. Yeh PFC looks good, don't...
Did a job earlier in a new build, part of a 5 year old new build estate in the darkest depths of kent. Anyhow opened up CU and saw 16mm tails so assumed would be on 80a fuse as there not huge demand. Then outside to check service head and main fuse is labelled 100a ?, the tails are 16mm t&e.
