What is the make and model no of the RCD? I might have a spare and I if I
have it's all your's for P&P (or just post a picture of it).

The RCD is a Tenby unit, in a tenby C series CU. Installed around year
2000 I think.

I really want to replace it with a different model though, because I
suspect it's the cheapest the builders could find.

One thing I would appreciate is advice on good quality RCDs. I see
screwfix have BG (British General), Wylex, Volex, and MK for between
GBP 20 and 35. I'd probably go for MK, as it's a brand I know, but a
view from someone in the trade would be useful. I don't really care
about a few pounds if it's likely to improve the situation.

I'm assuming that any 80A 30ma RCD will fit in my CU. They all look
pretty similar to me from the images on the screwfix website. If
there's some compatability issues that I should be aware of, please
let me know.

I'll even test it and give you the test results.

I am a little too busy to read all the thread ATM but is this a whole house
RCD?

It's a split load CU with lighting and immersion without RCD
protection, and all the power circuits protected by a single RCD.
