Neat job, I have a love/hate relationship with cage clamp terminals, we use them a lot in the panels at work. Sometimes they work perfectly, other times can be a real pig to release/insert cables.

Yes, I'd not used these ones before. I used one of the proper tools (just a flat blade screwdriver, really) to open up the clamps. This was necessary for all the old stranded cable and easier for the modern single strand cable. There's definitely a knack to it, getting easier as you get used to exactly how hard to push and which way to lever to open the clamps.
I tried removing the cable from one or two and found it very difficult, so maybe I need more practice.

Actually, there was one thing that concerned me; running cable behind the DNO's meter backboard. I've seen it done loads of times, but there's a risk of damage to the cables from over-long woodscrews fixing the meter, etc to the board. Anyone come across a real problem with this?

A very neat job, one thing that concerned me a bit is the din rail earthed? in the junction box? and why not use a bigger fuse board? You should be allowing for future expansion of the installation, i'm certain in the regs it states a maxium of 70% should be used on a new installation. other than this a really neat job.

Only thing I didn't like was socket's labelled north and south, not seen it done before but could make things potentially confusing for someone with no sense of where north is (ME!!!)
And in regards to meter tail's, what's the problem with keeping both inner and outer sheath the same length? I have always done it like that, I wrap a bit of blue or brown tape around the live or neutral

Thanks. The number of ways was determined by the customer, my Dad, who's a retired electrical engineer and I wasn't going to persuade him otherwise! They've done all the additions they want in that house (small extension) and are happy with one spare only. The spare way was to be blanked, but the supplier of the RCBOs sent a 30A instead of the 20A, so he decided to leave it in there rather than return it. The most likely use for the spare way would be for charging an electric car, but they've no specific plans.
As far as the unearthed DIN rail goes, the point's been answered. If it's OK for the CU manufacturers, it's OK by me. After all, it's only accessible with the cover removed.

Yes, we had some discussion about the labelling. Problem is that you'd never get a complete description of the points served on a small label (eg, "kitchen, plus two sockets out of three in dining room, plus one in hallway, plus two out of three in main bedroom"). Using left and right, you'd have to say whether looking AT front of house or looking OUT of front of house, so not definitive either. It was the best we could come up with. We're going to add a floorplan with the points marked with circuit numbers.
Unless it needs to stay on (exposed cable), I always cut back the outer sheath of tails to reveal the insulation colour. Although not likely in the short term, tape can eventually get old and fall off. Ideally I'd use tails with brown or blue sheathing, like the meter fitter has used.

Next time you might want to use GXD glands for the SY:biggrin:, nice and neat though.
