Thanks, John. The SPD has actually only been installed since yesterday rather than for months, but I still would feel happier if they replaced it with a fresh one on Monday. I didn't know the SPD requirements dated back that far. My original reason for asking them to come back and retrofit an...

I don't think I ever saw the earth wire. They arrived with the MCB and SPD already unpackaged. If I'd seen the unused length of green/yellow I'd have queried it at the time.

Hi, I had an additional consumer unit installed in October as part of a solar install. It's a Fusebox 6-way RCBO board with circuits for 2 x inverters and 1 x EV charger. Yesterday, the guys that fitted it returned to retrofit an SPD - which wasn't fitted at the time (probably because it was...

Thanks. I'll try that at the weekend. And yes it is an S-plan system. It is still the original open-vented HW cylinder, although I'm not sure where it vents to now that the pipes to/from the F&E tank are capped off. Presumably it vents to the expansion vessel in the garage and then to the...

Throughout the time I've had it as a sealed system (about 14 years) it's required top-ups every month or so. I've always put that down to things like a weeping bottle vent (fixed at the weekend!) and other small leaks that I've assumed would be inevitable in a system that dates from the last...

Hi, On Saturday morning I started draining down my system ready to do a few jobs that I'd been storing up for a while. It's a big system with 8 x double panel rads, 1 x single, and 3 x towel rails plus the hot water. Within a few hours, the system had drained enough for me to be able to do the...

Hi, I’ve got a garage which has what seems to be a bitumen felt DPC. Originally there was pointing over the DPC but over the last couple of years this has come away so the edge of the DPC is now clearly visible between the two courses of bricks all the way round the building. See photos below...

Thanks flameport and JohnW2 for your helpful comments. I went with your suggestion and did all the new sockets as spurs. All working a treat. :-)

Well I never knew that. So (provided you can cram four cables into the back on one socket) you can spur two double sockets off one existing socket on the ring, but you can't spur off from a spur (i.e. daisy chain). Have I got that right?

Minimal. It's going to be powering a network switch and a couple of IP cameras. There's minimal junk in there - that's all in the loft of the house! The electrician I spoke to suggested conduit was needed because the cable was potentially at risk from human or rodent damage if it was just...

Thanks, John. Re-phrased questions were the same but without reference to a new ring. ;-) The TPC recommended mechanical protection in the loft space on the basis that it wouldn't add much to the overall cost and reduced the risk of any damage from, for example, mice.

Apologies if the date is wrong. It was copied directly from the Department for Communities & Local Govt website. The person is already on board. In an effort to steer this topic back to my original questions and away from discussions about who can/can't do the work, I'm going to rephrase my...

Point taken, John. But in this particular case, the fact it is notifiable won't cause any extra hassle or expense. So that, plus the fact that if I did it with spurs I'd need two spurs off one of the existing sockets (which is obviously a no-no), means I'd rather go for the new ring. And of...

My understanding is that as from 6 April 2014 a person who is registered with a third party certification scheme for electrical installations in dwellings will be able to check domestic electrical work that is undertaken by others and certify that it is compliant with the building regulations...

Yes, having those two downstairs ones as spurs off existing downstairs ones would be an option. But the cable routing would be more complex that way compared to making them part of the new loft ring. Hence my question number 1 in the original post.

Yes, I know - but given that I want three new sockets in the loft that would mean doing a spur off three of the existing downstairs sockets, which seems a bit messy. And that still wouldn't give me the extra two sockets that I want to have downstairs....

Yes, I am aware and it will be checked for compliance after the work is done - which is why I am asking the above question sin order ot ensure that ti does comply.

Hi, I have a detached double garage with an existing electrical supply. The consumer unit has two MCBs that are used for lighting circuits (internal and external) and two 32A MCBs. One is spare and the other is used for a ring main. I now want to do two things: install two extra sockets in the...

PROBLEM SOLVED! When I opened the impeller housing last night I'd put it back on the wrong way up. Doh! All working fine now. Hopefully this thread will help someone else out in the future though. :)

When it's on 100% cold the water comes out of the shower head at a slower rate and hits the shower tray less firmly than when it's on 100% hot - so I guess I'm talking about flow?
