Looking at this document the old table X pipes had walls 0.7mm for 15mm and 0.9mm for 22 and 28mm I get CSA of 15mm at 31.4mm2 22mm at 59.6mm2 and 28mm at 76.6mm2 😃

You would have to ask JPEL/64 committee why they omitted bs7288 rcds (includes srcd socket outlets too) in the 18th. No BS EN numbers were quoted in previous editions as far as I can see.  One guess is that you have both latching and non latching types in the same standard, which for socket...

Depends on whether the cable coming down from the ceiling has anything else attached before it joins the ring, and whether it is surrounded by thermal insulation etc. Note that an RCD fused spur to BS7288 is not in the list of RCD types recognised by reg 531.3.6 and therefore does not afford...

Refer them to latest Gas Industry Unsafe Situations Procedure Here (specifically to 3.3.2) ie There is a duty to inform the responsible person in writing. We were advised in training recently to preferably get a signature to prove they received the bonding notice. That is it though, it is not...

Gas fitters don't have the right to disconnect. If an immediately dangerous situation is identified, we ask permission to disconnect. If refused then tell gas "dno" who do have the right of entry and disconnection.

The logo of your scheme provider, if any, might help

So 18th is out in june? you have 20th, that would be August this year by my reckoning.

19th edition Andy? Oh and lotto numbers please, PM me is probably best so we don't have to share.😁

It is dated Feb 16th so we have a few more days before it becomes a thing of the past. 

But is the 2 way lighting fed from upstairs or downstairs? Switch off the upstairs lights at the breaker, does your working light ( the one you are taking switch live from) still work?

I think you mean you have 3 cables going into the non-working light, loop in, loop out and switch cable. It is the switch cable that is terminated in the junction box. So it should be possible to connect the switched live of this cable to the switched live of the working switch cable. But they...

Spot on 😋, well done to you both.

From your results it seems the mid position valve is wired correctly and that the programmer is telling it to divert the flow correctly. But from your earlier posts the heating and hot water are plumbed in the wrong way around. You could get the plumber in to fix his/her mistake, drain down...

Did you use bubble wrap? Or put it in one of these https://www.postofficeshop.co.uk/padded-and-bubble-envelopes/mail-lite/mail-lite-plus-oyster-bubble-envelope-mlpc-0/

looks like a Honeywell mid-position...

Did the emergency electrician leave your failed rcd? It belongs to you and is your proof of British Gas's shoddy workmanship. I think you, or the electrician should report the incident to the health and safety executive via RIDDOR http://www.hse.gov.uk/contact/concerns.htm this page says that...

I asked because I think you give a choice of main switch to right or left. It would be nice to have numbers accordingly. Thanks

They look lovely Dave. I noticed the earth bar numbers are left to right in the first pic and right to left in the second. is there a choice of stickers to use?

perhaps one of our newest members @geek84 may be able to shed some light on the matter. Being our resident tax adviser  :Salute

It sounds like you have heating and hot water controls the wrong way around. Turning up the cylinder stat should have no effect on the heating. The bathroom radiator getting hot all by itself could be due to one of two things. Some systems are designed with the bathroom rad tee'd off the hot...
