Boiler Wiring Query

I think Danny just wants to avoid an eyesore - as would I.

Trunking or dangling flex going to a wall socket is pants.

I was referring to the first half of this sentence, and wondering if there was a valid reason (not yet discussed) other than aesthetics...

I would prefer a separate circuit for the boiler like we already have and also don't really want trunking going from the socket to the boiler. 

...I agree with the views on trunking and flex, but if you get something for free or heavily discounted there is a limit in what you can expect in terms of looks.  However, if there is a technical or functional reason for a request, that might carry more weight with the decision maker(s).

E.g. if someone is vulnerable and at risk if the heating trips out, a valid argument might be made that partial mitigation could be achieved by supplying the boiler from a circuit which is less likely to trip due to a fault or overload.  The presence of water, along with multiple high-load cooking/heating appliances, arguably makes a kitchen ring one of the more high risk (of tripping) circuits in the home. As a further example, I personally wouldn't put any sensitive electronic equipment on the same circuit which a microwave is plugged into, even though I doubt the regs would mention anything about that.

Hi, the main reason for having the boiler having it's own circuit is because I read online that it is preferable and if our ring main trips the boiler won't switch off. That is also the reason the electrician last year put it on its own circuit when rewiring the house. 

Obviously from an aesthetical point of view I also didn't want trunking or wires sticking visible in the kitchen but if I have to pay separately for that afterwards I would be happy to do that afterwards.

Here is a link for the video to show the area better. Please excuse the mess, been a hectic day.

That helps with the context.

If the installer can't/won't use the existing supply then the next thing to consider is whether the supply for the extractor hood would be a better place to make the connection, rather than running trunking across the tiling.  Is the extractor plugged in (or hard wired) to something above or behind one of the wall units?

If there is something suitable for making the connection then the supply to the boiler could possibly be run more discretely above/below the adjacent wall unit.

Yes, that may be an option. The extractor is plugged into a socket in the unit above the extractor.

I will try and take picture later show it more clearly.

well this morning i asked my trusted electrician on how he would go about the op's situation by showing the initial photos.

He mentioned removing & refitting the existing fcu adjacent to the existing double 13a socket but as long as that was wired up correctly. He mentioned it will be in eye sight & arms length of any person working on the gas boiler and a suitable label will be printed out and attached to the fcu. 

His idea is to throw dead the existing fcu, fit a plastic cover (assuming it does not supply voltage elsewhere) Remove the wireless diggistat and the customer makes good rawlplug holes etc.

RE use the existing fcu front plate, cut into the metro tiles adapt as necessary and supply a 3 core flex in conduit to connect in the existing boiler to provide hotwater.

His cost (central london area W1) will be no more than £79 (cash) with a piece of paper saying its done to the book.

He mentioned there will be dust and he needs to get working in an uncluttered environment f the cust wants all there gear moved & dust free experience it will cost 3 times more.

Just seen your post further above, Danny - so your sparky has the boiler on its own individual circuit, and dedicated MCB? Clearly the best option is to keep that, then, and to reuse the existing supply.

I cannot see any credible reason why a sparky would not do this - ie just fit another FSU inside that unit.

Anyhoo, bottom line is, you ask them if they'll consider one of the number of suitable alternatives already suggested - instead of their proposed one - and, if they do not, just ask them to not even bother with trunking at all, but to drop the flex down from under the unit, and into the double socket. You'll sort an alternative later.

Kind of my last post on topic, some will be celebrating 

Ok, the existing wb boiler is not that old. Similar to many other gas boilers under third party maintence contracts resulting in never having it professionally serviced or any installation errors sorted.  When they go tech No repair tech will take them on.

Its like having a brand new car just mot'ed and not serviced for 10 years.

So the customer will be left with a wb budget boiler that needs some repair, they can retain the old boiler& flue and sell it on for parts strip out.


So the cost of getting the wiring sorted is already sorted, its free 

Others will disagree but thats what forums are for. 

Happy days

I suspect the installers will take the old stuff away.

...and come up with a dozen reasons why it is 'against regs' or a 'scheme requirement' if the OP requests it be left.

If there's value to the parts the installers will know about it, and fight tooth and nail to keep their perks of the job.

Tbh, the boiler and flue intact with all the necessary fittings foir me as an installer via the trade is worth £95 cash.

Who owns the old boiler i would say Danny30 is the owner and could keep the boiler/flue and all the necessary parts to internet sell them on for around £105 lovely pounds.

Trash removal fees are expensive and if Danny30 takes responsibility for all the trash. Some discount is necessary. Maybe negotiate.


Hey, that could pay for the electrical upgrade !
