Certificate For A Conservatory

[Sidewinder]

Now this is a difficult one because I don't want to taint anyones opinions, so I am not going to say what I think.

If you were wiring a conservatory for a domestic client within the next few months, you are installing, lights, sockets and electric under floor heating.

I'm not party to the details of what the exact modifications are at this point in time.

It is backing on to the kitchen, there is a ring final in the kitchen, and a light circuit.

Would you issue an MWC, or an EIC, or would it depend?

I would do a poll, but, I don't know how!!!

I have my opinion, and I have given it to the person asking already, I would just like to have some ammo ready for when the conservatory installers come back with, "it doesn't need any certificate"!

 

[Lurch]

Assuming you are connecting the sockets and UFH to the kitchen ring and lights to the kitchen lights then 2x MWC would suffice. Nothing wrong with doing an EIC though.

 

[NozSpark]

It's usually very difficult to get a lighting circuit into a conservatory and the lighting is often quite minimal..... so usually I find that the lights are supplied via a fused spur off the socket radial extension

..

So I'd say that a MWC will be quite adequate

 

[Essex1]

Either really. A MWC would meet BS7671 in my opinion and an EIC would go over an above.

 

[Rob_the_rich]

conservatories can get pretty cold, so electric ufh might not be enough. possibility of needing additional panel heater(s).

kitchen ring might already be fully loaded

might need a new circuit for ufh and one for sockets, I which case EIC.

So, it depends

 

[kerching]

Spur lights off power

Power from kitchen ring.....DEPENDING on size of UFH!

If washing machine and TD are on kitchen ring it may me too much.....so in this dase it would be an EIC, otherwise MWC

So, in essence, i have not answered the question really

Question was vague anyway.

 

[Sidewinder]

Deliberately, vague as I'm not doing the work, I just NEED to ensure that the installer does not compromise the existing install.

I might end up being paid to go and I&T the lot after as an "expert witness" anyway.

 

[Doc Hudson]

Where feasible, I would prefer UFH to be on its own dedicated supply. However if it is practicable to run a new supply for UFH, then it may be  better to either run two supplies or one big enough to cope with all the conservatory power and leave the kitchen unaltered. This option also means you are only testing your own new circuit(s) not having the risk of finding broken ring legs on the kitchen circuit. In which case its an EIC.  If a new circuit is not feasible and you are just extending one or two circuits then its just one MWC for each circuit you extend.

Bought a conservatory from B&Q?

:slap

 

[Sidewinder]

Not at my place either!

Not sure who is the provided of the conservatory yet.

 

[SPECIAL LOCATION]

Some conservatories get ruddy cold in the winter and if the owners are getting on in years they often feel the cold more, so can have the heating on for longer periods than average.....

I'd want some serious consideration of the kitchen ring before I looked at spurring the floor heating off it.

Depending upon how far round the ring all the big kitchen appliances are located

just sticking the floor heating onto the circuit at random could cause a bit of excessive loading down one half of the ring. 

Unless it really is a piddley small floor heat mat, then I think I may go for an EIC anyway just to make sure I can verify I did all possible tests to cover my rear end in the event of any future issues coming back to try and bite me.

If no floor heat then probably  just MWC(s) or two.

Hmmm

Not having seen the job or existing set up or knowing the UFH requirements:

1. extend existing ring to include fused spur for lighting & another for UFH then MWC (caveat if RCD/RCBO required then EIC due to change of protective device, make a note of alterations to circuit)
2. extend existing ring + spur for UFH & extend existig lighting circuit again MWC (caveat if RCD/RCBO required then EIC due to change of protective device, make a note of alterations to circuit)
3. extend ring for sockets extend lighting for lights  = MWC new circuit for UFH = EIC  (caveat if RCD/RCBO required then EIC due to change of protective device, make a note of alterations to circuit)
4. or drop in a submain for the conservatory = EIC (as per last weeks job....................ahh thank you)

Was asked much the same by another forum member at the weekend.

Is this in Wales and still under the 'old' version of part-p notifiable jobs?

Electric floor heating systems used to be classed as a special installation and thus need notification to the LABC.

:B-   :Salute

Either way the mysterious Masked Sparky should  issue a cert of some sort .   None of us know unless we know the possible loading of the kitchen ring , it may be lightly loaded.

I would add though , that having just finished a new build c/with conservatory I  was told that the building regs forbid the installation of a radiator in there because of the wastage from such a building .

I sumise that a grossly  inefficient floor heating mat  would also be classed the same in the building regs .    Conservatory heating as regards Bldg. Regs is a portable appliance .    This is what I was led to believe .

So  lets see ,  I struggle to remember all this ballcocks but is it not a MWC if only extending a circuit and a EIC if a new circuit ?   

Edit ::    As Specs says  , floor heating IS in the  Special Location chapter so is it the Welsh version of Part Pee too  ?

So no heating is allowed, but we can leave it as a massive haetsink though. If this is correct then I am officially throwing my hands up and starting a new career as a window cleaner, or milkman.

There is one on here who could not hack it as a Milkman...or so,I am told

Just Saying

This arose Lurchio because I questioned the heating guy who had installed a flow & return from the CH , blanked them off and was having them pastered over ,,,to return when it was all passed off to fit a radiator ,   hence my thoughts that a heating mat would come in same catagory .

Forget the milkman thing Lurch ,  there are hardly any left these days .   And who knows a window cleaner that is still at it after a month . ?

 

[Lurch]

Time to retire then. Anyone want to buy lots of tools and a well used van?

I personally know a.guy that started off with a bucket, sponge, and set of ladders, he sold his business about 10 years ago for close on 40 million,
