What will the outcome be of my assessment?

[HappyHippyDad]

Hello all..

I expect my full rewire will be assessed this year by Stroma.

It has been done very well and neatly and ticks all the regulation boxes..... apart from socket/switches heights. These I have kept as existing, approx 1350mm for switches and 300mm for sockets.

I have rang Stroma and they have said that a full rewire needs to meet Part M requirements for these heights. I realise BS7671 553.1.6 doesn't give these heights but Part M does and if Stroma say it has to be then there's no arguing really. Also, even though the vast majority of threads say that a rewire does not need to meet part M heights I believe it does as Section 0, 0.2 says part M applies to new builds and also 'Material alterations' of existing dwellings.

Basically my question is 'could they possible make me change all the heights'? I can't believe they would as that's crazy, but just looking for reassurance. I expect it will go down as a note and be checked for the following year to make sure I have adhered to the heights?

Well, what happens in the scenario a rewire where the customer does not want chasing of walls you are doing like for like rewire. If you had to do surface ie mini trunking you would be left with the old boxes at the old hights if you were to do Part M.

Scams making the rules up as they go nice. Anyway what nonsense about socket, switch heights on a rewire.

Thats not quite true as I'm aware. The Documents apply to all building work, with some exemptions.

Part M would not apply to an alteration or extension to an existing dwelling. However, as I and others have already suggested a major refurbishment of a dwelling, e.g. completely renovated for example, requiring structural change, then Part M and others may be applied. There are 'limits on application'.

To say it applies only to new builds, is not quite correct IMO. Sorry if I'm being picky.

I think we are all agreed that in this instance a rewire does not constitute material alteration. But HHD will need to discuss this with his scheme. Its his assessment with them.

I just took it directly from the Part P document.

Thats pretty much what I've decided.
I'm going to use the rewire as its a god damn art work and they damn well better praise it rather than batter me for socket heights!

No you should stand by your guns and school these people.

In recent years I've used several rewires for my annual assessments with Stroma now non of which were questioned over the socket and switch heights. The only times I've complied with Part M regarding socket and switch heights is on new builds and properties which have been gutted back to brick inside and likely to be used by disabled persons i.e. ground floor flats, bungalows etc. I shouldn't worry about it unless of course your assessor turns up in a wheelchair.

maybe searching for brown envelopes that are between 450mm and 1200mm.

One last thang, (as previously asked ) has this guidance come in an email etc, or was it verbal over the phone?

I just took it directly from the Part P document.

I sorter stand corrected. The definition of material change (reg 5), gives 10 examples.

From the online Doc M;
Meaning of material change of use (reg 5), i) the building contains one room for residential purposes, contains a greater or lessor number of such rooms, than it previously did.
I think thats describing alteration or extension?

However, Requirements relating to material change of use (reg 6), does not list i), only change to hotels, institutions etc for application of M1 (access & use).

So give agree with you there.

But then the document bumbles around with not making it less compliant than it previously was or reduction, which I can't decipher! Which was my point really, that Doc M still can apply to an alteration or extension. I still agree that a rewire doesn't constitute a material change of use.

I'll tried to up load that part of the doc, but the screen shot revealed personnel details . Gardeners weekly & knitting monthly.

This is better;

No. change of use specifically means it had one use ie retail or commercial and then became residential. It wouldn't be change of use if you changed the use of a garden into a room!

not making it less compliant than it previously was or reduction, which I can't decipher!

That just means if the sockets are at 300mm you can't lower them but you can keep them at 300mm or higher.

I was recently on a job where an agricultural building which had been in use as a brewery and is now being converted to a dwelling was being wired for its new use as a dwelling. There was a freelance building inspector on site and I specifically asked him if Part M applied and he said no, put the accessories at whatever height the customer wants. I'm with Stroma too but probably won't be taking them to this one on assessment...!

Your first point, if you read item I) in below, and explain for me?



Your second point, its item 0.4 thats a bit gobbledygook.

Midwest I'll check later, remind me of i forget

 

[Wilko]

I haven't the reference to back it up, but I would have thought that brewery to a dwelling job would definitely have triggered the new build clauses for outlet and switch heights. If it didn't (as that inspector says) then is he also saying he doesn't need to see the latest domestic insulation or smoke alarm standards? Just to make a point .

All this debate and as usual it’s all about poorly worded documents .....

Submit them for review by the plain English society ...

Bump.

You lot don't half enjoy making things hard for yourselves...

By simply fitting pull-cords,you can comply with whatever switch height is demanded,using a pair of scissors

This is why,Peter Dinklage put me on Trustatrader.

Just want to throw in a curved ball ... What about above counter sockets in kitchens .... They would struggle to comply with part m

Got that nailed - bench top 90cm and I usually leave another 20cm to the outlet so still within the 45cm to 120cm, just.
