Hello Everyone

Despite buying electricians gloves, other ppe, 25mm tails and the switch itself I'd still rather it be done by someone a/ qualified and b/ has done it many times before. Only worse case would I consider c/ ....

Anyway, I guess there are some variables so maybe hard to get an approximate price but I'd have thought on my board surely it would be less than an hour's work to pull the main fuse and fit an isolator after the meter? Assuming there was no issue with the DNO (sse) which I think there wouldn't be for a NICEIC etc electrician, and assuming the existing tail lengths are plenty long enough out of the meter, how much would I be looking at? £200 ?

Also, since the work might involve taking the tails out of the existing CU and routing them to the new isolator, could the electrician we hired be obliged to shut down everything if he thought the CU was unsafe? That is actually my biggest fear with hiring anyone rather than doing myself.
 
I think you need to readdress your biggest fear. If your installation were to warrant immediate isolation by a professional electrician, he/she may be saving you and your family’s lives. If you DIY you may learn the hard way. Have a word with your home insurer in the morning if in any doubt.
 
I was hoping to get an approx cost. I was assuming the work would be something like:

remove load
cut fuse carrier seals and remove carrier
move tails from CU into new 100a dp switch
fit new tails from output of switch into CU

As far as I know the existing installation is not dangerous but it is old. Most qualified electricians I'm sure are honest but there are probably plenty who are not.
 
Then the SSE are wrong as we cannot legally pull main fuses. Only the DNO’s and power supplier companies can do that.

This was their reply just now. I have to say wrongly or rightly I'm more inclined to believe what they tell me.

Hi *****, thanks for getting in touch. We are the Distribution Network Operator and own the power lines outside as well as the cut out fuse at the property. Our equipment is all located before the meter and our engineers are not trained to work on the internal electrics at the property. A qualified electrician would be required to install an isolation switch, they would normally need to have NICEIC qualifications or this equivalent to ensure they are able to isolate the power at our fuse to complete this work. I hope this helps. -***
 
SSE allow registered contractors to pull fuses and reseal. An enlightened view that is not shared by other DNOs as yet.


Thanks that's interesting. So only a subset of qualified electricians that have signed up to be a registered contractor can do it ?

How much are they likely to charge me ?

My guess is they'd charge me zero because they won't do it without wanting a load of other work including at least testing the existing installation and probably upgrading the consumer unit.

If that's the case, think I'll risk my life.

We can install a double pole isolator and attach (tails)cables from this isolator to the fuse board( consumer unit), but we cannot touch the=tails coming out of the meter. The supply company would have to pull main incoming fuse and connect the tails from meter into the double pole isolator.
We as electricians are not legally allowed to pull the main incoming fuse.

I take back my 2 previous posts as I didn’t know this was an option in some areas.

I have to say it’s aboutbtime this happened, unfortunately I suspect it’s not happening in most areas. It’s not available in my area in the south west.

It would be wrongly. It is an offence to interfere with the Supplier's equipment.

EDIT: I have read the comments that SSE are one of the very select few DNOs who authorise this.
 
Even with the correct training, tooling and PPE you still need to be MOCOPA registered to work on sealed supplies.
 
Then the SSE are wrong we cannot legally pull main fuses. Only the DNO’s and power supplier companies can do that.

What's the reg/SI to back this as I'm sure it was removed in the latest edition

As above, do we actually have it chapter & verse like they do with gas meters and The Gas Act?
 
Hi - as you’ve found, the provision of a service isolator between the Meter and the Consumer Unit can be a bit confused. The fuse is owned by your DNO (SSE in your case). The meter is owned by your Supplier (folks who send you the bill). The meter tails linking the meter to the consumer unit are your property and responsibility but you are not permitted to touch the meter. So if the cables out of the meter need changing (insulation damaged, current rating too low for a new load etc) then usually your electricity supplier will need to be involved.

Depending on who is your electricity supplier this can be fast and cheap, or slow and expensive. I work in an area where SSE is the DNO and I get first rate assistance from their metering guys for Customers that buy electricity from them. The other suppliers make their own arrangements and so charges and delays are variable. Just my experience.

If you’d like to post a pic of your meter and cables I may be able to be more specific :) .

It’s not in our regs as our regs don’t cover that part of the installation. It’s part of the supplier regs.

The suppliers have there own set of regs that I am not privy to and not familiar with.

Why do you want this isolator in the first place?
Are you planning on a DIY consumer unit replacement? If so I would strongly recommend not doing this but having a qualified electrician who is registered with a part P scheme do this work for you. Otherwise you may be placing your life at risk along with the lives of everyone else in the property.

Thanks. Very informative. Pic attached.

My DNO is SSE but my supplier is pretty awful about everything - TogetherEnergy. The existing cables out of the meter are in good condition and the load will not be increasing. They look the same size as my 25mm tails and the ones into the meter look bigger but I could be wrong.

I might look into NPower from the advice above - thanks whoever suggested that.

I also understand why you couldn't possibly engage with a random diyer on the internet on how to perform notifiable jobs and I wasn't expecting that. I did hope to get a ballpark price for fitting the isolator or at least to have it confirmed that nobody would take on such work.

(mcb on one of the 5a, 1mm circuits was removed at the time as I was changing a lightbulb....:cool:

What a palaver about fitting a isolator
Just as a comparison,if this were my job it would probably have been done in ten to twenty minutes
Maybe,make a decent offer on here with a price you are willing to pay and maybe some kind soul living local will oblige

If you read the DNO terms of service its normally beach of contract to touch their equipment. Its also actually illegal interfere with DNO equipment. Why put yourself in the firing line if the customer can pay £60 and have an idolator fitted before you arive?

I agreed with the £60 job when it was posted, but for me and regarding the suppliers equipment

I have fitted and will likely do so in the future scores of isolators without touching or interfering with any suppliers equipment
Its known as working live,it was once a task that did not cause consternation and anguish to those in the trade
