Hi folks / electricians !

I need to get a ~30Amp Rotary outdoor isolator switch fitted and wondered what the pistonheads experience is for cost.

Electrician came round. He said the feed would be taken direct from the "box" outside and not from my fuse box (so no "indoor" work)..but it's a long cable run. It would go up 1 side of the house, into the loft, across the loft then out the other side of the house and back down to 1 metre above ground on the other side. Let's say 40 metres of cable total.

How much to do that ? They quoted £625 + VAT....which totally baffled me. Clear access to all areas, a couple of holes drilled for cable entry / exit to loft...then run the cable and "attach" at both ends.

If you are an electician...is this reasonable ? or am I being fleeced !

Thanks for your thoughts / experience.

Hot tub....32 Amp actually quoted for.

I'm no electrician...but I see materials as :
1 * circuit breaker fuse in the outside electrical box
1 * outdoor rotary switch
50 metres of the right cable
+ bits and bobs....

Surely that can't be more than £150 (happy to be corrected, I have no clue..I'm just reacting to a proposed bill for £750)....in which case...nearly £500 labour !! How long can it take ?

Thanks folks. Layout is absolutely simple. Electricity meter box at chest height on one side of the house, straight up to gable end, into the loft...across and out the other side...then straight down to the rotary switch. Easy access to all areas, can't see any problems from that perspective.

Good ideas. Need to get the breakdown and details of what cable as I'm sure I can route that myself and it could be a good chunk of the labour !

Thx

Isnt putting mods in the outside meter box frowned upon?
Just interested to know.
Can anyone comment on this ?

We've now got 3 quotes, all from fully qualified electricians. Only one has mentioned a concern over fitting into the external box. He has said he needs to check with the electricity company to see if they are ok ?

The other 2 have just quoted to take the feed with fitting some type of RCD in the outside box and said that's fine

Thoughts from any qualified electricians ?

3 registered sparks have quoted. Agreed that price wasn't too far out. It's Notth of £500 for all of them.

2 have said they can run "from the outside box" with appropriate connections/RCD. One has said he can't do that without checking with the authorities ? Don't really understand as from what I understand, they have no intention of messing with the meter, just tapping into the supply on the "house" side somehow ?

Interesting that 3 qualified electricians have 2 approaches. All have been good in discussing options for routing the cables (internally or externally).

The outside box is where the meter is...but they can easily acces the cable that feeds our main fuse box in the house. I think that's what 2 of them want to "tap into" ?

No thoughts on the legality of working in the meter box from any sparks out there ?
