Those electrical prices seem really cheap??
How close to mains is the room? 13x double sockets back to mains, the cable alone has to be more than £50 surely?
agreed:
"Electrical
Supply and install 13 double socket including wiring back to mains - 50 pounds
30 amp socket 155 pounds"
supply and install AND wire back to mains?
Sockets are around £12 for a box of ten mate....Also.....
- wiring back to mains? does that mean you're having a new ring main istalled? 13 sockets on one circuit should ideally be on a ring main (32A)
- Also, BS7671 requires that RCD protection is present in your existing mains board and also you main earth readings are within limits to allow the RCD to disconnect quickly enough under fault conditions
Your main equipotential bonding *(Gas and water) must also be up to standard. Gas and water should be 10mm earth cable. Main bond usually 10mm for a Rod, 16mm for PME/ TNCS
in summary, if he's installing a new circuit, then the above needs to be tested and a cert. provided.
Also:
"30A socket = £155" ?
all sockets will do 30A mate - just depends weather they are on a radial (16A or 20A circuit) or 32A for a ring main. Regardless, both are wired using 2.5mm twin and earth cable.
This is basic schoolboy stuff to any half decent spark. It is your absolute right to expect this stuff to be looked at, planned, tested and certified so make sure you ask.
The first thing any spark should be doing before touching ANYTHING electrical in your house is assessing:
RCD protection present
Main earth tested and withing standard
Presence and tesing of Gas and water bonds
Overall condition of existing wiring/ installation i.e IS IT SAFE?
looking at your description, if he's installing a new 13 socket ring main inc wiring and materials, £50 is FAR too cheap. Also, for a domestic premisies, 13 sockets on one ring seems a little large. For convenience sake, Id install 2 separate circuits then if on has a problem, you can always keep the second powered up.
***EDIT****
Just read this:
sorry that should be 13amp socket at 50 quid each total of 40 sockets
Now that seems expensive. Most sparks usually charge install of the Circuit (i.e new ring main inc, cable, MCB, testing and cert) at say £150, then a say £10 - £20 per socket....UNLESS there is an EPIC amount of time and effort involve lifting floorboards, crawling under floors, chasing out walls, climbing in lofts etc. Obviously Job specific stuff which is difficult to gauge without at least some pictures
The plastering prices look pretty good mate to be honest....if he comes recommended I'd go with that.
