Hi,
I've been lurking on this forum for a while but have taken the plunge to sign up & seek some advice.
I have a 1930's built semi detached property that I am currently renovating. It has three reception rooms plus kitchen and a downstairs W/C.
Upstairs there are three (double) bedrooms, bathroom and separate W/C. As part of the structural repairs to the roof we have taken the opportunity to install a bedroom and separate shower room with w/c in the roof void. This is currently in progress and is being done under PD with building regs. There is also a detached garage that is to be demolished and replaced with a larger version which will also incorporate the garden shed.
I have also applied for planning to build a side extension.
The property is in need of a total rewire for which I have drawn up the following specification:
Scope of works:
To provide a complete re-wire to BS7671:2008 of the above premises for power, lighting, heating and other circuits as detailed below or shown on the supplied drawings.
All electrical work is to be designed, installed, tested and inspected in accordance with I.E.E wiring regulations (17th Edition) and be undertaken by an installer registered under a suitable electrical self-certification scheme, or by a suitably qualified person, with a certificate of compliance produced by that person at the end of the works as authorised by recognised certification bodies for issue to Building control.
List of works:
• Supply and install 1.no. Fuse board with breakers /isolators and associated cabling to loft space conversion. No. of ways to be determined at time of survey and in discussion with client and builder.
• Supply and install 1.no. Fuse board with breakers /isolators and associated cabling to proposed new garage. No. of ways to be determined at time of survey and in discussion with client and builder. External ducting /trench by others. NB. Lighting and power requirements cannot be confirmed until construction drawings are issued and are to be quoted separately.
• Supply and install 1.no. replacement main fuse board with breakers /isolators and associated cabling. Location as per existing. No. of ways to be determined at time of survey and in discussion with client and builder.
• If required, upgrade main tails to 25mm.
• If required, upgrade main earth to 16mm.
• Upgrade main bonds to 10mm.
• Allowance to be made for additional lighting and power circuits to proposed extension. Draw wires and cable routes to be provided for same.
• Installation of 46no. MK Logic Plus double sockets K2747WHI* to locations indicated on supplied drawings.
• Installation of 3no.MK Masterseal 56482 GRY IP64 rated external sockets* to locations indicated on supplied drawings.
• Supply and installation of light fittings (bayonet style) and associated cabling. No. to be determined at time of survey and in discussion with client and builder.
• Supply and installation of standard down-lighters and associated cabling to specified rooms. No. to be determined at time of survey and in discussion with client and builder.
• Supply and installation of switches including 3no. double strapper circuits associated with all lighting requirements. No. of switches to be determined at time of survey. Switches to be from MK Logic Plus range unless otherwise agreed. Where multiple switches are to be installed such as the hallway, MK Logic Plus Grid Plus should be used.
• The supply and installation of a number of radial fed non switched spurs for boiler, underfloor heating(bathroom), thermostat control, fridge, garage door controls, network rack and provision of a spare feed for future use. Exact number of feeds to be determined at time of survey. Appropriate spurs from MK Logic Plus range to be fitted.
• Installation of cabling to 2no. shaver sockets (supplied). 1no. to 1st floor bathroom and 1no. to loft bathroom.
• Installation of 1no. cooker circuit and cabling.
• Installation of cabling for alternative cooker location.(labelled,un-connected)
• Supply and installation of 3no. smoke detectors and associated cabling in accordance with current building regulations.
• Supply and installation of extractor fan and associated cabling to loft bathroom in compliance with or in excess of architects specification as detailed on drawing 998/17 (not supplied). Fan to be approved by client prior to installation.
• Supply and installation of 3no. extractor fans and associated cabling to 1st floor bathroom, 1st floor w/c and ground floor w/c. Ducting, (if required) to be specified and installed by others. Exhaust location to be agreed by client-external holes to be made by others. Fans to be approved by client prior to installation.
Heating Controls
• Supply and installation of Belden 9538, 8 core shielded cable to 12 no. thermostatic control points cabled back to heating manifolds.
• Supply and installation of Belden 9538, 8 core shielded cable from heating manifolds to a central position indicated on supplied drawings.
• The above to be first fix only and in accordance with provided wiring diagrams. Location of thermostats to be confirmed at time of survey.
All chases, for both electrical and heating to be carried out by others.
Allowance to be made for the supply of back boxes as required in addition to those already supplied and installed by client.
*Please detail cost option to supply and install specified sockets.
This, in conjunction with a set of detailed and annotated A3 sized 1:50 plans were supplied to the Electrician.
The following was also initially specified:
18m integral ducting LV, and 230v segregated.
Low voltage.
1- half size rack to be sited in new garage cabling to be routed via external duct ( duct installed by others).
1- Olsen block 6way.
6- telephone outlets fitted and cabled back to new half size rack and labelled only.
8- data points fitted and cabled back to new half size rack and labelled only.
8- television points fitted and cabled back to new half size rack and labelled only.
To carry out all of the above, I have had an initial quote of £18K plus VAT. This was then revised to £15K +VAT.
The house is unoccupied, no upstairs ceilings, no ceiling in the kitchen, no floor coverings upstairs with all boards loose. Downstairs has no floor coverings land all boards are loose. All chasing will be done by others as will making good.
It seems somewhat excessive even for "darn Sarf!!
I've since revised the spec to just what you see in the first part of the post & have taken out all data, coax & telephony.
I think, I'm looking at between £6 & £8K but I'm struggling to get anyone to look at it to see how realistic this is.
I'd welcome any input on this.
