When we moved to our flat, the washing machine was in the bathroom. We bought a new one and Curry's wouldn't install in the bathroom (understand why) so it was set up in the kitchen (fittings existed)

now we want to install a dishwasher in the kitchen and move the washing machine back to the bathroom. Before I post a job, I'd like to know whether an electrician will actually do this job, due to the 'electrics in a bathroom' issue. We're find with it - there is already a power supply and the pipes for the washing machine, just want to know whether someone will actually do this. Otherwise we need to re-think the new kitchen design! Thanks :)

Update 09/03/12 - thanks for the advice guys, will not be moving it back to the bathroom following your advice!

What is a reasonable price to fit exterior lights ( 2 flood lights)?

If only the flood lights were to be supplied by me.

One for the fornt of the house (3.5m away from mains under the staircase)

One for the back of the house behind the kitchen (5m away from the mains under the stair case)

Also what would be generally involved?

Would I have unsightly wires indoors?

Would this type of work require certificates?

Earthing a property

My electrician has earthed our property by means of sticking a long metal rod in one of the flower beds in the garden. Is this the right and safest thing to do?

Thanks to all those who have responded thus far...appreciate your reassurance and yes the electrician has advised that he is certified.....

Thanks electrical Safety Services!! this is exactly what he has done... I was thinking about it being accidently damaged which is why I posed the question.. The job is not finished yet and he has to come back at second fix so I do not have a certificate yet. I will point this out to him and see what happens. Thx again for your sound advice..

2.5mm wire for 4.2kW oven


My electician has rewired the house and installed a 4.2kW oven (with a separate gas hob). The oven radial uses a 2.5mm wire with a 20 amp fuse, and the length of the wire from the consumer unit to the oven is about 4m. My builder has told me that the 2.5mm wire is unsafe, but my electrician insists it's okay because the oven has no hob. Can anyone confirm whether the 2.5mm wire is safe and compliant with the regulations?


Thanks all, much appreciated.

Part P Certificate following a new extension

We have recently had extensive buliding works carried out which involved a full rewire. The work was carried out and a NAPIT certifcate provided after the works were completed. The problem is the local council say this does not equate to a Part P certificate and they won't sign off the electric. I've done my best to insure the trader was qualified, the works been checked and certificate sent to building control but it's not enough, am I missing something?

How much work do I need to do to be 'Satisfactory'

In order to satisfy my home insurance company, I recently had a NICEIC inspection on my recently purchased house (that I will be living in, not rented) which concluded that the condition of the installation was ‘Unsatisfactory’. The insurance company requires it to be ‘Satisfactory’. The property is an old house which I will be restoring over the next 2 years, and will include a full re-wire once all alterations and plastering, etc have been completed. I can understand most of the points that were highlighted in the inspection report and have no issue with most of them, except for 2 (which happen to be the most expensive to resolve!).

First, both upstairs and downstairs wiring circuits were noted to have no earth wire (it is an old house...) and the quote from the contractor which carried out the inspection included provision to re-wire, specifically “to rewire lighting circuitry (point for point as found) in order to provide earthing conductor as needed by the IEE regulations”, at a cost of £1k. My question is whether this is necessary; is there not an option to fit plastic light fittings and switches, or Class 2 fittings, throughout? There are no metal backboxes. It seems to me a waste to rewire now and then to replace in the next 2 years…

Secondly, there is a comment in Section K that not all circuits are RCD protected. The house has a relatively modern consumer unit that (I believe) was installed in 2002 (10 x MCBs, a main contactor, and an RCCB). The 80A 30mA RCCB, fitted within the consumer unit, covers the upstairs and downstairs socket ring mains. The contractor’s estimate quotes the following work: “To supply, fit and reconnect to existing circuitry as found new 17th Edition RCD/MCB consumer unit as required, complete with re-testing electrical installation, including new computer produced certification detail as required by the current edition of the IEE regulations”. I was under the impression that the IEE regulations were not retrospective and that the consumer unit needed only to be replaced if the installation was being altered. Is this correct, or do I need a new unit? Again, I would prefer to install a new unit when I re-wire!

Grateful for any advice as to whether I’m being ‘taken for a ride’!

Addition in response to queries: Sorry, I wasn't clear... The house will be extended, the ceilings will come down to be replaced, and a number of the partition walls will be moved; only then will plastering be done, so any equivalent to 1st fix work will have to be redone. So any chasing of wires done in a rewire will be useful for only a short period of time, etc. Wasn't planning to plaster/decorate then rewire :-)

So, in sum, plastic/class 2 fittings mean 'satisfactory' but undesirable?
