This would be the best place to start http://www.hmrc.gov.uk/selfemployed/tmastarting-up-in-business.shtml As well as registering Self employed be sure to register under CIS that way you only get stung for 20% tax if you sub to anyone instead of 30% or so.

You could achieve it by using an Off Delay Relay, this could involve a fair degree of re-wiring as you would need the relay to control a contactor the could switch the load of the shower, you would also need a button to activate the timer relay. There various types of Off Delay relays you...

Where does it actualy say that Part L Does not apply to rewires? Its just Section 12 of the new Domestic Building Compliance guide 2010 seems to indicate that it does apply to rewires as as it list recomendations for meeting the energy efficency requirements for both new and existing dwellings...

So how is going through Building control and having them send out an electrical contractor who will be a registered member of one of the schemes, any different to employing your own electrician to carry out the exact same inspections and tests.

Depending on what load you are intending to draw from these extra sockets you could always install an RCD fused Spur at the point you intend to break into the existing ring. This would enable you two fit flush sockets and cableing. You would however be limited to 13A supply

It sounds fine, as you say the switches and fittings do have earth's its only that DI singles are used as strappers between two way switching. I wouldnt even code it. Just make a comment that parts of the installation are wired in Double Insulated singles.

Why is using RCBO's not the best option for a TT installation ??

Well i wouldnt touch it with a barge pole. Atlas Kablo is a cable manufacturer based in Istanbul which had its BASEC approval revoked. Now Atom Kablo is also based in Turkey. Not only that Atlas Kablo are based at Perpa Ticaret Merkezi, A Blok Kat:5 No:95 Okmeydanı / İstanbul...

Its probably worse then you think. BS 6004 Table 8. For two and three conductor cables: * 1.5 sqmm cable has 1.0 sqmm CPC * 2.5 sqmm cable has 1.5 sqmm CPC * 4 sqmm cable has 1.5 sqmm CPC * 6 sqmm cable has 2.5 sqmm CPC * 10 sqmm cable has 4 sqmm CPC * 16...

It still makes me smile when I have to replace an immersion element and when opening up the cupboard your greeted by as much earth cable as you are copper pipe..

Just to clarify TN-S does not require an earth loop of 0.8 and TNC-S does not need to be 0.35 or better. These are just typical values that supply authorities try to achieve and can be exceeded there are no regulations covering the maximum values allowed for either supply type.

I think you need to go back to basics as it were, contact the supplier yourself and discuss directly with them about upgrading your own supply. Make no mention about anything else just get them out explain what you want and take it from there. I fail to see how the fact that two properties...

I'd guess since its not to do with the fact that the electrical supplies cross form one building to the other that there only issue is the fact that the two buildings are connected via this door therefore its essentially one building. Are the two building addresses different ? it may be that the...

Before taking and sockets off you would be best of doing Continuity tests on the conductors and R1+R2.

I havent looked it up but from a pure common sense point of view the answer is no. What happens what one supply is being worked on and someone needs to do any work / tests on the rod. They may have to disconnect the earth to the other supply as well.
