Rewire ?

Big Davey

I recently bought a house that needs a bit of renovating it has an extension (quite large) that is wired to modern standards (three wire brown, blue, and green) but the old part has what looks like an old 2 wire system ? Is this system ok to run lights and sockets off ?
I am going to get a new fuse board for sure and get the cooker and two power showers wired back to the new fuse board but am unsure if the older style wiring would be ok or best to change it.
Any advice would be appreciated the work will be carried out by reci electricians not myself I would just like some advice (impartial) before I contact anybody.
Thanks

you'll have to get a REC to take a look and advise

Not likley.
It is very hard to know without seeing it.
You really need to get a REC to look at it.
Quotations are generally free.

Back in the "good old days" there was little or no earthing used.
Nowadays earthing and bonding is viewed very differently.

Are any of the sockets can be installed on skirting boards? This not permitted as this is considered a fire hazard.

A new board would be a good start. This will make the installation safer as it should provide all sockets with RCD protection (I am guessing that the older part of the installation does not have this).
Again this has to be seen to be able to give you a proper assessment.
Perhaps you could post a few pictures of the parts of the wiring that concern you?

Does the old cabling have PVC insulation?
If not it should be replaced ASAP.

You may find that a complete rewire is required. If this is the case let us know and we can advise accordingly. It is a great opportunity to make the house more comfortable and personalised.

Old installations are frequently lacking enough sockets, mains heat / smoke / CO2 detectors, RCD(s), earthing, bonding, MCBs, correct sized cable feeding the distribution board etc. The wiring might have been seen as more than adequate when it was installed, but the electrical load is most likely many multiples of what the installation was originally designed for.

Thank you I will post some pictures but I think your right now is the right time to do whatever is needed as there may be fishing of wires and cutting out of walls etc.
I did not notice any sockets or switches on woodwork but as it is a pet hate of mine they would have got moved anyway :-)
I will put up some pictures in the next few weeks and probably seek more advice as I would not mind doing some of the donkey work myself if I was allowed and if it saved a few quid.
Thank you

Detecting carbon dioxide !!!!!

Have you a heating system that burns fossil fuel? Have you gas cooker?

My bad, I should have said CO as in carbon monoxide.
