Curious electrics in kitchen at own house

I live in a council house and about 4 years ago they re-wired the kitchen and fitted new units etc.
Above the cooker, where the wall meets ceiling, there are 3 blanking plates, single socket size, with the 'danger 230v' warning on.
I believe they have something to do with some of the sockets but can't be sure.
This year I would like to put up a cooker hood and so need to drill the wall.
What are the odds on the wires running down the wall and so increasing my chances of hitting one and can someone suggest a suitable wire detector that will do the job but not be a very expensive toy afterwards?

 

You may have more luck using one of these detectors in metal detection mode. Most should do the job OK if you understand how they work.

 

take the blanking plates off and see where the wires are going , sometimes you can see if they are going up/down, not a guarantee - but it may confirm the direction.
Photos would help
Also be careful when taking the blanking plates off that you have isolated the power , in case the wires are just bare behind the plate - should not be , but you never know

 

Is this permitted in a council house?

 

I'm confused. Are you questioning whether a council are allowed to rewire the kitchen or fit new kitchen units in one of their council houses?

 

My mistake, I thought he had done the work.

 

No I just have a son who needs to fry every meal hence the need for an extractor fan.
Recommendations on live wire detectors would be welcome.

 

I have never found one that works with any degree of reliability.

 

The Bosch D-Tect is pretty much spot on every time.

 

At £210 it had better be.
Hammer and a 6” nail does the job too!

 

I have one of these and have no complaints. For £36 I think it's a bargain.
One thing I did find, when standing on a carpet or with rubber soles I got more accurate results if I held the meter in one hand and placed my other hand against the wall. I don't know if this method works over wallpaper as my walls are painted plaster.

It's only the cost of 30 minutes of my time
