Location for New Recessed Meter Box

[Barnacles]

Hi All,

We are building an extension to our kitchen and as part of the works we are looking to relocate the CU, electric meter, incoming supply fuse etc. I would like to install a new recessed meter box into the wall of our boiler room (it's an oil fired boiler) which is constucted of a single skin of 4" solid blocks. The CU has a new location in the house but everything else will be in the new meter box (including a KMF switch as CU will be some distance away from the meter). Our DNO have said that we can locate the new meter box anywhere on the gable end of our house that suits our works.

 

Firstly is it acceptable to install a recessed box into a 4" wall as the back of the box will be stuck right though the wall? Secondly, is there any problem with being relatively close to the boiler. I've searched the web and can't find any reference to oil boiler and/or flue distance to meter box. Is there a regulation for it?

 

The meter box would be approximately 300mm horizontally away from the flue and there would be about 150mm between the back of the meter box and the case of the boiler.

 

Any advice would be much appreciated.
