Those two copper pipes which go nowhere look shiny and new. I'd want to cap them off properly.

I agree that the water supply post-dates the electricity supply, but their proximity is not dangerous in itself.

Assuming that the incoming supply is PILC (paper insulated lead sheathed cable) that BS 951 clamp for the earthing conductor is inappropriate.

The equipment is nothing to do with National Grid - it is the responsibility of your Distribution Network Operator, which depends upon where you live.

You could ask the DNO to provide information i.a.w. Regulation 28 of ESQCR 2003. Then they would have to come out and have a look (unless they already know the answers).

"28.  A distributor shall provide, in respect of any existing or proposed consumer’s installation which is connected or is to be connected to his network, to any person who can show a reasonable cause for requiring the information, a written statement of—

(a)the maximum prospective short circuit current at the supply terminals;

(b)for low voltage connections, the maximum earth loop impedance of the earth fault path outside the installation;

(c)the type and rating of the distributor’s protective device or devices nearest to the supply terminals;

(d)the type of earthing system applicable to the connection; and

(e)the information specified in regulation 27(1),

which apply, or will apply, to that installation."

Thank you Chris, I will ask them to provide that information. I really just want the connections brought to the outside wall - they are currently in the downstairs loo!

Is there any restriction on how close the electric supply can be to the mains gas?

UKPN wanted 600mm separation electricity from gas a few years ago.  I dont know if this is a DNO standard or a local rule.

The meter changer's hand book says to raise a problem report if it is within 150mm - see here https://www.eusr.co.uk/wp-content/uploads/2020/01/Guidance-for-Electricity-Gas-Meter-Installation-Customer-Facing-Issues.pdf

pages 37 and 38....

Examples include
• Electricity meter is installed close to gas pipes or gas equipment (i.e. less than required
150mm separation).
• Meters currently installed within, or close to hazardous environments.
• Meter position which may be subjected to current or future damage.
• The current position of the meter could mean that work activity currently being undertaken
on site could impact on the future access to the meter or safety of the installed equipment.
Actions
In order to complete the work remedial action may need to be taken by the consumer / landlord or
housing authority to allow adequate access.
