Outdoor meter box

I note that the outdoor meter cubicle, sometimes referred to as a Pirelli box, is fast becoming a location for a small consumer unit to provide a supply to an EV charger in domestic premises. As I understand it, the box belongs to the householder so it would seem that providing DNO equipment is not compromised, there is no reason why this cannot be done?
  • A few perils here. 

    Firstly IIRC it is a condition of the supply that the box is for DNO equipment only, perhaps not an issue but that will have been agreed when the supply was provided. 

    Secondly, a small CU will also require a pair of Henley blocks or similar and space to connect the tails.  It can be done neatly but it will occupy more space. 

    Thirdly in the future meter upgrades, time switches, tele switches and associated auxiliary fuses may not fit in the space that is left and this may restrict supply options going forward.  Less of a risk these days provided there is space for a smart meter (and any antenna required).


    That said i expect we will see plenty of such installations.

    Is the meter box designed to be opened twice daily and are the DNO contents suitably IP rated?


    If the householder can spend £25k+ on an electric vehicle, I don't see a problem them spending £50 and use of a chisel to install another meter box nearby.

  • If someone is spending £25K+ on an EV they should not be penny pinching on having an EV charger installed at home and be prepared to pay enough to have a future proof supply and a charger that will charge their own vehicles and their guests now and in ten years time when they may have replaced the car, but not the charger.


    No one should have an issue with paying at least £1k for installing an EV charger at home if required.
  • At a minimum there needs to be space for the supplier to install an additional check meter in case case of an meter accuracy dispute.

    But of course if we want EVs not just as an elite show off thing but also to reach mere mortals, for whom 25K is a large chunk of a years wages, if not all of it,  it is not a reasonable price level at all.

    I do not know if you are in the habit of buying brand new vehicles, but I certainly am not, and I do not consider myself badly paid.

    At the ten year old car end of the market, an extra £k  is a large fraction of the vehicle cost and may be the decider not to go electric at all.

    longer term, if this is to displace petrol, it needs to be a lot simpler and a lot cheaper. And we need to know what to do with ten year old battery packs as well.

    Isn't it just an additional CU for the EV that's in the meter box - not the charge point itself?

    box belongs to the householder

    True, but the householder will usually have a contract with the supplier - which typically means they've agreed to leave the interior of the box free for DNO/supplier equipment (even if it was only in very small print in the current connection conditions on a web site somewhere).

  • On my travels around England and Wales I have only seen one specialist second hand EV dealer.


    But there’s lots of dealers selling high powered upmarket petrol and diesel cars that a now getting quite old, but are in immaculate condition for £6k to £10k, slap dome cheap personalised plates on them and they look very impressive, so I’m not really sure there is much of a secondhand EV market yet.


    Installation of an EV charger at home is an investment, not an expense unlike the fuel or electricity used to run a car you will still have the charger next week, indeed you will still have it for many years to come.
  • If the consumer unit is rated as IP65 does it need to be inside the meter box, why can’t it just be on the external wall next to the box?
