Hi all,

I've been looking at EV cars for a while now and with a new company car scheme opening up at work I've taken the plunge and ordered a VW ID.3 Pro. Always one to do things the wrong way around, I've now started looking at how I could go about charging the bloody thing.

I have a couple of issues here. Firstly, my parking space is not directly attached to my house, its on the other side of my garden, and the other side of my neighbours drive, next to my garage. In the below image, the red arrow points to my electricity meter and supply (mounted to the wall outside the from door). The blue arrow points to my garage (blue door), and the green box is my neighbours parking space. The grass is my garden (which i need to mow).

So the good news (I hope) is that the garage already has an electricity supply, which works fine. So my first question is, does this seem suitable for the "granny charger" as a bare minimum?

The socket on the wall in the garage:

Finally, I have read on the forums about looped services, and it looks like I may have one, being in a four house cul-de-sac with the below in my meter box:

The side of the bottom box which I think shows a 100amp service (but someone has scratched it off, unhelpfully!:

The fusebox in the house was installed after I moved in as we did not have RCD protection when we bought the house last year. The socket in the garage was there previously. I am interested that the socket in the garage states 30amps, does that mean I may be able to draw a fairly quick charge from the socket, if I upgrade the breaker in the fusebox to match?

So, to summarise, my questions are:
Will I be able to plug in a granny charger into the garage socket with no issues?
Will I be able to get a wallbox installed at my property without considerable expense (such as digging up the neighbours driveway)?
What sort of price do you think I could be looking at?
Does the looped service make a difference and what can I do about it?
What charging time could I be looking at with and without a wallbox with a 58 kwh battery VW ID.3?

If it matters, my DNO is Western Power Distribution and I am based near Birmingham. Any recommendations on an installer that could take a look and/or provide a quote would be really helpful.

Thanks to all and everyone who have any ideas or suggestions!

Hi, you should be ok to use the granny charger.
I would suggest contacting the DNO about the looped supply and getting a load check done.
I would get a quote for the install from a couple of places but I did read somewhere that you can not get the grant for wierd installations.

Thanks Harry, I'm glad I'll be able to use the granny charger as a minimum but I'm keen to get a 7kw wall box going this side of the grant deadline this March. I have been trying to get quotes for the install but a lot of the websites don't seem to want to come and look at a non-standard install. Struggling to get someone to actually come and give me a quote!

I'd imagine the 100A label has been scratched off because a lower value fuse has been fitted.
There will be some way to get a proper chargepoint installed, it may require load-limiting if the supply is limited. As regards location, you just need to figure out a cable run from where you want it to your consumer unit or meter box.

To run a 7kw charger you really need a new cable to your garage.

What is to the right of the photo, and who owns it? Is there an above ground route from your meter box to your garage? IE - from left to right from the meter box in your photo, then across to the back of the garage block and into the back of your garage?

Equally there are methods of getting a cable under a drive without digging it up (using a mole).

Going to be hassle getting a proper charger installed unfortunately.

The supply to the garage doesn't look adequate for a dedicated charger and running a new cable there from your meter will require excavation.

Even using a mole this will be expensive thats before you get into easements for the new cable etc.

If it's a looped supply you are then into if there is the capacity to run a dedicated charger safely with the existing load of the four properties. What if all four properties install a charger in this way it will be required eventually and you are setting a precedent

The first thing I would do is check legals who owns the land between your meter and garage do you have an easement for electricity supply and can you excavate to put a new cable in for the garage.

Next will the looped supply you have there support a dedicated charger. The problem is these houses clearly were not built with this sort of installation in mind, in this case made more difficult be the supply and fact you parking space is not joined to your property.

I can see why you are struggling to get quotes. The issues are not insurmountable but there are Labour shortages and anything that is difficult / non standard most people will not touch when they can pick and choose jobs.

You are aware you have to actually own an EV before you apply for the grant btw ?

What's the route the current garage power supply takes? Can you easily run a new cable along that route? You would want to take a cable from the meter box to the garage, not from the house consumer unit. It doesn't look too difficult to be honest. When you're getting quotes consider getting the cable run separately, or even doing that yourself, as it will likely be much cheaper.

So, to summarise, my questions are:
  1. Will I be able to plug in a granny charger into the garage socket with no issues?
  2. Will I be able to get a wallbox installed at my property without considerable expense (such as digging up the neighbours driveway)?
  3. What sort of price do you think I could be looking at?
  4. Does the looped service make a difference and what can I do about it?
  5. What charging time could I be looking at with and without a wallbox with a 58 kwh battery VW ID.3?
  1. Sadly it is not guaranteed. There are endless threads on here about the safety of granny chargers and how they should be used in "emergencies" only. A few issues - it is quite common for the live pin of the plug to overheat in the socket, so if you do use one check it regularly. Secondly the RCD arrangements are wrong for EVSE wiring - it will cover some scenarios but not all. Finally, there is a 16A MCB on the circuit but no indication what else is on the circuit - for example I presume that the cable going up from the socket fees the lights. You need to ensure that the total current including the 10A of the granny charger is within tolerances.
  2. It is hard to see whether you have access to run a cable behind the neighbours garage to access your garage without going under the drive. For example if there is a fence behind the garage block that you are responsible for you might be able to clip it to that. Alternatively you might be able to be creative with an overhead wire to the garage from your property. Going under the drive requires permission from your neighbour, and in theory from their mortgage holder.
  3. No idea. It depends how hard it is to get the cable there - it could be a standard install or require just a few metres more cable, or some specialist groundworks.
  4. There's lots of threads on looped services and unlooping them. The bottom line is whether you actually need to or not. Get a competent local charge point installer out and they can contact your DNO to find out and advise on how much headroom there is on your current supply and loading. It may be that you need a load limiting device fitted that dynamically turns down the current on your charge point as you draw current on other devices. These work well and often rarely come into play as you may never get near to the limits other than in theory.
  5. Depends how many miles you do between charges! One hour on a granny lead adds about 8 miles, on a 32A charge point around 28 miles. The first and last parts of the battery are slower to charge, so generally people quote a figure for a 20% to 80% charge which gives about 18 hours on a granny charger and 5 hours on a 32A charge point. So the real problem only comes if you do a long journey and arrive home empty and need to leave home after only a quick 8 hours of kip with a full battery for another long journey - only the 32A charge point can do that for you. But if you just have a typical 25 miles roundtrip commute and similar at the weekend a granny charger can do that on 3 hours per night. You need to look at how you use your car and how rare the first scenario is and whether the occasional use of a Rapid charger gets around those rare events.
Good luck and fill in some of the missing information.
