Chargemaster Unveils Multiple UK Tariffs for Electric Car Charging

As it promised a few weeks back, UK firm Chargemaster has just quietly unveiled details of how much it will charge electric vehicle owners to use its Polar EV charging network from April 1.  With two different monthly tariffs plus a more expensive Pay-As-You-Go option, Chargemaster says existing Polar customers — who currently pay £10 per year for unlimited charging and whose memberships will automatically expire on March 31 — will have to choose to let their membership expire or to sign up for one of the new services.

With charges for a Type 2 public charging station costing up to £2.50 per hour, and rapid charging costing £8.50 for half an hour however, many EV owners are already fearful that the fees outlined by Chargemaster are too expensive, too soon.

Here at Transport Evolved, we’ve spent some time drilling down to figure out exactly what’s included in each tariff, as well as what we think it will mean for current and future EV drivers.

Polar Economy Plus

Chargemaster says the Economy Plus tariff will cost drivers £12 per month if paid by direct debit, and include twenty ‘charging credits’ which can be used on the network over the course of each month.

  • An hour of charging at a Polar Network 13 amp (UK domestic outlet) point will cost one credit. That’s a theoretical power draw of just under 3 kilowatts per hour, but since most production electric cars we know restrict 13-amp charging to 10 amps, that’s nearer to 2.3 kilowatts, or between 5 and 10 miles per hour.
  • An hour of charging at a Polar Network type 2 (7 pin Mennekes) point will cost two credits. Because the Type 2 charging standard does cover a range of power levels, that could equate to a power level of anywhere from 3.3 kilowatts or 7 kilowatts single phase all the way up to 22 kilowatts three phase. In our experience however, most Polar points are either 3.3 kilowatts or 7 kilowatts, translating to a usable range increase of between 10 and 20 miles per hour, depending on the car you have.
  • A half hour of charging at a Rapid DC or rapid AC unit will cost ten credits. On many EVs, this will be enough to theoretically charge from empty to 80 percent full, but in our experience 30 minutes will normally charge from 20 percent to 80 percent full in that time. A fully depleted battery pack will require nearer 45 minutes.

Once you’ve used up your ‘credits’ Chargemaster says you’ll still be able to charge, but it will levy an additional £0.95 per hour (or part) for 13 amp domestic charging points, £1.90 per hour (or part) for Type 2 charging stations, and £6 per 30 minutes (or part) for rapid charging.

It’s worth noting too that this particular tariff seems very similar to BMW’s own ‘mobility’ package for BMW i3 owners, which offers ‘free’ charging access for subscribers to its service. It’s also worth noting that Chargemaster is the chosen provider for this service.

    i think some of these fees are very high…

    i would assume there will be a massive dip in the amount of usuage becuase of this. i know for sure that i will only charge when i have to, rather than as a habbit like i have done so previously.



    I use Chargemaster points quite a bit locally at Waitrose etc. These are also SourceLondon, so I will simply use my SourceLondon card until that runs out in June this year. After that, I will probably not use these at all. For most trips I will be able to charge at home or will use the Ecotricity fast chargers.



    They lost the plot. Far too expensive.



    To compare, here is a little info on electric car charging tariffs in Denmark. We have only 2 electricity networks for charging EV’s. One of them (e-on) currently doesn’t support charging for the Zoe, so that leaves only one, which is a company called ‘Clever’. They have a decent network of 22kw chargers spread over most of the country. We currently have no 43Kw chargers in denmark. ‘Clever’ has a model with a monthly fee. You pay £11/ month. And the charging cost is £0,40/ Kwh. They also have a model wih no monthly fee, the charging cost is then £0,61/ Kwh. That means a theoretical full charge cost is £8,8 with the monthly fee model, and £ 13,42 with the ‘pay as you go’ model.

    daymolton, that sounds pretty expensive. I guess we should be very grateful for the Ecotricity network of free 43kW chargers.



    Thus far we haven’t actually used public charge points very much at all,so probably it will not make much difference to us. I suspect we will probably register for the £20 annual charge so that we are able to use the points if we absolutely need to. However we certainly will cease plugging in for a top up charge as we have been doing. We have registered with the Ecotricity network, but never seem to drive anywhere near where they are, so currently it appears the only charge points near our travels are, or will be, pricy to use. (Source London points also have announced they are likely to be charging after June, and I guess may charge similar amounts.)



    Well having noticed that the recent e-mail from Chargemaster which outlines their new tariffs, mentioned that either option allowed free charging at points which were free, I contacted them to ask when their map would show which points these are. The response said that by the end of the following day, the map should have been updated to indicate this. I have allowed a few days to pass since then, but if you view the Live Map on the Chargemaster site and click on various points, you should see that some points now have prices indicated under the socket description. The good news is that, if one assumes they have completely updated the map by now, the free points outnumber the others! It seems from my experimenting, that those within a supermarket car park will remain free, whereas Little Chef points will cost you, as will some in NCP car parks. Some towns seem to have been a bit unlucky. If you live in Brighton for example, it seems that all the points in town will cost you, but you can wander slightly further afield and visit the Asda for free charging!

    One assumes that you will still have to have subscribed to Chargemaster one way or another and that the payg app will not enable you to use the free points, for free! And of course, I am sure that they are at liberty to add charges to these points in the future, as they please. However, I suspect that for the foreseeable future, the supermarkets will be loath to allow charging points to cost their customers to use them, in case that is a disincentive to visit.



    If that is correct, woodlee, that is a ray of light. It does make sense that this would be the case. The only Chargemaster/Polar charger I have used was in an Asda which did get some business from me as I charged the car. It would make very little sense for supermarkets to have expensive charging stations on their grounds, as you say. I was going to abandon the Polar network card I had, but I might consider keeping it now.



    In fact I have had another e-mail from Chargemaster this evening, saying “the website is now showing the charges for every post as from 01/04/14. Click on the post and it will advise of the cost. If it states £0.00, then it’s free still.”
