I’m not going to dispute what the prices showing on ZapMap are shown to be, however I’ve just downloaded the Shell Ubitricity App and it is indicating that the price per kWH is 54 pence, plus a 35 pence connection fee for all the 5kW and 7kW chargers in my area. Most of them (and possibly all) are lamppost chargers. There aren’t any (Shell Ubitricity) fast chargers nearby, the closest ones are near the Duke of Sussex at the MFG petrol station are 81 pence per kWH.Now it could be that my app is showing me the wrong price, but I’d be a little surprised if that was the case. I’ll charge my hybrid sometime and see what the true price turns out to be and if it’s really 76pence per kWH then I’ll report that back.The advantages of lamp post chargers (as I see them) are that they can be cheaper, you are likely to be able to not have to drive too far from near where you live to access one, and they are easier to install without having upgrade the existing power grid.The disadvantages are speed, reliability and sometimes availability.I don’t know about Hounslow and what has been proposed as regards parking near any proposed new chargers, lamp post or otherwise.In LBHF, the lamppost chargers that I tend to use don’t have any additional parking restrictions near them compared to the rest of the same road.That means that you might find that you can’t use a particular lamp post chargers either because you can’t park close enough because of other vehicles or because although you can park close enough there is a vehicle that has already connected up. There is no requirement to move a car once charging has been completed. There are some bays in LBHF dedicated to electric cars where you aren’t meant to park if you’re not actively charging.The comment I would make about installing fast chargers on residential roads is that it will cost more, not only for the charger but more than likely to provide the power that goes to the fast charger. This being the case, to recoup the investment you will need to charge more - that’s fine, you are paying a higher price for a premium service, but you will also need to make that charger accessible to anyone who wants to charge their car, when it’s not already actively charging a car.That means loss of parking space in residential roads where fast chargers are installed. Maybe not 24 hours a day, but certainly when the CPZ is active.If residents are happy with that, fine, but it is an issue that needs to be acknowledged. The question is, who do you ask about what they want to happen? All the residents in the road? Or all the CPZ permit holders in the road? Or all the residents in the whole CPZ?

Andrew, the issue isn't the where. It's the how.There was a recent council initiative to adopt crossing the pavements safely with cables plugged in to a charge point mounted on a private residence. This required the installation of a channel flush with the pavement to bury the cable during a charge. All, I believe, at the homeowner's expense.  Parking wouldn't need to be restricted. And I'd like to think that your neighbors know who you are and would happily accommodate your parking to charge if need be. Granted this would work best on a street with mostly private residences. On my street we know who's car is whose and everyone falls into a defacto system of sorts.Meanwhile, if we join up the thinking, take a look at the pavements. They're often in dire need of repair. So if the council replaced paving stones and installed proper protected conduits it would be a win/win. A better investment of public funds in my opinion than spending anything on woefully inadequate lamppost chargers. The problem with the current proposal for installing conduits/raceways is there seems to be no ability for quality control of the works needed to install. That's just a liability disaster waiting to happen.Of course you also could install charge points in parking new parking facilities. The entire structure could be a charge center. Did that happen in Brentford? Probably not. So that's nine stories of parking without the ability to charge (of course Guy Lambert can weigh in with details - as a Green candidate he approved that parking facility). Did that happen in Hammersmith? Yes. Could it happen in Chiswick? Yes. If you require developers to provide bike racks, no reason you can't require developers who provide parking to install charge points.It would require ironing out how to keep them operational. The facility in Hammersmith stopped providing the service about the time there was a spike in electricity rates. There are very few points that remain useable. A huge loss of perfectly viable infrastructure.
