DVLA records about 5,311 privately kept plug-in vehicles across Bedford borough at the end of June 2026, up from about 3,627 a year earlier. That is a rise of about 46% in a year, on our arithmetic, and it counts only cars registered to private keepers, so company fleets do not inflate it. More Bedford households are now asking whether the roof can charge the car. Sometimes it can, at least in part. This guide sets out what a Bedford roof can realistically give a car through the year, and how panels, a battery and a charger fit together. For the roof itself, planning and the Bedford grant position, see our page on solar panels in Bedford.
The figures count plug-in vehicles of all kinds, battery-electric and plug-in hybrid, across the whole borough, not just the town.
What a Bedford roof can give a car
PVGIS 5.3, the European Commission’s solar calculator, puts a 4 kWp south-facing array at Bedford’s town-centre point at about 3,999 kWh a year. The months tell the real story.
| Month | PVGIS output, 4 kWp | Average per day (our arithmetic) |
|---|---|---|
| June | about 477 kWh | about 16 kWh |
| July | about 482 kWh | about 15.5 kWh |
| December | about 141 kWh | about 4.5 kWh |
| January | about 158 kWh | about 5 kWh |
A 7.4 kW home charger uses about 7.4 kWh in an hour of charging. So on an average June day, after the house has taken what it needs, an unshaded array may cover a useful top-up; on an average December day it covers less than an hour’s charging in total. That is the honest shape of solar EV charging in Bedford: a strong summer contribution, a small winter one. Ofgem’s typical domestic consumption value of 2,500 kWh a year, from 1 July 2026, is a reminder that the house competes for the same output.
Panels, battery and charger: which order
Panels first, if the car is home in the day. Some chargers can be set to use surplus solar while the car is plugged in, so check for that feature when you choose one. Every new home chargepoint sold in Great Britain has had to be smart since 30 June 2022, but smart charging and solar charging are not the same thing.
A battery, if the car is out in the day. If the car leaves in the morning and returns at dusk, the surplus has nowhere to go but the grid. A home battery can hold some of it for the evening. The Energy Saving Trust says a typical home system might be 10 kWh, far smaller than a car’s battery, so it tops up rather than fills. Our page on battery storage in Bedford covers sizing.
The charger, on its own merits. In winter most charging comes from the grid, ideally overnight on an off-peak tariff. The charger is worth having whatever the roof does.
The fuse and the network
A 7.4 kW charger draws 32 A continuously. Most homes have a 60 A, 80 A or 100 A main fuse, and load management, a current sensor on the incoming supply that slows the charger when the house is busy, usually avoids an upgrade. Our guide on whether your fuse will take a 7 kW EV charger goes through it.
Bedford is on UK Power Networks’ network, and the installer notifies UKPN of every new chargepoint. UKPN says it can upgrade a main fuse from 30 or 60 A to 80 or 100 A, and a looped supply shared with a neighbour has to be re-planned with both households and may carry a charge. Adding panels and a battery as well often takes the generation side over 3.68 kW, which means a G99 approval before work starts rather than a G98 notification after.
VAT and grants differ for each piece
This catches people out. HMRC zero-rates residential solar panels and batteries until 31 March 2027, then 5% from 1 April 2027. A home EV charger is not on the energy-saving materials list, so its installation is standard-rated at 20%.
Grants differ too. OZEV’s chargepoint grant, raised from £350 to £500 per socket on 1 April 2026, covers renters and people who own and live in flats with private off-street or allocated parking, at 75% of the cost up to £500, claimed through an OZEV-authorised installer. Owner-occupiers of houses get no chargepoint grant; that scheme closed in April 2022. Our post on who qualifies for the EV chargepoint grant has the detail.
Flats and rented homes in central Bedford
Central Bedford has more of the homes the grant targets than the borough as a whole. In the built-up area, flats, maisonettes and apartments make up 28.9% of households and 25.2% rent privately, while across Bedford Borough 62.7% own their home. If you rent, the landlord decides on the charger and any panels. If you own a flat, the freeholder’s consent comes first, and the roof of a block is rarely yours to use.
