Dwellings — EV Charging Installation Practice

Sample questions

1. 01An electrician became OZEV-authorised on 1 March. A customer asks him to claim a grant for a charge point he installed for them on 10 February. What is the position?

   • AHe can claim it once his scheme confirms the work
   • BHe can claim it, as long as it is within the same year
   • CHe can claim it if the DNO was notified in 28 days
   • DNo; only work done after authorisation is eligible

   Why: GOV.UK states that only installations carried out after the date of authorisation are eligible for OZEV grant funding (page updated 1 April 2026). Scheme sign-off and DNO notification are duties in their own right, but neither makes earlier work claimable.

2. 02A new detached house in England has a private drive with two parking spaces. The connection cost per charge point is under £3,600. What does Approved Document S expect?

   • AOne charge point, as there is one dwelling
   • BNothing, as Part S only covers blocks of flats
   • CTwo charge points, one for each parking space
   • DCable routes only, with no charge point at all

   Why: ADS paragraph 1.1 sets the minimum number of associated spaces with access to a charge point as either the number of spaces or the number of dwellings the parking serves, and paragraph 1.3 only adds cable routes for spare spaces where there are more than 10 spaces. One dwelling with two spaces needs one charge point. Part S covers new dwellings of every kind.

3. 03A new block of 20 flats in England has 30 associated outdoor parking spaces, with connection costs under the cap. What does Approved Document S expect?

   • A20 charge points, and no cable routes at all
   • B30 charge points, one in every parking space
   • C1 charge point, plus cable routes for 6 spaces
   • D20 charge points, plus cable routes for 10 spaces

   Why: Paragraph 1.1 sets the minimum at the number of dwellings the car park serves, here 20. Because there are more than 10 spaces and more spaces than dwellings, paragraph 1.3 then requires cable routes for every space without a charge point, the remaining 10. One point plus one in five is the non-residential pattern in paragraph 3.1.
