Electric vehicle charging requirements for a residential scheme
Charge point provision for new homes comes from Approved Document S and is enforced by building control, but the parking layout, substation space and local plan percentages are planning decisions.
Every new dwelling with an associated parking space needs its own electric vehicle charge point, and that requirement comes from the Building Regulations rather than from planning policy. Approved Document S took effect on 15 June 2022 and sets the electric vehicle charging requirement for residential development in England, enforced through building control. Planning still matters, because local plan policies frequently ask for more than Approved Document S does, and a parking layout that cannot physically take the cabling is a planning problem long before it becomes a building control one.
The split confuses developers more than it should. Building control checks whether the charge points were installed. The planning permission decides how many spaces exist, where they sit and whether the scheme committed to anything above the national minimum. Get the planning layout wrong and no amount of later negotiation fixes it.
Where the requirement comes from and who enforces it
The Building Regulations 2010 were amended in 2021 to add Part S, with the technical detail in Approved Document S. It applies to new residential buildings, residential buildings undergoing major renovation, mixed use buildings and non-residential buildings, each with its own rule.
Enforcement runs through the building control body on a completion certificate, not through the planning case officer. That matters for anyone assuming a planning condition can be met by pointing at Part S compliance, or the reverse. A condition requiring 20 per cent active provision is a planning obligation in its own right and has to be discharged on its own terms.
Active and passive provision explained
Active provision means an installed, working charge point. Passive provision means the cable route, duct, electrical capacity and distribution board space to allow a charge point to be fitted later without opening up the surfacing again.
Passive provision costs little at construction and a great deal to retrofit, which is why policies lean on it so heavily. The specification matters more than the label: a duct that terminates at a wall with no spare way in the consumer unit and no capacity reserved at the supply is not passive provision in any useful sense, and a reviewing officer who has seen a few schemes will ask for the single line diagram.
Dwellings with and without associated parking
Approved Document S turns on whether a dwelling has a parking space associated with it.
| Situation | What Approved Document S requires |
|---|---|
| New dwelling with one associated parking space | One charge point for that dwelling |
| New dwellings where spaces outnumber dwellings | A charge point per dwelling, plus cable routes to the remaining spaces |
| New residential building with communal parking and fewer spaces than dwellings | A charge point per space, plus cable routes where capacity allows |
| Residential building undergoing major renovation with more than ten spaces | A charge point per dwelling with an associated space, plus cable routes to every remaining space |
A dwelling with no parking space at all triggers no requirement under Part S. That is not a reason to design parking out and claim a benefit, because local plan policy on car-free development usually brings its own obligations for cycle parking and car club provision.
Minimum power output for a residential charge point is 7 kW, and the point must meet the applicable product and smart charging standards. Under the Electric Vehicles (Smart Charge Points) Regulations 2021, charge points sold for private use have to have smart functionality by default.
Communal car parks and the proportion rule
Communal parking for a block of flats is where schemes come unstuck. The requirement attaches to spaces rather than to front doors, and the electrical design has to serve a bank of points from one supply rather than a point per meter.
Three things to settle at planning stage. The location of the substation or supply cupboard, because retrofitting one into a landscaped courtyard is a planning application of its own. The route of the main containment, because it dictates where columns and drainage can go. And the management arrangement, because a block with charge points and no agreed billing method ends up with points that nobody switches on.
Where the scheme is in London, the London Plan's parking policies ask for active provision at a stated proportion of residential spaces with passive provision for the rest, which is more demanding than Part S in most layouts. Check the borough's own standards as well, since several go further.
Electrical capacity, substations and the supply constraint
The supply is the real constraint. A distribution network operator quotation for a new or upgraded connection can take weeks to obtain and months to deliver, and on constrained networks the reinforcement cost is the number that kills the specification.
Approved Document S recognises this with a cost cap: where the cost of connecting to the existing electricity supply exceeds £3,600 per charge point, the requirement is reduced to the number of charge points that can be installed within that cap, with the shortfall evidenced. The evidence has to be a real quotation, not an estimate, and building control will ask to see it.
Get the DNO quotation early, because it changes the planning drawings. A scheme that needs a new substation has to find 3 metres by 4 metres of accessible, flood-free land with vehicular access for a transformer delivery, and the place that works is rarely the place left over at the end of the layout. The same early-engagement logic applies to safeguarding a future heat network connection, where the plant space has to be reserved before the ground floor plan is fixed.
Interaction with local plan parking standards
This is where planning and building control pull against each other. Many adopted plans cap residential parking to encourage sustainable travel, while also requiring a proportion of the remaining spaces to be actively charged. Fewer spaces and a fixed percentage can produce a single active point for a scheme of 20 flats, which satisfies the letter of the policy and nothing else.
Read the two policies together and say in the submission what the arithmetic produces. Where the result is obviously thin, offer more active provision rather than inviting a committee to notice the gap. The broader policy picture, including how authorities have drafted these standards, is covered in the review of electric vehicle charging standards in local plans, and the relationship between the national standard and local policy in the note on Approved Document S and local policy.
An Energy Statement is the natural home for the charging strategy on a major application, because the load from charging interacts with heat pump demand and any on-site generation. Keep the charging section short and numerical: spaces, active points, passive routes, assumed diversified load and the supply capacity secured.
Illustrative example. A 48 flat scheme with 24 communal spaces, a policy requiring 20 per cent active provision and a DNO quotation showing reinforcement at a cost that exceeds the Part S cap for more than seven points. The planning answer was five active points at 7 kW with full passive provision to all 24 spaces, a load management scheme across the bank, and a reserved area for a second supply. The figures are illustrative, but the sequence is the one that works: quotation first, then layout, then policy compliance statement.
Conditions and the evidence expected at completion
Planning conditions on charging provision usually require details before above ground works and evidence before first occupation. Both are easy to satisfy and easy to forget.
- Submit the layout plan marking active and passive spaces, with the charge point specification and power output.
- Submit the single line diagram or supply capacity confirmation from the DNO.
- Provide the management arrangement for communal points, including who bills the user.
- On completion, provide installation certificates and photographs for the discharge of condition application.
Where a scheme relies on the Part S cost cap, put the DNO quotation in the planning file as well as the building control file. Councils have started asking why a permission that promised active provision delivered less, and the answer is far easier to give when the evidence was lodged at the time. A short note in the Sustainability Statement recording the position avoids an argument at discharge stage two years later.

Frequently asked questions
Does every new home need an electric vehicle charge point?
Every new dwelling with an associated parking space does, under Approved Document S, which took effect on 15 June 2022. A dwelling with no parking space of its own triggers no requirement under Part S. Where spaces outnumber dwellings, cable routes must be provided to the remaining spaces.
What is the difference between active and passive provision?
Active provision is an installed, working charge point. Passive provision is the cable route, duct, spare capacity at the supply and distribution board space needed to add a point later without excavating the surfacing. Passive provision is only meaningful if the electrical capacity has been reserved in the design.
Can the cost of a new connection reduce the requirement?
Yes. Approved Document S applies a cost cap of £3,600 per charge point for connecting to the existing electricity supply. Above that, the requirement falls to the number of points installable within the cap, evidenced by a real distribution network operator quotation rather than an estimate. Keep that quotation in the planning file too.
Who enforces the charge point requirement?
The building control body, through the completion process, not the planning case officer. A separate planning condition requiring a stated proportion of active spaces is a planning obligation in its own right and has to be discharged on its own terms, with layout plans, specifications and installation evidence.
Do local plans ask for more than Approved Document S?
Often, yes. The London Plan sets a proportion of residential spaces for active provision with passive provision for the remainder, and several boroughs and authorities outside London go further. Read the parking cap and the charging percentage together, because a low space count can make the percentage meaningless.
