Smart charge point regulations, explained

What the regulations require

The Electric Vehicles (Smart Charge Points) Regulations 2021 came into force on 30 June 2022. From that date, any new domestic or workplace charge point has to be smart. This is not a premium feature or a manufacturer's marketing line. It is a legal minimum, and it is why every unit you can buy today behaves in broadly the same way out of the box.

• The charge point must be smart. It has to be capable of sending and receiving information, and of responding to a charging schedule rather than simply passing current the moment a car is plugged in.
• It must arrive pre-configured with default off-peak charging hours. The unit is set to charge outside peak periods before you ever open the app.
• Those default hours must be adjustable. You can change them, and you can charge whenever you want. The default is a starting position, not a lock.
• It must apply a randomised delay of up to ten minutes. The delay is applied at the start of a charging schedule, and again after an interruption.

Default off-peak hours, and how to change them

Your charger comes out of the box already scheduled to charge at off-peak times, and you are free to move that schedule. The reason to leave it broadly where it is comes down to money rather than compliance: overnight EV rates currently sit at roughly 6.99p to 9p per kWh against a capped average unit rate of 26.11p, a discount of around 65 to 73 per cent. Which windows apply depends on the tariff you are on, and our tariff guidance tracks those as they move.

Rates and windows checked 3 August 2026. All are region dependent and conditional on a working smart meter. Confirm the current position with the supplier before switching.

The randomised delay, and the ten minutes of nothing

The delay is the part that generates the most support calls. You plug in at 23:30, the schedule says charge, and nothing happens for several minutes. The unit is not faulty. It is applying the randomised delay the regulations require, capped at ten minutes, before it starts drawing current.

The purpose is coordination. If every charge point on a street, a town or a national tariff started at exactly 00:00:00, the grid would take a step change in demand at the same instant every night. Spreading the starts across a random window of up to ten minutes smooths that. The delay applies again after an interruption, so a brief power cut mid charge means another short pause before the session resumes rather than an instant restart. It does not reduce the energy delivered, only the moment the session begins.

Who is allowed to fit one

Charger installation is notifiable electrical work. It has to be carried out by a registered competent person under a scheme such as NICEIC or NAPIT, or notified to your local building control directly. You should finish the job holding an electrical installation certificate and confirmation that the notification was made. Skipping that paperwork is the sort of thing that surfaces at the point of sale or on an insurance claim, years later.

Separately, your Distribution Network Operator has to know. Most domestic single phase chargers follow a connect-and-notify route, where the installer fits the unit and notifies the DNO afterwards, typically within 28 days. County pages on this site name the network operator for your area and carry a local calculator for running the numbers on your own usage, and you can reach yours from the coverage map.

New builds, flats and Part S

Part S of the Building Regulations has applied in England since 15 June 2022. A new home with associated parking has to be built with an EV charge point of at least 7kW, or with a cable route where a charge point is not feasible. Blocks of flats with shared parking need charge points across a minimum share of the spaces, plus cable routes for the rest. If you are buying new and the plot has parking, the charge point provision is a question for the developer rather than an aftermarket job.

What the rules leave to you

1. Which charger you buy. Smart is the floor, not the ceiling. Tariff integration, solar surplus tracking and cable format vary widely between units, and none of that is mandated. Our EV charging guidance covers the differences that actually change your bill.
2. Which tariff you sit on. The regulations set the charger's default behaviour, not your rate. A whole home off-peak tariff and an EV-only add-on produce very different bills for the same car.
3. Whether you charge from your own generation. Surplus-aware charging from solar is a manufacturer feature, not a legal requirement, and it interacts with a home battery competing for the same surplus.
4. Whether a grant applies. The chargepoint grant covers renters, flat owners and landlords, plus households with only on-street parking using an approved cross-pavement solution. The cap rose from £350 to £500 per socket on 1 April 2026, and an approved installation team is a condition of claiming it.

Clearline gives independent guidance and does not install. All installation work, certification, building control notification and DNO notification are carried out by an MCS-certified installation team for your area.
