Regulation 44J: Minimum standards of an electric vehicle charge point

Regulation

Minimum standards of an electric vehicle charge point

44J. (1) For the purposes of this Part and Part S of Schedule 1, an electric vehicle charge point must meet the following minimum standards.

(2) It must be capable of providing a reasonable power output for each parking space for which it is intended to be used.

(3) It must be run on a dedicated circuit.

(4) It must be compatible with all vehicles which may require access to it.

Interpretation of this Part and Part S of Schedule 1

“cable route” means a safe, unobstructed route from the power supply to the envisaged electric vehicle charge point
location, for electrical cabling to be installed in the future.

NOTE: Where the building control body is an approved inspector, see regulation 8 of the Building (Approved Inspectors etc.) Regulations 2010 (as amended).

Intention

In the Secretary of State’s view, regulation 44J will be met if the electric vehicle charge points installed to meet any of the requirements S1 to S6 meet paragraph 6.2.

Cable routes installed to meet any of the requirements S1 to S6 should meet paragraphs 6.3 to 6.12.

NOTE: Paragraphs 6.3 to 6.6 provide guidance on the location of electric vehicle charge points and future connection locations.

Introduction

6.1 This section sets out standards that electric vehicle charge points and cable routes should meet when installed to meet the requirements set out in this Approved Document.

NOTE: This Approved Document does not provide guidance on electrical or fire safety. Electrical and fire safety requirements are likely to apply when carrying out electrical work. Relevant regulations and guidance include the following.

a. Building Regulations Part B (Fire Safety), Approved Document B.

b. Building Regulations Part P (electrical safety – dwellings), Approved Document P.

c. The Electricity at Work Regulations 1989, HSE’s HSR25: The Electricity at Work Regulations 1989: Guidance on Regulations.

Technical requirements for electric vehicle charge points

6.2 Each electric vehicle charge point should meet all the following.

a. Be designed and installed as described in BS EN 61851.

b. Have a minimum nominal rated output of 7kW.

c. Be fitted with a universal socket (also known as an untethered electric vehicle charge point).

Alternatively, in exceptional circumstances, such as for a self-build property, if the vehicle requirements are already known, a tethered electric vehicle charge point may be acceptable.

d. Be fitted with an indicator to show the equipment’s charging status that uses lights, or a visual display.

e. Be a minimum of a Mode 3 specialised system for electric vehicle charging running from a dedicated circuit, or equivalent, as defined in BS EN IEC 61851-1.

f. The requirements of BS 7671.

g. The requirements in the IET’s Code of Practice: Electric Vehicle Charging Equipment Installation.

NOTE: Other legislation may also apply to the installation of electric vehicle charge points. For example, the Alternative Fuels Infrastructure Regulations 2017.

Cable routes and locations for electric vehicle charge points

6.3 For each parking space that requires either

a. an electric vehicle charge point.

b. cable routes for an electric vehicle charge point to be installed in future the location of the electric vehicle charge point or future connection location should be suitable for use by electric vehicles with charging inlets in different places.

NOTE: Often, the best position for an electric vehicle is at one corner of the parking space, as shown in Diagram 6.2.

6.4 Where accessible parking spaces are associated with the building and either

a. future connection locations

b. electric vehicle charge points are being provided to meet the requirements of this Approved Document, at least one accessible parking space should have access to either

c. a future connection location.

d. an electric vehicle charge point.

Diagram 6.1 shows one possible arrangement of electric vehicle charge points for accessible parking spaces.

NOTE: Standards for accessible parking spaces are described in Approved Document M.

6.5 A future connection location may be sited to serve more than one parking space if the cable routes are suitable for electric vehicle charge points to be installed in future that allow all spaces to be used at the same time for recharging – for example, if the cable routes are adequate for an electric vehicle charge point with multiple outlets, where each outlet has the functionality described in paragraph 6.2.

6.6 Where an electric vehicle charge point is sited to serve more than one parking space if the electric vehicle charge point should allow all spaces to be used at the same time for recharging – for example, an electric vehicle charge point with multiple outlets, where each outlet has the functionality described in paragraph 6.2.

Diagram 6.2 shows two possible arrangements of electric vehicle charge points to serve more than one parking space.

6.7 For each parking space that requires cable routes, the following apply.

a. Cable routes should be provided from a metered electricity supply point to the future connection location.

b. All of the following should be provided.

i. Sufficient space for a new electrical connection at a metered supply point such as a consumer unit or feeder pillar.

ii. A dedicated safe and unobstructed route to distribute electricity from the electrical supply point to the future connection location.

iii. A future connection location as specified in paragraphs 6.3 to 6.5.

iv. Labelling as specified in paragraph 6.11

v. Sufficient space to allow an electric vehicle charge point to be installed safely as specified in paragraph 6.12.

NOTE: The following items may also be needed in order to allow an electric vehicle charge point to be installed in future but are not required to meet the standards of this Approved Document.

a. Concrete plinths or footings for future electric vehicle charge points.

b. Vehicle barriers.

c. Electrical cabling.

d. Busbar systems.

e. Upgrades to electrical infrastructure.

6.8 When cable routes are being installed, a suitable strategy should be identified that meets both of the following.

a. The strategy ensures that a future electric vehicle charge point can meet the standards given in both of the following.

i. BS 7671.

ii. The IET’s Code of Practice: Electric Vehicle Charging Equipment Installation.

b. The strategy is specific to both of the following.

i. The location in which a vehicle is likely to be recharged.
