Part S
Plain English. Practical detail. UK context.
Part S is England's Building Regulations provision on infrastructure for charging electric vehicles. Approved Document S describes relevant charging-point and cable-route requirements for defined building work. It does not mean every existing driveway must immediately receive a charger or that every parking space has identical obligations.
Safety: use a registered electrician, for example one registered with a competent person scheme such as NICEIC or NAPIT, for electrical installation work. Do not remove covers or open electrical equipment yourself.

Start with the building-work category
New residential buildings, relevant changes of use, major renovations and non-residential work have distinct provisions and conditions in the guidance. Associated parking and the scope of the work matter. Homeowners or developers should explain the project and parking arrangement before ordering equipment. Tradespeople need the applicable requirement and design responsibility identified, not a blanket statement that Part S requires one charger everywhere. Exceptions and cost-related provisions must be checked in the actual guidance. An ordinary standalone retrofit installation and a development subject to Part S are not automatically the same compliance exercise.
A charger and a future cable route differ
Some provisions concern installed charge points and others concern cable routes for later installation. A prepared route should not be sold as a live functioning charger. Location, access, protection and the intended parking arrangement need coordination. Trainees should understand which elements are specified and record concealed routes before closure. Do not install an arbitrary empty duct and assume it satisfies every future requirement. Provider, supply and site constraints may need further design decisions. The actual guidance and product information should determine the arrangement, not a convenient leftover cable or spare enclosure.
Electrical competence remains essential
Part S does not replace electrical safety requirements, appropriate design or BS 7671 for the applicable installation. Supply capacity, protective arrangements, earthing, isolation and testing need competent assessment. This article gives no wiring recipe or universal cable size. Trainees should work within their supervised role and recognise when a specialist or network decision is needed. England's other Approved Documents provide relevant building context. HSE electrical and construction guidance addresses safe execution, excavation and services. Product marketing or smart features alone do not establish a suitable installed system.
What the homeowner should receive
Agree the equipment, location, cable routes, design, supply interfaces, testing, notification and making good. Explain normal controls, charging limitations, maintenance and any separate service arrangements. Keep relevant electrical and product records with the building evidence. Prices and outcomes vary from job to job, so compare written, itemised quotations rather than relying on a typical figure. The applicable national framework must be checked outside England. Tradespeople should record authorised changes, while homeowners should understand the distinction between infrastructure compliance, electrical safety and retail energy or charging services. A working app is not proof that every concealed or supply-related design question has been resolved.
Frequently asked questions
Does Part S require a charger in every existing home now?
No. Its application depends on defined building work and the actual provisions.
Is a future cable route the same as an installed charger?
No. Clarify what is required, designed and delivered for the project.
