For an existing home, fitting a wall charger does not normally mean applying for building regulations approval as a separate step. The installation is regulated electrical work: it must meet the UK wiring regulations, and a competent installer certifies the work and handles any notification that applies. Building regulations bite directly in a different place — new homes, where they require charging infrastructure to be built in from the start.
Key Takeaways
- Existing homes: no separate building regulations application for a wall charger — compliance runs through certified electrical work.
- New homes: building regulations require charging infrastructure in the build, handled by the developer.
- The charger itself is covered by the Smart Charge Points Regulations 2021; the workmanship by the wiring regulations and IET Code of Practice.
- Keep the installer’s certificate, and treat pavement crossing as a separate council matter.
Two Rulebooks That Get Confused
“Building regulations” and “electrical rules” are often used as if they were the same thing. They are not. Building regulations govern the building itself, and their EV requirements target new construction. The safety of an installation in an existing home is governed by the national wiring regulations, with the IET’s Code of Practice as the working reference installers follow. The device itself is also regulated: the Smart Charge Points Regulations 2021 set the smart functionality and security requirements for private chargers sold in Great Britain.
| Situation | What applies | Who deals with it |
|---|---|---|
| New-build home | Building regulations require charge point infrastructure in the build (in England, Part S) | The developer, as part of the build |
| Wall charger on an existing home | Wiring regulations and the IET Code of Practice; installer certifies the work and handles any notification that applies | Your installer — you keep the certificate |
| The charger you buy | Smart Charge Points Regulations 2021 for private chargers sold in Great Britain | The manufacturer and seller |
| Charging across a pavement | A separate local-authority route, covered by government guidance | You, with the council — see the linked guide below |
New Homes Are the Developer’s Problem, Not Yours
If you are buying a new-build, the charging question should already be answered by the build itself: the regulations behind it, and what “EV ready” does and does not guarantee, are covered in EV-ready new construction and 2026 building codes. Your job is to check what was actually installed — a charge point, or only the cabling for one.
What Compliance Looks Like on an Existing Home
- Use a competent installer who works to the wiring regulations and the IET Code of Practice; the route to recognised installers is explained in how to become an approved EV charger installer in the UK.
- The installer certifies the completed work. Keep the certificate with your installation paperwork — it evidences a job done to standard.
- Rules and notification duties differ across the UK’s nations, so let the installer confirm what applies at your address.
- Buy a charger that meets the GB smart charging rules and carries the right conformity marking — the distinction is set out in UKCA vs CE for chargers sold in Great Britain.
- Planning permission and notifying your network operator are separate questions from building regulations; a wall-mounted unit such as the EVDANCE EV-ACT3204PE 22 kW wallbox (Type 2, RFID and app, CE) is the kind of installation your installer handles end to end. A plug-in portable such as the EVDANCE EV-ACS3210E 32A Type 2 portable charger involves no fixed installation at all.
The Pavement Exception
If your charging cable would cross a public pavement, a different set of permissions applies, covered by government guidance on cross-pavement solutions. Our guide to running a charging cable across the pavement walks through the position. It is a highways and council matter, not a building regulations one.
Frequently Asked Questions
Do I need building control approval before my installer starts?
For a charger on an existing home, homeowners do not normally make a separate building regulations application — the compliance route is the certified electrical installation itself. Building work beyond the charger, such as a new garage, has its own rules, which your builder or installer will flag.
Does a portable charger need any of this?
No installation means no installation rules: a portable charger plugs into an existing suitable socket. The socket circuit still has to be sound, and an electrician can check it — but there is no certified installation because nothing is installed.
Who checks that my installation complies?
Your installer certifies their own work under the competent-person arrangements for electrical work, and issues the certificate. That is why choosing a properly registered installer matters more than any form you could file yourself.
