EV charger in a new build: what Part S means for you.
What is Part S of the Building Regulations?
Part S is the section of the Building Regulations in England that sets minimum requirements for electric vehicle infrastructure in new and significantly renovated buildings. It came into force on 15 June 2022 and applies to:
- New residential buildings with associated parking
- Existing residential buildings undergoing major renovation, where there are more than 10 parking spaces
- New non-residential buildings with more than 10 parking spaces (offices, retail, etc.)
For new homes — the most common situation buyers encounter — Part S requires at least one functional EV charge point per dwelling where parking is provided. That charge point must deliver a minimum of 7kW and must comply with the Electric Vehicles (Smart Charge Points) Regulations 2021.
What developers are legally required to install
For a new residential building with parking, the developer must install at least one EV charge point per parking space associated with a dwelling. The charge point must:
- Be capable of delivering a minimum 7kW charge rate
- Have a socket outlet (Type 2 is standard in the UK) or cable management system with a socket outlet
- Comply with the Smart Charge Points Regulations 2021 — meaning it must be a smart charger with scheduling capability
- Be installed by a qualified electrician and covered by an Electrical Installation Certificate
The regulation also covers the electrical infrastructure behind the charger: the developer must ensure the dwelling's consumer unit has sufficient capacity, and that cabling is appropriately sized for the load.
What new build buyers actually get in practice
The gap between what Part S requires and what buyers receive varies significantly by developer. Here is what different levels of compliance look like in practice:
| What developer installs | Part S compliant? | What it means for you |
|---|---|---|
| Full 7kW smart wallbox, working and commissioned | Yes — fully compliant | Plug in and go. You may still want to upgrade to a preferred brand. |
| 7kW socket outlet (untethered), no specific brand charger | Yes — compliant | Works, but no dedicated app or smart scheduling until paired with a cable. |
| Cable run + consumer unit capacity, no socket | Disputed — developer should install a socket | You need an installer to add the wallbox. Fast job (1–2 hrs) if cabling is in place. |
| Nothing — developer claims shared parking exemption | Only if truly communal — check the small print | If you have allocated parking, challenge the developer or contact your local authority. |
The most common complaint from new build buyers is receiving a basic, low-cost charger that lacks app control, smart tariff integration, or solar divert — all of which require an upgraded model. This is legal under Part S, which sets a floor, not a ceiling.
Upgrading your builder's charger installation
If your new build has a compliant but basic charger and you want to replace it with a Zappi, Ohme, or Hypervolt, the process is straightforward:
- 01Check what cabling is already in placeA new build that complies with Part S already has a 32A dedicated circuit from the consumer unit to the parking position. This is what a 7kW wallbox requires. Any OZEV-authorised installer can confirm this during a free survey.
- 02Choose your replacement chargerThe most popular upgrades from builder installs are the Zappi (for solar owners), Ohme Home Pro (for Octopus Energy users), and Hypervolt Home 3 (for solar-compatible mid-range). All work on the existing 32A circuit.
- 03Book an OZEV-authorised installerSwapping one wallbox for another on an existing circuit typically takes 1–2 hours. The installer removes the old unit, fits the new one, commissions it, and updates the Electrical Installation Certificate.

Can you claim the OZEV grant on a new build?
The OZEV EV Chargepoint Grant (up to £500 off installation costs) is targeted at renters and leasehold flat owners — not homeowners with their own parking space. If you are buying a new build house with its own driveway or parking bay, you are unlikely to qualify for the grant.
| New build buyer type | OZEV grant available? |
|---|---|
| New build house owner with private parking | No — homeowners with dedicated parking do not qualify |
| New build flat owner (leasehold) with allocated parking | Potentially yes — leasehold flat owners can qualify if other criteria are met |
| New build flat renter with allocated parking | Potentially yes — renters can qualify if other criteria are met |
If you are buying or renting a new build flat and think you may qualify, see our detailed guide on the EV charger grant for flats.
Part S in Scotland and Wales
Wales follows England's Part S requirements. New builds in Wales with parking are subject to the same 7kW minimum and smart charger requirements as England.
Scotland has its own building regulations. The Scottish Government consulted on EV charger requirements for new builds, and similar provisions are being phased in, but the implementation timeline and exact requirements differ from England. Check with your developer or local authority for the specific rules applicable to your site.
Northern Ireland has its own building regulations and has not enacted equivalent Part S requirements at the time of writing (November 2026). New builds in Northern Ireland are not subject to the same mandatory EV provision.
