Ireland's Building Regulations have required EV charging infrastructure in new homes since 1 November 2022. The rule lives in the Building Regulations (Part L Amendment) Regulations 2022 — Statutory Instrument 535 of 2022 — and it applies to any new dwelling or multi-unit residential building whose works started on or after that date. The headline takeaway: new Irish homes need ducting for an EV charger; existing homes use the SEAI Home Charger Grant route instead.
Quick summary: Part L 2022 requires EV recharging infrastructure (ducting/conduits) at car parking spaces inside the curtilage of new dwellings. Multi-unit buildings need ducting at each parking space. Existing homes are not affected and use the €300 SEAI Home Charger Grant route.
What does Part L say about EV charging?
The 2022 amendment added EV charging infrastructure to the energy-performance requirements of the Building Regulations. The Department of Housing, Local Government and Heritage announced the change on 11 November 2022, and it applies to works that commence on or after 1 November 2022. The Statutory Instrument is S.I. No. 535/2022 and is the primary source for the rule.
The requirements depend on the type of building:
- New single dwellings (not part of a multi-unit building): appropriate electric vehicle recharging infrastructure must be installed to enable the subsequent installation of a recharging point, where a parking space is located within the curtilage (boundary) of the dwelling.
- New multi-unit residential buildings: ducting infrastructure — conduits for electrical cables — must be installed at each car parking space located inside or within the curtilage of the building.
- Major renovation of existing multi-unit buildings: the same ducting requirement applies, but only where the renovation specifically includes the car park or its electrical infrastructure.
The reason the regulations talk about "infrastructure" rather than a fully fitted charge point is deliberate: Part L's job is to make sure the conduit, supply capacity and wiring route are designed in from the start, so the eventual charger can be added without ripping up the driveway or chasing fresh cable runs through a finished house.
Does Part L apply to existing homes?
No — and this is the most common misunderstanding. Part L 2022 applies to new construction and to major renovations that include the car park or the building's electrical infrastructure. If you live in a typical Irish home built before November 2022 and you are not doing a major renovation, Part L does not require you to install anything.
For existing homes, the route to a home EV charger is the SEAI Electric Vehicle Home Charger Grant, administered by the Sustainable Energy Authority of Ireland. SEAI confirms the grant is €300 flat towards the purchase and installation of an approved home EV charger, paid as a refund after installation. The criteria SEAI publishes for the grant include:
- You are a homeowner with off-street parking on the property's MPRN.
- You have not previously received the grant at this property (one grant per MPRN).
- The charger is on SEAI's Smart Charger Register.
- The installer is a Safe Electric registered electrician.
- You do not need to already own an EV to apply.
So the practical answer for a homeowner reading this article is: Part L is the rule for the builder of a new house. The SEAI grant is the route for a homeowner of an existing house. They do not overlap.
What about new builds — is ducting enough?
Part L requires the infrastructure, not a working charger. In practice that means a builder is meeting the regulation if they install a conduit running from the consumer unit area to the parking space inside the curtilage, sized to allow a 32 A single-phase circuit to a future EV charger. The charger itself is usually fitted later by the homeowner, often funded through the SEAI Home Charger Grant once the house is occupied.
That two-step approach — ducting now, charger and grant later — is the most cost-efficient path for most new builds, and it is why Part L is written the way it is. It also means new-build buyers should ask their builder a specific question before contracts are signed: where is the EV charger duct terminated, and what circuit is it sized for? The answer should be a clear point on the consumer unit side and a clear point near the parking space, with a 32 A / 7.4 kW provision being the typical home target.
How does Part L fit with the SEAI €300 Home Charger Grant?
The two policies are complementary, not competing. Part L makes sure new homes are ready for a charger; the SEAI grant funds the actual charger and installation, whether the home is new or existing.
For Volt Éire customers, that means the same fixed-price Standard Installation pathway applies whether you are in a brand-new build with Part L ducting waiting at the parking space, or in a 1970s semi-d that needs a cable run designed from the consumer unit. In both cases the journey is photo assessment, Safe Electric installation, certification and SEAI paperwork — see Standard Installation for the six things we check from your photos before confirming the €1,299 fixed price.
UK Part S vs Irish Part L: a quick comparison
If you have read commentary about UK Approved Document S (the 2022 EV charging building regulation for England), you may have noticed that it is materially stricter than Ireland's Part L. The headline differences:
| Aspect | Ireland — Part L 2022 | UK England — Approved Document S |
|---|---|---|
| In force from | 1 November 2022 | 15 June 2022 |
| New single dwelling with parking | Ducting/conduit infrastructure required | A working EV charge point required at each parking space |
| Smart/connectivity requirement | Not specified in Part L (SEAI grant separately requires a smart charger from its register) | WiFi communication required on chargers installed after 30 June 2022 |
| Cost cap on connection | None specified | Approx. £3,600 average cap per charge point connection |
| Covered car parks | No specific exemption | Charge points not required in covered car parks (fire risk); cable routes required instead |
The simplest way to read the difference is that the UK has front-loaded the cost of EV readiness onto the developer (a charger goes in with the house), while Ireland has front-loaded only the ducting and left the charger itself to the SEAI grant programme. Both approaches reach the same end-state — every new home with off-street parking ends up with a charger — but via different routes.
What should an Irish homeowner do today?
Three quick decision branches, depending on where you are:
- Buying or moving into a new build: ask the builder to confirm Part L compliance. Specifically: where the EV duct enters the consumer unit area, where it terminates at the parking space, and what circuit it is sized for. If the answer is anything other than "ready for a 7.4 kW charger", get it written down before signing.
- Living in an existing home: Part L does not apply to you. Use the €300 SEAI Home Charger Grant route. Volt Éire handles the SEAI application paperwork as part of our standard installation service.
- Doing a major renovation: if the works include rebuilding the car park or the building's electrical infrastructure, Part L applies and your builder should design ducting in. Talk to your architect or building professional before final drawings.
The Volt Éire route — same outcome, regardless of Part L
Whether your home was built last year with Part L ducting or twenty years ago without it, the Volt Éire installation service ends the same way: a Beny 7.4 kW smart charger installed by a Safe Electric registered electrician, the SEAI €300 grant claimed for you, certification on the day of install, and a fixed €1,299 all-in price (€999 net after the grant). New-build Part L ducting can shorten the cable route on install day; the price stays the same.
