“Special location” is a term from the electrical rulebooks, not a planning category for your garage. In the UK wiring regulations, EV charging installations are covered by dedicated special-installation requirements — which is why a separate IET Code of Practice exists for them. In the United States, the National Electrical Code (NFPA 70) does not class a home charger as a “special location” like a hazardous area; it gives EV charging its own rules and treats it as a continuous load. The label shapes how a fixed installation is designed and certified, not whether you may have a charger.
Key Takeaways
- “Special location” is rulebook language; in the UK it places EV charging among the special installations, in the U.S. the NEC gives charging its own rules instead.
- The practical content is the same on both sides: dedicated circuit, correct protection, certified installation.
- In the U.S., charging is a continuous load — the breaker is 125% of the charger current.
- A plug-in portable charger is an appliance, not a fixed installation.
One Term, Three Rulebooks
The phrase turns up in different books with different meanings, which is where the confusion starts:
| Rulebook | What “special” means there | What applies to an EV charger |
|---|---|---|
| U.S. National Electrical Code (NFPA 70) | Separate chapters cover hazardous (classified) locations and special occupancies | EV charging is not in those classes. It has its own equipment rules and is a continuous load |
| UK wiring regulations | A dedicated part covers special installations and locations, beyond the general rules | EV charging installations sit in that family, with their own requirements; the IET Code of Practice is the installer’s working guide |
| UK building regulations | “Special location” is used for rooms such as those with a bath or shower | A charger is not a bathroom. Its compliance runs through the wiring regulations and the installer’s certification |
What the Dedicated Rules Mean at Home in the U.S.
For a fixed install, the dedicated rules come down to a short list:
- A dedicated circuit. The charger gets its own circuit rather than sharing one with other loads.
- Continuous-load sizing. Charging counts as a continuous load, so the breaker is sized at 125% of the charger current: a 32 A charger needs a 40 A breaker, a 40 A charger a 50 A breaker, and a 48 A charger a 60 A breaker.
- Listed equipment. The charger should carry a recognised safety listing, as our portable EV charger safety guide explains.
- Permit and inspection. New wiring normally goes through your local permit process and is inspected against the code edition your area has adopted. Commercial sites face a longer list, covered in our guide to EV charging station licenses and permits.
What It Means in the UK
Because EV charging sits with the special installations, the compliance route is a competent installer who works to those rules and the IET Code of Practice, then certifies the work and handles any notification that applies. The recognised routes to installers are set out in our guide to becoming an approved EV charger installer in the UK. New-build homes are a separate case: building regulations require charging infrastructure in the build itself, covered in our overview of EV-ready new construction and building codes.
What “Special” Does Not Mean
It does not turn your garage into a hazardous location, or mean the charger needs building approval separate from the electrical work. Nor does it apply to a plug-in portable charger on an existing outlet: that is an appliance, not a fixed installation. If new wiring is added for the outlet, the wiring is the regulated part.
Fixed Installations Are Where the Rules Bite
A hard-wired wall charger is the fixed installation the rules are written for. The EVDANCE EV-ACT5006T 48A Level 2 wall charger is installed hard-wired on a 60 A breaker — the 125% sizing above — or plugged into a NEMA 14-50 outlet. A portable such as the EVDANCE EV-ACS4005T 40A NACS portable charger uses an existing outlet and involves no fixed installation at all.
Frequently Asked Questions
Does my garage become a “special location” once a charger is fitted?
No. The term describes how the installation work is regulated, not a new classification for the room. The charger’s circuit is what gets the dedicated rules.
Does the label mean I need planning permission for a home charger?
Not by itself. The special-installation rules are about electrical safety and certification. For a charger on an existing home the route is normally the certified electrical installation — your installer will flag anything beyond that.
Who decides what applies to my installation?
Your licensed electrician in the U.S., or a competent registered installer in the UK. They work to the local code edition, arrange any permit or notification, and leave you the certificate or inspection record.
