Installing an EV Charger on a Terraced House in Cardiff
Terraced houses in areas like Roath, Canton and Cathays are common across Cardiff — and they can make EV charger installation trickier than a suburban semi with a drive. Here is what to consider before fitting a home charge point, and how the job is done safely.
Can you install a charger on a terraced house?
Yes. A wall-mounted 7kW charger can be fitted to the front or rear wall of a terrace, with a dedicated cable run from the consumer unit. The main considerations are where the car parks, how the cable reaches it safely, and whether your fuse board has the capacity for a new dedicated circuit.
Driveway versus on-street charging
If you have even a small front space to park on, a charger beside the bay is straightforward. With no off-street parking, the cable must not be trailed across the pavement where it becomes a trip hazard. Some homeowners use approved cable management, but on-street charging usually needs a council-approved solution rather than a private cable across public land.
Checking your fuse board capacity
An EV charger needs its own dedicated, protected circuit. In older terraces the consumer unit may lack spare ways or surge protection, so an upgrade to an 18th Edition metal board — or a separate compact garage unit — may be required first. We also check your main supply fuse and can fit dynamic load balancing so the charger does not overload the incoming supply.
Smart tariffs and solar
Smart chargers such as Ohme, Pod Point and myenergi Zappi connect to your phone and can charge automatically during cheap off-peak hours. If you have solar panels, a Zappi can divert surplus generation straight into your car, lowering running costs further.
The installation process
- Site survey and electrical capacity assessment.
- Dedicated heavy-duty cable from the consumer unit to the charger location.
- Neat mounting of the wallbox with tidy, safe cable management.
- Commissioning, smart app setup and full electrical certification.
Frequently asked questions
Do I need council permission for a home EV charger?
Most wall-mounted home chargers fall within permitted development, but any on-street or pavement work has separate rules and requires approval. We recommend checking with Cardiff Council before planning an on-street solution.
Can I charge an EV without a driveway?
Yes, but it is harder. Options include a charger sited to reach a parked car with a tidy, safe cable run, or qualifying on-street charge point schemes. We assess each property and advise on what is safe and practical.
