Garage mounting suits many homes when the car parks inside or immediately outside with a short, tidy cable route. Driveway or exterior wall mounting suits open parking, larger vehicles and households that rarely use the garage for cars. The better choice is the one that keeps daily plugging simple, protects the cable, and stays electrically compliant. A survey should test real parking positions rather than assume the nearest brickwork is best.
Start with where the car actually parks
Many UK garages store tools, bikes and freezers while the EV lives on the drive. A beautifully wired garage charger is poor value if you never open the door to charge. Mark the usual parked position, charge-port location on your vehicle, and any second-car conflict before choosing a wall.
Tethered cable length and untethered socket height both matter. A garage unit may need the door open and the cable passed through, which becomes annoying in rain or overnight security routines.
- Measure from proposed charger to the vehicle inlet in the normal parked stance.
- Check door swings, gate arcs and wheelie-bin routes.
- Note whether guests will also need temporary access to the unit.
Weather, IP ratings and condensation
Exterior chargers must be suitable for outdoor conditions and installed to manufacturer instructions. Driveway walls and posts are exposed to rain, UV and occasional vehicle wash spray. Garage interiors are sheltered but can be damp, dusty or poorly ventilated.
Condensation and corrosion risks are design issues, not reasons to avoid outdoor chargers that are correctly specified. Likewise, a garage is not automatically safer if the mounting wall is weak, cluttered or used for flammable storage beside the unit.
Cable routing and making good
Garage installs often enjoy shorter internal routes to the consumer unit, which can reduce labour. Driveway installs may need SWA across gardens, under paths or along walls, with higher reinstatement cost.
Ask the surveyor to price both options when the decision is close. A slightly longer outdoor run to the true parking bay usually beats a short run to the wrong place.
Security, lighting and household use
Driveway units are more visible to passers-by. Consider lighting, cable tidy habits, and whether a tethered lead will be left out. Garage units reduce casual interference but can be awkward if the garage is shared or rented separately from the house.
Smart scheduling still works in either location. The siting decision should serve daily behaviour first, then aesthetics and cable cost.
- Avoid mounting where a cable creates a trip across a shared path.
- Keep isolation accessible without climbing over stored items.
- Plan future second-vehicle access if relevant.
Frequently asked questions
Is a garage charger always cheaper?
Often the electrical route is shorter, but not always. If the car does not park in the garage, driveway mounting can be better value despite a longer cable run.
Can I mount a charger on a freestanding post on the drive?
Yes, when designed correctly with suitable foundations, cable protection and manufacturer approval. Posts help when wall positions are poor.
Do I need ventilation because batteries charge in a garage?
Follow charger and vehicle manufacturer guidance. Modern EV charging is not the same as charging lead-acid forklift banks, but clutter, heat and storage of fuels beside equipment still need common-sense risk control.
What if my garage is detached?
A detached garage may need an outdoor submain or long SWA route from the house intake. Capacity, earthing and trench costs become central survey items.
