A home charger turns an electric car from a planning exercise into something you just plug in at night. A typical 7kW wall charger adds about 25 to 30 miles of range per hour, charges a family EV overnight on a cheap tariff, and costs a fraction of public rapid charging per mile.
Installing one properly is more than screwing a box to the wall. The charger needs its own dedicated circuit from the consumer unit, protection against a specific hazard called a PEN conductor fault (most modern chargers handle this internally, and we check yours does), a load assessment to make sure your supply can carry the extra demand, and notification to your electricity network operator (the DNO).
We install EV chargers across Greater London: driveways, side walls, garages and, where the freeholder agrees, allocated parking at flats. We fit chargers you have already bought or supply one, and we will tell you honestly if your preferred spot will cost more than moving it a few metres.
What's included
Supply and load check first
We check your main fuse size, earthing arrangement and existing maximum demand before quoting. A 7kW charger draws 32A continuously, and some older London supplies with 60A fuses need load management or a fuse upgrade from the DNO.
A dedicated, properly protected circuit
The charger gets its own circuit in appropriately sized cable (typically 6mm or 10mm twin and earth, or SWA for external runs), protected by its own RCBO. No spurring off the shower circuit, no shared ways.
PEN fault and earthing done right
Chargers on typical London PME supplies need protection against a broken neutral making the car live. We confirm the charger has compliant built-in open-PEN protection, or design the earthing to suit.
Charger supplied or customer-provided
We fit the mainstream units (Ohme, Zappi, Hypervolt, Easee and similar) and recommend based on your car, tariff and solar plans, not on commission. If you already have a unit, we install it.
DNO notification and certification
We notify your network operator of the installation as required, commission the charger and app with you, and issue an Electrical Installation Certificate with full test results.
How the job runs
- 1
Photos and a quick assessment
Send photos of your consumer unit, the main fuse and meter, and where you want the charger. That is usually enough for an accurate quote; for longer cable runs or flats we survey in person.
- 2
Fixed quote and charger choice
You get a written price covering the charger (if we supply it), the circuit, any earthing work and the DNO paperwork. We agree the cable route with you before anything is drilled.
- 3
Installation
Most installations take half a day to a day: new circuit from the board, cable run clipped, in trunking or buried to the charger position, unit mounted and terminated. Power is off briefly while we connect at the board.
- 4
Testing and commissioning
The circuit is tested to BS 7671, the charger's protective functions are verified, and we commission the unit, connect it to your wifi and set up the app with you.
- 5
Paperwork and handover
You receive the Electrical Installation Certificate, the DNO notification is submitted, and we register the manufacturer's warranty where applicable.
What it costs
A standard installation starts from £900 including a quality 7kW smart charger, with most London jobs finishing between £900 and £1,400. The main variables are the charger you choose (a Zappi with solar integration costs more than a basic tethered unit), the cable run (a charger on the wall beside the consumer unit is cheap; forty metres through a Victorian terrace to a rear parking space is not) and whether groundwork or SWA cable is needed outside.
If your main fuse needs upgrading, that work is done by your network operator and is often free, but it adds lead time. Flats and rentals may qualify for the OZEV chargepoint grant, which we can process where eligible. Either way, the full price is confirmed in writing before installation day.
