About ev charger installation in Merton

A home EV charger (wallbox) is installed on a dedicated 32A circuit from your consumer unit, giving you a full overnight charge at a fraction of the cost of public charging. The installation covers everything from the electrical survey through to commissioning and Part P certification. Most standard installations are completed in half a day.

EV charger installation is notifiable electrical work under Part P of the Building Regulations. It must be carried out by a qualified electrician registered with a competent person scheme (NICEIC, NAPIT, or ELECSA). A dedicated circuit is required — you cannot safely run a 7kW charger from an existing socket circuit. DIY installation is illegal and invalidates your charger warranty.

EV Charger Installation FAQs

Can I install an EV charger myself?

No. EV charger installation is notifiable electrical work under Part P of the Building Regulations. It must be carried out by a qualified electrician registered with a competent person scheme. DIY installation is illegal, voids the charger warranty, and can invalidate your home insurance.

Do I need to upgrade my consumer unit?

Possibly. A 32A EV charger circuit needs a spare way in your consumer unit and adequate capacity. If your board is an old rewirable fuse box, a small board with no spare ways, or does not have RCD protection, it will need upgrading. Your electrician assesses this during the site survey.

How long does a full charge take on a 7kW home charger?

A 7kW charger delivers approximately 30 miles of range per hour. A typical 60kWh EV (like a Tesla Model 3 Standard Range) takes about 8-9 hours from empty to full — comfortably overnight. Most daily top-ups take 3-5 hours.

Am I eligible for the OZEV grant?

The OZEV EV Chargepoint Grant provides up to £350 towards installation costs. As of 2024, it is available to renters and residents of flats only — homeowners in houses are no longer eligible. The charger must be smart-enabled and installed by an OZEV-approved installer.

What happens if my electricity supply is not strong enough?

Your DNO can upgrade your main fuse to 80A or 100A, usually for free. This gives more headroom for EV charging alongside your household demand. The upgrade typically takes 2-4 weeks to arrange. Alternatively, a charger with load management can dynamically reduce its power when other household loads are high.

What is the difference between a tethered and untethered charger?

A tethered charger has a cable permanently attached — grab and plug in. An untethered charger has a socket where you connect your own cable. Tethered is more convenient for a single EV; untethered is more flexible if you have multiple vehicles with different connectors.
