Home EV charger installation: costs and choosing an installer

Hiring an EV charger installer means checking registrations, your electrical supply and paperwork — not fitting it yourself.

EV-01What this job actually involvesInstalling a home EV chargepoint means fitting a wall or post-mounted charging unit, running a dedicated cable back to your consumer unit, and checking your home's earthing is safe for the extra load. The installer also needs to notify the local electricity network and leave you compliance paperwork at the end. Most straightforward jobs are finished in a day, but groundwork for buried cables can add time.

EV-02Legal duties your installer must meetThis is electrical work inside your home, so it's covered by Building Regulations, not something you can wave through informally. Your installer should either self-certify the work through a registered competent person scheme or have it checked by Building Control separately. Newer chargepoints also have to meet smart charging rules set by government.

RULES

KNOW THE RULES

Electrical work in homes is notifiable under Part P of the Building Regulations. Your installer must either be registered with a competent person scheme such as NICEIC or NAPIT and self-certify the work, or the work must be notified to Building Control directly. Since 2022, new chargepoints must also meet the Electric Vehicle Smart Charge Points Regulations, which require smart charging functionality.

EV-03Check whether you need planning permissionMost home chargepoints count as permitted development, so no planning permission is needed. Since 21 October 2026 this also covers flats and chargers away from a driveway. The main exceptions are listed buildings, conservation areas for some positions, and chargers on a wall that faces straight onto a pavement, which have extra conditions. If any of these apply, check before booking anyone.

Planning permission may be required for a listed building, some positions in a conservation area, or a charger on a wall facing straight onto a pavement. HomeGraft has a 'Know the rules' guide on permitted development for EV chargers — check it before you commission the work.

EV-04Who to hire, and in what orderStart with a registered electrician who installs EV chargers regularly — they should visit your property before quoting. If your consumer unit needs upgrading or your supply needs more capacity, that work gets sorted before the charger goes in, not after. You'll rarely need a structural engineer or groundworker, unless you're trenching under a driveway or building a carport around the unit.

EV-05Get your electrical supply assessed firstBefore any quote is final, the electrician should check your earthing arrangement, your consumer unit's capacity, and the distance from the unit to where the charger will sit. Some homes need an earth rod fitted for safety, which adds cost. This assessment should happen on a proper site visit, never over the phone or from photos alone.

EV-06Realistic costs and timescalesFor an average three-bedroom house outside London, expect £800 to £1,200 for a straightforward 7kW chargepoint installation in 2026. More complex jobs — trenching, consumer unit upgrades, an earth rod, or long cable runs — can push costs to £1,500 to £2,500 or more. London and the South East usually cost more than these figures. Most straightforward installs take a day; jobs needing groundwork can take two to three days.

EV-07What a good quote should includeA proper quote names the charger's make, model and kW rating, the cable length and mounting position, and the results of the electrical supply assessment. It should also say whether an earth rod is needed, confirm the network operator will be notified, include Part P certification, and state the warranty length on both the charger and the installation work.

EV-08Questions to ask before you bookAsk if they're registered with NICEIC, NAPIT or a similar scheme, and ask to see proof. Ask whether they'll self-certify under Part P or notify Building Control directly, and whether they'll notify the electricity network operator. Ask about your home's earthing arrangement and whether you'll need an earth rod, and what warranty covers the finished installation.

EV-09Red flags to watch forBe wary of anyone who quotes without visiting your home, can't show registration proof, or doesn't mention earthing or network notification at all. Full payment demanded upfront, before any work starts, is another warning sign. If they can't explain what paperwork you'll get at the end, don't book them.

EV-10What commonly goes wrongThe two biggest problems are earthing issues discovered too late, meaning a costly earth rod gets added on mid-job, and consumer units that turn out unable to take the extra load without an upgrade. Cable runs across driveways can also damage paving if it isn't reinstated properly afterwards. Occasionally homeowners only discover a conservation area restriction once work has already started.

EV-11Paperwork you must get at the endOnce the work is finished, you should receive a compliance certificate and confirmation that the electricity network was notified. Keep both with your house documents — you'll need them if you ever sell the property. Don't make the final payment until you have them in hand.

RULES

KNOW THE RULES

You're entitled to a Part P compliance certificate confirming the work meets Building Regulations. Your installer should also confirm the DNO (electricity network operator) was notified, as this is a separate legal duty on the installer, not optional paperwork.

EV-12If you live in Wales, Scotland or Northern IrelandIn Wales, Building Regulations work in a similar way to England, and the same competent person schemes apply. In Scotland, there's no Part P, and electrical work to a one- or two-storey house usually doesn't need a building warrant, but it must meet Scotland's building standards and can be certified by an electrician in a scheme such as SELECT or NICEIC. In Northern Ireland, Building Regulations are set separately and enforced by local council Building Control. Electricity network notification rules apply UK-wide, as they're about the network, not Building Regulations.

RULES

KNOW THE RULES

Scotland has no Part P; electrical work must meet Scotland's own building standards. Northern Ireland has its own separate Building Regulations and enforcing authority. Check with your local council before commissioning work if you're outside England.
