Ratings and review counts are Google's, checked June to July 2026. We list firms that fit EV chargers; we do not check registrations, insurance or prices, so check those before you book. Website links are not paid and carry no tracking.
How the job runs, who your network operator is, and the four checks to make on any installer.
Pick the charger before you ask for quotes, so every installer prices the same job. We compare 26 home chargers A to Z; 25 of them have PEN fault protection built in, which usually means no earth rod.
Most installers start with photos or a visit: where your consumer unit is, the cable route to the parking space, your main fuse and your earthing. Ask for a fixed price in writing that includes VAT and any extra work.
Your installer tells National Grid Electricity Distribution about a new charger. Most single-phase home chargers can be fitted first and notified afterwards; if your supply needs work, such as a bigger main fuse or splitting a shared (looped) supply, the operator has to approve it first.
A standard installation usually takes two to four hours: a new circuit from your consumer unit, the charger on the wall, safety checks and testing. You should get an electrical installation certificate for the new circuit.
Connect the app, set a schedule and switch to an EV tariff. The cheapest overnight rate we compare is 6.5p/kWh, on Intelligent Octopus Go and E.ON Next Drive Smart (November 2026).
Central Cardiff is in the South Wales licence area. Every postcode district we file here is in the same area. Your installer notifies the operator, or asks it first if your supply needs work.
If you rent, or own a flat with private off-street parking, the EV chargepoint grant can cover 75% of the cost of buying and installing a chargepoint, up to £500. It applies across the UK, and only an OZEV-authorised installer can claim it. Wales also has its own support schemes.
We file 39 postcode districts under Cardiff, across 9 council areas. The national networks cover all of them; local firms may not, so give them your postcode first.
Cardiff is also the nearest city we cover for postcodes starting LD and NP.
Installers quote for a named charger, so choose it before you ask. Once it is fitted, an EV tariff is where the savings are.
6.5p/kWh
The cheapest overnight rate of the tariffs we compare: Intelligent Octopus Go, 23:30 to 05:30 and E.ON Next Drive Smart, 00:00 to 06:00 (November 2026, including 0% VAT). Your day rate and standing charge depend on your region, South Wales.

DNO approval explainedIf you rent, or own a flat with private off-street parking, the EV chargepoint grant can cover 75% of the cost of buying and installing a chargepoint, up to £500. It applies across the UK; your installer must be OZEV-authorised to claim it. Checked October 2026.
The EV chargepoint grant explainedA standard installation usually takes two to four hours. A long cable run, groundworks or consumer unit work can take most of a day.
How a home charger is installedUsually not with a modern charger: 25 of the 26 chargers we compare have PEN fault protection built in, which usually removes the need for one. Your installer makes the final call.
Earth rods explained39 postcode districts in 9 council areas, from CF3 to CF99. National networks cover all of them; local firms may not, so give them your postcode first.

Stars and review counts come from each firm's Google listing, checked June to July 2026. We never rate installers ourselves.
Each city lists its local firms first, then the national networks, and each group runs by number of Google reviews. If a firm ever pays to be featured, it sits in its own labelled frame and never changes the list. How we make money
