Choosing the right EV charger installer affects far more than how fast your car charges. It has a direct impact on safety, reliability and how tidy your home looks once the work is finished. Asking the right questions early on helps you separate trusted professionals from box‑tickers in a hurry.
Checking qualifications and accreditations
Before talking about makes of charger or prices, find out who will actually carry out the work. EV charger installation is not a basic electrical job and should only be done by a competent, qualified electrician.
Look for membership of a recognised scheme such as NAPIT or NICEIC, which shows the installer can self‑certify work under Part P of the Building Regulations. For grant‑eligible work, they may also need to be OZEV approved, depending on the scheme in place when you buy.
Professional installers should also hold public liability insurance and be happy to confirm this in writing. If an installer is vague about their accreditations or insurance, treat that as a warning sign and keep looking.
Essential questions to ask before you book
A good installer will welcome detailed questions, as it shows you care about a safe, long‑lasting job. Use the checklist below as a starting point when you first speak to them.
How will you assess my existing supply capacity and consumer unit?
Will the charger be on its own dedicated circuit with the correct RCD/RCBO?
Do you install surge protection devices where required or recommended?
What earthing arrangements will you use for the charger and do I need an earth rod?
How will you route the cable and keep the install neat, especially outdoors?
Will you set up the smart features, app and Wi‑Fi connection with me?
For flats or leaseholds, will you help with permissions from freeholders or managing agents?
What certification and test results will I receive on completion?
Make a note of how clearly they answer and whether they explain things in plain language. If they skip technical checks or say a site survey is unnecessary in most cases, that can lead to problems later.
Load assessment and your consumer unit
One of the first technical checks is whether your existing supply can support an EV charger safely. This is known as a load assessment and should consider your main fuse rating, typical household demand and any high‑load appliances such as electric showers.
The installer should check your consumer unit (fuse board) to see if there is spare capacity, the condition of the board and whether it already has a surge protection device. In some homes, a consumer unit upgrade or an additional small distribution board for the charger is the safest option.
Dedicated circuit, RCD/RCBO choice and surge protection
A properly installed EV charger should run on its own dedicated circuit, protected by the correct cable size and suitable overcurrent protection. This helps avoid nuisance tripping and reduces the risk of overloading existing circuits.
Your installer should explain what type of RCD or RCBO they will use, taking into account the charger manufacturer’s instructions and current regulations. Different chargers can require different protective devices, so “one size fits all” is not acceptable.
Where surge protection is not already fitted, a competent installer will talk you through whether to add it for extra protection of sensitive electronics in both the charger and your home.
Experience with your chosen charger brand
Many homeowners focus on choosing the best charger but forget to ask if the installer regularly works with that brand. Each manufacturer has its own mounting options, smart features and quirks, especially when it comes to Wi‑Fi or load‑balancing settings.
Ask how many of that particular model they have installed and if they are familiar with its app. An installer who frequently fits your chosen brand is more likely to avoid configuration issues and can often suggest the best settings for your usage and tariff.
Cable routing, outdoor ratings and neat finishes
EV installations should be both safe and visually tidy. Poor routing with loosely clipped cables and random trunking not only looks messy but can be vulnerable to damage.
Ask how they plan to route the cable from the consumer unit to the charger and whether they can conceal it where practical. Outdoors, the charger and any connections should have suitable IP ratings for the weather exposure in that location.
It is also worth asking who makes good any drilling through walls and how they will seal holes against drafts and damp. A professional installer will leave the area clean and secure, not with gaps around cables and dust everywhere.
Earthing arrangements and safety considerations
Earthing for EV chargers is a specialist area, particularly for outdoor units. Your installer should be able to explain whether your existing earthing system is suitable and if your charger uses built‑in protection or requires a separate earth electrode.
They should follow current regulations and the charger manufacturer’s guidance to protect against faults and “open PEN” situations on certain supply types. If the installer cannot clearly explain their earthing approach, you should be cautious about proceeding.
Smart features, permissions and common pitfalls
A modern charger is effectively a smart device on your home network. Ask whether the installer will connect it to your Wi‑Fi, update firmware where needed and walk you through the app so you can set charging schedules and monitor usage.
For flats and leasehold properties, permissions can be a major stumbling block. Before booking, clarify whose responsibility it is to obtain consent from freeholders, managing agents or shared parking schemes, and whether drawings or specifications will be provided to support your application.
Common pitfalls include installers who skip a proper survey, leaving you to deal with unexpected extras on the day, or unclear responsibility for reinstatement of finishes. Another frequent issue is messy cable runs that do not match what was discussed, so get the route and charger position agreed in writing.
Documentation and certification you should receive
At the end of the job, you should be given electrical test results, a certificate under the relevant competent person scheme, and any building control notification where applicable. The installer should also register any product warranty and show you how to access the charger’s user manual.
Next steps and arranging a survey
Taking the time to ask these questions up front will help you find an EV installer who prioritises safety, neat workmanship and long‑term reliability over quick wins. A thorough survey, clear explanation of protection measures and a tidy finish are all signs you are in good hands.
