Choose a UK EV charger installer for demonstrated electrical competence, a property-specific survey, clear paperwork and accountable aftercare, not for the flashiest charger brand on the van. Ask how they handle earthing, RCD strategy, open PEN protection, smart charge-point rules and DNO notification or application. Compare like-for-like written scopes, then favour the contractor who explains risks honestly over the one who only undercuts on price.
Start with competence, not catalogue photos
Home charge-point work is electrical installation work with network and safety implications. Check that the business can show relevant qualifications, membership of a competent person scheme where they rely on that route for Building Regulations notification, public liability insurance and a clear complaints path. Manufacturer installer lists can be useful filters, but they are not a substitute for checking the people who will attend your home.
If a grant or workplace scheme is involved, confirm the installer meets that scheme's current accreditation rules before you pay a deposit. Scheme logos on a website can be out of date.
- Ask who will survey and who will install.
- Request proof of insurance and scheme membership you can verify.
- Check recent domestic install experience for similar property types.
- Avoid cash-only offers with no written contract.
Judge them on the survey conversation
A strong installer talks about your parking geometry, consumer unit, earthing arrangement and cable route before pushing a particular wallbox. Weak sales calls jump straight to a discounted model. The survey should produce photos, assumptions and a scope you can send to a second bidder for comparison.
Listen for specific safety language: dedicated circuit, protective device selection, isolation, outdoor IP rating and how they will commission smart functions. Vague reassurance that everything will be fine is not evidence.
Understand network and compliance handling
Installers should know when Connect and Notify is available and when prior DNO approval is required under Energy Networks Association processes. They should also understand that private charge points placed on the GB market must meet smart charge-point regulations, including smart functionality and default scheduling behaviour set out in the rules.
Building Regulations duties depend on the work and the notification route used. Ask who submits what, and what certificates you will receive. For new builds and major parking works, Approved Document S may also be relevant, though many retrofit driveway jobs are driven more by electrical safety standards than by Part S charge-point counts.
Compare commercial terms and aftercare
Look beyond the hardware warranty. Ask who diagnoses a failed charger in year two, whether labour is included, how software support works if the app changes, and what happens if Wi-Fi is unreliable. Prefer itemised labour, materials, making-good and provisional sums over a single round number.
Deposits should be proportionate. Stage payments tied to survey, materials order and completion are easier to manage than large upfront sums to unfamiliar traders. Keep everything in writing.
Use local knowledge without inventing scarcity
Local experience with terrace parking, basement flats or particular DNO processes can speed a job, but every property still needs its own survey. Do not assume a neighbour's install proves yours is identical.
Shortlist two or three surveyed quotes. Consistency of technical story across bidders is a good sign. A single ultra-cheap outlier that skips earthing or network steps deserves scrutiny, not automatic acceptance.
Frequently asked questions
Is the cheapest EV installer usually fine?
Not if the scope is thinner. Missing board upgrades, incomplete making-good or skipped network steps can erase the saving. Compare inclusions first.
Do I need an OZEV-approved installer?
You need an installer who meets the rules of any grant or scheme you are claiming, and who can install safely and compliantly. Approval labels matter when a scheme requires them; they are not the only quality test for a private-pay job.
Should I buy the charger myself online?
You can, but the installer must still accept the product as suitable and compliant. Many prefer to supply and install so warranty and smart-regulation responsibilities stay aligned.
What documents should I keep?
Quotation, signed scope, electrical certification, model and serial numbers, warranty registration, DNO notification or approval evidence, and handover notes for the app and schedule.
