Installing a home EV charger is not just about convenience. It is about safety, compliance, and making sure your money is well spent. This guide walks you through exactly how to find an approved EV charger installer UK homeowners can trust — what “certified” actually means, where to look, how to vet installers properly, and the red flags to avoid.
Why using an approved installer matters
A home EV charger is a high-powered electrical installation. If it is installed incorrectly, the risks range from nuisance tripping to serious electrical faults and fire hazards. Using an approved installer ensures the work meets UK electrical regulations, is safe for long-term use, and protects your home.
Certification also affects your wallet. Any government grant support — including the OZEV grant for eligible properties — requires the work to be carried out by an OZEV-approved installer. Use someone unapproved and you will not be able to claim.
Most charger manufacturers also require professional installation by an approved installer to keep the warranty valid. A cheap quote from an unapproved electrician can cost far more in lost grants and voided warranties.
What “certified” means for EV charger installers
In the UK, “certified” refers to specific accreditations that demonstrate competence, compliance, and accountability — not just a marketing badge.
An OZEV-approved installer is required for any government grant. These installers are vetted by the Office for Zero Emission Vehicles and must meet technical, insurance, and quality standards. If grant eligibility matters to you, this is non-negotiable.
The UK's main electrical contractor bodies. Membership shows an electrician is regularly assessed, properly insured, and competent to carry out electrical work. A strong sign of professionalism, though not EV-specific on its own.
A government-backed quality scheme covering workmanship, customer service, and consumer protection. Installers registered with TrustMark have agreed to a code of conduct and offer additional reassurance.
Our recommendation
Always start with OZEV approval as your baseline. Other accreditations add confidence, but OZEV-approved is the minimum you should accept.
Where to find approved EV charger installers
1. CertifiedInstaller.co.uk
The simplest option. Search by postcode or town and every installer listed is already OZEV-approved. This removes the need to manually cross-check credentials — it is designed specifically for homeowners who want a trustworthy starting point rather than a gamble.
2. OZEV installer register on gov.uk
The government maintains its own public register of approved installers, searchable by company name or location. This is the definitive source for confirming OZEV status, though it is not always the easiest to browse. View the register on gov.uk.
3. Charger manufacturer installer networks
Many charger brands run their own approved installer networks — including Zappi (myenergi), Pod Point, and Hypervolt. These installers are trained on specific products, which can be useful if you have already chosen a charger. The downside is that choice may be limited by brand and location.
4. Word of mouth from other EV owners
Friends, neighbours, or local EV owner groups can be valuable sources of honest feedback. Always double-check that any recommended installer is still OZEV-approved before booking.
What to avoid
Avoid relying on random Google searches without verifying credentials. General handymen or electricians without OZEV approval may be cheaper upfront but can cost more in lost grants, invalid warranties, and future repairs.
How to vet an EV charger installer properly
Once you have a shortlist, use this checklist to compare installers fairly. For cost expectations, see our guide to EV charger installation costs.
Check OZEV approval
Ask for their company name and confirm it on the official register. Do not rely on logos alone.
Look at reviews
Check Google or Trustpilot and focus on recent feedback — ideally from the last 6–12 months. Patterns matter more than one-off complaints.
Get a written, itemised quote
A professional installer will clearly break down labour, charger cost, cabling, and any extras. This also makes quotes easier to compare.
Consider location
Local installers are often cheaper and more flexible. Long travel distances can increase costs and make follow-up visits inconvenient.
Clarify charger supply
Some installers supply the charger; others expect you to buy it separately. Know exactly what is included before accepting a quote.
Ask about the labour warranty
Most reputable installers offer a 12-month labour warranty, separate from the charger manufacturer's warranty.
Questions to ask before booking
Before you commit, ask these practical questions. Clear, confident answers are usually a sign of a professional operation.
- Are you currently OZEV-approved, and can I verify this on the register?
- Does your quote include everything, or could there be additional costs after inspection?
- How long will the installation take, and will there be any disruption to power?
- Do you handle the OZEV grant paperwork if applicable?
- What warranty do you offer on your installation work?
- If there is a fault later, how quickly can you return?
Red flags to watch out for
Be cautious if an installer shows any of the following signs. If something feels rushed or unclear, walk away.
- !No OZEV approval, or refusal to share registration details
- !No written or itemised quote
- !Requests for full payment upfront
- !No reviews, or only very old reviews
- !High-pressure tactics pushing you to book immediately

Do I need an OZEV-approved installer?
If you want to claim any OZEV grant, yes — it is a requirement. Even without a grant, OZEV approval is a strong indicator of competence and compliance with UK electrical regulations.
How many quotes should I get?
Two to three quotes is usually enough to understand fair pricing and spot outliers. More than three rarely adds much, and it can slow down the process unnecessarily.
How do I check if an installer is legitimately approved?
Use the official OZEV register on gov.uk and cross-check any accreditation numbers they provide. You can also start with verified listings on CertifiedInstaller.co.uk, where every installer has already been confirmed as OZEV-approved.
