How many sockets you have, roughly where the site is, and who installed it. Companies that have since stopped trading are common, and not a barrier.
EV charger maintenance contractsfor apartment blocks,workplaces and fleets.
We keep EV chargers working on sites that somebody else has to answer for. Planned visits, monitoring in between, and a response time you can put in front of residents or a board.
Brands we maintain 
We maintain chargers across London and a wide surrounding area. Some of them we installed. Many we did not.
-

One team for your chargers, inspection to aftercare.
We install and manage EV charging across London and the surrounding area, and we have been doing the maintenance side for as long as we have been installing. See how this works alongside apartment and communal charging, workplace charging and fleet and depot charging.
NAPIT Registered
Work carried out to BS 7671, by engineers with EV specific qualifications.
A Real Contract
A real management and maintenance contract, not a service description. What is included is published on this page, and so is what is not.
Annual Reports
Annual maintenance reports written and delivered to client management companies, covering what was inspected, what was found and what was done about it.
Already Under Contract
An installed base is already under contract across London and the surrounding area, so this is not a new line of business for us.
Accredited to the highest standard. Every project certified to the highest industry standards from design through to commissioning, signed off in-house by our own accredited team.
Taking on chargers we did not install. There is one step first.
We inspect and formally accept
Before a third party charger goes onto a maintenance contract we inspect it. We need to know what is actually there, what condition it is in, and whether the installation still meets current standards.
You get a documented position
What is there, what condition it is in, what still meets current standards and what does not. Chargers fitted before the open PEN protection rules came in are a common example.
Onto the contract
Accepted chargers go onto the package that fits the site. Even if you decide not to put them on a contract, you will know what you are holding.
The survey is quoted per site. Three sockets in a basement car park and a hundred across six locations are not the same job. Tell us what you have and where.
Most charger faults do not need a new charger.
Whoever fitted it, whatever the brand, we diagnose first and replace last. Logged, fixed and signed off by evon.
Request the maintenance packageApp or software
Fault logged
Charger works but the app is dead. No support line answers. You cannot see charging history or start a session remotely.
Resolved · with evon
Remote diagnostics, firmware updates and account recovery. Most software faults are cleared the same day without a site visit.
Engineer · evon Signed off · same day
Tripped supply
Fault logged
The charger died after a power cut and nobody knows which breaker feeds it. The unit shows nothing and the manual is long gone.
Resolved · with evon
We test the circuit, not just the unit. Supply faults are traced to the breaker, RCD or wiring and repaired to standard.
Engineer · evon Signed off · same day
Physical damage
Fault logged
A cracked case, water ingress or a severed cable. The unit still powers on, so nobody is sure if it is safe to use.
Resolved · with evon
We make it safe the same visit, then repair or replace on honest advice. If a repair is not economical we say so with a fixed price.
Engineer · evon Signed off · same day
Installer gone
Fault logged
The company that fitted the charger has stopped answering. Warranty paperwork, app access and spare parts all went with them.
Resolved · with evon
We adopt orphaned installations across every major brand. Access recovered, spares sourced and the unit brought under evon cover.
Engineer · evon Signed off · same day
Out of warranty
Fault logged
The manufacturer wants the original installer to handle the claim. Without them the warranty is worth nothing on paper.
Resolved · with evon
Where a claim is valid we handle it with the manufacturer directly. Where it is not, you get a plain price before any work starts.
Engineer · evon Signed off · same day
Paperwork
Fault logged
No certificates, no test records, no handover pack. Selling the property or making a claim turns into a search through old emails.
Resolved · with evon
Records rebuilt, tested and stored digitally against the site. Ready to share the day anyone asks for them.

EV charging work delivered across London and the South.
Choosing a maintenance package
Four packages. They differ on how often we visit, how fast we commit to being there, and how closely the site is watched in between.
Bronze
For sites where occasional downtime is not a problem.
ResponseBest effort
- One maintenance visit a year
- Basic monitoring
- Business hours support
Silver
For sites that need to be reliable without being critical.
ResponseGuaranteed 48 hours
- Visits twice a year
- 24 hour phone support
- Named account manager
Gold
For sites where charging availability affects how the business runs.
ResponseGuaranteed 24 hours
- Quarterly visits
- Real time diagnostics
- Monthly reporting
- Emergency callouts included
Platinum
For sites where downtime is not acceptable at all.
ResponseGuaranteed 4 hours
- Monthly visits
- Weekly reporting
- Senior account manager
- Rapid response team
Best effort, said plainly. On Bronze, response is best effort rather than a guaranteed time, and we would rather say that plainly than dress it up as an SLA.
How pricing works. A base fee plus a per socket rate, so a twenty socket car park is not charged as twenty separate visits. All prices exclude VAT.
The package document. Full scope, response times and pricing are set out in the package document. We are happy to send it.
What an EV charger maintenance contract covers
A maintenance contract exists to keep chargers working, not just to visit them. Someone checks the equipment on a schedule and watches it between visits.
Every charger reports its status to us continuously. When a unit drops offline or fails to start a session we see it, and on the higher tiers it raises a ticket automatically. Most of the time the fault is picked up and resolved before anybody on your site has noticed it.
What is included as standard.
Every evon package includes the same foundations, whatever tier you are on.
- Scheduled maintenance visits with full inspection and testing
- On site engineer labour
- Access to the monitoring platform
- Firmware updates
- Performance reporting
- A support line and a named route back to us
What is not included.
Published, so there are no surprises at the point you actually need us.
- Replacement hardware and parts, charged at cost plus labour
- Civil works, groundworks or structural changes
- Repairs caused by vandalism, theft or third party damage
- Electrical supply faults, which sit with your DNO
- Consumables such as cables replaced through wear or damage
- Software or connectivity problems caused by changes to your own network
- Chargers we did not install, until they have been inspected and formally accepted onto contract
Scheduled visits, monitoring in between, and a response time written into the contract.
Request the maintenance packageThe report your insurer asks for
Insurers and building compliance regimes expect evidence that EV charging equipment is inspected and tested. No single law sets the interval. Allianz, an insurer, publishes twelve months for EV charging points in its own engineering guidance, and most managing agents find out when a renewal questionnaire lands.
After every scheduled visit you get an EV Charging Condition Report. Named engineer, dated, referenced, and tested against BS 7671. It records every unit by serial number, the full electrical test results, the calibrated instrument used, photographs of the installation, and the date the next inspection falls due.
That is the document you forward. You do not have to chase it or write it yourself.
Reports written for your insurer. Every scheduled visit ends with an EV Charging Condition Report. We have issued them for sites insured with each of these.
Planned visits. Monitoring in between.
An annual inspection tells you the charger was working on the day somebody stood in front of it. The rest of the year is the part that matters, so the contract covers both: a schedule you can plan around, and somebody watching when nobody is on site.
Monitoring between visits
Every package includes access to our monitoring platform, so faults surface as data rather than as complaints. Chargers report their status continuously. When a unit drops offline, throttles itself or fails to start a session, it shows up on our side. On the higher tiers that turns into a ticket automatically. The platform covers EV charging, solar and battery storage in one place, so a site with more than one of those is not logging into three systems to work out what happened. Deeper monitoring runs on SolarEdge ONE.
Preventive: the planned visit
A schedule you can put in a budget. Every visit is a full inspection and test, and every visit ends with a written condition report.
Reactive: when one fails anyway
The practical difference is timing. Sites on planned inspection alone find out about a fault when somebody sends an email. Sites on monitoring find out first, and often before anyone has tried to plug in.
Included on every package
- Remote monitoring
- Fault detection
- Scheduled maintenance
- Condition reporting
- Firmware updates
- Performance reporting
Go deeper on any of it. Each of these is a full page rather than a paragraph. Written for whoever has to answer for the chargers, not for a search engine.
Do insurers require EV charger inspections?
Insurers expect evidence rather than requiring it by law, and the request usually arrives as a renewal questionnaire. Allianz publishes twelve months for EV charging points in its own engineering guidance. Here is what they actually ask for, and the one regulation that gets quoted at property managers wrongly.
How much does EV charger maintenance cost?
UK AC charger maintenance costs about £150 to £500 per unit per year. The spread is that wide because a single annual service and a contract with a guaranteed response are both sold as maintenance. What drives the number, and the line item that catches people out.
Who is responsible for maintaining communal EV chargers?
Whoever controls the installation, which for a block of flats is normally the freeholder, the management company or the managing agent. Not the residents. Four overlapping duties explain why it feels murkier than it is, plus one rule that does not apply to you.
How often should an EV charger be inspected?
There is no single legal interval, and anyone who says otherwise has usually invented it. Twelve months is where the industry has settled. Different parts of the installation run on different cycles, and the table most guidance leaves out is here.
What does an EV charger maintenance visit include?
A visual inspection, a full electrical test against BS 7671, functional testing, and a written report. If a visit does not produce measured results and a document at the end of it, what you have bought is a look rather than an inspection.
Does an EV charger need an EICR?
The charging circuit is part of the fixed installation, so it falls inside the EICR rather than outside it. Why an EICR on its own is not enough, and the finding that most often catches older installations out.
What happens if a charger breaks between visits?
Most faults happen between visits, which is why the schedule is only half of a contract. What gets fixed remotely, what needs an attendance, and the question worth asking about whether engineer labour is included or billed on top.
Do EV chargers need maintenance?
Yes, but less than most electrical plant. Almost nothing in a charger wears the way a boiler does. What actually fails is protective devices, firmware, the connection, the cable, and anything that lets water in.
Eight questions covering insurance, inspection intervals, cost, responsibility and what a visit actually includes.
