Overview

What this service is, and who it's for.

Straight explanation, no jargon padding, so you can decide whether it's the right call before you even ring us.

What it is: An EV charger installation is far more than fitting a box on the wall. It's a dedicated circuit from your consumer unit, sized correctly for the charger's current draw, protected with the right RCD/RCBO devices under 18th Edition regulations, tested to BS 7671, and, where required, configured for load management so it plays nicely with your existing supply. We install Ohme chargers because we're accredited by the manufacturer, but we can advise on other units too.
Who it's for: Homeowners plugging in their first EV, landlords adding a charger to a rental to future-proof the property, fleet managers rolling out multi-bay charging at a depot, and commercial premises adding customer or staff charging. We handle single-unit domestic jobs and multi-circuit commercial arrays with the same level of documentation.
When you need it: Book the survey before your car is delivered so the charger is live on day one. If you've bought a used EV and you're currently trickle-charging off a 3-pin socket, that's a fire risk under sustained load, a proper 7kW installation is the right fix.
Why professional matters: A properly installed EV charger is a fixed electrical installation subject to Part P of the Building Regulations. Non-certified installs invalidate insurance, can void the charger's warranty, and, in a fault condition, can back-feed the grid. NAPIT accreditation means the work is notified and certified through a recognised competent-persons scheme.

What happens if you leave it

The cost of putting it off is rarely just money.

Charging a modern EV off an unrated socket or via a DIY install is one of the fastest ways we see kitchens and garages catch fire. The load is high, sustained and overnight, exactly the profile a domestic ring final circuit isn't designed for.

What can go wrong

Overheated 3-pin sockets and melted plug housings from sustained 10A+ draw.
Nuisance tripping of the whole property whenever the car plugs in, usually at 2am.
Voided car and charger warranties because the install wasn't notified or certified.
Home insurance disputes after any fault, because the work wasn't Part P compliant.
Costly retrofits when a self-installed charger fails the next EICR or house sale survey.

Common mistakes we see

Buying the cheapest charger online without checking supply capacity or tail size.
Assuming the existing consumer unit can take another high-current circuit without an upgrade.
Skipping earth-electrode or PEN-fault protection on a TN-C-S supply.
Running cable in trunking that isn't rated for the ambient temperature behind an insulated wall.
Trusting a general handyman rather than a NAPIT-accredited EV installer.

How we work

A five-step system, so nothing gets missed.

The same discipline we run on a single-socket call-out and a full commercial fit-out. Predictable, documented, tidy.

01
Inspection
Free on-site survey. We look at the existing installation, the space and the outcome you need, no pressure, no obligation.
02
Diagnosis & fixed quote
We scope the work, agree the spec in plain English and give you a fixed-price written quote with no hidden extras.
03
Booked-in works
We turn up when we say we will, protect the space with dust sheets and keep disruption to your day to a minimum.
04
Testing & verification
Every circuit is tested to BS 7671 (18th Edition). Nothing gets signed off until the readings are right.
05
Certification & handover
You get NAPIT-backed certification, a tidy handover and a clear explanation of what's been done and why.

Benefits

What you actually get from doing this properly.

Charge overnight in hours, not days

A 7kW dedicated circuit typically adds 25–30 miles of range per hour, a full charge while you sleep, versus 2+ days on a 3-pin.

Safer than a plug-and-play trickle lead

Dedicated cable, correct protection and manufacturer-approved earthing remove the sustained-load fire risk.

Lower cost per mile

Overnight home charging on an EV tariff is a fraction of the cost of a public rapid charger, and load-managed setups keep you inside your supply capacity.

Ohme app-controlled scheduling

Charge on the cheapest half-hour slots automatically, we set the app up with you on handover.

Future-proofed installation

We size cable and protection with headroom, so upgrading to a bigger battery or a second vehicle later is a small job, not a rewire.

Certified and warranty-protected

You get NAPIT certification for building control and the manufacturer warranty is kept intact because the install is notified.

Chargers we install

We're Ohme-accredited and install the full Ohme range, Home Pro, ePod and commercial variants, plus we can advise on tethered vs untethered options depending on your parking layout. Ohme units integrate directly with intelligent tariffs like Octopus Intelligent Go, which means the charger, not you, decides when to pull power at the cheapest price. For workplaces, we design and install multi-charger arrays with load balancing so you don't need to upgrade the incoming supply.

Cable, containment and earthing

We use appropriately sized SWA or twin-and-earth depending on route (external run vs internal), routed neatly through cable trunking or clipped direct where visible. Earthing on a TN-C-S supply is handled either with the charger's built-in PEN-fault protection (Ohme units are RDC-DD Type A and include this) or with a dedicated earth electrode where the supply topology requires it. We check earth loop impedance before signing anything off.

Consumer unit and supply considerations

Not every consumer unit can take another 32A circuit. If you have an older split-load board without RCBO protection on every circuit, or an unfused board sat close to its rated capacity, a consumer unit upgrade is often the right first step. We assess this at the free survey, and if it's needed we'll quote it as part of the EV package rather than surprising you on the day.

Domestic vs commercial installs

Domestic installs are typically a single 7kW charger on a dedicated circuit from the consumer unit, tested and certified. Commercial installs, up to 50 circuits in the case of some depots we've worked on, need a proper load study, distribution board sizing, containment (Unistrut, tray or catenary), and often a DNO notification for the incoming supply. Every install is quoted fixed after a site survey, based on charger count, containment and any supply upgrades, so you get one number before we start.

What we don't do, and why we're upfront about it

We are not OZEV approved, so we cannot process the government EV homecharge grant on your behalf. If you specifically need a grant-assisted install, we'll tell you at the survey. Everything else, accreditation, certification, insurance, is in place. We'd rather be straight about that than mislead you into paperwork we can't file.

Answers

Common questions on this service.

Still unsure? Ring us on 07491 966787 , surveys and quotes are free.

How much does EV charger installation cost?+

Every EV install is quoted fixed after a free site survey, single-charger domestic through to multi-circuit commercial arrays, with all materials (charger, cable, protection devices, consumer unit accessories) itemised.

How long does the installation take?+

A straightforward domestic install with the consumer unit in the garage next to the parking spot is typically a half-day. If we need to run cable through the loft, around the outside of the property, or upgrade the consumer unit, it usually stretches to a full day. Commercial arrays are scoped and scheduled at the survey.

Do I need to upgrade my consumer unit?+

Not always, many modern 18th Edition boards have spare capacity and RCBO protection ready to accept a new EV circuit. Older boards, or ones already close to their rated load, sometimes need upgrading first. We'll tell you honestly at the survey, and if an upgrade is needed we quote it as part of the same job.

Are you Ohme accredited?+

Yes, we're accredited by Ohme, which means we can install their full range and register the units so the warranty stays intact. Our EV work is NAPIT-accredited too, so every install is notified and certified through the competent-persons scheme.

Can you install a charger if I don't have off-street parking?+

In most cases, no, running cable across a public pavement isn't legal without a specific licence from the local authority. If your parking is on your own driveway or in a private car park, we're fine to install. If you're borderline, ring us and we'll talk it through.

Do you handle OZEV grant paperwork?+

No, we are not OZEV approved, so we can't file the grant paperwork on your behalf. If OZEV eligibility is essential for you, we'll tell you at the enquiry stage rather than take the job on and disappoint you later.

What happens if the charger develops a fault later?+

Ohme units are covered by the manufacturer's warranty for the period stated at purchase, which stays valid because the install is notified. If the fault is in the fixed wiring rather than the unit, call us on 07491 966787 and we'll diagnose and fix it at our agreed call-out rate.

Can you install multiple chargers at a business premises?+

Yes, we install multi-charger arrays with load management, distribution board work, containment and, where needed, DNO liaison for supply upgrades. Ring us with the site details and rough number of bays and we'll arrange a free commercial survey.

Are you qualified and insured?+

Yes. H&H Electrical is NAPIT registered, our EV work is NAPIT-accredited and Ohme approved, and we carry public liability, employers' liability and indemnity insurance in full.

Do you cover my area?+

We cover Chepstow, Newport, Bristol & across South Wales, the South West, Cardiff, Bath, Gloucestershire, Caldicot, Magor and Undy. Ring us if you're just outside, most of the time we can still help.

How do I pay?+

Bank transfer or cash. We don't take card. Small jobs are call-out plus materials; larger jobs are quoted at a fixed price up front so you know the total before we start.
