How to Price an EV Charger Installation: Labour, Materials and Grant Deduction

Quick Answer: A typical 7kW domestic EV charger installation in 2026 prices £800–£1,400 fitted, comprising £350–£650 for an OZEV-approved smart charger, £80–£180 for cable and protective devices (Type B RCD or Type A + RDC-DD), and £350–£600 in labour for 4–7 hours of work plus DNO notification under ENA G100 and Part P certification. The OZEV EV chargepoint grant of £350 remains available only to flat dwellers and renters since the homeowner-facing scheme closed in March 2022. 22kW 3-phase installs run £1,400–£2,200 where 3-phase supply is already available; supply upgrades (single to three phase) add £800–£3,500.

Summary

The EV charger market has matured significantly since the OZEV homeowner grant closed in 2022. Charger unit prices have fallen 15–25% over four years as competition intensified — Project EV, Ohme, Easee, Wallbox, Andersen, Hypervolt, Pod Point and Zappi all sit within £80 of each other at the £400–£600 mid-tier. Where pricing variance now lives is in the supply-side work: cable run, supply assessment, DNO notification, and protective devices to comply with the IET Code of Practice for EV charging and BS 7671:2018+A2:2022.

The Smart Charge Point Regulations 2021 (SI 2021/1467) made smart functionality mandatory on all new domestic and workplace chargers from 30 June 2022. Default off-peak charging windows, randomised delay, demand-side response capability, and security requirements are baked into all OZEV-approved units. This isn't a choice; non-smart chargers cannot be installed for new domestic use.

The single most missed line item in EV charger quotes is RCD specification. Type B RCDs (which detect AC and smooth DC residual current up to 6mA) cost roughly 4× a standard Type A. Many modern chargers have built-in RDC-DD (Residual Direct Current Detection Device) that allows a Type A RCD upstream — significantly cheaper. Knowing which charger has built-in RDC-DD vs which requires Type B upstream is the difference between an £80 RCD and a £180 RCD in the bill of materials.

Detailed Guidance

Tethered vs untethered, 7kW vs 22kW

Tethered chargers have a built-in cable terminating in a Type 2 connector. Faster to use day-to-day, but the cable sits exposed in weather and is replaced when damaged (£140–£220 for a replacement cable). Untethered chargers have a Type 2 socket — the user supplies their own cable. £40–£80 cheaper, more flexible (suits visitors with different connector types), better for shared driveways.

7kW (32A single phase) is the UK domestic standard. Adds roughly 30 miles of range per hour of charging. Most cars charge overnight in 6–10 hours.

22kW (32A three-phase) is faster but requires 3-phase mains supply. Most UK domestic properties are single-phase. A single-to-three-phase upgrade involves the DNO replacing the cut-out and supply cable, costing £800–£3,500 in DNO charges plus 4–8 hours of additional electrician time. For most homes, the 22kW upgrade isn't economic — the car typically can't accept more than 7–11kW AC anyway (most domestic cars max at 7.4kW or 11kW AC onboard charger).

Earthing — PME/TN-C-S vs TT

The earthing system is the trickiest technical decision in EV charger installation. Most UK domestic supplies are PME (Protective Multiple Earthing) — the same conductor carries neutral and earth in the supply. PME is fine for most domestic loads but creates a specific risk for outdoor EV charging: if the supply neutral fails (open PEN conductor), the chassis of the charger and the connected vehicle become live at supply potential.

Three approaches:

  1. PME with Open PEN protection — the charger has built-in detection that disconnects on PEN fault. Most modern OZEV-approved chargers (Ohme, Project EV, Easee, Zappi, Wallbox Pulsar Plus) include this. Allowed under BS 7671 722.411.4.1 (iv).
  2. TT system — install a separate earth electrode (rod) at the charger location. Used where the charger doesn't have Open PEN protection or where the supply system is uncertain. Adds £80–£180 in earth rod and earthing conductor.
  3. Earth electrode on PME for added safety — install an additional rod even on a compliant Open-PEN-protected install. Belt-and-braces approach used in some commercial installs.

For a homeowner quote, the standard approach is PME with the Open PEN-detecting charger. TT is the fallback where the supply system can't be confirmed as safe.

RCD type — Type A with RDC-DD vs Type B

EV charging produces both AC and DC residual currents. Standard Type A or AC RCDs can be desensitised by smooth DC residual current above 6mA (BS 7671 722.531.3.101). Two compliant approaches:

  1. Type B RCD upstream — detects both AC and DC residual current. Costs £140–£220 supplied. Used when the charger doesn't have built-in DC fault protection.
  2. Type A RCD upstream + RDC-DD in charger — many modern chargers have a built-in 6mA DC fault detection device (RDC-DD or RDC-MD), allowing a Type A RCD upstream. Type A costs £30–£55. Net saving £100–£170.

Knowing which charger has RDC-DD built in is a quote-pricing skill. OZEV-approved chargers with built-in RDC-DD include most current Ohme, Easee, Project EV, Hypervolt, Wallbox, Andersen and Zappi models. Older or unbranded chargers often don't — and require a Type B RCD upstream.

DNO notification — ENA G100

Any electric vehicle supply equipment (EVSE) above 3.6kW (16A) must be notified to the DNO under Engineering Recommendation G100. The notification is online and free; the DNO confirms within 5–15 working days that the supply can support the additional load.

In rare cases (older properties on heavily-loaded street feeders, properties where existing demand is already at supply limit) the DNO may require a supply reinforcement before approving. This is unusual for domestic 7kW but more common for 22kW and multi-charger installs.

The G100 notification is the installer's responsibility. A clean quote shows it as a line item even though there's no fee — it's evidence of compliance and the customer wants to see it.

OZEV grant — who can still claim and how much

The OZEV (Office for Zero Emission Vehicles) grant landscape changed in March 2022 when the homeowner-facing chargepoint grant closed. Since then:

The renter/flat grant requires:

A clean quote for a renter or flat dweller shows: gross install £900–£1,300, less OZEV grant £350, net £550–£950.

Smart Charge Points Regulations 2021

The Electric Vehicles (Smart Charge Points) Regulations 2021 (SI 2021/1467) apply to all chargepoints sold in or installed in Great Britain from 30 June 2022 (and updated provisions from June 2023). Required functionality:

All OZEV-approved chargers comply by default. Cheap unbranded units sold via online marketplaces frequently don't comply — installing one for a paying customer in 2026 is a regulatory issue.

Cable run and physical install

Pricing the physical cable run:

For a typical garage-side installation with the CU directly inside the wall, total cable run is 5–8m and the physical install is straightforward. For a driveway charger 15–25m from the CU, the install can take a full day with trenching, cable pull, and termination.

Programme — typical half-day to one-day install

A typical 7kW domestic installation:

Total: 6–7 hours = comfortable single day. Installations with longer cable runs, supply upgrades, or 3-phase connection can stretch to 1.5–2 days.

Frequently Asked Questions

How much does it cost to install a home EV charger in the UK 2026?

£800–£1,400 fitted for a standard 7kW unit, with the charger costing £350–£650 supplied and labour £350–£600. 22kW chargers cost £1,400–£2,200 where 3-phase supply is already available; supply upgrades push prices to £2,500–£5,500. The OZEV grant for homeowners closed in March 2022 — only renters, flat dwellers and landlords still qualify for the £350 deduction.

Do I qualify for the OZEV £350 grant?

Only if you live in a flat or rent your home, or you're a landlord installing a chargepoint at a rental property, or your employer is installing one at a workplace. Homeowners with off-street parking who own their own home haven't been eligible since March 2022. Workplace charging is via the WCS, up to 40 sockets per business.

Can I get a 22kW charger at home?

Only if you have 3-phase mains supply. Most UK domestic properties are single-phase, so a 22kW charger requires a £800–£3,500 supply upgrade by the DNO. Even then, most cars accept only 7.4kW or 11kW on AC charging — so the 22kW capability is rarely fully utilised on a domestic install.

How long does the install take?

Most domestic 7kW installs are completed in 4–7 hours on site. Allow a full day for the installer to attend, including travel, paperwork, and DNO notification. Longer cable runs (>15m) or supply upgrades push the install to 1.5–2 days.

What's a smart charger and is it required?

A smart charger has internet connectivity, can schedule charging at off-peak times automatically, and complies with the Electric Vehicles (Smart Charge Points) Regulations 2021. Smart functionality is mandatory on all chargers sold in Great Britain since June 2022 — non-smart chargers cannot legally be installed for new domestic use. All OZEV-approved chargers are smart by default.
