How Much Does an EV Charger Cost to Install in Medway?

Home EV charger installation has become one of the most consistently requested electrical jobs across Medway and the surrounding north Kent area. As the number of electric and hybrid vehicles on Medway’s roads grows year on year — driven by the shift away from new petrol and diesel, the expansion of company car EV schemes and the improving range of electric vehicles at all price points — the question of home charging has become less of a future consideration and more of an immediate practical priority for a growing proportion of Medway households.

The cost question is one most EV owners or prospective owners ask early — and the answer is more straightforward than it might initially seem. This post sets out realistic current prices for home EV charger installation in the Medway area, explains what affects the final figure, covers the main charger brands worth considering, and explains what the installation actually involves.

What Does an EV Charger Installation Cost in Medway?

Realistic current prices for a standard home EV charger installation from a registered Medway electrician:

• Standard 7kW smart charger installation, straightforward cable run: £650–£950
• 7kW smart charger, longer cable run or detached garage: £850–£1,350
• 7kW smart charger with consumer unit upgrade required: £1,250–£2,100
• Twin socket installation (two chargers, one property): £950–£1,500

These prices include the charger unit, all cabling, a dedicated circuit from the consumer unit, installation, testing and full certification under Part P. They assume the consumer unit has a spare way available — where it does not, a consumer unit upgrade is needed before the charger can be connected.

Medway sits broadly in line with the wider Kent market for electrical installation labour. For ME postcodes across Gillingham, Chatham, Rochester, Rainham, Strood and the surrounding area, the figures above represent realistic current pricing from a registered competent person scheme member.

What Affects the Installation Cost?

Cable Run Length and Route

The cable from the consumer unit to the charger position is the most significant variable in EV charger installation costs across Medway’s housing stock. On a property where the consumer unit is in the hallway and the driveway is immediately outside — common on the semi-detached stock of Twydall, Hempstead and the Rainham area — the cable run is short and the installation is at the lower end of the price range.

On properties where the car is parked at the rear but the consumer unit is at the front, or where the garage is a detached structure at the end of a long garden, the cable run is longer and in some cases needs to be buried underground. Underground cable buried beneath soft landscaping must be at 450mm depth and beneath driveways at 600mm — done correctly this adds groundwork cost but protects the cable from future disturbance.

Consumer Unit Capacity

A 7kW EV charger draws approximately 32 amps on a dedicated circuit — a significant load that requires a spare way in the consumer unit with appropriate protection. Many of Medway’s post-war properties have consumer units that are either at capacity or old enough that adding a new circuit requires a board assessment first. Where the existing board is a rewireable fuse board or an early MCB board without adequate RCD protection, we recommend a consumer unit upgrade before the EV charger circuit is added. Combining the two jobs in a single visit consistently reduces the overall cost compared with two separate call-outs.

Charger Brand and Specification

The charger unit itself is included in the prices above. The most commonly installed units across the Medway and north Kent area are Ohme, Hypervolt, Myenergi Zappi, Pod Point and Easee — each with different strengths depending on the vehicle, tariff and whether the property has solar panels. For homeowners on Octopus Energy’s Intelligent Go tariff, the Ohme integrates particularly well and schedules charging automatically during off-peak periods. For properties with solar PV, the Myenergi Zappi can be configured to prioritise charging from generated power rather than drawing from the grid. We advise on the right unit for your specific situation rather than defaulting to a single brand.

What Does the Installation Involve?

The Visit and Assessment

We carry out an assessment visit before confirming the final quote on any installation where the cable route is not straightforward. This confirms the consumer unit has capacity, establishes the cable route and any groundwork required, and ensures the quote reflects what the job actually involves with no hidden additions on installation day.

The Installation Day

A standard EV charger installation on a Medway semi-detached or terraced property with a straightforward cable run is typically completed in three to five hours. The process involves isolating the supply, running the new cable from the board to the charger position, mounting the unit, making all connections, testing the new circuit to BS 7671 standards and commissioning the charger through its associated app. The property is without power for approximately 30 to 60 minutes while the new circuit connection is made.

Certification and Building Control Notification

An EV charger installation is notifiable work under Part P of the Building Regulations. It must be carried out by a registered competent person who self-certifies and notifies building control on your behalf. An Electrical Installation Certificate is issued on completion — the document you will need when you come to sell the property.

Is a Home EV Charger Worth Installing in Medway?

For any Medway household with off-street parking and an electric or hybrid vehicle, a home charger is a straightforward investment that pays back quickly. Charging a typical electric vehicle at home on a standard tariff costs approximately £3–£6 for a full charge — compared with £15–£25 or more at public rapid charge points across the Medway area. On an EV-specific overnight tariff such as Octopus Intelligent Go, the cost drops to £1–£2 for a full charge. For Medway commuters driving regular daily mileages, this represents a saving of £1,500–£3,000 per year compared with equivalent petrol or diesel fuel costs.

The only practical limitation is off-street parking. For the majority of Medway’s semi-detached and detached housing stock — where driveways and garages are standard — this is not a constraint. For the older terraced properties without driveways in the streets closest to Gillingham and Chatham stations, the public charging network is the relevant alternative.
