DIRECT ANSWER
For many UK homes, a smart 7 kW charger with load management is the sensible starting point. Choose tethered for everyday convenience or untethered for a cleaner appearance and connector flexibility. Then compare tariff compatibility, solar support, cable reach, app reliability, warranty and total installed cost.
The installer must assess the property, supply and cable route; a charger cannot be selected safely from the car's battery size alone.
01 / FEATURES THAT MATTER
Prioritise the complete charging routine
Load management
Helps the installation respond to demand elsewhere in the property instead of treating the charger as an isolated appliance.
Reliable scheduling
Charging should fit the intended off-peak tariff without requiring a complicated routine every evening.
Tariff compatibility
Confirm whether the energy tariff controls the charger, vehicle or simply provides a fixed cheap period.
Cable reach
Measure the real parking positions and charge-port location. Do not assume every replacement car will place the port in the same corner.
Solar integration
Useful where the home already has solar or a realistic installation plan. Compare surplus-only and mixed-grid modes.
Warranty and support
Compare hardware, installation and labour cover separately, including who attends when the unit or app fails.
02 / TETHERED OR UNTETHERED
Convenience versus a cleaner installation
| Consideration | Tethered charger | Untethered charger |
|---|---|---|
| Daily use | Plug in immediately | Retrieve and connect a separate cable |
| Appearance | Attached cable remains visible | Cleaner when the cable is stored away |
| Connector flexibility | Normally fixed to one vehicle connector | Different suitable cables may be used |
| Replacement cable | May involve charger service or parts | Separate cable can normally be replaced independently |
| Best for | Frequent home charging and convenience | Tidy frontage or mixed connector requirements |
03 / INSTALLATION CHECKLIST
Questions the quotation should answer
- 1
What is included? Charger, cabling, protection, fixings, testing, certification, commissioning and app setup should be itemised.
- 2
Is the cable route standard? Confirm distance, wall drilling, surface type, trenching, consumer-unit work and any additional labour.
- 3
How is earthing handled? The installer should specify the compliant protection arrangement for the property and charger.
- 4
Is supply work required? Ask who deals with the distribution network operator, fuse changes, meter position or load limitations.
- 5
Who provides aftercare? Record separate contacts and warranty terms for the installer, charger manufacturer and app or connectivity service.
The property's electrical installation and intended cable route need an on-site or evidence-based assessment. Do not buy solely from a generic online estimate.
04 / UK GRANTS IN 2026
Up to £500 may be available for eligible installations
From 1 April 2026, several residential, landlord and workplace schemes increased to a maximum of £500 per eligible socket. Conditions, eligible hardware, installer requirements and closing dates differ.
Renters and flat owners
Up to 75% of buying and installation cost, capped at £500, subject to current eligibility including private off-street parking.
Cross-pavement solutions
Support may be available where an approved cross-pavement solution, such as a charging gully, is installed for eligible households.
Workplace Charging Scheme
Eligible organisations may receive up to £500 per socket for up to 40 sockets across their sites.
05 / COMPARE THE INSTALLED PRICE
Use the same specification for every quotation
- Give every installer the same photographs, distances and parking information.
- Compare the charger and installation price separately.
- List all assumptions and possible extras before accepting the quotation.
- Confirm the grant is included only when eligibility and process are clear.
- Check tariff support using the exact charger and vehicle model—not only the brand.
This is an example provider, not a recommendation to accept without comparing the complete installed quotation.

Frequently asked questions
What size home EV charger do most UK homes use?
Around 7 kW is the common starting point on a suitable single-phase domestic supply. Actual suitability depends on the property's electrical supply, existing demand, network requirements, vehicle and installation assessment.
Is a tethered or untethered home charger better?
Tethered is normally quicker for daily use because the cable is attached. Untethered looks tidier and can be more flexible between different vehicle connectors, but the separate cable must be retrieved and stored after use.
Can every electric car charge at 22 kW at home?
No. Approximately 22 kW AC generally requires a suitable three-phase supply, compatible chargepoint and a vehicle with an onboard charger that accepts it. Many UK homes and vehicles will not meet all three conditions.
Are UK home EV charger grants still available?
As reviewed in August 2026, eligible renters, flat owners, qualifying households using an approved cross-pavement solution, landlords and workplaces may receive support of up to £500 under the relevant scheme. Eligibility and closing dates must be checked on GOV.UK before ordering.
Should the charger be chosen before the electricity tariff?
Check both together. Some tariffs require a supported vehicle or charger, while others provide a fixed off-peak period without direct charger control. Confirm compatibility before committing to either product.
