Simpson & Partners Home 7 vs Wallbox Quasar 2

> V2G boundary: A “V2G-ready” label or ISO 15118 support does not by itself provide bidirectional power conversion, export approval or a live energy service. Confirm the compatible car, genuinely bidirectional hardware, certified complete system, installer, service and network approval before assigning value to the claim. Read the UK V2G explainer.

A home charger versus a home energy thesis

These two products share a wall-mounting bracket and a Type 2 plug — and almost nothing else. The Simpson & Partners Home 7 is a £649 AC charger built from anodised aluminium in the UK, with a 10-year enclosure warranty and a tethered or untethered option. The Wallbox Quasar 2 is a £6,100 bidirectional DC unit that can push power back from your car's battery into your house or the grid. The gap between them is £5,451.

• Simpson & Partners Home 7 — a premium-finish, UK-made AC wallbox. Charges your car at 7kW (single-phase) or 22kW (three-phase). Does the job and looks good doing it.
• Wallbox Quasar 2 — a bidirectional DC charger offering V2H and V2G via CCS2. Pre-registration only in the UK. Requires a compatible car, a specialist installer, and a DNO G99 application.

This is not a like-for-like contest. It is a question of category.

What the £5,451 buys — and what it doesn't

The Quasar 2's party trick is bidirectional DC charging at up to 12.8 kW. In theory, your car becomes a home battery: draw from it during peak hours, export to the grid when rates are high, charge from solar during the day. On paper, the economics are attractive — a 77 kWh car battery dwarfs a typical 10 kWh home storage unit, and a V2G tariff could pay you to export.

In practice, the list of caveats is long. The car must support CCS2 bidirectional DC — today, that means the Kia EV9 and a handful of others. Most UK Teslas cannot use this feature at all. Installation runs £1,500–£3,000 on top of the £6,100 unit price, pushing the all-in cost past £7,600. You need a DNO G99 application, which takes 30–60 working days and may come with a G100 export cap. The warranty is 3 years, with UK terms still unconfirmed. And the unit itself is not yet on open sale — it is pre-registration only as of April 2026.

The Simpson & Partners Home 7, meanwhile, arrives at your house for £649 (or £149 after the £500 OZEV grant for eligible renters and flat owners). Install runs £400–£600. Total outlay: roughly £1,050–£1,250 for most buyers. It charges every EV on sale in the UK, via a standard Type 2 connector, at the same 7kW rate as every other single-phase AC wallbox. Its enclosure warranty — 10 years — is the longest on the domestic market, though the internal electronics are covered for 3 years.

Who the Quasar 2 is actually for

A small, specific group. You need all of the following: a bidirectional-compatible car, a V2G export tariff (or confidence one is coming soon), a willingness to navigate the G99 process, and enough faith in the technology to spend £7,600+ on a product whose UK availability is still marked "keep me updated."

If that describes you, the Quasar 2 is hardware to investigate with the car maker, installer and energy service. The Indra Smart PRO is a one-way AC charger. The Zaptec Go 2 publishes ISO 15118 support, but Zaptec says it cannot currently be registered as a UK V2G installation and still needs a certified complete system.

The Simpson & Partners Home 7 on its own merits

Strip away the Quasar 2 comparison and the Home 7 stands well in its own bracket. It is £251 cheaper than the Andersen A3 — the obvious design rival — and offers a longer enclosure warranty. It supports 22kW three-phase charging, unusual at this price. Finish options include Accoya wood and Cotswolds Green, which is a gentler proposition for a period cottage than a glossy plastic pod.

The trade-offs are real. The installer network is smaller than Ohme's or myenergi's — confirm a local fitter before ordering. The app is functional rather than polished. And if smart tariff integration matters more than build quality, the Ohme Home Pro at £539 is the stronger pick for half-hourly optimisation on Octopus Agile.

The verdict

Buy the Simpson & Partners Home 7 if:

• You want a well-made, UK-built charger with the market's longest enclosure warranty
• You value how the unit looks on the front of your house
• You need a standard AC wallbox that works with every EV, every tariff, no complications

Buy the Wallbox Quasar 2 if:

• You own (or are about to buy) a CCS2-bidirectional car like the Kia EV9
• You have — or expect to have — a V2G export tariff that makes the hardware economics work
• You accept the pre-registration wait, the G99 process, and the specialist install cost

For the overwhelming majority of UK EV owners, the decision is not close. The Simpson & Partners Home 7 charges your car, looks handsome on a wall, and costs £649. The Quasar 2 is an interesting piece of energy infrastructure for a future that has not quite arrived. Buy the charger you need today.
