Hypervolt Home 3 Pro vs Simpson & Partners Home 7

£24 apart, built on different bets

Two UK-manufactured chargers, near-identical pricing, quite different ideas about what matters. The Hypervolt Home 3 Pro costs £625 and bets on physical toughness — IP66 + IK10, the highest weather and impact rating in the residential market. The Simpson & Partners Home 7 costs £649 and bets on longevity and aesthetics — a 10-year enclosure warranty wrapped in anodised aluminium with finish options that belong in an interiors magazine.

• Hypervolt Home 3 Pro — the competent all-rounder. Tougher build, longer cable options, bigger installer network. £625.
• Simpson & Partners Home 7 — the design-led outsider. 10-year enclosure warranty, three-phase option, premium finishes. £649.

The warranty question — and the asterisk

Simpson & Partners leads with its 10-year warranty, and rightly so. No other home charger on the UK market matches it. But the detail matters: that decade covers the enclosure — the aluminium shell — not the electronics inside it. The internals get three years, which is exactly what the Hypervolt offers as standard (extendable to five for £100).

So the Simpson & Partners promise is this: the thing on your wall will still look good in 2036. That is a genuine differentiator if curb appeal matters to you — and for a front-of-house install on a stone cottage, Cotswolds Green or Accoya wood trim might be the deciding factor. But if your charger lives in a side return or a garage, the enclosure warranty is less relevant than the electronics warranty, and on that measure they are level.

The Hypervolt's counter-argument is its IP66 + IK10 rating. IP66 means full protection against powerful water jets; IK10 means it can take a 20-joule impact — roughly equivalent to a 5 kg weight dropped from 40 cm. The Simpson & Partners Home 7 carries IP54, which handles rain and splashing but is a step below. For exposed, unprotected mounting positions, the Hypervolt is the more resilient unit.

Three-phase, untethered, and the features the Hypervolt cannot match

The Simpson & Partners Home 7 offers a 22kW three-phase option. The Hypervolt does not — it is single-phase only, capped at 7.4kW. For the vast majority of UK homes on a single-phase supply, this is irrelevant. For the small number with three-phase power — or those planning a supply upgrade — it is a hard differentiator. The only other chargers in this price range offering 22kW are the Zappi GLO at £599 and the Wallbox Pulsar Max at £513.

Simpson & Partners also sells an untethered version — a wall-mounted socket without a permanently attached cable. Useful if you charge multiple vehicles with different connectors, or if you simply prefer a cleaner wall. The Hypervolt is tethered-only, though it compensates with cable length options: 5 m, 7.5 m, or 10 m. That 10-metre option is the longest available on any UK home charger, and for driveways where the car parks far from the consumer unit, it removes the need for cable management gymnastics.

Smart features and tariff support

Both chargers handle the basics — app scheduling, energy monitoring, solar compatibility. Neither is the tariff-chasing specialist that the Ohme Home Pro is; if half-hourly Octopus Agile optimisation is important to you, the comparison you want is Ohme Home Pro vs Hypervolt Home 3 Pro.

On fixed off-peak tariffs — Octopus Go at 8.5p/kWh, EDF GoElectric at 6.99p/kWh — both chargers do the job with a simple timer. The Simpson & Partners Home 7 also supports Intelligent Octopus Go scheduling directly, which gives it a modest edge over basic timer-only operation.

The Hypervolt includes a CT clamp for solar diversion at no extra cost. The Simpson & Partners lists solar compatibility but without the same out-of-the-box CT clamp inclusion. Neither charger rivals the Zappi GLO's surplus-solar logic — if solar diversion is the priority, that is the comparison to make.

The verdict

Buy the Hypervolt Home 3 Pro if:

• Your install is exposed to weather, impacts, or both — IP66 + IK10 is the toughest residential rating available
• You need a cable longer than 5 metres — the 7.5 m and 10 m options are unmatched
• You want a wider installer network and phone support that picks up quickly

Buy the Simpson & Partners Home 7 if:

• You have or plan a three-phase supply and want 22kW charging
• The charger will be visible from the street and aesthetics matter — the finish options justify the price
• You prefer an untethered socket for multi-vehicle flexibility

For a single-phase home where the charger mounts on a side wall or in a garage, the Hypervolt is the more practical £625 you will spend. It does nothing spectacularly, but it does everything competently, and it will take more punishment than anything else at this price. The Simpson & Partners earns its £24 premium only when its specific advantages — three-phase, untethered, or a finish your architect would approve of — are the ones you need. If the Andersen A3 at £900 made you wince but you still want front-of-house design quality, the Andersen A3 vs Simpson & Partners comparison is worth a look — the Simpson & Partners undercuts it by £251 with a longer enclosure warranty.
