Hypervolt Home 3 Pro vs Simpson & Partners Home 7: Safe Bet or Hidden Gem?

The Proven All-Rounder vs the Underdog With a 10-Year Warranty

Choosing a home EV charger in the UK usually means picking between the same handful of well-known names. But every so often, a less familiar brand turns up with a spec sheet that makes you do a double-take. That's exactly the situation when you pit the Hypervolt Home 3 Pro — one of the most popular and widely reviewed chargers on the market — against the Simpson & Partners Home 7, a premium British-built unit that most drivers haven't even heard of yet.

On paper, these two are remarkably close in price, both manufactured in the UK, and both OZEV-approved. But dig into the details and you'll find genuinely different philosophies. The Hypervolt is a polished, feature-rich all-rounder with a huge installer network and thousands of happy owners. The Simpson & Partners Home 7 counters with an extraordinary 10-year enclosure warranty, anodised aluminium construction, and — crucially — three-phase support at a price where you'd normally only get single-phase. So which one earns a spot on your wall?

In a nutshell:

• Hypervolt Home 3 Pro (£690): The do-everything smart charger with excellent solar integration, best-in-class durability ratings, and a proven track record backed by rapid UK-based customer support.
• Simpson & Partners Home 7 (£649): A premium-feeling charger with the longest warranty on the market, distinctive design options including Accoya wood finishes, and rare three-phase capability for future-proofing.

Spec Comparison

Smart Tariff Integration

Both chargers support smart tariff scheduling, which is essential if you want to take advantage of off-peak rates on tariffs like Octopus Go (7.5p/kWh between 00:30 and 04:30) or Octopus Intelligent Go (~7p/kWh). At those rates, charging a typical 60kWh Tesla battery from 20% to 80% costs roughly £2.50–£2.70 — compared to over £15 on a standard variable tariff.

The Hypervolt Home 3 Pro handles this through its own app, which lets you set charging schedules and integrates with various energy tariffs. As heatable.co.uk notes in their review, the app offers tariff optimisation for cost savings alongside energy monitoring. The Simpson & Partners Home 7 explicitly lists support for Octopus Go, OVO Anytime, and EDF GoElectric through its S&P app.

Neither charger matches the Ohme Home Pro's direct API integration with Octopus Intelligent Go (which can unlock extra off-peak hours), but both are perfectly capable of scheduled off-peak charging — which is how most UK drivers save the bulk of their money. For the vast majority of smart tariff users, either charger will do the job.

Solar Integration

This is where the Hypervolt pulls ahead meaningfully. The Home 3 Pro includes a CT clamp for solar integration out of the box — no extra hardware required. It offers three solar charging modes (Boost, Eco, and Super Eco) that let you choose how aggressively you prioritise surplus solar energy. As topcharger.co.uk highlights, this enables maximised solar self-consumption, which is increasingly important as more UK homeowners pair solar panels with their EV chargers.

The Simpson & Partners Home 7 is listed as "solar compatible," but the data doesn't indicate the same level of built-in solar diversion functionality or included CT clamp hardware. If you've got a 4kW solar array on your roof and want your EV to soak up every spare watt on a sunny afternoon, the Hypervolt's dedicated solar modes give you noticeably more control.

That said, neither charger matches the myenergi Zappi's Eco+ mode for pure solar diversion sophistication — but the Hypervolt gets you most of the way there without the Zappi's higher price tag.

Build Quality, Design, and Weatherproofing

Both chargers are manufactured in the UK, which is a genuine point of pride and means better access to support and spare parts. But they take different approaches to durability.

The Hypervolt Home 3 Pro boasts an IP66 rating (fully dust-tight and protected against powerful water jets) combined with IK10 impact resistance — the highest rating on the mechanical protection scale. As electriccarguide.co.uk puts it, "it's pretty hard to damage." It's also compact at 270mm × 170mm × 110mm and weighs just 4.5 kg, with interchangeable colour covers in Ultra White, Space Grey, and Ultra Black. You also get a choice of three cable lengths (5m, 7.5m, or 10m), which is genuinely useful if your parking spot isn't right next to your consumer unit.

The Simpson & Partners Home 7 counters with anodised aluminium construction and distinctive finish options including Accoya wood — a sustainably sourced hardwood that gives the unit a genuinely premium, architectural feel. It's available in both tethered and untethered versions, which is a flexibility the Hypervolt doesn't offer. However, its IP54 rating is notably lower — it's protected against splashing water from any direction, but not the powerful jets that IP66 handles. In a sheltered installation this won't matter, but if your charger is fully exposed to driving rain, the Hypervolt's weatherproofing is objectively superior.

Power and Charging Speed

On a standard UK single-phase supply, both chargers deliver similar performance: 7kW (Simpson & Partners) versus 7.4kW (Hypervolt). That translates to roughly 8.5 hours for a full 0–100% charge on a 60kWh battery with the Simpson, or about 8.1 hours with the Hypervolt. In practice, you'll barely notice the difference overnight.

Where the Simpson & Partners Home 7 has a genuine ace up its sleeve is three-phase support. If you have (or plan to install) a three-phase supply, it can deliver 22kW — cutting that same charge to approximately 2.7 hours. Three-phase is rare in UK homes today (under 5% of properties), but it's increasingly common in new-builds and can be retrofitted for £1,000–£3,000. If you're future-proofing or already have three-phase, this is a significant advantage that the Hypervolt simply cannot match.

Price and Value

The Simpson & Partners is £41 cheaper at the unit level, which isn't a meaningful difference. The real value gap is in what you get for that money. The Hypervolt gives you superior weatherproofing, proven solar diversion with an included CT clamp, Bluetooth connectivity alongside Wi-Fi, and multiple cable length options. The Simpson & Partners counters with a 10-year enclosure warranty (versus 3 years standard on the Hypervolt, or 5 years for an extra £100), three-phase capability, the option of an untethered socket version, and premium materials like anodised aluminium and Accoya wood.

Both represent strong value. The question is whether you prioritise proven features and community support, or long-term warranty coverage and future-proofing.

Who Should Buy Which?

Buy the Hypervolt Home 3 Pro if:

• You have solar panels and want built-in solar diversion with multiple charging modes and an included CT clamp
• You want the toughest weatherproofing available (IP66 + IK10) for an exposed installation
• You value a large installer network, extensive online reviews, and 5-second average customer support response times
• You need a longer cable — the 7.5m and 10m options are a lifesaver for awkward driveways
• You want a proven, widely trusted charger that does everything competently

Buy the Simpson & Partners Home 7 if:

• You want the longest warranty on the market — 10 years on the enclosure is unmatched
• You have three-phase power (or plan to upgrade) and want 22kW charging capability
• You prefer a distinctive, premium aesthetic with options like Accoya wood finishes
• You want the flexibility of choosing between tethered and untethered versions
• You're comfortable with a smaller brand in exchange for excellent build materials and future-proofing

Our recommendation: For most UK homeowners on a standard single-phase supply, the Hypervolt Home 3 Pro is the safer, smarter pick. Its solar integration is more developed, its weatherproofing is best-in-class, and the sheer volume of positive reviews and installer experience means fewer surprises. But the Simpson & Partners Home 7 is a genuinely compelling alternative — particularly if you have three-phase power or simply want a charger that's built to last a decade with that remarkable warranty to back it up. It's an underdog that deserves to be on your shortlist.
