Hypervolt Home 3 Pro vs Andersen Quartz

The £47 gap — and the grant-shaped hole behind it

On paper, these two sit close together: the Hypervolt Home 3 Pro at £625, the Andersen Quartz at £672. A £47 difference. Barely a rounding error on a total install bill. But behind that gap is a structural difference that changes the real cost for many buyers — OZEV grant eligibility.

• Hypervolt Home 3 Pro — OZEV-approved, IP66 + IK10, up to 10m cable, three-year warranty extendable to five. The competent generalist.
• Andersen Quartz — seven-year warranty, eleven finishes, optional three-phase. Not confirmed OZEV-approved. The charger you buy when the wall matters as much as the watt.

The grant question changes everything

The Hypervolt Home 3 Pro is on the OZEV-approved list. For eligible renters and flat owners, the £500 grant brings the unit cost down to £125. The Andersen Quartz is not confirmed on that list — so qualifying buyers would pay the full £672, making the effective gap not £47 but £547. That is not a rounding error. If you qualify for the grant, the arithmetic is over before it starts.

For homeowners who do not qualify — which is most freehold houses — the grant is irrelevant and the comparison tightens back to £47. That is where the Andersen starts to make its case.

Seven years vs five — and what that £100 buys

The Quartz's headline advantage is its warranty: seven years, standard, no surcharge. The Hypervolt starts at three and extends to five for £100. Even with the extension, the Andersen covers you two years longer. For a device bolted to an exterior wall, cycling through British seasons, that difference is not trivial. The Hypervolt's IP66 + IK10 rating — the highest weather and impact protection in this class — argues the hardware may not need the longer warranty. The Andersen's IP65 is a step behind on paper, though still comfortably outdoor-grade. Whether you value the tougher enclosure or the longer promise is a matter of temperament.

Finish and flexibility — what the Andersen does differently

Eleven standard colours, optional Accoya wood and carbon-fibre inserts, a compact 286 × 172 × 110 mm footprint. The Quartz is an Andersen product, and Andersen products exist because some people care what their driveway wall looks like. The Hypervolt answers this with interchangeable covers in Ultra White, Space Grey, and Ultra Black — pleasant enough, but three options against eleven is not a close contest.

The Quartz also offers a socketed (untethered) variant and an optional 22kW three-phase upgrade for £195. The Hypervolt is tethered only and single-phase only. If your home has a three-phase supply — or might get one — the Andersen keeps the door open. The Hypervolt does not.

Smart features and tariff integration

Neither charger is the tariff-chasing specialist. Both do scheduled charging through their apps; both integrate with Intelligent Octopus Go. The Andersen adds OVO Charge Anytime support. Neither handles half-hourly variable rates like Octopus Agile with the precision of an Ohme Home Pro — if that is your priority, you want a different comparison entirely. See the Ohme vs Andersen Quartz page for that angle.

Both include a CT clamp for basic solar diversion. Neither matches the Zappi GLO's surplus-only Eco+ mode. For straightforward off-peak scheduling on Octopus Go or EDF GoElectric, both chargers do the job without fuss.

Cable length — a practical fork

The Hypervolt's 10m tethered option is the longest on any charger in the catalogue. If your parking spot sits far from the consumer unit, that reach matters more than any finish or warranty clause. The Andersen tops out at 8.5m (for an extra £99 over the base 5.5m). Not short by any means — but 1.5 metres can be the difference between reaching the charge port and not.

Which to buy

Buy the Hypervolt Home 3 Pro if:

• You qualify for the OZEV grant — the effective price drops to £125, and the comparison ends here.
• You need a cable longer than 8.5m — the 10m option has no rival at this price.
• You want the toughest enclosure — IP66 + IK10 is the best weather and impact rating in the field.

Buy the Andersen Quartz if:

• Warranty length is your priority — seven years, no surcharge, no extension to arrange.
• You want to match the charger to your house — eleven colours and premium insert options.
• You may upgrade to three-phase — the £195 22kW option keeps that path open.

For most buyers, the Hypervolt is the more practical choice. It costs less, has OZEV approval, offers a longer cable, and takes a harder knock. The Andersen Quartz earns its £47 premium for a specific buyer — one who values a seven-year warranty, wants the charger to look a certain way on the wall, and does not qualify for the grant. Outside that profile, the Hypervolt is the one to fit.
