Hypervolt Home 3 Pro vs CTEK Chargestorm Connected 3: The £396 between domestic and industrial

A home charger and a car-park unit walk onto the same wall

These two products occupy different planets. The Hypervolt Home 3 Pro at £690 is a domestic smart charger — app-controlled, tariff-aware, built for a driveway. The CTEK Chargestorm Connected 3 at £1,086 is an industrial-grade charging station that happens to be OZEV-approved for residential use. The £396 gap is wide, and the install cost gap is wider still.

• Hypervolt Home 3 Pro — £690. Smart tariff scheduling, solar diversion via CT clamp, IP66, up to 10m tethered cable, 3-year warranty extendable to 5.
• CTEK Chargestorm Connected 3 — £1,086. Native three-phase 22kW, MID-approved meter, built-in Type B MRCD, OCPP 1.6-J and 2.0.1, 5-year warranty. No first-party tariff integration.

Why the CTEK costs £396 more — and who that serves

The CTEK's price reflects hardware most home chargers omit. A built-in MRCD Type B means your installer doesn't need to fit a separate DC fault protection device — that alone saves £100–£200 on parts and labour. The MID-approved energy meter is Eichrecht-compliant, relevant if you need legally defensible billing (workplace recharging, landlord cost recovery). And the 22kW three-phase output is genuine: on a three-phase supply, it charges roughly three times faster than any single-phase unit.

The problem is context. Fewer than 5% of UK homes have three-phase power. On a standard single-phase supply, the CTEK delivers the same 7.4kW as the Hypervolt — but weighs 24kg to the Hypervolt's 4.5kg, costs £396 more for the unit, and runs £900–£1,300 for installation against the Hypervolt's £400–£600. You are paying a premium for capacity you cannot use.

If you *do* have three-phase — or you're upgrading your supply as part of a broader project — the CTEK earns its place. Its nearest rival in that niche is the Zaptec Go 2 at £500, which also supports three-phase but lacks the MID meter and built-in Type B protection. The CTEK is the more complete package for commercial or semi-commercial settings.

Smart tariff control: one has it, one does not

This is where the comparison tilts hard. The Hypervolt integrates directly with smart tariffs — set it to charge during Octopus Go's 00:30–05:30 window at 8.5p/kWh, or let it track Octopus Agile pricing, and it handles the rest through its own app. Solar owners get a CT clamp in the box for surplus diversion. Nothing exotic, but it works without fuss.

The CTEK has no first-party app for tariff scheduling. It speaks OCPP, so you can bolt on a third-party platform like Monta — but that adds complexity, and critically it cannot participate in Octopus Intelligent Go or OVO Charge Anytime, both of which require direct charger integration. For a home user chasing the cheapest possible pence-per-kWh, this is a significant gap. The Hypervolt slots into the UK tariff ecosystem; the CTEK stands outside it.

Build quality and warranty

Both units carry IK10 impact ratings. The Hypervolt goes further on weather sealing — IP66 against the CTEK's IP54 — meaning it handles direct jets of water rather than just splashes. For a charger mounted on an exposed wall in a British winter, that difference has practical value.

The CTEK's 5-year warranty is standard. The Hypervolt starts at 3 years but extends to 5 for £100, bringing total outlay to £790 — still £296 less than the CTEK before installation.

The Hypervolt's tethered cable runs up to 10 metres, the longest option on any home charger in our charger index. The CTEK is untethered with a 4m fixed tail to a Type 2 socket, so you supply your own cable — adding £50–£150 and one more thing to coil up after each session.

The verdict

Buy the Hypervolt Home 3 Pro if:

• You have a single-phase supply — which is almost every UK home
• You want smart tariff scheduling without third-party platforms
• You value a 10m tethered cable, IP66 weatherproofing, and a sub-£700 unit price

Buy the CTEK Chargestorm Connected 3 if:

• You have or are installing a three-phase supply and want 22kW charging
• You need MID-approved metering for billing or cost recovery
• You require OCPP 2.0.1 compliance for a managed charging network

For the typical UK home — single-phase, one car, an Octopus or OVO tariff — the Hypervolt is the obvious choice at £396 less. The CTEK is an impressive piece of engineering, but it is engineering for a problem most domestic buyers do not have. If three-phase is your reality, compare the CTEK against the Zaptec Go 2 at £500 before committing to the higher spend. If single-phase is your reality, the Hypervolt does the job and leaves £396 in your pocket.
