A £244 Gap: Is the Simpson & Partners Home 7 Worth the Premium Over the Easee One?
These two chargers sit at opposite ends of a fascinating trade-off. The Easee One is the cheapest smart charger you can buy in the UK at £405, engineered for simplicity and packed with connectivity. The Simpson & Partners Home 7 costs £649 but brings premium British-made construction, a decade-long enclosure warranty, and three-phase support. One prioritises your wallet today; the other bets on longevity.
In a nutshell:
- Easee One: Best value smart charger with lifetime 4G, featherlight installation, £405
- Simpson & Partners Home 7: Premium aluminium build, 10-year enclosure warranty, three-phase capable, £649
Does the Easee One's £405 Price Tag Come With Compromises?
Honestly? Fewer than you'd expect. At 1.5 kg, the Easee One is absurdly light — your installer will thank you, and it opens up mounting options that heavier units can't manage. The built-in eSIM with lifetime 4G is a standout feature at this price. If your Wi-Fi doesn't reach the driveway (a surprisingly common problem), the Easee stays connected without you buying a range extender or running ethernet. That's a genuine running-cost advantage: no subscription fees, ever.
Where the Easee does cut corners is smart tariff integration. You can schedule charging windows manually through the app, but there's no native connection to Octopus Go or similar tariffs. If you're on a simple off-peak schedule, that's fine — set your window and forget it. But if you want the charger to automatically chase the cheapest half-hour slots on a variable tariff, you'll need to look elsewhere. Check our EV tariff comparison to see how much that could matter to your bill.
The other trade-off is the untethered design. There's no cable permanently attached — you plug in your own Type 2 cable each time. Tesla supplies one with every car, so this is a non-issue for most Tesla owners. Some people actually prefer it: no cable dangling on the wall, no cable management, cleaner look.
Is the Simpson & Partners Home 7's 10-Year Warranty Worth £244 More?
That warranty headline demands scrutiny. Ten years is extraordinary — the Easee One offers three years, and most competitors land between three and five. But read the fine print: the Simpson & Partners warranty covers the enclosure, meaning the anodised aluminium housing. It's not necessarily a blanket guarantee on every internal component for a full decade.
That said, the build quality is tangibly different. This is a UK-manufactured unit with anodised aluminium construction and multiple finish options, including Accoya wood panels. If your charger is front-and-centre on your house — visible from the street, next to the front door — the Simpson & Partners looks the part in a way the compact Easee doesn't try to. It's competing more with the Andersen A3 on aesthetics, but at £649 versus £995, it undercuts Andersen significantly while offering a longer enclosure warranty.
The Simpson & Partners also supports smart tariffs natively — Octopus Go, OVO Anytime, and EDF GoElectric — which the Easee lacks. Combined with solar compatibility and energy monitoring, it's a more feature-complete package for anyone building a smarter home energy setup.

Three-Phase Support: Does It Actually Matter?
The Simpson & Partners Home 7 can deliver 22kW on a three-phase supply. The Easee One is single-phase only, capped at 7.4kW. On paper, that's a massive difference. In practice, most UK homes have single-phase power, which means the Simpson & Partners will run at 7kW — actually 0.4kW slower than the Easee.
Where three-phase matters: if you're building a new home, renovating with a three-phase upgrade, or already have three-phase supply (more common in rural properties and some new-builds). In those scenarios, the Simpson & Partners future-proofs you without needing a charger swap later. For everyone else, it's a feature you're paying for but won't use.
Which Should You Buy?
Buy the Easee One if:
- You want the lowest upfront cost for a fully smart charger
- Reliable connectivity matters and your Wi-Fi is patchy — the lifetime 4G is unbeatable
- You prefer an untethered, minimal wall-mount look
- You're on a standard single-phase supply with no plans to change
Buy the Simpson & Partners Home 7 if:
- Build quality and longevity are your top priorities — you want a charger that still looks pristine in a decade
- You're on or plan to switch to a smart energy tariff like Octopus Go
- You have or plan to install three-phase power
- Aesthetics matter — you want finish options beyond standard black or white
For most Tesla owners on a single-phase supply who want a reliable, connected charger without overthinking it, the Easee One at £405 is the rational choice. It does the job, it stays connected, and it saves you £244 before you even plug in. But if you're the type who buys things once and expects them to last — and you value the smart tariff integration — the Simpson & Partners Home 7 makes a compelling case for spending more upfront.
