Two Niche Chargers, Two Very Different Bets
This is an unusual comparison. The GivEnergy EV Charger and the Simpson & Partners Home 7 aren't mainstream picks like the Ohme or Tesla Wall Connector. They're both specialists — one built around home energy storage, the other around premium hardware and longevity. Choosing between them depends almost entirely on what you've already got installed at home and what you value most.
In a nutshell:
- GivEnergy EV Charger (£478): The obvious pick if you have a home battery. Charges your Tesla from stored energy, not just live solar.
- Simpson & Partners Home 7 (£649): A beautifully built British charger with a 10-year enclosure warranty, smart tariff support, and the option of tethered or untethered installation.
Does the GivEnergy's Battery-to-EV Feature Justify the Lower Price?
At £478, the GivEnergy is £171 cheaper than the Simpson & Partners. That's a meaningful gap. But the value equation flips depending on one question: do you have a home battery?
If you do — especially a GivEnergy battery — this charger becomes a genuinely smart buy. Battery-to-EV charging means you can store cheap overnight electricity or excess solar during the day, then push it into your Tesla in the evening. You're effectively decoupling your charging from the grid at peak times. Pair it with the GivEnergy monitoring portal and you get whole-home energy management that no other charger at this price can touch. For solar and battery owners, our best EV charger for solar guide covers this setup in more detail.
Strip away the battery integration, though, and the GivEnergy is a fairly basic 7kW tethered charger with a 5-metre cable, limited smart tariff support, and an app that trails behind the competition. At £478 it's not bad — but it's not exciting either.
Is the Simpson & Partners Home 7's 10-Year Warranty Worth £171 More?
That warranty number grabs attention, and it should. Ten years on the enclosure is extraordinary — most chargers top out at three to five years. The anodised aluminium construction and UK manufacturing back it up; this isn't a plastic box bolted to your wall.
A caveat: the 10-year coverage applies to the enclosure, not necessarily every internal component. Still, aluminium doesn't crack, fade, or warp the way some polymer housings can after a few British winters. If you're planning to stay in your home for the long haul, that durability matters — both practically and for resale value.
The Simpson & Partners also offers something the GivEnergy doesn't: choice. You can get it tethered or untethered, in multiple finishes including Accoya wood. If you care about how a charger looks on the front of your house — and plenty of people do — this is one of the best-looking units under £700. It undercuts the Andersen A3 by over £300 while offering a warranty that's three years longer.
Smart Tariff Support: A Clear Winner
This is where the Simpson & Partners pulls decisively ahead for most buyers. It supports Octopus Go, OVO Anytime, and EDF GoElectric through its app, letting you schedule charging around cheap overnight rates. The GivEnergy's smart tariff integration is limited by comparison — it relies more on its battery ecosystem for cost savings than on direct tariff optimisation.
If you don't have a home battery and you're on a smart EV tariff, the Simpson & Partners will save you more money week to week. It's not as slick as an Ohme for tariff juggling, but it covers the major providers that matter.
For those chasing the absolute smartest tariff integration, our best smart EV charger guide breaks down the top options.
Which Should You Buy?
Buy the GivEnergy EV Charger if:
- You already own a home battery (GivEnergy or otherwise)
- You want battery-to-EV charging and whole-home energy monitoring
- You're building a solar-plus-storage setup and want everything under one ecosystem
- Budget matters and you don't need fancy app features
Buy the Simpson & Partners Home 7 if:
- You want the longest warranty available on a UK home charger
- You're on a smart tariff and want automated off-peak charging
- You prefer a premium, British-made unit with finish options
- You want the flexibility of tethered or untethered installation
For most Tesla owners without a home battery, the Simpson & Partners Home 7 is the better buy. Yes, it costs £171 more — but you get smart tariff support, a far longer warranty, and hardware that's built to outlast the car. The GivEnergy only makes sense as part of a wider energy storage strategy. If that's your world, it's brilliant. If it's not, look elsewhere. Our best Tesla home charger guide covers the full field.
