A Cheaper Smart Charger vs a Premium Long-Laster
Here's an unusual comparison. The Ohme Home Pro costs less, does more with your energy tariff, and is one of the most popular chargers in the UK. The Simpson & Partners Home 7 costs more, comes from a brand most people haven't heard of, and bets everything on build quality and longevity. Two very different philosophies — and the right pick depends entirely on what you value.
In a nutshell:
- Ohme Home Pro (£535): The smart tariff king. Automatically charges at the cheapest rates, with built-in 4G and solar diverting.
- Simpson & Partners Home 7 (£649): British-made, anodised aluminium, 10-year enclosure warranty, and three-phase capable.
Does the Ohme Home Pro's Smart Tariff Integration Justify the Hype?
Absolutely. This is the single biggest differentiator between these two chargers, and it's not close.
The Ohme connects directly to your energy provider — Octopus, OVO, EDF, and others — and automatically shifts your charging to the cheapest half-hour slots. Pair it with Octopus Intelligent Go and you're looking at around 7p/kWh for overnight charging, handled entirely without you lifting a finger. The Simpson & Partners Home 7 does support some smart tariffs, but it's a more basic implementation. You can schedule charging, but you won't get the granular, real-time price optimisation that the Ohme delivers on tariffs like Octopus Agile.
If you're on a smart tariff — or willing to switch to one — the Ohme will likely save you £200-400 a year compared to charging at standard rates. That wipes out the purchase price difference in a matter of months and keeps paying you back year after year.

Is the Simpson & Partners 10-Year Warranty Worth £114 More?
That headline warranty figure demands a closer look. The 10-year coverage applies to the enclosure — the anodised aluminium housing — not necessarily every internal component. It's still remarkable. No other home charger on the UK market comes close to that duration, and the build quality backs it up. This is a heavy, solid unit made from materials designed to weather decades of British rain.
But here's the thing: the Ohme Home Pro's 3-year warranty is standard for the industry, and most charger failures happen within the first couple of years anyway. The Simpson & Partners warranty is reassuring if you plan to stay in your home long-term and want something that looks good on your wall for a decade-plus. If you're the type who replaces tech every few years, it matters less.
Where the Home 7 does offer a genuine technical edge is three-phase support. At 22kW on a three-phase supply, it charges roughly three times faster than the Ohme's 7.4kW maximum. If your property has three-phase power — or you're planning an upgrade — the Simpson & Partners is one of the cheapest ways to access that speed. The Ohme simply can't compete here.
Design and Day-to-Day Living With Each Charger
The Ohme Home Pro is compact and light at 3.5 kg, with a colour display on the front that shows charging status without needing your phone. It also packs built-in 4G with a three-year SIM included, so it stays connected even if your home Wi-Fi doesn't reach the driveway. That's a thoughtful touch that most competitors miss.
The Simpson & Partners Home 7 takes a different approach. It's larger and heavier at 5.5 kg, but it looks and feels like a premium product. Multiple finish options — including Accoya wood — mean you can match it to your home's exterior. It's available in both tethered and untethered versions, which gives you flexibility the Ohme doesn't offer (the Ohme is tethered only). The app, however, is functional rather than polished. If you're used to slick interfaces from Tesla or Ohme, expect a step down.
One practical note: both chargers come with 5-metre cables in their tethered versions. If you need more reach, the Ohme offers an 8-metre option at extra cost. The Simpson & Partners doesn't advertise a longer cable variant. If your parking spot is far from your consumer unit, check the cable length carefully — our best Tesla home charger guide covers this in more detail.
Which Should You Buy?
Buy the Ohme Home Pro if:
- You're on a smart energy tariff or willing to switch to one
- Minimising your electricity costs is the top priority
- You want built-in 4G backup connectivity
- You have solar panels and want built-in solar diverting
Buy the Simpson & Partners Home 7 if:
- You want a charger that'll last a decade or more with a warranty to match
- Your home has three-phase power and you want 22kW charging
- Aesthetics matter — you want premium materials and finish options
- You prefer an untethered socket for a cleaner wall-mounted look
For most Tesla owners on a single-phase supply, the Ohme Home Pro is the smarter purchase. It costs less upfront, saves more on running costs, and its smart tariff integration is best-in-class. The Simpson & Partners Home 7 is a beautiful, well-built charger that deserves more attention than it gets — but unless you need three-phase or prioritise longevity above all else, the Ohme's daily savings are hard to argue with.
