## Quick Verdict
**The Simpson & Partners Home Series V3 is the most beautifully made home EV charger in the UK.** If you care deeply about design, build quality, and matching your charger to your home's aesthetic, nothing else comes close. The 10-year warranty is genuinely industry-leading, and the addition of Intelligent Octopus Go integration makes it a much stronger smart charger than previous versions. However, the app needs work, 4G connectivity costs extra, and the overall price climbs quickly once you start adding premium options.
**Pros:**
- Exquisite build quality — anodised aluminium, not plastic
- Up to 132 colour combinations with metal and wood lid options
- 10-year enclosure warranty — the longest in the market
- Intelligent Octopus Go and OVO Charge Anytime compatible
- Solar compatible on Plus models
- Compact A4-sized footprint — discreet on any wall
- Cable lock feature on untethered models for tethered-style convenience
- UK-designed and manufactured in the Cotswolds
- 22kW three-phase option available
**Cons:**
- App has received significant criticism (screen sizing issues, connectivity glitches)
- 4G connectivity is an optional extra — not included as standard
- No display screen on the charger
- Price climbs quickly with premium options (Plus, colour upgrades, cable)
- Smaller brand with less established installer network than Ohme or myenergi

## Design and Build — Where Simpson & Partners Excels
Let's start with what makes Simpson & Partners genuinely special: the craftsmanship. This is not a plastic box on your wall. The Home Series V3 is built from anodised aluminium with a choice of metal or accoya wood lids, giving it a tactile premium quality that no other home charger matches.
At just 286 × 196 × 111mm — roughly the size of an A4 sheet of paper — it's remarkably compact and discreet. Where the [Hypervolt Home 3 Pro](/reviews/hypervolt-home-3-review/) makes a bold design statement with LED light rings, the Simpson & Partners takes the opposite approach: quiet luxury. It's the EV charger equivalent of a well-tailored suit rather than a flashy sports car.
The colour customisation is extraordinary. The Basic model offers four colour options, but step up to the Plus (from £759) and you unlock 13 metal front colours — from Neptune Blue to Dark Champagne to Kemble Green — each combinable with different metal or wood lids. That's up to 132 different colour combinations. You can match your charger to your front door, your garage, your car, or simply pick something beautiful.
The metal construction doesn't just look good — it's genuinely more durable than plastic. UV resistance is inherent to the material, so there's no yellowing over the years. The IP54 rating handles standard UK weather, though it's worth noting that the [Hypervolt Home 3 Pro](/reviews/hypervolt-home-3-review/) (IP66) and [Easee One](/reviews/easee-one-review/) (IP54 + IK10) offer better protection ratings.
## The 10-Year Warranty — Unmatched
This deserves its own section because it's genuinely remarkable. Simpson & Partners offers a **10-year enclosure warranty** on every Home Series charger. That's more than triple the industry standard of 3 years and longer than any competitor we're aware of.
For context:
- [Ohme Home Pro](/reviews/ohme-home-pro-review/): 3 years
- [Easee One](/reviews/easee-one-review/): 3 years
- [Hypervolt Home 3 Pro](/reviews/hypervolt-home-3-review/): 3 years (5 years for +£100)
- [myenergi Zappi](/reviews/zappi-v2-review/): 3 years
- **Simpson & Partners Home Series V3: 10 years**
That warranty speaks to confidence in build quality. Simpson & Partners' ethos is explicitly about creating chargers that "won't end up in landfill" — they're designed to be upgradeable and repairable rather than disposable. It's a refreshing approach in a market where three-year product cycles are the norm.
## Smart Features — Intelligent Octopus Go Integration
One of the most significant upgrades to the Home Series V3 is its compatibility with **Intelligent Octopus Go**. This was a missing feature on earlier Simpson & Partners models and its addition transforms the charger's value proposition.
With Intelligent Octopus Go, the charger communicates directly with Octopus Energy's system to schedule charging during the cheapest off-peak slots — typically 6–8p/kWh overnight. Set your departure time and desired charge level, and the system handles everything automatically. Simpson & Partners claims this integration can save owners more than £586 per year.
The charger is also compatible with **OVO Charge Anytime**, giving you a choice of smart tariffs that's broader than many competitors offer.
Beyond tariff integration, the charger supports:
- Manual charging schedules with day-by-day customisation
- Solar priority charging (Plus models with CT clamp/wireless energy manager)
- Stop/start control via the smartphone app
- Charging session analytics and cost tracking
## Solar Compatibility
The Simpson & Partners Home Series V3 Plus models come with solar charging capability. Using either a wired CT clamp or the optional wireless energy manager (for a cleaner installation), the charger can prioritise surplus solar energy when available.
It's not as granular as the [Hypervolt Home 3 Pro's](/reviews/hypervolt-home-3-review/) three-mode system or the [myenergi Zappi's](/reviews/zappi-v2-review/) dedicated Eco+ mode, but it handles the basics well: charge from solar when it's available, supplement from the grid when it's not. For most solar panel owners, this covers the core use case.
Note that solar is only available on the Plus model — the Basic doesn't include it. See our [solar panels and EV charging guide](/guides/ev-charger-solar-panels-uk/) for more on this topic.
## The App — The Weak Spot
This is where we need to be honest: the Simpson & Partners app is the charger's weakest link. While it covers the expected functionality — scheduling, start/stop control, session analytics — user reviews on Google Play have been notably critical.
Common complaints include:
- **Screen sizing issues** — the redesigned app doesn't fit correctly on certain smartphone screens, making buttons inaccessible
- **Connectivity problems** — some users report the app failing to connect to charge scheduling
- **General instability** — intermittent crashes and slow response times
These aren't universal issues — plenty of users report a perfectly fine experience — but they occur frequently enough to be a genuine concern. For a charger at this price point, the app should be polished and reliable.
Simpson & Partners is a small team, and they're actively working on app improvements. But compared to the slick, well-resourced apps from [Ohme](/reviews/ohme-home-pro-review/) or [Hypervolt](/reviews/hypervolt-home-3-review/), there's a gap that needs closing.
## Connectivity
The Home Series V3 connects via Wi-Fi, Bluetooth, and Ethernet. That Ethernet option is unusual in home chargers and provides the most stable connection possible — great if your charger is in a garage with a nearby network point.
However, there's a notable omission: **4G is not included as standard**. It's available as an optional extra at additional cost. This is disappointing given that the [Ohme Home Pro](/reviews/ohme-home-pro-review/) includes 4G as standard, and the [Easee One](/reviews/easee-one-review/) offers lifetime 4G with no subscription. For a premium charger, paying extra for mobile connectivity feels stingy.
## Installation
The Simpson & Partners offers both a tethered option (6.8m cable for +£50 on Basic, or 10m for +£100) and an untethered socket version. The untethered model includes a clever cable lock feature — you can lock a Type 2 cable in place to mimic a tethered setup, then unlock and remove it whenever you want.
Installation is handled through Simpson & Partners' network of over 700 qualified UK electricians. The charger includes PEN fault protection, so no earth rod is required.
The charger is **OZEV grant eligible**. The EV Chargepoint Grant covers up to £350 towards installation for eligible renters, flat owners, and landlords. See our [OZEV grant guide](/guides/ev-charger-government-grant-uk/) for details.
**Pricing:** The Basic model starts from approximately £649 (unit only), while the Plus starts from £759. With premium colour options, tethered cable, and installation, expect to pay £1,000–£1,300 all-in. After the OZEV grant (if eligible), roughly £650–£950.
## Charging Speed
The standard Home Series V3 delivers 7kW on a single-phase supply — slightly below the 7.4kW maximum that some competitors achieve at 32A. In practice, the difference is negligible: roughly 25–28 miles of range per hour, with most EVs charging fully in 6–10 hours overnight.
For homes with a three-phase electricity supply (uncommon in UK residential properties but available in some newer builds), Simpson & Partners offers a 22kW version — capable of charging an EV from 10–80% in 2–4 hours.
