What’s the difference between Tethered and Untethered chargers?
Tethered: The charger comes with a cable permanently attached, so it's quick and easy to plug in and go. This is ideal if you always use the same vehicle and want maximum convenience. Untethered: The charger has no fixed cable — you use your own instead. This gives you a neater look with no cable on show when not in use. You can also leave your cable plugged into the charger between charges if you prefer, giving you the best of both worlds.

Do the colours affect durability or performance?
Not at all. All our lids and finishes meet our high-quality standards. The choice of metal, wood or plastic is purely aesthetic, your charger will perform reliably whatever colour you pick. Our metal fronts are powder coated. Our lids are either anodised or made of sustainable Accoya wood with a no-rot guarantee for 50 years.

Can your chargers meet unique or complex installation needs?
Yes. Our Business Series modular system is built for complex installations — from tight urban developments to large private car parks. Unlike all-in-one bundles where you pay for features you don't need, our system lets you configure exactly what you require: MID meters, daisy chaining, plinth-only installations, and OCPP compatibility for buildings with solar and battery storage.

Is the cable hidden or wrapped around a holder?
Our tethered EV charging cables can be neatly wrapped around the charging unit itself, keeping your driveway or garage tidy.For added convenience, we also offer a colour-matched cable hook (£49) as an optional extra at checkout. This provides a nice way to keep your cable tidy and it's by default colour matched to the chargers front.

What’s the difference between the Home 7 and Home 22?
The Home 7 and Home 7 Plus are both single-phase AC chargers and will deliver up to 7.3kW (32 amps) to your car. The Home 22 is a three-phase charger and can deliver up to 22kW—three times the power. Just keep in mind, you’ll need a three-phase power supply to get the full 22kW.

Why is standard installation from £425 excluding vat?
Every installation is different and every installation cost varies. We've been in the charging industry for years and there are too many variables to stick to a one price fits all. Having said that, we have given a 'from' price for standard installation for transparency and to give our customers a rough indication of what to expect to pay for. We believe this is a very fair cost. All Trusted Partners are local independent electricians that we have known for years, selected for their commitment to great workmanship and high levels of customer service.

If Octopus controls charging, will it always be off-peak?
Not necessarily. Octopus may charge your car at any time to optimise cost and carbon efficiency. Your bill will still reflect the lower smart charging rate.
Plus iconPlus icon
Do the chargers work in extreme weather?
Yes. All chargers (freestanding and wall mounted) are IP-rated, weatherproof and designed for outdoor use in rain, snow, or extreme temperatures.
Plus iconPlus icon
Do your chargers work with all EV models?
Yes! Our EV chargers are compatible with all EV brands, including those from VW Group, Tesla, BMW, Nissan and more. Charge point connections are fully supported and work as expected with all EVs.

What is the difference between single-phase and three-phase power?
Single-phase power is the standard electricity supply for most UK homes — around 85% of domestic properties use it. It delivers electricity through one live wire and is protected by a single fuse (typically rated at 60, 80, or 100 amps). With single-phase, the maximum charging rate for an EV charger is usually 7.3kW, which is ideal for overnight charging and suits most households. Three-phase power, on the other hand, is more common in commercial buildings or larger homes. It uses three live wires, allowing electricity to flow more efficiently and at higher capacity. If your property has a three-phase supply, you can install a charger capable of delivering up to 22kW —useful for larger battery EVs or homes with multiple electric vehicles needing faster turnaround. In short: • Single-phase = up to 7.3kW charging, standard for most homes • Three-phase = up to 22kW charging, suited for high-demand setups, commercial car parks, multi-dwelling residences.

Should I Upgrade to 3-phase power supply?
It's up to you, but upgrading to 3-phase isn't common for most homes. When 3-phase makes sense: You have two EVs that could share the charging load You're already planning to install high-demand appliances like heat pumps, hot tubs, or indoor swimming pools You want the fastest possible home charging (up to 22kW) Who typically has 3-phase power? Most commercial premises like warehouses, farms, factories, shops, and restaurants have 3-phase. Some residential properties do too – particularly new-build large homes, barn conversions, or apartments in tower blocks with lifts. The reality: Upgrading to 3-phase can be time-consuming and expensive. For most homeowners with a single EV, standard single-phase power and a 7kW charger provides perfectly adequate overnight charging. How do I explore the option? Contact your district network operator or the national grid .national grid.

Can you help me compare different brands of electric vehicle chargers for my business?
Yes — when comparing EV charger brands for business use, consider features like user management, metering, access control, installation flexibility and future‑proofing. For example, the Simpson & Partners Home Series EV Charger Plus and its business counterpart from Simpson & Partners offer commercial‑grade options: MID‑certified metering, RFID access control and OCPP support for workplaces and visitor parking. When comparing other brands, check whether they also provide features such as built‑in RCBOs, dynamic load management and freestanding posts. Simpson & Partners stands out for blending these business features with aesthetic design and UK manufacturing.

What is a Wired Energy Manager?
The Wired Energy Manager is a clever small device that balances the electrical load between your car and home. It constantly measures the amount of energy that your home is using and sends any availiable energy to your car (if it's plugged in). Known as a 'load balancing' device it avoids nuisance trips by prioritising energy to the home. So for example when you use the hob, hot tub, microwave etc, the energy manager will prioritise energy for your home appliances and reduce energy going to your car. As soon as you switch off your home appliances and 'reduce the load' on the house, it sends more to your car. We include a Wired Energy Manager with every Home basic or Home Plus charger.

What is Three-Phase Supply?
Three-phase power is term used for describing the amount of power going into a building from the national grid. It is more commonly found in commercial buildings or larger homes. It uses three live wires, allowing electricity to be delivered more efficiently and at a higher capacity than the more common single-phase power. If your property has a three-phase supply, this means that it supports up to 22kW charging. So if you install a 22kW charger, you’ll be able to send up to 22kW to your vehicle. Which can be useful for vehicles with larger on-board battery or busy households with 2 or more EVs. If your home has single phase power, then you'll be able to happily charge up to 7kw.

All Simpson & Partners EV chargers come with powerful management software built-in, designed for both home and commercial use.For home use – Our Home Series chargers seamlessly integrate with intelligent octopus go, the plus models allow you to use excess solar energy and the app allows you to lock your charger, set charging schedules and track energy usage.
