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.

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.

How much does it cost to install an EV charger?
Standard installations start at £425 including VAT, with upfront costs typically offset within 12 months through guest usage. This covers a 7kW (single phase) installation, up to 4 hours on-site, and up to 15 meters of cable run. Costs increase if you need additional work such as drilling through multiple walls, trenching, working at height, or three-phase installations.

What type of EV charger is best for my holiday let?
Look for a reliable, durable charger with minimal downtime that complements your property's aesthetic. It should include MID meters for accurate billing and OFGEM compliance with UK government requirements. Simpson & Partners Holiday Series offers both wall-mounted and freestanding models, built from metal (not plastic) with 132 colour combinations to enhance your property. Simon from Coillemore House chose carefully: "I chose the Home 7 Plus so I could get the right colour combination. Neptune blue with a mid oak lid to fit in with the stone walls of our Georgian property. We love how it looks, it's super durable so it can stand up to all the weather Scotland can throw at it, and it's discreet so it doesn't look out of place."

How does the build quality of Simpson & Partners chargers compare to other brands?
We have an industry leading 10 year warranty on the enclosures. Our charger fronts are made of die-cast metal. We designed and chose metal for it's superior strength and durability. The vast majority of EV chargers on the market are made of plastic enclosures. This limits the shape, finish and colours. We then powder coat by hand to a very high finish. Compared to plastic ev chargers, our chargers are heavier and customers and installers often comment on how they can feel and see the build quality. Our charger lids are available in precision-CNC milled metal or sustainable Accoya real wood. With IP65-rated enclosures, premium materials, and rigorous testing, they’re built to withstand the UK’s toughest weather. Many other brands don’t match this level of durability, which means our chargers stay looking and performing like new for longer. ‍

Are your chargers compatible with all types of EVs?
Absolutely. Simpson & Partners chargers are engineered to support all EV models and PHEV. Tethered (Built-in Cable): Comes with a fixed Type 2 cable. Untethered (Socket): Features a universal socket, allowing you to use your own Type 1 or Type 2 charging cable, supporting older Type 1 vehicles as well as newer Type 2 cars.

Octopus Intelligent Says My Charger Requires an Upgrade
If you're seeing a message from Octopus Intelligent that your charger needs an upgrade, it's likely that your charger's hardware version isn't compatible with Octopus Intelligent. This guide explains why and what you can do about it. Why This Happens • Octopus Intelligent relies on a communication protocol called OCPP, which requires certain hardware capabilities. • Only V2 and V3 Simpson & Partners chargers support this protocol. • V1 chargers do not have the required memory or processing power to work with Octopus Intelligent. How to Check Your Charger’s Hardware Version 1. Open the Simpson & Partners app 2. Go to Settings 3. Tap on Info 4. Look at the Firmware Version Use the first number of the firmware version to identify your hardware type: • 1.x.x = V1 • 2.x.x = V2 • 3.x.x = V3 If your firmware version starts with 1, your charger is a V1 model and will need to be upgraded to work with Octopus Intelligent. What Are My Options? 1. Confirm Your Firmware is Up to Date If you have a V2 or V3 charger, but still see the upgrade message: • Make sure your charger is connected to the internet • Restart the charger to trigger a firmware update • During an update, the status light will flash purple 2.

What is the difference between the Home Basic and Home Plus?
The Basic comes with a plastic lid and the Home Plus has eco wood or metal lid options. The Plus comes with more front colours, options of wireless energy management and ethernet connection (rather than only wired energy management and wifi only), courtesy lights and the Charge Doctor. The Charge Doctor is a clever device that automatically detects faults and instantaneously fixes them without you even knowing about them.

Can I see the colours before I buy?
Absolutely. Order a free colour card so you can see the colours in your own space before committing. Order from our website and we’ll post it out via snail mail.

Can your charger work smarter with my energy and solar setup?
Yes! Our Home Series Plus chargers are designed to work seamlessly with solar panels, intelligently using any surplus energy your system produces. Every charger comes with a Wired Energy Manager as standard, and you can also choose a Wireless Energy Manager if that suits your setup better. Together, they automatically balance power between your home and your EV, helping you make the most of renewable energy, charge efficiently and keep your energy bills down.‍

How does guest payment work?
You have two options. Use Tap Electric (free for hosts) where guests scan a QR code on the charger, pay automatically, and the money goes straight to your bank account. Or check the Simpson & Partners app to see exactly how much energy was used and collect payment before guests leave. Either way, you set your own kWh rate and guests understand they need to pay, just like they would at any public charging point.
Plus iconPlus icon
Which of our chargers is right for your home?
The Home Series Basic models are perfect for straightforward home charging. Select from 4 colour options for the wall mounted model including a grey plastic lid and wired energy management as standard. The Home Series Plus models give you more choice more signature colours, metal or wood lids, solar integration and wireless energy management. Both Basic or Plus options have tethered or untethered options and come as 7kW or 22kW models so you can get a charger that fits your home, style and wallet. No wall? No problem! If you have a driveway without a nearby wall to mount a charger on, then consider our Freestanding model. We really like this as its discreet, fully integrated. It's even slimmer in real life and looks like quiet luxury.

Do I need a Wired Energy Manager?
A Wired Energy Manager is included with every charger. It is a CT clamp. We include one for a 7kW model and three for a 22kW model.

How do I charge guests for using the EV charger?
You set your own kWh rate and have two payment options. Use Tap Electric (free for hosts) where guests scan a QR code and pay automatically, with revenue going straight to your bank account. Or check the Simpson & Partners app to see energy usage and collect payment before guests leave. Either way, it's hassle-free. Beaumont House uses Tap Electric: "Tap Electric's app is so much simpler for guests to use. We haven't had one request for help with the app since installing Simpson & Partners chargers."

What information do I need to provide in the survey?
Installers typically ask for photos of where you want to put your charger (it could be in two places if you can't decide), a clear close up photo of your consumer unit with the lid open so they can see the switches and numbers on it), a photo of your fuse box (so they can see what power supply you have) and a rough distance in metres between the consumer unit and where you want to put your charger. Lastly they will want to know the model of charger - is it a wall mount 7kW or 22kW or a freestanding pedestal etc... A good electrician will help you decide whether you need wireless energy manager and provide advice on where best to install your charger.
Plus iconPlus icon
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.

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
What smart features set Simpson & Partners chargers apart from competitors?
Every S&P charger comes with smart app control, load management, and over-the-air updates. That means you can schedule charging, monitor usage, and future-proof your setup. Some competitors may have app control, but few combine this with advanced energy management and OTA updates in one reliable package.

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.

How Easy Is It to Upgrade to 3-Phase Power?
The short answer is it’s not that simple (or cheap) to upgrade your property to 3-phase power supply. But here are the steps on how to upgrade to 3-phase: You’ll need to reach out to your Distribution Network Operator (DNO). If you don’t know who your DNO is, contact your electricity provider or search “who is my DNO”. Your DNO are responsible for the infrastructure that supplies electricity to your home or business. Assessment: The DNO will assess whether a 3-phase upgrade is feasible for your property. The feasibility study outcome depends on your location, existing supply and how close you are to a 3-phase network. Costs can vary widely, from a few hundred to several thousand pounds. It really depends on the complexity of the work. How long does it take? It may take several weeks or months to complete, especially if roadworks or new cabling are required. You will bear the full cost of this work as there are no grants available.
