Are Simpson & Partners chargers suitable for listed or historic buildings?
Homeowners that live in listed buildings (grade 1 or 2) or in conservation areas often chose our chargers due to their elegant design, discreet installation finish and customisable finishes. We are happy to help put together plans and image packs to present to your relevant authorities or heritage organisation panels to win their permission and gain approval. Our wall mount chargers are very small and slim. They come in metal (not plastic) with an option for wood lids and a carefully curated colour selection. Our integrated freestanding posts are also very discreet and help the charger blend seamlessly into environments where the final appearance is important.

What features should I look for in an electric vehicle charger for commercial use?
Choosing the right EV charging solution for your hotel, business, or facility means finding a system that serves your guests, staff, and visitors reliably while fitting your operational needs and budget. Simpson Partners' Commercial Series delivers elegant, commercial-grade AC charging designed specifically for hospitality venues, workplaces, apartment blocks, and visitor car parks. We work with you and qualified electrical engineers to tailor a charging solution that meets your requirements on time and on budget. Key Features to Consider: Charging Speed – 7–22 kW AC charging suits guests and staff who park for extended periods, ensuring vehicles are ready when needed. Flexible & Scalable – We offer dual socket pedestals, single socket wall mount models, and plinth-only models to suit your site layout and budget. Start with what you need today and expand easily as EV adoption grows among your guests and team. Our plinth-only option is a clever way to future-proof your charging: install the plinth infrastructure now alongside your active chargers, then add sockets later when budget allows. This cost-effective approach gets the groundworks done once, saving you money and disruption down the line. Easy Management – Our commercial chargers are OCPP-compliant, allowing seamless control through third-party specialist energy apps such as Fuuse, Tap, and Wevo. This means seamless integration if your site already has solar PV, battery storage, and daytime charging. Tap, for example, is a free app for landlords and businesses that cleverly bills users when they charge their car, with payments going straight into your bank account. Built to Last – Robust, weather-resistant designs withstand heavy use in outdoor and high-traffic environments. Future-Proof Compatibility – Universal connectors and open standards ensure your investment works with all vehicle types and avoids vendor lock-in.

What’s the difference between wall-mounted and free-standing chargers?
Wall-mounted chargers attach to a suitable vertical wall (eg brick). The free-standing charger is an integrated pedestal model that has been designed for properties and driveways and car parking bays that don’t have a wall nearby to mount the charger on.

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.‍

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 do guests know how to use the charger?
It's simple. Provide clear instructions in your guestbook under "Practical Essentials" alongside check-in times and Wi-Fi details. If using Tap Electric, guests scan the unique QR code on the charger to start charging and pay automatically. A well-lit setup and basic signage make self-charging straightforward for all guests. At Nuthatch Retreat: "Guests are always happy to know that all they need to do is bring their cable and plug in after a day exploring the area. No need to download apps or add credit to accounts."

What’s the difference between a Wired vs Wireless Energy Manager?
A Wired Energy Manager is a hard-wired kit that monitors your home’s power draw, so your charger knows when to throttle EV charging to avoid overloading your main supply. A wireless Energy Manager gives you the same load-balancing benefits, but communicates over wireless — handy if you want cleaner install and simpler cabling. Both options protect your home electrical system while optimising charging.
Plus iconPlus icon
Will it actually increase my bookings?
Yes. EV drivers actively filter their search for properties with on-site charging. Without it, you're invisible to this fast-growing market. As EV ownership increases, properties without charging are losing bookings year-round to those that offer it. An on-site charger also generates better reviews and repeat bookings because it enhances the guest experience, gives EV drivers a home from home necessity. Even for those that don't have an ev, well, it shows you've thought of everything.

How fast can I charge my car?
The speed you can charge your car at home depends on three things: your home’s electricity supply, the charger you install (7kW or 22kW) and your car’s onboard charging capability. Most UK homes have a single-phase supply, which supports up to 7kW charging. If you have a three-phase supply, you can install a 22kW charger for much faster charging. The third but crucial element is your car’s onboard battery. Sometimes referred to as an OBC, the onboard battery is fixed and inside your car. Some hybrid plug in cars have 3.7kW on board battery, the majority of cars have 7kW, some have 11kW and a few have 22kW. The fastest you can charge your car at home is always going to be limited by the smallest number: Let’s see this in action: Example 1: If your home power supply is single phase and you choose a 7kW charger and plug in a Tesla with an onboard battery of 22kw, then the fastest you can charge will be 7kW. This is because the maximum available of power at your home is 7kW. If you have a 22kW charger, then the maximum rate you can charge is still 7kW. Example 2: You have three phase power supply and a 22kW eV charger, your car is a lovely brand-new car that has an on-board charger of 3.7kW. The fastest you’d be able to charge is 3.7kW.

What is load balancing?
Load balancing is a safety feature which automatically balances the power consumption between your house and the charger, to avoid overloading your fuse. For example, if your home has a 60A fuse and you turn on the electric ovens, electric showers and other high draw appliances and try and charge your vehicle same time, there may not be enough load available for the charger to charge at the maximum rate (which is 32A). When this happens, the charger automatically lowers the charge rate to avoid overloading your supply. To enable load balancing, connect the wired Energy Manager included with Home Series products, or purchase the optional wireless Energy Manager.

Is installing an EV charger a good long-term investment?
Absolutely. EV chargers are considered fixed appliances that increase your property's value and future-proof it for the growing EV market. Our data shows a single-socket charger pays for itself in approximately 12 months through guest charging revenue. After that, it's a permanent income stream with minimal ongoing effort required from you. Simon from Coillemore House addresses remote locations: "The nearest public charging station is about 40 minutes drive away, so it's not really practical for guests to use. It adds time to their day trips. It's much preferable for them to be able to plug in whilst back at the house relaxing in the hot tub or preparing dinner. Before we had the charger, guests with EVs just had to plug into a socket through a window. It wasn't ideal as we couldn't charge them easily and couldn't offer fast or efficient charging." Emma from Beaumont House adds: "Guests often think charging points are more essential than a breakfast service. If you need to charge, you need to charge!"

How do I choose the best electric vehicle charging solution for my needs?
Choosing the right EV charging solution depends on your property, vehicles, and how you'll use it. At Simpson & Partners, we've built a product solution designed to hit all the things that matter – our chargers are beautiful, durable, repairable and upgradable, so they won't end up in landfill. Here's what to consider: Charging speed – 7 kW works well for standard overnight home charging and runs on single-phase power available in most homes. 22 kW is better for faster top-ups and larger batteries, but requires a three-phase power supply, which typically isn't widely available in domestic properties. Charger type – Tethered chargers offer convenience with an attached cable, untethered gives you flexibility to use your own cable, or choose a freestanding unit if you don't have a suitable wall. Smart features – Our chargers connect with Intelligent Octopus and offer app monitoring, energy management, and integration with smart tariffs to help reduce costs. Installation location – Wall-mounted chargers suit most homes, while freestanding units work well for driveways and commercial sites. Home vs business use – We offer a dedicated commercial range built for heavy-duty business environments and high-demand use, featuring RFID access control, MID metering for accurate billing, and built-in RCBOs for safety. For home charging, we provide industry-leading warranties: 10 years on the enclosure and 5 years on the electronics, giving you complete peace of mind. Future-proofing – Our chargers can be upgraded for emerging technologies like V2G (vehicle-to-grid), and because they're repairable, they're built to last for years to come. Design and aesthetics – Choose colours and finishes that complement your property, with options suitable for heritage or listed buildings.

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.

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.
