My Car Keeps Charging Beyond the Limit Set in the Octopus App
If your car is charging beyond the limit set in the Octopus app, it’s because the charge limit is not controlled by the app or the Simpson & Partners charger — it must be managed by your vehicle directly. Why This Happens • The Octopus Intelligent tariff controls when your car charges, not how much it charges. • The Simpson & Partners charger delivers energy during allowed charging times but cannot stop charging at a certain battery percentage. • Only your vehicle can limit the charge level. Neither the Octopus app nor the charger can override this.

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.

Why Choose Holiday Series EV Chargers over other Ev chargers?
Most holiday let chargers are cheap plastic units that look awful and break down. Holiday Series chargers are British-engineered from metal for superior durability and come in 132 colour combinations to match your property. We've been offering Business and Home EV chargers for years and started out making EV chargers in 2018. Crucially, they include OFGEM-compliant MID meters as standard. If you're charging guests for electricity, MID meters are a legal requirement in the UK. They're certified meters that provide accurate, auditable readings of exactly how much energy each guest uses protecting you from disputes and ensuring you charge fairly and legally. Purpose-built for holiday lets, Holiday Series chargers are reliable, beautiful, easy for guests to use and designed to generate revenue with minimal hassle.

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. Guests driving EV's need to charge it's an essential feature, not an extra. An on-site charger also generates better reviews and repeat bookings because it enhances the guest experience and shows you've thought of everything.

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."

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.

Can I use my own installer?
Yes. Any qualified electrician can install Simpson & Partners products. If you have your own trusted electrician it's a good idea to share installer guides with them ahead of time.

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.

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!"

Will Octopus still work if connected via my charge point?
Yes — connection via our charger is fully supported and will work as expected. Octopus can still start and stop charging, but it cannot automatically stop at your set battery limit because it doesn’t read the real-time charge level.

How does S&P pricing compare to other chargers with similar features?
Our wall‑mounted untethered chargers start from £649 inc. VAT. We keep pricing transparent and straightforward. Our premium build quality and smart features come as standard, and you only pay for optional upgrades like signature colours, metal lids or wireless energy management. Cheaper alternatives often cut corners or add hidden costs later. Every S&P charger includes a 10‑year external enclosure warranty and a 5‑year electrical warranty. Because we manufacture and finish our chargers in‑house and sell directly, you get exceptional quality at a genuinely competitive price.

Can I arrange my own installer and will this affect the Warranty?
Absolutely! You're welcome to use your own qualified electrician to install your Simpson & Partners Home Series charger. We recommend sharing our installer guides with your electrician beforehand – they'll find our chargers straightforward to install Good news about your warranty: Using your own installer won't affect your warranty at all, as long as the installation is completed by a qualified professional.

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.

Are your chargers easy to install?
Our EV chargers are designed to be installer-friendly, making the installation process straightforward for qualified electricians. Professional Installation Required: We recommend using a qualified electrician to install your charger. This isn't a DIY product – professional installation ensures your charger meets all safety standards and building regulations. Why installers love our chargers: Our products are built with installers in mind, featuring intuitive design and clear instructions that make the job quick and hassle-free. Easy setup for you: Once installed, connecting your charger to WiFi is simple. Just use Bluetooth on your mobile phone, stand near your charger, and follow the app prompts to connect to your WiFi network. You'll be up and running in minutes with full access to smart features like remote monitoring and charging schedules.

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.

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.

What’s the difference between home and business chargers?
Home chargers are perfect for residential use (7kw and 22kW and wall mount and freestanding options) with free mobile app and tethered or untethered options. Business chargers include all this and extra features like RFID authentication, MID metering and built-in RCBOs.

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.

Will I need to make any electrical upgrades to my property?
It depends on your existing setup. A qualified installer will assess your consumer unit and electrical capacity during the survey. If upgrades are needed (such as a new consumer unit to meet safety regulations) costs are typically around £85 and can be included in your installation quote. Emma from Beaumont House recommends: "Check your electrics first. We have 3-phase, meaning we could install as many chargers as we wanted within our budget. We opted for two 22kW chargers initially but made the underground pipework suitable for further cables as I hope to install more in the future."
Plus iconPlus icon
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.

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.
Plus iconPlus icon
Are S&P chargers more compatible with renewable energy than other brands?
Yes. Our chargers are fully solar-compatible, letting you maximise your home energy and reduce costs. Many other chargers claim “green energy support,” but only S&P chargers integrate seamlessly with solar generation and smart tariffs, making your EV charging both efficient and environmentally friendly.
Plus iconPlus icon
What if I don’t have a wall to mount the charger?
No problem! We offer freestanding posts with a single socket, allowing you to install a charger anywhere in your driveway or garage. These posts feature a fully integrated, discreet, and slim design. No wall? No problem!
