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."

Will having an EV charger help me get more bookings?
Yes. EV drivers actively filter their search for properties with on-site charging, and this segment is growing rapidly. Without a charger, you're invisible to these guests. Properties with charging see increased bookings year-round, improved competitiveness, and future-proof appeal as EV ownership continues to rise. Emma from Beaumont House Hotel in Cheltenham explains: "It makes the hotel appear higher up in the ranking on online travel agents such as Booking.com and Expedia as guests can tick hotels with EV chargers, we pop up immediately. I estimate 10% of business is repeat business by guests owning electric cars throughout the year." Simon from Coillemore House in the Scottish Highlands adds: "We were keen to offer EV charging as a value add and as a differentiator to other homes in the area. We were surprised to have multiple guests from the south east and London driving up in electric vehicles. There's more demand than we initially believed."

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. Upgrade to V3 Hardware If you have a V1 charger: • A hardware upgrade programme will be available soon • This will allow you to upgrade to the latest V3 hardware • Full details will be shared when the programme launches 3.

If you're not sure what version charger you have or need help upgrading: Contact the Simpson & Partners support team via simpson-partners.com/support Summary If your charger shows an upgrade message in the Octopus app, check your firmware version. • V1 chargers are not compatible and will require a hardware upgrade. • V2 and V3 chargers must be online and updated to work with Octopus Intelligent.

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."

Will the colour fade if my charger is outdoors?
No. Our paint finishes are designed to withstand UK weather, rain, UV sun and frost. Metal and wood lids on all models are treated for durability, so your charger will stay looking great for years. We make our wood lids our of sustainable Accoya. Dimensionally stable, Accoya wood is a modified pine that undergoes an acetylation process. The result is real wood that doesn’t rot. It doesn’t warp, swell or shrink becuase the small water molecules inside the wood are effectively replaced by acetic acid. ie it's 'pickled'. Wooden lids will in say 10 years begin to change colour if they are exposed to UV light. The change will be very slight becuase we use specialist transluscent paint coats that protect from UV light. The metal fronts are power coated. Their colour will stay the same for many years.
