EV Charging for Holiday Let Guests: Solar-Powered Setup

Quick answer

Adding a guest EV charger to a holiday let is one of the strongest cases for on-site solar. Daytime charging absorbs solar generation at near-100% self-consumption, and a battery lets guests charge from stored solar in the evening without straining your supply. A charge point is also a genuine listing selling point that EV-driving guests actively filter for. Small parks and multi-lodge sites may fund the sockets through the OZEV Workplace Charging Scheme.

Key takeaway: guest EV charging is not just a guest amenity, it is the load that makes your solar array work harder. A car plugged in on a bright day is a near-perfect match for what your roof is generating, and a charge point in your listing wins bookings you would otherwise lose to a competitor down the lane.

Why EV charging and solar belong together

The self-consumption match is the reason. Solar generation peaks in the middle of the day. A guest who arrives, settles in, and plugs in an electric car soaks up that generation almost exactly as it is produced. There is no cheaper electricity than the kilowatt-hour you generate and use on the spot rather than exporting it and re-buying at peak.

On a holiday let this is doubly true, because your occupancy peaks in the same sunny months. A charger sitting idle on a home during working hours is, on a let, busy through the summer when the array is generating most.

Stat callout: A 7 kW home-style charger drawing from a solar array on a bright day self-consumes generation at close to 100%, against a typical unbatteried self-consumption of only 30 to 50% for a daytime-empty home (Source: Energy Saving Trust, energysavingtrust.org.uk). Guest charging is one of the best loads a holiday let can add.

Add a battery and evening or overnight charging, when guests return from a day out and plug in, runs from stored midday sun rather than peak-rate grid electricity. We cover that pairing in our battery versus no battery guide.

The booking-appeal angle

EV drivers plan around charging. On the major booking platforms and on Google, a listing that offers on-site charging is filtered for and chosen over one that does not. As the UK EV fleet grows, “no charger” increasingly means a lost booking rather than a neutral one. Several owners now put their charge point and their solar low running costs directly in the listing to justify a premium nightly rate.

Pair the charger with an on-site solar array and you have an auditable, genuinely green amenity, which also feeds a Green Tourism award and the direct-booking advantage that brings.

Stat callout: The UK’s transition to electric vehicles is accelerating under the phase-out of new petrol and diesel car sales, which raises the share of guests arriving by EV year on year (Source: gov.uk, transitioning to zero emission cars and vans). For a holiday let, a charge point is moving from a bonus toward an expectation.

What to fit

A single cottage or lodge usually wants one 7 kW charge point on the drive, ideally a model that can be set to draw from solar or battery first. For a multi-lodge site or small park, plan several sockets and, importantly, a load-management setup so simultaneous charging does not trip your supply.

Key design points:

• Solar-first charging. Choose a charger that prioritises surplus solar and battery over grid import, so guests charge on your generation, not your bill. Most modern smart chargers offer an eco or solar-match mode that throttles charging to available surplus.
• Supply headroom. A 7 kW charger is a significant load. Rural and coastal lets are often on capacity-constrained networks, so we check the supply and, where a battery-plus-EV system is involved, submit a G99 application to the DNO rather than a simple G98 notification.
• Load management on multi-unit sites. Where several guests may charge at once, a load-balancing controller shares the available capacity across sockets so the site supply is never overloaded, which avoids an expensive supply upgrade.
• Guest metering. Some owners meter guest charging as a chargeable extra; others include it in the rate as a differentiator. Both work, decide before you fit.

Pricing models: include it or charge for it

There are two sensible ways to handle the cost of guest charging, and both are defensible.

Include it in the nightly rate. Positioning “free EV charging” as an amenity can justify a higher rate and wins the booking outright, particularly for premium lodges where the guest is already paying for extras. Because much of the charging draws on your own solar, the marginal cost to you in season is low.

Meter and charge for it. A metered smart charger lets you bill guests per kWh, which suits higher-turnover sites or where a single guest might charge a large battery repeatedly. This keeps the amenity available without absorbing an open-ended cost.

The right choice depends on your guest profile and your tariff. Either way, the solar underneath makes the economics work in your favour.

How the install works and what it involves

Fitting guest charging on a holiday let is a contained job, but a few sector-specific points are worth knowing before you book it.

First comes a supply check. A 7 kW charger draws a meaningful load, so the existing incoming supply and consumer unit are assessed to confirm they can carry it alongside the hot tub, hot water and any solar-and-battery system. On a constrained rural or coastal network this check is done early, because it can shape the design. Where a charger is fitted alongside a battery, the whole package is usually notified to the DNO under a G99 application rather than the simpler G98 route.

Physical installation of a single charge point is typically a one-day job: mounting the unit, running the cable back to the board, and commissioning the smart features and solar-match mode. On a multi-lodge site the added work is the load-balancing controller and the cabling to each socket, which is best scheduled in the quiet season. As with any electrical work on a let, we book the brief final connection outage for a changeover gap so no guest stay is disrupted. The charger is then linked to its app so you, and where relevant your guests, can control and monitor charging.

Funding: the OZEV Workplace Charging Scheme

For a business installing chargepoints, the Workplace Charging Scheme can cover up to 75% of cost, capped at £500 per socket (raised from £350 on 1 April 2026), up to 40 sockets. It must use an OZEV-approved installer and chargepoints. This is more relevant to a small park or multi-lodge site than a single cottage, and it pairs naturally with on-site solar. Eligibility for a holiday-let business is not automatic, so confirm your position.

On tax, the Furnished Holiday Lettings regime was abolished in April 2025, so the old capital-allowance route for personally-held lets has gone, take your own tax advice and see our grants and funding page.

How it varies by property type

• A self-catering cottage typically fits one 7 kW point, solar-first.
• A lodge or cabin increasingly treats charging as standard, so a battery to cover evening charging matters.
• A glamping site may run charging from an off-grid solar-and-battery system, see our off-grid glamping guide.
• A self-catering park is where the Workplace Charging Scheme and load management really come into play, with multiple sockets fed by a site-wide array.

Frequently asked questions

Can guests charge their EVs from my solar?

Yes, and it is one of the strongest cases for holiday-let solar. Daytime charging absorbs generation at near-100% self-consumption, and a battery lets guests charge from stored solar in the evening. A solar-match charger prioritises your generation over grid import automatically.

Do I need a special charger to use solar?

You need a smart charger with an eco or solar-match mode, which throttles the charge to available surplus. Most current models offer this. It is worth specifying at install rather than fitting a basic charger and upgrading later.

Will guest charging overload my supply?

A single 7 kW charger is manageable on most supplies, but rural and coastal lets are sometimes on constrained networks, so we check first. On multi-unit sites a load-balancing controller shares capacity across sockets so the supply is never exceeded.

Should I charge guests for charging or include it?

Both work. Including it as “free EV charging” wins bookings and justifies a higher rate, and in season much of it is your own solar. Metering suits higher-turnover sites. Decide before you fit, because it affects the charger model you choose.

How long does it take to install a guest charger?

A single 7 kW point is typically a one-day job after the supply check. A multi-lodge site takes longer because of the load-balancing controller and cabling to each socket, and that work is best scheduled in your quiet season.

We fit guest EV charging on holiday lets across the UK, including popular coastal bases like Salcombe and St Ives.

The verdict

Guest EV charging is a rare win-win on a holiday let: it makes your solar array work harder through near-perfect daytime self-consumption, and it wins bookings you would otherwise lose. Fit a solar-first 7 kW charger, add a battery to cover evening charging, and, on a park, look at the Workplace Charging Scheme to fund the sockets.
