Lodge & Cabin Holiday Lets: Solar panels for holiday lets

A premium holiday lodge or cabin uses more electricity than a self-catering cottage, and that changes the solar case in the owner’s favour. The hot tub runs harder because guests expect it always ready, guest EV charging is close to standard rather than a novelty, and the eco-conscious guests who book high-end timber lodges respond strongly to visible renewables. A lodge is a heavier, more concentrated load than a cottage, packed into the same April-to-October season when a UK array generates most, which is exactly the profile solar and battery suit best.

A premium lodge or cabin typically suits a 5-10 kW roof array with a 5-13 kWh battery, around 12-25 panels across 30-65 square metres, at an indicative project value of £9,000-£20,000. That generates roughly 4,500-9,500 kWh a year and saves in the region of 1-2 tonnes of CO2. Indicative payback sits near eight and a half years, and it tends to come in at the faster end of the holiday-let range because a lodge’s hot-tub and EV load is higher and better matched to the sun than a lighter-used cottage. These are scoping ranges, not quotes.

Why a lodge is a heavier load than a cottage

The difference between a cottage and a premium lodge is intensity. A cottage hot tub might be brought up to temperature for each arrival; a lodge hot tub is often kept hot and ready throughout the letting period because a cold tub on a premium booking is a review risk the owner will not take. That means the 2-3 kW heater cycles harder and for more hours, much of it in daylight, which is generation a well-sized array can absorb directly.

Guest EV charging is the second intensifier. On a premium lodge a charge point is increasingly expected rather than a bonus, and EV-driving guests filter listings for it. Daytime charging is a near-perfect self-consumption match, drawing solar the moment it is generated, and a battery lets a guest charge from stored solar in the evening without straining the supply. Where an owner runs several lodges, guest charging across the site becomes a meaningful shared load that solar offsets across the whole letting operation.

Roof space is the constraint that pushes the design toward storage. A single lodge has a limited roof footprint, so you cannot simply add more panels to chase a bigger load. That makes the battery even more important on a lodge than on a cottage, because time-shifting a fixed daytime generation into the evening hot-tub and EV demand is how you extract full value from a roof that cannot grow. A 5-13 kWh battery sized to the lodge’s evening pattern is usually the difference between a decent return and a strong one.

Timber roofs, orientation and the fixed-footprint problem

A timber lodge or cabin brings its own design questions. The roof is often a single shallow or steep pitch on a compact footprint, sometimes with a veranda or dormer that eats into the usable area, and the structure is lighter than a masonry cottage. That means the mounting and load calculation are done properly for a timber deck rather than assumed from a tiled roof, and the panel count is sized to the real, often modest, area available. Because you cannot extend a lodge roof, the design leans harder on two levers: high-efficiency panels to get more generation from limited space, and a well-sized battery to make the most of every kilowatt-hour that roof produces. Where the lodge faces a view, and many premium lodges are sited precisely for one, the best roof slope for solar may be the rear or side pitch away from the aspect, which suits discreet siting in a sensitive landscape as well.

Multiple lodges under one owner

Many of our lodge enquiries come from owners running a handful of premium units on their own land rather than a single cabin. Where you control several lodges, a small site-wide array on a central building, a reception, a laundry or a plant room, can serve the shared load the whole operation carries: shared lighting, the laundry that turns over every changeover, any communal facility. That central array works alongside per-lodge roof PV, and it changes the connection picture, because a multi-unit or battery-plus-EV system will generally need a G99 application rather than the simple G98 notification a single small lodge uses.

This is the point where lodge sites begin to resemble the small-park model. If you are running a cluster of lodges with a reception and amenity building, our small self-catering parks page covers the site-wide sizing and the half-hourly meter approach that scale calls for.

Cost, payback and an indicative model

To make the economics concrete, consider a premium lodge with a hot tub kept hot through the season and a 7 kW guest EV charger on the deck, off the gas grid on electric heating. An 8 kW roof array with a 10 kWh battery toward the middle of the indicative range might generate around 7,000-7,500 kWh a year. Modelled against a hard-running hot tub, changeover hot water and daytime EV charging, a high share of that generation is self-consumed in season, and the battery carries the evening hot-tub and charging load. On assumptions like these the payback tends to sit toward the faster end of the holiday-let range, better than a hot-tub-free property, because the lodge’s load is both larger and better matched to generation. That is an illustrative model for scoping, clearly not a quote, and your figure depends on your tariff, your loads and your roof. The cost guide sets out what moves the number.

Off-season, a lodge exports under the Smart Export Guarantee like any holiday let, earning on generation it is not using during the quiet winter. Because a lodge’s high summer self-consumption already captures most of the value, the SEG income is the complement rather than the core of the case.

Compliance for lodges and cabins

Planning sensitivity is higher for lodges than for most cottages, because premium timber lodges are often sited in exactly the landscapes that attract scrutiny, AONBs, National Parks and elevated rural settings chosen for the view. Roof-mounted PV on a lodge is frequently permitted development, but conservation-area and highway-facing limits apply, and the visual-impact question is taken more seriously in a protected landscape. We favour discreet, non-highway-facing roof-mount and provide the visual-impact detail the authority expects. The solar panel planning rules set out where permitted development ends.

Grid connection depends on size. The smallest single lodge units can notify under G98; larger lodges, and any multi-unit or battery-plus-EV configuration, need a G99 application to the DNO before connection. Rural lodge sites can sit on constrained networks, so we check connection capacity early rather than at the end.

On tax, the position is the same as for the wider sector and it changed on 6 April 2025. The Furnished Holiday Lettings regime and its capital allowances were abolished, so a personally-held lodge can no longer write solar down as plant and machinery, while a company-held lodge may still treat solar as qualifying plant and use the Annual Investment Allowance depending on its structure. This turns entirely on ownership, so take your own tax advice; the government’s capital allowances guidance is the starting point, and our grants and funding routes page keeps the same honest line.

EV charging and the Workplace Charging Scheme

For a multi-lodge site offering guest charging, the OZEV Workplace Charging Scheme can help fund the sockets, currently up to 75% of cost capped at £500 per socket from 1 April 2026, using an OZEV-approved installer and chargepoints. Paired with on-site solar, that turns guest EV charging from a cost into a self-consuming load that draws down your own generation and adds a genuine listing feature at the same time.

Where lodges sit in the marketing picture

Eco-conscious guests are the core of the premium-lodge market, and visible renewables land harder here than in almost any other holiday-let segment. On-site solar is auditable evidence for a Green Tourism award, it reads well in listing photography, and it supports the sustainability story premium guests increasingly expect. For a lodge owner, the array is both a running-cost cut and a positioning asset, and the two reinforce each other over a letting season.

The premium guest and the running-cost story

A lodge competes on experience, and the guest paying a premium rate is often the guest most attuned to how the place is run. On-site solar reads to that guest as a property looked after rather than run down, and it lets the owner tell a running-cost story that competitors on grid power cannot. Two things follow from that. First, the lower running cost protects the margin on a unit that already carries a hot tub and often heating and EV charging, the very loads that make a lodge expensive to run. Second, the visible array and the sustainability credential earn their place in the listing, which in the premium and eco-conscious end of the market is where bookings are won. A lodge owner who has cut the season’s electricity cost and can point to the panels in the listing photos is doing two jobs with one investment, and over a letting season the two effects compound. It is worth modelling both the bill saving and the occupancy that a stronger listing supports, rather than treating the solar as a pure cost line.

Finance and the honest tax position

Because a lodge is a larger investment than a single cottage, the funding route matters, and here the April 2025 change bears repeating in plain terms. Under the old Furnished Holiday Lettings regime a lodge could be treated much like a trade for tax, with capital allowances on plant such as solar. That regime is gone. A personally-held lodge now sits in an ordinary property business and cannot write the array down as plant and machinery, while a lodge held in a genuine trading company may still be able to use the Annual Investment Allowance on qualifying plant. The difference between those two outcomes is entirely a question of structure and activity, and it is not one we can answer for you, so the honest advice is the same one we give on every page: take your own tax advice from an accountant who knows your setup. What we can say cleanly is what still applies regardless of structure, the Smart Export Guarantee on off-season export, and the Workplace Charging Scheme where you install guest EV sockets across multiple units. We would rather set out the position straight than imply a relief that may not survive contact with your accountant.

Common questions from lodge owners

Is a lodge a better solar case than a cottage? Usually, yes. A lodge’s hot tub runs harder, guest EV charging is close to standard, and both loads fall in the sunny season, so self-consumption and return tend to be higher than on a lighter-used cottage. The limited roof is the trade-off, which is why the battery matters more.

Can I fit enough panels on a single lodge roof? Often, with high-efficiency panels and a design that uses the best available pitch. Where the roof genuinely limits generation, the battery is sized to extract full value from what does fit, and a central-building array can add capacity across a multi-lodge site.

Do guests actually care about the solar? In the premium-lodge segment, yes. Eco-conscious guests choose greener stays and several owners now feature their solar and low running costs in the listing. It is auditable evidence for a Green Tourism award as well as a running-cost cut.

Will the install disrupt bookings? Roof work is scheduled into a changeover gap or the quiet season, and the only unavoidable outage is the short final grid connection, which we book for an empty period.

A lodge is, in solar terms, a cottage with the volume turned up: a harder hot tub, standard EV charging, a limited roof and a battery that matters more. The economics tend to be a little better than a cottage for exactly those reasons.
