Park Amenity & Leisure Buildings (Pools, Bars, Entertainment): Solar panels for caravan parks

Why park leisure buildings are the fastest-payback solar on most caravan parks

If a caravan park has a swimming pool, the pool is almost always the single biggest electrical load on the whole site, and that makes the leisure buildings the most rewarding place to put solar. Indoor and outdoor pools draw heavily on pumps, heating and dehumidification, and they run hardest in exactly the same months when solar generates most, so self-consumption is excellent and pool heating paired with solar is one of the fastest-payback combinations anywhere in the sector. Add the bars, restaurants and entertainment venues, with their heavy refrigeration and lighting loads in season, and the amenity and leisure complex becomes a concentration of high-value daytime demand sitting under large, mostly flat or low-pitch roofs that are close to ideal PV surfaces. For an owner wanting the strongest possible business case from a first solar project, the leisure building is usually where we point them.

The wider sector context applies with extra force here. Energy costs have roughly doubled since 2021, and the pool is where a great deal of that increase lands, because pool plant runs whether the bar is busy or not. Fixing that cost for two decades transforms the economics of running a pool, and because the leisure complex is also the guest-facing heart of the park, on-site solar visible there feeds directly into the Green Tourism story that increasingly influences bookings.

The leisure complex is also the natural home for guest EV charging, and the two technologies belong together. Chargepoints sited near the bar, restaurant or pool absorb daytime solar generation at close to full self-consumption, and a battery in the same plant area lets you charge cars from stored solar into the evening peak without overloading the supply that already feeds heavy pool and refrigeration loads. That matters on a leisure building precisely because it is the part of the park with the most concentrated demand, so pairing the chargers with the array, rather than bolting them onto an already-stretched grid connection, often defers or avoids an expensive DNO upgrade. Designing the PV, the battery and the chargers as one system is something we do as standard on leisure-building projects.

What a typical install looks like and how we size it

For park amenity and leisure buildings we usually design a system in the 50 to 400 kW range, roughly 90 to 740 panels across about 400 to 2,500 square metres of large flat or low-pitch leisure-building roof, generating in the region of 45,000 to 370,000 kWh a year and saving between 10 and 85 tonnes of CO2 annually. Sizing is led by the pool plant, the dominant load, because pumps, heating and dehumidification give a steady, high daytime baseload that the array can offset directly. We layer in the bar, restaurant and entertainment refrigeration and lighting loads, which add further in-season demand, and we model battery storage where the venue runs into the evening. The large, mostly unshaded leisure-building roofs usually give us plenty of room, but on older leisure complexes a structural survey comes first because the roof must carry the array safely. As always we pull at least twelve months of half-hourly data and overlay the occupancy calendar.

Pool heating plus solar deserves singling out because it is one of the fastest-payback combinations in the whole sector. Pool pumps, heating and dehumidification are the single largest electrical load on most parks that have a pool, and they run hardest in the same months solar generates most, so self-consumption is typically excellent and very little of the generation is wasted to export. That is why, when an owner is weighing where to start, we usually steer the first project toward the pool building rather than spreading a smaller array thinly across reception and shop roofs. Get the pool covered first, and the rest of the site can follow in a second phase once the economics have proven themselves.

Costs, payback and tax relief

A park leisure-building project typically runs £45,000 to £360,000 fully installed, with a simple payback near 5.5 years, the fastest in the sector, driven by the pool's high, sun-aligned self-consumption. After payback the generation is effectively free for the life of the system. The 100% Annual Investment Allowance lets most park businesses write off the full cost of solar, inverters, mounting and storage against profit in year one, up to the cap, worth up to a quarter of the value back in tax for a limited company; solar is a special-rate asset, so it uses the AIA rather than full expensing, and a single leisure-building install sits well within the cap. The Smart Export Guarantee pays for off-season surplus, but with a pool the value is overwhelmingly in avoided import during the operating months. Our cost guide works through the pool-plus-solar economics, and the funding page covers export tariffs and EV support.

Funding routes in detail

The leisure building's fast payback makes every funding route look good. The 100% Annual Investment Allowance is the foundation, delivering up to a 25% effective tax saving in year one. A power purchase agreement gives zero-capex deployment with day-one savings against your tariff, which is attractive when capital is committed elsewhere on the park, and because the self-consumption is so high the PPA savings on a pool-led system are strong. Asset finance spreads the cost over a typical term and is usually EBITDA-positive from year one given the rapid payback. If you add guest or staff EV charging near the leisure complex, the OZEV Workplace Charging Scheme funds up to 75% of chargepoint cost, capped at £500 per socket from April 2026, up to 40 sockets, and daytime charging absorbs solar at near-100% self-consumption. Green Tourism accreditation is not a grant but turns the visible leisure-building array into a booking and pricing advantage. We model the route against your cash flow and the speed of the payback.

It is worth being clear on one point that surprises owners: the 0% VAT relief many have heard about for solar applies to residential and charity buildings only, so it does not apply to a commercial leisure complex on a holiday park. That is why the Annual Investment Allowance, rather than a VAT saving, is the relief that does the work here. Cost per kW on a leisure-building array is typically in the region of £750 to £950 above 100 kW, and because these systems are usually toward the larger end of a single park's footprint, the per-kW cost tends to sit at the more efficient part of that band. The fast payback also means asset finance is comfortably EBITDA-positive from year one, so even a fully financed pool array typically improves the park's cash position from the first quarter rather than the second or third year.

Compliance and sector considerations

The leisure building has its own electrical safety considerations. Pool plant rooms fall under BS 7671 Section 702 for swimming pools and other basins, with specific electrical safety zones that we design the PV connection around, while commercial kitchen and bar refrigeration is unaffected by the PV itself. The most important sector-specific check for this building type is structural: older leisure complexes need a structural survey before any rooftop PV, because the roof must carry the array, and we never assume an older roof is suitable. The wider park compliance picture also applies: rooftop PV on commercial leisure buildings generally falls under permitted development within size limits, with greater scrutiny in protected and coastal settings; a G99 application is required above 17 kW per phase and capacity-constrained networks need a connection study before sizing; periodic inspection of the site installation is recommended at intervals not exceeding three years under IET Guidance Note 3; and the SPF1981 v3 rooftop fire safety standard is increasingly an insurer requirement, which matters on a guest-occupied leisure building.

How we approach this kind of project

We size from your half-hourly meter data and occupancy calendar, leading with the pool plant load because that is what drives the return, and we model the bar, restaurant and entertainment loads alongside it. A structural survey of the leisure-building roof comes first on older complexes, followed by a full BS 7671 site-electrics survey that covers the Section 702 pool zones, so any necessary work is captured in one coordinated plan. We submit the G99 grid application early, design for self-consumption or add battery storage where export capacity is tight or the venue runs into the evening, and deliver a fixed-price proposal with a 10-year insurance-backed workmanship warranty. Coastal parks get a salt-resistant specification, and rooftop work on the leisure building is contained and screened from guest areas, with the disruptive work scheduled for the closed or quiet season.

Because the leisure building is guest-occupied, the SPF1981 v3 rooftop fire safety standard matters more here than on a back-of-house amenity block, and we specify to it as standard, which an increasing number of insurers now require. Our certifications back the rest of the work: MCS commercial certification for SEG eligibility, NICEIC or NAPIT for the electrical work including the Section 702 pool zones, RECC and TrustMark for consumer protection, and OZEV approval where guest EV charging is added near the complex. The final grid connection is the only unavoidable outage, a window of a few hours that we book for a low-occupancy period so the bar, restaurant and pool keep trading, and we phase any structural remediation on an older roof so the building stays usable throughout.

An illustrative example

As an illustrative composite based on typical UK park leisure-building projects, and not a real named client: a coastal holiday park with an indoor heated pool, a clubhouse and amenity blocks, whose site-wide bill had roughly doubled over three years with the pool plant the largest single load, installed around 182 kW of solar across the pool building, clubhouse and amenity-block roofs, generating in the region of 165,000 kWh a year. In-season self-consumption on the pool plant and shower-block hot water sat around 84%, giving an annual saving near £41,000 and a payback close to 5.6 years, with the full cost relieved in year one under the Annual Investment Allowance and a salt-resistant coastal specification used. The visible array on the leisure building supported a Green Tourism Gold award, with a live-generation display added in reception. The figures are illustrative and depend on your pool, roof, occupancy and tariff.
