Solar for Holiday Park Amenity Blocks, Pools and Clubhouses

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 the best place to start.

The wider sector context applies with extra force here. Energy costs have risen sharply 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 is easy to show guests and to cite in a Green Tourism application.

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 standard practice on leisure-building projects.

What a typical install looks like and how it is sized

For park amenity and leisure buildings a system is usually designed 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. The bar, restaurant and entertainment refrigeration and lighting loads add further in-season demand, and battery storage is worth modelling where the venue runs into the evening. The large, mostly unshaded leisure-building roofs usually leave plenty of room, but on older leisure complexes a structural survey comes first because the roof must carry the array safely. As always, the starting point is at least twelve months of half-hourly data overlaid with 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, the first project usually goes 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, not 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. These cost and payback figures are illustrative estimates, not quotes.

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 is a certification scheme, not a grant; on-site solar can count as evidence in an application, so check the scheme's current criteria. The right route depends on 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 currently applies to residential and charity buildings only (until 31 March 2027), 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 the PV connection has to be designed 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 an older roof should never be assumed suitable. The wider park compliance picture also applies: rooftop PV on commercial leisure buildings generally falls under permitted development in England under Class J of Part 14 (above 50 kW, the council's prior approval of design and appearance applies; Wales and Scotland have their own rules), with greater scrutiny in protected and coastal settings; a G99 application is required above 16 A (3.68 kW) per phase and capacity-constrained networks need a connection study before sizing; and periodic inspection of the site installation follows the intervals set out in IET Guidance Note 3, which matters on a guest-occupied leisure building. If the roof fails that check, rooftop vs ground mounted solar caravan parks compares the ground-mount alternative.
