Solar for Multi-Park Operators and Holiday Park Groups

Why multi-park groups get the best economics from solar across the portfolio

For a regional operator or group running several caravan and holiday parks, solar stops being a single-site decision and becomes a portfolio programme, and at that scale the economics improve markedly. A group can standardise the design once and roll it out across every park, spreading the capital and reducing the per-site cost through procurement scale. It can fund the whole programme through a group-level PPA or asset-finance framework, so each park draws on the same facility and deployment becomes effectively zero-capex. And it can run central monitoring and ESG reporting across every site, which turns a collection of separate installs into a single, board-level sustainability narrative that investors and leisure-property valuers increasingly expect to see. For groups whose energy cost is a board-mandated target, a coordinated solar roll-out is one of the cleanest ways to deliver both the cost reduction and the ESG reporting in one move.

The sector backdrop drives this hard. Site-wide energy has risen sharply across the sector since 2021, and for a group that cost is multiplied across every park, so the savings compound. The same guest pressure for sustainability credentials that affects a single park applies at portfolio level too, where a consistent green story across every site strengthens the group brand and supports bookings everywhere at once.

Portfolio roll-outs are already happening at scale in the sector, with larger operators committing significant sums to solar across dozens of parks at once, and the logic is the same whatever the group's size: a roll-out standardises design, spreads capital, and unlocks group-level PPA or asset-finance frameworks that make zero-capex deployment possible. The other advantage that only emerges at group scale is data. With central monitoring across every site, the board gets a single dashboard showing generation, savings and avoided carbon across the whole portfolio, which is exactly the kind of auditable ESG evidence that investors and leisure-property valuers increasingly ask to see. On-site solar is now treated by the major property advisers as a value-add on a leisure asset rather than a complication, so a group programme also quietly improves the saleability and valuation of every park in it.

What a typical install looks like and how it is sized

A multi-park group programme is sized across the portfolio rather than per site, typically running 500 kW to 5 MW in total, roughly 920 to 9,200 plus panels spread portfolio-wide, generating in the region of 460,000 to 4.6 million plus kWh a year and saving between 106 and over 1,058 tonnes of CO2 annually. The approach is to assess each park individually for roof condition, DNO capacity and planning, then standardise everything that can be standardised so the design, components and monitoring are consistent across the group. Half-hourly meter data and occupancy calendars are needed for every site, because a coastal park and an inland one will have different curves, and the roll-out can be phased so capital and installation effort are spread sensibly. Where individual sites are on constrained networks, battery storage can be deployed to self-consume while awaiting export capacity, keeping the programme moving rather than waiting on the slowest grid connection.

The seasonal-load logic that makes a single caravan park a strong solar case is amplified across a group, because the portfolio almost always spans different geographies and occupancy patterns. A coastal park in Wales and an inland park in the West Country will peak in slightly different ways, and modelling each one against its own occupancy calendar rather than a group average produces a much better-sized array per site. That is the difference between a roll-out that performs as promised and one that over-builds the quieter parks and under-builds the busy ones. The group view also helps sequence the work, starting with the parks that have the strongest pool-led self-consumption and the clearest grid position, so the early sites prove the economics and build board confidence before the harder, constrained sites are tackled.

Costs, payback and tax relief

A group programme typically runs £350,000 to £4 million plus rolled out across multiple sites, with a blended payback near 6 years. Tax treatment is where group scale needs care. The 100% Annual Investment Allowance covers qualifying plant up to £1m per year, and most individual park installs sit within that, but a group deploying more than £1m of solar in a single tax year will exceed the AIA cap on the balance. Above the cap, solar as a special-rate asset qualifies for the 50% First Year Allowance, with the remaining 50% relieved through writing-down allowances at 6%. Phasing the roll-out across tax years can keep more of the spend inside the AIA cap, which is worth modelling alongside the engineering programme. The Smart Export Guarantee pays for off-season surplus across the portfolio. Our cost guide sets out the group economics, and the funding page covers the allowances in detail. The reliefs behind that phasing are explained in capital allowances for caravan park solar. These cost and payback figures are illustrative estimates, not quotes.

Funding routes in detail

Group scale unlocks the strongest funding structures in the sector. Beyond the 100% Annual Investment Allowance and the 50% First Year Allowance for spend above the £1m cap, a group-level power purchase agreement framework allows zero-capex deployment across every park from a single contract, while group asset finance spreads the cost over a typical term and is usually EBITDA-positive from year one. Group PPA contracts use recognised BRE and Solar Energy UK templates, which also means the offtake obligation transfers cleanly with a site if a park is ever sold. For guest and staff EV charging across the portfolio, the OZEV Workplace Charging Scheme funds up to 75% of chargepoint cost, capped at £500 per socket from April 2026, up to a maximum of 40 sockets per applicant across all sites, and the scheme closes on 31 March 2027. 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. A framework lets each park draw on the same facility and gives the board one coherent funding picture.

Compliance and sector considerations

At group level, compliance is about doing the per-site work rigorously and then standardising. Each park is assessed individually for roof condition, DNO capacity and planning before being brought onto the standard design, because a coastal park in a National Park and an inland park on a strong network are genuinely different propositions. Every site's distribution must meet BS 7671 Section 708 for caravan and camping parks, with the usual pitch socket-outlet, RCD and IP requirements, and pool-equipped sites add the Section 702 pool zones. ESG disclosure is increasingly board-mandated for leisure assets tracked by the major property advisers, so central monitoring can be designed to produce the portfolio-wide reporting the board needs. The standard sector requirements apply at every site: permitted development for rooftop PV in England under Class J of Part 14 (above 50 kW, subject to the council's prior approval; Wales and Scotland have their own rules) with extra scrutiny in protected settings, G99 applications above 16 A (3.68 kW) per phase, and periodic inspection at the intervals set out in IET Guidance Note 3.
