Cotswolds boutique hotel group: 480kWp across four sites under PPA

A six-property Cotswolds boutique hotel group deployed 480kWp solar across four sites with the strongest roofs under a 20-year PPA. Zero capital outlay, immediate cash flow benefit, lower lifetime savings versus capital-purchased — but the structure fitted the group's capital constraints precisely.

Project overview

A Cotswolds boutique hotel group operating six properties — four with strong roof structures and two with planning constraints (listed buildings and conservation area) — deployed 480kWp solar across the four eligible sites under a 20-year Power Purchase Agreement. The hotel group retains zero ownership of the solar systems; a third-party developer installed, owns, and operates the systems and sells electricity to each hotel at a fixed-but-discounted tariff.

The challenge

The hotel group had been considering solar for three years but was structurally blocked. Capital purchase was unavailable due to debt covenants on the property portfolio (refinanced 2022 with restrictive new-debt clauses). Green loans were similarly precluded. Operating leases were considered but the implied rate (8.5% effective) made the case marginal. The hotels had visible decarbonisation pressure from corporate event clients but were running out of internal options.

Structure and economics

Specialist hospitality-PPA developer funded the £384,000 turnkey installation across the four sites. PPA terms: 20-year fixed-rate-with-RPI tariff at 16.5p/kWh (versus prevailing grid rate 23.5p), so each hotel saves 7p/kWh on consumed solar. Group-level annual saving in year one: £82,000 across the four sites. Saving grows at 2.0% real annually (RPI-linked tariff escalator) versus expected grid-tariff inflation of ~2.5% real, meaning the spread widens over the contract life.

How we got there

  1. Step 1

    Q1: Multi-site feasibility review across all six hotels. Two ruled out for structural and planning reasons — solar deemed not financially viable for those sites alone.

  2. Step 2

    Q2: Capital structure review with hotel group CFO confirmed debt covenant constraint on direct capex. PPA structure recommended as the practical route to project viability.

  3. Step 3

    Q3: PPA developer screening across three specialist hospitality PPA providers. Selection on price, contract quality, exit terms, and counterparty financial covenant.

  4. Step 4

    Q4: Lease provisions amended with each property's legal team to allow third-party solar installation. Property-level PPA contracts executed with each hotel as offtaker.

  5. Step 5

    Year-2 Q1-Q2: Phased installation across the four sites, sequenced to minimise off-season disruption.

  6. Step 6

    Year-2 Q3: All four sites commissioned and producing. Group-level monitoring portal live.

Outcome

Year-one combined cash benefit: £82,000 across the four sites. The hotel group avoided £384,000 capex outlay (which would have been precluded by debt covenants in any case). Net 25-year saving projected at £2.4m versus £4.1m if the same systems had been capital-purchased — the PPA developer captures the difference as their return on capital.

What this case taught us

  • Capital-constrained hospitality groups have very limited options outside PPA — operating lease pricing rarely beats PPA economics for the same risk profile.
  • Listed-building and conservation-area constraints often eliminate ~30% of group portfolios. The remaining sites can still produce material group-level savings.
  • Long-tenure PPAs (20 years) are essential to the developer business model — shorter terms (10 years) typically aren't available because the developer cannot recover capex within the period at acceptable IRR. Hotels uncomfortable with 20-year contractual horizons should reconsider whether PPA is the right structure.

Frequently asked questions

Why did the Cotswolds hotel group use a PPA for four sites rather than capital purchase?
The hotel group's finance director identified three reasons for the PPA preference: (1) the group's bank facilities were fully drawn for a room renovation programme; (2) two of the four hotels were leasehold, making capital purchase on those sites legally complex without freeholder consent; (3) the group's accountants advised that, while the FYA was available, the group's Corporation Tax profile (with significant interest deductions reducing taxable profits) meant the capital allowance benefit was less compelling than for a profitable manufacturer. A zero-capital PPA delivering guaranteed savings from month one was the pragmatic choice.
What electricity cost savings did the Cotswolds hotel group achieve across four sites?
The 480kWp total installation (approximately 120kWp per site) generates around 410,000 kWh/year across the portfolio. Hotels typically achieve 75–85% self-consumption given 24-hour kitchen, heating, cooling, and common area loads. At an average PPA rate approximately 18% below the hotels' grid tariff, annual savings across all four sites are approximately £65,000–£80,000. The PPA's 2.5% annual rate escalation is below the group's modelled electricity price escalation of 3.5%, meaning the saving grows in absolute and real terms over the contract.
How are multi-site solar PPAs structured for hospitality groups?
Multi-site hospitality PPAs are typically structured as a single master agreement covering all sites, with site-specific schedules detailing system size, metering, and local electricity tariff benchmarks. The single contract simplifies procurement, legal review, and ongoing management. The PPA provider typically takes responsibility for all DNO consents, planning permissions, installation, and maintenance across the portfolio. Payment is consolidated to a single monthly invoice, simplifying the hotel group's accounts payable process. Most PPA providers require a minimum portfolio size of 200kWp to offer multi-site consolidated pricing.
What happens to the PPA if one of the hotels is sold?
PPA contracts for multi-let hospitality portfolios typically contain asset disposal clauses: the seller can either assign the PPA obligation to the buyer (most common, as the solar system has a positive value), or make a break payment to the PPA provider covering their modelled lost returns. For buyers, inheriting a well-structured PPA at below-market electricity rates is typically seen as a positive asset. The purchase contract should include a solar due diligence schedule and legal opinion on the assignability of the PPA. Standard Hotelier/CBRE property schedules now routinely include solar and energy contract disclosures.
