South West retail chain: 720kWp across 9 stores under operating lease

Project overview

A South West specialist retail chain operating 14 stores deployed 720kWp solar across nine stores (the 9 with viable rooftops) under a single consolidated 8-year operating lease. Total system value £575k. The retailer chose operating lease over capital purchase or finance lease specifically because gearing capacity preservation was strategically important — an upcoming store-acquisition programme required all balance sheet headroom.

The challenge

The retailer faced a strategic finance decision rather than a pure project finance decision. Capital purchase would have absorbed £575k of cash — material against the retailer's working capital position. More importantly, capital-purchased solar would have shown as ~£545k of fixed assets on the balance sheet, with the corresponding cash outflow visible in the cash flow statement — both visible to the bond covenant calculations being assessed by the retailer's acquisition lender. Operating lease structure kept the asset entirely off-balance-sheet (under FRS 102 small-entity reporting that the retailer uses) while delivering the operational benefit.

Structure and economics

8-year operating lease with leasing company at £92k/year fixed rental across all nine sites combined. Leasing company holds legal title to all systems; the retailer holds operational use through a multi-site lease arrangement. Year-one combined electricity saving £220k across the nine sites — net of £92k lease payment, retailer captures £128k year one cash benefit. Lease payments are P&L expenses (no balance sheet recognition under FRS 102 small-entity), preserving headline gearing metrics for the acquisition financing assessment.

How we got there

1. Step 1

   Q1: Multi-store feasibility — DNO connection studies and rooftop structural surveys across all 14 stores. Five excluded for structural, planning, or DNO-cost reasons.

2. Step 2

   Q2: Lease structure analysis vs alternatives. Capital purchase, green loan, finance lease, operating lease, and PPA modelled side-by-side with explicit balance sheet impact assessment for each. Operating lease selected based on gearing-preservation priority.

3. Step 3

   Q3: Operating lessor competitive process across three specialist energy-asset leasing companies. Selected on rate, structure flexibility, and end-of-lease arrangements (option to acquire at depreciated book value).

4. Step 4

   Q4: Single consolidated lease facility executed across the nine sites. Phased installation began.

5. Step 5

   Year-2 Q1-Q3: Phased installation across the nine sites, scheduled around store trading patterns. Each store individually commissioned with site-level monitoring.

6. Step 6

   Year-2 Q4: All nine sites operational. Lease repayments commencing as installations are individually accepted by the leasing company.

Outcome

Year-one combined electricity saving across nine stores: £220k (driven by daytime-heavy retail demand profile with ~85% self-consumption). Net of £92k annual lease payment, year-one cash benefit £128k. Bond covenant headroom preserved — the acquisition financing closed three months later without any covenant difficulty around the solar capex. Cumulative 25-year saving projected at £2.1m versus £3.4m if capital-purchased — the leasing company's margin is the difference.

What this case taught us

• Operating lease is rarely the cheapest structure on lifetime cost — but balance sheet treatment can be the deciding strategic factor when capital allocation choices are constrained. The retailer prioritised covenant-headroom preservation over lifetime savings, and the structure delivered exactly that.
• Multi-site portfolio lease structures simplify administration significantly versus per-site arrangements. Single lease, single counterparty, single administrative interface across nine stores.
• FRS 102 small-entity treatment of operating leases (off-balance-sheet) differs from FRS 102 full or IFRS 16 (typically capitalised). The structural advantage applies only where the relevant accounting framework permits it. The retailer's use of small-entity FRS 102 was explicit and confirmed with auditors before structuring the lease.
