Solar Grants for UK Hotels 2026 | Funding & PPA Specialists

Why solar economics work well for UK hotels

Hotels combine three things that make solar PV unusually well-suited: high electricity demand from 24/7 operation, exposure to the highest commercial electricity unit rates in the UK (hospitality regularly sits 8–12% above industrial rates due to half-hourly profile peakiness), and roof areas that are generally underused for revenue purposes. The unit-rate exposure is the key driver — every kWh of solar you self-consume displaces grid electricity at 24p–32p in 2026 prices, against an SEG export rate of 6–18p. Self-consumption is everything.

Hotel groups have moved aggressively into commercial solar over the last 36 months. Premier Inn, Travelodge, Hilton, Marriott franchise operators and a long tail of independent groups are now several years into multi-site PV programmes. The economics are clear once you model them properly; the constraint is funding structure rather than viability.

Why most hotel solar projects don’t use grants

Direct solar grants — IETF, PSDS, REPF — generally don’t fit hotels. IETF is for energy-intensive manufacturing. PSDS is for public sector. REPF is for rural enterprise (so applies to country-house hotels and rural pubs but not urban or city-centre hotels). For most hotel projects, the funding stack is:

• Full Expensing — 25p back per £1 of capex via corporation tax for any UK incorporated hotel operator
• Power Purchase Agreement — for hotels that prefer zero capex and longer-term commitment
• Asset finance / leasing — for hotels that want to spread capex over 5–7 years against the cash savings
• Smart Export Guarantee — recurring revenue on exported kWh (smaller in hotels because of high self-consumption)

About 65% of the hotel solar projects we have supported in the last 24 months have used Full Expensing as the primary funding mechanism. About 25% have used PPAs (mostly the larger groups). The remaining 10% have qualified for REPF as rural-located operations.

Sub-sector fit by hotel type

City-centre business hotels. Mixed fit. High electricity demand makes the case strong, but city-centre roof access is often constrained, and DNO connection costs in central London, Manchester and Birmingham have risen sharply. Most projects are sub-300kWp and pay back in 5–7 years.

Suburban and airport hotels. Strong fit. Ample flat roof, predictable demand profile, easier DNO connection. Most projects are 200–500kWp.

Country house hotels and resort destinations. Excellent fit. Roof area, ground space if needed, REPF qualification (if rural), high-end electricity exposure on premium tariffs. Average project size 250–600kWp.

Boutique, smaller independent hotels. Often viable but transaction costs of grant + tax modelling are heavy on smaller projects. Single-site projects under 100kWp typically work better with a simple Full Expensing + cash-funded route than with a PPA or grant.

Restaurants and pubs. Variable. The headline numbers are usually fine but small roof areas (often 60–200 kWp installable) mean lower absolute savings; for many, the answer is “wait until your gas boiler needs replacement and bundle solar into a wider energy-system upgrade”.

Multi-site groups. Usually the strongest economics because you amortise transaction costs across multiple sites. Groups with 8+ properties typically run a programmatic solar rollout with one master design framework. We have supported groups of 4 to 38 properties through programmatic delivery.

PPA structures for hotels

A solar PPA is the most common funding route for larger hotel groups because it requires no capex, no balance sheet impact (under most older IFRS interpretations — see caveat below), and provides a guaranteed cheaper cost per kWh from year one. The structural shape:

• A funder (usually a specialist PPA investor or asset-management arm of a large utility) pays for and owns the PV
• The funder takes a 20–25 year roof lease at nominal rent
• The hotel signs a Power Purchase Agreement to buy the solar electricity at a fixed pence/kWh rate, usually 6–9p below grid prices
• The funder recovers their capex through the off-take payments over the term
• At end of term, the asset usually transfers to the hotel for £1 (or there is a further off-take period)

The two negotiation points that matter most:

Tariff escalator. PPAs include an annual rate increase. The escalator is normally CPI, RPI or a fixed percentage (1.5–3%). Over 25 years the cumulative cost differential between CPI and RPI escalation is 18–22% — on a £4m off-take total, that’s £750k+ of difference. We always negotiate caps on the escalator.

Buyout schedule. Most PPAs allow you to buy out the asset from year 7 or 10. The buyout schedule usually starts at 80–85% of nominal asset value and decays. Hotels selling or refurbishing properties need clean buyout terms — we have seen PPAs that effectively block hotel sales because the buyout was prohibitively expensive.

IFRS 16 treatment. PPAs that contain a leased asset (the PV system itself, not just the land) may be brought on balance sheet under IFRS 16. This depends on how the contract is drafted — explicitly purchasing kWh (not capacity) and giving the funder operational control of the asset usually keeps the PPA off balance sheet. Listed hotel groups must take audit advice on this.

Battery storage in hotels

Hotels are an excellent fit for battery storage because the load profile has a strong evening peak (food service, room loads, kitchen ventilation) that lines up with sunset, when PV output is dropping. Adding a 100–200 kWh battery to a 300 kWp PV system typically lifts self-consumption from 70% to 88%, which translates to a 22–28% improvement in annual savings.

Battery economics on hotels are particularly favourable in 2026 because dynamic SEG tariffs (Octopus Outgoing Agile, EDF Variable, etc.) pay 25–40p/kWh during system peak windows, which often coincide with hotel demand peaks. The battery becomes both a self-consumption tool and an export-arbitrage tool.

How seasonal demand affects sizing

Most hotels have a strong seasonal demand profile — rural and country house hotels peak in summer, city-centre business hotels often peak in autumn business travel periods, and seaside resorts have very strong July–August peaks. Solar generation peaks May–August, so the alignment with demand varies significantly by hotel type.

This matters for sizing. A summer-peaked rural hotel in Cornwall achieves 85–90% self-consumption on a 300kWp PV system. A winter-peaked city-centre business hotel in Manchester achieves 65–72% self-consumption on the same system. The capex is the same; the savings are 20–25% different. Sizing has to be done off the actual half-hourly meter data, not generic profile assumptions.

Visual and planning considerations

City-centre and listed hotels face a planning constraint not present in industrial sectors. Most listed buildings cannot take roof-mounted PV without listed building consent, which is typically refused. The workable answers:

• Solar canopies on car parks (separate planning consent, not on the listed asset)
• PV on adjacent service buildings, plant rooms or boundary buildings
• Building-integrated PV (BIPV) tiles — emerging but cost-prohibitive at present (£3.50/Wp+)
• Off-site PPAs through a sleeved supply contract (does not require any PV on site)

Sleeved off-site PPAs are an emerging answer for listed and central-London hotels — you contract for solar generated off-site (typically a ground-mount in a different region) and the supplier sleeves it into your supply. Tariff economics are weaker than on-site (no avoided distribution and transmission charges) but it is often the only viable route for heritage assets.

How to start

Hotel projects typically start with a 30-minute call once we have your annual electricity spend and rough roof information. The funding review form takes four minutes; we come back within one working day with an outline funding stack and project size estimate. For multi-site groups, we usually arrange a workshop with the procurement and FM lead — half a day, free of charge, that produces a programmatic delivery plan covering the whole estate.
