Why the case has shifted against biomass
The 2010-2020 case for hotel biomass rested almost entirely on RHI tariff support — typically 2.5-6p/kWh thermal across the relevant biomass tariff bands. RHI closed to new applicants 31 March 2021. Without RHI, biomass economics rest on woodchip or pellet fuel pricing alone, currently 4-7p/kWh thermal delivered (substantially above 2018-2020 levels). Combined with biomass capex (typically £80,000-£250,000 for hotel-scale plant), boiler refurbishment cycles (15-20 year typical life with substantial mid-life refurbishment cost), and BSL accreditation maintenance, total cost of ownership for hotel biomass over 25 years is typically £400,000-£900,000.
When biomass still wins for hotels
Three specific scenarios where biomass still delivers superior economics for UK hotels in 2026: (1) rural country house properties with substantial on-site woodland providing essentially free fuel via in-house chipping operations; (2) large country house estates with district-heating opportunity across multiple buildings (main house, stable blocks, cottages, function rooms) where the capex per kWh thermal is spread across substantial demand; (3) properties with existing BSL-accredited biomass infrastructure approaching mid-life refurbishment where the refurbishment capex is small compared to alternative-pathway replacement capex.
Solar vs biomass FAQs
Does biomass still make sense for hotels in 2026?
Limited. RHI (Renewable Heat Incentive) closed to new applicants in 2021. Without subsidy, biomass operating economics depend heavily on woodchip/pellet pricing — typically 4-7p/kWh thermal. For most hotels, solar PV plus heat pump electrification delivers materially better lifetime economics than biomass.
Where does biomass still work for hotels?
Rural country house hotels with on-site woodland (free fuel), district heating to multiple buildings on a large estate, or properties with existing BSL-accredited biomass infrastructure approaching mid-life refurbishment. Otherwise, solar + heat pump is the dominant 2026 pathway.
Combined solar + biomass — viable hybrid?
Occasionally. Country house properties running biomass for heating may benefit from solar PV covering electrical demand and biomass continuing to cover hot water and space heating. We model both routes during feasibility.
