How a beloved heritage pub dramatically reduced its energy bills and improved sustainability through a bespoke solar, battery storage, and heat pump system — designed and installed by YEERS.
The Crown & Anchor, a long-standing and well-loved pub in Newport, faced a pivotal moment in 2024. Following a change in management, the new owners confronted a major operational challenge: excessive monthly energy bills that were eroding profit margins.
An initial review revealed an Energy Performance Certificate (EPC) rating of E, driven by the building's size, commercial usage, and insufficient insulation. Recognising the need for a long-term, future-proof solution, the owners partnered with Yorkshire Renewable Systems Ltd (YEERS) to design and implement a comprehensive renewable energy strategy.
Their goal was clear: dramatically reduce energy costs, improve efficiency, and move the business as close to energy independence as possible.
Excessive energy bills described as "cumbersome" — directly eroding monthly profit margins.
EPC rating of E — posing risk to sustainability, tenant comfort and long-term asset value.
Peak-hour demand spikes — heavy evening consumption coinciding with expensive grid tariff rates.
Commercial scale — requiring a robust, scalable, and future-proof solution with measurable ROI.
YEERS engineered a tailored three-component system designed specifically around the Crown & Anchor's operational profile — high daytime generation, heavy evening consumption, and tenant heating requirements.
A carefully blended combination of high-efficiency JA Solar and Trina Solar panels ensures strong generation across all weather conditions — maximising output during peak sunlight whilst maintaining stable generation during overcast periods.
The SigenStor EC 12.0 TP hybrid inverter intelligently routes energy where it is needed most — acting as the system's brain. Paired with a 20kW battery bank, surplus solar is stored and released during peak evening hours.
Dedicated to the second-floor tenant flat, the Logic Air heat pump was configured to run directly from the solar array whenever possible — delivering low-cost renewable heating and improving the building's EPC rating.
The three components form a cohesive energy ecosystem where generation, storage, and consumption work in harmony to minimise waste and maximise savings throughout the day.
The 36-panel mixed array generates substantial renewable electricity throughout the day. JA Solar panels maximise output during peak sunlight, whilst Trina Solar panels maintain consistent performance in overcast and low-light conditions — ensuring a stable generation curve from dawn to dusk.
The SigenStor hybrid inverter intelligently routes surplus daytime solar energy into the 20kW battery bank. This stored energy is then deployed during the pub's busiest evening hours — precisely when demand spikes from lighting, kitchen equipment and customer activity, and grid prices are at their highest.
The Logic Air heat pump for the tenant flat was configured to prioritise the solar array as its energy source. This ensures the second-floor resident benefits from low-cost, renewable heating year-round — reducing the building's overall energy footprint and improving EPC performance.
Any excess energy not consumed by the pub or stored in the batteries is exported back to the National Grid via the Smart Export Guarantee scheme — creating a new and ongoing revenue stream that further improves the return on investment for the owners.
The integrated renewable energy system delivered tangible financial and environmental benefits from day one of operation.
By prioritising self-generated solar power and deploying stored battery energy during expensive evening peak hours, the Crown & Anchor has significantly reduced its monthly utility bills — directly improving profit margins and reducing financial pressure on the business.
Excess energy not used by the pub or stored in the battery system is exported back to the grid through the Smart Export Guarantee, generating additional income and further improving the overall return on the renewable energy investment.
The adoption of a solar-powered heat pump for heating, combined with the wider renewable energy system, positions the property to move from an EPC rating of E to a substantially higher level — future-proofing the asset and improving its market value.
The solar-powered Logic Air heat pump provides the on-site tenant with highly cost-effective renewable heating and reduced electricity costs, improving day-to-day comfort, affordability, and overall tenant satisfaction.
The Crown & Anchor's transformation demonstrates how traditional hospitality businesses can embrace modern sustainability solutions without compromising operational performance — proving that even heritage commercial properties can thrive in a low-carbon future.
