Leeds is home to one of Yorkshire's most concentrated commercial property markets. From the logistics hubs at Junction 45 of the M1 to the manufacturing estates at Hunslet and Holbeck, the office parks at Thorpe Park and Leeds Valley, and the retail distribution centres around Morley — the commercial solar opportunity across the city is significant.
The Financial Case for Leeds Commercial Solar
A typical Leeds commercial warehouse or manufacturing unit with a 500kW solar system generates approximately 450,000–500,000 kWh per year. At a blended electricity cost of 24p/kWh, with 80% of generation self-consumed, this saves £86,400–£96,000 annually. The remaining 20% exported via Octopus Flux earns £5,400–£9,000 per year.
- Total annual benefit: £91,800–£105,000
- Headline system cost (500kW): £450,000–£550,000
- Full Expensing (Year 1 tax saving at 25%): £112,500–£137,500
- Effective net cost after tax: £337,500–£412,500
- Payback (adjusted for tax relief): 3.5–4.5 years
Best Sectors in Leeds for Commercial Solar
Leeds businesses with the highest solar ROI are typically those with high daytime electricity consumption and large roof areas:
- Logistics and warehousing (Junction 45, Thorp Arch): Large unshaded roofs, 24-hour operations meaning high overnight battery discharge value.
- Food manufacturing and cold storage (Morley, Rothwell): High daytime loads from refrigeration and processing equipment.
- Retail distribution (DIRFT, Birstall): Extensive roof areas with straightforward trapezoidal steel roof installation.
- Office parks (Thorpe Park, Wellington Place): Lower consumption but strong Corporate Social Responsibility and EPC improvement drivers.
G99 Grid Connection in Leeds
Commercial systems above 50kW require a G99 grid connection application to Northern Powergrid (Leeds's DNO). Typical approval timescales are 8–16 weeks for straightforward applications. YEERS manages the complete G99 process including technical modelling and protection relay coordination.
