Commercial & large residential properties

Most commercial roofs exist simply to protect the building underneath.
The question is:
What could your roof generate?
But large roofs can actually become electricity-generating assets.
Warehouses, schools, agricultural buildings and commercial properties often have thousands of square metres of roof space exposed to sunlight every day.
That space could generate significant electricity value.
Warehouse roof:
3,000 m²
Potential solar system:
450 kWp
Estimated electricity generation:
400,000 kWh per year
Potential electricity value:
£80,000 – £140,000 annually
Curious what your roof could generate?
Businesses across the UK are facing the same challenge:
Energy prices remain volatile
Budget forecasting is increasingly difficult
Grid dependence exposes businesses to long-term risk
If you manage or own property with large roof space, you may already have the solution you’re just not using it yet.
Your roof could be generating your own electricity.

Most organisations think solar means:
Expensive upfront investment
Disruptive installation
Complex technical management
We approach it differently.
We treat solar as a managed on-site energy asset that:
Reduces reliance on the grid
Creates long-term cost certainty
Converts unused roof space into power generation
Strengthens sustainability and ESG credentials
The Solar Roof Value Report explains the general potential of commercial roofs.
If you'd like to see what solar could generate for your specific building, the next step is a Solar Feasibility Assessment.
We analyse your:
Roof or land space
Energy consumption profile
Potential system size
Estimated energy generation
Potential savings
ROI timeframe
Carbon reduction impact

If the assessment shows strong potential, we manage the full project:

Techinal design

Grid applications

Installation

Maintenance

Solar systems perform best when actively managed.
We provide ongoing:
Performance monitoring
Preventative maintenance
System optimisation
Long-term asset management
Ensuring your system continues delivering measurable savings for years to come.


Solar works best for buildings with large roof space and consistent daytime electricity use.
The following properties often see the greatest benefit.
Commercial property owners
Warehousing and logistics sites
Schools and academies
Farms and agricultural operations
Leisure and sports facilities
Multi-site property portfolios
Large residential properties
If your property has large roof space and daytime energy use, there is often significant opportunity.
