Solar PV continues to play an increasingly important role in the UK’s transition towards cleaner, more affordable energy, with new figures showing a significant rise in installations across the country.
Recent analysis highlighted by Energy Live News shows that UK Solar PV installations have increased by more than 400% since 2019, rising from 53,044 annual installations in 2019 to 269,176 in 2025. Momentum has continued into 2026, with almost 192,000 installations recorded between January and August alone.
For Westville Group, these figures reflect a trend we are seeing first-hand, with Solar PV becoming an increasingly important part of projects delivered for Local Authorities and social housing providers.
Growing Demand for Solar PV
With energy costs remaining a major concern for households, Solar PV provides an opportunity to generate renewable electricity directly from the home, reducing reliance on electricity purchased from the grid and helping residents take greater control of their energy use.
As demand grows, the opportunity extends well beyond individual household installations.
Local Authorities and housing providers are increasingly looking at how Solar PV can be deployed across larger property portfolios, helping improve the energy performance of their housing stock while delivering tangible benefits for residents.
This creates a need for experienced contractors capable of taking Solar PV from individual installations to coordinated programmes involving tens, hundreds or potentially thousands of homes.
Westville’s Solar PV Capabilities
As a Tier 1 contractor, we have the experience, infrastructure and technical capabilities required to deliver Solar PV at scale.
We have seen Solar PV installations increase across our own Local Authority projects, with renewable technology becoming a growing part of the energy-efficiency programmes we deliver.
Our service includes initial property assessment and system design, through to installation, testing, commissioning and monitoring.
For large-scale programmes, this coordinated approach is particularly important. Delivering Solar PV across a substantial housing portfolio requires careful programming, supply chain management, quality control and communication with residents, alongside consistent installation standards from one property to the next.
Westville has the teams and systems in place to manage these requirements while giving clients a single, experienced delivery partner throughout their programme.
Residents Seeing the Difference in Their Energy Bills
For Local Authorities and housing providers, the success of a Solar PV programme is ultimately measured by the difference it makes to the people living in those homes.
Across our projects, residents are already reporting significant reductions in their electricity costs following the installation of Solar PV, with some households seeing an immediate difference in the amount of energy they need to purchase from the grid.
One resident saw their monthly electricity costs fall from £65 to just £20, while also benefiting from improved loft insulation:
“It’s brilliant, the house is so much warmer since the loft insulation was installed. The solar panels have made a big difference to my electricity bill, reducing it from £65 to £20 per month.”
For another resident, the savings have been even greater, with monthly electricity meter costs dropping by more than half:
“We were putting £198 a month on the electricity meter, now it’s as little as £80 a month, saving £120!”
Other households have reported their electricity bills halving, while one resident who previously spent around £6 to £7 per day on electricity has seen their average daily cost fall to approximately £1.40.
These are meaningful savings that residents can see in their household budgets straight away. Alongside reducing reliance on electricity purchased from the grid, Solar PV can give households greater control over their energy use at a time when the cost of living remains an important concern.
For Local Authorities and housing providers, this demonstrates the wider value of delivering Solar PV at scale. It is about turning investment in energy efficiency into real, measurable benefits for residents and their homes.
Solar PV Is Becoming a Bigger Part of the UK’s Energy Future
The latest installation figures demonstrate just how quickly attitudes towards domestic solar are changing.
For Local Authorities and housing providers, the opportunity is significant. Solar PV can form an important part of long-term strategies to reduce household energy costs, improve housing stock and accelerate progress towards wider sustainability objectives.
Westville Group is proud to be playing its part in that transition.
With extensive experience working across the social housing sector, established Solar PV capabilities and the capacity to deliver large and complex programmes as a Tier 1 contractor, we’re ready to support clients looking to take the next step with Solar PV.
