Solar PV and LED Installation and Roof Repairs

Our programme took place at four schools in the London Borough of Hounslow. Works included the installation of roof-mounted Solar PV systems, LED lighting upgrades, electrical infrastructure improvements, connection works and roof repairs.

What we did

Axis delivered a Solar PV, LED and Roof Repairs programme for the London Borough of Hounslow.

Specifications

Roof-mounted solar photovoltaic (PV) systems ranging from 35kWp to 49kWp
Energy-efficient LED lighting
Associated electrical infrastructure and connection works
Testing, commissioning and handover of all systems
Roof repairs
Value-engineering identified additional energy savings
Legacy educational and learning programme

The London Borough of Hounslow appointed Axis following a successful mini competition through the LHC Retrofit and Decarbonisation (N9) framework under Workstream 6 – Solar PV and Electrical.

Funding for the programme was secured through a combination of grant funding from the Greater London Authority and the Department for Energy Security and Net Zero for the solar PV installations and direct council investment for the LED lighting.

And so we worked closely with school leadership teams and the council’s project management team to coordinate access, maintain safeguarding standards and ensure works were completed safely around pupils and staff.

We scheduled the majority of installation activity during school holidays and half-term breaks, reducing disruption to teaching and learning.

And our electrical specialists and roofing teams worked simultaneously across multiple sites. This enabled efficient delivery, with some installations completed within a single week while maintaining quality and programme deadlines.

Axis also worked collaboratively with the London Borough of Hounslow’s project management team to identify additional opportunities for LED lighting improvements beyond the original scope. These value-engineering opportunities created further energy savings and enhanced the long-term benefits of the programme.

As part of our social value commitment, Axis is supporting each school with a £1,000 environmental donation to fund sustainability initiatives, educational resources and activities selected by the schools. We also committed to delivering educational presentations to pupils, helping them understand renewable energy, sustainability and carbon reduction.

Challenges and Solutions

Working within operational school environments required careful planning, excellent communication, collaboration and flexibility.

I’m so pleased working with Axis on this project. The team are absolutely fantastic. They are phenomenally efficient. They’ve come into the schools over half term, changed nearly 2,000 light bulbs, installed solar panels on the roofs, all while the children were on holiday. Isn’t that amazing?

These kids are going to learn in an environment that prizes the environment. They’re going to learn about saving their planet through the projects that are right here on their doorstep, and that creates climate-conscious citizens from day one – Councillor Salman Shaheen
