Solar PV | Battery Storage | Asset Management
Your future starts here.
A team that trains, qualifies and promotes from within
Sustain UK Holdings is a group of operating companies spanning residential and commercial solar, battery storage, operations and maintenance, and community energy. When you join us, you join a group with a pipeline of work - not a single project.
Every Qualification Funded
Apprenticeship training, college day-release, ECS assessments and industry accreditation are paid for by us. You earn while you learn.
Real Progression
Our apprentices become improvers, improvers become installation engineers, engineers become team leaders and surveyors. Your pathway is mapped from day one.
Work That Matters
Community energy schemes, school and council rooftops, and the UK's largest residential battery rollout. The work you do cuts bills and carbon for real communities.
Modern Equipment
Quality tooling, branded vans, proper PPE and the latest battery and monitoring platforms - we do not cut corners on kit or safety.
Mentors, Not Just Managers
Every apprentice and graduate is paired with an experienced engineer. Toolbox talks, structured reviews and time built into the programme to pass assessments.
Stability & Scale
Multi-year rollouts and framework agreements mean stable work, predictable programmes and a future you can plan a mortgage around.
Apprenticeships & trainee pathways
We are a JIB-registered company working with local FE colleges and the National Electrotechnical Training (NET) programme. Our structured entry routes are open to school leavers, career changers and people returning to work.

Everyone at Sustain - from apprentice to director - works to a competency matrix with structured training, ongoing CPD and funded accreditation. It is how we keep quality high, sites safe and customers happy.
