About Eres Group
Solar and energy asset specialists, London, Essex, & the South East
Eres Group is a specialist solar PV and energy services company supporting residential, commercial and public-sector energy assets throughout their operational life. Trading since 2019 and based in Essex, we design and install solar PV, and we service, maintain and report on systems for housing associations, local authorities, managing agents, businesses and homeowners across London and the South East. The same processes now run our Australian operation in Sydney.
We work with housing providers, public bodies, commercial and residential clients to deliver:
ERES Group is focused on keeping energy assets performing safely, efficiently and reliably over time.
We work with commercial and industrial clients to deliver:
- Design and installation of solar PV and battery storage (MCS-certified)
- Condition reports and compliance documentation for landlords and asset owners
- Planned and reactive service and maintenance
- Asset management and performance optimisation
- System monitoring and reporting
- Electrical and wider energy infrastructure support
- Long-term maintenance programs aligned to operational requirements
Our role goes beyond fixing faults. We help clients maintain visibility and control over their assets, reduce unexpected downtime and ensure systems continue to perform as intended year after year.
Established in the UK
ERES Group was established in the UK to meet a growing need for professional, transparent and accountable energy services. Over time, we’ve refined the way we operate, developing structured maintenance frameworks, clear reporting standards and disciplined delivery methods suited to complex commercial environments.
Every job – from a single-panel clean to a 100-property programme – runs on the same documented method:
- Structured, repeatable maintenance methodologies
- Clear documentation and reporting
- Consistent delivery standards
- A strong focus on safety, compliance and reliability
This foundation allows us to support clients where performance, uptime and risk management are critical.
Why Maintenance Matters Now
The UK Government’s Solar Roadmap (July 2025) targets 45-47 GW of installed solar by 2030, nearly trebling today’s capacity, as part of the Clean Power 2030 mission.
As that capacity grows, the focus has to move beyond installation to how systems are looked after. Distributed generation on homes, schools, housing estates and commercial roofs only delivers its intended value if it is monitored, maintained and reported on properly over 20-25 years. Without a structured service and maintenance framework, even well-designed systems underperform, introduce risk or fail to deliver their expected return.
UK Government target for installed solar by 2030, up from around 18 GW today (Solar Roadmap, July 2025).
What that means for asset owners
- Thousands of systems installed under FIT and SEG are now 5-15 years old and need structured maintenance
- Landlords and housing providers need documented evidence that systems are safe and performing
- Warranty and insurance conditions increasingly require periodic inspection
- Performance losses of 10-25% from soiling and faults go unnoticed without monitoring and reporting
Our Approach
Strong outcomes come from strong processes. At ERES Group, our approach is built on:
- Clear, consistent communication
- Transparent reporting and documentation
- Structured service and maintenance programs
- Proactive identification of issues
- Long-term partnerships, not one-off transactions
This gives our clients confidence and clarity — especially in environments where reliability and operational continuity matter.
Now Operating in Australia
Eres Group Australia, based in Sydney, delivers the same service and reporting standards for clients across New South Wales.
