Frequently Asked Questions (FAQ)
How do I know which renewable system is right for my property?
It depends on your building type, energy use, and available space. Our specialists carry out a full energy audit before recommending the best combination—solar panels, heat pumps, EV charging, and smart controls.
Can I combine solar panels with a heat pump or EV charger?
Yes. Many clients integrate multiple systems for maximum efficiency. We can design a complete smart energy setup where solar helps power your heating and vehicle charging.
How much can I save by switching to renewable energy?
Savings vary by system size and usage, but households commonly reduce electricity bills by 40–70%. Commercial sites often achieve ROI in 3–6 years through lower energy costs and available incentives.
Do you help with grants or government funding?
Yes. We guide you through current UK schemes (e.g., Boiler Upgrade Scheme, ECO4) and handle the paperwork where applicable.
Will I need planning permission for solar panels or heat pumps?
In most residential cases these are permitted development. Listed buildings, conservation areas, and flats may require permission—we’ll assess and manage applications if needed.
What certifications do your engineers hold?
Installations are completed by MCS-certified engineers, compliant with Part L energy efficiency standards. We also work to PAS 2035 retrofit principles on relevant projects.
How often should renewable systems be serviced?
We recommend an annual service to keep panels, heat pumps, and chargers safe and efficient. Maintenance plans are available for homes and commercial sites.
Can you upgrade an existing energy system?
Yes. We can audit, upgrade, or integrate new technologies with your existing setup for higher performance and real-time monitoring.
Do you handle both residential and commercial installations?
Absolutely. We deliver solutions for homes, offices, retail, and developments of all sizes across London.
How soon can installation begin after approval?
Most projects begin within 2–4 weeks, subject to equipment lead times and site conditions.
