What customers say

Based on genuine customer reviews

Photovoltaic systems, battery storage and electric vehicle charging sit at the heart of the work described by customers of this south London renewable energy specialist. Several reviewers explain that they collected quotes from other firms before committing, and something that features in review after review is how thorough the assessment was, including a roof inspection before any figure was offered and clear advice on which panels and batteries suited the property. Detailed quotations and patient answers to questions are mentioned repeatedly, alongside reliable timekeeping and a calm response when a delay caused by another trade pushed the work back.

Paul and Chris appear by name in many accounts, credited with genuine expertise and with guidance on tariffs and aftercare once the job was done, while electrician Dan is noted for tidy wiring. Installations covering sixteen panels, batteries and a charger are described as finished inside a single day, with commercial premises also completed. Courteous site teams, minimal mess and a high standard of finish recur, as does the system continuing to perform well long after handover, with the team monitoring output to keep it running as it did on the first day.

Absolutely brilliant service from SW3 Green Energy Services Ltd. They installed solar at our commercial premises and were efficient, well‑priced, and incredibly professional throughout.

Great experience from start to finish. The ONLY company who came to inspect our roof before quoting. Took time to explain which panels/batteries would be best for our set up. Smooth installation with polite and courteous workers. Great after sales advice and guidance towards tariffs etc. So pleased we bit the bullet and went with SW3.

Really pleased with SW3. Chris was great to deal with – understands what customers need and is easy to reach on WhatsApp. Yes, they’re busy, but whenever I had questions or minor teething issues he responded quickly and got things sorted. Installation was punctual, tidy and professional. One cracked panel on arrival was spotted immediately and replaced without fuss. Nick the electrician was excellent – neat, efficient and knows his stuff. Six months on the system is performing as expected. Overall, a very positive experience and I’d happily recommend SW3.

SW3 were extremely helpful throughout the entire process. The installation of the solar panels was explained to us very clearly, and we were given options regarding the placement of the battery and a full explanation of what to expect on the day of installation. On the installation day, two teams attended—roofers and an electrician. They worked efficiently, cleaned up thoroughly, and removed all rubbish. The electrician also gave us valuable advice on how to use the solar panels and battery, as well as how to operate the app to manage the system. Paul, the owner of the company, was always available and ready to assist whenever needed. Overall, a great job.
