Groundwork & Foundations- 24 Jul 2026
A great team you can trust. I’m a cautious customer, but they immediately put us at ease with their professionalism and obvious experience. We needed a concrete slab pumped into a long, narrow extension with access from one side only, and they managed the entire process smoothly from start to finish. The result was a perfectly level, high-quality slab. Thank you!

Carpentry- 5 Jan 2025
Aaron initially impressed me with his commitment and fair pricing, delivering and installing staircases well. However, when he offered to tile a bathroom, things went downhill. Instead of handling it himself or assigning someone he trusted, he brought in a tiler he’d never worked with before. The results were disastrous—uneven tiles, poor grout work, and an overall lack of quality. Aaron offered to fix some issues but didn’t supervise the work, leaving it to me. His repairs only made things worse. After the job was finished, he ignored my detailed list of tiling mistakes and stopped responding altogether. I had to hire another tiler to fix some issues, but many problems remain because further repairs were too costly. While Aaron is an eloquent speaker and seemed committed initially, his actions didn’t match his words. I cannot recommend him and caution others not to be swayed by small talk or promises without clear oversight and proven reliability.

Kitchen Fitting- 14 Jan 2026
My initial experience with Solis Power Limited was Leo’s immediate response within 30 minutes, visited my property to view my kitchen. He gave a full detailed breakdown of price list that explains each work to be carried out. Suggested materials to use also help with the purchase. Leo and his team are perfect working together, cleaned after themselves each day. They installed new electrical unit, also introduced registered gas man to run gas pipes and also connect the gas hob. Plumbing work was excellent too. Leo also helped with the measurements of splashback and splash splatter guard. The work was carried out within five working days delay was due to shortage of splashback in the store. I highly recommend Leo and his team.
