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.
