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.

Extensions- 6 Aug 2022
Majid has been great in producing drawings for our rear extension. He's also helped explain the whole build process to us from design, building inspection, and building. We received our drawings in under 10 days from the initial consultation and site visit. Majid was accomodating and was able to visit the site on weekends for the initial consultation. Always a pleasure to deal with and has been easy to reach over the phone or email. Would highly recommend Maji and MYD Studio London to anyone looking for an architect.
