Extensions- 11 Apr 2024
AMAZING CONTRACTORS ! Mali Constructions did an absolutely amazing job. They were professional and vey friendly. The works took 3 weeks and Mali ensured the works were carried out with high expertise. Such a smooth and great service and worthy every penny. The pricing was reasonable and within my budget and I was kept informed throughout the whole process. The project was completed to a great standard and we are very happy with our new space and would absolutely recommend Mali Construction to anyone looking to complete work. If you are looking for a contractor with great communication, great workmanship and priced correctly, I would definitely use Mali Construction Ltd. Mali would provide regular updates, discussions and even worked with my many changes to the plans during the process with no issues. No matter time or day, they were always on hand to respond to any questions. They were also quick to point out unnecessary extras that ended up saving us money.

Restoration & Refurbishment- 27 Aug 2026
Charlie and his team took two rooms back to brick and rebuilt them from scratch: new floor, plastering, ceiling and coving. Fantastic job throughout. Great workmanship, good communication, and they kept the site clean and tidy. They started promptly on the day agreed and finished within the timeline they’d quoted. Would happily recommend them and hope to use them again on future projects. Thank you!

We have worked with Alex and his team at Swift Conversions Ltd twice now—first for a house extension and then for a loft conversion and general refurbishment —and we wouldn’t hesitate to choose them again for our next project. From the moment we received the quote to the final completion, Alex was incredibly communicative, reliable, and always had a can-do attitude. Despite the challenges of fluctuating prices in the market, he delivered the project within budget and stayed true to his word. His professionalism and trustworthiness are second to none.
