MJS Contracts Ltd was established in 2019 and is now a trusted business in the museum heritage as well as interior fit-out sectors. In the last five years, we have successfully completed many high-value and prestigious projects but, more importantly, we have managed to bring together a group of highly skilled and experienced individuals who understand the complexities involved in every phase of construction and fit-out projects.

In recent years, we have expanded our service catalogue from being a labour-only installation specialist to becoming a fit-out contractor delivering projects from RIBA Stage 4 onwards.

We undertake client direct contracts but also collaborate with the biggest UK fit-out companies. Regardless of project size and value, we take time to understand clients’ needs and requirements to ensure we allocate the right resources and provide the best possible service.

From project planning & estimating, through manufacture & coordination to on-site build & installation – we have the experience and expertise to deliver your projects efficiently, with a passion and understanding that every project is unique



Over the years, MJS has built a strong team of professionals, experienced and qualified to provide comprehensive services across all project phases – from technical design to on-site delivery.

At the heart of our joinery-driven company, we have a stable of talented bench joiners, reinforced by knowledgeable site managers, trained and skilled site installation teams and competent project managers. We carefully select our teams based on the project criteria to ensure they are executed successfully and to the highest quality standards.

We regularly collaborate with other experienced and credible trades, suppliers and contractors such as M&E, AVH contractors, display case fabricators, graphic producers, specialist fixers & decorators, which enables us to provide comprehensive services to our clients across the UK.




At MJS Contracts, we believe that every project is an opportunity to create something remarkable. We are driven by a set of core values that guide our work and define who we are as a company.
