A Start to Finish Approach

We supply a diverse range of companies within the commercial sector. Regularly partnering with Local Authorities, RSL’s, housing (both mid and low rise), education, commercial bedspace and care & health organisations. Working together with these clients we have helped to build housing, schools, care homes, hotels and student accommodation. 

With a highly skilled team totalling over 75 years worth of experience, we have a strong understanding of the requirements in the commercial market. Our dedicated commercial team provide a start to finish approach, from specification, working with our design team to help optimise specifications whilst minimising installation costs through to onsite project management and working with developers and contractors to ensure completion on time.

We don’t just sell you what we want to make we work with you to understand your requirements, design intent, client needs, compliance, timescales and budget. Sash UK will then tailor our solutions to meet those needs.

Working across various sectors, we understand how to satisfy the exacting requirements of planners, meeting specification and performance requirements. This makes the process run smoothly, eliminating unnecessary delays.

We provide the option for supply only or you can take advantage of our supply and fit service working with our trusted installation partners.

Our products carry a plethora of accreditations, some standard and others optional, according to your projects needs, as well as compliance with certain requirements.

We get involved at design stage because It’s a well-known fact that there’s an opportunity to save up to 20% of costs at the design stage. The opportunity reduces to <5% at tender stage.
