Announcement: Acquisition of NS-UK

Expanding Our Specification Consulting into the UK and Middle East

We are delighted to announce that Earlymark, a leading Australian specification consultancy, has acquired National Specifications UK, an established and respected specification consultancy based in England.

This marks an exciting new chapter for both organisations, and for the architectural practices we support.

Strengthening Specification Excellence Across Markets

Both companies share a common focus: Delivering high-quality, independent specification consulting services to architectural clients. By combining our expertise, we significantly enhance our ability to support architects across multiple regions and complex project environments.

Our UK clients will continue working with the same trusted team, now strengthened by Earlymark’s systems, technical capability, and innovation. Likewise, our Australian clients gain access to expanded international insight and experience.

Will Hamlyn-Harris, Director of Earlymark, said:

“This is an exciting step in bringing leading specification consultants together under one banner. We share a strong commitment to protecting and supporting architects to deliver better project outcomes. Expanding into the UK and Middle East allows us to strengthen that support while introducing new tools, systems, and capability to the market.

I have long regarded Steve as one of the UK’s foremost authorities in specification consulting, and the depth of expertise that Tai and the team bring to complex Middle East projects further strengthens our collective capability.”

Steve Walton, Director of National Specifications UK, added:

“From the get go, it just felt like the right fit, and we very much look forward to representing Earlymark here in the UK. Joining Earlymark gives our clients access to expanded technical resources and innovation, while maintaining the personalised service and independence they value. It represents a strong strategic alignment and an exciting step forward for our team and the practices we work with.”
