Sustainable Workplace finalists revealed for Clean and Green Awards 2026
These organisations have been recognised for putting sustainability practices into their daily operations.
Delta Fire is a UK-based manufacturer of frontline firefighting equipment, supplying most of the UK’s Fire & Rescue Services and the entirety of the Royal Navy with fire nozzles, alongside growing international markets across Europe and the Middle East.
Founded more than 35 years ago, Delta remains family-owned and headquartered in Norwich, Norfolk, operating from a new £5.5m sustainable facility at Broadland Business Park.
The company’s new manufacturing site operates on 100% renewable electricity, supported by a 300kWh solar battery storage system, EV fleet transition and a zero-to-landfill waste policy.
The judges said: “The mindset of minimising waste (right from the design team to everywhere else across the business) really shows environmental impact to be at the heart of the business operation.”
They also said the innovative repurposing of products to give them a second life is exemplary.
Harwich Haven Authority
Established in 1863, Harwich Haven Authority (HHA) in Essex is one of the UK’s largest trust ports, providing navigational services and pilotage to the world’s largest and deepest vessels.
Its jurisdiction stretches over 150 square miles, encompassing the estuary, the Rivers Orwell and Stour, and land and assets across Essex and Suffolk.

In 2023, HHA launched its Environment, Social and Governance (ESG) Strategy to reinforce and formalise its commitment to protecting the local environment and support local communities. It works to embed sustainability across its operations every day.
The judges said: “We noted significant improvement year-on-year, with a real increased focus on community, social value and employee engagement.”
They also praised HHA’s transfer of knowledge internationally.
Mercury Theatre, Colchester
The Mercury Theatre in Colchester, Essex, has made great strides in incorporating sustainability practices into its operations, with a strong focus on environmental responsibility and community engagement.
It operates on 100% renewable electricity and the building management system optimises lighting, heating and ventilation to reduce energy use.
The venue ensures as much waste as possible is recycled.
As part of its commitment to sustainability, the Mercury Theatre has native trees and vegetation on the grounds.
The judges said that the focus on sustainability at the Mercury comes from the CEO downwards.
They added: “The theatre demonstrates a real underlying desire to ensure it adopts sustainable business practices to keep it operating for decades to come.”
