About Us

Subadra was formed during 1993 as a geo-environmental consultancy to the contaminated land sector. We are now one of the leading UK environmental consultancies in the UK and have a client base that extends from major oil companies to property developers, airports to supermarkets and from regulators to main works contractors.

We have always strived to be an extremely ‘hands on’ company and offer several unique advantages when it comes to the level of support we can offer to our clients. Our key advantage comes from the ability to complete the vast majority of our assessment works in-house.

Our flexibility means that we are able to deal equally well with incident response issues, construction waste classification issues, negotiation of the discharge of planning conditions, or completion of multi-site portfolios of work. 

We have excellent relationships with the majority of the main Principal Contractors (who value our rapid turnaround and support) and Regulators across the UK. We have repeatedly demonstrated our ability to successfully advise our clients on multi-site disposal portfolios.

We pride ourselves on rapid response, industry expertise, and strong relationships with principal contractors and regulators. Our track record includes advising on major multi-site disposal portfolios and delivering over £1m in remediation projects at petrol stations and fuel depots in the last five years.

Our main strength is the ability to respond rapidly to a Client’s needs. Our senior leadership team has over 100 years of combined industry experience. We understand the process and thrive in the most complex of environments.
