Environmental and sustainability obligations now shape how organisations plan, invest and operate. Decarbonisation targets, climate risk and evolving Environmental, Social and Governance (ESG) regulation increasingly determine whether projects are fundable, deliverable and resilient over the long term. If you are making decisions around development, regeneration, asset management or procurement, environmental law is rarely a discrete issue; it cuts across governance, funding, contracts and delivery.
Devonshires’ environmental and sustainability team advises clients at these critical decision points. We help you move forward with confidence by translating complex regulation into clear, practical steps that support delivery while managing risk. Our advice is grounded in how projects actually work, supporting you from early strategy and planning through procurement, construction, operation and long-term stewardship.
Environmental law at Devonshires is deliberately integrated. Our environmental lawyers work alongside planning, real estate, construction, corporate, finance and governance specialists, ensuring advice reflects the commercial, operational and public law realities you face. This approach is particularly valuable where environmental compliance intersects with funding conditions, procurement rules, landlord and tenant relationships or public sector decision-making
As an established environmental law firm with long-standing expertise in the built environment and public sector, we regularly advise on environmental compliance, ESG governance, biodiversity obligations and net zero strategies. If you need an experienced environmental compliance lawyer to manage immediate regulatory exposure, or strategic support from environmental solicitors to plan ahead, our focus is on keeping matters moving and decisions defensible.
Our environmental and sustainability practice supports developers, registered providers, local authorities, investors and commercial occupiers across advisory, transactional and contentious matters. If you are planning, delivering or operating assets in a tightening regulatory environment, we can help you understand what is required and how best to implement it.
We advise on:
Our environmental solicitors focus on implementation as well as compliance. We advise not only on what the law requires, but on how obligations can be delivered within existing operational, funding and contractual constraints.
We advise landowners on using their land to deliver biodiversity enhancements, including structuring section 106 planning obligations and conservation covenants to enable the sale of units for Biodiversity Net Gain. This work requires careful alignment of planning, environmental and property law to ensure schemes are practical, fundable and legally robust.
We have advised Metropolitan on the Clapham Park Regeneration Project in the London Borough of Lambeth. Our role includes negotiating and reporting on a new section 106 agreement linked to what is understood to be the largest detailed planning application in the country, alongside deeds of variation to existing section 106 agreements. We have also advised on third-party licences, highways agreements, utilities arrangements (including leases, licences, wayleaves and statutory agreements), rights to light matters, compulsory purchase order issues, and energy and ESCO-related leases, together with wider property due diligence.
This experience allows our environmental lawyers to anticipate regulatory and delivery issues early, helping you make informed decisions before they become constraints.
Our environmental and sustainability practice is led by Partners Hannah Langford, Kris Kelliher and Jamie Leonard, each with extensive experience advising on planning, environmental and infrastructure-related matters. They remain closely involved throughout matters, supported by a wider team with deep sector knowledge.
You will work with senior environmental solicitors who take the time to understand your objectives, risk appetite and delivery pressures. This enables us to provide advice that is technically robust, commercially grounded and responsive to the realities you face.
If you are navigating environmental regulation, sustainability obligations or decarbonisation requirements, our environmental lawyers can help you decide what to do next and how to proceed with confidence.
