“Particularly thorough and forensic in his approach, he is highly focused, diligent, confident and concise, and gets right to the heart of the issues.” The Legal 500 2022

Juan is a well-established practitioner in all planning and major infrastructure disciplines (especially energy and transportation development consent orders (DCOs) and Transport and Works Act Orders (TWAOs), housing and regeneration, and iconic schemes, which is complimented by his work in compulsory purchase (acquisition) and compensation (encompassing wayleaves, road and rail infrastructure, land valuation and trespass), highways and rights of way.

Juan is a leading environmental, energy and natural resources practitioner, comprising consenting and enforcement, waste (including shipments and international disposals), contaminated land, climate change, coastal and marine defence, environmental impact assessments (EIA)/SEA (Strategic Environmental Assessment), habitats, water, air quality, nuisance, agriculture and sustainability.

Juan’s energy regulatory and disputes practice incorporates the breadth of the energy supply and distribution network infrastructure, code rights, infrastructure wayleave agreements as well as regulation and licensing under the Gas and Electricity Acts, before tribunals and in arbitration and ad hoc mediation.

Juan’s construction and property (commercial) disputes practice typically includes high value construction defects, surety liability, asbestos, estate contracts, overage, and options, with experience across domestic and international jurisdictions (EU, Southeast Asia, UAE) before the Technology and Construction Court (TCC) and Chancery Division, and in arbitration.

Juan also advises on heavyweight environmental and land tax liabilities, including landfill tax (loss on ignition (LOI) sampling, temporary infrastructure, quarry exemptions and organic waste) and the UK Climate Change Levy and CRC Energy Efficiency Scheme.
