    Brief

    Defra is seeking a supplier with strong scientific, technical and analytical expertise to operate the UK National Focal Centre (NFC), which models and maps the impacts of air pollution on UK habitats. The successful contractor will deliver annual UK-wide modelling and mapping of pollutant deposition including ammonia, nitrogen oxides and sulphur dioxide, assessing these against critical environmental load thresholds for acidity and nitrogen. They will also map ammonia concentration levels and evaluate compliance with critical concentration limits. Results will be reported at multiple scales: UK-wide with country breakdowns, plus detailed assessments for specific habitat types, Special Areas for Conservation (SACs), Special Protection Areas (SPAs), and Areas/Sites of Special Scientific Interest (A/SSSIs). The modelled data supports annual environmental reporting, evidence generation for policy decisions, biodiversity protection, and fulfils the UK's domestic and international environmental reporting obligations. The contract will commence 1 June 2027 with a one-month handover period (1-30 June 2027) before full responsibility transfers on 1 July 2027. Estimated contract value: £680,000 - £720,000.
