Summary of the contracting process

Pembrokeshire Coast National Park Authority is seeking consultant services to assess and prioritise nature-based interventions to improve water quality in the lower Western Cleddau, with other relevant catchments considered if feasible. The work is a research and environmental consultancy assignment (CPV 73210000). It will combine desk-based assessment and GIS analysis to identify and map pollution sources, pathways, receptors and priority reaches, with targeted walkovers to test findings on the ground. Stakeholder and landowner engagement will support access, feasibility and future implementation. Required outputs include an updateable GIS opportunity and prioritisation database, mapbook, narrative report, and selected case studies or scenarios. The assessment must distinguish strategic priorities from actionable opportunities and consider future nutrient mitigation or credit potential. Work is for the Authority in Pembrokeshire, Wales.

The procurement has reached tender: the Authority invited proposals through a below-threshold open competition. Enquiries were due by 9 October 2026 at 12:00, and tender submissions by 12 October 2026 at 17:00. The contract is scheduled to run from 1 November 2026 to 28 February 2027. Its estimated value is £38,000 excluding VAT, or £45,600 including VAT. There is one lot. Evaluation is based on quality and cost: understanding of the brief, risk, methodology, approach and delivery carries 45%; team, experience and capability 25%; cost and added value 20%; and project management and governance 10%. Electronic submission is allowed. The opportunity is identified as suitable for SMEs and voluntary, community or social enterprises.

This opportunity suits environmental and research consultancies able to combine water-quality assessment, nature-based solutions and practical catchment planning. Strong candidates will need GIS capability, including spatial analysis, mapping and development of an updateable prioritisation database, together with the ability to interpret pollution source, pathway and receptor linkages and hydrological connectivity. The brief also calls for targeted field walkovers, evidence-based identification of intervention opportunities, stakeholder and landowner engagement, and clear reporting through a mapbook, narrative report and case studies or scenarios. Relevant experience in water-quality improvement, catchment management, ecological or natural flood and nutrient mitigation work would be well aligned. Suppliers should also be able to distinguish strategic priorities from deliverable actions, assess implementation feasibility and explain potential future nutrient-credit opportunities.

Notice Information

Notice Title

Strategic nature-based water quality improvement assessment - Lower Western Cleddau / Asesiad strategol gwella ansawdd dwr yn seiliedig ar natur - Rhan Ifaf Cleddau Wen

Notice Description

Pembrokeshire Coast National Park Authority invites proposals from consultants to identify and prioritise nature-based intervention opportunities that could contribute to improving water quality in the lower Western Cleddau (and possibly other relevant catchments if feasible within the budget). A transparent, weighted multi-criteria approach will assess water quality benefit, source / pathway / receptor linkages, hydrological connectivity, intervention potential and implementation feasibility. GIS analysis will identify and map pollution sources, pathways, receptors and priority reaches using available datasets. Stakeholder and landowner engagement will support fieldwork access, inform feasibility and foster future implementation support. Targeted walkovers will ground-truth and refine the assessment, identifying opportunities and constraints not evident from desk-based information. Outputs will include an updateable GIS opportunity and prioritisation database, mapbook, narrative report and selected case studies / scenarios. The assessment should distinguish between strategic priorities and actionable opportunities and briefly consider future nutrient mitigation / credit potential of interventions (and how this might influence take-up). Budget: PS38,000 ex VAT, funded by Estee Lauder Companies UK & Ireland via the UK National Parks Foundation. Mae Awdurdod Parc Cenedlaethol Arfordir Penfro yn gwahodd cynigion gan ymgynghorwyr i nodi a blaenoriaethu cyfleoedd ymyrryd sy'n seiliedig ar natur a allai gyfrannu at wella ansawdd dwr yn rhan isaf Cleddau Wen (ac efallai dalgylchoedd perthnasol eraill os yw hynny'n ymarferol o fewn y gyllideb). Bydd dull tryloyw, wedi'i bwysoli, gyda nifer o feini prawf yn asesu mantais o ran ansawdd dwr, cysylltiadau tarddle / llwybr / derbynnydd, cysylltedd hydrolegol, posibilrwydd ymyrryd a dichonoldeb gweithredu. Bydd dadansoddiad GIS yn nodi ac yn mapio tarddleoedd, llwybrau, derbynyddion a rhannau blaenoriaeth llygredd gan ddefnyddio'r setiau data sydd ar gael. Bydd ymgysylltu a rhanddeiliaid a thirfeddianwyr yn cefnogi mynediad at waith maes, yn llywio dichonoldeb ac yn meithrin cymorth gweithredu yn y dyfodol. Bydd teithiau cerdded wedi'u targedu yn cadarnhau ac yn mireinio'r asesiad, gan nodi cyfleoedd a chyfyngiadau nad ydynt yn amlwg o wybodaeth desg. Bydd yr allbynnau'n cynnwys cronfa ddata blaenoriaethu a chyfleoedd GIS y gellir eu diweddaru, llyfr mapiau, adroddiad naratif ac astudiaethau achos / senarios dethol. Dylai'r asesiad wahaniaethu rhwng blaenoriaethau strategol a chyfleoedd y gellir eu rhoi ar waith ac ystyried yn gryno botensial ymyriadau i liniaru maethynnau / credydau yn y dyfodol (a sut y gallai hyn ddylanwadu ar y nifer sy'n manteisio arnynt). Cyllideb: PS38,000 heb gynnwys TAW, sy'n cael ei ariannu gan Estee Lauder Companies UK & Ireland drwy Sefydliad Parciau Cenedlaethol y DU.
