A caravan park’s call on the outskirts of Tenby to be allowed to keep site works completed without permission nearly a decade ago has been given the thumbs-up by the National Park.

In an application to the Pembrokeshire Coast National Park Authority, Richard Shannon, through agent Gerald Blain Associates Ltd, sought permission for a certificate of lawfulness for the retrospective siting of a waste treatment plant for the Windmills Caravan Park, Narberth Road, Tenby.

An application for a certificate of lawfulness allows an applicant to stay at or keep a development if they can provide proof of occupancy or use over a prolonged period.

A supporting statement accompanying the application said the plant was installed back in summer 2018, providing a receipt of purchase and an invoice for the installation works, 2018 Aerial imagery showing ground disturbance in the location where the tank is installed as well as other photographic evidence.

“Together, this evidence clearly demonstrates that the development was carried out and substantially completed in 2018 and has remained in situ since that date,” the statement said.

An officer report recommending the certificate of lawfulness be granted said Windmills Caravan Park is an established holiday caravan park located on Old Narberth Road, approximately two kilometres north of Tenby, occupying a sizeable rural site with static caravans, internal access roads, ancillary infrastructure and areas of open grassland.

Of the certificate call, it said: “The application relates to a package sewage treatment plant located within the south-eastern corner of the caravan park, adjacent to an established hedgerow and mature tree belt.

“The treatment plant is predominantly underground, with only limited above-ground features visible, including inspection chambers, ventilation equipment and associated control apparatus. The location was selected to serve the existing caravan park whilst remaining discreetly positioned within the wider site and benefiting from natural screening provided by the surrounding vegetation.”

In respect of the submitted information accompanying the application, it said: “As the application was submitted in 2026, the development has been in place for well in excess of the four-year enforcement period and is therefore immune from enforcement action. Accordingly, the Local Planning Authority is satisfied that the development is lawful for the purposes of Section 191 of the Act, and a Certificate of Lawfulness should be issued.”
