A call to allow a 600-acre Pembrokeshire potato farm to keep a holiday let erected “in innocence” without permission, which is said to be essential for supporting the business, has been approved.

In an application recommended for approval at the January 13 meeting of Pembrokeshire County council’s planning committee, Mr and Mrs I and F Elliot sought permission for the continued use of a mobile unit with a veranda as tourist accommodation at Cresswell Barn Farm, Cresswell Quay.

Cresswell Barn Farm supplies potatoes to Welsh supermarkets and the site has a certified campsite.

The application was before the committee rather than being delegated for an officer decision as it was recommended for approval, subject to the completion of a Section 106 legal agreement essentially keeping it for holiday use only, despite being in conflict with the development plan and was made by a close family member of an officer in the planning service.

An officer report accompanying the application said an enforcement investigation was started way back in 2012 following a claim a caravan was located at the site and was being used for residential purposes.

That was closed in 2023; a 2022 investigation taking place after an allegation a structure on-site was being used for holiday letting.

A 2023 certificate of lawfulness application was made to regularise the breach of planning, saying the unit had been used for residential purposes for more than a decade, but insufficient information was provided to allow it, the report said.

An appeal against this was later made to Planning and Environment Decisions Wales (PEDW) but was withdrawn by the applicant.

It said the enforcement action was ongoing, leading to the formal planning application.

Of the site itself, the report said: “The agent has confirmed that due to many variables, there is no typical year for the enterprise in terms of profitability and that the income generated from tourist related activities at the farm, is critical to the farming enterprise. The high-quality holiday unit therefore provides an additional income stream for the farming enterprise.”

It added: “The holiday unit is located adjacent to buildings that make up the farm complex, with the accommodation offering guests an immersive rural experience that introduces them to aspects of the rural economy.

“Information submitted in support of this application confirms that the income from the holiday uses at the site is critical to supplementing the potato farming enterprise.”

Speaking at the meeting, Fiona Elliot said the holiday let was a small-scale part of the wider farm complex; the building having been on-site for some 15 years, the applicants more recently “in innocence” using it as a holiday let, which visitors have described as “five-star,” not realising they needed planning permission.

Following a call by Cllr Brian Hall to back the officer recommendation of conditional approval, members unanimously supported that.
