Although reputed to have a history going back as far as 1625, Hotel Mariners in Haverfordwest has been more reliably dated to 1729 - heyday of the Georgian coaching Inn.

Whatever its true age, this comfortable, well-appointed Grade II listed property in the town centre has remained the principal hotel in Haverfordwest and is now on the market with Colliers International with offers invited in the region of £1 million.

Peter Brunt, a director in Colliers International’s Hotels Agency team, said Hotel Mariners had been in the same family for three generations, but younger members of the family are looking to other careers so the hotel is on the market for the first time since 1981.

“This gives potential operators an opportunity to purchase a fully functioning business in this key regional town,” he said.

“Hotel Mariners is a real all-rounder, serving both locals and visitors and is frequently used for weddings and other functions.”

“Haverfordwest is at the hub of a lovely corner of Pembrokeshire and provides a great base for prospective owners.  In addition to being a great place to live and work, the accounts for year ending October 2017 show net sales of £707,382 which resulted in a tidy profit.”

The landmark hotel has 27 letting bedrooms and, crucially for this part of Pembrokeshire, a large car park, although it also benefits from being within walking distance of local shops, supermarkets and leisure facilities.

The main hotel was constructed in the 18th century with alterations in the 20th Century – more recently the lounge bar has been fully refurbished and caters for around 45 people. The restaurant is arranged over two floors with 64 covers. In addition, there is a first floor, theatre-style conference room.

Peter Brunt said: “The former meeting room is presently used as a ladies clothing shop – on sale, a six month lease will be granted to allow this use to continue until an alternative venue is found.

“Next door to the hotel is a three-bedroom house with a common boundary, which is available by separate negotiation. This property is not currently used as part of the business but could be used as an owners’ home or for staff accommodation.”

He added: “Haverfordwest is the ancient county town of Pembrokeshire and acts as a hub for people to explore the surrounding region, with good connections to Fishguard, Cardigan, Milford Haven, Narberth, Carmarthen and Tenby.

“The town is just six miles from the Pembrokeshire Coast National Park - the UK’s only coastal National Park - which attracts many thousands of tourists every year.”
