Helensburgh's new waterfront swimming pool and leisure centre will be built by a firm from Northern Ireland - Heron Brothers Ltd.

Announcing news of the contract award on Thursday, Argyll and Bute Council also revealed that the cost of the project has jumped again – from £19.5 million to £22 million.

The contract will also deliver strengthened flood defences, altered car parking arrangements, and improved public meeting space for residents and visitors.

The contract award was finalised by councillors at two meetings last month, but a 'standstill' period in the regulations on the award of major contracts meant that the identity of the winning bidder – and the value of the contract – could not be revealed until July 15 at the earliest.

The 'contract mobilisation period' starts today (Thursday), with work on the site due to start in August.

The new leisure centre is scheduled to open to the public in August 2022, after which the existing swimming pool will be demolished and work will start on the new car parking facilities.

Based in Draperstown, north-west of Belfast, Heron Brothers Ltd was established in 1956 and also has offices in Glasgow, Manchester and London.

Helensburgh councillor Gary Mulvaney, Argyll and Bute's depute leader and the authority's policy lead for finance and major projects, said: “The appointment of Heron Brothers Ltd marks one of the most significant milestones of this complex project.

"The award of this contract is the culmination of years of planning, engagement, consultation and due diligence.

"As we emerge from Covid-19 and its global impact, contracts and projects such as the waterfront development will play an essential part in helping our regional and national economies to recover.

"As work starts in August, our local economy will benefit from employment and service opportunities.

"It’s a really exciting time for Helensburgh that will not only provide residents with a fantastic facility but also provide a positive draw for visitors and people thinking about moving to the area.”

Cathal Heron, regional director for Heron Brothers Ltd, said: “Heron Brothers Ltd are delighted to collaborate with Argyll and Bute Council and their team to construct the Helensburgh waterfront project for the area.

"The new leisure centre will continue to enhance our considerable experience in the sports and leisure sector and we are looking forward to starting on site and delivering a first class facility for the people of Helensburgh.”
