Edinburgh Airport’s £500m expansion programme gathers pace

Edinburgh Airport is pressing ahead with a £500 million expansion programme that will increase its terminal footprint by 60% and reshape key parts of the airport over the next five years.

The programme is the biggest capital investment in the airport’s history. Plans include new gates, extra departure space, expanded baggage and arrivals facilities, more retail and food-and-drink space, and changes to the airport forecourt and entrance areas.

South East Pier project is a major early phase

One of the most visible parts of the programme is the South East Pier extension, which is being delivered by Balfour Beatty under a contract worth about £65 million.

The two-storey extension will add eight departure gates and create more space for passengers, along with new seating areas and operational facilities. Recent works have also included the installation of eight link bridges in a live airport environment.

That pier project is due to be completed in summer 2027 and forms part of the first phase of the wider investment plan.

Wider expansion goes beyond the pier

Edinburgh Airport’s own development plans show the scale of the wider programme.

The airport plans a 4,000m² departure lounge expansion, creating more space for passengers, plus a new food-and-drink hub, extra seating, and improved boarding areas.

A 2,400m² baggage hall expansion is also planned to improve baggage handling capacity, while a separate project will expand the international arrivals and baggage reclaim area.

The airport is also proposing a major forecourt and plaza expansion, including a new terminal entrance, more space for passenger flow, extra retail provision and changes to security and check-in areas over multiple phases.

What it means for Scottish businesses

For Scottish businesses, the programme matters beyond aviation.

At one level, it’s a major infrastructure and construction pipeline involving contractors, subcontractors, suppliers and specialist partners. On another level, it’s a long-term investment in one of Scotland’s most important transport assets.

Improved airport capacity and passenger flow can support tourism, trade, business travel and inward investment, while also creating future opportunities across retail, food and drink, services and operations linked to the airport estate.

The airport has said the full programme is intended to create a more modern and future-proof gateway for Scotland as passenger demand continues to grow.

Record passenger numbers help explain the scale

The investment follows a record year for Edinburgh Airport, which handled almost 17 million passengers in 2025.

That growth helps explain the scale of the current programme. The airport isn’t simply making cosmetic changes. It’s expanding infrastructure across gates, baggage, arrivals and front-of-house areas to support higher passenger volumes over the longer term.

For ScottishBusiness.com readers, it’s the kind of development worth watching not only as a transport story, but as a broader signal of business confidence, construction activity and future commercial opportunity in and around Edinburgh.
