The Scottish bank is currently based out of Henry Duncan House, at 120 George Street in Edinburgh, which is listed by Historic Environment Scotland as a “high quality building which fits well into the streetscape despite the richness of its detailing”.

The sale of the headquarters comes just weeks after Spanish bank Santander confirmed a £2.65 billion cash deal to take over TSB Bank.

In August, shareholders of another Spanish banking group, Sabadell, voted to approve the sale, with the acquisition of TSB expected to be completed during the first three months of 2026.

Santander has said that it intends to “integrate TSB in the Santander UK group, enabling it to become the third largest bank in the country by personal current account balances”.

CBRE, the commercial real estate firm, has listed the TSB headquarters on its website, saying: “Situated behind a traditional façade, the office space is spread over the lower ground to 4th floors around a central and impressive atrium which also at ground level provides communal break out, meeting and café space.

“Glazed lifts provide access to all floors. Staff amenities including showers, lockers, car parking and bike racks are located at lower ground floor level.”

It goes on: “The office is located in the heart of Edinburgh’s City Centre at the Western end of George Street.

“The location is unrivalled in terms of public transport via bus stops and routes, tram stops and situated midway between Edinburgh’s two largest rail stations, Haymarket and Waverley.

“George Street is renowned for its independent and boutique shops, with an abundance of restaurants, cafes and coffee shops supplemented by a range of hotels and bars.”

Daily Business reported that agents believe the building is currently let at an “exceptionally low rate” of £25.12 per square foot.

TSB Bank has a lease for Henry Duncan House until December 2031, reports say.

George Street runs parallel to Prince Street in the centre of Edinburgh.
