The firm, which was established in 1983 with a small office in Kelso and on Berwick-upon-Tweed’s quayside by accountant Andrew Douglas Home, now employs 70 staff across seven offices in Scotland and England.

The company attributes its growth to a proactive approach, utilisation of the latest technologies, and strong client relationships.

Current Douglas Home & Co managing director, Darren Thomson, said: “It’s incredible to see the growth of the firm since Andrew started the business in 1983.

“Forty years advising some incredible businesses and individual clients across Scotland and England is a significant milestone and we are looking forward to the next 40 years and beyond of the same.

“Being ahead of the curve has really helped that growth and making the best use of latest technologies to be as efficient and cost effective as possible for our clients was an important chapter for us. We first invested in computers back in 1989 when they each cost around the price of a new car.

“On top of that, major investment in tech has been crucial in providing complex advice to clients who themselves are adapting their business models to meet present-day challenges.”

Following the retirement of founder Mr Douglas Home in 2003, the practice has been in the hands of Alan Drummond, who led the team of directors for several years, and who chose to strengthen the board with the appointment of Mr Thomson, Mike Johnston, Caroline Tice, Sheryl Macaulay, and Victoria Ivinson.

The firm’s success can be measured not only in longevity but in the consistent growth of annual turnover — increasing from around £200,000 in the early 1990s to £1 million by 2010 and exceeding the £4 million mark at the turn of this decade.

Mr Thomson added: “Financial success and security is important for any business, but we also pride ourselves on the strength of our client relationships, with a good number dating back to the founding of the firm.

“We have also been very focused on investing in staff and improving individual’s professional and commercial know-how to create teams which match the growth in the size of our business and meet clients’ expectations.

“It has been some journey over the past 40 years and it has been incredible to watch Douglas Home & Co adapt and thrive in the ever-changing industry — we can’t wait to see what the next 40 bring.”
