During the year ending December 2015, Medlock saw turnover hit £25m, up from £18.54m the previous year.
The soaring revenues are a result of a number of high profiled contract wins throughout the year with some of the UK’s leading brands.
This saw Medlock securing work with the likes of Casual Dining Group, Thai Leisure Group, Mitchells & Butlers, Empire Cinemas and Langdale Leisure.
Medlock also enjoyed strong repeat business with major customers such as Premier Inn, Enterprise Inns, Greene King, JD Wetherspoon and Joseph Holt.
Finance director Colin Drury said: “We are pleased to report that the company has achieved record sales and further progress against our business plan and strategy of continued long-term growth.
“Repeat business with our major customers has been a tremendous success, accounting for 68 per cent of the sales total, while our customer base has been strengthened with the addition of further premium brands.
“We have added key staff in the project delivery process, enabling us to deliver our projects safely, on time, to budget and to the highest quality, leading to further repeat business.
“We will continue to work hard to drive value while consistently delivering customer service and quality across the business.”
The firm, which has its headquarters in Oldham and operates nationwide, is on track for further strong growth this year.
Revenues in the first three months of 2016 climbed 14% compared with the same period last year, from £5.5m to £6.3m.
