A string of contract wins have boosted revenue at the Liverpool based business which also has offices in Manchester and London.
During the 2018/19 financial year Simm delivered projects including Media City Tower Two and Clippers Quay in the North West, as well as handing over sectional completion on its largest ever job at Canada Gardens, Wembley.
New project wins included Embankment West in Manchester and Miles Street, Vauxhall, London.
The company’s forward order book stands at £115m and it is debt free,
Gareth Simm, third generation Simm family member and managing director said: “I am very proud of this set of results.
“We have come a long way since my Grandad Ernie Simm invested £200 in setting up the company in the 1940s and I’m sure he would be proud of what we have achieved of late.
“He fostered his business on a philosophy to ‘build trusted relationships’, which is exactly the philosophy we live by today.
“That’s why our project handover score stands at 8.9 out of ten, 90 per cent of our work is repeat business and 100 per cent of our customers say they would work with us again.
“This is testament to our employees, so I would like to take this opportunity to say thank you to them for their hard work and dedication.”
John Lennie, the company’s UK director, added: “HE Simm is a fantastic place to work and to have been involved in such a successful growth period gives me great pleasure.
“I look forward to the year ahead and beyond and I am excited about the developments yet to come.”
