How Grants4Growth have helped one Lincolnshire firm become a market leader

For the past 18 years, DoorTechnik of Lincoln has been designing and manufacturing high-security doors for customers across the globe. 

In 1999, Graham White, DoorTechnik’s founder, took the decision to branch out from the family farming business and enter what he believed to be a growing and exciting market in the manufacture of steel and glazed doors built to the highest specifications. Primarily the business sells to clients within the commercial, hospitality and service sectors but will also take commissions for high end residential properties or residences that need enhanced security.

Operating from Thorpe on the Hill in Lincoln, the business now employs 20 people and turnover is in excess of £1.25 million. Graham still gets involved in the day-to-day running of the business and oversees the design of the doors before they are produced and assembled on site.

Continuously looking to improve the quality of their doors and streamline the production process, DoorTechnik wanted to bring in house the shot blasting treatment, currently performed off site.  Bringing the process in-house would enable production cost reductions by saving on subcontractors and transportation, as well as decreasing job turnaround times and increasing capacity for more orders. It would also ensure that quality standards were kept at the highest levels.

Sarah Rydel, DoorTechnik’s technical advisor, contacted Grants4Growth. Sarah said; “Grants4Growth were interested in our future plans and the impact the purchase would have on our business growth. We explained how it would help us to reduce our production costs and become more competitive and responsive to our customers. The application process was straightforward and we got a decision in under three weeks. We secured a grant of £9400 which allowed us to purchase the kit without too much of a delay. We are excited about the future and having secured planning permission to extend our operation on our current site we are looking to increase our production capacity further in 2018. Increased production capacity to meet demand comes with its challenges but we are confident in our ability to grow the team and establish ourselves firmly as the market leader in our field”.

The Grants4Growth programme offers capital grants between £1,000 and £25,000 to eligible SMEs who can demonstrate growth potential. If eligible, Grants4Growth can pay up to 28% of the overall cost and help to purchase capital assets to promote business growth and job creation.
