Our Story
1989
Comtek started in 1989 as a one-man operation repairing modems and network hardware products. Without any external funding the company grew, despite the recession, by providing network hardware and computer repairs to computer maintenance providers. Later Comtek became involved in refurbishing legacy and current network hardware products and reselling them throughout the U.K. and Europe.
1995
A name change for Comtek, to what we now it as today, Comtek Network Systems. This was done to reflect the greater focus on telecoms and networking equipment that Comtek was now repairing.
1997
Comtek’s growth has been impressive. During early 1997 the Welsh Development Agency encouraged and supported Comtek in expanding its operations to North Wales (Deeside). As a result, Comtek moved most of its operations to Deeside Industrial Park.
2001
Early in 2001 Comtek acquired the repair business of Case Technology’s manufacturing and repairs business following the bankruptcy of this company.
2009
In 2009 the global communications giant Nortel filed for bankruptcy and began to sell off various parts of its business. Much Nortel equipment was thus facing vastly reduced or totally withdrawn technical support. With customers across the globe facing withdrawal of support for telecoms products which formed the backbone of their networks a potential crisis was looming. The obvious solution at the time would have been for these companies to rip out billions of pounds worth of infrastructure and start again. This would have drastically increased the amount of equipment sent to landfill and the costs of underpinning their businesses.
Comtek therefore launched its Nortel Rescue Programme to offer a repair /remanufacture/refurbish service for any legacy and end of life Nortel equipment which was facing withdrawal of support.
2011
Comtek opens its Northern Ireland facility as a reaction to increase in demand for its repair services. Today this allows Comtek easy access to European markets and customers, greatly reducing our customer shipping expenses.
2014
Sorrento Networks International is acquired by Comtek Network Systems, becoming the UK’s only manufacturer of fibre networking equipment.
FUTURE
Company has continued to diversify its offering and now provides repair services for rail and highways equipment such as variable messaging signs and cameras. It is also pushing into the renewable energy market by providing repair solutions for solar and EV chargers.
