TIA are proud to contribute to the UK’s national defence

TIA was formed in October 2015 by the current Directors, a coming together of a broadly experienced team with vast knowledge, understanding and a great track record in the provision of specialist Defence and Government solutions having worked together previously in a US corporate technology company. This formation re-united a great set of skills, capabilities and personal reputations to form a business aimed at removing pains and delivering gains to Defence and Government Project Managers and Technical leads for Electro-mechanical systems and solutions.

our design process


From the outset we have unswervingly invested a minimum of 25% of our profits into the business annually, with a focus on delivering on our promises whilst continuously improving our skills, capabilities and resource. We have maintained an enviable On-Time-In-Full delivery record and gained numerous important accreditations including ISO9001:2015, Cyber Essentials, NCSC approved TEMPEST vendor, NATO approved TEMPEST vendor and close support to major programs through our Defence Prime partners and UK Gov. We now feel that we have the profile, reputation and corporate know-how upon which to develop and grow the business in line with our values.

He is intimately familiar with all stages of the acquisition, design and through life processes having experience across the board as a contributor and manager.

He is the ‘go to’ guy for his key expertise gained from several years in the Defence/Government and commercial markets, specifically in the Electromagnetic Effects (EME/EMC) and TEMPEST sector with recognition by the UK National TEMPEST Authority (GCHQ). All aspects of the EMC and TEMPEST approval process undertaken from design and requirements specification to qualification management, including installations and the associated safety factors of RF RADHAZ. A full appreciation of project requirements to determine objectives: driving design for qualification to achieve integration and intra/inter system interoperability within the electromagnetic environment.
