rak was established as R & A Kay Inspection Services Ltd in 1984 to provide professional plant inspection services to the petrochemical industry. We have maintained this service and continued to diversify into the industrial gases, utilities and chemical sectors not only supplying inspection resources but a fully accredited 3rd party inspection service.

With UKAS accreditation, clients can be assured of our ability to undertake all activities professionally and authoritatively and it is an unequivocal demonstration of our technical competence.


At the start of 2020, rak restructured the management team in order to re-focus on growth and development of future business opportunities. With strong foundations to build on, rak plans to further expand our client base, invest in the training and development of our current inspection engineers and work with our clients to create opportunities to develop the next generation of trainee inspectors.

All our engineers are encouraged to reach their full potential and sponsored to gain industry recognized qualifications and membership of relevant engineering institutions. With this growing team we are well placed to continue our development into new sectors and markets and to satisfy the evolving needs of our clients.

rak has been successful in expanding our accreditation to include non-destructive testing (NDT) inspection services. We now boast inspection teams serving the pressure systems, tankage, civil & structural, NDT and lifting sectors. More recent growth and diversification has seen the company’s client base expand into the power generation, utilities, industrial gases and chemicals sectors.
