Mercury Systems have been installing and maintaining the CCTV, Access Control, Intruder Alarms and Nurse Call Systems at Barnet Hospital for over 10 years and the standard of workmanship has always been excellent.

The turnaround in supplying quotations for additional works has always been good, and prevents any delays with planned works.

The engineers are always polite and courteous to Bouygues staff members, employees of the NHS and patients alike and I would not hesitate in recommending Mercury Systems to other potential customers.

I have been employed within the Security Industry for the past twenty-five years, during which time I have used the services of numerous suppliers.

For the past eight years Mercury Systems have been our nominated supplier. They recently re-won the tender for our company (a large corporate) and are again in place for the next three years.

As a customer we are demanding and frequently have work that is complicated or requires urgent attention in order to keep our business open and trading. Mercury Systems rise to the challenge, every time.

I have no hesitation in recommending Mercury Systems . They are thorough from planning to completion of a job, and the aftercare service is equally professional.

Mercury Systems are second to none.
