Management Team – Security Installation Services Ltd

Bradley Mak


Bradley is our Managing Director and started his career as an apprentice Locksmith, later venturing out as a sole trader in 1991 and founding Security Installation Services Limited in 1993.  With over 30 years’ experience covering a wide aspect of the industry, he has a wealth of knowledge and puts it to good effect for the benefit of our customers.

Bradley can be found at his desk from 9-10am most mornings where he’ll be sourcing the latest deals and catching up with his emails.  This is the best time of day to contact him for technical advice or for a chat about on-going or up and coming projects.  The rest of his day will be spent on the road, either repairing, maintaining or installing our security equipment and systems.

In what little spare time he has, Bradley can usually be found in the workshop with his new found love … a CNC milling machine.  Never mind the kids and missus, eh Brad?!



Donna Mak


Donna is our Company Secretary and also married to the boss.  A couple of years’ experience as an accounts assistant was enough to support Bradley right from day one with all things admin and finance related.  Having been involved in the growth and development of the business since the beginning in 1991, she is well placed to answer most queries and what she doesn’t know, she will find out.

We are proud of our high quality customer service and Donna is fundamental in ensuring that our customers are kept as informed as possible, from the time of their initial enquiry, right through to the after service care.

With even less spare time than Brad – being the milling machine widow that she is – Donna is usually found entertaining their four children still at home, or letting loose on a netball court!
