Our Employees

Each TSD technician is fully trained in house and through approved manufacturer courses most of which lead to industry recognised qualifications. TSD has always ensured that our technical staff are fully up to speed on all the latest technology and encourage staff to take full advantage of courses, exams & qualifications provided by the various suppliers and manufacturers we use.

We do not employ any sales staff so all enquiries are dealt with by our technicians. You can be confident that your sales enquiry will be handled by an experienced technician who has actually used and supported the products or services they recommend. We do not pay our staff commission on sales so you can be confident that each solution is reached by a technical decision rather than a financial one.


We build our own PCs and servers and can supply pre-built systems or specify Dell, Fujitsu Siemens & HP hardware where appropriate.


We will work with you to help you plan your new IT systems or advise you on how you can get the best out of what you already have. We will talk to you and your staff and most importantly listen to what you want and what your concerns are. It is only by fully understanding your business that we can even begin to formulate a solution that fits your needs and budget.
