About Us

Cadential is the trading name of Alan Spiller and associates.  We are an independent IT company specialising in providing solutions and services to home workers, small businesses and schools.  We are based in Steyning, West Sussex, and cover most areas of South East England.

Established in 1998 we have been successfully trading relying on recommendation and repeat custom.
With many years experience in IT we aim to offer jargon free, cost effective and honest advice, service and support. We can offer fast response times, specialist IT knowledge and excellent customer service.

We can provide equipment, software and supplies from all the major manufacturers, from a single piece of software through to a complete network. We offer flexible IT support options to our customers, from ad-hoc telephone support, through to on-site contracts. We can also offer remote assistance through remote access technology.  Please see our IT Services page for more information.

Having previous experience in the field of construction, we maintain this link by being UK resellers for three major low cost Computer Aided Design packages, Cadvance, General CADD, and Cadopia IntelliCAD. We can supply low cost CAD solutions including workstations and plotting equipment, and can provide CAD drawing and translation services.  Please see our CAD pages for more information.

Helmut Lusser, Chairman
Global to Local Ltd

“As a micro business with all staff working remotely we are very reliant on our IT systems. When we looked around for an IT support service that would meet our particular needs we came across some suppliers that proposed inappropriate and expensive solutions. Alan was recommended to us and we chose him for his expertise and practical approach. He has given solid advice about the sort of equipment and software we need. He does the research for us, and has bought, set up and maintained our systems. He is always very responsive and can talk us through most issues over the phone, or sort them out by logging in. Alan’s service helps us to keep our business running efficiently. It saves us time and we have peace of mind knowing that our machines and data are safe.”

“Alan Spiller has worked for me on an ad-hoc basis for the past 9 years. He has always given total commitment to the roles asked of him and his technical knowledge is excellent. My group provides managed ICT services for schools and it is essential that all staff working in schools are honest, trustworthy and reliable. Alan is all of these and has forged good relationships with both colleagues and customers alike. I would not hesitate in employing Alan again.”

Alan has always demonstrated a very high standard of professional competence, been pleasant to work with, and readily available - either remotely or, as necessary, in person - especially in moments of IT crisis! I am delighted to recommend his services.”

“Alan has undertaken contract work for me since 1998 and has always been reliable, polite and professional in his dealings with both colleagues and our customers. He is thorough, well-organised, adaptable and is able to work with minimum supervision whilst being part of a team. He is punctual, works well under pressure, deals with our customers very well and can communicate clearly both verbally and in writing. He would be an asset to any organisation to which he belongs.”
