DEF is a software house.

For the last three decades we've been developing public sector software for the Local Authority market. Yet more than 30-years on, we're still thoroughly enjoying this wonderful journey.

In terms of the software and where it goes, we deliver our products into Planning (Development Control), Building Control, Land Charges, Highways, Environment, Legal and Licensing. Our reputation across these areas is one of the very best in the UK...just ask our clients!

From dedicated County Planning and our Building Portal through to S106 software and Legal Agreements, innovation and workflow are at the very core of our Public Sector software agenda. The demand upon our clients never stands still; in turn, nor do we.
