About us

Company Background

We are a friendly, creative, problem-solving company with an impressive track record of expertise in housing development solutions. It started back in 1994, when our experience in both the private and public sector led us to develop our first software product, a land appraisal tool. This was quickly followed by ProVal, which is now the market leader in development appraisal software. Since then, we’ve developed tools for project management and stock profiling and we’re constantly innovating, with new products on the horizon.

This is supported with excellent customer service, accredited training and wide-ranging consultancy services.

We are here for the long term for our staff and our customers by being financially prudent and innovative.

SDS provides the housing industry with software products and consultancy services for both the public and private sector. The company was established by David Shelton and in January 2009 Phil Shelton took over and now heads up the team.

All our software is written in house at our base in Cranleigh, Surrey. When you need support, the team is on hand via phone, email or weblink so you never have to wait long.
