Web Development

Transport for London's new website.

Transport for London's new website.

Since 1997, our web development work has grown year-on-year. This dramatic growth, largely based on word-of-mouth recommendations and also repeat business, is illustrated by our growth and our ranking as 3rd largest technical agency in the UK in the eConsultancy Top 100 Digital Agency survey.

Significant differences that make us stand out

Security and assurance

CDS’ delivery credentials include:

  • ISO9001 Quality Management
  • ISO27001 Information Security Management
  • ITIL accredited service desk
  • CESG, and
  • GSi accredited security.


We are one of the few agencies that provides end-to-end design, web development and implementation, programming, hosting, helpdesk and ongoing servicing of national-scale web programmes.

Content management and web development

Many agencies partner content management software vendors and CDS is no exception. But a software program is only one enabler of a content management strategy. Our service encompasses end-to-end content creation, migration, optimisation, delivery and support.

We will always implement an appropriate solution for the use case for our client. Our default recommendation for a public facing site is responsive design but where there is a specific use case we will also create dynamic serving sites or a specific mobile site alongside the desktop site. .

Technical proficiency

Version control, architecture, release management, test management, service desk fault management and problem management are all services our dedicated teams deliver on a daily basis. The provision of all these services places us head and shoulders above our competitors.
