About TetraLogical

We're a boutique company, with lots of experience and a whole new attitude.

We formed TetraLogical in 2019 because we saw the market become more driven by legal compliance than meeting the needs of different people. Compliance is important but it doesn't guarantee inclusion, so we bridge the gap between the two in intelligent ways tailored just for you.

We like new ideas and finding pragmatic solutions to complex problems. We know that inclusion takes many forms, so our services encompass knowledge, experience, strategy, assessments, and development.

Our principles

We put people first: you and your customers, our partners and employees, and everyone we meet. TetraLogical is founded on four principles that mean everything we do is:

  • Inclusive: We consider everyone and make decisions that exclude no-one.
  • Efficient: We work effectively and deliver quality solutions with a minimum of wastage.
  • Ethical: We make decisions for the good of our clients and their customers, our employees, and for the world at large.
  • Safe: We respect privacy and manage all data securely.

Our people

Every member of our team has more than 20 years experience in the technology industry; we've all been involved in accessibility since its earliest days on the web.

We're members of the W3C, where we contribute to standards like the Web Content Accessibility Guidelines (WCAG) and Accessible Rich Internet Applications (ARIA), so we put a rare level of technical knowledge at your disposal.

We're on the UK Government G-Cloud Framework, where we provide accessibility services for the UK public sector. You can find information about the services we provide on the GOV.UK Digital Marketplace.


Our community

We dedicate some of our time to supporting knowledge share in the technology community. This includes contributing to community projects, conferences, and mentoring schemes.

Inclusive Design 24

Inclusive Design 24 (#id24) is a free 24-hour online event for the global community. It celebrates inclusive design and shares knowledge and ideas from analogue to digital, from design to development, from planners to practitioners, and everything and everyone in between.


Inclusive Design Principles

The Inclusive Design Principles are designed to give anyone involved in the design and development of websites and applications - designers, user experience professionals, developers, product owners, idea makers, innovators, artists and thinkers - a broad approach to inclusive design.
