About tScheme

tScheme serves organisations in the trust service provider sector, providing accreditation for the services they supply to consumers and organisations.

Formed in 2000, tScheme is a not-for-profit organisation that aims to improve levels of trust in digital economies. We provide an independent means of establishing and testing the trust of services to recognised standards. tScheme’s growth reflects the rapid growth of online services, particularly those which involve a need for trusted services.

What we do

We support organisations who wish to provide trusted digital services to their customers. We provide a central point for information on best practice, publishing a range of clearly-defined Profiles and assessment criteria. Anyone can benchmark their own service against our Profiles to obtain authorisation for their Trust Scheme Frameworks and services delivered under them.

Assessing your trust service

Assessments and audits are carried out by one of two approved assessors – KPMG and LRQA. Both are recognised by UKAS – the UK's National Accreditation Body responsible for determining the technical competence and integrity of organisations and their services. Both operate independently from tScheme.

Once your scheme has been audited, we assess it against the appropriate Profiles for that scheme type. If it’s satisfactory, we approve your scheme.

Our members

Our membership is drawn from the public, private and third sectors. They join because they believe in the independent assessment of trust services used in the digital economy. Organisations can be tScheme approved without becoming members, but we are moving to a model of automatic membership benefits at point of approval.

tScheme also manages the UK trust service providers list on behalf of the UK government’s Department for Digital, Culture, Media & Sport working with the Information Commissioner's Office.


A number of factors have shaped our development and the services we offer. We keep a close watch on the needs of the market, regulatory frameworks, trends and other factors to ensure our services maintain their relevance and currency. Organisations that use our services automatically become members of tScheme. As a member, they can contribute to the development of tScheme, including the possibility of joining our board.

There is an annual membership fee of £1,000 for each member organisation. This fee amount is deducted from the cost of the tScheme services used.

The tScheme trust mark

Trust scheme providers who have been approved by tScheme can use the tScheme logo to indicate the quality of their process.

Who we work with

tScheme works with a number of different organisations:

  • Scheme (trust framework) Authorities – organisations who want to develop a specific set of Profiles, or add an auditable specification to an existing Profile to support one or more trust schemes they wish to operate. More.
  • Organisations who seek approval to operate under one or more schemes – commercial organisations. More.
  • Independent assessors – who audit and inspect applicants under one or more schemes. At the moment, KPMG and LRQA are our recognised assessors.
  • tScheme members – organisations who deliver trust-based services and support tScheme as the UK’s independent Profiles and approvals body. Members can operate schemes themselves – they can also become applicants for approval. More.
  • Independent domain experts – invited members of our committees who look at our Profiles, policy and processes to ensure they remain relevant, stable and trustworthy.
