Introduction
Providers extending into TDDI for a children's or young people's service sometimes assume the requirements are identical to an adult-focused TDDI application with a few extra safeguarding checkboxes. In practice, CQC expects genuinely distinct evidence in several areas — this article covers what's actually different, not the full TDDI process, which is covered in our main TDDI registration guide.
Why children's TDDI is treated differently
Safeguarding requirements for services involving children go beyond the general safeguarding policy expected of any CQC-regulated service — they need to reflect children's-specific safeguarding legislation and practice, not an adult-focused policy with "children" substituted in.
The underlying reason is that a child's capacity to consent, to raise a concern, or to recognise when something is wrong is fundamentally different from an adult's, and CQC's assessment of a children's TDDI service reflects that throughout — not just in the safeguarding policy document itself, but in how staff are trained, how incidents are escalated, and how care is planned and reviewed.
The additional evidence CQC expects
Beyond standard TDDI evidence, expect scrutiny of staff training specific to working with children (not just generic safeguarding training), care-planning documentation that reflects age-appropriate practice, and governance arrangements that demonstrate genuine oversight of children's-specific risk.
In practice, this means training records need to show completion of children's safeguarding training specifically, not just a general safeguarding module with a children's-services box ticked. Care plans need to reflect input appropriate to the child's age and understanding, and involve parents or carers in a way that's documented, not assumed. Governance meetings and audits should have a distinct children's-services agenda item, evidencing that oversight isn't happening only at the adult-service level and trickling down by assumption.
Staffing and DBS considerations
Staff working directly with children require enhanced DBS checks including the children's barred list, which is a distinct check from the standard enhanced DBS required for adult-focused services — see GOV.UK's guidance on DBS checks for the specifics of which check level applies.
This distinction is easy to miss for a provider extending an existing adult-focused TDDI service into children's care, since staff who already hold a valid adult-services enhanced DBS check may assume it covers them for children's work too. It doesn't — the children's barred list check is a separate, additional requirement, and getting caught out by this late in an application is a genuinely avoidable delay.
Working with other agencies
Children's TDDI services rarely operate in isolation — multi-agency working with children's social care, education, and where relevant, the child's existing NHS clinical team is a real, ongoing part of delivering this kind of service safely. CQC's assessment of governance for a children's TDDI service typically looks for evidence of how information is shared appropriately across these relationships, not just how the service operates internally.
