Check out this poster case study with additional information about what Limbic achieved during their time on the Accelerator programme.

NHS problem

Mental illness is the largest cause of disability in the UK. One in four adults experience a mental health problem each year, costing the NHS £14.6 billion (11% total budget). However, there is insufficient clinical supply to match patient need, leading to long wait times for vulnerable patients, which is known to negatively impact health outcomes. In NHS talk therapy services for common mental illness, it is estimated that 25% of the total budget is spent on initial clinical assessments. Digital innovation to support clinical assessment is highlighted as a key area to increase service capacity.

The solution

Limbic has developed a web-based AI-chatbot (Limbic Access) specifically for NHS primary specialist care for mental illness – the Improving Access to Psychological Therapies (IAPT) services. The software integrates with service websites by pasting in just two lines of code, and is capable of screening referrals, collecting patient information, and improving accessibility to mental health support.


Having launched in January 2021, Limbic is currently working with 21 IAPTs across 17 Clinical Commissioning Groups (CCGs) and has helped over 30,000 patients access care.

Limbic will improve quality of NHS service delivery by:

  1. Improving patient experience/engagement
  2. Pre-screening referrals for service eligibility
  3. Improving equality of access (eg. non-English- speakers; BAME communities)
  4. Creating service efficiencies to reduce costs

Importantly, the software has already proven it can free-up clinical and administrative time by automating the processing of new referrals and reducing the time taken to complete a high quality clinical assessment (currently accounting for 25% total IAPT spend).
