Diabetes Prevention Programme (DPP)

NCL Wide

The NHS Diabetes Prevention Programme provider changed from Xyla to LWTC (Living Well Taking Control) on 1 August 2022. Please note that referrals made to the old provider will no longer be automatically forwarded to LWTC; these will be sent back to your practice for re-referral.  

Please ensure you complete the form called LWTC NDPP Referral Form NCL and email to hex.ndpp.ncl@nhs.net

If you need support to identify eligible patients, please see the NDPP Guide to EMIS Searches on the website.  

If you have queries about NDPP, contact Dana.hayes@islington.gov.uk

The NHS Diabetes Prevention Programme (DPP) is a face-to-face and tailored behavioural change programme available to people who are found to be pre-diabetic on their blood tests (HbA1c 42-47mmol/mol) or patients with a past diagnosis of gestational diabetes mellitus (GDM). 

The nine-month programme offers patients advice on diet, exercise and healthy lifestyle through a range of support including sessions, motivational interviewing and digital elements including an app with videos. 

Patients that are unable to obtain a blood test due to Covid-19 can now self-refer by completing the Know Your Risk tool (see External Links). Participants with a score of 16+ are eligible to register.

Many people who are eligible for the programme do not speak English as a first language and, as such, should not be referred through mail-shots. See Downloads for leaflets in other languages.

IT Tools are available to support the referral of patients to the programme. DPP eligible patient searches are deployed via NHS NCL ICB enterprise search and reports. 

CPD-accredited training

The Royal College of GPs (RCGP) has developed an e-learning module on the NHS Diabetes Prevention Programme for GPs, practice nurses and other practice staff (see External Links). 

The free 30-minute module is CPD-accredited and covers: 

  • what non-diabetic hyperglycaemia is
  • what the NHS Diabetes Prevention Programme is
  • how it works
  • who is eligible.

It can be accessed by creating a free account on the RCGP learning site. 

Eligibility criteria
