Our Impact

At Blenheim we work with over 11,000 people a year making an impact that not only improves the health of the individual, but has a lasting positive impact on the wellbeing of their families, friends and the communities in which they live. People who use our services are not just people who use drugs and alcohol, they are partners, fathers, mothers, sisters, grandmothers, children, brothers, friends, work colleagues and carers.

At Blenheim, research development and innovative service delivery are integral parts of who we are and the work we do. Read on to find out about the importance of our research and innovation in practice.


Research is an important part of the work we do at Blenheim to promote and share evidence based best practice.

We collaborate with academic institutions and external experts in the field to develop and undertake bespoke research. This enables us to build and contribute to a body of original research, extend our understanding of effective practice in substance misuse and to inform and direct our services in the future.

If you would like to discuss a research project or opportunity please get in touch with the Business Growth Team on bdu@blenheimcdp.org.uk or 020 7582 2200.



Blenheim CDP champions innovative thinking and the power of digital technology to improve the outcomes of individuals with substance misuse problems.

The Innovation Unit was established in 2018, following a merger with Haringey Action Group on Alcohol (HAGA), to do just that.

Our core products currently include:

  • DontBottleItUp – A free online alcohol test providing brief advice and information regarding local resources where appropriate.
  • DrinkCoach Online Coaching – A Skype-based coaching service which delivers Extended Brief Advice to risky drinkers unable or unwilling to access traditional face-to-face treatment services – paid for or sponsored depending on area.
  • DrinkCoach App – A unit, cost and calorie drink tracker app available for free on IOS and Android.

We’re always exploring ways to deliver new and better solutions and invite you to get in touch with us at Innovation@blenheimcdp.org.uk to discuss ideas for collaboration.
