<p>Heroin assisted treatment (HAT) or diamorphine assisted treatment (DAT) is a clinical intervention supported by the 2017 United Kingdom-wide drug treatment guidelines. Local authorities in England are responsible for commissioning drug treatment services, including whether to commission HAT services. Local authorities’ individual financial allocations and assessments of local need will determine if HAT is a viable intervention. The Government supports areas which pursue HAT where the relevant licences are obtained from the Home Office. In 2021, the former Public Health England provided additional guidance on commissioning and developing a HAT service if local authorities choose this approach.</p><p>The 10-year drug strategy is supported by a new investment of £780 million, including £532 million for local authorities to invest in treatment and recovery services in addition to the Public Health Grant. This allows local authorities to determine which interventions could augment current treatment systems. The Office for Health Improvement and Disparities provides oversight of local delivery and continues to monitor implementation against the aims of the drug strategy.</p>
