The London Borough of Havering intend to develop a Integrated Community Smokefree Service designed to provide comprehensive support for individuals seeking to quit smoking and maintain long-term abstinence. The Integrated Community Smokefree Service will prioritise outreach and tailored cessation support for individuals with severe mental illness (SMI) and those affected by substance misuse, recognising the disproportionate smoking prevalence and barriers to engagement within these groups. Through co-located delivery, assertive outreach, and integrated referral pathways, the service will aim to embed tobacco harm reduction into wider care planning and recovery models. This approach reflects Havering´s commitment to inclusive, preventative health services that address complex needs and promote sustainable behaviour change across communities. The procurement is being conducted in accordance with the Competitive Flexible Procedure under the Provider Selection Regime (PSR). Contract duration is 24 months Available Extensions - 12 months + 12 months
