The UK Department for Transport has published fresh guidance titled Guidance: Bus service improvement plans, dated 4 November 2026, setting out how local transport authorities and bus operators can work together to develop and maintain their bus service improvement plan (BSIP).
The document is presented as practical advice for the two principal groups responsible for planning and delivering local bus services. It addresses both the initial preparation of a BSIP and the processes for keeping it under review, stressing joint responsibility between authorities and operators.
Local transport authorities and bus operators are identified in the guidance as the primary partners in producing a viable, updatable plan. The publication underlines that collaboration is central to producing a BSIP that reflects local needs and operational realities; it does not prescribe a single model for partnership working.
What the guidance sets out
The guidance explains the mechanisms by which authorities and operators can agree priorities, set objectives and sequence interventions, while also considering how plans should be maintained once in place. It frames the BSIP as a continuing programme of work rather than a one-off document, with an emphasis on review and adaptation.
The advice is intended to be applicable across differing local contexts, and it is described by the Department for Transport as a resource to support consistent practice. It provides a common reference point for those preparing or updating plans, enabling clearer dialogue between decision makers and delivery partners.
Practical implications for authorities and operators
For local transport authorities the guidance offers a template for engagement with operators and other stakeholders, while for bus operators it provides a structure for contributing operational insight and aligning service proposals with local objectives. Both parties are encouraged to adopt procedures that allow the BSIP to be revised in response to changing demand, service performance and local policy priorities.
The Department for Transport frames the guidance as a means to improve the quality and coherence of BSIPs across the country by clarifying roles and expectations. It aims to make the process of developing and maintaining a plan more transparent and repeatable for all concerned.
The publication date of 4 November 2026 places the guidance in the current policy cycle and makes it the latest formal advice from the Department on this subject. The Department for Transport is identified as the authoring body of the guidance, which should now be available to authorities and operators as they prepare or refresh their BSIPs.
The guidance is likely to be used by those charged with producing local plans and by operators seeking a clearer framework for partnership working. Authorities and operators can refer to the Department for Transport guidance when drafting, updating or maintaining their bus service improvement plans, using it as a shared basis for collaboration and ongoing plan management.
