HVAC Maintenance & Support for Class 170 and 158 Fleets

Request for Information (RFI)

For this pre-market engagement exercise, interested suppliers are invited to provide information in relation to the following matters:

Mobilisation Period

Please outline the mobilisation activities that would be required to commence service delivery and indicate the anticipated timescales for full mobilisation. Suppliers are requested to identify any key dependencies, constraints, or risks that may impact mobilisation timelines. This question is of the highest importance to Northern at this time.

Weekday and Weekend Pricing Differentials

Please provide an indication of the typical cost differential between weekday and weekend service provision. Where possible, suppliers should express this as a percentage uplift and explain the principal factors influencing any variance in rates.

Multi-Site Resource Flexibility

Service delivery may be required across the locations of Hull BG, Newton Heath (NH), and Neville Hill (NL). Please describe how your organisation would manage resources across multiple locations to ensure appropriate service coverage (40 hours per week across sites), responsiveness, and operational resilience at each site. Responses should include details of workforce deployment, scheduling, and any arrangements that support flexibility between locations.

Additional Information

Suppliers are encouraged to provide any further observations, recommendations, or market insights that they believe may assist the Authority in developing an effective procurement strategy and service specification.

Please submit your answers to [email protected] by the end of Wednesday 11/11/26.
