## Summary

Southern Housing procured gas appliance maintenance services under its Gas servicing and replacements requirement, Lot 1, covering London North. The scope is identified as gas servicing and replacements; the listed service classification is gas appliance maintenance (CPV 50531200). Delivery locations are listed across the East Midlands, West Midlands, London, South East and South West of England, so this requirement extends beyond the lot’s London North title. The buyer is Southern Housing. The procurement is categorised as a service, aimed at maintaining gas appliances and carrying out replacements. The stated scope does not break down appliance types, replacement volumes or specific servicing tasks, but establishes a multi-region housing maintenance requirement for suppliers able to deliver gas servicing and replacement work.

The procurement is complete and was awarded to T.S.G. Building Services PLC. The award was made on 22 September 2026. The awarded value is £20 million, with a contract period from 1 October 2026 to 30 September 2031. The stated tender estimate is also £20 million. The process used a selective route as a call-off from a framework agreement. The submission deadline was 1 September 2026 at 13:00. This is identified as Lot 1; no further lot breakdown is provided. The procurement is marked as suitable for small and medium-sized enterprises. No award evaluation criteria are stated in the published procurement data, so the basis on which competing framework suppliers were assessed cannot be described.

This award provides evidence that Southern Housing buys gas servicing and replacement work across several English regions, rather than London alone. The requirement is substantial and long-running, involving ongoing appliance servicing as well as replacement work; a credible competitor would need capacity to manage both planned maintenance and replacement delivery across a geographically dispersed housing portfolio. The buyer used a framework call-off, so suppliers seeking to compete for comparable work would need access to an appropriate framework and the ability to meet its call-off requirements. The selected supplier is identified as an SME, showing that this contract was delivered by a small or medium-sized business. The available scope does not specify particular technical accreditations, appliance volumes or performance measures, so these should not be assumed as selection requirements.
