## Summary

Housing 21 procured works to install domestic unvented hot-water cylinders and individual domestic gas boilers at Carlton Crescent. The requirement covers heating and hot-water equipment in a residential housing setting, with the associated boiler installation work classified under CPV 45331110. Housing 21 is the buying organisation and is based in Birmingham. The named requirement is focused on the installation or replacement of domestic heating and hot-water assets rather than general building maintenance, so it is most relevant to heating, plumbing and mechanical-services contractors able to work in occupied or managed residential properties. The procurement contains one completed lot covering the full stated requirement at Carlton Crescent.

This below-threshold procurement used a limited competition and has reached the awarded stage. The single lot was completed and the contract was awarded to GOS Heating Limited, an active award. The contract was signed on 7 August 2026 and runs from 7 September 2026 to 30 October 2026. Its value is £61,779 excluding VAT and £74,134.80 including VAT. The selected supplier is GOS Heating Limited, based in Preston. The published outcome records boiler installation work as the awarded category. The procurement was evaluated through a below-threshold limited competition; the available outcome data identifies the route used but does not provide a separate breakdown of award criteria or scoring.

For a competitor, this award demonstrates a defined Housing 21 requirement for domestic gas-boiler installation and unvented hot-water-cylinder work at a residential site. A credible future supplier would need practical competence in both heating and hot-water systems, including the installation, replacement and commissioning of individual domestic gas boilers and unvented cylinders. The work is suited to an SME-sized heating contractor with the operational capacity to deliver a concentrated programme rather than a major construction firm requiring a large, multi-site package. Relevant experience in housing or other managed residential environments would help demonstrate safe coordination, reliable attendance and quality installation. Contractors tracking Housing 21 should treat this procurement as evidence of demand for specialist domestic heating works procured through limited competition.
