## Summary

The London Borough of Wandsworth has completed a procurement process for construction work titled "Void Rear Extension at 9 Pentlow Street." The contract, which involved the development of a new single-storey rear extension, loft conversion, and interior refurbishment with mechanical and electrical service upgrades, was awarded to Collinstown Construction Ltd. Located in London, this public authority embarked on a limited competitive procurement method with a focus on building construction in the UKI region. The contract began on 2nd June 2025 and is set to conclude on 26th September 2025, with a signed value of £244,380.20 GBP.

This tender provides significant business growth opportunities for companies involved in construction, refurbishment, and landscaping services.

The limited competition nature of the procurement suggests that firms capable of offering high-quality, cost-efficient solutions with experience in public sector contracts stand to gain the most. Large-scale contractors like Collinstown Construction Ltd, which have demonstrated efficiency in prior projects, are particularly well-suited to compete in this field.
