Summary of the contracting process

The City of London Corporation procured fire safety and compliance works at Harman Close, Avondale Square Estate, Old Kent Road, London SE1 5PB, and Isleden House, Prebend Street, Islington, London N1 8PP. The works cover two residential blocks containing general-ne needs and sheltered accommodation, including communal lounges and resident facilities. The scope comprises replacement of the existing fire alarm systems with redesigned AICO LD1 systems; replacement of the warden call system with an open-protocol Tynetec Advent XT2 system, or an approved equivalent, ready for digital switchover; AICO environmental sensors in every dwelling; new mechanical extraction in kitchens and bathrooms, subject to surveys and peak-flow tests; and removal of redundant communal cabling to support fire-door installation. This is a public-sector building-services and fire-safety construction requirement.

The procurement is complete following a below-threshold open competition. Enquiries closed on 7 July 2025 and tenders closed on 14 July 2025. The requirement was advertised as one lot, with an estimated value of £650,000 excluding VAT (£780,000 including VAT). VENTRO LTD was awarded the contract, which was signed on 4 December 2025 for £692,779.02 excluding VAT (£831,334.82 including VAT). The contract period runs from 12 January 2026 to 3 July 2026. Evaluation weighted technical quality at 45%, commercial offer at 40% and responsible procurement at 15%, with qualification assessed pass or fail. The tender required evidence of two relevant projects from the previous three years, plus assessment of resources, health and safety, programme, logistics and delivery methodology.

This award indicates demand from the City of London Corporation for integrated fire-safety and compliance works in occupied residential and sheltered-housing settings. A credible future competitor would need demonstrable experience delivering comparable fire-alarm, warden-call, environmental-sensor, ventilation and associated enabling works, with the ability to coordinate several disciplines across occupied blocks. Relevant recent case studies, reliable customer references and a clear record of completing similar projects would be important. The requirement also favours businesses able to provide a suitably structured management and delivery team, identify any specialist subcontractors and control their supply chain. Strong site health-and-safety systems, resident and stakeholder management, logistics planning, building-safety-regulator approvals and a practical method statement would all be central to competing effectively for this buyer’s comparable requirements.

Notice Title

Harman and Iselden House Fire Safety and Compliance Works

Notice Description

The City of London Corporation (the City) invites Tenders for the provision of Harman and Iselden House Fire Safety and Compliance Works Harman Close, Avondale Square Estate, Old Kent Road, SE1 5PB Harman Close is a sheltered housing block situated on the Avondale Square Estate in the London Borough of Southwark. It consists of 39 large bedsit flats, eight one-bedroom flats and one two-bedroom flat built on the ground, first and second floors. There are two lifts serving all floors. All flats have their own kitchens and bathrooms, but there is also a communal lounge on the ground floor where residents can socialise. Isleden House, Prebend Street, Islington, N1 8PP Isleden House is made up of general needs housing and sheltered accommodation. The estate was built in 1948 by the Trustees of the London Parochial Charities. In 1953 the Trustees conveyed the property to the City of London. The estate is centred around a quiet, private courtyard and gardens and comprises of 76 flats, 33 of which are sheltered accommodation for people at the current state retirement age. Sheltered residents have access to the communal lounge. The Corporation currently has issues with both sites in relation to the current fire alarm systems, namely that the smoke detectors do not communicate with the warden call system due to historic lack of maintenance and/or a poor standard of responsive repairs. Consequently, there are waking watches in place at both sites. The Corporation intends to proceed with the following works at both sites (subject to Condition Survey): * Replacement of the existing fire alarm installation with a re-designed AICO LD1 system * Replacement of the Warden Call System supply with an open protocol Tynetec Advent XT2 system (or similar approved) ready for the digital switch over (due to happen in 2027) * Installation of AICO environmental sensors in all dwellings * Installation of new mechanical extraction in the individual kitchens and bathrooms in all dwellings of both blocks (subject to peak flow test results and individual surveys) * Removal of redundant cabling in communal corridors and lobby areas to facilitate fire door installation
