Client: Wandsworth Borough Council
Project: Replacement & Upgrade of Communal Heating and Hot Water System
Location: Hyacinth Estate Roehampton SW15
Size: 144 Properties (32 Sheltered & 112 Residential)


A two phase project that consisted of first the installation of a new boiler plant, new underground distribution pipework to the whole estate, new heating and hot/cold water services to 39 Sheltered Accommodation units.

Secondly the installation of new external communal heating distribution to serve new heating, hot & cold water system to blocks (112 properties).


The heating  replacement contract was carried out in two separate planned phases. The works included within phase 1 was the replacement of the existing central boiler plant, associated equipment, with new condensing boilers, flues, pumping and pressurisation equipment. The works also involved a new Trend BMS installation and the provision of new buried pre-insulated distribution pipework throughout the estate to serve 144 individual flats.

The new underground distribution pipework was installed across grassed areas, paths and road ways, with suitable traffic management in place to ensure access for residents at all times. A temporary packaged boiler room was provided during the boiler replacement works and the new distribution pipework was installed in conjunction with the existing system to ensure that the residents had heating and hot water at all times.

As part of Phase 1, full central heating was provided into the 32 Sheltered Accommodation properties, including low surface temperature radiators and individual temperature control. Generally the new distribution pipework was terminated within pits outside the remaining flats, for connection under the Phase 2 element of the work.

The Phase 2 works also included full central heating to the remaining 112 properties, including radiators and individual temperature control.

During both Phases a Customer Liaison Officer was engaged to keep residents fully informed throughout the contract and to enable all works to be carried out whilst the building and dwellings were fully occupied.


Works were completed to a high standard. Both Phase 1 and Phase 2 were difficult and challenging in nature as there were numerous Health & Safety, access and asbestos issues. A driven & well managed team of Operatives who completed these works to the highest quality is the standard we will consistently seek to replicate for all future projects.

Client Testimonial:

“T Brown Group have worked for Wandsworth Borough Council on a number of contracts for many years ranging from Term Maintenance contracts to one off housing regeneration projects in the HVAC industry. Recent contracts were for the replacement/upgrade of a housing estates, communal heating and hot water system on the Hyacinth Estate Roehampton SW15 and also Replacement boiler project Boroughwide which is still onsite at present and going very well. Both projects comprised of multiple, high rise dwellings comprising of council tenants and leaseholders. The works involved replacing the heating and hot water systems within the residents properties and completely replacing the existing system set up. T Brown Group were thoroughly professional in the management of the contracts under Dominic Brown (Designated Contract Manager), who went over and above the call of duty in terms of their proactive approach to meeting the employers requirements. Furthermore, we received positive feedback from the residents for their considerate and courteous nature. The works completed By T Brown were to a very high standard and the support service provided during defects Liability Period was good also. Both of these contracts were difficult and challenging in nature as there were numerous Health & Safety issues to overcome and access and asbestos issues were many. T Brown Group Excelled in their handling and implementation of their operatives and satisfactorily completed the contract.

They have also been the contractor for the maintenance of half the borough’s gas servicing and responsive repairs for approximately 8 years, and have just won it for another 5 years.

In all the contracts I have managed on behalf of Wandsworth Council’s Housing Department, T Brown Group were always very responsive and helpful throughout the contracts.”
