Enfield Council commissioned AgilityEco to undertake a feasibility study for communal heating replacements across 12 large residential tower blocks with failing electric underfloor heating. AgilityEco had previously advised and overseen building refurbishments works to 4 tower blocks on the Exeter Road Estate, resulting in the installation of external wall insulation, glazing and flat roof insulation, financed partly by approximately £1 million of ECO funding. AgilityEco assessed the various communal heating options for Enfield Council, including the technical considerations, costs, financial returns and the various financing options (e.g. ECO, RHI). The assessment could then be broadly applied to the other blocks, all of which are very similar in design and build.
We produced an estimate of the capital, operating costs and technical considerations of the different options considered for communal heating replacement. This analysis enabled us to narrow down the technology choices for the communal heating replacement. Detailed assessment and modelling of the carbon savings was completed. This was also used to inform the potential for ECO and RHI funding where applicable. On one of the Exeter Road tower blocks we conducted a thorough carbon saving assessment by completing a detailed Standard Assessment Procedure (SAP) assessment.
Combining the work on capital and operating costs with our assessment of the ECO and RHI funding potential has enabled us to rank the communal heating replacement options and recommend an optimal way forward for Enfield Council. We continued to support Enfield Council through the design, procurement and installation phases of the project. Enfield Council eventually selected an innovative ground source heat pump design, with a communal loop feeding individual heat pumps in each dwelling. AgilityEco also secured ECO funding for the heat pump contractor overseeing all compliance requirements for the energy company funder.
AgilityEco has provided consistent, highly organised consultancy and support to everyone involved in delivering this project for Enfield Council. For us in particular, AgilityEco quickly secured our ECO funding and seamlessly managed compliance requirements, enabling us to focus on installing Enfield’s heat pump systems. The overall result is a potential saving of as much as £500 a year in energy costs for each family.
