Exeter City Council Retrofit Scheme

Low Carbon Exchange were appointed by Exeter City Council to retrofit their housing stock. To date, we have delivered CWI extract & refill, loft top-ups, installation of Solar PV and heating upgrade works, to approximately 394 properties. The works we have carried out are helping Exeter City Council come closer to achieving their net zero targets, minimising fuel poverty and increasing residents’ quality of life.

Location: Exeter
Duration: 2 years (2020 – ongoing)
Value: £2.6 million
Expertise: Whole House Retrofit
Sector: Social Housing

To date, we have delivered approximately 394 properties. This project is still ongoing and we have recently secured another two years where we will be delivering an additional 400 properties. The project was funded by capital investment and LAD 1A & LAD 1B funding steams. The future of this project (2023 onwards) will incorporate SHDF wave 2 funding. Due to the fact the project is part funded, we have delivered in accordance with PAS2035.

What the client wanted

The aim of this project was to increase the energy efficiency of Exeter City Council’s housing stock by bringing them from an EPC rating of D/E/F to C and above. The intended outcome is to reduce fuel poverty across Exeter’s housing stock, in turn reducing residents’ utility bills.

How we helped

To achieve this, our Retrofit Assessor carried out relevant assessments and surveys. This would determine what measures were most suitable to increase energy efficiency.

Following that, our Retrofit Designer put together a package of design related information determining the unique combination of energy efficiency systems, products and materials that should be used to achieved the desired energy efficiency outcome.

Prior to the installation of energy efficiency measures, we had to undertake ancillary works enabling us to retrofit the selected properties.

Our Project Manager oversaw the project from inception to completion. They liaised with building owners, residents, and other project stakeholders to ensure effective management of the Project. LCX supervised all the works carried out, including cavity wall insulation (CWI) extract and refill, loft insulation top-ups, the installation of 3kW and 4.5kW Solar PV systems, and heating system upgrades.

To ensure residents understood how their new systems work, we visited each property and educated them on how to use them while answering any questions they may have. Additionally, we provided each resident with a bespoke Resident Handover Booklet containing information on all the systems installed at their property.

As this project is still ongoing, we will closely monitor all developments in the market. Should any emerging technologies which are more energy efficient arise, we will take them into consideration when advising on future measures for whole house retrofit.

Survey results showed that properties’ EPC ratings increased from D-F to A*-B. To demonstrate the performance of the new systems and give residents greater control over their energy usage, we installed smart monitoring systems to all of the properties worked on.

Key achievements

  • Helped minimise fuel poverty through significant reduction in utility bills (e.g., one resident went from £30/week to £30/month)

  • Helped Exeter City Council take a step closer to achieving their net zero goals by increasing their properties from a D/E/F EPC rating to a high B & A rating. With four properties becoming carbon positive.
