Retrofit and technical research reports

This report focuses on the performance of two Wondrwall installations and compares them with a control property with solar PV and infrared heating panels.

The ‘Evaluating solar PV with electric heating’ project installed 18 solar PV systems and 11 Mixergy smart hot water cylinders in socially rented homes.

The electricity tariffs report first discussed smart time-of-use electricity tariffs offered by energy suppliers which are suited to different technologies.

The ‘Evaluating solar PV with electric heating’ project assessed the benefits of installing solar PV systems in social housing with different types of electric heating.

This project by National Energy Action aims to obtain more accurate data on how much it costs to run various household appliances.

The smart solar in Barnsley project was an innovation project funded by the Energy Industry Voluntary Redress Scheme.

The Wakefield Mega Solar project installed 115 solar PV systems between October 2021 and September 2022.

This report looks at the long-term performance of solar PV systems installed on socially rented properties and discusses issues which may cause lower performance.

This project aimed to install a series of small measures which could complement solar PV systems.

This document is intended to be used as a guide by organisations involved in the delivery of heat pumps in fuel poor homes.

The project was led by National Energy Action and North Devon Homes Ltd.

Insulation was installed on 11 privately owned park homes at 2 sites in Cheshire East district.

This project focused on the installation and evaluation of measures or combinations of measures in homes at risk of fuel poverty.

Ongo Homes installed three different types of innovative full heating systems into 30 properties from their social housing stock.

This project was delivered by YES Energy Solutions in collaboration with North Lincolnshire Council.

After the successful delivery of a project that replaced electric storage heaters with hybrid heat pumps Home Group were invited to run an additional hybrid heat pump project.

This project used Q-Bot’s novel “SprayBot” to install a layer of Elastospray foam insulation to the under-side of suspended timber ground floors in properties in the London Borough of Camden.

This project was delivered by South Holland District Council. It mirrored a similar project with the same partner to compare three other smart heating controls in other council owned properties.

The project was delivered by Aspire Housing, in the Newcastle-under-Lyme area of North Staffordshire. The properties targeted are too far from gas mains to benefit from a gas supply.

This project was delivered by South Holland District Council (SHDC).

This project was delivered by YES Energy Solutions in collaboration with Basingstoke and Dean Borough Council.

This project was delivered by housing association Home Group, who installed 24 Daikin hybrid heat pumps in properties that were also being connected to the mains gas network.

Looped electricity supplies were a cheaper way to add homes to the local electricity distribution network.
