Thirty-eight two-, three- and four-bedroom terraces and semi-detached properties on Cowley Close in Northampton, were identified as having traditional electric storage heaters, which were inefficient and expensive to run. Some customers could not afford to turn on the heating and others stated that their heating bills were in the region of £200 per month.
The aim was to install the most energy-efficient and affordable technology available to off-grid properties in order to remove residents from fuel poverty, while meeting emh homes’ target energy-efficiency SAP rating of 55.
A “whole house” approach was adopted, linking the replacement of the storage heaters with efficient air-to-water heat pumps to broader reinvestment works (such as the upgrading of kitchens and bathrooms or new cavity wall/loft insulation). This partnership enabled the team to carry out just one visit, thereby delivering genuine savings or differences to customers’ lives with the minimum of disruption. As a result, customers’ heating bills were more than halved and the properties moved from Band E (SAP rating: 39-54) to B or C (SAP rating: 69-70).
