Kelda Showers Recognised in RdSAP
Helping Social Housing Providers Improve EPC Ratings and Cut Energy Costs
Kelda Showers’ groundbreaking Air-Powered™ technology is now officially recognised within RdSAP – the UK’s Reduced Data Standard Assessment Procedure and the official methodology used to assess the energy performance of homes in the UK.
This recognition confirms that installing Kelda showers can positively impact a property’s Energy Performance Certificate (EPC) rating – and we are the only shower to be recognised within this model.
For local authorities, housing associations, and social landlords, this provides a new, proven way to improve energy efficiency, reduce carbon emissions, and support tenants with lower energy bills – all with a simple, cost-effective upgrade.
What is RdSAP and Why Does it Matter?
RdSAP (Reduced Data Standard Assessment Procedure) is the methodology used to measure and rate the energy performance of existing homes. It establishes Energy Performance Certificates (EPCs) and is central to schemes aimed at improving energy efficiency in UK homes.
Recognition within RdSAP means Kelda’s showers can now directly influence EPC ratings by reducing a home’s energy demand. That makes our technology not just a smart environmental choice, but also a strategic asset for homeowners, landlords, housing associations and developers aiming to improve their properties’ energy efficiency.
Why Was Kelda Recognised?
Unlike other low-flow showers that often compromise the shower experience, Kelda’s technology delivers a high-quality shower, using air to deliver a full, high-pressure experience whilst cutting water use by up to 55%.
Less hot water means less energy used – and that translates to lower carbon emissions and lower energy bills for residents.
What Are the Benefits?
For homeowners, this means lower utility bills and improved EPC scores. For landlords and housing providers, it supports compliance with tightening energy efficiency standards and decarbonisation targets. And for developers, it offers a low-disruption, future-ready solution for sustainable building.
Not only are Kelda reducing water and energy use, but we are also supporting the UK’s transition to net-zero housing.
