Social landlords have more than 6,400 Passivhaus homes in development

The landlord currently building the highest number of Passivhaus homes was the London Borough of Hounslow. It has plans to develop 967 homes built to the standard as part of its Convent Way scheme, which equates to 15% of the total Passivhaus development pipeline in this dataset.

The local authority told Inside Housing that the 967-home scheme is yet to receive planning permission, but an application has been submitted.

Hounslow was followed by Newham Council, which has 600 Passivhaus homes in development across nine schemes. 

Newham has been approached for comment.

In third place was Lancaster City Council, which is building 440 Passivhaus homes on the Mainway Estate.

Caroline Jackson, leader of Lancaster Council, said: “We are committed to supporting the delivery of high-quality and energy efficient housing as part of our wider efforts to build a more sustainable future.

“By investing in low-energy homes, we will help to cut carbon emissions, reduce fuel bills for residents, and create healthier, more resilient communities.

“We look forward to progressing our plans further once funding from Homes England is unlocked.”

The housing association with the most Passivhaus homes in development was Queens Cross Housing Association, which is building 314 homes at Cedar Court in Glasgow.

The Passivhaus Trust explained that the data is subject to changes because some projects start out with an aim to reach the energy efficiency standard, but plans could be amended during construction.

Of the 1,740 Passivhaus homes already completed by landlords between 2010 and 2024, the biggest project was Greenhaus in Salford by Salix Homes and the English Cities Fund, which delivered 96 Passivhaus-certified flats and maisonettes.

In May, house builder Barratt London announced plans to build 728 Passivhaus homes in the capital, including affordable homes.
