The Challenge

Safe, secure and affordable

Sovereign housing provides great, wonderful homes having 60,000 properties across Southern England. It’s crucial to Sovereign Housing that their properties are safe, secure and affordable to run.

Old inefficient fossil fuel solutions

Some of their houses are 50 years old, meaning that when reviewing the fabric of the building, often extra insulation or replacement windows are needed, therefore, when looking at heating there are a number of properties that have old inefficient fossil fuel solutions. This consequently gives the challenge to Sovereign of finding an affordable, efficient and eco friendly heating system for their residents.

The Requirement

New and existing homes

Sovereign have installed their ‘Homes and place’ strategy. The strategy is about investing into their existing homes and building new ones.

Carbon neutral 2050

It’s also about ensuring the properties are energy efficient with having a goal by 2050 to have all their properties meeting that standard and be carbon neutral.

The Solution

Ecodan air source heat pumps

A number of Sovereigns housing are rural properties located in ‘off-gas’ areas. This is where Ecodan steps in as the perfect product.

How does a heat pump work?

They work through harnessing energy from the outside air and converting this into heating and hot water for the property. The benefit that Ecodan brings to housing associations is the running costs, not only for the housing association but also for the residents.

£700 annual saving

Anne and Alan, Sovereign Housing residents had an Ecodan unit installed to their property replacing their night storage heaters that they struggled to afford. Ecodan has helped the couple save a significant amount on their heating, saving approximately £700 a year on their electric bill whilst gaining more heat and comfort.
