About Us

GreenResi offers expertise and software to help institutions to future-proof and grow residential portfolios.

Our clients range from Local Authorities who need to buy lots of homes quickly to meet urgent Temporary Accommodation needs through to investors who need to minimise costs and environmental risks in their existing portfolios. 

What they have in common is a need to make efficient, reliable decisions on lots of residential properties without the hassle of traditional, manual acquisition and management processes. 

We're sector experts with a bold vision: an environmentally, socially and financially sustainable UK housing market. 

To discuss how we can help, book a call.
