Salary: Starting salary from £52,344 per annum

Location: London, EC4R 9AB/Hybrid

Closing Date: 02 April 2026

Warmer Homes London, launched by London Councils and the Mayor of London, is tackling the systemic barriers preventing retrofit at scale—focusing on social housing, low-income homeowners and private renters most vulnerable to fuel poverty.

We’re looking for a Design Researcher to help us test, learn and improve how retrofit programmes are delivered across London.

The role

Working within a multidisciplinary data, design and delivery team, you’ll run research, prototyping and pilots that generate real evidence about what works in large-scale retrofit programmes.

You’ll:

• Design and run mixed-methods research with residents, boroughs and delivery partners
• Translate insights into prototypes, service mock-ups and pilot tests
• Support a “test and learn” approach to improving retrofit programme delivery
• Produce clear, compelling insights and recommendations for senior decision-makers
• Develop artefacts such as journey maps, service blueprints and opportunity maps

We’re looking for someone who:

• Has strong qualitative and quantitative research experience
• Can turn complex findings into clear narratives that influence decisions
• Is comfortable working in fast-paced, experimental environments
• Enjoys collaborating with designers, analysts and delivery teams
• Work on one of the largest retrofit programmes in England
• Help shape how London delivers warmer, greener homes at scale
• Be part of a purpose-driven team tackling fuel poverty and climate change
