Areas we cover: south-east London and north-west Kent

• Greenwich: Victorian terraces, conservation areas and riverside flats
• Bexley: interwar semis, early cavity walls and extensions
• Thamesmead: concrete and system-built homes, later brick houses and new flats
• Lewisham: solid-walled terraces, converted flats and cottage estates
• Dartford: Victorian terraces, post-war houses and new-build estates

Solid-walled terraces. Common across Greenwich, Lewisham and older parts of Bexley and Dartford. These walls need to manage moisture, so insulation materials and detailing matter.

Interwar semis. Found throughout Bexley, Eltham and parts of Dartford. Many have early cavity walls that may or may not be suitable for filling, plus bays and extensions.

Post-war and system-built homes. Thamesmead and estates across the area include concrete and system-built homes, where cold bridges and condensation are common concerns.

Converted flats. Many Victorian houses in Lewisham and Greenwich are now flats, where shared walls, roofs and consent from the freeholder shape what can be done.

Newer homes. Recent developments in Dartford, Thamesmead and Greenwich Peninsula are already well insulated, so the focus moves to heating, hot water and ventilation.

Wherever you are, the process is the same. We start with a conversation about the property and your goals, then visit to carry out a retrofit assessment. We check moisture and ventilation risk for each possible measure, and write a medium-term improvement plan setting out what to do, in what order and why. We can then help you brief installers and review their proposals against the plan.

Projects are led by Oluwafemi Adeoye, a Level 5 qualified Retrofit Coordinator who also trained as a Retrofit Assessor. He also holds the City & Guilds Level 4 Non-Domestic Energy Assessor qualification and is an Elmhurst-accredited non-domestic energy assessor for commercial EPCs. You deal directly with the person who visits your home and writes your plan.
