Resident Voices
These are a few of the stories our Citizen Scientists heard directly from residents.
Lewisham Retrofit Hub
Resident Voices
One resident described her installation as unremarkable, and meant it as a compliment. The team called the week before. They called the day before. They arrived on time, introduced themselves, explained what they would do and how long it would take. At the end of the day they showed her how the new windows worked and cleaned up.
On a nearby estate, another resident praised a window installer who asked to borrow her hoover before he left. What stayed with her was the accumulation of small things done right: being asked in advance about each stage; having a leak dealt with immediately; and clear communication throughout.
Our Citizen Scientists collected many stories like these. But some stories showed us where we need to do better. Below are a few examples we think are worth sharing, about the wide range of experiences people have had on past retrofit programmes. To protect people's privacy, each portrait draws on more than one resident's experience - the details are real, but combined so no individual can be identified.
Portrait 1: Warm for the first time in fifty years
One resident had lived in his Lewisham home for almost fifty years. Every winter he sat in his armchair under a throw, too cold to take it off even while watching TV.
After cavity wall insulation was fitted, the next winter was different. For the first time in decades, he was turning his radiators down, not up. He called it amazing – not a word he used lightly.

| How does cavity wall insulation work? Most walls built after 1920 have two layers with a small gap between them. Cavity wall insulation fills that gap with a material that slows heat from escaping. Most residents who had it fitted noticed the difference in the first cold winter. |
Portait 2: The £80 a month she had not expected
One resident had solar panels fitted, and for a long time, she did not know how to use them. Nobody had explained which appliances to run during daylight hours (roughly 9am to 4pm) or that she needed to register with her energy provider after installation.
When someone finally sat down and explained it, she started shifting her habits. She estimated she was saving around £80 a month.
Her experience was not unusual. Going forward, every resident will get a full explanation of any new system before the installation team leaves.

Portrait 3: The relationship that made the difference
Among residents who had an RLO they trusted, the experience of retrofit was transformed for the better. One resident called her RLO over and over again during a difficult stretch – contractors not arriving, problems not being dealt with.
The RLO always picked up. Always passed the message on. Always stayed calm when the resident understandably could not.
Now, every resident is assigned a named RLO from the moment work is confirmed.

Portrait 4: The fan that nobody explained
When a continuous ventilation fan was installed in one resident’s home, it ran through the night. She had not been told it would do this. She reported it as a fault.
A contractor came and switched it to manual mode, which stopped the noise but also stopped the fan from working properly. It took three visits before someone finally explained what the fan was designed to do.

| Why does the fan run all the time? If a continuous ventilation fan has been installed, you may notice it running even when you have not switched it on. This is normal and on purpose. The fan measures how much moisture is in the air. When it is high enough to risk damp or mould, the fan runs. When the air is drier, it slows down. It uses very little electricity. It should sound like a quiet hum in the background. If it sounds different, or runs at full speed without stopping, that is when to contact your RLO. In Wave 3, a plain-language guide to any new system is a required part of every handover. |
Portrait 5: The first winter without mould
One resident had painted over mould in her bedroom every year for as long as she could remember. She had tried sprays. She had tried opening windows. Nothing worked for long.
After insulation and ventilation were installed, the mould did not come back the following winter. It was, she said, the first winter in years that it had not.

| How can retrofit help prevent damp and mould? Damp and mould are caused by too much moisture in the air with nowhere to go. In poorly insulated homes, that moisture settles on cold surfaces (walls, windows, ceilings) and mould follows. Retrofit tackles this in two ways: insulation raises wall temperatures, so condensation is less likely to form, and better ventilation gives moisture a way out. From October 2025, social landlords are legally required to investigate and fix dangerous damp and mould within set timeframes under Awaab’s Law. Where damp or mould is found during an assessment, fixing it comes first, before any retrofit work begins. |
