What Is a Retrofit? Why It Matters for Sustainable Living in 2025
The word 'retrofit' is everywhere in 2025 — from government grants to landlord guides. But what does it actually mean, and why should residents care? Whether you rent or own, retrofitting your home is one of the biggest steps you can take toward lower bills, better comfort, and a more sustainable future.
Retrofit: The Simple Definition
A retrofit means improving an existing property by installing modern energy-efficient features — without knocking it down or starting over. Think insulation, ventilation, new heating systems, and solar panels — all designed to make older buildings work like modern ones.
Why Retrofitting Matters Now
Most homes in the UK were built before 1990 — and many leak heat, burn more fuel, and are expensive to run. Retrofitting can cut energy use by 60% or more, making it crucial for hitting the UK’s net zero targets.
Common Retrofit Measures in 2025
- Loft and cavity wall insulation
- Smart electric heating or heat pumps
- Mechanical ventilation with heat recovery (MVHR)
- Triple glazing and airtight sealing
- Solar panels with battery storage
Can You Retrofit If You Rent?
Landlords are legally responsible for structural improvements — but tenants can request retrofits and raise issues flagged by EPCs or damp/mould reports. Property Krowd helps residents understand their retrofit options and how to raise them with landlords or councils.
