Most retrofit isn't bad. But the gap between "okay" and "great" can mean a colder home, condensation, or wasted spend.
So what does good retrofit actually look like? Here are the five things you should expect from anyone working on your home, whether you're a homeowner, a council procuring at scale, or a community group planning a programme.
1. A whole-home assessment before anyone quotes
2. Whole-house thinking, not a single measure
3. A named Retrofit Coordinator overseeing the work
4. Certified, vetted, accountable professionals (MCS, TrustMark)
5. A ventilation strategy designed in, not bolted on
RetrofitWorks is a co-operative of certified retrofit professionals delivering schemes across the UK. We exist because retrofit at scale only works if quality scales with it.
