In short: Affordable new-build rentals in London come from three main sources: build-to-rent blocks run by professional landlords, discount market rent homes (often around 20% below market) offered with income criteria, and new-build flats let by private landlords. New homes usually have better energy ratings, which lowers bills.
| Type | How it works | Good to know |
|---|---|---|
| Build-to-rent | Whole block owned and managed by one landlord | Gyms, lounges, on-site teams; longer tenancies |
| Discount market rent | Rent set below market for eligible households | Income caps and local eligibility rules |
| Private landlord new-builds | Individual owners letting flats | Wider choice; check service levels |
