Government planning guidance on build to rent has been updated, with a fresh revision to the section on affordable private rent. For most small landlords this is not a day-to-day letting rule, but it is still worth understanding because build to rent is now a major part of the private rented sector and can shape local rental supply, competition, tenant expectations and planning decisions.
The GOV.UK guidance describes build to rent as a distinct asset class within the private rented sector. It is aimed mainly at local planning authorities, developers and institutional landlords, but the policy choices it sets out can affect the rental market around smaller portfolios too. Where councils encourage larger professionally managed rental schemes, landlords nearby may see changes in local supply, amenity standards, rent comparables and tenant choice over time.
The update published on 8 May 2026 concerns affordable housing within build to rent schemes. The guidance says affordable housing on these schemes should, by default, be provided as affordable private rent, with affordable and market rent homes managed together by a single build to rent landlord.
What the updated guidance says
The guidance keeps the benchmark that 20% is generally a suitable level of affordable private rent homes in a build to rent scheme, unless a local authority justifies a different approach through evidence in its local plan or a developer makes a viability case. It also says national affordable housing policy requires a minimum 20% rent discount for affordable private rent homes compared with local market rents.
The revised paragraph adds detail on when the discount should be calculated. It says the discount should be worked out when a tenancy for the discounted home is granted, or when the rent is reviewed using the section 13 process. The rent on the discounted homes should then increase on the same basis as rent increases for market-rate tenancies within the development.
That matters because it links the affordable private rent calculation to the wider rent-setting process within a managed scheme. It also points readers to the government’s rent increases guidance, which many ordinary landlords will already recognise from wider tenancy management.
Why small landlords should pay attention
Build to rent policy can feel remote from the concerns of a landlord with one or two homes. However, these schemes can influence the rental market in practical ways. Large professionally managed developments often set visible standards for communal spaces, repairs processes, energy performance, digital tenant communication and predictable tenancy management.
They may also affect local rent evidence. If a significant number of newly managed rental homes arrive in one area, landlords reviewing rent levels or considering property improvements may need to look more carefully at what tenants are comparing against. The point is not to copy an institutional model, but to understand how local supply is changing.
For landlords considering future purchases, disposals or upgrades, the guidance is another reminder that rental markets are increasingly shaped by planning policy as well as individual landlord costs. It sits alongside wider pressures from tenancy reform, energy standards and supply constraints. Our recent piece on the housebuilding slowdown looked at why the broader supply picture can matter to landlords even when they are not developers.
Local plans are worth watching
The build to rent guidance says local planning authorities should use local housing need assessments to consider the need for different types and tenures of homes, including homes for people who want to rent. If a need is identified, councils should include a plan policy setting out how build to rent will be promoted and accommodated.
For landlords, that makes local plan consultations and major planning applications worth monitoring. A town-centre regeneration site, a large brownfield scheme or a new rental-led development can all change the balance of local supply. In some areas it may add much-needed homes and ease pressure. In others it may create a new professional competitor for tenants who value on-site management and modern amenities.
None of this means small landlords should make rushed decisions. It does mean that local planning news is not just a developer issue. It can become part of the evidence base for rent reviews, refurbishment planning and decisions about the type of tenant demand a property is likely to meet.
Keep the compliance angle separate
The updated build to rent guidance is not a new rule requiring small private landlords to provide affordable private rent. It is planning guidance for build to rent schemes and affordable housing provision within those schemes. Landlords should be careful not to confuse it with separate rules on rent increases, tenancy reform or property standards.
That said, it is another sign of how detailed rental policy has become. Landlords who want to stay ahead should keep separate files for different types of requirements: tenancy paperwork, rent review process, property condition, energy efficiency, local licensing and planning context. The same record-keeping discipline is useful for other current changes, including Renters’ Rights Act preparation.
A practical takeaway
Small landlords do not need to act on this update as if it were a new compliance deadline. The practical step is to watch how build to rent is being encouraged locally, especially where councils are consulting on local plans or approving large rental-led schemes.
If a major build to rent scheme is planned nearby, landlords may want to note the expected number of homes, target tenant group, amenities, management model and likely completion date. That information can help with realistic market comparisons and longer-term property planning.
