The Building Safety Act 2022 (BSA 2022) creates a new regulatory regime for 'higher-risk buildings' — residential buildings over 18 metres or 7 storeys in England. It establishes the Building Safety Regulator, introduces the 'accountable person' framework, requires a Golden Thread of building information, and restricts the ability of building owners to pass cladding remediation costs to qualifying leaseholders.

Key obligations

Higher-risk buildings must be registered with the Building Safety Regulator. Failure to register is a criminal offence. The accountable person has ongoing duties: Golden Thread maintenance, residents' engagement strategy, Building Safety Case Report, and compliance with remediation orders.

Higher-risk buildings — 18m / 7 storeys

  • Buildings with at least 2 residential units that are at least 18 metres tall or have at least 7 storeys are 'higher-risk buildings'
  • The accountable person (AP) is the entity controlling the common parts — typically the freeholder or resident management company
  • The AP must register the building with the Building Safety Regulator and maintain a Golden Thread of building information
  • Failure to register is a criminal offence. Unregistered buildings can be prohibited from occupation

Cladding remediation and leaseholder protections

  • Qualifying leaseholders (owned flat on 14 February 2022) are protected from certain remediation costs being passed via the service charge
  • Remediation orders: the First-tier Tribunal can require the building owner to carry out remediation works
  • Remediation contribution orders: developers or landlords can be required to contribute to remediation costs
  • Ground 6A (Renters' Rights Act 2025): mandatory possession ground where a remediation order applies and works cannot safely proceed with tenants in occupation. Notice: 4 weeks

Fire Safety Act 2021 — additional obligations

  • FRA must now cover flat entrance doors, external walls (including cladding), and balconies
  • Buildings over 11m: monthly lift checks, quarterly fire door checks
  • Buildings over 18m: evacuation plans, residents' engagement strategy, Building Safety Case Report

Frequently asked questions

I own a flat in a block over 18m — am I the accountable person?+

Almost certainly not. The accountable person is the entity controlling the common parts — usually the freeholder, head leaseholder, or resident management company. Individual flat owners are not normally the accountable person unless they own the freehold or control the structure.

What is Ground 6A and when can I use it?+

Ground 6A is a new mandatory possession ground (Renters' Rights Act 2025) for landlords whose property is subject to a remediation order or contribution order under the Building Safety Act 2022 where works cannot safely be carried out with tenants in occupation. Notice period: 4 weeks. No 12-month tenancy requirement applies.
