Check whether you actually have a choice
The Building Safety Regulator is the building control authority for work within the higher-risk building regime. That is not an ordinary choice between the local council and a private approver. Establish the building's status before requesting competing quotations for the wrong route. [3]
For other work, the private organisation must be a registered building control approver. This terminology has applied since April 2024. Check the organisation separately from the individual registered building inspectors who will undertake restricted activities. [4] [5]
Understand the administrative difference
With council building control, the appropriate submission may be a full plans application or, where available, a building notice. Full plans provide a formal pre-construction plan decision. A building notice does not provide the same formal approval of a detailed design. [6]
A private approver begins through an initial notice submitted with the person intending to carry out the work. The council's acceptance of that notice is a procedural step, not a finding that every technical drawing is approved. Agree the actual design-review arrangements with the approver. [7] [8]
Compare the service you will receive
Ask each body to describe its proposed inspection stages, how much notice a visit requires, who answers technical queries and what happens when the usual inspector is unavailable. A council's published service commitment can be as relevant as a private company's sales description: Redbridge, for example, publishes both a charter and a booking procedure. [9] [10]
Also compare the treatment of amendments, extra visits, specialist input and incomplete work. A headline fee is not enough to establish that two offers cover the same project. Council fee information and the chosen body's written quotation should be read together with the scope. [11]
Consider continuity and completion
Ask how the project records will be maintained and what completion evidence will be needed. If a private approver cannot continue, a regulated transfer or reversion process may be necessary; appointing a replacement informally does not settle that process. [12]
The preferred route is the one whose lawful scope, capability and service arrangements fit the project. Building control is still a compliance-checking service rather than full-time supervision of the builder. Separate construction oversight should be defined separately. [13]
MHCLG's proposed changes to plan approval were still described as awaiting a response in its September 2026 circular. Do not treat the proposals as an already available new approval route. [14]
