Building Regulations Inspector (Approved Inspector)

Building regulations inspectors — whether working as Registered Building Control Approvers (private approved inspectors, formerly known as Approved Inspectors under the Building Act 1984) or as local authority building control officers — check that building work complies with the Building Regulations 2010, ensuring that buildings are structurally sound, energy efficient, fire safe, and accessible. The role is a statutory quality assurance function underpinning the safety of the UK's built environment.

The work cycle follows the stages of building work: reviewing building notice or full plans submissions for regulatory compliance (structural calculations, fire engineering reports, drainage design, thermal compliance calculations), inspecting foundations, structural elements, fire compartmentation, insulation, drainage, and other regulated elements at construction stage, and issuing certificates of completion. Inspectors advise applicants, architects, and contractors on Building Regulations requirements, assess innovative construction methods against the regulations, and liaise with other statutory consultees (fire services, disability access advisers).

The Building Safety Act 2022 has significantly reformed building regulations oversight, particularly for higher-risk buildings (HRBs — buildings over 18 metres with two or more dwellings or certain other buildings). HRBs now require regulatory oversight from the new Building Safety Regulator (operating within HSE), creating new gateway and registration processes. Private approved inspector organisations must now be registered as Registered Building Control Approvers (RBCAs) with the Building Safety Regulator, and individual inspectors must hold the appropriate registered building inspector status.

Professional routes include the Chartered Association of Building Engineers (CABE) and RICS building control pathways, leading to Incorporated Engineer or Chartered Engineer status. The Level 4 Certificate in Building Control Practice (which has replaced the former Local Authority Building Control qualifications) is the entry-level professional qualification.

Building regulations inspection is a statutory requirement — every building project requiring regulations approval must be inspected, and without a completion certificate, properties cannot be sold or occupied in many circumstances. The Building Safety Act 2022 has increased rather than reduced the regulatory burden, creating new higher-risk building oversight requirements that demand more qualified building control professionals. The UK has a serious historic shortage of building control professionals — identified by the government as a constraint on housing delivery — and the Building Safety Regulator's new competency requirements are restricting supply further, increasing the value of qualified practitioners.

The housing crisis, infrastructure investment programme, and commercial property retrofit agenda all generate sustained building regulations inspection workload. The transition to Part O (overheating), the future homes standard (Part L revision), and the Approved Document B (fire safety) revisions following Grenfell are creating new technical complexity that requires more qualified inspectors, not fewer.

Morning: inspecting a new-build housing development at foundation stage — checking that strip foundations comply with the approved structural engineer's design, that depth and width are consistent with the Building Regulations Approved Document A requirements, and that the compressibility of the ground is consistent with what was assessed at the plans stage. You note that the cavity wall tie spacing on one section is incorrect and issue a holding notice to the site manager. Afternoon: plans checking a proposed change of use from commercial to residential — reviewing fire compartmentation proposals, means of escape, and compliance with Part M (accessibility). Late afternoon: telephone consultation with an architect on a proposed extension to a listed building, advising on Building Regulations exemptions and the relaxation process under Section 4 of the Building Act.
