Definition

In an APC context, technical standards for inclusive surveying practice are the formal instruments, comprising British Standards, building regulations and international codes, that specify design criteria, dimensions and performance requirements for accessible and inclusive built environments. In the UK, the primary technical standards are Approved Document M (statutory guidance under Part M of the Building Regulations 2010) and BS 8300-1:2018 and BS 8300-2:2018 (Design of an Accessible and Inclusive Built Environment). The UN Convention on the Rights of Persons with Disabilities (CRPD), ratified by the UK in 2009, sets the overarching human rights framework within which these domestic standards operate.

Why this matters for Inclusive Environments

  • Level 1 knowledge: you must name the principal UK technical standards for inclusive design and explain what each covers.
  • Many RICS members work on cross-border projects where different technical standards apply; assessors expect candidates to know that Approved Document M and BS 8300 are UK-specific.
  • Applying the wrong standard on an overseas project, or assuming UK standards apply globally, constitutes a competence failure under Rule 2 of the Rules of Conduct.

Key principles

UK standards: Approved Document M and BS 8300

Approved Document M has two volumes: Volume 1 covers dwellings (M4(1), M4(2) and M4(3) categories); Volume 2 covers non-domestic buildings. BS 8300-1:2018 covers the external environment; BS 8300-2:2018 covers the internal environment with specific dimensions, colour contrast requirements and hearing enhancement guidance. Approved Document M sets the legal minimum; BS 8300 provides the best-practice benchmark and can acquire legal force through planning conditions or contractual requirements.

International standards

Internationally there is no single equivalent to Approved Document M. The United States uses the ADA Accessibility Standards; Australia uses the Disability (Access to Premises) Standards 2010. ISO 21542:2021 provides international guidance increasingly referenced on cross-border projects. RICS members working overseas should always identify the applicable local standards before referencing any UK document.

How to use technical standards in practice

Technical standards are reference documents, not checklists. On a UK project, identify the relevant sections of Approved Document M and BS 8300 for the building type; check dimensions and criteria against the proposed or as-built design; note deviations; and advise on remediation in priority order. On overseas projects, identifying the local standard is the essential first step. Standards should always be read alongside the Equality Act 2010, planning law and building regulations rather than as standalone documents.

Relevant RICS guidance and legislation

  • Building Regulations 2010, Part M and Approved Document M (Volumes 1 and 2) — the UK statutory baseline for accessible design.
  • BS 8300-1:2018 and BS 8300-2:2018 — British Standards covering external environments and buildings respectively; the UK best-practice benchmark.
  • Equality Act 2010 — the legal framework within which UK technical standards operate; the reasonable adjustment duty applies regardless of technical standard compliance.
  • ISO 21542:2021 — international standard on accessibility and usability of the built environment; useful on cross-border projects.
  • UN Convention on the Rights of Persons with Disabilities (CRPD) — overarching human rights framework, ratified by the UK in 2009.
  • RICS Rules of Conduct (effective 2 February 2022) — Rule 2 (competence) requires candidates to apply the correct standards for their jurisdiction.

Ethics and Rules of Conduct angle

Rule 2 requires members to act within their competence and keep their knowledge current. BS 8300 was significantly revised in 2018 and Approved Document M has been updated since its original publication; a member who relies on an outdated version, or applies UK standards on an overseas project without checking local requirements, breaches their competence obligation. Rule 4 (respect) also applies: technical standards exist because user needs are real and exclusion causes real harm.

APC-style Q&As

Q (Level 1)What are the two principal technical standards for inclusive design in England, and what does each cover?

Approved Document M (statutory guidance under Part M of the Building Regulations 2010) sets the legal minimum for accessible design. BS 8300, comprising BS 8300-1:2018 (external environment) and BS 8300-2:2018 (buildings), provides best-practice guidance with more detailed criteria. Together they form the UK two-tier framework for inclusive design.

Q (Level 1)Does BS 8300 have legal force?

Not directly. BS 8300 is a British Standard, not a statute. However, it can acquire legal or contractual force when imposed as a planning condition, specified in a building contract or required by a lender as a funding condition. In those cases, departure without justification can have legal and financial consequences.

Q (Level 2)You are advising a UK developer on a project in Dubai. Can you apply Approved Document M and BS 8300?

Not directly, as both are UK-specific. In Dubai you would first identify the applicable local accessibility standards. Where local standards are less comprehensive, you might reference BS 8300 or ISO 21542:2021 as best-practice benchmarks, making clear they are not locally mandatory, and document the standards applied.

Q (Level 2)What is ISO 21542 and when would you use it?

ISO 21542:2021 is an international standard on accessibility and usability of the built environment. You would use it on projects in jurisdictions without comprehensive local accessibility standards, on cross-border projects needing a common reference framework, or when advising clients who want internationally recognised best practice beyond any domestic minimum.

Q (Level 3)You are conducting an access audit of a large public sector office in England. How do you structure it and which standards do you apply?

(example) On a recent audit I used BS 8300-1:2018 for the external environment (approach, car parking, surfaces, signage) and BS 8300-2:2018 for the building interior (entrances, circulation, sanitary accommodation, hearing loops). I checked against Approved Document M Volume 2 for regulatory non-compliances and considered the Equality Act 2010 reasonable adjustment duty for features that might need addressing even if compliant at construction. The report categorised findings as: regulatory non-compliance requiring immediate action; departures from BS 8300 recommended as priority improvements; and longer-term enhancements. I advised the client to review the position annually as the Equality Act duty is ongoing.
