MHCLG consults on fire protection rules for telecoms work in buildings

MHCLG: Fire protection and building control dispensations

A government consultation proposes streamlined building control procedures for certain telecommunications work while retaining fire protection requirements.

The Ministry of Housing, Communities and Local Government (MHCLG) has opened a consultation on dispensations covering drilling holes through internal fire-resisting walls for fibre optic cabling and work to mobile communications masts.

The proposals focus on work to existing buildings, including existing higher-risk buildings, and also seek views on approval routes for fibre optic work in buildings outside the higher-risk regime.

The consultation document describes the higher-risk building control regime introduced in October 2023 and defines higher-risk buildings as buildings containing at least 2 residential units, care homes and hospitals that meet the 18 metre or seven storey height threshold.

How the higher-risk process would change

The consultation outlines that the Building Safety Regulator (BSR) is the sole building control authority for higher-risk building work in England.

For fibre optic cabling in existing higher-risk buildings, the proposal is to dispense with procedural requirements linked to gateway two, requirements during construction and gateway three, so work could proceed without applications to, or approval from, the BSR.

A condition under consideration is written notification to the BSR once the work is completed, alongside retaining a handover of accessible digital information covering how the work complies with parts B, F, L and O of Schedule 1 of the Building Regulations 2010.

For fibre optic cabling in existing buildings outside the higher-risk regime, the proposal is to dispense with procedural requirements related to giving a building control notice or submitting full plans, with a completion notification to the relevant building control authority also under consideration.

For mobile communications masts on existing higher-risk buildings, the proposal is to dispense with gateway two and construction-stage procedural requirements, while retaining gateway three checks including the need to apply for, and obtain, a completion certificate from the BSR.

Across the proposals, conditions under consideration include limits on hole size, fire-stopping requirements, product safety standards, time limits between start and completion and requirements for relevant qualifications, with the Principal Contractor identified as the party responsible for ensuring conditions are met.

Consultation dates and response route

The consultation runs from 27 January to 24 March 2026 and invites evidence and views on scope, conditions, enforcement and whether competent person schemes could be appropriate in future for the types of work covered.
