Fire stopping guidance in Scotland differs from England. Building work is governed by the Building (Scotland) Regulations 2004, supported by technical handbooks, and building warrants come from the local authority verifier. For owners, FMs and contractors working on non-domestic buildings in Scotland, this article summarises what the handbook says about sealing service penetrations. It is general guidance, not a substitute for the handbook or professional advice.
The handbook and compartmentation
Section 2 of the non-domestic Technical Handbook deals with fire. Its compartmentation guidance, under standard 2.1, is about dividing buildings so fire and smoke are contained. You can read it on the Scottish Government’s Technical Handbook 2022 (non-domestic) 2.1 page. Compartment walls and floors are only as effective as the seals around the services that pass through them.
What clause 2.1.14 says, in brief
Clause 2.1.14 says service penetrations should be fire stopped to provide at least the fire resistance duration of the wall or floor they pass through. It also says proprietary fire-stopping products, including intumescent products, should be tested for their end use. In plain terms, the seal around a pipe or cable must hold for as long as the wall or floor around it, and the product must have test evidence for the way it is actually used.
Why end-use testing matters
A product tested in one situation is not proven in another. A seal is only as good as its match to the tested detail: the same product, substrate, service type and size, gap, depth, backing and orientation. A sealant tested around a steel pipe in a masonry wall may have no evidence for a plastic pipe in a plasterboard partition. Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. See fire-rated vs intumescent sealant.

Roles on a Scottish project
The designer specifies the fire-stopping solution. The verifier deals with the building warrant and completion. The installer installs what is specified, to the product’s tested detail. For existing buildings, the owner or responsible person manages fire safety in use, often with a fire risk assessor. Where fire-rated sealant is the specified product, we install it to the manufacturer’s tested detail, and we’ll tell you if the detail calls for something else, such as a collar or batt.
On larger projects, a fire engineer may advise the design team, and the main contractor will coordinate trades whose work passes through compartment walls and floors. Clear responsibility for each penetration avoids gaps being left between trades.
Practical points for Scottish estates
- Check for new services through compartment walls after fit-outs and M&E works.
- Keep records of seals, products and details with photos.
- On older buildings, including sandstone tenements in Glasgow and Edinburgh or granite buildings in Aberdeen, check the asbestos information before disturbing old materials.
- On listed buildings and in the Edinburgh Old and New Towns World Heritage Site, take advice before visible works.
Our post fit-out checklist applies in Scotland too.

Quick answers
Does Approved Document B apply in Scotland?
No. Approved Document B is guidance for England. In Scotland, the Building (Scotland) Regulations 2004 and the technical handbooks apply.
Must fire-stopping products be tested in Scotland?
The non-domestic handbook says proprietary fire-stopping products, including intumescent products, should be tested for their end use.
Who approves fire stopping on a Scottish project?
The designer specifies it and the local authority verifier deals with the building warrant and completion. Installers work to the specified tested details.
Does clause 2.1.14 apply to existing buildings?
The handbook gives guidance on meeting the building regulations when building work is carried out. For an existing building in use, take advice from your fire risk assessor on what is needed.
