A passive fire protection handover pack should give the client, principal contractor and building manager clear evidence of what has been installed, where it is installed, which tested systems were used and what needs to be maintained. For commercial projects, getting that evidence ready before practical completion avoids last-minute disputes, weak building safety records and expensive return visits.
On London and UK commercial projects, passive fire protection is often hidden behind ceilings, risers and finished walls by the time a building is occupied. That makes the handover pack more than admin. It becomes the record that proves compartmentation has been considered, installed and documented properly.
Practical completion is the wrong time to discover that key penetrations, fire-rated walls or structural protection details were photographed inconsistently, labelled poorly or signed off by people who are no longer on site. The earlier the evidence pack is built, the easier it is to verify work while areas are still accessible.
This is especially important where a project must support dutyholder responsibilities under the Building Safety Act 2022, future inspection regimes and, for higher-risk buildings, the principles behind GOV.UK guidance on the golden thread. Even where a building is outside the higher-risk regime, good records help responsible persons, facilities managers and insurers understand what has actually been delivered.
A good pack should be specific enough for someone who did not attend site to locate, understand and maintain the installed protection. For most commercial fit-outs, refurbishments and new-build packages, that means including:
Midsummer’s passive fire protection services and fire stopping contractor support can help project teams plan this evidence from the start, rather than trying to reconstruct it after ceilings are closed.
The most common problem is not that no evidence exists. It is that the evidence is too vague to be useful. A folder of unlabelled photos does not show exactly which wall, riser or service penetration was protected. A product certificate without a location record does not prove the right system was installed in the right place.
Each photo should link back to a drawing reference, room, gridline, riser, floor level or asset ID. If the record cannot be matched to a location, it will be hard to rely on later.
Fire stopping is system-based. The product, substrate, aperture size, services, annular gaps and installation method all matter. Records should show the tested detail used, not just the brand of material.
Once ceilings, cupboards, riser doors and finishes are installed, inspection becomes slower and more disruptive. A planned fire stopping site survey during the works can identify gaps before they become handover pain.
The best approach is to treat the evidence pack as a live project deliverable, not a close-out chore. Agree the required format at pre-start, capture evidence by area as the work progresses and review it regularly with the principal contractor or client team.
For live buildings and phased refurbishments, this discipline also reduces disruption. If a facilities team later needs to review compartmentation, clear records make the process faster and less invasive.
Quality records start with correct installation. A competent fire stopping installation process should consider the substrate, service type, required fire rating and compatibility of tested details before materials are applied. The handover pack then captures that work in a way the client can retain.
Project teams should also cross-check expectations against relevant statutory guidance such as Approved Document B and the role of the Building Safety Regulator where building safety duties apply. These resources do not replace project-specific design advice, but they help frame why accurate records matter.
If the answer to any of these is unclear, the project is carrying avoidable handover risk. Midsummer’s guide to fire stopping evidence packs explains how building managers can keep those records useful after occupation.
Midsummer Fire Protection supports contractors, commercial property teams and building managers with certified passive fire protection, fire stopping surveys, installation and documentation support across London and the UK. If you need fire stopping delivered with clear evidence for handover, contact Midsummer to discuss the project requirements.
It is a structured set of drawings, photos, product information, tested system references, inspection records and sign-off documents showing what passive fire protection work was completed and where.
It should start before installation begins, with evidence captured throughout the works. Waiting until practical completion usually creates gaps because key areas may already be concealed.
The formal golden thread requirements apply to higher-risk buildings, but the underlying principle is useful on most commercial projects: keep accurate, accessible information about safety-critical work.
The client, building owner, responsible person or facilities management team should retain the records so future maintenance, refurbishments and inspections can be managed safely.
