When Heritage Meets Fire Safety: The Listed Building Dilemma

There are roughly 400,000 listed buildings in England. If you manage property in any of our historic city centres; Manchester, Leeds, Liverpool, Sheffield, London; there's a good chance some of your portfolio sits on that list.

And if it does, you've got a compliance problem that most fire risk assessments don't fully address.

The conflict

Fire safety law requires FD30 or FD60 doors, intumescent strips, smoke seals, self-closing devices. The Regulatory Reform (Fire Safety) Order 2005 and the Building Safety Act 2022 don't make exceptions for old buildings.

But listed building consent law doesn't make exceptions for fire safety either. Replacing an original door, adding visible intumescent seals, even swapping out door furniture; all of it can count as an unauthorised alteration to a building's special interest.

Do the work without consent, and you're not just risking a fire safety enforcement notice. You're risking a criminal offence under the Planning (Listed Buildings and Conservation Areas) Act 1990.

Most people don't realise both rules apply at once.

The way through

Historic England's own guidance is clear: this isn't usually an either/or. Most historic doors can meet fire resistance standards without full replacement, through:

• Recessed intumescent seals instead of surface-mounted strips

• Upgrading the door core from the rear face, invisible from the principal side

• Retaining original ironmongery, supplemented rather than replaced

The sequence matters too. Establish the listing grade. Talk to the conservation officer before specifying works. Where consent is needed, pair the fire risk assessment with a heritage justification showing you considered the less destructive option first.

Why this matters for property managers

If your fire door survey doesn't flag listed status, you could be walking into:

• Remedial works that trigger a heritage breach

• Delays when consent surfaces mid-project

• A false sense of compliance; fire-safe on paper, legally exposed in practice

A proper survey should tell you not just what needs upgrading, but what additional consent that upgrade requires; before you commission the work, not after.

Fire Door Surveys Ltd carries out fire door inspections and compliance surveys across Manchester, Liverpool, Leeds, Sheffield, and London. Get in touch if your portfolio includes listed or conservation-area properties; we'll flag the heritage considerations alongside the fire safety ones.
