Fire door peephole

Updated: October 2026

A flat entrance door sold as FD30 or FD60 is not a house door you can finish with any spy hole from the shelf. A fire door peephole is allowed only when that viewer is inside the doorset’s evidence and fitted the way that evidence describes. A title that says fire proof does not do that job. This page is the stop-or-go check before anyone drills. The twelve listings are on the [door viewer comparison](/hub/door-and-window-security/door-viewer). Peter F. used GOV.UK, a named doorset manual, and the amazon.co.uk files saved on 19 October 2026. This is not a lab test. A qualifying purchase can earn a commission at no extra cost to you.

The doorset is the approval, not the peephole title

GOV.UK’s Approved Document B FAQ treats a fire doorset as the whole assembly, including the ironmongery. Once someone cuts a hole, the peephole is part of that assembly. The same diameter can be inside one doorset’s evidence and an untested alteration on the next. Three Bwintech listings, about £6.99 and about £7.49, say UL listed and fire proof. The review text is one shared block, and a UK review says there is no fire-rated certificate a leaseholder could show a landlord. The 4.3 from 332 reviews is not a fire test. If the certificate does not name a viewer, stop.

TS 002, intumescent, and a named test

DHF TS 002:2009 is a UK performance specification for door viewers. The NBS record describes the classification, tests, and marking written because there was no official standard. It does not prove that every viewer carrying those words is acceptable in every 30-minute or 60-minute door. The doorset evidence still has to name the viewer. Secured by Design’s record for UAP, and Rutland’s own statement of TS 002 plus BS EN 1634-1 and BS EN 1634-3, are not ASINs in this twelve. Falcon’s 60-minute manual names a UAP 12 mm and a Glutz 15 mm viewer, with tested intumescent mastic. A 14 mm or 16 mm retail barrel is not those parts. Stoppwerk’s glass comments are not an FD30 certificate.

What to ask before you drill

The person who confirms the viewer is the door manufacturer, or the party who holds the doorset evidence, not the marketplace seller. Ask which doorset is installed, whether a viewer is named, which diameter is allowed, and whether intumescent is required. If the reply is an amazon.co.uk title, that is not the certificate. Older Secured by Design guidance for flat entrance doors, from the PAS 24:2007 era, places a viewer about 1,200–1,500 mm from the bottom. That is a placement note, not permission to drill.

A camera hole is still an alteration

The EZVIZ DP2C, at about £95.41, wants a hole of 16.5–50 mm. Enlarging a 12 or 14 mm spy hole is still a doorset alteration. A stated range of 35–105 mm is not a fire-door approval. The camera fork is on peephole camera vs door viewer. When the evidence does name a viewer, fit that named body, tolerance, and intumescent product. A house door with no fire certificate is outside this page. Ordinary measurements are on the door peephole buying guide.

Common questions

Can I drill a fire door for a peephole?
Only when that peephole is already inside the doorset evidence, and only in the way that evidence describes. GOV.UK’s Approved Document B FAQ treats the doorset as the whole assembly, including ironmongery. A new hole the certificate does not name is an untested change. If you cannot point to the named viewer, do not drill.
Does UL listed on Amazon mean FD30?
No. UL listed on a Bwintech title is a marketplace claim, and the shared UK review file says there is no certificate a leaseholder could show a landlord. FD30 and FD60 describe the doorset, not a badge in a product title. The shared 4.3 from 332 reviews does not record a fire test of your door.
What is DHF TS 002?
DHF TS 002:2009 is a UK performance specification for door viewers, covering classification, tests, and marking. The NBS record notes it was written because there was no official standard. It does not mean every viewer that mentions TS 002 is acceptable on every FD30 or FD60 door. The doorset evidence still has to name the viewer.
Does the viewer need an intumescent liner?
It needs one when the doorset evidence says so. Falcon’s 60-minute manual, for the viewers it names, calls for tested intumescent mastic and a hole within 1 mm of the body. Rutland states intumescent on its own tested viewer. A retail listing here that never mentions intumescent is not supplying that detail.
Who confirms the viewer is allowed?
The door manufacturer, or the party who holds the certificate, which for a flat is often reached through the managing agent. The amazon.co.uk seller confirms what is in the parcel, not whether your FD30 doorset was tested with that barrel. A title that says fire proof is the question, not the answer.
What should a leaseholder ask the managing agent?
Ask which fire doorset is fitted, whether a viewer is named in the evidence, which diameter and product are allowed, and whether intumescent material is specified. Ask who may do the work, and what happens if the leaf is drilled outside that evidence. Keep the reply with the lease paperwork. An older PAS 24:2007-era note places a viewer about 1,200–1,500 mm from the bottom, and that height is not permission to cut.
