Best door chains, security braces and portable door locks UK (2026)
A door chain lets you see who is calling before the door is fully open; a freestanding brace adds a removable extra layer behind a door you already lock; a travel lock adds a little privacy on an internal door away from home. None of them replaces a proper lock, and only one device here names a standard. We compare them on what the makers state, crediting every figure; we have not fitted or tested any of them. Whatever you choose, it must come off quickly from inside, because the door it holds shut is also your way out.

Our verdictOur verdictResearched Yale says the WS6 chain meets the Door and Hardware Federation's TS003:2012 requirements and holds the door slightly open so you can identify a caller before releasing it. It is a screening aid for answering the door rather than a lock, and only helps while the chain is engaged. From inside, it comes off by closing the door and sliding the chain free, so it does not stand in the way of leaving. Best for Checking who is at a wooden front door before you open it fully. Good

Our verdictOur verdictResearched Solon Security, which makes the Defender range, says this one-piece steel brace withstands up to 250kg of force and adjusts from 730 to 1130mm on hinged doors, or 635 to 1060mm in a sliding-door track. It needs no fixings, and Solon is clear it is extra security alongside your existing locks, not the main lock on an outside door. Because it blocks the door, keep it somewhere obvious and make sure everyone at home can lift it away quickly. Best for A removable extra layer at night on a door you control, alongside your normal locks. Good

Our verdictOur verdictResearched Yale's catalogue lists the P1037 as a surface-fitted chain for seeing who is calling before you open up properly. Yale gives no security standard for it, unlike the TS003 WS6, so treat it as a basic screening aid. From inside, it comes off by closing the door and sliding the chain free. Best for A basic chain for checking a caller, where no stated standard is needed. Good

Our verdictOur verdictResearched Lifeventure says this 10g device fits nearly all internal doors and is meant to add security while you sleep away from home. It carries no security rating, so treat it as a privacy aid rather than a lock. Do not use it on a fire door or where HMO or building rules forbid extra locks, and practise removing it so you can get out quickly in the dark. Best for Extra privacy on an internal door when travelling, where the venue's rules allow it. Good
Worth knowing
Who shouldn't buy it: Don't buy it if you need real forced-entry resistance, or the door is a fire door or in a building whose rules (such as an HMO's) rule out extra locks. | |||||

Before you buy
Start by naming the job, because these three types do different things.
A door chain or limiter holds the door slightly open so you can identify a caller and refuse entry without opening up; it is a screening aid, not a lock, and only helps while it is on. A door brace is a steel bar wedged between the floor and the handle, or laid in a sliding-door track, as a removable extra layer at night; Solon Security is clear its Defender brace is not the main lock for an outside door. A travel lock is a small privacy device for an internal door while you sleep away from home.
Then look for a stated standard, and treat its absence as a fact rather than a fault.
The Door and Hardware Federation's TS003 is the UK specification for door chains and limiters, and Yale says its WS6 chain meets TS003:2012. Yale states no standard for its surface-fitted P1037, Solon gives a force figure rather than a certificate for the Defender brace, and Lifeventure gives no rating for its travel lock. Phrases like heavy duty or anti-burglar on a listing mean nothing until the maker names a standard for that exact model, and we only show a rating where that is the case.
Check the door and the floor before you buy.
Yale lists the WS6 chain for wooden doors, so with a uPVC or composite door, ask its supplier or installer first. Solon says the Defender brace adjusts from 730 to 1130mm on a hinged door and from 635 to 1060mm in a sliding track, braces against the underside of the door knob or handle, and must not stand on a loose rug or floor mat. Lifeventure lists its lock for internal doors. Measure the door and the handle height, and check what the floor surface is.
Put the escape route first.
Fire and rescue services and the government's home fire safety advice both say to keep exits clear and to know how everyone will get out, and the same logic applies to anything that holds a door shut. A chain comes off by closing the door slightly and sliding it free; a brace needs enough slack to lift away quickly, which Solon's instructions say to allow; a travel lock should be practised until you can remove it in the dark. Keep door keys where everyone can find them, and never add a device to a fire door.
Finally, remember what each device is for.
A chain does its best work against the doorstep caller you are not sure about, so use it every time, alongside a viewer or video doorbell and the habit of asking for identification; our family safe word and AI scams guides cover the phone tricks that often come first. A brace is for the hours you are home and the door is already locked. A travel lock is for a hotel or hostel room, only where the venue allows it. For the door itself, money goes on the lock and the frame; our smart locks and door and window alarm pages cover those.
We verify every product's specifications against at least two independent sources, re-check its UK price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labelled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test — and commissions never change a ranking either way.

Common questions
Does a door chain actually stop someone getting in?
Not on its own. A chain holds the door slightly open so you can see and speak to a caller, and refuse entry, without opening up fully. It only works while it is engaged. Yale describes its chains as helping you identify a caller before the door is fully released, and says its WS6 chain meets the DHF TS003:2012 specification for door chains and limiters; many chains state no standard at all. Use it with the lock, not instead of it.
Are door braces and portable locks a fire risk?
They can be if they slow your exit. Home fire safety advice from the government and fire and rescue services is to keep escape routes clear and to be able to get out quickly, and a device that holds a door shut is part of that route. Solon says to allow enough slack in its Defender brace to remove it quickly. If anyone at home could not lift a bar or slide a chain in the dark, or the door is a fire door, do not use one.
Can I use a door brace or travel lock in a flat or HMO?
Usually you should not. Flats and houses in multiple occupation have fire doors and escape-route requirements set by the building's fire risk assessment and the landlord's licence conditions, and adding a device that blocks a door can breach them. The same applies in many hotels and hostels, so check the venue's rules before using a travel lock. If you feel unsafe in rented accommodation, raise it with the landlord or managing agent, who can fit proper locks that comply.
Will a door chain fit a uPVC or composite door?
Check with the door's supplier or installer first. Yale lists its WS6 security chain for wooden doors, and states no door type for its P1037 chain. uPVC and composite doors are built differently from solid timber ones, so fixing hardware into them is a question for the door maker, who can tell you which chain or limiter suits that door and whether fitting one affects its guarantee. Do not drill into a uPVC or composite door on a guess.
How strong is a freestanding door brace?
Solon Security says its Defender Door Brace withstands up to 250kg of force, adjusts without tools using a push button, and works on hinged doors between 730 and 1130mm or in a sliding-door track between 635 and 1060mm. That is the maker's figure rather than a certified rating, and Solon also says the brace is extra security alongside your existing locks, not the main lock on an exterior door, and must not be used on a loose rug or floor mat.
What is a travel door lock, and is it worth packing?
It is a small, pocket-sized device for keeping an internal door shut while you are in the room. Lifeventure says its version weighs 10g and can be fitted to nearly all internal doors. It carries no security rating, so treat it as a privacy aid rather than real forced-entry resistance. The door to a hotel or hostel room is often a fire door, so ask the venue before using one and do not if they say no. Practise taking it off before you sleep.
