For a typical uPVC front or back door, do not start by looking for BS 3621 on the euro cylinder. Most modern uPVC doors use a multipoint locking mechanism operated by a euro-profile cylinder, so the relevant checks are usually the policy's multipoint-lock requirement, the condition and operation of the complete locking strip, and the security rating of the replacement cylinder where applicable.
The insurer may ask what type of lock is fitted rather than name a cylinder standard. Current LV= guidance is a useful example: where its minimum-security condition applies, it accepts a three-point multipoint locking system for double-glazed doors as one route. Separately, current police crime-prevention guidance recommends a TS007 three-star euro cylinder when changing suitable door locks. Those two pieces of guidance answer different questions: one is an insurer's policy condition; the other is a security recommendation.
At Swift Locksmiths we therefore check both the insurance wording and the physical door system. A three-star cylinder is valuable, but it does not repair a failed gearbox, a door that has dropped or hooks that no longer line up with their keeps.

uPVC Door Insurance Standards: The Short Answer
For home insurance, check your own policy first. On uPVC and many composite doors, insurers commonly describe the requirement as a multipoint locking system rather than insisting on BS 3621. If the euro cylinder is being replaced, current police guidance recommends a TS007 three-star cylinder. If the doorset carries PAS 24 certification, that is useful evidence about the tested doorset configuration, but it does not replace the need to satisfy your individual policy wording or keep the lock working correctly.
What Lock Is Usually Fitted to a uPVC Door?
A typical uPVC entrance door has a long multipoint locking strip recessed into the door edge. Lifting the handle moves hooks, rollers, mushrooms, shootbolts or other locking points into keeps in the frame. Turning the key then secures the gearbox so the handle cannot simply retract those points from outside. The euro cylinder is the small removable component that accepts the key and operates the gearbox.
That distinction is essential. Customers often call the whole assembly "the euro lock", but the euro cylinder is only one component. Insurance questions about a "three-point lock" generally refer to the multipoint arrangement, whereas TS007 is a cylinder and associated-hardware security specification.
| Marking or description | Applies to | What it means for insurance |
|---|---|---|
| Three-point or multipoint locking | Complete locking mechanism/door arrangement | Can be an insurer-approved route where the policy explicitly accepts multipoint locking. |
| TS007 three-star | Replacement euro cylinder | Strong current security benchmark recommended by police when changing suitable cylinders; not automatically an insurer requirement. |
| TS007 one-star + two-star hardware | Cylinder plus protective handle/escutcheon | Can create a three-star security solution, subject to compatibility and condition. |
| PAS 24:2022+A1:2024 | Complete new doorset/window as tested | Shows enhanced security performance of the manufactured doorset configuration, not a blanket home-insurance approval. |
| BS 3621 | Single-point thief-resistant lock assembly | Commonly relevant to timber doors; do not expect it to be stamped on a normal euro cylinder. |
| No visible standard | Unknown | Does not prove the door is insecure, but it means further identification may be needed before making an insurance declaration. |
What Does TS007 Add to a uPVC Door?
TS007 addresses enhanced security performance for replacement cylinders and associated hardware. BSI's current certification records use TS007-1:2024 and show one-star and three-star cylinder grades, plus two-star security hardware. The Metropolitan Police says that when changing a euro-cylinder lock, choose a three-star cylinder meeting TS007 because it improves resistance to common attacks including snapping, drilling and bumping.
That makes TS007 particularly relevant when you are replacing a cylinder after lost keys, burglary damage, wear or a security review. It is still important to fit the correct cylinder length so the product does not project unnecessarily beyond the protective furniture.
Does PAS 24 Mean the Door Automatically Meets Insurance Requirements?
No. PAS 24 is a performance specification for a complete manufactured doorset or window. The current amended edition is PAS 24:2022+A1:2024. A PAS 24 door can be excellent evidence that a particular doorset configuration was security tested, but your insurer can still ask a separate question about the current lock arrangement or require certain security devices to be used when the property is unattended.
Doors also change after installation. Cylinders are replaced, handles are upgraded, multipoint strips wear and hinges move. We therefore treat the current condition of the door as important even when an original PAS 24 label is present.
How Many Locking Points Does a uPVC Door Need for Insurance?
There is no single answer that applies to every insurer. Current LV= guidance gives a three-point multipoint system as an accepted route for relevant double-glazed doors where its additional minimum-security requirement applies. Another insurer may define the requirement differently, and a policy endorsement can name a specific arrangement. Count the actual effective locking points rather than assuming every roller or latch is treated the same way by an insurer.
From a locksmith perspective, the quality of engagement matters as well. Three hooks that are not entering the keeps because the door has dropped are not functioning as intended. If the key only turns when you pull the door hard toward you, the first job is diagnosis and alignment.
What Should You Photograph for an Insurance Check?
- The full inside and outside of the door.
- The door edge with the door open, showing the multipoint strip and manufacturer markings.
- The cylinder face, including any TS007 stars or other marks.
- The handles or escutcheons, especially if they carry a security mark.
- The keeps in the frame and the locking points on the strip.
- Any PAS 24 or doorset label you can identify without dismantling the door.
These photographs give an insurer or locksmith far better information than the phrase "normal uPVC lock".
When Should a uPVC Lock Be Upgraded?
We would consider an upgrade where the cylinder has no recognised security evidence, projects excessively, has been damaged, or the keys are no longer controlled. We also look at weak handles, worn gearboxes and poor frame engagement. If the multipoint strip is obsolete, repair may involve matching a replacement gearbox or full mechanism rather than simply installing a new cylinder.
A New Cylinder Does Not Cure a Failing Multipoint Lock
If the handle is stiff, hooks do not line up or the door only locks under pressure, the fault may be alignment or the gearbox. Fitting a premium cylinder into a failing mechanism can leave the original problem untouched and can make the key feel even harder to operate.
How We Recommend Checking Your Insurance Position
When a customer asks us whether a lock is "insurance approved", our first step is not to give a blanket yes or no. Home insurance is a contract between the policyholder and the insurer, and the security wording can differ between products. The Association of British Insurers tells homeowners to read their own policy because cover varies and says an insurer will tell the customer which security devices it approves. That is the right starting point for upvc door lock standards for home insurance as well.
We therefore separate three questions. First, what lock or security hardware is physically fitted? Second, what recognised standard, if any, does that exact product meet? Third, what does the policy schedule, endorsement or statement of fact actually require? Those questions overlap, but they are not interchangeable. A good lock can be fitted to a door even where the policy does not impose a minimum-security condition, and a lock can be mechanically sound while still not matching a specific declared requirement.
| Evidence | What it tells you | How much weight to give it |
|---|---|---|
| Your current policy schedule and endorsements | Any minimum-security condition specifically applied to your home. | Highest priority for insurance compliance. |
| Statement of fact / proposal answers | What you told the insurer about your doors, locks, alarms and occupancy. | Important because inaccurate assumptions can create disputes. |
| Current policy booklet | Definitions, exclusions and the way security conditions operate. | Read alongside the schedule, not instead of it. |
| Markings on the actual lock | Whether the installed product carries a recognised standard or certification. | Useful physical evidence, provided the marking is genuine and applies to the complete product. |
| Manufacturer or certification directory | Confirms the exact model and certification status. | Strong technical evidence. |
| Retail descriptions or old invoices | Can help identify a product but may be incomplete or outdated. | Supporting evidence only. |
| General internet advice | Useful background, but it cannot override your individual policy. | Lowest priority for insurance decisions. |
Why Door Type Changes the Answer
uPVC and composite doors usually use multipoint systems and euro cylinders rather than a conventional single mortice lock. Your policy may therefore refer to multipoint locking, a minimum number of locking points or other door-specific wording. The euro cylinder can have its own TS007 rating, while a complete doorset may also have PAS 24 evidence.
This is one reason the phrase "British Standard lock" can be misleading when used without context. BS 3621 is a highly relevant standard for thief-resistant single-point lock assemblies operated by key from both sides, commonly encountered on timber doors. It is not a universal label that describes every secure external door. Modern uPVC and composite doors frequently use a multipoint strip with a euro cylinder, and those parts are assessed through different standards and certification routes.
Current Metropolitan Police guidance reflects that distinction. It tells householders changing a euro-profile lock to choose a three-star cylinder meeting TS007 and reminds users of multipoint doors to "lift, lock and remove" the key. That is operational security advice rather than an insurance contract term, but it shows why the hardware on a modern door needs to be understood as a system.
How Current Insurance Guidance Demonstrates Policy Variation
A useful current example is LV='s home-insurance guidance. LV= says some properties need additional security and that the customer is told during the quote and in the policy documents if that applies. Where its minimum-security condition is required, the current guidance lists several acceptable door-lock routes rather than one universal lock: mortice deadlocks with at least five levers, locks to a minimum of BS 3621, a three-point multipoint locking system for double-glazed doors, or existing locks supplemented by key-operated locks at the top and bottom.
That example matters because it proves two things. First, an insurer can impose a defined minimum-security condition. Second, the acceptable solution can depend on door construction. It would therefore be inaccurate for us to tell every homeowner that one badge must appear on every door. Other insurers can use different wording, and an endorsement on your schedule can be more specific than the insurer's general website.

A Five-Step Check We Use Before Recommending an Upgrade
1. Identify every external door separately
We record whether each entrance is timber, uPVC, composite, aluminium, sliding, double-leaf or another construction. The main front door, rear door, side door and doors from an integral garage can have different hardware and different policy treatment.
2. Identify the complete locking arrangement
We look beyond the visible keyhole. On a timber door that may mean a mortice sashlock, deadlock or night latch. On a modern door it may mean a euro cylinder operating a multipoint gearbox with hooks, rollers and bolts. We also check supplementary bolts and the security of the frame and keeps.
3. Read genuine markings rather than guessing
A five-lever lock is not automatically BS 3621. A euro cylinder described as anti-snap is not automatically TS007 three-star. We look for a recognised mark, the manufacturer and, where practical, the product record.
4. Compare the hardware with the exact insurance wording
We use the policy schedule, statement of fact and any minimum-security endorsement. If the wording is ambiguous, the safest route is for the policyholder to ask the insurer to confirm the acceptable arrangement in writing.
5. Repair operating faults before treating the job as a standards upgrade
A certified lock that cannot fully engage because the door has dropped is not giving the performance the owner expects. We correct alignment, worn keeps, loose handles or gearbox faults so the security hardware can actually work as designed.
Questions Worth Asking Your Insurer
- Does my policy have a minimum-security endorsement, or are the lock details simply rating information?
- Which external doors does the requirement apply to?
- Does the policy accept a multipoint locking system on uPVC or composite doors?
- If a British Standard is named, which standard and version or certification mark should I look for?
- Do supplementary door bolts count, and must they be key-operated?
- Must the security devices be put into operation every time the home is left unattended?
- If I change a door or lock during the policy term, do I need to tell you?
- Can you confirm the answer by email or in my online policy documents?
Those questions are deliberately practical. They reduce the chance of relying on a memory of what was said during a quote several years ago or on advice written for a different insurer.
Why Correct Operation Matters as Much as the Badge
Security conditions often concern the lock being used, not merely present. A multipoint door can look shut while only the latch is engaged. Police guidance therefore stresses lifting the handle, locking and removing the key. On a timber door, a deadlock may need to be actively thrown with the key rather than relying on a spring latch. If a policy says security devices must be put into full and effective operation while the property is unattended, the everyday locking routine matters.
This is also where mechanical faults become relevant. If a customer has to push a door with a shoulder, pull the handle sideways or turn the key against heavy resistance, the mechanism may not be reaching its full locked position. We advise fixing that fault rather than assuming the standard stamped on the faceplate makes the problem harmless.
What Recent Insurance Disputes Teach Homeowners
Published Financial Ombudsman decisions show why clear records matter. Recent home-insurance disputes have involved security conditions requiring windows or alarms to be used while the property was unattended. The Ombudsman considered the actual policy wording, the evidence about whether the condition was met and whether the breach was material to the loss. Those decisions are fact-specific and are not a promise about how any future complaint will be decided, but they reinforce the value of understanding and documenting the security requirements before a burglary occurs.
For the homeowner, the practical lesson is not to panic if you discover a mismatch. Instead, establish what the policy actually says, photograph the existing hardware, contact the insurer if necessary and arrange a proportionate upgrade. If a claim is already in progress, preserve evidence and avoid making unnecessary alterations until the insurer or police have advised what can safely be repaired.
Common Insurance-and-Lock Mistakes We See
| Mistake | Why it causes problems | Better approach |
|---|---|---|
| Assuming every five-lever lock is BS 3621 | Lever count alone does not prove certification. | Look for the correct standard marking or verify the exact model. |
| Expecting BS 3621 on a typical euro-cylinder multipoint door | BS 3621 is not the normal way a replacement euro cylinder is described. | Identify the multipoint system and cylinder rating; use the policy wording for insurance. |
| Buying a cylinder because the packaging says anti-snap | Marketing terms are not the same as independent certification. | Prefer verifiable TS007 three-star or another recognised high-security route where appropriate. |
| Ignoring a door that only locks when pushed or pulled | The lock may not be fully engaging and components may be under abnormal load. | Repair alignment or mechanism faults promptly. |
| Relying on a neighbour's insurer requirements | Different insurers and policies can impose different conditions. | Check your own schedule and endorsements. |
| Changing hardware after a burglary before recording it | That can remove evidence about the point of entry or prior condition. | Photograph damage and follow police/insurer instructions before non-urgent replacement. |
When We Recommend Upgrading Even If Insurance Does Not Demand It
Insurance compliance is a minimum contractual question; home security is a broader risk-management question. We may recommend an upgrade where a cylinder projects excessively, the handles are weak, a lock is badly worn, keys are uncontrolled, a door no longer aligns, or an older mechanism has no meaningful independent security evidence. The recommendation should still be proportionate to the door and the customer's circumstances.
For suitable euro-cylinder doors, current police guidance makes a TS007 three-star cylinder a straightforward benchmark when replacing the cylinder. On a timber entrance door, a current certified BS 3621 lock can be a strong option when key egress is appropriate. Where keyless escape is required, BS 8621 describes a different type of thief-resistant lock assembly that can be opened from inside without a key. Fire-safety and means-of-escape needs should never be ignored simply to chase an insurance badge.
How Swift Locksmiths Approaches This Work
At Swift Locksmiths, we start with the installed door, not a generic shopping list. We identify the lock, test the door open and closed, inspect keeps and handles, and explain which part of the system is security hardware and which part is simply the operating mechanism.
Our lock repair and replacement services cover timber, uPVC and composite door problems, including multipoint mechanisms, cylinders, handles and alignment faults. Where an insurance requirement is involved, we can explain the lock markings and practical options, but the insurer remains the authority on its own policy wording.
You can also read more about our independent local approach on our Swift Locksmiths company page. We have worked locally since 2006, and our aim is to give customers a clear diagnosis rather than sell the most expensive hardware automatically.
If you have a policy document in front of you and are unsure whether the installed lock matches what it describes, contact Swift Locksmiths and tell us the door type, visible markings and symptoms. A photograph can often help identify what you have before a visit, although physical inspection may still be required.
