If you’re comparing uPVC doors, “PAS 24” is one of the most useful specs to understand. In simple terms, it’s a UK security test standard for enhanced-security doorsets. And because most break-ins happen through doors and ground-floor openings, it’s a practical checkbox—especially for front doors, back doors, and side entrances.
In this short guide, you’ll learn what PAS 24 means, what it does (and doesn’t) guarantee, and how to use it to compare quotes properly.
What is PAS 24?
PAS 24 is a performance standard that tests how well a door resists common attack methods. It looks at the door set as a system—not just a lock or handle. That includes:
-
The door slab/panel
-
The frame and reinforcements
-
Hinges and hardware
-
Locks and keeps
-
Glazing (if the door has glass)
-
Installation-critical elements like fixing points
Because of that, PAS 24 is more meaningful than a single “high security lock” claim. In other words, it helps confirm the whole door setup works together under stress.
Why PAS 24 matters for uPVC doors
uPVC doors can be extremely secure when they’re built and installed correctly. However, security isn’t only about choosing a door that “looks solid.” Instead, you want proof the setup has been tested.
PAS 24 matters because it:
-
reduces weak links (like flimsy keeps or poor hinge-side strength)
-
supports insurance and buyer confidence when you sell
-
pushes spec clarity so quotes are comparable (apples to apples)
PAS 24 vs Secured by Design (SBD): what’s the difference?
You’ll often see PAS 24 mentioned alongside Secured by Design (SBD).
-
PAS 24 = a test standard for performance.
-
SBD = a police-backed security initiative that usually requires tested products (often including PAS 24) plus additional requirements depending on product type.
So, PAS 24 is a solid benchmark. Meanwhile, SBD can be an extra layer of reassurance when available.
What to ask an installer (so you don’t get “PAS 24-ish”)
When you request quotes, ask these specific questions:
-
Is the doorset PAS 24 certified? (Not just the lock.)
-
Which locking system and cylinder are included? (Example: anti-snap cylinder, 3-star TS 007.)
-
If there’s glazing, is it laminated where needed? (Especially on larger glass areas.)
-
What’s included in the installation? (New trims, making good, internal cill, disposal, etc.)
-
Can you show the certification evidence or product spec sheet?
If an answer feels vague, push for clarity. A reputable firm will explain it quickly.
Common mistakes that reduce security (even with a good door)
Even a strong door can underperform if the final details are wrong. For example:
-
Poor frame fixings into weak masonry
-
Gaps and misalignment that stop locks engaging cleanly
-
Cheap cylinders paired with good multipoint locks
-
Too much glass without laminated protection
That’s why installation quality matters just as much as the product.
A quick “good spec” checklist for a uPVC front door
If you want a simple starting point, aim for:
-
PAS 24 certified doorset
-
Multipoint locking
-
Quality anti-snap cylinder (ideally TS 007 3-star)
-
Reinforced frame (as specified by the system)
-
Laminated glazing if the glazed area is large or low-level
-
Professional fitting with proper adjustment and sealing
