Secure sliding doors (PAS 24) across the West Midlands
Most homeowners choosing secure sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Replacing an old slider in the West Midlands that has its glass beads on the outside? That is a weakness a modern internally glazed door removes.
If your West Midlands home has a rear garden reached by a side gate or shared alley, the back door is the one to specify with PAS 24 testing and laminated glass.
- Robust interlocks where the panels meet reduce the chance of the door being levered open at the overlap, which is where a sliding door is often probed first.
- Specifying a tested door when you replace an old slider gives you a clear security standard to compare against, even though Approved Document Q only applies to new homes.
- Anti-lift devices in the head of the frame stop a closed sliding panel being levered up and lifted off its track, which is a classic weakness of older sliders.

Daylight and glass in the West Midlands
Sun angles matter for big glazed doors. Around the West Midlands, midday sun reaches about 61° in summer and drops to about 14° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Approvals in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Questions about secure sliding doors in the West Midlands
Do I need building approval for secure sliding doors in the West Midlands?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
Does Approved Document Q apply to my replacement door?
No, Approved Document Q sets security requirements for doors and windows in new dwellings in England and does not apply when you replace a door in an existing home. Choosing a door tested to PAS 24 is still a sensible benchmark for a replacement, because it gives you a recognised standard rather than relying on how the hardware looks.
How do anti-lift devices work on a sliding door?
Anti-lift devices are blocks or bolts fitted in the head of the frame or on the sliding panel that fill the gap above the panel when the door is closed. Without them, some older sliding panels could be lifted up and out of the bottom track. With them, the panel cannot be raised far enough to clear the track.
What is Secured by Design?
Secured by Design is a police-backed initiative that sets security standards for homes and products, and its requirements for doors build on PAS 24. Products and developments can gain recognition under the scheme. We are not a Secured by Design member company; if a project specifies it, tell us at the start so we can check what the specification requires.
