Security Grilles and Shutters UK Guide¶

Protect doors and windows with grilles, shutters, and security screens - from decorative to heavy-duty.

Choosing Security Grilles for UK Homes¶

Security grilles are a visible deterrent that can reduce burglary risk by over 60 %, according to Secured by Design. Wrought-iron window grilles start at £120 - £250 per window fitted. For a less permanent option, GrilleShield polycarbonate panels (£45 - £80 per panel) are shatterproof, UV-stable, and let light through. Collapsible concertina grilles (£200 - £400 per door) are popular for rear doors and side passages. All must comply with Part B building regulations regarding fire escape - grilles must have a quick-release mechanism on the inside.

Roller Shutters - Manual vs. Powered¶

Domestic roller shutters are becoming popular in UK homes. Manual aluminium shutters start at £350 - £600 per window fitted. Electric shutters with remote control cost £600 - £1,200. Brands like Somfy and Securisteel offer British-made options. Shutters provide insulation (R-value up to 0.5), noise reduction (up to 20 dB), and security. The Secured by Design certification guarantees police-approved security. Some insurers, including NFU Mutual, offer up to 15 % discounts for properties with shutters on all ground-floor openings. Ensure shutters have manual override in case of power failure.
