Our security rated window bars are manufactured to order, with a typical lead time of 4–6 weeks from order confirmation and final specification. This reflects the additional manufacturing processes and strict quality controls required to meet LPS1175 certification standards.

Where hot-dip galvanising is specified for external installations, an additional 1–2 weeks should be allowed. This extended process ensures maximum corrosion resistance and long-term durability, particularly in exposed environments.

Lead times may vary depending on security rating (SR2, SR3, SR4), project size, and installation requirements, as certified products must be produced and installed in line with approved specifications. We will always confirm accurate timescales at quotation stage to align with your project programme.

The cost of security rated window bars reflects their certified performance, heavy-duty construction, and compliance with LPS1175 standards. As a high-security product, they sit at the upper end of the window protection range, particularly at higher security levels (SR3 & SR4).

Factors Affecting Price

Several key factors influence the final cost:

• Security Rating: SR2, SR3, or SR4 (higher ratings significantly increase cost)
• Bar Specification: 20mm vs 25mm solid steel bars
• Opening Size: Larger windows require more material and fabrication
• Frame Construction: 3mm vs 5mm thick angle frames
• Mesh Infill: Optional mesh panels add cost and complexity
• Finish: Standard powder coating vs galvanised and powder-coated
• Installation Requirements: Must comply with LPCB-approved fixing methods

Installation Considerations

Security rated systems often require:

• Installation in line with strict LPCB certification standards
• Fixing into approved substrates (typically masonry)
• Careful installation to maintain certification validity
• Additional time for commissioning and compliance checks

This can increase installation costs compared to standard window bars.

Additional Costs to Consider

• Hot-dip galvanising for external installations
• Bespoke colour finishes
• Access equipment (e.g. scaffolding or lifts)
• Structural preparation or builder’s works

Budget Guidance

Typical project budgets are:

Standard commercial applications (SR2–SR3):

• £600 – £1,500 per window installed

High-security applications (SR4):

• £1,200 – £3,000+ per window installed
