LPS 1175 SR3-rated sliding security door

By any measure, the past year has been uncomfortable reading for public sector housing providers. From Trafford to Norwich to Sheffield, residents’ testimonies and council decisions point to a recurring and deeply consequential issue: security doors that fail in service, degrade rapidly, or become so costly to repair that they are removed altogether—undermining safety rather than protecting it.

At Gallant House in Altrincham, a newly completed development intended to provide a fresh start for residents displaced from ageing 1960s flats, complaints of non-functioning security doors emerged barely two years after completion. Residents spoke openly about vandalism, antisocial behaviour and fear—conditions modern housing schemes are explicitly designed to prevent.

Elsewhere, Norwich City Council has been forced into reactive upgrades, retrofitting steel security doors to blocks that were originally built without effective locking systems. In Sheffield, the situation has gone further still, with security doors removed from communal corridors altogether after repeated vandalism made repairs financially unsustainable—leaving residents feeling, in their own words, “petrified”.

Taken individually, these are local failures. Taken together, they expose a systemic procurement problem. Security doors in public sector environments are often procured under intense financial pressure. Capital cost is immediate, visible and easily compared. Whole-life performance—resistance to abuse, durability under constant use, ease of repair and long-term reliability—is harder to quantify and therefore too often pushed down the priority list.

Yet the consequences of that imbalance are now playing out in real communities. “When a security door fails, it’s actually a safety failure than simply a maintenance problem” says Brett Barratt, Managing Director of Warrior Doors. “Public sector buyers are being asked to solve decades-long safety challenges with products specified on the shortest possible cost horizon. That simply doesn’t work.”

In each of the recent cases, failure followed a familiar pattern: doors not designed for sustained misuse, vandalism or heavy daily traffic deteriorated rapidly. Repair costs mounted. Performance declined. In some instances, removal was deemed cheaper than replacement—despite the obvious social and safety cost to residents.

A core issue, industry specialists argue, is that security doors are still too often treated as architectural components rather than safety-critical systems.

In high-density residential environments, a door performs multiple roles simultaneously. It controls access, deters crime, protects vulnerable occupants, supports fire strategies and directly shapes how safe people feel in their own homes. Failure in any one of those functions reverberates throughout the entire building.

“Doors in public housing have to be designed for reality,” Barratt says. “That means repeated impact, deliberate abuse, environmental wear and inconsistent maintenance access. If those conditions aren’t engineered in from the outset, failure is only a matter of time.”

One of the clearest lessons from these case studies is the importance of independently verified performance. Doors tested as complete systems—rather than as individual locks, leafs or frames—give procurement teams confidence that what is installed will perform as expected under real-world conditions.

This is where frameworks such as Secured by Design (SBD) and independently audited standards like LPS 1175 have growing relevance. SBD’s Police Preferred Specification requires products to be tested by UKAS-accredited bodies and subject to ongoing audit—ensuring that the door installed on site is identical to the one originally tested.

That philosophy closely mirrors Warrior Doors’ manufacturing approach. The company designs and manufactures its stainless steel security doors entirely in-house in Birmingham, including fully glazed SR2 and SR3 doorsets and the UK’s only LPS 1175 SR3-rated sliding security door. Steelwork, glazing, assembly and quality control remain under one roof, providing full traceability and accountability.

“In high-risk environments, a door is a system that has to perform under real attack conditions,” Barratt explains. “Independent certification removes ambiguity. It tells clients, insurers and end users exactly what that door can withstand, with tested results.

Ironically, decisions made to save money upfront frequently prove far more expensive over time. Emergency repairs, repeat call-outs, temporary security measures, additional CCTV, reputational damage and full door replacement all contribute to the true lifetime cost.

“These aren’t edge cases,” Barratt notes. “They’re predictable outcomes of under-specification. A door that can’t be economically repaired or hasn’t been independently tested for sustained attack becomes a liability, not an asset.”

As councils and housing associations face increasing scrutiny over building quality and resident welfare, the message from recent events is difficult to ignore: the cheapest door is rarely the most affordable one.

“Procurement teams are under pressure, and that’s understood,” Barratt concludes. “But security doors should be specified for the life they’re expected to lead. When you design and procure for longevity, resilience and verified performance, you protect residents—and you protect public money.”
