All Secure Doors Ltd. was appointed to deliver the replacement of an existing steel entrance at the historic Bishop’s College, a listed building where preserving the architectural integrity of the property was of paramount importance.

Working on heritage buildings requires a sensitive approach, combining traditional craftsmanship with modern engineering. Our team delivered a bespoke arched W20 steel door system, carefully designed to complement the building’s original character while providing improved durability, security and long-term performance.

From the initial site survey through to the final handover, every stage of the project was carried out with meticulous attention to detail and respect for the historic fabric of the building.

When it comes to protecting critical utility infrastructure, there should be no compromise.

Substations, water treatment facilities, energy sites and critical assets require more than just a “steel door”, they require properly tested and certified security solutions designed to resist real attacks and protect operational continuity.

Choosing the correct supplier matters.
Choosing proven performance matters.
Choosing compliant products matters.

At All Secure Doors Ltd, we specialise in high-security steel door solutions for critical infrastructure and utility environments, including:

✔ LPS 1175 Certified Security Doors
✔ SR2 / SR3 / SR4 Rated Solutions
✔ Flood Resistant Doors
✔ Fire Rated Steel Doors
✔ Utility & Substation Protection
✔ Nationwide Supply & Installation

In critical infrastructure, security is not an upgrade, it is a necessity.

Don’t compromise on protection.
Choose tested performance.
Choose the correct supplier.

Not all “secure doors” are actually secure. Especially in critical infrastructure.

Across utility sites and substations, we still see doors that look robust, but offer little real resistance when tested.

That’s where LPS 1175 SR2 makes the difference.

SR2-rated doors are designed to withstand opportunistic attack attempts using common tools, exactly the level of threat most substations and utility assets face daily.

For asset managers, this isn’t just about compliance.
It’s about risk control, asset protection, and operational continuity.

At All Secure Doors Ltd, we support utility providers with:

✔ LPS 1175 SR2 & SR3 security-rated steel doors
✔ Substation security upgrades & replacements
✔ Flood-resistant door solutions
✔ Nationwide installation & surveys
✔ Fully compliant, tested, and certified systems

Because in environments like substations,
a weak door isn’t just a defect. It’s a vulnerability.

If you’re reviewing site security or planning upgrades, now is the time to act.
