Steel security door service contracts — insurer-graded lock service, hinge condition, frame integrity, panic hardware where fitted, maintained to keep the security spec your insurance policy requires.
Twelve standard service lines covered as part of every contract — on top of the door-type-specific scope listed elsewhere on the page. One contract, one engineer team, one document trail.
Steel security doors are an insurance-graded asset — downgrading the lock or hinge spec during repair can void cover. A service contract keeps the lock cylinders correctly lubricated, the hinges secure, and the frame in tolerance, so the door performs to its rated security level for its full life. The cost of the contract is trivial against the consequences of an insurance claim refused because a previous repair substituted the wrong-spec cylinder.
Insurer-graded locks rated to LPS 1175 (Loss Prevention Standard, attack-resistance) or TS 007 (3-star anti-snap cylinder) must not be downgraded during repair. Hinges to BS EN 1935. Where the door is also a fire door, all components must maintain fire certification per BS EN 1634-1. Where the door is also an emergency exit, BS EN 1125 / BS EN 179 panic hardware compliance applies.
Wherever your premises are, the same engineer team carries your documentation between visits. One contract, one accountable team, one document trail — whether you have a single site or a multi-region estate.
Yes — we use only matching-spec replacement cylinders and never downgrade. Where the original brand is uneconomical, we cross-reference to an equivalent insurer-rated equivalent and document the substitution to maintain the audit trail.
Annual is the baseline for most insurer-graded cylinders. Six-monthly is sensible for high-cycle operations (warehouses, distribution, late-night retail). Lubrication should always be PTFE or graphite-based — oil attracts dust and accelerates cylinder wear.
Identified at every visit, quoted for repair or treatment as a separate work order. Surface rust is treatable; structural rust on weld points usually means frame replacement — better to catch early before it spreads.
Yes — the steel security spec and fire certification are maintained together. All replacements are CE/UKCA marked for both security and fire as applicable. Documentation covers both compliance angles.
Re-survey to verify spec match against the new policy. Where the existing door is below the new specification, options are: spec-upgrade kit (where possible), full door replacement, or documented derogation from the insurer. We help with all three.
Yes — contracted sites get priority emergency response and standard repair rate (no urgency premium). Same-day cylinder change typical for most insurer-graded locks. Replacement cylinders match original spec.
A short email or a photo of your door inventory is all we need. No site visit required in most cases.
