Frequently Asked Questions
Answers to Common Questions
LPS 1175 is a security testing standard used to rate how long a door or screen resists forced entry using different tools. Ratings range from SR1 (lower risk) to SR8 (extreme risk), and we help you select the right rating for your site and insurer requirements.
We offer both. Most clients use our full survey, manufacture and installation service, but we can also supply doors and frames for installation by your own contractor where required.
Lead times depend on the product, rating and quantity. Standard doors are typically manufactured within a few weeks; bespoke or higher security rated products can take longer. We confirm a firm lead time at quotation stage.
Yes. We regularly install on live substations, water treatment works and occupied commercial buildings, working around site access, permits and safety requirements to minimise disruption.
We install nationwide across the UK, with experienced teams working on utility, industrial, commercial and public sector projects.
