How we work.
Our process is designed to keep every project efficient, transparent, and fully compliant, from first contact to final certification.
Schedule a Consultation
Every successful project starts with a conversation. Our specialists take the time to understand your building, your compliance responsibilities, and your operational challenges. We’ll assess your needs, outline clear next steps, and provide expert guidance .
Survey and Discovery
We begin with a detailed on-site survey or design review. Our engineers assess system condition, access, and compliance requirements — identifying risks, inefficiencies, and opportunities for improvement. This stage sets the technical and regulatory foundation for the project.
Design and Proposal
Based on our findings, we produce a tailored solution — complete with scope of works, costings, and timelines. Whether it’s new installation, remedials, or maintenance, every proposal is engineered for compliance, performance, and value.
Delivery and Implementation
Our qualified engineers carry out the work with precision and accountability. From installation and remedials to commissioning and testing, we deliver to specification — maintaining clear communication and site safety throughout.
Certification and Aftercare
Once the work is complete, we provide full documentation: reports, test certificates, and compliance evidence for your records. We also offer scheduled maintenance and re-testing plans to keep your systems compliant year after year.

Yes. Nitor Ventilation provides full UK coverage. Our engineers operate regionally, allowing us to support clients across commercial, industrial, healthcare, education, and residential sectors with consistent standards and fast response times.

How long does a typical fire damper testing project take?
Project duration depends on building size, access, and number of assets. As a guide, most fire damper testing and certification projects are completed within a few days, with remedial works scheduled immediately after testing to minimise downtime.
