Asbestos air monitoring by UKAS-accredited specialists
UKAS-accredited air monitoring ensuring full compliance
Spectra Analysis Services Ltd is fully accredited by UKAS to ISO/IEC 17025, accreditation number 2621, for air sampling and fibre counting.
Our skilled analysts provide swift, accurate on-site testing for airborne asbestos fibres, ensuring compliance with the Control of Asbestos Regulations 2012 and HSG 248.
We operate a fleet of mobile laboratories across the UK, each equipped with high-flow monitoring pumps, phase contrast microscopes, power inverters, and all essential tools to deliver immediate, dependable results.

Our Expertise
Testing sits in a separate accredited company from our removal teams. That independence is deliberate, and it is what makes a clearance certificate worth having.
Analysts, not box tickers
Our analysts hold current P403 and P404 certification and work to documented, audited procedures. Sampling strategy, flow rates, and counting are all traceable, so results stand up to scrutiny.
Where and when you need us
Mobile laboratories mean we mobilise quickly for planned clearances and for the unplanned discovery that stops a site. Reports are issued the same day in most cases.
Our Air Testing and Monitoring Services
A wide range of asbestos air testing services to ensure safe removal, reoccupation, and continuous monitoring.

Certificate of reoccupation
Issued after all four clearance stages have been completed successfully, with the evidence to support it.
Decontamination unit clearance testing
Ensures the safety and compliance of decontamination units after use.
Background sampling
Establishes baseline airborne fibre levels prior to asbestos work starting.
Leak and enclosure check sampling
Identifies breaches in enclosures during asbestos removal operations, before they become incidents.
Reassurance sampling
Confirms that fibre concentrations stay within safe limits following remedial works.
Personal monitoring
Assesses operative exposure during asbestos-related tasks, supporting RPE and control decisions.
Compliance sampling
Evaluates the effectiveness of respiratory protective equipment and control measures in practice.
Why UKAS Accreditation Is Important
Under CAR 2012, all air monitoring for airborne asbestos fibres must be carried out by a laboratory accredited to ISO/IEC 17025.
Technical competence, proven
Accreditation demonstrates technical competence, traceability, and impartiality, ensuring every test we perform adheres to the highest recognised standards of accuracy and reliability.
Impartiality that matters
Because our testing company is separate from our removal teams, nobody at Spectra is marking their own homework. Duty holders get an independent result they can rely on and evidence a regulator will accept.

Our case studies illustrate proven capability in delivering technically demanding projects on time and within budget.
Nationwide Coverage, Fast Results
Our dedicated mobile laboratory network enables rapid mobilisation and on-site results across the UK. Whether for routine reassurance testing, emergency clearance certification, or long-term monitoring, our team delivers accurate, professional reports exactly when and where you need them.
