ATTMA Airtightness Tester Insurance | Air Leakage & Building Performance Assessor Cover | SRS Insurance
SRS Insurance provides specialist insurance for ATTMA-accredited airtightness testers and building performance assessors. Tailored PI and PL cover for air leakage testing, pressure testing, thermography, compliance reporting and building performance diagnostics.
Why Airtightness Testers Need Specialist Insurance
ATTMA testing is a compliance-critical activity.
Incorrect readings or reporting errors can lead to:
- Failed Building Control sign-off
- Project delays
- Additional construction costs
- Litigation from contractors, developers or clients
- Professional liability for invalid certificates
- Reputational damage
Despite this, many assessors hold insurance that does not cover:
Common insurance gaps we see
- No Professional Indemnity for reporting or certification
- Exclusions for measurement error or incorrect data
- No cover for Part L compliance work
- No protection for retrofit diagnostic testing
- No cover for thermographic surveys
- No public liability for high-risk commercial/industrial tests
- Inadequate PL limits for large developers
- Exclusions for “specialist testing work”
ATTMA testers require insurance that understands their precision-driven professional risk.

Core Insurance Covers for Airtightness Testers
Airtightness testing is a professional activity — meaning Professional Indemnity is essential.
1. Professional Indemnity Insurance (PI)
Covers claims relating to:
- Incorrect pressure testing results
- Invalid compliance reports
- Measurement error
- Incorrect calculations
- Failure to follow ATTMA methodology
- Losses caused by inaccurate certification
- Incorrect diagnostic surveys
- Builder/developer financial loss due to incorrect readings
This is the most important cover for ATTMA testers.
2. Public Liability Insurance (PL)
Covers accidental damage or injury during testing:
- Damage to doors, frames or finishes
- Damage caused by fans or equipment
- Injury to building occupants
- Damage during access or surveying
Often required by main contractors and developers.
3. Employers’ Liability Insurance
Required if you have staff or labour-only subcontractors assisting with testing.
4. Tools & Equipment Insurance
Covers:
- Blower door systems
- Fans & rigs
- Diagnostic tools
- Data loggers
- Thermal imaging cameras
- Carry kit & calibration equipment
Given the high value of airtightness testing gear, this is strongly recommended.
5. Contract Works Insurance (Optional)
Covers damage to work in progress if you’re involved in remedial or pre-test sealing work.

We provide cover for:
