Air Tightness Testing

The air tightness of new houses and flats has a significant effect on energy efficiency and comfort for occupants. Building Regulations set a maximum level of air permeability that must not be exceeded. Technical Standard L lists ways of proving compliance with this requirement, which includes Air Tightness Testing.

AFM has ATTMA registered Air Tightness Testers who use calibrated equipment and work  to recognised procedures, they can also help with advice on how to comply with the standard. 

 With all our testing, our aim is to help clients achievethe required standards with an efficient, cost effective  and easy to useservice.



AFM can advise on potential leakage issues before testing and having trained staff based in Guernsey, we can respond quickly to requests for testing. Pre-completion Air Tightness testing in new dwellings is undertaken to confirm that air leakage into or out of new dwellings does not create excess energy use.

Compliance Testing

AFM offers comprehensive compliance services. We employ qualified technicians and tradesmen who deliver to high standards. Our team is able to design an ongoing preventative maintenance programme as well as solve any immediate issues which may arise. We have extensive experience in dealing with all aspects of the job.

Portable Appliance Testing

To protect your staff and office infrastructure, from faulty electrical items, a series of visual and electrical tests are carried out by our teams.

Fixed Wired Testing

All electrical circuits require full load testing and inspections every 3 - 5 years, in accordance with H&S regulations.

Air Quality Testing

AFM can provide bacteria tests and survey options to check the quality of the fresh air within your building.

Potable Water Testing

If your building has any form of hot or cold water storage systems, then you are required to test and sample the water. AFM acredited teams can manage required testing and sampling of water in hot and cold storage water storage systems.

Thermal Inspections

Our state of the art thermal camera will identify any potential fire risks in your building by locating hot spots on fuse boards and cabling.

Emergency Lighting

Emergency lighting in offices must be tested at regular intervals, to ensure correct operation and lighting levels are in place in case of emergency.

 Fire Alarm Testing

AFM will carry out weekly and monthly bell testing and device checks, to ensure that the systems are fully operational.

Health and Safety Audits

AFM and our partners will survey your building and report any health and safety issues in relation to risks to 3rd party contractors.

F Gas Regulations

Air conditioning systems now require specific monitoring checks for leakages and chemical record keeping, to comply with regulations.

Air Tightness

Pressure and room integrity checks are required in computer rooms fitted with suppresent fire fighting chemicals.

Computer Room Audit Services

Condition Surveys

AFM can provide the expertise to undertake Condition Surveys to allow you peace of mind. Our qualified Technicians are on hand to answer any query you may have regarding the condition of your premises and to offer constructive advice and provide comprehensive reports on our findings.

Enclosure Integrity Testing

We can test specialist enclosures to ensure that they achieve required levels of air tightness.

​Such enclosures include computer rooms fitted with gas drench systems, where enclosure integrity is vital for effective performance of fire suppression. 

​ All technical services testing is performed in accordance with Industry Standards, which include regular equipment calibration.

Building Inspections and Condition Surveys

Our building inspection and condition surveys will highlight any issues with regards to soundness of installation, fire door inspections and will ensure that you have the correct fire stopping controls in place. 

 Our fully trained personnel are able to identify any issues or inefficiencies and outline any remedial actions that may be required.

Environmental Surveys

We undertake various environmental surveys including RADON. We are able to offer advice on the reduction of Radon, which is a colourless and odourless radioactive gas, and can undertake remediation measures where concentration levels are above the recommended maximum. Please speak to us about any additional testing you may require.

Sound Insulation and Environmental Noise Measurement

Guernsey Building Regulations demand that new domestic buildings have a minimum level of sound insulation, as detailed in Technical Standard E "Resistance to the passage of sound".

Sound insulation

Where properties are attached, sound insulation is very important for the comfort of occupants. Building Regulations require minimum insulation standards for separating elements such as walls and floors; Technical Standard E gives details of these acceptable levels and approvedtesting methods. AFM can offer  a fully compliant testing service using Institute of Acoustics (TechIOA) technicians. 

Environmental noise measurement

Before any external noise generating equipment is installed such as a/c condensers, heat pumps or  extract fans, there’s usually a need for planning approval. This often requires details of sound levels and proposed methods of noise attenuation.  As part of any  assessment, AFM can undertake environmental noise measurements to identify existing background levels as well as actual noise generated after installation.

With all our testing, our aim is to help clients achieve the required standards with an efficient, cost effective  and easy to use service.

Thermal Imaging Surveys

With our state of the art cameras, we can produce thermal image surveys to help determine insulation performance in buildings.

Is your building losing heat?  

Our state of the art thermal imaging camera is able to detect any heat loss or air leaks within the fabric of your building.  

Why not let us conduct a survey and offer suitable solutions to any heat loss problems you may have.
