A habitation check is a detailed examination of the living areas of your motorhome or caravan. A specialist motorhome engineer should carry out the inspection. 

Selecting a reputable service engineer or workshop to conduct your motorhomes annual habitation service can be quite daunting. Fortunately, there is a collaboration by the National Caravan Council, The Caravan and Motorhome Club, and The Camping and Caravanning Club.

This collaboration has resulted in the creation of the AWS (Approved Workshop Scheme). To be a part of the scheme requires the workshop to pass a rigorous annual inspection.

An independent inspector carries out these inspections to comply with strict standards. Bearing all this in mind will give you complete peace of mind when having your annual motorhome habitation service.

The technicians must also have formal qualifications and comply fully with the industry's code of practice. The habitation service must follow a set procedure and a highly detailed inspection plan.

It must cover dangers such as ventilation systems, gas systems and fire risk.  It also covers problem areas like electrical systems, water systems, bodywork and damp.

After the habitation service is completed, you will receive a full detailed report it will contain all observations of any problems that have been identified and the action that is required for the findings to be rectified.

The first thing you need to do, is contact a workshop service engineer that is trusted to complete the service. Here are some points that might help you to make your decision. 

What Is Checked During Motorhome Servicing

Fixed Workshop:

Regardless of the weather conditions, your motorhome habitation service can be carried out in a fixed workshop. A workshop will also have plenty of space to stock items that might be required for your motorhome habitation service. 

Some garages and motorhome dealers will send you yearly service reminders for your habitation service. You would need to take your motorhome to the workshop, you would need to check the location, as they might not be close to your home.

Electrical Systems:

he engineer will thoroughly check and assess all external and internal lights on your vehicle for any faults. All sockets are tested, the engineer will do this using a loop check. A loop check sends a signal down the socket to verify and ensure it is correctly wired.

Also included in the check of the electrical systems is the consumer unit, the refrigerator operation, the battery, television socket and any other electrical system that might require checking.

An RCD (residual current device) check is also conducted; this check involves making sure the RCD will trip within a set time.The miniature circuit breakers are also checked to ensure that they are correct for the appliances that you have in your motorhome.

Gas Systems:

The engineer will use a manometer to check your gas supply for any gas leaks that your motorhome might have. Every gas appliance in your motorhome will also be checked to make sure they are all working efficiently and correctly.

These checks will include turning the appliances on, to ensure they are working correctly. The appliances will consist of the refrigerator the water heater and your motorhomes heating system.

All vents in your motorhome will be thoroughly checked to ensure they are clear. All the appliances will then be turned off at the gas isolator taps. 

If the flame-failure device cuts in, this will mean that the test has been passed. A second test is the Carbon Monoxide (CO2) test. All the gas appliances will be turned on, and a flue gas analyser will run for a minimum of 15 minutes, all the windows and doors are kept closed during this test. This test will show the quality of the air in your motorhome. All results are then recorded, and you will be informed once these checks have been carried out.

Water Systems: 

All taps in your motorhome will be individually checked for any leaks, the engineer will also check your motorhomes waste-water outlet to make sure there are no blockages. The engineer will inspect the vehicle's toilet to make sure that the valve seal is lubricated well and the battery-operated flush is working as it should be. 

If your motorhome is installed with an Alde wet heating system, the water and ethylene glycol antifreeze must be a 50/50 mix.

The engineer will check this is correct by using a portable refractometer. The antifreeze mix in the header tank must be 10mm above the minimum and not at maximum.It is also recommended that the antifreeze in your motorhome is changed every two years.


The engineer will conduct a full check of all blinds, windows and doors on your vehicle is operating smoothly. The engineer will make general observations of the whole of the motorhomes bodywork.

The roof will be inspected visually. A damp check will be conducted around the inside of your motorhome. If the reading is 0-15%, it means there are no concerns. If the reading is 15-20%, a recheck will be required within three months.

If the reading is above 20%, it means that immediate attention is required, this, is because it highlights an area of the motorhome has water ingress.The motorhome service technician should give you a damp report on completion of the service.

Fire Safety:

The CO detector and smoke alarm will be tested and are not passed their date of replacement. If you have a fire extinguisher in your motorhome the expiry date will be checked, the housing unit will also be inspected to make sure it is secure.
