A guide to motorhome showroom buying.

Whether you are preparing for a summer tour of the Highlands or winterising your vehicle, professional servicing covers everything from gas safety to engine reliability. This guide outlines what to expect when hiring a motorhome specialist and the typical costs involved in 2025.

What Does the Work Involve?

• Habitation Check: A comprehensive inspection of the living area, including gas tightness tests, electrical safety (12V and 230V), and water system functionality.
• Damp Inspection: Using a calibrated moisture meter to check for water ingress in the walls, floor, and ceiling, which is the most common "silent killer" of UK motorhomes.
• Mechanical Servicing: Standard engine maintenance including oil changes, filter replacements, and brake inspections on the base vehicle chassis.
• Gas Safety: Testing regulators, hoses, and appliances (fridges, hobs, heaters) for leaks and correct combustion.
• Chassis & Running Gear: Checking corner steadies, tyres (including age/cracking), and underbody integrity.
• System Diagnostics: Troubleshooting faults in solar arrays, inverters, leisure batteries, and complex HVAC systems.

Typical Costs

Prices vary based on the size of the motorhome (coachbuilt vs. van conversion) and whether you choose a mobile technician or a fixed workshop. Most reputable UK specialists now charge rates that reflect the high level of training required for dual-trade (automotive and domestic) competency.

Note: Prices usually include VAT but exclude the cost of specialised parts, such as replacement water pumps, gas regulators, or bespoke window seals which can be expensive for older models.

How Long Does It Take?

• Standard Habitation Check: 3 to 4 hours. This is a meticulous process that cannot be rushed if gas safety is to be verified correctly.
• Full Mechanical Service: 2 to 5 hours depending on the accessibility of filters and the condition of the fluids.
• Solar Panel Installation: 4 to 6 hours, including cable routing and controller configuration.
• Major Damp Remediation: 1 to 4 weeks. These jobs often require stripping interior furniture and drying out the structure before rebuilding.

DIY or Professional?

While basic cleaning and minor cosmetic repairs are suitable for DIY, the core systems of a motorhome require professional intervention. In the UK, gas work should ideally be handled by a technician who is Gas Safe registered with a specific "LPG/Motorhomes" qualification.

Warning: Attempting to repair 230V electrical systems or gas appliances yourself can void your insurance and, more importantly, put your life at risk from fire or carbon monoxide poisoning.

Furthermore, if your motorhome is under warranty, you must have it serviced by an approved workshop to keep the guarantee valid. Professional damp reports are also essential documentation when the time comes to sell or part-exchange your vehicle.

Choosing the Right Tradesperson

Not all garages are equipped to handle motorhomes. You need a specialist who understands the unique stresses placed on leisure vehicles. Look for the following:

• AWS Accreditation: The Approved Workshop Scheme (AWS) is a joint venture between the NCC, The Caravan and Motorhome Club, and The Camping and Caravanning Club. It is the gold standard for UK motorhome servicing.
• Experience with your Brand: Some systems (like Alde heating or specific Italian electrical units) require brand-specific diagnostic tools.
• Insurance: Ensure they have public liability insurance and "Road Risks" insurance if they are driving your vehicle.

Questions to ask:

• Are you a member of the Approved Workshop Scheme (AWS)?
• Do you provide a full written damp report with moisture percentage readings?
• Will this service maintain my manufacturer's warranty?
• Do you use genuine OEM parts for the chassis service?

UK Regulations

• MOT: Like any vehicle, motorhomes over 3 years old require an annual MOT. Note that larger motorhomes (over 3,500kg) may require a Class 7 MOT rather than the standard Class 4.
• Gas Safety (LPG): While not a legal requirement for private owners (unlike landlords), it is a requirement for most insurance policies and many UK campsites.
• Weight Limits: It is your responsibility to ensure the vehicle does not exceed its MTPLM (Maximum Technologically Permissible Laden Mass). Professional weigh-ins are often part of a comprehensive service.

Common Problems

• Water Ingress: Sealants degrade over time due to UV exposure and vibration. If caught early, a reseal is cheap; if left, it can rot the frame.
• Leisure Battery Failure: Often caused by "deep discharging" during winter storage. A specialist can test the health and "SOH" (State of Health) of your batteries.
• Tyre Degradation: Motorhome tyres often have plenty of tread but fail due to age-related sidewall cracking. UK safety guidelines recommend replacing tyres every 5-7 years regardless of mileage.
• Seized Brakes: Common in motorhomes that sit idle for long periods. Regular servicing ensures calipers and drums are cleaned and lubricated.
