Understanding MOT and Motorhomes: A Guide
Discover everything you need to know about MOT tests for motorhomes in the UK. Learn requirements, insurance information, preparation tips, common issues, and benefits to ensure your motorhome stays roadworthy and compliant.

Motorhomes are increasingly popular as versatile and comfortable vehicles for both travel and living. However, owning a motorhome comes with responsibilities, including ensuring that it is safe and roadworthy. One key aspect of motorhome maintenance in the UK is the MOT test. This article provides a comprehensive guide to understanding MOT requirements for motorhomes, what the test entails, and how to prepare your motorhome for a successful MOT.
What is an MOT?
An MOT (Ministry of Transport) test is a mandatory annual inspection required for most vehicles in the UK over three years old. The purpose is to ensure that vehicles meet road safety and environmental standards. For motorhomes, this means evaluating key components such as brakes, lights, emissions, and structural integrity.
Do Motorhomes Require an MOT?
Yes, motorhomes require an MOT if they are over three years old and weigh up to 3,500 kg (category IV vehicles). Larger motorhomes (over 3,500 kg) fall into category VII and have slightly different requirements. This ensures that motorhomes remain safe for use on the road.
What Does an MOT Test for Motorhomes Include?
The MOT for motorhomes is like that for regular vehicles. However, there may be extra checks because of the motorhome’s size and design. Here’s what the test typically involves:
1. Lights and Electricals
- Functionality of headlights, brake lights, indicators, and hazard lights.
- Proper alignment of headlights to avoid dazzling other drivers.
2. Brakes and Suspension
- Inspection of brake pads, discs, and overall braking efficiency.
- Suspension components are checked for wear and tear.
3. Emissions
- Testing exhaust emissions to ensure compliance with environmental standards.
- Inspection of the exhaust system for leaks or damage.
4. Tyres and Wheels
- Tread depth and condition of tyres (minimum tread depth: 1.6 mm).
- Structural integrity of wheels and proper inflation of tyres.
5. Bodywork and Structure
- Ensuring that the motorhome’s body is free of excessive corrosion or damage.
- Checking for secure attachment of doors, windows, and other external components.
6. Mirrors and Visibility
- Functionality and positioning of mirrors.
- Clean and undamaged windscreen with no significant obstruction in the driver’s view.
7. Weight and Load
- Verification that the motorhome’s weight falls within legal limits.
- Ensuring the vehicle is not overloaded.
MOT Classes for Motorhomes
Motorhomes are classified into categories for MOT purposes based on weight and size:
- Class IV: Motorhomes weighing up to 3,500 kg.
- Class VII: Motorhomes weighing between 3,500 kg and 5,000 kg.
It's essential to know your motorhome’s category to book the appropriate MOT test.
Where Can You Get an MOT for a Motorhome?
Not all MOT testing centers can accommodate motorhomes, especially larger models. It’s crucial to find a center equipped with suitable facilities, such as higher garage doors and larger vehicle lifts. Specialized motorhome service centers are often the best option.
Preparing Your Motorhome for an MOT
To improve your chances of passing the MOT test, follow these preparation steps:
Conduct a Pre-MOT Check:
- Inspect lights, tyres, and fluid levels.
- Ensure all doors and windows operate smoothly.
Clean the Motorhome:
- Remove excess dirt from the exterior and undercarriage.
- A clean motorhome can make inspections easier for testers.
Address Known Issues:
- Fix any minor faults, such as broken bulbs or worn wiper blades, before the test.
Check Documentation:
- Have your vehicle’s logbook (V5C) and previous MOT certificates handy.
Common Reasons Motorhomes Fail an MOT
Motorhomes often fail MOT tests due to the following issues:
- Faulty lighting or electricals.
- Brake system inefficiencies.
- Excessive emissions or exhaust system damage.
- Tyre wear below the legal limit.
- Structural corrosion or damage.
What Happens If Your Motorhome Fails the MOT?
If your motorhome fails its MOT, you’ll receive a failure certificate detailing the reasons. You must repair the faults before retesting. In some cases, minor issues (advisories) can be resolved without a retest, but critical faults require immediate attention.
Cost of an MOT for Motorhomes
The cost of an MOT test varies but typically ranges from £40 to £60 for motorhomes in Class IV. Larger motorhomes in Class VII may incur higher fees. Some centers may offer discounts or packages, including servicing.
