    Motorhome Weight Checker. Check If Your Motorhome Is Overloaded

    Use the RoamWorthy motorhome weight checker to find out if your motorhome is within its legal weight limits. Enter your motorhome's registration or key weight figures to get an instant payload and gross vehicle weight analysis.

    This free tool checks your motorhome's Mass in Running Order (MIRO) against the Maximum Technically Permissible Laden Mass (MTPLM) to calculate available payload. It also checks whether you need a C1 licence category based on the vehicle's gross weight. Covers all major motorhome manufacturers including Bailey, Swift, Auto-Trail, Elddis, Bürstner, Hymer, and Rapido.

    Frequently Asked Questions

    It depends on the motorhome's Maximum Authorised Mass (MAM/GVW). Up to 3,500kg requires a standard Category B car licence. 3,500-7,500kg requires a Category C1 licence. Over 7,500kg requires a full Category C HGV licence.

    Only if the motorhome's GVW exceeds 3,500kg. Many motorhomes weigh 3,500-4,500kg, which puts them in C1 territory. If you passed your driving test before 1 January 1997, you likely already have C1 entitlement. Check the categories on the back of your photocard.

    Yes. A standard Category B (car) licence covers vehicles up to 3,500kg GVW. Many panel van conversions and smaller coachbuilts fall at or below this limit.

    Not on a standard post-1997 car licence. You'd need C1 entitlement. Drivers who passed before 1 January 1997 often have C1 automatically. Otherwise, you'll need to take the C1 test or consider a lighter motorhome.

    Very likely. Most UK drivers who passed before 1 January 1997 were granted C1 entitlement automatically (grandfather rights). Check the back of your photocard for the C1 category. This allows you to drive vehicles up to 7,500kg.

    C1 entitlement requires a medical renewal every 3 years from age 70. You must complete a D2 application and D4 medical form. If you don't renew, you lose C1 and revert to Category B (up to 3,500kg).

    A C1 licence typically costs £1,000-£2,000 including training, medical, and test fees. Training usually takes 3-5 days. Some intensive courses combine training and test.

    GVW (Gross Vehicle Weight) or MAM (Maximum Authorised Mass) is the maximum legal weight of the motorhome when fully loaded, including passengers, fuel, water, and belongings. It determines which licence category you need.
