Kerbside weight or revenue weight

Don't forget that the 85% is only a recommendation as a sensible ratio between tow car and caravan. My understanding is that the 85% is of the actual weight of the car.

Thanks for that David. It does get quite confusing with kerbside weight not seeming to have a definitive definition. My V5 uses terms like Revenue Weight and Mass in Service, but kerbside weight appears no where.

Thanks again for your help.

There are numerous threads on this subject on the forum. The 85% recommendation is of the kerb weight of the car, not the gross vehicle weight. Kerb weight (more or less the unladen weight) is difficult to establish but will usually be found in the car manufacturer's literature somewhere. 

It's to give worse case scenario, 85% of kerb weight and fully laden caravan weight.

I'm surprised not to find this guidance in the club's Advice & Training section but the RAC state it well.

Revenue weight only has any significance for vehicles registered as commercial vehicles.

Kerbweight isn't documented anywhere. If you use the Mass in Service value on the V5c you will be on the safe side as that is almost invariably less than the kerbweight.

The most accurate value which is close to kerbweight is "actual mass", but that is only documented as item 13.2 in the type approval Certificate of Conformity and that is rarely passed on to the owner in the UK. Otherwise, if you want an accurate value, you will just have to put the car on a weighbridge.

Thanks for the contributions. It is curious that everywhere kerbside weight is referred to in calculations to determine PEP, but there's no definitive documentation.
