UK Towing Capacity Calculator

How to Use the UK Towing Capacity Calculator: A Complete Guide

Understanding your vehicle's towing capacity is crucial for safe and legal towing in Britain. Our calculator simplifies complex DVSA regulations into an easy-to-use tool. Here's how to make the most of it:

Step 1: Know Your Vehicle

Start by selecting your vehicle type. Cars typically have lower capacities than 4x4s or vans. The engine size field requires your vehicle's exact engine capacity in litres - find this in your owner's manual or V5C registration document.

Step 2: Trailer Specifications

Choose between braked and unbraked trailers. In the UK, unbraked trailers max out at 750kg. Braked trailers require proper coupling and can handle heavier loads, but must comply with BS AU 200b standards.

Step 3: Load Weight

Input your expected load weight in kilograms. Remember this includes both trailer weight and cargo. Exceeding your vehicle's Gross Train Weight (GTW) is illegal and dangerous.

Key Factors in UK Towing

• B+E Licence Requirements: For trailers over 3,500kg MAM
• 85% Rule: Recommended weight ratio for caravans
• MOT Checks: Legal requirements for tow bars and electricals

Safety First

While our calculator uses DVLA guidelines, always check your vehicle's specific towing capacity in the owner's manual. Consider:

• Proper load distribution
• Tyre pressures and condition
• Breakaway cables and safety chains

Regularly update your calculations if modifying your vehicle or changing loads. When in doubt, consult a certified towing specialist or your vehicle manufacturer.
