Whether you’re towing a caravan, trailer, horsebox or simply carrying bikes on a towbar-mounted rack, choosing the right towbar is essential for safety, performance and long-term value. Unfortunately, many motorists focus only on price and overlook factors that can affect their vehicle, insurance and towing experience.
At Ultimate Towbars, we’ve fitted thousands of towbars across the UK and have seen the same mistakes made time and time again. This guide explains the ten most common mistakes people make when buying a towbar – and how you can avoid them.
1. Choosing the Cheapest Towbar Instead of the Right One
Everyone likes to save money, but the cheapest quote isn’t always the best value.
Some installers may use lower-quality components, omit vehicle coding, or fit universal electrics rather than vehicle-specific wiring kits. While this may reduce the upfront cost, it can lead to problems with parking sensors, trailer stability systems and manufacturer safety features.
A professionally fitted, high-quality towbar offers greater reliability, durability and peace of mind.
Top Tip: Ask exactly what’s included in your quote before comparing prices.
2. Buying the Wrong Type of Towbar
Not all towbars are the same.
The three most common types are:
- Fixed flange towbars – ideal for frequent towing and compatible with many accessories.
- Fixed swan neck towbars – popular for modern vehicles and a cleaner appearance.
- Detachable towbars – can be removed when not in use, maintaining the vehicle’s appearance.
- Retractable towbars – fold away beneath the vehicle for maximum convenience.
Choosing the wrong style can leave you paying for features you don’t need—or wishing you’d selected a different option.
Think about how often you’ll tow and whether appearance is important.
3. Forgetting About the Electrics
Many buyers focus solely on the towbar itself and overlook the electrical system.
Your electrics control:
- Trailer lights
- Indicators
- Brake lights
- Reverse lights
- Fog lights
- Caravan power supply
- Battery charging
- Electronic Trailer Stability
Most modern vehicles benefit from dedicated vehicle-specific wiring kits that integrate with the car’s electronics.
Choosing the correct electrical kit helps ensure all safety systems continue to operate correctly.
4. Not Checking Your Vehicle’s Towing Capacity
A towbar doesn’t increase what your vehicle can legally tow.
Every vehicle has a maximum towing capacity set by the manufacturer.
Before buying a towbar, always check:
- Maximum towing weight
- Nose weight
- Gross Train Weight (GTW)
Exceeding these limits can affect handling, invalidate insurance and may even be illegal.
5. Ignoring Vehicle Coding
Many newer vehicles require electronic coding after a towbar has been installed.
Vehicle coding allows systems such as:
- Trailer Stability Assist
- Parking sensors
- Blind spot monitoring
- Adaptive cruise control
- Rear fog light switching
- Manoeuvre Braking
to work correctly while towing.
Skipping this step may prevent important safety features from functioning as intended.
6. Buying Without Thinking About Future Needs
Many customers buy a towbar purely for today’s requirements.
A year later they decide to:
- Buy a caravan
- Upgrade their trailer
- Purchase a towbar-mounted bike rack
- Tow a larger load
Choosing a slightly more versatile towbar now can save replacing it later.
Consider how your towing needs may change over the next few years.
7. Attempting a DIY Installation
Although DIY towbar fitting kits are available, fitting a modern towbar is rarely straightforward.
Modern vehicles often require:
- Removal of bumpers
- Precise torque settings
- Electrical integration
- ECU programming
- Safety testing
Incorrect installation can compromise vehicle safety and may invalidate warranties or insurance.
Professional installation ensures the towbar performs exactly as intended.
8. Forgetting About Bike Rack Compatibility
Many people aren’t buying a towbar for towing at all.
Towbar-mounted bike racks have become one of the most popular reasons for installing a towbar.
However, not every towbar works with every bike rack.
If transporting bikes is your priority, discuss compatibility before installation.
9. Not Considering Vehicle Appearance
For many drivers, appearance matters.
A permanently visible towbar may not suit every vehicle.
If aesthetics are important, consider:
- Detachable towbars
- Retractable towbars
- Swan neck designs
These options keep your vehicle looking cleaner when the towbar isn’t in use.
10. Choosing an Installer Based Only on Price
Perhaps the biggest mistake is selecting an installer solely because they’re the cheapest.
A reputable installer should provide:
- High-quality towbars
- Professional installation
- Vehicle-specific electrics
- Coding where required
- Warranty on parts and labour
- After-sales support
An experienced installer will also advise which towbar best suits your vehicle and intended use.
Frequently Asked Questions
Which towbar is best?
The best towbar depends on your vehicle and how you intend to use it. Frequent towing may suit a fixed towbar, while occasional users often prefer detachable or retractable options.
Do all modern cars need coding after a towbar is fitted?
Many do, although requirements vary by manufacturer and model. A professional installer can advise whether coding is necessary.
Can I fit a towbar myself?
While it’s possible on some vehicles, modern cars often require specialist tools, electrical integration and programming. Professional installation is generally recommended.
Does fitting a towbar affect my warranty?
When installed correctly using quality components, a towbar should not automatically invalidate your vehicle warranty. Always choose an experienced installer and ensure the towbar is approved for your vehicle.
How long does towbar installation take?
Most installations are completed within three to four hours, although some vehicles requiring additional coding or more complex fitting may take longer.
