What Are the Legal Requirements for Towbar Fitting in the UK?
27 May 2025 by joeadm
If you plan to use a caravan, trailer or your bike rack, the most important item youโll need is a towbar. But, it is important to check the regulations for heating installation in the UK before booking anything. Towbars canโt be added simply by getting the parts and bolting them in place. You need to follow certain rules to guarantee your car is safe on the road and legal.
Maybe youโve been searching for a towbar fitting near meย or comparing mobile installers, but do you know what laws are involved once that towbar is attached? Letโs go over the explanation simply.
Whatโs the Law on Towbars in the UK?
Almost every car in the UK made since 1998 must have a type-approved towbar. As such, the towbar you are given is suited for your particular vehicle after a successful test. It works just like fitting a key to a lock, when the parts arenโt the same, things might not work out.
Older vehicles (made before August 1998) donโt legally require a type-approved towbar. But itโs still a smart move to use one thatโs tested and trusted – your safety depends on it.
Why Professional Fitting Matters
You canโt treat a towbar as you might a shelf – it is connected to your carโs frame, wiring and occasionally the bumper. Thatโs why a proper installation of the air conditioner is required.
A professional mechanic knows exactly where to secure the towbar, how to wire it correctly and how to maintain your vehicle warranty. Home improvements might look affordable at first, but you could end up spending even more by making errors.
If youโre browsing online for โa motor mover fitted near meโ, itโs often a good sign if that installer also fits towbars – it shows they understand towing systems inside and out.
Electrical Connections: Not Just Plug and Play
Once the towbar is fixed, you need to set up wiring to your carโs light system. Why? You should provide matching brake lights, indicators and signals on your trailer or caravan for your safety.
You might use a 7-pin or 13-pin plug, but remember to make certain everything is functional while on the road. Poorly-connected wiring may prevent your trailer from showing when you break or turn, risking your safety and following the law.
Thatโs why when searching for โtowbar fitting near meโ, itโs smart to pick a provider who handles the complete wiring and tests everything before you drive away.
How Much Weight Can You Tow?
You canโt just hook up any size trailer to your car – every vehicle has a towing limit. This includes:
- Braked trailers (with their own brakes) – You can tow more weight if the trailer has its braking system.
- Unbraked trailers – These must weigh under 750kg or no more than half the weight of your car.
Check your car’s manual or VIN plate (usually located under the hood) for the maximum towing weight. Exceeding the limit can damage your vehicle, and itโs also illegal.
Breakaway Cables & Safety Chains
This kind of maintenance may look small, but it can really help. When your trailer breaks loose while youโre driving, the breakaway cable or safety chain prevents it from resulting in a crash.
- Breakaway cable – Required if your trailer has brakes.
- Safety chain – Needed if your trailer doesnโt have brakes.
These are legal must-haves and a great example of why using a trained professional is so important.
If you’re also looking to upgrade your caravan setup, finding a quality motor mover fitter can be helpful. As many of these also handle safety accessories, and know what to look for.
Do You Need Towing Mirrors?
If the caravan or trailer is wider than your car, then yes UK law says you must use towing mirrors. They give you a better view of whatโs behind you and help you stay aware of your surroundings. Without them, you risk:
- A ยฃ1,000 fine
- 3 points on your licence
- Reduced safety while driving
They’re inexpensive and can be easily clipped on and removed, so there’s no reason to skip this step.
What About Number Plates?
Your trailer must have a number plate that matches the one on the car towing it. It needs to be clear, readable, and lit up at night. This helps other drivers and road cameras identify the vehicle correctly.
If youโre missing this plate or using the wrong one itโs a fineable offence.
Insurance and Notifications
You should always notify your car insurance provider when a tow bar is added. Itโs seen as a modification, even if it’s professionally installed. If you donโt, your insurance might not cover you if something goes wrong.
The same goes if youโve recently had a motor mover fitted near me – notify your insurer to stay protected.
