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 youโ€™ll need is a towbar. But, it is important to check the regulations for heating installation in the UK before booking anything. Towbars canโ€™t 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 youโ€™ve 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? Letโ€™s go over the explanation simply.

Whatโ€™s 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 arenโ€™t the same, things might not work out.

Older vehicles (made before August 1998) donโ€™t legally require a type-approved towbar. But itโ€™s still a smart move to use one thatโ€™s tested and trusted – your safety depends on it.

Why Professional Fitting Matters

You canโ€™t treat a towbar as you might a shelf – it is connected to your carโ€™s frame, wiring and occasionally the bumper. Thatโ€™s 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 youโ€™re browsing online for โ€œa motor mover fitted near meโ€, itโ€™s 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 carโ€™s 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.

Thatโ€™s why when searching for โ€œtowbar fitting near meโ€, itโ€™s smart to pick a provider who handles the complete wiring and tests everything before you drive away.

How Much Weight Can You Tow?

You canโ€™t 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 itโ€™s also illegal.

Breakaway Cables & Safety Chains

This kind of maintenance may look small, but it can really help. When your trailer breaks loose while youโ€™re 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 doesnโ€™t 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 whatโ€™s 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 youโ€™re missing this plate or using the wrong one itโ€™s a fineable offence.

Insurance and Notifications

You should always notify your car insurance provider when a tow bar is added. Itโ€™s seen as a modification, even if it’s professionally installed. If you donโ€™t, your insurance might not cover you if something goes wrong.

The same goes if youโ€™ve recently had a motor mover fitted near me – notify your insurer to stay protected.
