Why Compare Trailer Insurance?
Theft Is The Real Threat
Unhitched trailers are towed away in minutes from yards and driveways. Clean Green Cars introduces you to specialist brokers who price theft risk and security properly.
Your Car Policy Has A Gap
A towing vehicle's policy usually covers third-party damage only, not the trailer for theft or fire. Clean Green Cars introduces you to specialist brokers who close that gap.
Cover Built Around Your Trailer
Plant, catering, car-transporter and goods trailers carry different risks. Clean Green Cars introduces you to brokers who specialise in trailer cover, not a generic add-on.

Cover Levels Explained
Pick third party only and a stolen trailer leaves you thousands out of pocket. Here's what each level could include.
| Feature | Comprehensive | Third Party, Fire & Theft | Third Party Only |
|---|---|---|---|
| Theft of the trailer | Usually included | Usually included | Not covered |
| Fire damage | Usually included | Usually included | Not covered |
| Accidental damage to your trailer | Usually included | Not covered | Not covered |

| Trailer contents or carried load | Often optional | Often optional | Not covered |
| Recovery or replacement after theft | Often optional | Sometimes optional | Not covered |
| European towing cover | Often optional | Often optional | Sometimes optional |
Please note that policy features, benefits, terms and conditions vary among insurance providers, so always check the policy wording.
Cover Tip: If your trailer carries tools or a load, ask whether contents are insured separately. Many trailer policies cover the trailer itself but treat the goods on it as a separate question, which the exclusions section below sets out in more detail.
What May Not Be Covered
A single exclusion can turn a stolen-trailer claim into a refusal. Here's what trailer cover typically may not include.
Standard Exclusions
- Trailer left unsecured - Theft claims may be declined if an approved hitch lock or wheel clamp was not fitted while the trailer was unattended, as the cost factors section explains.
- Wear, tear and corrosion - Gradual deterioration, rust or tyre perishing is maintenance, not an insured event, so a policy may not pay for it.
- Overloading beyond rated weight - Damage caused by loading a trailer above its plated maximum may not be covered and could affect a claim.
Important Limitations
- Goods carried on the trailer - The load itself is often excluded unless contents cover is added, which the extras section above covers in more detail.
- Use not declared - Hire and reward or commercial haulage use may not be covered if the trailer was insured for private use only.
- Unattended away from a secure base - Some policies limit cover when a trailer is left overnight away from its declared storage location.
Extras Worth Considering
Skip breakdown recovery and a roadside failure can strand a loaded trailer for hours. These extras could be worth considering.
May help cover tools, equipment or goods carried on the trailer, which the base policy often excludes.
May help cover the cost of hiring a trailer while a stolen or damaged one is replaced, so work does not stop.
May extend protection while towing abroad for a set number of days, useful for cross-Channel jobs.
May help recover both the towing vehicle and a loaded trailer if you break down mid-journey.
What Affects The Cost?
Underdeclare where your trailer is kept and a theft claim could be cut for misrepresentation. Here's what shapes the price.
| Key Factor | Impact on Your Price |
|---|---|
| Trailer value and type | A plant or car-transporter trailer typically costs more to insure than a small box trailer because replacement values and theft appeal are higher. |
| Security fitted | Owners with a Thatcham-rated hitch lock and wheel clamp often see lower quotes than those relying on the coupling alone. |
| Where it is kept overnight | A trailer behind locked gates or in a yard usually prices better than one left on a driveway or roadside, as the exclusions above reflect. |
| Forensic or CESAR marking | A marked trailer is easier to trace and recover, so brokers may price it as a lower theft risk. |
| Use of the trailer | Private occasional use generally costs less than daily commercial or hire and reward use, which carries more exposure. The towing vehicle's own cover, such as van insurance, can also affect the overall picture. |
The quotes you get will depend on your own details, the trailer's value and how it's secured.
Price Insight: Security is the cost lever you control most. The factors above show what drives the price, and a Thatcham-rated hitch lock plus a wheel clamp often moves a trailer quote more than any other single change an owner can make.
Ways To Cut Your Premium
Renew on autopilot and a trailer policy can drift above a fresh comparison. Here's how to cut what you pay.
Fit Visible Security
A Thatcham-rated hitch lock plus a wheel clamp is the change brokers reward most, because it directly cuts theft risk.
Store It Out Of Sight
Moving a trailer behind locked gates or into a yard overnight can lower the quote and supports a future claim.
Mark And Register It
A CESAR or forensic-marked trailer is harder to sell on and easier to recover, which brokers often price as reduced risk.
Bundle Recovery Cover
Adding breakdown cover that includes the trailer can be cheaper than a separate roadside policy if you tow often.
Compare Before Auto-Renewal
Trailer premiums can drift upward at renewal even when nothing about the trailer or its security has changed.
Saving Tip: Fit and declare a CESAR or forensic-marked tag before you compare, not after. Brokers price the discount into the quote up front, so marking the trailer first often beats asking for a reduction at renewal. Pair it with breakdown cover so a stranded load never becomes a separate emergency.

What Our Expert Says
The builder who leaves a loaded plant trailer on the verge overnight and the weekend owner who tows a car-transporter twice a year face the same core problem. A trailer is easy to take and hard to trace. An unhitched flatbed can be coupled and gone in under a minute, and once it changes hands it rarely comes back.
A trades operator with a daily box trailer worries about losing the tools as much as the trailer, while the occasional horsebox owner usually needs a different product entirely. The recurring misunderstanding across all of them is the same: the towing vehicle's policy is assumed to cover the trailer. It typically extends only to third-party damage the trailer causes, not theft, fire or damage to the trailer itself. Standalone cover closes that gap, and forensic marking such as the CESAR scheme both deters thieves and helps police return a recovered trailer.
One detail outweighs the rest. Where the trailer sleeps shapes both the price and whether a future claim is paid, more than the trailer's value does. A clamped trailer behind locked gates is a different risk to one on a roadside, so be precise about that on the form.

Common Questions
Do I Need Insurance For A Trailer In The UK?
Trailer insurance is not a legal requirement in the UK, but a towing vehicle policy usually covers only third-party damage. Without standalone cover, a stolen or damaged trailer is your own loss.
Does Trailer Insurance Cover Theft?
Comprehensive and third party fire and theft trailer policies usually include theft, the biggest risk trailers face. Claims can still be declined if a required hitch lock or wheel clamp was not fitted.
Does My Car Insurance Cover My Trailer?
Most car and van policies extend only to third-party damage the trailer causes while attached. They typically do not cover the trailer itself for theft, fire or accidental damage, which is why standalone cover exists.
How Much Does Trailer Insurance Cost?
Trailer cover depends on the trailer's value, type, security and where it's kept. A small box trailer is far cheaper to insure than a plant or car-transporter trailer with a high replacement value.
What Security Reduces Trailer Insurance Costs?
A Thatcham-rated hitch lock, a wheel clamp and CESAR or forensic marking are the changes brokers reward most. Storing the trailer behind locked gates overnight also helps the quote.
What Types Of Trailer Can Be Insured?
Specialist brokers can cover plant, box, flatbed, car-transporter and general goods trailers. Horse trailer owners should compare horsebox insurance instead, as it is built for animal transport.
Does Trailer Insurance Cover Towing In Europe?
European towing cover is usually an optional extra rather than standard. If you tow across the Channel, confirm the number of days included before you rely on it.
