How to Buy a Used Caravan: The Complete Checklist
Before buying any used caravan, check for damp (the biggest risk), verify the service history, confirm your car can tow it safely, and inspect tyres, brakes, and chassis condition. A thorough pre-purchase inspection costs far less than discovering problems after you've paid.
- Damp is the single biggest risk. Always check with a meter
- Run our free towing calculator to confirm your car can handle it
- Ask for habitation check certificates and damp reports

The used caravan buyer's checklist
1. Damp check
The most critical test. Check all walls, floor, ceiling, and around every window and roof light with a damp meter. Any reading above 15% needs investigation. Pay special attention to the front panel, rear panel, and around the toilet/shower area.
What is a damp check? →2. Service history
Ask for annual habitation check certificates and damp test results. A consistent history of annual checks shows the caravan has been maintained. Gaps in service history are a warning sign. Particularly missing damp reports.
Service history explained →3. Habitation check
An annual habitation check covers gas safety, electrical safety, ventilation, damp, and general condition. It is the caravan equivalent of an MOT. A current certificate shows the caravan is safe to use. An expired or missing check means you may need to budget for immediate servicing.
What is a habitation check? →4. Weight and towing suitability
Check the MTPLM on the VIN plate and compare it to your car's towing capacity. Run the 85% rule: your car's kerbweight × 0.85 should exceed the caravan's MTPLM. Also check payload (MTPLM minus MiRO). Aim for at least 150kg usable.
Check your towing match →5. Tyres, brakes, and chassis
Check tyre age (date code on sidewall. Replace if over 5 years old regardless of tread). Test the handbrake on a slope. Look for chassis corrosion, particularly around the A-frame and axle mounting points. Check the hitch head for wear and that the breakaway cable is present.
6. Signs of water ingress
Beyond the damp meter: look for staining on ceilings and walls, wallpaper peeling, musty smells, soft spots in the floor, and discolouration around windows. Check the front panel for crazing or cracks. This is where water often enters. Run your hand along the underside of overhead lockers.
Damp check glossary →7. Can your car tow it?
Use our free towing calculator to check the 85% rule, braked towing limit, and GTW simultaneously. Enter your reg to instantly look up your car's kerbweight and towing capacity. Many buyers fall in love with a caravan before checking their car can handle it.
Look up your car by reg →8. Documentation
Check for: CRiS registration document, owner's handbook, habitation check certificates, gas safety certificate (current), electrical safety certificate, warranty documentation, and any receipts for major work. Run a CRiS check to verify the seller is the registered keeper.
Buying from a dealer vs private seller
From a dealer
- Consumer Rights Act protection (up to 6 years)
- Dealer warranty often included
- Pre-delivery inspection standard
- Finance and part-exchange options
- Higher prices than private
Private seller
- Often cheaper than dealer prices
- Can negotiate directly with owner
- No Consumer Rights Act protection
- No warranty unless separately arranged
- Budget for independent inspection
Questions to ask the seller
- When was the last habitation check, and can I see the certificate?
- Has it ever had a damp reading above 15%? Can I see the damp reports?
- Has any bodywork, panel, or window seal been replaced or repaired?
- Is there a full service history with dates and workshop details?
- What is the actual payload once all dealer-fitted extras are included?
- Are there any known faults, leaks, or issues with the heating system?
- Is the caravan registered with CRiS, and is there outstanding finance?
- What tow car did you use, and did you encounter any towing issues?
- Are the gas and electrical certificates current?
- How old are the tyres (check the date code yourself)?

Weight checks: MTPLM, MIRO and payload
The VIN plate inside the caravan shows the key weight figures. Three numbers matter most before you buy.
- MTPLM: the maximum laden weight you are legally allowed to tow. Compare against your car's braked towing limit and the 85% rule.
- MIRO: the empty mass as the caravan left the factory. Real-world MIRO is often higher once dealer extras are fitted.
- Payload: MTPLM minus MIRO. This is everything you can pack: water, gas, awning, bedding, food and accessories. Aim for 150kg or more.
- Noseweight: the downward force on your tow ball. Use the lower of the caravan's noseweight limit and your car's noseweight limit.
Use the caravan payload calculator to sense-check whether a used caravan has enough payload for your real packing list.
CRiS registration, ownership and stolen-caravan checks
Most UK touring caravans built since 1992 carry a unique 17-digit CRiS (Central Registration and Identification Scheme) number, etched on the windows and stamped on the chassis. Always confirm the seller is the registered keeper before paying a deposit.
- Match the CRiS number on the document to the etched window numbers and the chassis plate.
- Run a CRiS check (or equivalent paid HPI-style check) to look for outstanding finance, theft markers or insurance write-offs.
- Ask to see proof of address and photo ID for the registered keeper, especially for private sales.
- If the seller cannot produce the CRiS document, treat that as a serious red flag and walk away.
This guidance is general information, not a legal opinion. For high-value purchases, consider a professional pre-purchase inspection and a formal HPI-style check.
Common red flags
- No CRiS document, or the seller refuses to show ID.
- Missing or patchy habitation check history, especially recent years.
- Strong air freshener smells masking damp or mildew.
- Soft floor, springy walls, or staining around windows and roof lights.
- Tyres older than 5 years (check the date code) regardless of tread.
- Pressure to pay a deposit before viewing or before checks are complete.
- Price well below market value for the model and year.
- Recent repaint, fresh sealant or new panels with no paperwork.
What to do if you find a problem
Finding an issue at a viewing is not always a deal-breaker. Use it as information.
- Pause the sale. Do not pay a deposit while questions are open.
- Ask for the issue in writing, including any quotes for repair from a workshop.
- Get an independent professional inspection from an NCC Approved Workshop where damp, structural, gas or electrical issues are suspected.
- Renegotiate based on a written repair quote, or walk away if the seller will not engage.
- If you have already paid and bought from a dealer, raise the issue in writing and reference your Consumer Rights Act 2015 protections.
- For private sales, your protection is limited. This is why a pre-purchase inspection is usually worth the cost.
Frequently Asked Questions
Damp. Water ingress is the single biggest killer of caravan value and structural integrity. Always get a professional damp check or use a damp meter yourself. Look for soft spots around windows, roof edges, floor corners, and the front and rear panels. Damp damage is expensive to repair and can make a caravan worthless.
Dealer purchases offer more protection: you get Consumer Rights Act coverage (up to 6 years), the dealer has a reputation to protect, and many offer warranties. Private sales are often cheaper but offer no legal protection beyond "as described". If buying privately, budget for an independent inspection.
Aim for at least 150kg of payload (MTPLM minus MiRO). This covers water (around 20kg for a basic fill), gas (10-15kg), bedding, clothes, food, and an awning. Many used caravans have 100-150kg of payload. Which sounds adequate but fills up quickly once you add dealer-fitted extras like a motor mover or solar panel.
There is no universally "best" year, but be aware that post-2012 caravans are measured to the MiRO standard (more accurate weights), and post-2017 models generally have better build standards from NCC certification. Older caravans can be excellent value if they have a clean damp history and documented service records.
Use an HPI check or similar finance check service. This confirms whether the caravan has outstanding finance, has been reported stolen, or has been written off by an insurer. The CRiS (Central Registration and Identification Scheme) database is the caravan-specific equivalent.
You should receive: the CRiS registration document, service history (habitation check records and damp reports), gas and electrical safety certificates, the owner's handbook, and any warranty documentation. Missing paperwork is a red flag.
