Caravan storage explained, what CaSSOA actually tells you

Quick Takeaways:

• CaSSOA Ratings: Platinum, Gold, Silver, and Bronze levels indicate security intensity; higher ratings often trigger insurance discounts of up to 25%.
• The 30-Minute Rule: Proximity is key for maintenance and spontaneity. Aim for a site within 30-45 minutes of home.
• Surface & Drainage: Prioritise hardstanding over grass to prevent chassis corrosion, mould, and tyre flat-spots during UK winters.
• Insurance Compliance: Never assume a site is covered; verify the specific postcode and CaSSOA level with your insurer before signing.
• 2026 Trends: Look for sites offering solar-friendly bays or trickle-charge EHU to maintain modern lithium battery systems.

Storage is rarely the most exciting part of caravan ownership, but it is arguably the most critical for long-term enjoyment. If your storage site is distant, awkward to access, or feels insecure, those spontaneous weekend getaways in your Bailey Alicanto or Swift Challenger will quickly disappear. Furthermore, poor storage environments can lead to damp issues and accelerated depreciation.

Who this guide is for

Whether you are a first-time buyer browsing used caravans for sale or a seasoned tourer looking to upgrade your security, this guide provides a realistic framework for choosing storage and understanding what CaSSOA accreditation actually means for your peace of mind and your wallet.

What is CaSSOA?

The Caravan Storage Site Owners’ Association (CaSSOA) is the UK’s leading industry body for caravan and motorhome storage standards. Founded in 1999, it was established to combat caravan theft by creating a national network of secure sites through rigorous physical inspections and risk assessments.

Understanding the 2026 Accreditation Levels

CaSSOA sites are surveyed by independent experts every five years (or upon significant site changes) and awarded a status based on their security features, including perimeter fencing, CCTV, alarms, and gated access:

• Platinum: The highest level, introduced to reflect modern tech. Expect 24/7 monitored CCTV, sophisticated access control, and often individual bay security.
• Gold: High security with a proven track record of safety measures and comprehensive perimeter protection.
• Silver: Standard security measures that exceed basic requirements, providing a solid middle ground for cost and safety.
• Bronze: Entry-level accreditation ensuring basic security protocols, such as perimeter fencing and gated entry, are in place.

Pro Tip: Many specialist insurers offer significant premium discounts if you store your caravan at a Gold or Platinum CaSSOA site. Check our guide on insurance exclusions to ensure your policy stays valid, as some insurers mandate CaSSOA-rated sites for high-value models like the Bailey Pegasus Grande GT75 Bologna.

The "Reality Check": Factors Beyond Security

While security is paramount, practical usability determines how much you will actually use your caravan.

1. The Distance Factor

Distance matters more than most owners admit. If storage adds 90 minutes of traffic-heavy driving to every trip, you will travel less. Aim for a site within 30-45 minutes of your home. This also makes it easier to pop over for "winter checks" or to prep the van the night before a big trip.

2. Access Hours & Flexibility

Does the site allow 24-hour access? Some sites have strict "curfews" (e.g., no entry after 8 PM). If you get stuck in Friday night traffic on the M5, you don't want to find yourself locked out of the compound with nowhere to park. Also, check if they require 24-hour notice before you can collect your van.

3. Ground Surface & Drainage

In the UK climate, hardstanding (concrete, tarmac, or compacted gravel) is vastly superior to grass. Grass retains moisture, which can lead to chassis corrosion and mould growth. It also becomes a bog in winter, making it difficult to manoeuvre heavy models, especially those with a twin-axle layout which are prone to "scrubbing" on soft ground. If you are unsure of your van's weight when fully laden for storage, use our Caravan Towing Calculator to stay within safe limits.

2026 Outlook: The Rise of "Smart" Storage

As we move into 2026, more sites are adopting app-based access and individual bay monitoring. When choosing a site, ask if they have plans for electric hook-up (EHU) points in storage bays—increasingly popular for keeping leisure batteries topped up during the off-season. Additionally, check if the site's layout allows for solar panels to remain effective (i.e., not shaded by high walls or trees).

Frequently Asked Questions

Does CaSSOA cover my caravan against theft?

No. CaSSOA is an accreditation body for the site. You still need your own comprehensive insurance policy. CaSSOA simply reduces the risk, which insurers reward with lower premiums.

Can I store my motorhome at a CaSSOA site?

Yes, most CaSSOA sites accept motorhomes and campervans, such as a Volkswagen California or Bürstner Habiton, though you should check if they have specific bays for wider or longer vehicles. Use our Motorhome Weight Checker to ensure the site's surface can support your vehicle's MTPLM.

What is the difference between Gold and Platinum?

Platinum was introduced to recognise sites using advanced technology like ANPR (Automatic Number Plate Recognition) and enhanced CCTV analytics that go beyond the physical barriers required for Gold status.
