Depth Limits for Scuba Diving

Why depth limits matter for your policy

Insurance providers categorise scuba diving as a high-risk activity, meaning standard policies often restrict how deep you can go. These limits are not arbitrary; they are designed to align with recognised training standards and the increased physical risks associated with deeper dives, such as decompression sickness. If you dive to 25 metres on a policy that only permits 18 metres, your insurer may refuse to pay for expensive hyperbaric oxygen therapy or emergency medical evacuation. It is vital to check the 'Activity Pack' or 'Sports and Activities' section of your policy document before you enter the water.

• Standard policies often cap depth at 12 or 18 metres.
• Extensions are required for depths between 30 and 40 metres.
• Commercial or technical diving usually requires specialist specialist cover.
• Breaching depth limits can invalidate your entire medical claim.
• Insurers expect you to follow the rules of your governing body (e.g., PADI or BSAC).

What is typically covered underwater

When you have the correct depth limits for scuba diving in place, your insurance provides a safety net for several serious scenarios. Most UK policies cover emergency medical expenses, including hospital stays and specialist treatments required following a dive accident. Crucially, this often includes the cost of a decompression chamber, which can be prohibitively expensive in popular dive destinations like Egypt or the Maldives. You are also typically covered for repatriation back to the UK if your injury prevents you from using your original return flight.

Common exclusions and depth restrictions

Even with an activity extension, certain conditions must be met to remain covered. Most insurers will only cover you if you are diving with a qualified instructor or if you hold a recognised diving qualification yourself. Solo diving is almost universally excluded from standard and even many specialist travel insurance policies. Additionally, diving while under the influence of alcohol or against medical advice will result in a rejected claim, regardless of the depth reached.

• Diving beyond the maximum depth specified in your policy schedule.
• Diving without a buddy or professional supervision.
• Diving against FCDO advice or local maritime regulations.
• Claims resulting from pre-existing medical conditions not declared.
• Loss or damage to hired diving equipment (check your 'Baggage' section).

Typical costs and pricing factors

Adding scuba cover to a standard UK travel insurance policy for 2026 generally adds a modest premium for shallow depths, but costs rise as the depth limit increases. For a one-week trip to Europe, a basic 18m extension might cost an extra £10 to £20, whereas a 40m extension for a worldwide trip could add £40 or more to the total. Pricing is influenced by your destination, your age, and whether you are opting for a single trip or an annual multi-trip policy. Insurers also look at the local availability of medical facilities when calculating premiums for high-risk activities.

Choosing cover for specific destinations

Your destination plays a significant role in how you should select your depth limits. In the EU, while your GHIC (Global Health Insurance Card) provides access to state healthcare, it rarely covers private search and rescue or specialized dive medicine. For destinations like the Red Sea or the Caribbean, the cost of medical evacuation can be astronomical, making high-limit medical cover essential. Always ensure your policy meets the specific requirements of the country you are visiting, as some local operators may ask for proof of insurance before allowing you on a boat.

Evidence required for insurance claims

If you need to make a claim related to a diving accident, the loss adjuster will require specific documentation to prove you were operating within your policy limits. This often includes your dive computer logs, which show the maximum depth reached and the duration of the dive. You will also need to provide your certification card (C-Card) to prove you were qualified for the dive attempted. Lack of evidence can lead to lengthy delays or the rejection of your claim by the Financial Ombudsman Service if a dispute arises.

• A copy of your PADI, BSAC, or NAUI certification.
• Logbook or dive computer data showing the depth and time.
• Medical reports from the treating physician or chamber operator.
• Receipts for any out-of-pocket medical or transport expenses.
• Police or coastguard reports if an emergency rescue was involved.

UK regulatory context and the FCDO

The Financial Conduct Authority (FCA) ensures that UK insurers provide clear information about policy exclusions, including depth limits. Furthermore, the Foreign, Commonwealth & Development Office (FCDO) provides safety advice for British travellers engaging in water sports abroad. It is a standard requirement of UK insurance that you do not travel to a region where the FCDO advises against 'all travel' or 'all but essential travel'. If you ignore these warnings, your scuba diving cover will likely be voided entirely, regardless of your depth or experience level.

Practical checklist for your dive trip

Before heading to the airport, perform a final check of your insurance documentation. Ensure that the 'Activity Pack' listed on your certificate matches your planned diving activities. It is often helpful to print a copy of your policy's emergency contact number and keep it in your dive bag. If you are trying a 'Discover Scuba' session for the first time, verify that your policy covers uncertified divers under professional instruction, as some cheaper policies may exclude this.
