What insurers say their customers pay
| Insurer | Average premium | Based on |
|---|---|---|
| Craftinsure | £291 a year | Customer average, including up to £5m public liability, excluding add-ons |
| GJW Direct | £326 a year | 1,107 narrowboat, barge and houseboat policies, July 2026 |
An average hides a wide spread. A cheaper boat on a leisure mooring will usually pay less, and an expensive boat that someone lives on will usually pay more. We aren’t paid by either insurer. They’re here because they publish real figures, which most don’t.
Cost by level of cover
| Cover | Typical cost a year |
|---|---|
| Third party only | £80–£150 |
| Third party, fire and theft | £150–£300 |
| Comprehensive, leisure use | £250–£600 |
| Comprehensive, liveaboard (57ft boat) | £400–£650 |
The cover levels come from an independent 2026 guide by The Boat Floats, and they line up with the insurer averages above. Our running costs calculator uses £250 to £600 for comprehensive cover and adds 10 to 20% for living aboard.
What the Canal & River Trust requires
You need at least £2,000,000 of third-party liability cover before the Canal & River Trust will sell you a licence. That covers claims against you if your boat injures someone or damages their property. It’s the only cover CRT insists on. Insuring the boat itself is your choice, but if the boat is your home or most of your savings, it’s hard to justify going without.
Most specialist policies include more than the minimum. Craftinsure and GJW Direct both include £5m of liability cover as standard.
What moves the price
- The boat’s value matters most. Comprehensive cover is priced on the agreed value, so set it at what the boat would really sell for, not what you hope it’s worth.
- Living aboard usually adds 10 to 20%, and you must declare it. Some insurers also ask whether you continuously cruise.
- Where you cruise. Tidal and coastal waters cost more to insure than inland canals. Tell your insurer if you plan to go on them.
- Age and condition. Older boats need a recent survey, and a poor one can mean higher premiums or conditions on the policy.
- Your record. Years of no claims and boating experience bring the price down. GJW Direct lets you keep your no claims bonus after one claim in a policy year, but two or more claims lose it.
- The excess. A higher excess lowers the premium. Only pick one you could pay tomorrow without stress.
Surveys for older boats
Insurers want to know the hull is sound, so they ask for a survey once a boat reaches a certain age. Craftinsure asks for a survey report no more than five years old on boats over 30. GJW Direct asks for a full out-of-water survey with ultrasonic hull readings on boats aged 30 or more, plus a valuation survey from the last ten years, and won’t accept a hull-only report. Some insurers ask from 15 or 20 years. If you’re buying, get the pre-purchase survey done to a standard your insurer accepts so you only pay for one. Surveys and the rest of the purchase costs are covered in the real cost of buying a narrowboat.
Check the salvage cover
The Canal & River Trust warns that not every policy covers salvage after a sinking or a fire, and that recovering a boat can cost thousands of pounds. Before you buy, look for the salvage and wreck removal limit on the quote. If you can’t find it, ask.
How to pay less without being underinsured
- Get at least three quotes, including one from a specialist boat insurer or broker.
- Set the agreed value at a realistic sale price.
- Tell the insurer about security, such as a locked mooring.
- Choose the highest excess you could actually pay.
- Don’t drop salvage, liability or liveaboard cover to save a few pounds. Those are the claims that would cost the most.
Insurance in the bigger budget
Insurance is usually one of the smaller lines in a boat budget. The licence, mooring, heating and maintenance all cost more. For a 57ft boat, the licence alone is £1,404.46 a year with a home mooring.

Frequently asked questions
- How much is narrowboat insurance a year?
- Most owners pay £250 to £600 a year for comprehensive cover in 2026. Two specialist insurers publish their customer averages: £291 a year at Craftinsure and £326 a year at GJW Direct. Third-party-only cover is cheaper, typically £80 to £150. Living aboard usually adds 10 to 20%.
- Do you legally need insurance for a narrowboat?
- You need at least £2 million of third-party liability cover before the Canal & River Trust will issue a licence, so in practice every boat on CRT waters needs it. Cover for damage to your own boat is optional, but most owners of a boat worth more than a few thousand pounds take it.
- Does living aboard affect narrowboat insurance?
- Yes. You must tell your insurer if the boat is your home. Liveaboard cover typically costs 10 to 20% more than leisure use, and some insurers also ask whether you continuously cruise. If you live aboard on an undeclared leisure policy, a claim may not be paid.
- Do older narrowboats need a survey for insurance?
- Usually from about 30 years old. Craftinsure asks for a survey report no more than five years old on boats over 30, and GJW Direct asks for a full out-of-water survey with ultrasonic hull readings on boats aged 30 or more. Some insurers ask earlier. A survey typically costs £600 to £1,200 including the lift-out.
- Does narrowboat insurance cover salvage after a sinking?
- Not always. The Canal & River Trust warns that not every policy covers salvage after a sinking or fire, and that recovery can cost thousands of pounds. Check the salvage and wreck removal limit on any quote before you buy.
