    Marine surveyors

    Marine surveyors for narrowboats & canal boats

    A survey checks a boat's condition, hull thickness and systems — you'll typically want one when buying a boat, or to insure or renew cover on an older one. Around 100 surveyors cover the UK inland waterways. Works alongside the official Boat Safety Scheme.

    A survey is not the same as a BSS examination. A Boat Safety Scheme certificate confirms your boat meets safety requirements; a survey assesses its overall condition and value. Many boats need both — and many surveyors carry out BSS examinations too.

    Types of survey

    Pre-purchase survey

    The full check before you buy — hull thickness readings, structure, systems, engine, and often oil/fuel sampling. The one most buyers and lenders rely on.

    Insurance / condition survey

    A condition-and-valuation report accepted by insurers. Many insurers require one for older boats before offering or renewing cover.

    Valuation report

    An independent market-value assessment for finance, sale, insurance or probate.

    Hull / out-of-water survey

    The boat is lifted so the surveyor can gauge steel thickness and inspect the baseplate and below-waterline hull.

    Boat Safety Hub lists these resources to help you find a qualified surveyor. We are not a surveyor and do not carry out surveys. A verified surveyor directory is coming soon.

    Many BSS examiners also carry out surveys

    If you need both a survey and a Boat Safety Scheme certificate, a single examiner-surveyor can often do both. Browse verified BSS examiners near you.
