How Much Does a Narrowboat Survey Cost?

A survey is the single best way to avoid an expensive mistake when buying a boat — but "how much will it cost?" is one of the first questions every buyer asks. Here's a plain-English guide to what a narrowboat or canal boat survey costs, what drives the price, and what you actually get for it.

The short answer

For a full pre-purchase (out-of-water) survey on a narrowboat, expect to budget roughly £15–£20 per foot of boat length — so around £400–£800+ for a typical 40–60ft boat. On top of that you'll usually pay the marina or boatyard separately for lifting the boat out (the crane-out or dry-dock fee). Lighter surveys — an insurance/condition survey or a valuation — generally cost less.

Prices vary by surveyor, region and how much work is involved, so always get a written quote.

What drives the cost

• Boat length. Most surveyors price per foot, so a 57ft boat costs more to survey than a 40ft one.
• Type of survey. A full pre-purchase hull-and-systems survey is the most thorough (and priciest); an insurance/condition survey or a valuation is lighter.
• In or out of the water. A proper hull survey needs the boat lifted so the surveyor can take ultrasonic steel-thickness readings — that's the most reliable check, but it adds the lift-out cost.
• Region and travel. Rates differ around the country, and some surveyors charge travel for distant boats.
• Extras. Oil/fuel sampling, engine testing or a written valuation can add to the fee.

What you usually pay for separately: the lift-out

The surveyor's fee is only part of the cost. To survey the hull properly, the boat has to come out of the water — a crane-out or dry-dock booked with the marina or boatyard. That's billed separately (often £100–£250+ depending on the yard), and you'll want to line it up so the surveyor can attend on the day. Browse UK marinas and boatyards that offer lifting and hard-standing.

The main types of survey — and roughly what they cost

• Pre-purchase survey — the full check (hull thickness, structure, systems, engine). The one most buyers and lenders rely on. Highest cost.
• Insurance / condition survey — a condition-and-valuation report accepted by insurers; often a little less than a full pre-purchase survey.
• Valuation report — an independent market value for finance, sale or probate. The lightest and cheapest option.
• Hull / out-of-water survey — focused steel-thickness readings and baseplate inspection.

For more on what each involves, see our marine surveys guide.

Is a survey worth the money?

Almost always, yes. A steel narrowboat can hide serious, expensive problems — hull pitting and overplating, a tired engine, dodgy gas or electrics. A £500–£800 survey that finds a £5,000 problem (or gives you the evidence to renegotiate the price) pays for itself many times over. Lenders and many insurers will also expect one.

How to book — and what comes next

1. Find an accredited surveyor (IIMS or YDSA/YBDSA) who regularly surveys inland-waterways craft — see our surveyors guide. Many BSS examiners also carry out surveys, so you can sometimes get both done together.
2. Book the lift-out with the marina or boatyard for the same day.
3. Read the report and use it — to walk away, to renegotiate, or to plan repairs.

Frequently asked questions

Is a survey the same as a BSS examination? No. A BSS examination checks that your boat's safety systems meet the required standard; a survey assesses its overall condition and value. Many boats need both, and many examiners do both.

Do I need the boat out of the water? For a full hull survey, yes — that's the only way to take accurate steel-thickness readings. A lighter in-water survey is possible but less thorough.

Who pays for the survey when buying? The buyer normally pays for the survey and the lift-out. It's your due diligence on the purchase.

How long does a survey take? A full pre-purchase survey typically takes a few hours on the day, with the written report following shortly after.
