How to become a marine surveyor in the UK (2026 guide)

A step-by-step route to becoming a working marine surveyor in the UK — training, accreditation, insurance, first clients, and realistic earnings.

Marine surveying is one of the few maritime careers you can enter mid-life, run as a solo business, and grow without ever needing to join a firm. Here's the practical route into it in the UK in 2026 — what to train in, what to spend, and how to land your first paid surveys.

Step 1: Decide what you'll survey

"Marine surveyor" covers commercial cargo work, superyachts, small craft and specialised niches like rig surveying. For most people starting out, the realistic target is small craft and yacht surveying — pre-purchase, insurance and condition surveys on vessels under 24m. The training is shorter, the insurance is cheaper, and the client pool is enormous.

Step 2: Get qualified

The default route is the IIMS Professional Qualification in Yacht and Small Craft Surveying — distance learning with module exams and a final submission. Budget 18–36 months part-time and £4,500–£6,000 in fees. See our deep dive on IIMS, YDSA and SAMS for how the accreditations compare.

Step 3: Get insured

You can't trade without professional indemnity insurance. Expect:

  • PI cover: £400–£900/year for a solo surveyor doing under £100k revenue
  • Public liability: £150–£300/year
  • Tools and equipment cover: optional but cheap

Disclose your qualification status honestly — underwriters quote sharper rates for IIMS-qualified surveyors.

Step 4: Kit yourself out

The starter kit for a small craft surveyor:

  • Moisture meter (Tramex Skipper or similar) — £400–£600
  • Hammer and mallet for hull tapping — £40
  • Mirror and torch set — £60
  • Borescope (USB or wifi) — £80–£200
  • Digital callipers — £30
  • Smartphone with a good camera (your most-used tool)
  • Tablet or phone running mobile survey software for capture

Total: roughly £700–£1,000 to start.

Step 5: Set up the business

Register as a sole trader with HMRC (free, takes 10 minutes online) or form a limited company if you expect to bill over £40k in year one. Open a business bank account, get a simple accounting tool, and write down your hourly cost-of-living target — this becomes your minimum survey fee.

Step 6: Land your first surveys

The hardest part. Three channels that work:

1. Brokers — visit every brokerage within 50 miles, in person, with a one-page rate card. Brokers refer surveyors all day; being top of mind matters more than being best. 2. Marina noticeboards — old-school but still effective. A neat A5 card with your qualification and contact details gets calls. 3. Insurer panels — apply to be on the approved-surveyor lists for Pantaenius, GJW, Haven Knox and similar. Slow to get on, lucrative once there.

Step 7: Deliver fast

The single biggest reason new surveyors fail is slow report turnaround. Buyers are mid-negotiation and need findings fast. If you can deliver a branded PDF in 24–48 hours, you'll out-compete established surveyors who take a week.

This is where modern survey software like evalo earns its keep — mobile-first capture on the boat, AI-assisted writing at the desk, branded PDF in a click. It's the difference between a five-day report cycle and a one-day one.

Realistic earnings

A working small craft surveyor doing 3–4 surveys a week at £700–£1,000 each grosses £110,000–£170,000 annually. After insurance, software, travel and tax, take-home is typically £55,000–£90,000 in year two onwards. Year one is usually half that as you build the pipeline.
