Traditional Contractor Pricing

Professional water hygiene contractors typically charge £250–£400+ for a site visit, which includes:

  • Engineer travel time

What Affects Legionella Testing Cost?

1. Number of Samples

More samples = higher cost. Typical requirements:

  • Small house or flat: 2 samples
  • Small office or retail unit: 2–4 samples
  • Care home or healthcare setting: 8–20+ samples
  • Hotel, leisure or large commercial site: 8–20+ samples

Learn how many samples you need.

2. Laboratory Fees

UKAS-accredited laboratory analysis ensures reliable, legally defensible results. Unaccredited labs may be cheaper but results may not be accepted for compliance purposes.

3. Engineer Visits (Traditional Contractors)

Professional sampling includes engineer travel time, on-site collection, and reporting. This is the largest cost component for traditional contractor services.

4. Travel and Location

Remote locations or sites requiring long travel times increase contractor costs. Self-sampling eliminates this expense entirely.

5. Reporting and Certification

All testing should include a certified laboratory report. UKAS accreditation ensures results meet UK regulatory standards.

Example Pricing Comparison

Property Type Samples Needed Traditional Contractor Self-Sampling Kit
Small rental property 2 samples £350–£500 From £79.90 plus VAT
Small office 4 samples £450–£600 From £159.80 plus VAT
Care home 10 samples £600–£800+ From £399.50 plus VAT

Prices are indicative and may vary based on location, complexity, and service provider.

Why Cheaper Isn't Always Better

Unreliable testing can be costly in the long run:

  • Unaccredited laboratories may provide inaccurate results that aren't accepted for compliance
  • Poor sampling technique can contaminate samples or miss contamination
  • Inadequate reporting may not meet regulatory requirements

Always choose UKAS-accredited laboratory testing to ensure results are reliable and legally defensible.
