DSEAR assessment cost: what the fee is actually built from
Updated
DSEAR assessment quotes vary more than almost any other compliance purchase, because the same phrase can describe a half-day review or a multi-week hazardous area classification exercise. Here is what to pin down before comparing.
Why the price varies so much
Two proposals headed DSEAR risk assessment can describe genuinely different work. One may be a review of your existing arrangements against the regulations. Another may include a full hazardous area classification: identifying every release source, calculating the extent of hazardous areas and issuing drawings. That difference, not regional pricing, is what moves a DSEAR quote.
The factors an assessor is pricing
- Substances. How many, and which types. Flammable liquids, flammable gases and combustible dusts each bring their own scenarios and their own zone series.
- Site size and complexity. The assessment covers every place an explosive atmosphere may occur, including connected spaces, so plant items and process steps drive time on site.
- Existing drawings. Updating current hazardous area classification drawings is far cheaper than producing them from nothing.
- Number of zones. Zones cascade into equipment selection, signage at points of entry and the verification of explosion safety.
- Deliverable depth. Findings only, or findings plus action plan, equipment schedule and basis of safety.
- Competence of the assessor. Hazardous area classification is a specialist discipline; a cheaper generalist report that an insurer rejects is not a saving.
- Review cycle. Regulation 5(3) requires the assessment to be kept up to date, so budget for reviews, not just for the first report.
Making two proposals comparable
- Give every assessor the same scope: substances held, areas in scope, whether drawings exist, and what triggered the work.
- Ask each to price hazardous area classification drawings as a separate line. It is the item that most often explains a gap between two quotes.
- Ask how many days on site are assumed and what happens if the survey runs longer.
- Ask for a contents page or a sample report. The difference between a findings report and a working document is visible in one glance.
If an assessor quotes without asking what substances you hold or whether drawings exist, they are guessing at the scope. That is the quote most likely to change after the site visit.
What the regulations fix, and what they do not
DSEAR fixes the duty, not the fee. Regulation 5 requires a suitable and sufficient risk assessment where a dangerous substance is or is liable to be present, and regulation 7 requires places where explosive atmospheres may occur to be classified into zones under Schedule 2, with equipment requirements under Schedule 3 and signs at points of entry under Schedule 4 (legislation.gov.uk). Nothing in the regulations sets or caps what a consultant may charge.
