How is employers' liability insurance cost calculated in the UK?

UK underwriters multiply a base rate by headcount, turnover band, trade risk loading, and claims history. This calculator exposes each multiplier and cites the broker-survey data behind it.

Is this calculator a real quote?

No. It produces an indicative range based on Q1 2026 broker-submission data. To bind cover you need an FCA-authorised intermediary. InsuranceDico is not FCA-authorised and cannot place cover.

Why do estimates vary so widely?

The low-to-high spread (typically 2.1×) reflects underwriter appetite differences across the UK market. Two insurers can quote the same risk at very different prices on the same day.

Where do the multipliers come from?

From the InsuranceDico Q1 2026 broker submission survey (n = 8 UK underwriters), BIBA member-firm data, and ABI commercial-lines rating notes. Full sources are on the methodology page.

How we calculate employers' liability insurance cost

Every estimate on this page is built from a base rate of £95 multiplied by four factors: headcount, turnover band, trade risk loading, and claims history. The high estimate is the low estimate multiplied by a 2.10× broker market spread. Multipliers are sourced from our Q1 2026 broker submission survey (n = 8 UK underwriters), BIBA member-firm data, ABI commercial-lines rating notes, and FCA value-measures filings.

We publish the formula so any broker or accountant can audit our numbers. If a UK underwriter's number diverges from this range by more than 25%, ask them to itemise which factors they weight differently.
