Public liability insurance premiums scale mainly with turnover and coverage limit. Low-risk trades (office-based consulting) price around 0.3-0.5% of turnover for 2m cover. Medium-risk (trades, beauty) closer to 1%. High-risk (construction, events) 1.5-3%. The exact premium depends on claims history and insurer appetite, but the model here gives a reasonable starting point.

Quick example

With annual turnover of 100,000 and coverage limit of 2,000,000 (plus risk factor of 1), the result is 500.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Annual Turnover, Coverage Limit, and Risk Factor (0.5 low, 1 medium, 2 high). Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Base rate 0.5% of turnover for 2m cover at medium risk, scaled linearly by coverage limit and risk factor. Working estimator only — real quotes vary by insurer and claims history. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Using this as a check-in

Re-run this every three months. A single reading tells you where you stand; four readings tell you whether things are improving. The trend matters more than any individual snapshot.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

Public liability premium produces an estimate based on the inputs provided.

Inputs

Annual Turnover:100,000 £
Coverage Limit:2,000,000 £
Risk Factor (0.5 low, 1 medium, 2 high):1
Expected Result£500.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Frequently Asked Questions

Is this a real quote?
No — it is a modelling estimator. Actual premiums depend on claims history, insurer appetite, policy wording, and excess level. Always get multiple broker quotes.
Who needs public liability?
Any business interacting with the public or working on client sites. Many clients will not contract without seeing a certificate.
How much cover do I need?
1m is common baseline. 2m is common for consultancy. 5-10m often required on construction sites. Client contracts usually specify.
What about excess?
Higher excess lowers the premium. Zero-excess policies cost more. Balance premium savings against the out-of-pocket risk on a claim.
