Quick answer: how much is public liability insurance in the UK?
Public liability insurance can cost anywhere from £60–£180+ per year for some low-risk businesses, to £200–£600+ for higher-risk trades — and more for complex, higher exposure work. The spread is big because insurers price based on: your trade, turnover, work environment (domestic vs commercial), and the cover limit you choose.
These ranges are for general guidance only. Your actual premium depends on insurer criteria, declared activities, turnover, claims history and policy wording. To get an accurate price for your setup, compare quotes here.
£2m, £5m and £10m are the most common public liability limits in the UK — and your contracts often decide which you need.

Typical public liability cost bands (UK)
The table below gives realistic “orientation” cost bands. Think of these as sanity checks when comparing quotes. If a quote is outside these ranges, it doesn’t automatically mean it’s wrong — but it does mean you should double-check your details, cover limit and wording.
| Business setup | Work environment | Typical PL limit | Indicative annual cost | Why it lands there |
|---|---|---|---|---|
| Low-risk services | Mostly remote / low public exposure | £1m–£2m | £60–£180+ | Lower chance of expensive property damage or injury claims. |
| General services / light trades | Domestic properties | £2m–£5m | £90–£320+ | Customer premises work increases exposure to claims. |
| Trades with higher exposure | Domestic + occasional commercial | £5m | £180–£600+ | Tools, materials, and higher-value damage scenarios. |
| Higher-risk / specialist work | Commercial sites / public areas | £5m–£10m | Varies widely | Higher hazard, stricter contracts, broader third-party exposure. |
Next, let’s break down costs by trade — because this is usually the biggest pricing driver.
Costs by trade: plumbers, builders, roofers & more
Insurers look at the kinds of claims each trade is likely to generate. A plumber’s risk often involves water damage in occupied homes, while a roofer’s risk often involves working at height and potential falling objects. Those claim patterns influence premiums.
| Trade | Typical PL limit | Indicative annual cost | Common exposure |
|---|---|---|---|
| Plumbers | £2m–£5m | £120–£450+ | Water damage, leaks, damage to kitchens/bathrooms. |
| Builders | £5m | £180–£600+ | Materials, sites, wider third-party interaction. |
| Roofers | £5m–£10m | £250–£850+ | Working at height, falling objects, weather exposure. |
| Cleaners | £1m–£2m | £60–£220+ | Slip/trip risks, chemicals, accidental damage. |
| Decorators | £1m–£2m | £70–£260+ | Damage to surfaces/furnishings, ladders. |
| Carpenters / joiners | £2m–£5m | £110–£420+ | Tools, dust, occupied properties and sites. |
| Landscapers / gardeners | £1m–£2m | £80–£320+ | Public exposure, debris, machinery use. |
| Flooring contractors | £2m–£5m | £110–£420+ | Property damage, adhesives/materials. |
| Heating engineers | £2m–£5m | £140–£520+ | Heat environments, customer properties, tools. |
| Electricians | £2m–£5m | £120–£450+ | Occupied properties, tools, third-party damage scenarios. |

“Plumber” can mean domestic repairs, full bathroom installs, commercial work, or subcontract site work. Your activity mix changes exposure — and pricing. Being precise helps insurers price you correctly and reduces cover mismatches.
£2m vs £5m vs £10m: does the limit change the price?
Yes — but not always as dramatically as people expect. Increasing the limit increases the maximum payout the insurer might have to make. However, for many trades, the uplift from £5m to £10m can be relatively modest compared to the uplift from £1m to £5m.
Common for domestic-only work, lighter services, and smaller contracts. Often a “starter” limit for sole traders.
Very common for trades. Often requested by landlords, property managers and commercial clients.
Common for commercial sites, onboarding packs and higher exposure work. Helps reduce paperwork friction.
Price multiple limits with identical details and select the limit required by contracts and exposure.
If a client requires £5m or £10m, choose that limit — otherwise you may not be allowed to start work. You can compare multiple limits quickly here: Start a quote.
What affects premiums (the real pricing levers)
If you want to understand why quotes differ, focus on the levers below. Two businesses in the same trade can get very different pricing because their activities, environment, and claims profile are different.
1) Your activities (not just your trade name)
Insurers price based on what you actually do. Working at height, using heat, doing structural work, working in public spaces, or working on busy commercial sites can all affect price. Accuracy matters.
2) Turnover
Turnover is a proxy for exposure. More turnover usually means more jobs, more customer interactions and more chance of an incident. Use a realistic estimate — huge underestimates can cause issues later.
3) Where you work (domestic vs commercial vs public)
Working in private homes can be different from commercial sites or communal buildings. Exposure changes with footfall, site rules, high-value property, and the number of third parties around you.
4) Claims history
Previous claims can increase premiums or reduce insurer appetite. Even if a claim was minor, it can influence underwriting.
5) Wording and exclusions
Not all policies are equal. Two quotes might look similar, but one policy may exclude certain higher-risk activities you actually do. Cost matters — but so does relevance.
Give a clear description of your activities. Clarity often improves underwriting outcomes and reduces “padding” in quotes.
Understating your activities for cheaper pricing. Misdeclared activities can create cover issues if a claim occurs.
Claims examples that explain why PL costs what it costs
Public liability premiums reflect the kinds of claims insurers expect in your industry. Here are realistic examples that show why some trades cost more:
Example 1: water damage from a leak (plumber)
A small fitting fails after a repair, causing water damage to a ceiling and electrics. The claim can include repairs, redecoration, and accommodation costs. This “cascade effect” is why plumber premiums can be higher than people expect. See: PL for plumbers.
Example 2: injury from a trip hazard (any trade)
A customer trips over your equipment or trailing leads. Injury claims can include medical costs and loss of earnings. Even when the incident seems “minor”, legal handling can be expensive — which is why defence costs matter.
Example 3: property damage during renovation (builder)
Accidental damage to existing structures, expensive finishes, or neighbouring property can become costly quickly — especially in high-value homes. See: PL for builders.
Example 4: falling object / working at height (roofer)
A tool or tile falls and damages property or injures someone. This is a classic “severity” risk, which is why roofers often face higher premiums. See: PL for roofers.
Understanding claim patterns helps you choose the right limit and wording — and helps you explain your work clearly when requesting quotes.
Sole traders: typical pricing + what you actually need
Sole traders are the biggest group searching for public liability cost. You’re usually pricing based on your activities, turnover, and where you work. Many sole traders also buy PL because clients ask for proof of cover before a job starts.
If you’re self-employed or a one-person business, use this dedicated guide: Public Liability Insurance for Sole Traders.
Domestic-only + £2m cover might be enough for some. Subcontract work, commercial sites or higher-risk activities often push you towards £5m or £10m.
Proof of cover: certificates & why clients ask for them
Many clients ask for a certificate before allowing work to start — especially commercial sites, landlords, and property managers. Keep a digital certificate stored on your phone so you can send it quickly.
- Commercial sites: onboarding packs and inductions.
- Property managers: proof for landlord/agent work.
- Events/venues: markets and public venues often require documentation.
Bundling with EL / PI / product liability
Bundles can be cost-effective and reduce paperwork, but only if the cover matches your risks.
Public liability + employers’ liability
If you take on staff, employers’ liability may be required. Start with: Employers’ Liability Insurance and the cost guide: Employers’ Liability Insurance Cost UK.
Public liability + professional indemnity
If you provide advice, designs, or consultancy, PI can be important: Professional Indemnity Insurance.
Public liability + product liability
If you supply products, product liability may matter: Product Liability Insurance.
How to get cheaper quotes (without weak cover)
Getting cheaper public liability is about improving underwriting clarity and choosing the right limit — not gaming the system. Use the checklist below to improve value while keeping cover reliable.
Cheaper quote checklist
- Write a clear activity description: what you do, where you do it, and what you don’t do.
- Pick the limit your contracts require: don’t overbuy, but don’t underinsure.
- Use a realistic turnover estimate: avoid extreme underestimates.
- Check exclusions: especially for height, heat or specialist work.
- Compare multiple providers: insurer appetite varies, which changes pricing.
- Review annually: if your work mix changes, update your policy accordingly.
What you need to get accurate quotes
Insurers can only price what you declare. To get accurate quotes quickly (and avoid back-and-forth), have these ready:
- Trade + activities (what you do and don’t do)
- Turnover estimate (annual)
- Where you work (domestic, commercial, public areas)
- Cover limit (£2m/£5m/£10m)
- Claims history (if any)
- Any higher-risk details (height, heat, specialist work)
