Quick answer: £5m vs £10m — which should you choose?
Your clients accept £5m, you’re doing typical commercial or subcontract work, and you want a solid “site-ready” level that covers many contractor requirements.
Your contract, framework, council/public sector work, or stricter procurement process requires it — or you want to remove insurance as a barrier to higher-value commercial jobs.

What’s the real difference between £5m and £10m public liability?
The limit (sometimes called the “indemnity limit”) is the maximum the policy will pay for covered claims, subject to the policy terms. The practical difference is rarely about day-to-day work — it’s about contract access and worst-case claim severity.
| Topic | £5m public liability | £10m public liability |
|---|---|---|
| Typical use | Commercial clients, subcontracting, many site requirements | Public sector, councils, strict procurement, higher-footfall environments |
| Contract acceptance | Often accepted by many contractors | Accepted where £10m is mandatory (no negotiation) |
| Risk tolerance | Strong baseline for many trades | More headroom for severe claims |
| Cost impact | Usually cheaper than £10m | Often higher, but sometimes the uplift is smaller than expected |
| Best for | “Site-ready” trades wanting value | Winning stricter work + reducing onboarding friction |

Who typically asks for £10m public liability (and why)?
£10m requirements usually come from procurement rules, risk management policies, or insurer requirements tied to high-footfall or public environments. The common thread: the client wants to reduce risk exposure if a severe incident occurs.
Common “£10m required” environments
- Councils / local authorities and some public sector tenders
- Facilities management contracts with strict onboarding packs
- High-footfall sites (public buildings, busy commercial premises)
- Large main contractors with standard subcontractor requirements
- Landlords / property management groups with a fixed insurance threshold
If a client asks for £10m, they often won’t accept £5m “because you’re careful”. They need the certificate to match their requirement. Proof info here: PL certificate guide.
Decision checklist: choose the right limit fast
Use this checklist to decide in 60 seconds. When in doubt, let the contract requirement decide — it’s the simplest and safest rule.
- Read the contract / onboarding email: does it state £5m or £10m?
- If it states £10m: choose £10m (otherwise you may fail onboarding).
- If it states £5m: £5m is usually enough — unless you’re targeting stricter work soon.
- Where do you work? High-footfall/public environments often push toward £10m.
- Do you want “friction-free” tendering? £10m can remove objections in stricter procurement.
- Compare the uplift: quote both and see if £10m is a small step up.
If you’re doing regular commercial work and want broad acceptance: start with £5m, then upgrade when a £10m contract appears.
If you’re aiming for councils/frameworks or big contractors: price £10m now to avoid losing jobs on insurance paperwork.
Cost impact: what usually changes when you upgrade from £5m to £10m?
The upgrade cost depends on your trade, turnover, claims history, and where you work. Sometimes the uplift is modest; sometimes it’s meaningful. The only reliable way to know is to compare both limits with the same details.

Factors that can change the uplift
- Trade risk: higher severity trades can see a bigger difference.
- Commercial/site exposure: public areas and large sites can price differently.
- Turnover: higher turnover can increase overall premium and the uplift.
- Claims history: claims can reduce insurer appetite at higher limits.

Proof of cover: what your certificate must show
When a client asks for £10m, they’re usually checking your certificate — not your explanation. Your certificate should clearly show the policyholder name, limit of indemnity, and policy dates.
| Certificate item | What clients check | Common fail |
|---|---|---|
| Limit of indemnity | Must show £5m or £10m as requested | Certificate shows £5m when £10m is required |
| Policyholder name | Must match your invoicing/onboarding name | Sole trader vs Ltd mismatch |
| Policy dates | Must be active on the job date | Expired certificate saved and resent |
| Activities (if shown) | Should match the work you’re doing | Too vague (“contractor”) causes questions |

FAQs
Is £10m public liability necessary in the UK?
Not always. Many trades operate successfully with £2m or £5m. £10m is usually required by certain clients (councils, public sector, strict procurement) or specific contracts. If your contract requires £10m, you should match it.
Does £10m public liability cost much more than £5m?
It depends on your trade, turnover, where you work, and claims history. Sometimes the uplift is modest; sometimes it’s larger. The best approach is to quote both limits with the same details and compare.
Can I send a £5m certificate if the client asked for £10m?
Usually no. Many onboarding teams check the certificate limit and will reject it if it doesn’t match the requirement. See: PL certificate guide.
What if I switch between £5m and £10m depending on the job?
Some businesses do exactly that: maintain £5m for general work and upgrade when needed for specific contracts. Check how quickly your provider can issue updated certificates and confirm any policy changes before committing.
Does public liability include employers’ liability?
Not automatically. Employers’ liability is usually separate or an add-on. If you employ anyone, you may need it: Employers’ Liability Insurance.
