Trade Business Insurance UK — What Cover Do You Actually Need as a Tradesperson? (2026)

The Six Main Types: Compulsory vs Recommended

Only one type of trade insurance is a legal requirement in the UK. Everything else is commercially expected, contractually demanded, or simply prudent. Here is where each policy sits:

Public Liability Insurance

Public liability (PL) insurance covers you if your work causes injury to a third party or damage to their property. It is not a legal requirement — but it might as well be. Almost every client, managing agent, main contractor, local authority, and housing association will refuse to let you start work without seeing your certificate. Without it, you will not access commercial sites, managed properties, or any public sector contract.

What typical claims look like

• A plumber's poorly fitted compression fitting fails over the weekend. Water floods through the ceiling into the flat below. The insurer pays for the neighbour's damaged ceiling, flooring, and contents.
• A customer trips on an electrician's cable drum left across a hallway and breaks their wrist. The claim covers compensation and legal costs.
• A roofer's tile slides off scaffolding and damages a parked car below. PL pays for the vehicle repair.
• A decorator leaves a dust sheet on a staircase; the homeowner slips. Medical costs and compensation fall to your PL policy.

Cover levels: what level for what job

PL cover comes in £1m, £2m, and £5m indemnity levels. £1m is now considered the bare minimum for solo domestic work — a single serious personal injury claim can easily exceed this. Here is how to match your level to your work:

The price difference between £2m and £5m cover is usually £50–£100 per year. Go to £5m as your default — it keeps every door open and costs very little more.

What PL does NOT cover

• Your own tools, equipment, or vehicle
• Your own injury or illness
• The cost of redoing faulty workmanship — only the consequential damage it causes (e.g. water damage from a leaky pipe you installed) is covered
• Contractual liability beyond what common law already provides
• Deliberate acts
• Work above certain heights or below certain depths without a specific endorsement — check the policy wording for your trade

Typical cost for a sole trader: £100–£200/year for low-risk trades, £300–£500/year for higher-risk trades (roofing, gas engineering, groundwork). A growing team will pay proportionally more as turnover rises — insurers price on the volume of work, not just the trade type.

Employers' Liability Insurance

Employers' liability (EL) is the only type of trade insurance that is a clear legal requirement in England, Scotland, and Wales. Under the Employers' Liability (Compulsory Insurance) Act 1969, if you employ anyone you must hold a policy with a minimum indemnity of £5 million. Almost all policies provide £10 million as standard.

The Health and Safety Executive enforces this. The fine for operating without valid EL cover is £2,500 for every day you are uninsured. A separate £1,000 fine applies if you fail to display or make available your EL certificate. The HSE can inspect at any time and your certificate must be produced on request.

Who counts as an "employee" for EL purposes?

This is where many tradespeople get caught out. The legal definition of employee for EL purposes is broader than the employment law definition. HMRC's employment status rules and your EL insurer's definition do not always align. You will likely need EL cover for:

• Full-time and part-time employees — straightforward.
• Apprentices — even if unpaid.
• Casual or day-rate labour — anyone you hire informally by the day or week.
• Labour-only subcontractors (LOSCs) — if they use your tools, work under your direct instruction, and are integrated into your operation rather than running their own business independently, they may be treated as employees under EL law even if both parties call the arrangement "subcontracting."
• Family members working in the business — even if not paid at a commercial rate.
• Work experience placements.

If you are unsure whether someone you use regularly falls under your EL cover, speak to a specialist trade insurance broker before assuming it is fine. The potential fine and the potential claim are both significant.

Professional Indemnity Insurance

Professional indemnity (PI) insurance covers claims arising from errors in advice, design, or professional specification that cause a client financial loss. Public liability covers physical damage and injury; PI covers the financial consequences of getting something wrong in an advisory or design capacity.

The trades most exposed include:

• Heating engineers doing heat loss calculations or system design — specify an undersized heat pump for a commercial building and you own the remediation cost
• Electrical contractors designing distribution systems — particularly on commercial or industrial installations
• Builders project-managing design-and-build contracts
• HVAC engineers designing ventilation and air conditioning systems
• Structural engineers and surveyors
• Solar and EV charging installers providing system sizing advice

PI is a "claims-made" policy — meaning it covers claims made during the policy period, not necessarily when the work was done. You need to keep PI live even after a project ends if there is any possibility of a late claim. Run-off cover extends protection after you stop trading or switch insurer.

Typical costs: £200–£400 per year for £250,000 indemnity for a sole trader in a lower-risk trade. Structural engineers and specialist designers pay considerably more. Many main contractors and public sector clients now require PI alongside PL as a condition of award — particularly on design-and-build contracts.

Tools and Equipment Insurance

Tools cover is one of the most underinsured categories in the trades — and the most likely to result in a significant out-of-pocket loss. A full kit for an electrician, plumber, or heating engineer can easily run to £10,000–£25,000. A van break-in can put you out of action for days while you wait for replacements and absorb the excess.

What is typically covered

• Tools in transit — in your van or on your person while travelling to jobs
• Tools on site — on a customer's premises or a construction site during working hours
• Own plant — generators, compressors, small powered equipment you own
• Hired-in plant — equipment rented from a hire company; damage liability while in your custody

Critical exclusions to read before buying

• Unattended vehicles overnight — most policies exclude tools stolen from an unattended vehicle between defined hours (typically 9pm–6am). Some go further and exclude tools left in any unattended vehicle regardless of time. This is the single most common reason a tools claim is rejected — it is the scenario most likely to happen to you.
• Insecure storage — tools left in an unlocked van, on an unsecured site, or in a building without adequate security may not be covered.
• Individual item limits — many policies cap payouts at £500–£1,000 per individual item, which will not cover high-value multimeters, thermal cameras, or specialist testing equipment.
• Wear and tear — sudden loss or damage only; gradual deterioration is not covered.
• Mechanical breakdown — not covered; falls under manufacturer warranty or service contracts.

Practical steps to reduce premiums and improve terms: install a tool vault in your van, use deadlocks and slam locks, mark all tools with your postcode using an engraver, and maintain a photographic inventory updated annually. Some insurers offer better terms or lower premiums if you can evidence these measures. Review your sum insured every year as new kit is added — outdated coverage is as good as no coverage.

Typical cost: £100–£250 per year for £3,000–£5,000 of cover; £200–£400 per year for £10,000+ of cover. Specialist providers to compare: Ripe, Direct Line for Business, NFU Mutual, and simply comparing via Simply Business.

Commercial Vehicle Insurance

Every vehicle used on a public road must be insured — this is a legal requirement. But the class of use you declare is critical, and getting it wrong can invalidate your cover entirely at the point of a claim.

Declaring the correct use class

A Social, Domestic and Pleasure (SDP) policy — or even SDP plus commuting to a single fixed site — does not cover a tradesperson driving between multiple customer locations. You need commercial vehicle insurance with business use declared:

• Class 1 (SDP + commuting): covers travel to one fixed workplace. Not sufficient for anyone visiting multiple sites.
• Class 2 (business use): covers travel between multiple work locations in your own trade. The minimum for most tradespeople.
• Class 3 (commercial travelling): for vehicles used as the primary trading vehicle or carrying goods for commercial purposes. Some higher-risk trades or materials-delivery operations need this class.

Using a vehicle for trade work on a personal SDP policy is one of the most common reasons a claim is rejected. Insurers check mileage, occupation, and patterns of use. The saving on premiums is not worth the risk — if an accident happens while you are attending a job, the insurer will investigate and may decline the claim entirely.

Tool theft from your van

Your commercial vehicle policy almost certainly does not cover tools stolen from the van. Van insurance covers the vehicle; a separate tools policy covers the contents. Some combined trade insurance packages bundle both — if yours does, compare the tools cover terms carefully, particularly around overnight exclusions, before assuming you have adequate protection.

Personal Accident and Income Protection

This is consistently the most underused insurance category among tradespeople — and the one that generates the most regret when something goes wrong. As a self-employed tradesperson, there is no statutory sick pay. If you cannot work, your business stops earning. A broken wrist, a back injury, or a respiratory illness can eliminate your income for weeks or months with no floor beneath you.

Income protection insurance

Income protection pays a monthly benefit — typically 50%–70% of your pre-illness income — after a defined deferred period (commonly 4, 8, or 13 weeks) if you are unable to work due to illness or injury. Payments continue until you return to work or until the benefit period expires. Some policies pay to retirement age (65 or 67); others cap the benefit period at 1, 2, or 5 years.

The definition of "unable to work" matters enormously. An own-occupation policy pays out if you cannot perform your specific trade — the most generous definition, and the one worth paying for. An any-occupation policy only pays if you cannot do any work whatsoever — much harder to claim on and far less valuable for a tradesperson.

Personal accident insurance

Personal accident insurance pays a lump sum for permanent disability, loss of a limb, loss of sight, or accidental death. It is simpler and cheaper than income protection but provides no sustained monthly income replacement. Many tradespeople hold both: income protection for ongoing illness or injury that keeps them off work, and personal accident for more severe events.

Typical costs: £30–£80 per month for income protection for a tradesperson in their 30s covering £2,000–£3,000/month benefit; £10–£30 per month for a personal accident policy providing a £100,000–£250,000 lump sum. Premiums increase with age and pre-existing health conditions.

The arithmetic is straightforward: if income protection costs £60/month and pays £2,500/month for the three months you spend recovering from a back operation, the policy has returned 17 years of premiums in a single claim. It is not a luxury — it is the difference between keeping your business and losing it.

How to Buy: Brokers vs Comparison Sites

For straightforward sole trader public liability cover in a low-risk trade, a comparison site will get you a competitive price quickly. For anything more complex — higher-risk trades, design-and-build work, multiple cover types, subcontractor arrangements, unusual equipment, or commercial contracts requiring specific wording — a specialist trade insurance broker is a significantly better option.

Brokers worth knowing for UK trades:

• Simply Business — strong online platform, good for sole traders and small teams across most trades; comparison-style with broker support
• Tradesman Saver — specialist in trades, with a good understanding of trade-specific exclusions and requirements
• Hiscox — strong for professional indemnity and higher-value commercial cover; available direct and via brokers
• AXA Business Insurance — broad coverage, good for combined packages; competitive across many trade types
• Qdos Contractor — specialist in self-employed and contractor cover including IR35 considerations for those operating via limited companies

A good broker earns their place by understanding your actual work, not just your job title. They ensure the policy wording covers the specific activities you perform, that height or depth restrictions do not exclude your normal working methods, that subcontractor arrangements are declared correctly, and that cover levels match what your contracts require. This matters at claim time far more than it matters at premium time.

Common Mistakes That Lead to Rejected Claims

• Underinsuring tools. Buying £3,000 of tools cover when your kit is worth £12,000. In the event of a total loss you absorb the shortfall personally. Review your sum insured every year — it drifts as you buy new equipment.
• Not notifying the insurer of subcontracting. If you regularly bring in subcontractors, your insurer needs to know. Some policies exclude or limit cover when subbies are involved; others require the subbies to hold their own PL. Failing to declare this voids your cover on jobs they are involved with.
• Letting cover lapse mid-contract. A late renewal, a bounced payment, or switching insurer without checking continuity creates a gap. Any incident in that window falls on you personally. Set renewals in your calendar 30 days out and treat them as a non-negotiable business deadline.
• Wrong use class on the van. Insuring a trade van on SDP or SDP plus commuting is one of the most common errors. If an accident happens while attending a customer job, the insurer will check — and may decline the claim.
• Not declaring all business activities. A plumber who takes on occasional gas work needs a policy that covers gas. A decorator who takes on damp treatment needs that declared. If your insurer does not know about an activity and a claim arises from it, you have a problem.
• Assuming EL does not apply to casual labour. Labour-only subcontractors integrated into your operation may be treated as employees under EL law regardless of how you both describe the arrangement.
• Skipping income protection as a "nice to have." Every self-employed tradesperson is one injury away from zero income. The premium is modest; the cost of not having it is not.

What Level of Cover for What Job Type?

The cover level you need is driven by the type of client and contract, not just your trade. Here is a practical guide:

If you are tendering for a mix of domestic and commercial work, align your cover to the highest-requirement contract you want to be able to win. Upgrading mid-project when a client asks for a higher limit is possible but disruptive — and carries a mid-term adjustment premium. Build headroom in at each renewal.

Insurance Requirements Under CIS

When working under the Construction Industry Scheme (CIS) as a subcontractor to a main contractor, your insurance requirements are set by the main contractor's own obligations and risk management processes — not just by statute.

Before you start on site under CIS, most reputable main contractors will require:

• Public liability certificate — almost always £5m minimum; some specify £10m
• Employers' liability certificate — if you bring any labour with you, non-negotiable and will be checked before you start
• Professional indemnity — if your scope includes any design or specification
• Evidence that cover will remain current for the duration of the contract — not just a one-time upload at pre-qualification stage

Many main contractors run supply chain pre-qualification systems — Constructionline, CHAS, SafeContractor, Acclaim — that require you to upload and maintain your insurance certificates as part of ongoing approval. Letting your policy lapse or failing to upload a renewed certificate can result in suspension from their approved list, which effectively bars you from their sites.

One further point specific to CIS: operating as a CIS subcontractor does not automatically make you an employee of the main contractor for EL purposes — but it does not automatically make you independent either. If you work exclusively for one contractor, use their equipment, and work under their direct supervision rather than running your own operation, HMRC and your insurer may view your status differently than you do. This is worth understanding before an incident forces the question.
