Plumbing is one of the most in-demand trades in London’s property market — but also one of the most exposed to risk. A minor installation error or oversight can cause significant property damage, disruption, and financial loss. For both self-employed plumbers and property owners hiring them, professional liability insurance (often called errors and omissions or professional indemnity insurance) provides vital financial protection.
At Fraser Bond, we help property professionals, landlords, and contractors understand how professional liability insurance fits into wider property-risk management — safeguarding not only business reputation but also the value of London’s property assets.
Professional liability insurance protects plumbers, plumbing contractors, and maintenance engineers from claims alleging professional negligence, error, or omission that causes financial loss or damage.
In practice, it covers:
Advice or design errors – e.g., recommending the wrong piping material or system setup that later fails.
Incorrect installation or workmanship advice – when professional judgment leads to water damage, leaks, or costly repairs.
Omissions in system design or compliance – failing to meet UK building or water-safety regulations.
Legal defence costs – covering solicitor fees, settlements, and compensation awarded to clients.
While public liability insurance covers physical accidents or injuries, professional liability focuses on professional error and advice-based risk — an increasingly important protection in London’s high-value property market.
In London’s densely developed, high-value housing and commercial environment, even a small plumbing mistake can have disproportionate financial consequences. Examples include:
A misjudged pressure valve installation flooding a newly refurbished flat.
An incorrect compliance certificate delaying a sale or lease completion.
A developer suing a plumbing subcontractor for a design error causing water system failure.
These cases can lead to claims worth tens of thousands of pounds — or more. For landlords and property managers, engaging only insured contractors ensures protection if workmanship or professional advice results in property loss or tenant claims.
Most reputable UK policies cover:
Negligence, omission, or professional error during plumbing work.
Breach of duty, misrepresentation, or incorrect certification.
Legal defence and settlement costs.
Optional retroactive cover for past work and run-off cover if you cease trading.
Additional protection for loss of documents or breach of confidentiality (in consultancy contexts).
It does not typically cover:
Intentional wrongdoing or fraud.
General bodily injury or property-damage claims (covered under public liability insurance).
Contractual disputes unrelated to negligence.
Several leading UK insurers provide tailored liability cover for tradespeople:
AXA UK – Offers combined public, employers’, and professional indemnity cover for plumbers and contractors.
Hiscox – Specialises in small-business and professional liability protection with flexible limits.
Aviva – Broad coverage for plumbing and building trades, including professional advice exposure.
Simply Business – Online comparison and quote platform popular among sole traders.
Zurich UK – Comprehensive commercial coverage suitable for larger plumbing and facilities companies.
Each insurer’s offering varies in limits, excess, and endorsements — Fraser Bond recommends reviewing these carefully to ensure compliance and sufficient protection for London property work.
When selecting a plumbers’ professional liability policy, consider:
Work Scope & Value – High-end installations or design work in prime London properties warrant higher cover limits.
Client Requirements – Many landlords, developers, and estate managers now require proof of professional indemnity before contract award.
Cover Limit – Start at £250,000–£1 million; large commercial projects may require £2 m–£5 m.
Retroactive Coverage – Ensures earlier work remains protected.
Insurer Reputation & Sector Knowledge – Choose providers experienced in UK trade liability and building services.
Combine With Public & Employers’ Liability – Comprehensive protection for both physical and professional risk.
