THE SHORT ANSWER

High-limit Professional Indemnity insurance provides $5M, $10M and $20M+ PI cover for engineers, consultants and design firms whose contract specifies a limit their current insurer cannot write. It raises the ceiling on the same PI protection - cover for financial loss claimed from your professional advice, designs or services - by reaching the specialist underwriters with genuine appetite for higher limits.

A decline or a limit your insurer cannot increase reflects one insurer's appetite, not the whole market, so hard-to-place and non-renewed risks can often still be placed with the right specialist underwriter.

A contract asks for a limit your current insurer cannot write. High-limit Professional Indemnity is about reaching the specialist underwriters who actively write $5M, $10M and $20M cover.

Limits That Meet Your Contract

Commercial, government and Tier 1 contracts often specify the exact PI limit you must hold. We read the insurance clause and arrange cover that meets it, on time.

When the Market Says No

A decline or a limit your insurer cannot increase reflects one insurer's appetite, not the whole market. Declined or non-renewed PI can often be placed with the right specialist underwriter.

WHY TANK INSURANCE

Why firms come to us for higher limits

When a contract demands a limit your current insurer cannot write, the answer is rarely the direct market. We map the specialist underwriters with genuine appetite for higher limits, present your risk properly, and compare terms so you are not paying a single insurer's premium for cover that several markets will write.

01

Specialist Capacity

We work with underwriters who actively write $5M, $10M and $20M PI for professional and construction-adjacent risks, well beyond standard direct limits.

02

Contract Clause Review

We read the insurance clause in your contract and arrange a limit, retroactive date and wording that actually satisfies it - not just a higher number.

03

Hard-to-Place & Declined

Declined or non-renewed at a higher limit? We regularly place cover other insurers stepped back from by taking the risk to the right specialist market.

04

Deadline-Driven Turnaround

Contract deadlines do not wait. Straightforward risks can often be quoted the same day, with the market mapping ready when you need to sign.

WHO THIS IS FOR

When you need a higher PI limit

High-limit PI is usually triggered by a contract, a project or a renewal - not by fee income alone. These are the situations we place most often.

Engineers and consultants whose contract specifies a $5M, $10M or $20M PI limit
Firms whose current insurer cannot increase their limit at renewal
Design and construct builders taking on design responsibility
Practices tendering for government or Tier 1 contractor work
Consultants pursuing larger projects than their existing cover allows
Businesses whose limit was reduced or restricted at renewal
Professionals declined for higher limits in the direct market
Firms needing a higher limit at short notice to sign a contract

POLICY SCOPE

What High-Limit PI Insurance Covers

A higher limit raises the ceiling on the same Professional Indemnity protection - cover for financial loss claimed from your professional advice, designs or services.

Usually Covered

βœ“ Professional negligence, errors and omissions up to the higher limit
βœ“ Legal defence costs, including for unproven claims
βœ“ Design, calculation and documentation errors
βœ“ Advice causing financial loss to clients or third parties
βœ“ Contract-required limits for commercial and government work
βœ“ Retroactive cover for past work (where the date is preserved)

βœ• Property damage or bodily injury (Public Liability covers this)
βœ• Contractual guarantees beyond reasonable professional duty

This is a general guide only. What is and isn't covered depends on the terms, conditions, limits and exclusions of your specific policy.

CREATIVE STRUCTURING

More than one way to reach the limit

A single insurer is not the only path to a higher limit. Because we work across a range of insurer securities and binders, we can build the cover you need by layering markets and structuring the excess to suit the risk. When a contract demands a limit the direct market will not write on its own, there is usually a way to construct it.

Excess layers - building a tower

If your primary policy is $5M and you need $10M, a second insurer can sit on an excess layer above it - written as "$5M excess of $5M", or a "5 x 5". The excess insurer responds once the primary limit is used up. Layers can be stacked further to reach $15M, $20M and beyond.

We can place that 5 x 5 with a different insurer to the primary, because we hold access to multiple insurer securities and binders rather than relying on a single market. That access is what makes higher towers possible.

Large self-insured excess for big PI

For larger PI risks, carrying a higher self-insured excess - the amount you contribute to a claim - can open up markets and help manage premium. We can structure excesses such as $10k, $50k, $100k or $200k where it suits the risk and the balance sheet behind it.

We have quoted self-insured excesses up to $500k for large PI programmes. The right level depends on your financials, claims history and the cover you are trying to achieve - and we will model the trade-off with you.

The point is simple: there is rarely just one way to structure high-limit PI. Tell us the limit and excess you need and we will map the options across the market.

CORPORATE ADVISORS & TRANSACTION WORK

High limits for M&A and corporate advisory work

For M&A advisers, transaction advisers, business valuers and capital-raising consultants, the limit is driven by the size of the deal, not your fee income. A single error in a valuation, model or disclosure can flow into a loss many times your engagement fee, which is why advisory mandates routinely call for $5M, $10M or $20M of cover - and why the wording detail matters as much as the number.

The Detail That Matters

Beyond the headline limit

  • β†’Costs-inclusive vs costs-in-addition - whether defence costs sit inside or on top of the limit changes what the cover is really worth
  • β†’Retroactive date - preserving it so past advisory work stays covered when you move insurer
  • β†’Certificate timing - getting the certificate of currency issued before you have to sign the mandate
  • β†’Insurer capacity - reaching markets with appetite for advisory risk at the higher limit

How We Reach It

Capacity for advisory risk

Generalist markets often step back from corporate advisory work, so the higher limit comes from specialist financial-lines underwriters - and, where one market cannot reach the figure alone, from layering an excess policy above the primary. We map that capacity and structure it to the mandate.

  • βœ“Specialist markets that write M&A, valuation and capital-raising PI
  • βœ“Excess layers to reach $10M, $20M and beyond
  • βœ“Wording matched to what your counterparty actually requires

QUESTIONS

High-Limit PI - Frequently Asked Questions

Many commercial, government and Tier 1 contracts specify the exact Professional Indemnity limit you must hold - commonly $5M, $10M or $20M. Your required limit is set by what the contract specifies and by the financial loss a claim could cause, not just your fee income. We read the insurance clause in your contract and arrange a limit that meets it.
Insurers set internal capacity limits by occupation and risk profile. When you ask for a higher limit, your existing insurer may have reached the maximum it can write for your discipline, or it may price the increase well above the wider market. That does not mean the limit is unavailable - it often means the risk needs to be taken to specialist underwriters who have appetite for higher limits.
No. Premium does not scale in a straight line with the limit. Moving from $5M to $10M, for example, usually costs far less than double, because the additional layer of cover is statistically less likely to be eroded. Pricing for the same high limit can also vary widely between insurers, so it pays to compare specialist markets.
Often, yes. A decline or non-renewal from one insurer reflects that insurer's appetite, not the whole market. We regularly place cover for firms that have been declined elsewhere by mapping the specialist underwriters who actively write higher limits for that profession and presenting the risk properly.
Typically your profession and services, annual fee income, your largest project or contract value, claims and circumstances history, current insurer and limit, the retroactive date you need to preserve, and the contract or client requirement driving the limit. Having this ready lets us approach the market quickly when a deadline is close.
Straightforward risks can often be quoted the same day or within 24 to 48 hours once we have the required information. If you have a contract deadline, tell us the date and we will prioritise the markets most likely to meet it.
Yes. We can place an excess layer above your primary policy - for example $5M excess of $5M (a '5 x 5') to reach $10M - often with a different insurer to the primary, because we work across multiple insurer securities and binders. Layers can be stacked further to reach $15M, $20M and beyond.
Often, yes. Carrying a higher self-insured excess (the amount you contribute to a claim) can open up markets and help manage premium on larger PI risks. We can structure excesses such as $10k, $50k, $100k or $200k, and have quoted up to $500k for large programmes - the right level depends on your financials, claims history and the cover you need.
For M&A advisers, transaction advisers, valuers and capital-raising consultants, the limit is driven by the size of the deals you advise on, not your fee income - a single error can flow into a loss many times your engagement fee. These limits commonly sit at $5M, $10M or $20M, and a mandate, lender or counterparty often specifies the figure you must hold to act. See our corporate advisor PI hub.
Yes. We regularly step a limit up to meet what a mandate or counterparty requires, and step it back afterwards if appropriate. When we do, we check the detail that actually matters: whether the limit is costs-inclusive or costs-in-addition, the retroactive date is preserved, and the certificate of currency can be issued in time for you to sign. Tell us the deadline and we prioritise the markets most likely to meet it.
Corporate advisory, M&A, transaction and capital-raising work sits outside the appetite of most generalist PI insurers, so a generalist market may exclude the advisory activity or step back at renewal. That reflects one insurer's appetite, not the whole market. The same risk can usually be placed with a specialist financial-lines underwriter who actively writes advisory work - see corporate advisor PI.
