Arch Handling Your Professional Indemnity Claim? Coverage, Lead/Follow & Policy Wording Disputes
Arch writes Professional Indemnity insurance across both primary and excess layers and on a lead or follow basis, including large complex professional risks and non-standard placements.
Insurance Dispute Service can independently review Arch PI claims where there is disagreement over notification, policy wording, coverage, primary or excess layers, lead/follow arrangements, defence costs, professional liability or indemnity.
£5m
Maximum UK PI line size stated by Arch
Arch writes both complex professional risks and smaller PI accounts across a broad UK appetite.
Arch currently states a maximum Professional Indemnity line size of £5 million. It can write primary and excess cover, consider co-insurance and act on a lead or follow basis across traditional and non-traditional professional risks.
Your Problem
Why are you searching for Arch after a professional indemnity claim?
Usually because the underlying professional allegation has now created a separate question about how Arch's insurance responds.
Notification Dispute
There is disagreement about when the insured first became aware of the matter or when it should have been reported.
Bespoke Wording Dispute
The policy contains manuscript, broker or non-standard wording and the parties disagree about what it means.
Lead / Follow Disagreement
Several insurers participate and it is unclear which insurer's position actually controls the claim.
Excess Layer Issue
Arch provides an excess layer and there is disagreement over whether or when that layer responds.
Defence or Indemnity Disputed
Legal costs, settlement, defence strategy or the amount Arch must fund has become contested.
Who Is Arch?
Arch can insure a straightforward professional business or participate in a sophisticated multi-insurer PI programme.
Arch Insurance provides specialist commercial and professional insurance in the UK and London Market.
Its Professional Indemnity appetite currently includes accountants, design-and-construct firms, estate agents, property professionals, surveyors, insurance brokers, management consultants, media and creative businesses, recruitment consultants, technology firms, architects, engineers and specialist consultants.
Arch states that it can provide both primary and excess coverage, on a lead or follow basis.
It can also consider non-standard coverage and bespoke manuscript policy wording.
That means the Arch name alone does not tell us enough. We need to identify the exact policy, wording, layer and market role involved in the disputed claim.
How Can an Arch PI Claim Develop?
The professional claim and the insurance structure can become complicated at the same time.
A typical journey might broadly look like this.
01
Professional Service
Advice, design, consultancy, surveying or another professional service is provided.
02
Complaint or Circumstance
An allegation, error, complaint or potential claim emerges.
03
Arch Is Notified
Arch receives details of first awareness, the claim, the work and supporting documents.
04
Coverage & Defence
Policy wording, market participation, liability, defence and quantum are considered.
05
Coverage or Market Dispute
A disagreement arises over notification, wording, layer, insurer position, defence costs or indemnity.
Arch expressly writes PI on primary, excess, lead and follow bases.
This is one of the strongest company-specific features on the Arch page.
Arch's current UK PI proposition says it can provide primary and excess coverage for both large complex risks and smaller accounts on a lead or follow basis.
Those concepts matter when a professional claim becomes large.
Arch may be the insurer dealing with the claim from the first pound of insured liability.
Alternatively, another insurer may sit beneath Arch or may lead the placement.
There can also be several insurers participating together.
IDS therefore establishes where Arch sits, whether its layer has attached, whether Arch is leading or following and what Arch's own contractual wording actually requires.
Standard Policy or Bespoke Wording?
With Arch, the precise policy wording may be particularly important.
Arch says it writes traditional professions using its own proprietary policy forms.
But it also expressly states that for appropriate non-standard risks it can provide non-standard coverage and bespoke manuscript wordings.
That makes it unsafe to assume that an Arch PI policy operates in exactly the same way as another Arch policy — or another insurer's policy.
A coverage dispute may turn on individual drafting concerning claims, circumstances, professional services, exclusions, aggregation, defence costs, excesses, limits or notification.
Our starting point is therefore the contract actually issued, not a generic description of Professional Indemnity insurance.
Professional Risks Arch Insures
Arch's UK PI appetite covers both traditional professions and modern specialist services.
Design, engineering, specification and construction-related professional liability.
Valuation, inspection, surveying and property-advice disputes.
Professional claims involving accounting, tax, audit and financial services.
Claims concerning advice, placement and alleged failure to arrange appropriate insurance.
Professional liability arising from specialist technology services and advice.
Management, recruitment, media, scientific, environmental and other specialist professional risks.
What Can Be Reviewed or Challenged?
An Arch PI dispute can require us to test both the claim chronology and the architecture of the insurance contract.
01
Date of First Awareness
What did the insured know and when did the potentially relevant matter first arise?
02
Date Claim Was Made
When did a claimant actually make the professional allegation or demand?
03
Policy Wording
Is Arch relying on wording that genuinely supports the coverage conclusion?
04
Lead / Follow Position
Who leads the market and what effect does that arrangement have on Arch?
05
Primary / Excess Layer
What has to occur before Arch's particular insurance layer responds?
06
Underlying Liability
Does the claimant establish breach, causation and recoverable professional loss?
07
Defence Costs
How do legal and expert costs interact with the excess, deductible and available policy limit?
08
Indemnity
What part of the underlying liability is Arch contractually required to fund?
Arch's PI Claims Team
Arch identifies a dedicated UK Professional Indemnity claims team rather than a general claims contact.
Arch's current UK claims information identifies dedicated Professional Indemnity claims leadership covering both its London Market and UK Regional operations.
Arch says its claims teams are experienced, knowledgeable and empowered to act quickly and decisively.
When reporting a UK Regional PI claim, Arch specifically asks for information including:
the type of work carried out, a summary of the claim or complaint, the date of first awareness, the date the claim was made and the supporting correspondence.
Those are precisely the facts that can later become central to a notification or coverage dispute.
Construction PI
Design · fire safety · remediation · coverage
Arch Construction Professional Indemnity?
Construction and design risks are a significant part of Arch's current Professional Indemnity offering.
Arch's stated PI appetite includes Design & Construct firms, architects, engineers, surveyors, technical services and sustainability/environmental consultants.
Its current PI document library also contains specialist construction questionnaires and specific material concerning cladding and internal fire protection.
Construction PI claims can become especially complex where the allegation involves design defects, fire safety, building-envelope issues, specification, remediation costs, multiple professionals or project-wide losses.
The headline remedial cost is not automatically the amount for which an insured professional is legally responsible.
Liability, causation, apportionment and PI coverage need to be considered separately.
The Problem
Arch is involved in the professional claim, but you may not yet know exactly what Arch insured or what role it is playing.
The underlying allegation may already involve lawyers, experts and potentially substantial damages.
At the same time, questions are developing about notification, policy wording, market leadership or the insurance layer.
If bespoke wording was used, comparing the claim with a generic PI policy may be actively misleading.
The first job is therefore to establish the actual insurance contract, Arch's market role and the precise reasoning behind the disputed position.
The IDS Solution
We reconstruct the Arch policy, insurance placement and professional claim before testing the coverage position.
Insurance Dispute Service can examine the Arch wording, policy schedule, endorsements, underlying or excess policies, notification documents, broker material, coverage correspondence and underlying claimant evidence.
We identify when the matter arose, which policy responds, whether bespoke wording changes the result, whether Arch leads or follows, whether the relevant layer has attached and whether the insurer's coverage position is supported.
Depending on the dispute, the next step may involve a detailed coverage submission, policy-construction argument, insurer negotiation, expert evidence, defence of the professional claim, barrister advice or litigation support.
