A softening insurance market is usually good news. Howden's July 2026 report on architects' professional indemnity cover describes exactly that: capacity returning, competition improving and premium pressure easing for UK practices after several difficult renewal cycles. The complication is that the underlying liability has not softened at all.
Building Safety Act liability can reach back up to 30 years, and the report finds claims are becoming more complex and more costly to resolve. For a practice buying architects professional indemnity insurance UK cover this year, the cheaper premium is not the headline. The documentation behind it is.
Why architects' professional indemnity cover matters right now
Soft markets are temporary and liability is not. Howden's July 2026 report describes improving conditions for UK architects, with underwriters more willing to quote and renewal terms easing. None of that changes the exposure a practice already carries on projects it completed years ago, and a practice that reads a lower premium as a lower risk has misread the market.
The long tail is the defining feature. Building Safety Act liability reaching back up to 30 years means a claim can arrive about work signed off by people who have since retired, under standards that have since changed. The practical question is whether the practice can still produce the records that show what was designed, what was advised and who decided.
Claims themselves are getting harder. The report points to more complex and more costly claims, which in practice means longer investigations, more parties and more argument about scope and reliance. That is where construction professional risk management earns its keep: the cost of a claim is driven as much by how well a practice can evidence its position as by the underlying error.
Key takeaways
- Howden's July 2026 report finds a softening professional indemnity insurance market for UK architects after several hard renewal cycles.
- Building Safety Act liability can reach back up to 30 years, so cover bought today sits over decades of completed work.
- The report finds claims are becoming more complex and more costly, lengthening investigations and raising defence costs.
- A softer market changes the premium, not the exposure, and underwriters still price on demonstrated risk management.
- Documentation is the practical defence: contemporaneous records of advice, decisions and scope decide how a claim resolves.
What this means for architects, engineers and AEC consultancies
For architects, the softening market is an opportunity to renegotiate rather than relax. Better terms are available, but underwriters reward practices that can describe their procedures and show them working. The PI insurance an architecture practice secures this year will depend less on its claims history than on how convincingly it answers questions about documentation, sign-off and scope control.
Structural and civil engineers face the same long tail from a different angle, and so do the contractors and design-and-build teams they work alongside. Where responsibility for a design decision is shared, the party with the clearest record of what it advised and when tends to end up carrying least of the eventual cost.
For AEC consultancies, the exposure is organisational. Records sit in individual inboxes, project folders and superseded systems, and the practice discovers the gaps only when a notification arrives. Treating audit trails as part of normal project administration, rather than something assembled retrospectively under pressure, is the cheapest risk control available to a practice.
Document advice as you give it
Contemporaneous notes carry far more weight than reconstructions written after a notification. Record what was advised, what was instructed against that advice, and the date, inside the project record rather than in personal email.
Keep records for the long tail
With liability reaching back up to 30 years, retention policies built around a single insurance cycle are inadequate. Decide now where completed project records live, who can retrieve them and how they survive a system migration.
Use renewal to price your controls
A softening market gives practices leverage. Present procedures, documentation standards and scope controls as evidence at renewal, and ask brokers directly which of them the underwriter actually credited in the quotation.
How should a practice evidence its professional risk management?
Evidence is the difference between a defensible position and an expensive one. The comparison below is not about insurance products but about where the record of a project lives, how quickly it can be retrieved years later, and whether it shows who decided what and when.
| Capability | Spreadsheets | Separate point tools | Quantim |
|---|---|---|---|
| Decision and advice audit trail | Scattered across files and inboxes | Logged in one discipline's system only | Time-stamped record against each project |
| Retrieval of closed project records | Depends on who still works there | Export needed before archive access | Closed projects stay searchable in place |
| Scope and variation history | Tracked by email thread, if at all | Change log separate from fee data | Variations linked to fees and instructions |
| Evidence pack for a notification | Assembled manually under time pressure | Partial, needing cross-system stitching | Reporting pulls the project history together |
| Renewal submission evidence | Rewritten from memory each year | Metrics limited to one workflow | Dashboards show procedures in actual use |
How Quantim helps
Quantim's contribution here is unglamorous and specific: the project record. Project management and timesheets capture what was done, when and by whom, while reporting and dashboards make that history retrievable rather than merely stored. For a practice carrying long-tail liability, the value is being able to answer a notification from the record itself instead of reconstructing events from memory and personal email.
The same audit trail supports due diligence at renewal. Fee management and cost control show how scope changes were agreed and priced, which is often the disputed point in a claim about additional work or reliance. Demonstrating that documentation is routine rather than retrospective is a far stronger position than simply asserting that procedures exist.
- Audit what you can still retrieve. Pick three completed projects from different years and try to produce the design decisions, advice given and sign-offs. Where that fails, you have found your actual exposure.
- Set retention to match the long tail. Building Safety Act liability can reach back up to 30 years, so agree a retention period and a storage approach that outlast staff changes and system replacements.
- Take evidence to your next renewal. Compile the procedures you follow and the records that prove it, then ask the broker which controls improved the terms. A softening market is the moment that question gets answered honestly.

Request a demoA softer market lowers the premium, not the exposure. With liability reaching back up to 30 years, the record a practice keeps today is the defence it will rely on.
“Our renewal came in lower this year, which was welcome, but the underwriter's questions were all about documentation. Two of them concerned projects completed before our current systems existed. We spent longer assembling that history than negotiating the premium, and it changed how we file things now.”

Checklist for practice leaders
- Record design advice and client instructions in the project file on the day they happen.
- Set a records retention period that matches long-tail Building Safety Act liability.
- Test retrieval on three closed projects from different years and note what is missing.
- Keep scope changes, variations and fee agreements linked to the decisions that caused them.
- Prepare a renewal evidence pack describing procedures actually in use, not aspirations.
- Ask your broker which risk controls the underwriter credited when pricing your cover.
Frequently asked questions
How can a practice reduce professional indemnity claims risk?
Mostly by improving the record rather than the design process. Howden's July 2026 report finds claims becoming more complex and more costly, and complexity is where documentation decides the outcome. Capture advice and instructions contemporaneously, keep scope and variations linked to the fee they sit under, and make sure closed projects remain searchable years later. Add a clear sign-off trail so it is obvious who approved what. None of that prevents an error, but it shortens investigations, narrows the dispute and gives the insurer a defensible position to work from. Full details are published in Howden's 2026 architects' professional indemnity market report.
What does Building Safety Act liability mean for architects?
In practical terms it extends how far back a claim can reach. Howden's July 2026 report describes long-tail Building Safety Act liability extending up to 30 years, which changes two things for an architecture practice. First, cover bought today sits above decades of completed work, so the premium is only part of the picture. Second, record keeping becomes a long-term obligation rather than a project-stage task: the staff who made a decision may have left, and the systems holding the evidence may have been replaced twice.
Does project documentation software help with risk management?
It helps when documentation is a by-product of normal work rather than an extra task. The failure mode in most practices is not an absence of records but their distribution: decisions in email, drawings in one system, instructions in meeting notes nobody filed. Software that keeps project management, timesheets and fee records in one place produces a single retrievable history by default. The test is whether someone who was not involved can reconstruct a project's decisions years afterwards without interviewing anybody, because that is what a claim requires.
A softening market is a good moment to look past the premium. Howden's July 2026 report is, read closely, less about pricing than about evidence: complex claims, a 30 year tail and underwriters who increasingly want to see procedures working rather than described. The practices that benefit most will be the ones already filing properly. Explore the features and benefits of Quantim to put your project records on a defensible footing.
