Expert protection for your professional liabilities
Professional indemnity insurance, or PII, is a crucial safeguard in the complex world of architectural design and construction.
It offers the reassurance that if a client accuses you of mistakes in your services, you have protection from the financial fallout, with legal defence costs and compensation covered.
We’ve been helping architects secure insurance and manage their risks for three decades. We’re one of the leading brokers in architects’ PII, and the preferred PII broker for the Association of Consultant Architects (ACA).
Do architects need professional indemnity insurance?
All practising architects need PII, as a regulatory requirement. The Architects Registration Board (ARB), which governs the architect profession, expects its members to have adequate and appropriate PII.
This is to protect you, your firm, and your clients if mistakes happen in your professional services and action is taken against you.
What does professional indemnity insurance cover?
Architects’ PII protects you if clients make a claim against you for negligent services. This could be for anything from errors in design plans or drawings to not spotting issues that ultimately lose the client money.
PII covers legal costs, including your defence and court costs, and damages and settlements that result from the claim. Cover can include:
- Negligence or breach of duty of care
- Misrepresentation
- Defamation
- Unintentional confidentiality breaches
- Intellectual property infringements
Also be aware of what isn’t covered (exclusions), cover that may be restricted, and policy limits and sub-limits. This may be relevant to, for example, projects involving cladding, asbestos, or buildings over a certain height.

Architects professional indemnity FAQs
An architecture firm's PII policy will usually provide cover for its staff when carrying out the firm's work.
If you're a consultant or architect working through an agency, check with the firm you are acting for to make sure their PII policy covers you. Without cover you would be held liable for costs if a client accuses you of mistakes in your work – which could be extremely costly.
Bear in mind that if you carry out private work outside of your employer’s firm, their policy is unlikely to cover you for this activity. So you’d need to take out your own policy to cover this work.
Professional indemnity insurance runs on a claims-made basis. This means your cover is for when a claim is made, rather than the time the incident happened. To cover you for claims after a practice closes or you retire, you or your firm will need run-off cover.
If you’re practising in England or Wales, run-off cover needs to last at least six years, or five years in Scotland, in line with ARB rules. However, the length of time you need run-off insurance will also depend on the contracts you've entered into in the past.
Without cover in place, you could face financially ruinous costs if a disgruntled former client makes a claim against you. Also consider that if you are still taking on the odd project, you're still practising (even if it’s free of charge) and need PI beyond just run-off cover.
Professional indemnity insurance policies usually last for a term of 12 months. You will then need to arrange cover for another year.
It’s best to prepare for this ahead of time and understand your practice’s risk profile. Your broker can explain how they will approach your renewal and any extra information they need to get you the best policy for you.
For example, this might be new systems you’ve put in place, or updated procedures or training, which helps demonstrate improvements to your risk profile.
The ARB expects architects to have a minimum level of £250,000 indemnity for each claim, with some limitations allowed for cover for cladding and fire safety claims.
Even so, your cover amount needs to be enough to meet any potential claims against you. It should be in line with the level of risk your practice faces, with careful consideration needed to the nature and scale of your work, and compensation worst-case scenarios.
We can help you assess your profile and advise on the level of cover you need.
