PI insurance for UK property developers — the professional-services boundary

Property developers occupy a distinctive PI position — not typically holding architectural or engineering qualifications but often providing professional-services-like input via project management, design coordination and consultancy. This page maps the boundary.

The professional-services boundary

1. Property developers are typically not covered by conventional professional indemnity for their pure development activity — that's development-business risk.
2. Where the developer provides professional services (project management, design coordination, consultancy input), that activity may attract PI cover.
3. Standard developer insurance covers construction, contract works, and public liability.
4. Professional advisers to developers (architects, engineers, cost consultants) hold their own PI.
5. The developer's residual exposure to third parties (buyers, tenants, funders) is typically addressed via warranty and contract rather than PI.

BSA 2022 s.135 implications

1. BSA 2022 extended limitation for higher-risk-building work to 30 years pre-June 2022 and 15 years going forward.
2. Developers of higher-risk buildings face long-tail exposure to funders, buyers and tenants.
3. Where the developer provided professional-services-like input, PI-adjacent claims may follow.
4. Standard developer insurance may not respond to advisory-error claims — specific cover consideration needed.

Types of cover developers typically hold

1. Contract works insurance during construction.
2. Public liability for construction sites and completed premises.
3. Employer's liability for site workers if directly employed.
4. Latent defects insurance for building performance.
5. Professional indemnity where the developer provides professional services.
6. Directors' and officers' for company-level exposure.
7. Legal expenses for representation.

When developers need PI cover

1. Development consultancy services beyond pure development activity.
2. Project management for third-party developers as a fee-earning service.
3. Consultancy on planning, viability, sustainability to other developers.
4. Where the developer acts as its own designer without hiring qualified professionals.
5. Non-development activities like property management, valuation, tax advice provided as adjunct services.

Cover-sizing

1. Development-only firm without professional-services activity — PI often not needed.
2. Firm providing project management to third parties — £2m-£10m depending on project scale.
3. Development-consultancy firm — £5m-£25m.
4. Multi-activity firm (dev + PM + consulting) — layered programmes.
5. Sizing reflects specific professional-services scope, not overall development scale.
