ARCHITECTS INSURANCE
SCHEME
AIS is a tailored PI insurance scheme developed by architects, for architects. Backed by expert brokers and managers and designed for modern architectural practices.


*Our primary offer is placed via Rokstone Underwriting, with A- rated (AM Best) capacity from Accredited Insurance (Europe) Limited. Depending on your specific needs, you may be offered terms from an alternative insurer.


The problem with traditional PI insurance
You already know PI cover is essential, but you’ve told us it’s holding your practice back. Since 2017, premiums have soared, exclusions have multiplied, and claims handling can feel like a black hole.
AIS has been created with those challenges in mind and with a clear vision for how a better and more stable future can be provided.
The scheme aims to provide:
- Stable, transparent pricing
- Enhanced cover that meets industry expectations
- An open and collaborative claims process, and ultimately
- A mutual model where members have a say.
What AIS offers
Your PI cover protects your business against legal costs and claims by third parties for damages arising from acts, omissions or breaches of professional duty in the course of your business.
Robust Cover Limits
