CILEX professional indemnity insurance — the complete UK guide 2026
~5 min readProfessional indemnity insurance for CILEX Fellows and CILEX-Regulated Entities covers the legal liability arising when legal work causes client loss. CILEX operates as an independent branch of the regulated legal profession under the Legal Services Act 2007. This guide sets out the two placement routes — SRA MTC coverage for CILEX Fellows in SRA firms, and standalone CILEX-compliant PI for CILEX-Regulated Entities.
CILEX regulates through CILEX Regulation. CILEX Fellows working in SRA firms are covered under the SRA MTC. CILEX-Regulated Entities operate under CILEX-specific PI rules. BSA 2022 s.135 30-year tail exposure applies to CILEX conveyancing firms same as SRA firms.
The regulatory framework for CILEX
The Chartered Institute of Legal Executives (CILEX) is a regulated profession under the Legal Services Act 2007. CILEX Regulation is the independent regulatory arm.
CILEX Fellow and CILEX Practitioner status
CILEX Fellows are Chartered Legal Executives with the right to hold themselves out as qualified lawyers. CILEX Practitioners are authorised for specific reserved activities (conveyancing, probate, litigation, advocacy). Different authorisations trigger different PI standards.
CILEX-Regulated Entities
Since 2015 CILEX-Regulated Entities can be authorised to operate as standalone legal practices without SRA authorisation. These entities must hold PI to CILEX-specified terms. Growing market segment.
Overlap with SRA
Most CILEX Fellows work in SRA-authorised firms. Their work is covered by the firm's SRA MTC PI. CILEX-only entities need standalone CILEX-compliant PI.
BSA 2022 s.135 exposure
CILEX firms doing residential conveyancing on higher-risk buildings face the same 30-year tail exposure as SRA firms under BSA 2022 s.135. Cover structure and run-off treatment must reflect this.
What CILEX PI insurance actually covers
CILEX PI covers legal liability from breach of duty in legal work performed by CILEX-authorised persons.
- Conveyancing errors in title, searches, or completion.
- Litigation deadline failures.
- Family law procedural errors.
- Probate work errors.
- Advocacy errors for advocacy-authorised Fellows.
- Defence costs for civil claims and CILEX Regulation disciplinary matters.
What claims typically look like
Claims patterns for CILEX firms tend to cluster around a small number of scenarios. Each has its own defence and reserve profile. The list below is illustrative of the types insurers actively track for pricing and appetite decisions.
Choosing the right cover limit
Cover limit selection is the single biggest structural decision in a PI placement. Under-cover means an aggregation event exhausts limit before defence costs are paid. Over-cover wastes premium on a limit no realistic claim would reach. The bands below reflect how experienced professional insurers think about limit selection for CILEX firms.
Run-off cover and long-tail exposure
CILEX-work claim tails follow the practice area — conveyancing six years, litigation six years, family longer where children's outcomes remain live. Six-year run-off standard; extended cover for deed-executed work.
How insurers rate this class
Insurers segment CILEX firms by practice area.
- General practice CILEX entities — broad appetite. Rate 1.5% to 2.5%.
- Conveyancing-heavy CILEX firms — higher rating. Rate 2% to 3.5%. BSA 2022 s.135 exposure for residential conveyancing.
- CILEX Fellows in SRA firms — PI under SRA MTC. No separate placement.
- Advocacy-authorised CILEX Fellows — specialist wording covering advocacy work.
