Two-thirds of schools in England have poor fire protection systems and are not properly prepared for a potential blaze, according to an education insurer.

Zurich Municipal, which insures about half of all schools and universities in the UK, has written to the government calling for urgent action to improve fire protection in school premises after carrying out inspections at 1,000 sites over the past two years.

Zurich said 67% of English schools inspected were rated as having “poor” fire protection systems and 5% were awarded an “excellent” rating. In contrast, 29% of Scottish schools were rated as excellent.
