Providers of Insurance for tools?

TangledMemories_2

Hi

I have a question.
My partner is a fully-fledged mechanic and has over £3k's worth of tools in order to do his job which he has purchased himself over the years.
We are trying to get insurance to cover his tools as his employers have since disclosed to staff that in the event of a break-in, their tools are not covered under their insurance.

I was wondering if anyone could point us in the right direction for some insurance to cover his tools? Obviously if anything were to happen, we couldn't afford to replace them.

Thanks

Tang
