Capital Gains on (employer) share purchase shares

[thekingisdead]

I am hopefully selling a 2nd home shortly and will have some CGT payable.
I am also holding a number of shares in the company i work for that are currently sat at a loss. Thanks to Covid / Aerospace sector outlook looking dire I am thinking of realising the loss on the shares and using it to offset the property CGT.

Some of my share were purchased through a share bonus / share purchase scheme and held in trust.
Am i still able to use any losses on these shares to reduce a CGT liability?

Thanks,
