Can I offset old losses

I lost a lot of money on shares in 2008/2009 - around £80000. I am trying to sell a house and may be liable for some capital gains tax. Can I offset the losses from the shares ?

Hi,

If you had previously advised HMRC of these losses and they are on record, yes you can use them.
If you did not previously tell us, it is now to late as they must be notified within 4 years of them arising.

Thank you
