Just discovered my home not on UK Land Registry

Oh really ? If I were you, I would get it registered - makes it easier if you or your children, want to sell it.

Don’t worry, it’s normal for very old houses. My parents house built in early 1900’s wasn’t registered, it’s very easy to do it, all online as below

It's not a problem provided you have the original deeds. When you home is sold it will be registered as part of the process.

My daughter bought a house that wasn't on the land registry - It was just under three years ago I think.
The sellers had the deeds and like other sales it was just registered at point of sale.

To encourage people to register, HM Land Registry offers a 25% discount on their registration fees for voluntary applications.
I'd probably do it as that will protect you ftom a fraudulent claim.

I've just looked it up and solicitors tend to charge £500 to £1000 apparently.
The land registry fees currently are:
Up to £80,000 - £30
£80,001 to £100,000 - £70
£100,001 to £200,000 - £170
£200,001 to £500,000 - £250
£500,001 to £1,000,000 - £495
Over £1,000,000 - £830

Hope this helps.
