Gifting money

I have just gifted a sum to my GD and her partner as a house deposit.
I had to state it was a gift not a loan, I had to prove
where the money came from , money laundering precautions and prove my identity.
As this was all done through solicitors it was free of course. You may have to pay a small sum but worth it to have everything recorded.
I had to actually pay the money to the solicitors.

As I understand it is free from inheritance tax as long as you survive for 7 years, similar to other financial gifts over the allowable amounts.
