An ETA does not guarantee entry to the UK. You still need to either:
see a Border Force officer
use an ePassport gate
You may want to apply for a Standard Visitor visa instead if you have a criminal record or you were previously refused entry into the UK.
What you cannot do with an ETA
You cannot:
stay in the UK for longer than 6 months
do paid or unpaid work for a UK company or as a self-employed person, unless you are doing a permitted paid engagement or event or work on the Creative Worker visa concession
claim public funds (benefits)
live in the UK through frequent or successive visits
marry or register a civil partnership, or give notice of marriage or civil partnership - you need to apply for a Marriage Visitor visa
How much it costs
It costs £10 to apply using the UK ETA app or online through GOV.UK. Other websites may charge more.
From 9 April, it will cost £16 to apply for an ETA.
Everyone travelling needs to get an ETA, including babies and children. You can apply for other people.
