Enduring Powers of Attorney are valid until your lifetime. It ceases upon the date of your death in which case your Will would take effect.
You can revoke your Enduring Powers of Attorney at any time whilst you have capacity. However, it is recommended that new ones are prepared to replace your existing ones.
If you become incapacitated without an enduring power of attorney, your family will have to apply to the Court to be appointed welfare guardians under the Protection of Personal and Property Rights Act 1988 - a process that can be costly, complex, and time consuming.
