The quickest way to get power of attorney in the UK depends on the type of power of attorney you need and the urgency of your situation. Generally, an Ordinary Power of Attorney (OPA) can be arranged more quickly than a Lasting Power of Attorney (LPA) because it does not require registration with the Office of the Public Guardian (OPG). However, OPAs are only valid while you still have mental capacity and are typically used for temporary matters such as hospital stays or short-term absence. For longer-term or more comprehensive authority, an LPA is recommended, though it takes longer to set up due to the mandatory registration process, which usually takes 8 to 10 weeks if there are no errors.
What Is Power of Attorney?
Power of attorney is a legal document that allows you (the donor) to appoint someone else (the attorney) to make decisions on your behalf. This can be essential if you become unable to manage your affairs due to illness, absence, or loss of mental capacity. In the UK, there are mainly two types:
- Ordinary Power of Attorney (OPA): A temporary arrangement for financial decisions, valid only while the donor has mental capacity. It is useful for short-term needs like hospitalisation or travel.
- Lasting Power of Attorney (LPA): A more comprehensive and longer-lasting authority that can cover financial/property decisions and health/welfare decisions. LPAs remain valid even if the donor loses mental capacity, but they must be registered with the OPG before they can be used.
Why Is Ordinary Power of Attorney the Quickest Option?
If you need power of attorney quickly, an Ordinary Power of Attorney is generally the fastest to set up because it does not require registration with the OPG. You can create an OPA by drafting a document with the correct wording granting specific powers to your chosen attorney. This can often be done with the help of a solicitor or local advice centre and can be effective immediately once signed by all parties.
However, OPAs have limitations: they become invalid if the donor loses mental capacity, and they are usually tailored for specific, temporary situations. Because there is no central registration, the process can be completed in days rather than weeks, making it ideal for urgent but short-term needs.
The Process and Timeline for Lasting Power of Attorney
For longer-term protection, a Lasting Power of Attorney is the better option, but it takes more time to set up. The process involves:
- Choosing the type(s) of LPA: You can create an LPA for property and financial affairs, health and welfare, or both.
- Completing the official forms: These must follow a specific format and include details of your chosen attorney(s).
- Signing and witnessing: The donor, attorney(s), and witnesses must sign the documents in the correct order.
- Registering with the Office of the Public Guardian (OPG): This is mandatory before the LPA can be used. Registration takes about 8 to 10 weeks if the application is complete and free from errors.
The property and financial affairs LPA can be used as soon as it is registered with the donor’s consent, even if they still have mental capacity. The health and welfare LPA only comes into effect if the donor loses mental capacity.
Can You Speed Up the LPA Process?
While the OPG’s registration process usually takes several weeks, you can ensure a smoother and quicker application by:
- Filling out forms accurately and completely to avoid delays.
- Providing all required supporting documents.
- Using professional help from solicitors or specialised advice services.
- Paying the application fee promptly (currently £82, with possible reductions or exemptions).
Unfortunately, there is no official fast-track service for LPA registration, so planning ahead is crucial if you anticipate needing one.

When Might You Need Power of Attorney Quickly?
Situations that may require rapid establishment of power of attorney include:
- Upcoming hospital stays or medical treatments.
- Temporary absence abroad.
- Sudden illness or injury affecting your ability to manage finances.
In these cases, an Ordinary Power of Attorney can provide immediate, though limited, authority. For long-term planning, setting up an LPA as early as possible is advisable to avoid complications if mental capacity is lost.
The quickest way to get power of attorney in the UK is usually by setting up an Ordinary Power of Attorney, which can be arranged quickly without registration but only lasts while you have mental capacity. For more durable and comprehensive authority, a Lasting Power of Attorney is recommended, though it requires registration with the Office of the Public Guardian and takes around 8 to 10 weeks to become effective. To avoid delays, it’s best to start the LPA process early, ensure forms are correctly completed, and seek professional advice if needed. This approach provides peace of mind that your affairs will be managed according to your wishes, even if you become unable to make decisions yourself.
