How Much Does Power of Attorney Cost in the UK? (2026)

The cost of power of attorney in the UK varies significantly depending on how you set it up. Many people assume they need a solicitor and are put off by the potential cost — but in reality, setting up a Lasting Power of Attorney (LPA) yourself with an online tool like Doxly costs a fraction of the solicitor route.

The OPG Registration Fee

The Office of the Public Guardian (OPG) charges £92 to register each LPA document. This fee goes to the government, not to any service provider. Since a Property & Financial Affairs LPA and a Health & Welfare LPA are two separate documents, you pay £92 for each — £184 in total if you register both.

This fee is set by the government and applies regardless of whether you use a solicitor, an online service, or the OPG's own tool. You cannot avoid it — it is a statutory charge for registration.

Do You Need to Pay a Solicitor?

No. Solicitor involvement is not a legal requirement for setting up a power of attorney in the UK. The OPG provides its own free online tool, and services like Doxly generate the forms for £4.99 with a significantly easier user experience.

A solicitor may add value if your situation is complex — for example, if you have business interests, overseas assets, or anticipate family disputes. For most people, however, a standard LPA generated online is perfectly adequate.

Why Do Solicitors Charge So Much for LPAs?

Solicitor fees for LPAs reflect their professional time, liability insurance, and the complexity of their regulatory obligations. A solicitor who helps you set up an LPA is also taking on professional responsibility for the document — which is why they charge accordingly. For straightforward LPAs between family members, this level of professional involvement is often unnecessary.

Can I Reduce the Cost of Power of Attorney?

• Use an online generator: Doxly generates your forms for £4.99 versus £300–£500 for a solicitor
• Check for fee remission: Low-income individuals may qualify for reduced or waived OPG registration fees
• Set up both LPAs at the same time: The process is almost identical, so doing both together saves significant time
• Use a GP as certificate provider: GPs often provide the certificate for free as part of their NHS role

What is the Total Cost of Getting Power of Attorney in the UK?

For most people using Doxly and registering both LPAs with the OPG, the total out-of-pocket cost is approximately £194 — £9.98 for both Doxly documents and £184 in OPG registration fees. Compare this to the solicitor route at £784–£1,184 for both LPAs.
