One of the most common questions people ask when planning ahead is how much does a UK power of attorney cost. The answer is usually reassuring. For most people, an LPA is far more affordable than expected and significantly cheaper than the alternatives if no planning is done.

What is a lasting power of attorney and why does cost matter?

A lasting power of attorney allows you to appoint someone you trust to make decisions on your behalf if you lose mental capacity. These decisions can relate to finances, property, health and care.

There are two separate LPAs. One covers Property and Financial Affairs and the other covers Health and Welfare. You can make one or both, depending on your needs.

Understanding the cost upfront helps people plan properly and avoids delays that can cause serious problems later.

What is the official cost of a UK lasting power of attorney?

The Office of the Public Guardian charges a fixed registration fee of £92 per LPA. This means the total government fee is £184 if you register both types.

Some people qualify for a reduction or full exemption. If your income is below £12,000 a year or you receive certain means tested benefits, you may pay less or nothing at all.

This fee is the same regardless of how you create your LPA.

Are there additional costs when setting up an LPA?

Additional costs depend on whether you use professional help. Completing the forms yourself through the government website is free, aside from the registration fee. However, mistakes can cause delays or rejection.

Solicitors often charge between £400 and £1,000 or more per LPA, particularly if your finances are complex.

Online services such as POA Online offer a middle option. They typically charge a lower fixed fee while providing guidance, form checks and support to reduce errors and stress.

Why do some LPAs cost more than others?

The cost often reflects the level of support provided. More complex family arrangements, business interests or tailored instructions can increase professional fees.

Location also matters, as solicitor costs vary across the UK. What does not change is the OPG registration fee, which applies to everyone equally.

Choosing the right route depends on your confidence with paperwork and how much reassurance you want.

What is the real cost of not having a lasting power of attorney?

If you lose capacity without an LPA, your family may need to apply to the Court of Protection to gain authority to act. This process can cost several thousand pounds, take many months and involve ongoing supervision fees.

More importantly, it often causes stress and delays at exactly the wrong time.

Compared to this, the cost of an LPA is a modest one off expense that prevents far greater financial and emotional strain.

Is a lasting power of attorney worth the cost?

For most people, yes. An LPA protects your wishes, reduces uncertainty and gives your loved ones legal authority when it matters most.

With affordable online options now widely available, cost should no longer be a barrier. A lasting power of attorney is not just a legal document. It is peace of mind at a sensible and predictable price.
