One person may spend only a few hundred pounds finding out whether a public body’s decision can realistically be challenged. Another may need detailed advice, urgent drafting and representation, with legal costs rising into several thousand pounds before the court has even decided whether the case can proceed. Both situations fall under the same label: legal guidance on judicial review.
There is no standard price for this work in England and Wales. Private lawyers charge by agreement or by the hour, and the amount of time needed can vary sharply. A straightforward assessment of documents is a different job from preparing grounds of challenge, dealing with a public authority and appearing at a hearing.
For 2026, indicative hourly rates range from £142 to £295 outside London and from £210 to £579 in London, depending on seniority. Those figures give a sense of the market, but they do not tell you what your own case will cost. A junior lawyer working for several hours may charge less than a senior specialist working briefly on a difficult point, while a complex case can require input from more than one lawyer.
The first useful question is therefore not simply, “What is the hourly rate?” It is, “What work needs to be done?”
What private legal advice may include
An initial consultation usually focuses on the decision being challenged, the identity of the public body, the documents available and the result the claimant wants. The lawyer may need to consider whether the issue is suitable for judicial review rather than another legal route, whether the challenge is legally arguable and whether the available evidence supports it.
That assessment can be relatively limited. Someone might ask a solicitor to review a decision letter and explain whether there appears to be a viable public-law issue. In other cases, the lawyer may need to examine a lengthy file, correspondence, policies, meeting records and procedural history. The time involved can increase quickly when the facts are disputed or the decision has affected several people.
Advice may also cover the grounds of challenge. Judicial review is generally concerned with the lawfulness of a public decision-making process, rather than offering the court a general opportunity to substitute its preferred decision. A lawyer may therefore analyse issues such as whether the decision-maker acted within legal powers, followed a fair process or took account of relevant matters. The precise argument depends on the facts, and a weak disagreement with the outcome is not automatically a judicial review case.
If the case appears arguable, further work may include preparing a pre-action letter, organising evidence, drafting the claim and advising on the likely remedy. The lawyer may also explain the risks of losing and the possibility of being ordered to pay some of the other side’s costs. Those conversations are part of the advice, not an optional extra: a legal argument can be attractive in principle while still carrying financial risks that make litigation unsuitable for a particular claimant.
Some firms offer a fixed fee for a defined piece of work, such as an initial merits assessment or a pre-action letter. Others use hourly billing throughout. A fixed fee can make budgeting easier, but it should be clear what it covers. A fee for reviewing papers may not include further correspondence, urgent amendments, negotiations or attendance at a hearing. Before instructing a lawyer, it is sensible to ask for the scope of work, the estimated hours, the applicable rate and whether VAT or expenses are additional.
The court charges its own fees, separate from the lawyer’s bill. An application for judicial review costs £174 to file. If permission to proceed is granted, there is usually a further fee of £874. When permission is refused on the papers and an oral reconsideration is needed, the fee is £438. If permission is then granted after the oral hearing, a further £436 is payable.
These amounts can make an early cost estimate look deceptively simple. A person may focus on the first £174 and overlook the professional time needed to prepare the application or the later court fee if the case moves forward. The reverse can happen too: someone may assume that a high hourly rate automatically means an unaffordable case, without checking whether a lawyer can provide a narrow, one-off assessment rather than full representation.
A useful way to think about the bill is like a taxi meter that starts before the journey reaches the main road. Reading the papers, identifying the legal issue and explaining the risks may take place before any formal application is filed. Court proceedings then add their own charges and deadlines.
The amount of guidance required also depends on the claimant’s circumstances. A person with a well-organised file and a clear decision letter may need less preliminary work than someone whose documents are scattered across months of emails. A case involving an urgent decision, several agencies or a large factual record may require rapid review and repeated updates. Legal advice is often cheapest when the problem is defined early, although that does not mean every claimant should rush into proceedings without proper assessment.
Legal aid, court-fee help and the 2026 changes
Public funding may be available in some judicial review cases, but eligibility and the scope of funding matter. From 23 June 2026, new civil legal aid cases receive standard emergency representation for eight weeks, subject to a cost limit of £2,250. That temporary cover is designed to provide an initial period of assistance; it should not be confused with an unlimited promise to fund the entire case.
The limit means that a funded lawyer still has to manage the available work carefully. The initial period may be used to assess the case, take urgent steps and decide whether further funding is justified. A claimant should ask what the emergency representation covers, what happens when the eight weeks end and whether the cost limit includes all work or only specified tasks.
Financial eligibility is not the only consideration. Legal aid also depends on the type of case and whether it meets the relevant merits requirements. A person can have a low income but still be unable to obtain funding for a particular dispute, while someone with a potentially strong case may need to provide detailed financial information before support is confirmed.
Court fees are a separate issue. A claimant who cannot afford the filing or permission fees may be able to apply for a reduction or exemption through Help with Fees. The indicative monthly income limits are £1,420 for a single person and £2,130 for a couple. Savings are usually expected to be no more than £4,250, although the assessment depends on the individual circumstances and the relevant rules.
Those figures should be treated as a starting point rather than an automatic entitlement. Income, savings and household circumstances may all be examined, and the application must be completed accurately. Fee assistance may reduce the amount paid to the court, but it does not by itself pay a private solicitor’s hourly charges.
Where full legal aid is unavailable, a claimant can ask a firm about a limited retainer. That might involve paying for an initial review, a written opinion or assistance with one procedural stage while handling some communication personally. Not every lawyer will offer this arrangement, and it must be agreed clearly. A claimant should know whether the lawyer will merely advise, draft documents, communicate with the other side or take responsibility for filing the claim.
It is also worth separating legal guidance from representation. Advice about prospects and procedure may be enough for someone who can manage documents and correspondence. Representation becomes more expensive because the lawyer must prepare for hearings, respond to developments and speak for the claimant in court. A case that begins with a modest consultation can therefore become much more costly if it progresses.
The safest estimate comes from asking for two figures: the cost of the immediate task and the likely cost of the next stage if the case advances. That approach does not produce a single universal price, but it reveals where the money is going: professional time, court fees, urgent work and the level of representation required.
