What is the best way to advertise a law firm in the UK?

There is no single best way, and any page naming one is guessing. The channel is set by how soon you need matters and what a click costs where you practise: a London immigration click cost £18.75 on 3 August 2026. One rule is fixed — never buy advertising priced per enquiry.

Why will nobody give you a straight answer to this?

Because the honest answer is a rule rather than a name, and a rule is harder to sell.

Of 40 legal-marketing suppliers we read in full on 3 August 2026, 8 claimed a guarantee of some kind and 17 of about 20 competitor calls to action we counted were a variation of the same free session. Both are symptoms of the same thing: a supplier selling one channel has to argue that channel is the answer, whatever the firm in front of them needs.

We sell websites and search work, so treat this page's preferences with the same suspicion. Where paid search is the right answer, we say so and lose the work, because we do not manage ad spend.

What actually decides the channel?

Your constraint, not the channel's merits.

Read the last row before the others. A firm whose enquiries already go unanswered will make its position worse by advertising, and no supplier makes money by saying so.

What is off the table in England and Wales?

Paying a price for each enquiry, in prescribed legal business.

LASPO 2012 section 56 prohibits referral fees in prescribed legal business, which includes personal injury, and it binds both the payer and the payee. That is the part usually missed. A firm buying injury enquiries at a price each is not merely dealing with somebody else's problem; it is inside the arrangement.

This is worth raising in the first meeting with any supplier, because a proposal priced by the enquiry tells you two things at once. It tells you what the commercial model is, and it tells you whether the supplier has read the rules that govern the reader they are pitching to.

Everything we do is priced by scope and time, published, and never by outcome or volume. That is a commercial choice as much as a cautious one: a supplier paid per enquiry is paid to send volume, and a firm wants the right enquiries rather than more of them.

Does the answer change between practice areas?

Sharply, and inside the same town.

Measured 3 August 2026. One hundred injury clicks bought at that price is £7,653; a hundred family clicks is £1,718. That is arithmetic on two measured figures, not a forecast of anything.

The consequence is concrete. In the injury column, paid search is expensive enough that a firm will usually want the slower channel working underneath it, and it is also the column where s.56 applies. In the family and conveyancing columns there is far more demand at a quarter of the price, so buying a test is cheap and there is little excuse for guessing. A national percentage of turnover cannot produce that answer. Your own two columns can.

What does the publication rule add here?

It makes some of the advertising work compulsory anyway.

The SRA Transparency Rules have been in force since 6 December 2018 and require price and service information for specified work types — the basis of charges, likely disbursements, indicative timescales, the qualifications and experience of those doing the work, and complaints information. Separately, 15 of the 62 questions buyers ask on these searches are price questions.

So the firm is expected to publish, on its own site, the answer to the thing most people want to know before ringing. Those pages are the cheapest advertising available to a UK firm and most treat them as an administrative task. Whether a particular service falls in scope is a matter for the firm and its COLP; we build the pages and assess nobody's obligations.

Where should I read next?

For the channels themselves rather than the choice between them: digital marketing for a lawyer and content marketing for a law firm.

If the site is what needs the work: solicitor website design and SEO for law firm websites.

For the practice area where s.56 bites: personal injury law firm marketing.

Whether the slow channel does anything at all: does SEO work for law firms.

The short answer is above. If you want the numbers behind it — demand in your town, what your site is missing, and what 40 suppliers charge — the report is free and takes about two minutes to request: /legal/uk/
