There are more than 25,000 organisations regulated by the Solicitors Regulation Authority (SRA) across England and Wales, and it is tempting to treat them as one audience. In reality, a firm in Cardiff and a firm in the City of London are rarely chasing the same work, and a marketer who treats “solicitors” as a single segment is leaving results on the table. We have spent time working through thousands of individual law firm records, cross-checking each one against its official website, Companies House filings and the SRA’s own published register of regulated firms, to build a clearer picture of what different parts of the country actually specialise in. The findings were more pronounced than we expected.
This piece sets out what that research shows, region by region and specialism by specialism, and what it means if you are planning a campaign aimed at the legal sector.
Why Treating Solicitors as One Audience Is a Mistake
Most B2B data lists segment solicitors by firm size, job title or postcode. That is useful, but it misses the more important question for most suppliers to the legal sector: what does this firm actually do? A firm of conveyancing solicitors in a market town has almost nothing in common, commercially, with a City firm doing regulatory and intellectual property work, even if both sit under the same SIC code. Selling into the wrong specialism wastes budget and, worse, damages the credibility of future approaches to the same firm.
Our own analysis, built by manually verifying practice area information against each firm’s own website and public filings rather than relying on a single generic category, backs this up. Once you sort firms by what they say about themselves, clear regional patterns appear that a postcode filter alone would never show you.

The National Picture: What UK Solicitors Actually Do
Across the firms in our research where a specialism could be confirmed, the most commonly cited practice areas nationally were:
| Practice Area | Share of Firms Citing It |
| Commercial, Corporate & Business Law | 47% |
| Family Law | 46% |
| Wills, Probate & Private Client | 41% |
| Litigation & Dispute Resolution | 38% |
| Conveyancing & Residential Property | 35% |
| Employment Law | 24% |
| Commercial Property | 21% |
| Criminal Law | 18% |
| Personal Injury | 18% |
| Immigration | 17% |
Firms very often cite more than one specialism, which is exactly what you would expect from general high street practices offering a broad service. The interesting story, though, is not the national average. It is how far individual regions move away from it.
Immigration Work Is Heavily Concentrated in London
Of the firms in our sample based in Greater London, close to a third cite immigration as a practice area, roughly double the national rate. This is not a huge surprise given London’s role as the country’s main point of entry and its concentration of international business, but the scale of the gap is striking. If you supply anything to immigration specialists, from translation and interpreting services to case management software or barrister referral networks, London is disproportionately where your buyers are, far more than population or firm count alone would suggest.
Personal Injury Specialists Cluster in the North West
The pattern reverses for personal injury. Firms in the North West cite personal injury as a specialism at roughly double the national rate, with Yorkshire and the Humber and the North East also running well ahead of the national average. London, by contrast, is noticeably light on personal injury work relative to its size. This lines up with what many people in claims management, medical reporting and rehabilitation services already sense anecdotally, our data simply puts numbers against it. If your product or service touches the personal injury claims process, a campaign weighted toward the North West and Yorkshire is likely to outperform one spread evenly across the country.
Conveyancing Runs Deepest in Wales and the North East
Well over half of the firms we identified in Wales and the North East cite conveyancing or residential property work, against just over a third nationally. London sits well below the national average on this measure, at roughly one in five firms, which fits with a City-heavy, commercial-weighted legal market rather than one built on residential transactions. For estate agency partners, search providers, surveyors and removal firms, Wales and the North East represent a noticeably denser concentration of conveyancing solicitors than a simple regional headcount would suggest.
Niche Specialisms Have Their Own Geography Too
The regional skew is not limited to the big practice areas. Agricultural law, for example, is roughly three times more common among firms in the East Midlands and the North East than the national average, with the South West and Wales also well represented, entirely consistent with where farming and rural land ownership are concentrated. Intellectual property, data protection, regulatory work, human rights and charity law all cluster heavily in London, at roughly one and a half to two times the national rate, reflecting its role as the base for the professional and financial services sector. Clinical and medical negligence work, by contrast, is notably under-represented in London and over-represented in the North West, South West and Yorkshire.
None of this is guesswork. It comes from checking what each firm actually says about its own services, then mapping that against where the firm is based.
What This Means for Your Next Campaign
If you are marketing to solicitors, the practical takeaway is simple. A list filtered only by job title, firm size or a broad regional split will still put your message in front of a lot of people it was never meant for. Layering practice area on top of geography lets you put a personal injury message in front of the North West and Yorkshire, an immigration message in front of London, and a conveyancing message in front of Wales and the North East, rather than sending one generic message to everyone and hoping some of it lands. We hold and continue to build practice area verified records for UK solicitors and law firms, segmented by both specialism and region.
Putting Regional Specialism Data to Work
The data gathered for this analysis points to something that experienced legal sector marketers often know instinctively but rarely have the numbers to prove: where a firm is based tells you something useful, but what it does tells you far more. A campaign built on geographic coverage alone is a blunt instrument. One built on the combination of practice area and region is something considerably sharper.
The patterns described above are consistent and pronounced enough to have real budget implications. Concentrating personal injury messaging on the North West and Yorkshire, immigration outreach on London, and conveyancing campaigns on Wales and the North East is not a minor refinement to a standard approach. For some suppliers, it could mean the difference between a campaign that generates pipeline and one that generates complaints from people who were never relevant prospects in the first place.
We continue to build and verify this data at a firm level, cross-checking each record against the SRA register, Companies House and each firm’s own published website rather than relying on a single data category. If you work with or sell to the legal sector and want to understand how practice area segmentation applies to your specific target market, the points below summarise where to start.

Based on our analysis, London has the highest concentration of firms citing immigration as a practice area, at roughly double the national average.
Personal injury work is most heavily concentrated among firms in the North West, with Yorkshire and the Humber and the North East also above the national average.
Yes. All Prospect360 business data is compiled and supplied in line with GDPR and PECR requirements for business to business marketing.
Our practice area classifications are checked against the Solicitors Regulation Authority’s own published register of over 25,000 regulated organisations across England and Wales, alongside each firm’s own website and public filings.
Across the firms in our research where a specialism could be confirmed, commercial, corporate and business law came out as the most frequently cited practice area, with close to half of all firms referencing it. Family law and wills, probate and private client work were the next most common, reflecting the volume of general high street practice that still makes up a significant portion of the UK legal market.
Wales and the North East both stand out, with well over half of firms in those regions citing conveyancing or residential property work, against just over a third nationally. London sits noticeably below the national average on this measure, which reflects the City’s commercial and corporate weighting rather than a market built around residential transactions.
Most firms, particularly those operating as general high street practices, cite more than one specialism. A firm may list family law, wills and probate and conveyancing alongside one another, serving the full range of needs for individuals and households in their local area. Larger and more commercially focused firms tend to run narrower, deeper practices in areas such as corporate law, intellectual property or regulatory work.
Agricultural law is roughly three times more common among firms in the East Midlands and the North East than the national average, with the South West and Wales also well represented. This distribution tracks closely with where farming, rural estates and agricultural land ownership are concentrated across England and Wales.
Beyond immigration, London firms are disproportionately represented in intellectual property, data protection, regulatory work, human rights and charity law, each running at roughly one and a half to two times the national rate. This reflects the capital’s role as the base for the financial services, professional services and corporate sectors, which drive demand for those practice areas.
Filtering by practice area lets you match your message to firms that actually do the work your product or service supports. A case management tool built for personal injury teams, a translation service for immigration practitioners, or a search provider working with conveyancers will each perform better when the list is filtered by specialism rather than sent to all solicitors regardless of what they do.
Each firm is checked against its own published website and Companies House filing, then cross-referenced against the Solicitors Regulation Authority’s register of regulated organisations. Where no reliable confirmation of a practice area can be found, that firm is excluded from the relevant figures rather than assigned a category based on assumption or SIC code alone.
Personal injury and conveyancing both sit noticeably below the national average among London firms. Clinical and medical negligence work is also under-represented in the capital relative to regions such as the North West, South West and Yorkshire. For suppliers in those areas, a London-heavy list is likely to underperform compared to one weighted toward the regions where those specialisms concentrate.
Yes. The records we hold allow for combined filtering, so you can identify, for example, personal injury firms in the North West, conveyancing practices in Wales, or immigration solicitors in Greater London. This combination of geography and practice area is where the real targeting value sits, rather than either filter used in isolation.
