uk alternative business structures: 15 years of performance data

the united kingdom provides the longest-running empirical evidence on alternative business structures in legal services. the legal services act 2007 introduced the abs framework, with first licenses granted in 2012. after 15+ years of development and 12+ years of operational experience, the uk offers crucial lessons for us regulators considering similar reforms.

executive summary

key metrics (as of 2024-2025):

• 1,000+ abs firms licensed, representing ~12% of all law firms in england and wales
• 33% of personal injury market controlled by abs firms by turnover
• 2-3x higher innovation rates compared to traditional firms
• £1.2 billion in private equity investment over five years
• major regulatory failures including axiom ince (£60m client fund shortage) and ssb law (£200m debts)

the data shows clear innovation advantages alongside significant consumer protection challenges and regulatory oversight failures.

market concentration by practice area

sra research from 2014 revealed significant abs market penetration:

the research showed “real diversity of firms with abs status” ranging from local to international operations, highlighting “the limitations of commenting on abss as a coherent and homogenous sub-segment of the legal services sector.”

innovation performance

abs firms demonstrate 2-3x higher innovation rates

research by the legal services board (lsb) and sra consistently shows abs firms lead in innovation:

new services introduction:

• 31% of abs firms introduced new services in last 12 months
• 13% of non-abs firms introduced new services
• 2.4x advantage for abs firms

new technology adoption:

• 53% of abs firms introduced new technology
• 33% of non-abs firms introduced new technology
• 1.6x advantage for abs firms

lsb research from july 2015 found “solicitors practising in newly created abs firms have higher levels of innovative activity of all types than other solicitors.”

access to underserved markets

sra research described abs as “bringing new resource to areas where there are barriers to access to justice for lower-income groups,” particularly in:

• mental health law
• social welfare law
• consumer claims

[source: legal futures]

capital investment benefits

research analyzing new uk abs firms found:

• “abs firm structure has provided access to capital to allow for investment in employee development and creative use of technology”
• “the abs form has brought some unregulated activities under the control of regulators”
• “created the possibility of linking legal services to other socially-conscious pro-consumer service providers”

genai adoption surge (2024)

the uk legal sector has seen rapid adoption of generative ai:

law firm adoption:

• almost 90% of top 100 law firms implemented or trialled genai tools (2024)
• up from only 55% in 2023
• one-third of firms believe at least 16% of existing chargeable work could be automated

weekly usage rates:

• 76% of legal professionals in corporate legal departments use genai at least once weekly
• 68% of law firm professionals use genai at least once weekly

major regulatory failures

axiom ince: £60 million client fund shortage (2023)

background:

• firm grew from 80 to 1,400 employees through 2021-2023 acquisitions
• revenue increased from £13.9m to over £107m
• collapsed with £60m ($64m) hole in client account

regulatory failures identified:

• sra flagged firm as high-risk “accumulator” months before collapse but failed to intervene effectively
• sra “did not act adequately, effectively and efficiently”
• failed to “take all the steps it could or should have taken”
• sra board not formally informed of intervention until weeks after client fund shortfall discovered

lsb enforcement action: lsb review found the sra’s oversight “severely dented” and imposed formal directions under section 32 of the legal services act 2007.

ssb law: £200 million in debts (2024)

background:

• sheffield-based firm handling thousands of civil litigation claims (mainly cavity wall insulation)
• placed into administration january 2024
• left debts of £200 million
• former clients facing heavy costs bills for unsuccessful claims

regulatory failures:

• over 100 complaints received by sra between january 2019 and march 2024
• complaints “ought to have raised alarm bells for the sra”
• sra ignored pattern over five-year period
• law gazette editorial: “ssb scandal is worse than axiom ince - this time, there’s no excuse”

government response: uk government announced it was stripping the sra of its ability to regulate aml (anti-money laundering) enforcement following the five-year period during which it ignored red flags.

slater and gordon uk: au$1 billion loss (2016)

background:

• australian firm became one of world’s first publicly-listed law firms (may 2007)
• entered uk market in 2012 with acquisition of russell jones & walker
• granted abs license april 30, 2012
• pursued aggressive acquisition strategy growing to uk’s 7th largest international law firm by revenue (2014)

collapse:

• trading suspended february 2016 after revealing losses of approximately au$1 billion
• december 2017: recapitalization via scheme of arrangement separated uk operations from australian operations

current status: uk operations now owned and operated separately as “one of the uk’s largest and most well-known consumer law firms.”

[source: wikipedia - slater & gordon, law gazette]

pattern of failures

other notable failures include:

• simpson millar/fairpoint: “expanded rapidly and suffered”
• parabis: “partnered with private equity, disappeared altogether, leaving creditors empty-handed”
• the aa legal: “effectively closed its legal business”
• saga legal: “foray was soon abandoned”

the pattern was clear: “the abs path was littered with those who flew too close to the sun.”

[source: law gazette]

common regulatory failures identified

systemic oversight weaknesses

1. heavy reliance on desk-based assessments rather than proactive investigation
2. missed clear signs of financial instability despite warning indicators
3. delayed board notification of serious concerns
4. inadequate oversight of “accumulator” firms undergoing rapid m&a expansion
5. failure to act on patterns of complaints over multi-year periods
6. client fund protection gaps for firms with external investors

law society president mark evans: “the report lays bare a lack of leadership and oversight of regulatory procedures at the sra.”

[source: law gazette]

required reforms (2025)

following axiom ince and ssb law failures, the lsb imposed formal directions requiring the sra to:

• comply with lsb directions within 12 months
• provide written progress reports every three months
• establish targeted, proactive oversight for “accumulator” firms
• improve early warning systems and complaint pattern analysis
• enhance board-level governance and transparency

[source: global legal post]

enhanced enforcement powers for abs

greater powers over abs vs traditional firms

the sra has significantly greater enforcement powers over abs firms compared to traditional law firms:

traditional firms (recognized bodies/sole practices):

• maximum sra fine: £25,000 for solicitors and firms
• higher fines require referral to independent solicitors disciplinary tribunal (sdt)

abs firms (licensed bodies):

• maximum sra fine for individuals: £50 million
• maximum sra fine for entities: £250 million
• no sdt referral required for these amounts
• section 99 orders available: disqualification from employment in legal sector

[source: sra financial penalties guidance, legal futures]

record enforcement action (2024)

the sra imposed its largest-ever fine of just under £4 million on the former non-solicitor owner of collapsed law firm kingly solicitors. as kingly was an abs, the sra could fine the individual up to £50m directly; had it been a traditional firm, the £25,000 limit would have applied.

private equity investment trends

£1.2 billion invested over five years

• over past five years: nearly £1.2 billion poured into uk law firms
• £534 million invested in 2024 alone (acquira estimate)
• private capital increasingly targeting boutique expertise in specific regions and specialisms:
  • family law
  • employment law
  • risk compliance and ip advice
  • personal injury and commercial litigation

[source: pinsent masons]

notable pe-backed transactions

lawfront group (backed by private equity investor blixt group):

• acquired east midlands-based nelsons solicitors (2023)
• acquired manchester-headquartered slater heelis (2024)

[source: pinsent masons]

current performance challenges

sra operational struggles

as of 2024-2025:

• reports about solicitors received by regulator rose by more than a quarter this year
• only 36% of initial assessments completed within two months (target: 80%)
• performance described as “severely dented” by both axiom ince and ssb reviews

[source: legal futures]

persistent access to justice gaps

despite abs growth and innovation, lsb estimates 3.6 million individuals have unmet legal needs annually in england and wales. this suggests abs alone has not solved the access-to-justice crisis, though it may have prevented further deterioration.

lessons for us regulators

positive lessons

1. innovation catalyst: abs structure demonstrably increases innovation rates (2-3x in some metrics)
2. capital access: enables investment in technology, training, and expansion
3. market penetration: can achieve significant market share in targeted sectors (33% of uk pi market)
4. underserved populations: brings resources to areas with access-to-justice barriers
5. professional regulation: brings previously unregulated activities under regulatory oversight

critical warnings

1. “accumulator” firm risk: rapid growth through m&a creates unique regulatory challenges requiring proactive oversight
2. regulatory capacity: standard desk-based assessment insufficient; requires dedicated resources and expertise
3. early warning systems: must act on patterns of complaints rather than waiting for crises
4. governance transparency: board-level visibility into high-risk firms essential
5. client fund protection: enhanced monitoring needed for firms with external investors/non-lawyer owners
6. enforcement powers: need adequate authority to intervene quickly when concerns arise

specific lessons from major failures

from axiom ince:

• monitor acquisition velocity as risk indicator
• require integration plans for m&a activity
• escalate oversight with each major acquisition
• don’t delay board notification of concerns

from ssb law:

• pattern of complaints = early warning signal
• investigate unusual business models
• don’t ignore red flags over multi-year periods
• client volume ≠ consumer protection success

from slater and gordon:

• public listing creates additional pressures
• cross-border operations complicate oversight
• revenue growth ≠ operational stability
• acquisition-driven growth highest risk category

recommendations for us jurisdictions

1. regulatory infrastructure first

• don’t liberalize faster than regulatory capacity: uk shows oversight failures persist even after 15 years
• invest in specialized expertise: traditional desk-based regulation insufficient for abs firms
• build real-time monitoring: can’t rely on annual reviews for fast-growing firms

2. targeted risk management

• identify “accumulator” firms early: rapid m&a growth requires heightened oversight
• create intervention thresholds: clear triggers for proactive regulatory action
• enhanced client fund oversight: non-lawyer ownership increases risk to client funds
• quarterly board reporting: high-risk firms need executive-level visibility

3. consumer protection mechanisms

• adequate compensation funds: uk failures left hundreds of millions in losses
• complaint pattern analysis: must act on trends, not wait for crises
• public disclosure requirements: market discipline requires transparency
• clear recourse mechanisms: consumers need accessible remedies

4. data collection and evaluation

• mandatory abs-specific reporting: can’t evaluate what you don’t measure
• consumer outcomes tracking: beyond firm counts, measure access improvements
• comparative analysis required: abs vs non-abs performance data
• regular independent evaluation: don’t rely solely on regulator self-assessment
• public transparency: published data enables academic and policy analysis

5. incremental implementation

• phased rollout: utah sandbox model allows learning before permanent adoption
• regular review points: arizona’s permanent approach should include scheduled evaluations
• cross-jurisdiction learning: share data and insights across us states
• international comparison: continue monitoring uk, australia, other jurisdictions
• reversibility planning: build in mechanisms to modify or reverse if problems emerge

lsb evaluation findings

the lsb’s evaluation of abs and investment in legal services (2011-2017) found:

positive but slow progress:

• “positive developments emerged but improved outcomes for consumers are emerging slowly”
• “the sector has grown substantially since 2007”
• “new business models permitted by the lsa have established significant market shares”
• “while levels of innovation have remained broadly the same, research suggests that abs are more innovative”

conclusion

the uk’s 15+ year experience with alternative business structures provides invaluable lessons for us regulators. the data shows:

clear benefits:

• demonstrable innovation advantage (2-3x in key metrics)
• significant market penetration in targeted sectors (33% of pi market)
• technology adoption leadership (particularly genai)
• new capital sources for underserved markets

serious challenges:

• major regulatory oversight failures (axiom ince, ssb law, slater and gordon)
• hundreds of millions in consumer losses
• high-profile firm collapses
• persistent unmet legal needs despite market growth
• regulatory capacity struggles even after 15 years

critical success factors: the uk experience suggests abs can succeed with:

1. adequate regulatory infrastructure scaled to market size
2. proactive risk-based oversight especially for high-growth firms
3. strong consumer protection mechanisms including compensation funds
4. clear professional standards that extend to non-lawyer participants
5. transparent data collection enabling continuous evaluation
6. political will to enforce including against large, influential firms

for us regulators: the uk provides both encouragement and caution. abs can drive innovation and potentially improve access, but only with robust regulatory frameworks that evolve with the market. states considering abs adoption should:

• move thoughtfully rather than rapidly
• invest in regulatory capacity before full liberalization
• require demonstration of access improvements
• learn from uk’s oversight failures
• maintain flexibility to adjust approach based on evidence

the uk’s journey is ongoing, not concluded. recent regulatory failures (2023-2024) and required reforms (2025) demonstrate that even mature abs markets require continuous regulatory evolution and vigilance.
