The UK has a large market for outsourced research and specialist business work. Banks need credit and investment research. Law firms need document review and legal support. Consulting firms use outside research teams when projects move quickly, while companies in insurance, retail and manufacturing increasingly outsource data and analytics work.

This is where Knowledge Process Outsourcing, usually shortened to KPO, fits in.

KPO is not the same as moving routine customer service or data entry to an outside company. The work usually needs some understanding of finance, law, research, data, a particular industry or all of these together.

London naturally accounts for a large part of the demand. The city has banks, asset managers, private equity firms, insurers, consulting companies and law firms, and many KPO providers keep UK client teams there. The actual work may then be split between London and larger delivery centres in countries such as India.

This article covers 10 KPO companies in UK with operations or a meaningful client presence in the country. It is not a strict revenue ranking. Some are large outsourcing groups, while others work almost entirely in specialist areas such as investment research or legal services.

1. Genpact

Started	1997
UK Office	London
Original Business	GE Capital operations
Main Work	Finance, data, analytics and risk

Genpact started inside GE Capital in 1997. Its first work was much closer to business-process management than the data and AI work the company talks about today.

It became an independent company in 2005 and expanded into banking, insurance, manufacturing, consumer goods, healthcare and other industries.

Finance remains a large part of its business. Genpact works on accounting, financial planning, reporting, risk and compliance, but it also handles areas where the client needs more analysis than simple transaction processing.

Its data teams work on forecasting, customer analysis, risk models and other decisions built around large amounts of information.

The company has also been adding AI to these operations. In practice, this means some work that analysts once did manually can now be searched, grouped or checked by software before a person reviews the result.

Genpact’s size makes it different from many smaller KPO firms. A client can use the same provider for an analytical team as well as the larger business process around it.

Unique Offerings

• Finance and accounting
• Data and analytics
• Risk and compliance
• Supply-chain services
• AI-supported operations
• Industry-specific business services

2. WNS

Founded	1996
UK Origin	Started with British Airways
UK Office	London
Main Work	Analytics, finance, research and procurement

WNS has British roots.

The company began in 1996 as an internal operation for British Airways. It later started taking work from outside clients and developed into a much larger outsourcing company.

Travel is still part of its business, but WNS now works with banks, insurers, retailers, healthcare companies, utilities and other industries.

Research and analytics sit inside that wider operation.

A procurement team, for example, may use WNS to study suppliers, prices and market conditions instead of only asking the company to process purchase orders. Insurance clients can use its analysts for claims, pricing or other work that needs industry knowledge.

WNS also strengthened its research business by buying The Smart Cube, a company known for market and procurement intelligence.

The ownership changed in 2025 when Capgemini acquired WNS. The WNS business now sits inside the wider Capgemini group rather than operating as a separate listed company.

Unique Offerings

• Research and analytics
• Procurement intelligence
• Finance and accounting
• Insurance services
• Banking operations
• Customer analytics

Official website: WNS

3. EXL

Founded	1999
UK Presence Since	2004
UK Office	London
Main Work	Data, analytics and insurance

EXL started as an outsourcing business but has moved much more heavily into data and analytics.

The company opened its first UK office in 2004.

Insurance is one of the areas where its KPO work is easiest to see. EXL works with insurers on pricing, underwriting, claims analysis, actuarial work and risk.

These jobs need people who understand what the numbers represent.

A claims analyst is not only sorting information into a spreadsheet. An underwriting team has to think about the likelihood and cost of a future loss. Actuarial work goes further again and depends heavily on statistical modelling.

EXL also works with banks, healthcare businesses, utilities and retailers. Its teams analyse customers, operations, financial risks and other areas where companies already have a lot of data but still need help deciding what to do with it.

Unique Offerings

• Insurance analytics
• Actuarial support
• Customer analytics
• Risk analysis
• Data science
• AI and decision support

Official website: EXL

4. Infosys BPM

Established	2002
Parent Company	Infosys
UK Office	London
Main Work	Finance, analytics and legal services

Infosys BPM started in 2002 under the name Progeon.

It was later renamed Infosys BPO and then Infosys BPM as the company moved into a wider range of business services.

Some of that work is conventional outsourcing. Other parts are clearly knowledge-based.

The financial-services teams work on areas such as investment banking, asset management, financial planning, regulatory work, AML and KYC.

Its legal-services business is another example.

Infosys BPM provides legal research, contract support and compliance work. Legal research can involve checking legislation, court decisions or regulatory requirements across more than one jurisdiction.

That kind of work cannot be completed properly by following the same fixed steps every time.

The connection with Infosys also gives the BPM business access to technology, automation and data capabilities from the wider group.

Unique Offerings

• Financial-services support
• Legal research
• AML and KYC
• Contract services
• Finance and accounting
• Data analytics

Official website: Infosys BPM

5. Acuity Knowledge Partners

Headquarters	London
Specialists	6,000+
Clients	650+
Main Work	Financial research and analytics

Acuity Knowledge Partners is much more concentrated on financial services than most of the larger companies in this list.

The business is headquartered in London and works with investment banks, asset managers, private equity firms, commercial banks and consulting companies.

Its teams can support an investment from the early research stage through to monitoring after a deal has been completed.

That work may start with an industry study or a list of possible acquisition targets. It can then move into company analysis, valuation, financial modelling and due diligence.

Commercial banks use a different part of the business.

Their requirements include credit analysis, borrower reviews and monitoring existing loan portfolios.

Acuity also supports investment research across companies and industries. Analysts may follow financial results, update models and prepare information for investment teams.

This focus has kept the company close to what people traditionally mean when they talk about KPO.

Unique Offerings

• Investment research
• Financial modelling
• Private equity support
• Credit analysis
• Investment banking support
• Commercial lending research

Official website: Acuity Knowledge Partners

6. Evalueserve

Founded	2000
UK Presence	London
Professionals	5,000+
Main Work	Research, intelligence and analytics

Evalueserve started with research and analytics in 2000.

Those two areas are still central to the business.

Its researchers work on competitors, industries, customers, investments and regulations. A company considering a new market, for example, may need information on market size, prices, existing competitors and likely customers before deciding whether expansion makes sense.

The work does not always end with one report.

Some clients use Evalueserve for regular competitor tracking or market updates. That gives management teams a continuing source of information rather than forcing them to commission a new study every few months.

Evalueserve also works with banks and investment firms on credit and financial research.

Data tools now play a larger role in how the company collects and organises information, but analysts are still needed to decide which findings are useful and which ones are not.

Unique Offerings

• Market intelligence
• Competitor research
• Investment research
• Credit research
• Risk intelligence
• Data analytics

7. Integreon

UK Office	London
Main Market	Legal and professional services
Clients	Companies and law firms
Main Work	Legal and compliance support

Integreon is best known for legal outsourcing.

Its clients include corporate legal departments and law firms that need additional help with contracts, litigation, compliance and document work.

Contract review can become a major workload for a large business.

A company may have thousands of supplier, customer and employment contracts stored across different systems. If regulation changes or the business introduces a new contract policy, those documents may need to be checked again.

Integreon provides teams for this type of work.

It also handles document review for disputes and investigations. In a large case, the amount of material can run into thousands or even millions of documents.

Software can narrow that material down, but people still need to understand why a particular document may matter.

The company also provides research and other professional support alongside its legal services.

Unique Offerings

• Contract review
• Legal operations
• Document review
• Compliance support
• Litigation services
• Research support

Official website: Integreon

8. SG Analytics

Founded	2007
UK Office	London
Current Parent	Straive
Main Work	Research, data and analytics

SG Analytics started as an investment research company in 2007.

It still works in that area, although the business now covers much more.

Its financial teams support investment banks, asset managers, private equity firms and other financial companies with research, financial models and industry analysis.

Market research is another part of the company.

A client may want to understand how big a market is, who already sells into it or what customers think about an existing product. The work can involve published information, interviews and data analysis rather than depending on one source.

SG Analytics also works on ESG, data management and financial-crime compliance.

The company expanded its presence in London as it increased its work with British and European clients.

In 2025, Straive acquired SG Analytics. The business is now part of the larger Straive group.

Unique Offerings

• Investment research
• Market research
• Financial modelling
• Private equity support
• ESG research
• Compliance analytics

Official website: SG Analytics

9. TresVista

Founded	2006
UK Office	London
Main Clients	Investment firms and companies
Main Work	Financial and investment support

TresVista is another company built largely around financial work.

It started in 2006 and has since worked with private equity firms, asset managers, investment banks and corporate finance teams.

Financial modelling is an important part of that work.

Before making an investment, a fund may want to understand how much a company could earn under different assumptions. Analysts can build a model around revenue, costs, debt and other factors to see how the business may perform.

Research often sits beside the model.

The same project may need industry information, competitor data or a list of similar transactions before an investment team reaches a decision.

TresVista also supports portfolio monitoring after investments have been made.

Its CFO services cover another part of finance, including reporting, forecasting and financial planning for businesses that need extra capacity in the finance team.

Unique Offerings

• Financial modelling
• Investment research
• Valuation
• Due diligence
• Portfolio monitoring
• CFO support

Official website: TresVista

10. Infomineo

Founded	2011
Specialists	350+
Typical Clients	Consulting firms and companies
Main Work	Business research and market intelligence

Infomineo is smaller than Genpact, WNS or Infosys BPM, but research makes up a much larger share of what it does.

The company was started in 2011 by former consultants.

Consulting firms are still an important part of its client base.

A project team may suddenly need reliable information on a market it has never studied before. The question could be about competitors, factories, prices, distributors, regulations or the size of a particular industry.

Some answers are available in public databases. Others have to be pieced together from company filings, government sources, industry reports and local publications.

Infomineo provides research teams for that work.

The company has also added analytics and AI tools, partly because they can speed up the first stages of searching and organising information.

Researchers then check the material before it reaches the client.

That checking is important. A fast answer is of little value if the underlying information is wrong.

Unique Offerings

• Business research
• Market research
• Competitive intelligence
• Data analysis
• AI-supported research
• Research quality checks

Why the KPO Industry Matters in the UK

London Creates a Large Market for Financial Research

London remains one of the world’s major financial centres.

Banks, investment firms and private equity funds all produce a large amount of analytical work before money changes hands.

An investment firm does not simply look at a company’s current profit and decide whether to buy it.

It may study the wider industry, management, competitors, debt, possible growth and what similar businesses have sold for.

That takes time.

Companies such as Acuity Knowledge Partners, TresVista and SG Analytics provide extra analysts for this work.

The client still makes the investment decision. The KPO team helps collect and analyse the information behind it.

Legal Work Can Also Be Outsourced

Not every legal job has to stay inside a law firm’s office.

Some pieces of work can be separated from the main legal advice and handled by specialist outside teams.

Document review is one example.

During litigation or an investigation, lawyers may receive huge amounts of emails, contracts and other records. Reviewing all of them with only the firm’s permanent lawyers can become expensive very quickly.

Contract work creates the same problem on a more regular basis.

Integreon and Infosys BPM are among the companies that provide additional teams for these jobs.

The work still needs legal knowledge, but the client does not have to increase its permanent headcount every time volumes rise.

Companies Want Research More Often

Market research has also changed.

Businesses used to commission a large report and then work from it for months.

That is harder when competitors, prices and regulations can change quickly.

Many companies now want information updated continuously.

A manufacturer might track the price changes of five competitors every month. A consumer company may want regular information about new products in its category. A strategy team could follow regulatory changes in several countries.

This creates more ongoing work for companies such as Evalueserve and Infomineo.
