Real-Time UK Banking Data
Merchant identification and categorisation at 95%+ accuracy.
Financial data providers come from two different markets, which makes choosing between the top financial data providers harder than it looks.
Market data providers supply securities prices, company data and research to banks, asset managers and traders. Bloomberg and LSEG’s Refinitiv belong here.
This article covers banking and transaction data, the consented route UK platforms use to reach UK financial data through Open Banking. If you need market feeds, leave this shortlist. If you need consented account, balance and transaction data for software or financial workflows, keep reading.
UK Open Banking has reached scale. In June 2026, it recorded 40.16 million payments and 2.81 billion API calls, according to Open Banking Limited. The question is now: “How useful is the data?”
TL;DR: The top financial data providers are not interchangeable. TrueLayer, Yapily, Tink, Plaid, Salt Edge and Moneyhub differ in geography, licensing, scope and enrichment.
Finexer is a UK-focused option for platforms that need real-time banking data with merchant identification and categorisation. The buying question is not just bank count. It is data quality, consent and commercial fit.
How we built this shortlist of financial data providers
This comparison uses current public provider information and Finexer’s documented scope, and focuses on authorisation, coverage, freshness, consent and enrichment.
Identify the category before comparing providers
Financial data providers fall into four practical categories.
| Category | Supplies | Typical buyers |
|---|---|---|
| Market data | Prices, reference data, company and economic information | Banks, brokers, asset managers |
| Banking and transaction data | Account, balance and transaction data through Open Banking | SaaS, fintech, financial platforms |
| Credit reference agencies | Credit histories, scores and reference information | Lenders and risk teams |
| Enrichment specialists | Merchant names, categories and transaction intelligence | Accounting and analytics platforms |
Credit reference agencies appear only to prevent category confusion.
A market data terminal and an account information services (AIS) API can both rank for “financial data providers” while solving unrelated problems.
Know what banking data providers actually deliver
In UK Open Banking, an AIS provider gives an application access to customer-authorised account information after bank authentication.
The core dataset contains account, balance and transaction data. Payment initiation services (PIS) are separate: they initiate payments rather than reading data.
A buyer should test six criteria:
● Authorisation: Who provides the regulated AIS service?
● Coverage: Which account types are supported?
● Freshness: How quickly does new transaction information arrive?
● Consent: How are authorisation and reconfirmation handled?
● Enrichment: Can the provider identify merchants and categories?
● Connection model: Does the provider connect directly to each bank or through an intermediary?
Compare financial data providers in the UK
The table draws on each provider’s public documentation, including the firm reference numbers they publish.
| Provider | Data | UK authorisation | Coverage | Enrichment |
|---|---|---|---|---|
| Finexer | Account, balance and transaction data | FCA-authorised for account information and payment initiation (FRN 925695) | UK | Merchant identification and categorisation |
| TrueLayer | Account data and payments | FCA-authorised payment institution (FRN 901096) | UK and Europe | Data enrichment |
| Yapily | Accounts, balances and transactions | FCA-authorised for account information and payment initiation (FRN 827001) | UK and Europe | Categorisation through Data Plus |
| Tink | Transactions and account checks | FCA-authorised payment institution (FRN 988456) | Europe and UK | Enrichment and categorisation |
| Plaid | Transactions, balances and identity | FCA-authorised under the Payment Services Regulations 2017 (FRN 804718) | US, Canada, UK and Europe | Categories and merchant names in Transactions |
| Salt Edge | Account data | FCA-registered account information service provider (FRN 822499) | 5,000+ banks in 50+ countries | Categorisation and merchant identification |
| Moneyhub | Open Banking and Open Finance data, including pensions | FCA-authorised for account information and payment initiation (FRN 809360) | UK | Categorisation and enrichment engine |
Pan-European providers suit products where geographic breadth matters. UK-focused platforms may care more about local coverage, consent and transaction quality.
Our ranking of open banking solution providers compares several of the same firms on payments and verification, so this table stays on data access, authorisation and enrichment.
Treat data quality as the real differentiator
Coverage is a threshold question. The harder one is what your application can do with each transaction.
A bank description can be accurate for bank systems yet awkward for accounting software, property workflows or analytics. Merchant identification turns that description into structured information.
This is where top financial data providers can distinguish themselves. Better categorisation can reduce manual review.
Where enrichment specialists fit
Enrichment specialists sit alongside financial data providers, and some platforms buy enrichment as a separate layer. Our comparison of data enrichment tools shows how standalone tools differ from enrichment that ships with the data feed.
Finexer’s enrichment layer adds merchant identification and transaction categorisation, and our data enrichment api guide explains how UK platforms add both to their transaction feeds.
Do not assess enrichment from a feature list alone. Test recurring merchants, transfers, direct debits, standing orders and ambiguous descriptors.
Why Finexer belongs among financial data providers
If your brief starts with UK banking data and ends with transaction intelligence, Finexer warrants evaluation.
Finexer is infrastructure and not software. Platforms integrate its API into their own products. Its Data product provides consent-based AIS access to account, balance and transaction data.
Finexer’s banking data API provides the banking-data layer, while enrichment adds merchant identification and transaction categorisation.
Key buyer facts:
● 95%+ categorisation accuracy.
● Sub-100ms enrichment response.
● 100M+ merchants.
● Covers almost all major UK financial institutions.
● Direct one-to-one bank connection, with multiple data pulls/refreshes.
● FCA-authorised, FRN 925695.
The enrichment figures apply to enrichment and not AIS.
Match the provider to the platform
Accounting and ERP
Accounting platforms need transaction data that fits reconciliation workflows. Enrichment can add merchant and category context.
PropTech
Property platforms may need banking data for income-related workflows and rent processes. Test the account types and transaction fields your product needs.
WealthTech
Wealth platforms can use Finexer for account, balance and transaction data from supported bank accounts, such as cash position views and income tracking. Investment, pension and SIPP data is covered only where a bank exposes it through a supported Open Banking interface.
Utility billing
Utility and telecom platforms can use account and transaction data for billing workflows. Freshness and classification may matter more than an international institution count.
Advisory firms
Advisory firms also buy banking data. Advisers use consented account and transaction data to see a client’s income, spending and cash position before a review, and our article on financial advisory services shows how that fits advice workflows.
Ask for evidence before signing
A serious evaluation of financial data providers should end with evidence.
Request:
● Representative data from banks that your customers use.
● Consent and reconfirmation documentation.
● Account-type coverage.
● Refresh and historical-depth rules.
● Enrichment results for difficult cases.
● Connection model, and how often data can refresh.
● Regulatory responsibility.
Historical depth deserves attention. Finexer can retrieve up to seven years of history, depending on the connected bank.
“Up to X years” is therefore a weak standalone criterion. Ask what history you receive from the institutions that matter to your customers.
Match your need to a financial data provider
Start from the requirement that matters most when you compare financial data providers:
● Securities, prices or company research: a market data provider such as Bloomberg or LSEG.
● UK banking data with merchant identification and categorisation: Finexer, with a direct one-to-one bank connection.
● UK Open Finance data, including pensions: Moneyhub.
● Account data and payments across the UK and Europe: TrueLayer, Yapily or Tink.
● Account data across many countries: Salt Edge, which lists over 5,000 banks in 50+ countries.
● One provider for North America and the UK: Plaid.
The right provider is the one whose regulatory model, data scope, quality and commercial terms fit your product.
Who are the top financial data providers for UK banking data?
For consented UK account, balance and transaction data, the main options include Finexer, TrueLayer, Yapily, Tink, Plaid, Salt Edge and Moneyhub. They differ on authorisation, geographic focus and enrichment, so shortlist them against your customers’ banks and the transaction detail your product needs.
Do financial data providers need FCA authorisation?
Yes, for UK account information. A provider that accesses customer account data must be authorised or registered with the FCA, or act as an agent of a firm that is. Check the firm reference number on the FCA register and confirm which entity holds the permission you need.
Do banking data providers need customer consent?
Yes. For Open Banking account information, the customer authorises access and authenticates directly with their bank, so the provider never receives the bank password. Ask each provider how it captures consent, how long consent lasts and how reconfirmation works before your compliance review.
How should transaction enrichment be tested?
Use a representative sample of your own customers’ transactions, including recurring payments, transfers, direct debits, standing orders and ambiguous descriptors. Compare each provider’s merchant names and categories against records your team already considers correct, and track how many transactions still need manual review.
