UK Online Broker Checklist: FCA, FSCS and Account Checks

UK broker searches are one of the strongest country signals in InvestorTrip's Google Search Console export, but a UK broker ranking should wait until each broker has verified UK availability, FCA permissions, product limits, fee rows and reviewer status. This page does not rank UK brokers. It gives UK residents and UK-focused investors a checklist for checking the firm, account wrapper, tax records, costs and scam risk before depositing.

Start with the exact firm

Do not start with a brand name alone. Record the legal entity in the account agreement, the firm reference number if one is supplied, the country of incorporation, whether the account is UK-regulated or offshore, and which entity receives client money.

A broker group can operate several entities. A UK website, UK phone number or UK marketing page does not prove that your account is opened with a UK-authorised firm. Ask for the exact legal entity and agreement before funding.

Check FCA authorisation and permissions

The FCA Firm Checker is designed to help consumers check whether a firm is authorised and has permission to provide the services being offered. The FCA Financial Services Register is the public record of firms, individuals and other bodies authorised by the FCA or PRA.

When checking a broker, match:

Legal name and trading names.
Firm reference number.
Current status.
Permissions relevant to the product.
Approved contact details and website.
Appointed representative relationships, if any.
Restrictions or warnings linked from FCA pages.

Use the FCA contact details, not phone numbers or links sent in an unsolicited message. The FCA warns that clone firms can copy the name, address and firm reference number of genuine authorised firms.

Understand FSCS and client-money limits

FSCS can protect eligible customers when authorised financial services firms fail, and its coverage includes investments, deposits, pensions and other regulated services. That does not mean every loss is covered. Investment losses, crypto losses, overseas entities, professional-client accounts, product failures and poor trading decisions can fall outside protection.

Before choosing a broker, check the current FSCS page and the broker's own client-money disclosure. Ask which legal entity holds the account and whether the relevant claim would be against a UK-authorised firm. If the account is opened with an offshore entity, UK FSCS assumptions may not apply.

Account wrapper and tax questions

UK investors often compare general investment accounts, Stocks and Shares ISAs, SIPPs and cash accounts as if they are interchangeable. They are not. The tax wrapper changes eligibility, contribution rules, withdrawal rules, investment range and reporting.

Before opening an account, verify:

Is this a general investment account, ISA, SIPP or another wrapper?
Are you eligible to open it as a UK resident?
What annual allowance or contribution limits apply?
Does the broker provide dividend, interest and disposal records?
Are non-UK withholding tax forms supported?
Are FX conversion records and contract notes downloadable?

GOV.UK explains that Capital Gains Tax applies to gains when an asset is disposed of, subject to allowances and exemptions, and that dividend income can be taxable above the dividend allowance while dividends inside an ISA are not taxed. This page is not tax advice; use official guidance or a qualified adviser for your own position.

Costs and platform checks

A low commission can be outweighed by platform charges, FX conversion, fund fees, withdrawal costs or bid-ask spreads. For each broker, collect current fee schedule evidence for:

Account or custody fee.
Share, ETF, fund and option dealing charges.
FX conversion spread or commission.
ISA, SIPP, drawdown or transfer fees where relevant.
Inactivity, data, withdrawal or paper statement fees.
Margin interest and product restrictions.
Order routing and execution policy.
Cash interest and uninvested cash treatment.

Save source URLs and snapshot dates. A credible UK broker ranking needs those rows before publication.

Red flags

Pause if:

The firm is not on the FCA Register or Firm Checker for the service offered.
The website uses a real firm's FRN but different contact details.
Deposits go to a third party, crypto wallet or personal account.
Support pressures you to become a professional client.
The broker promises guaranteed returns or tax-free trading.
Withdrawals require extra release, tax or clearance payments.
The account agreement names an offshore entity you did not expect.

Bottom line

For UK broker research, verify the FCA status, legal entity, FSCS position, account wrapper, fee schedule, tax records, funding route and clone-firm risk before comparing platforms. Until InvestorTrip has verified broker-by-broker UK rows, this checklist is safer than a UK broker ranking.
