The Best Prop Firms in the UK for 2026, Compared

When do the main trading sessions line up on a UK clock?

The session times below assume a working day of 08:00 to 17:00 in each centre, which is a convenient assumption and not an official timetable. Each figure is plain arithmetic from standard UTC offsets.

London is the reference clock. Its session runs 08:00 to 17:00 UK time all year, because the convention is defined in London time and the UK moves between GMT (UTC+0) and BST (UTC+1).

New York is five hours behind London for most of the year, so its session runs about 13:00 to 22:00 UK time and overlaps London from about 13:00 to 17:00. The United States moves its clocks earlier in March and later in the autumn than the UK does, so for about four weeks a year the gap is four hours and the overlap widens to about 12:00 to 17:00.

Tokyo is the awkward one: its session runs about 23:00 to 08:00 UK time in winter and 00:00 to 09:00 in summer, so a UK trader who wants that session is working through the night.

Readers living outside the UK mainland clock should shift each time by their own difference.

What does the FCA's guidance on financial promotions say?

The Financial Conduct Authority's Handbook includes the perimeter guidance PERG 8, on financial promotion and related activities. PERG 8.2.1 summarises section 21 of the Financial Services and Markets Act 2000: an unauthorised person must not communicate an invitation or inducement to engage in investment activity, unless an exemption applies or an authorised person has approved it for the purposes of section 21.

PERG 8.3.1A adds that an authorised person is unable to approve the content of a communication unless it is a permitted approver or an approver permission exemption applies. PERG 8.2.3 says an authorised person does not breach section 21 when communicating a financial promotion of its own.

PERG 8.2.4 says a person who carries on activities in breach of section 21 commits a criminal offence under section 25, with a maximum of two years' imprisonment and an unlimited fine, and that it is a defence to show the person took all reasonable precautions and used all due diligence.

The part of PERG 8 read for this page does not mention prop firms or simulated evaluations, and this page cites no FCA statement about them. It gives no view on whether any firm's marketing is within these rules, and nothing here is legal advice.

How does HMRC's guidance describe the badges of trade?

HMRC's Business Income Manual page BIM20205 is the summary of the badges of trade, the indicators used to judge whether an activity is a trade. It says the courts decide questions of trade on the basis of the overall impression from reviewing all of the badges, and that the presence or absence of a particular badge is unlikely, by itself, to provide a conclusive answer.

The summary table names nine badges:

• profit-seeking motive
• the number of transactions
• the nature of the asset
• existence of similar trading transactions or interests
• changes to the asset
• the way the sale was carried out
• the source of finance
• interval of time between purchase and sale
• method of acquisition

On profit-seeking motive the page says an intention to make a profit supports trading but by itself is not conclusive. The page carries the date 4 August 2026.

This page cites no HMRC statement about payouts from a prop firm, so it does not say how any payout is classified or taxed. Treat this as background reading rather than tax advice, and speak to a UK tax adviser before you file.
