The stamp the industry measures itself against: FCA authorisation for CFD and rolling spot forex under FSMA - MIFIDPRU own-funds tiers from £75,000 to £750,000, the PS19/18 retail conduct rules, and credibility no offshore desk can price. We file from our own London office.
Updated
The benchmark desk of global FX.
The United Kingdom regulates forex and CFD brokerage as investment business: dealing in, arranging or advising on contracts for difference and rolling spot forex requires FCA authorisation under the Financial Services and Markets Act, with permissions matched to the model. The prudential frame is the IFPR: own-funds floors under MIFIDPRU run £75,000 for firms that neither deal nor hold client money, £150,000 where client money and assets are held, and £750,000 for dealing on own account - with the K-factor and fixed-overheads calculations layered above the floors. The retail conduct layer is equally defined: the PS19/18 rules cap CFD leverage at 30:1 to 2:1 by asset class, mandate negative balance protection and margin close-out, and ban inducements - the framework that ended the bonus-and-500:1 era.
Why brokers still queue for it: London remains the world's largest FX centre, an FCA permission converts into banking, liquidity and institutional relationships nothing else matches, and UK client money rules (CASS) are the segregation standard counterparties actually trust. The costs are real - capital, substance, a supervisor that reads everything, and the timeline runs 9-15 months. The reward is the licence that makes every other conversation easier. We run the file from our own office at 7 Bell Yard.
FCA authorisation under FSMA: MIFIDPRU own funds £75k/£150k/£750k by model, CASS client money, PS19/18 retail rules (leverage 30:1-2:1, negative balance protection, no inducements).
The reward: the benchmark stamp of global FX, in the world's FX capital. We file from our own London office.

The UK forex licence: frequent questions.
What licence does a forex broker need in the UK?+
FCA authorisation under FSMA with permissions matched to the model - dealing in investments as principal for market makers, matched principal or arranging for agency brokers - covering CFDs and rolling spot forex as MiFID-derived investments.
What capital does the FCA require?+
MIFIDPRU own-funds floors: £75,000 for firms neither dealing nor holding client money, £150,000 where client money is held, £750,000 for dealing on own account - with K-factor and fixed-overheads requirements calculated above the floors.
What are the PS19/18 retail rules?+
The FCA's CFD framework: leverage capped 30:1 to 2:1 by asset class, mandatory negative balance protection and margin close-out, and a ban on bonuses and inducements. The product must be engineered for them from day one.
How long does authorisation take?+
Realistically 9-15 months - the FCA reads the full file, tests SMF candidates under SM&CR and probes the dealing model. Completeness and prepared people are the speed levers; both are our job.
What substance is expected?+
A UK company genuinely run from the UK: resident SMF holders, compliance and MLRO, CASS-grade operations and offices the supervisor can visit. The FCA authorises businesses, not addresses.
How are UK brokers taxed?+
25% corporation tax (19% small-profits rate), VAT-exempt financial services, no dividend withholding, R&D relief on platform build-out and the world's deepest treaty network.
What is CASS and why does it matter commercially?+
The UK client-money regime - segregation, daily reconciliation, annual audit. It is the standard counterparties trust by name: passing CASS cleanly converts into banking and liquidity relationships.
Does the UK licence passport into the EU?+
No - that ended with Brexit. UK-authorised brokers serve the UK and non-EU world; EU retail flow needs an EU MiFID licence like the CySEC CIF, and serious groups hold both. We sequence the pair.
Is the UK worth it against offshore alternatives?+
Different products entirely: offshore licences price speed, the FCA prices trust. Institutional counterparties, UK retail and premium PSPs require the real thing - groups typically pair an FCA core with offshore satellites, cleanly separated.
Why Prifinance for the UK?+
Our own office in London, SM&CR preparation as a dedicated workstream, and a file built for a regulator that reads everything. The home-desk advantage in the market that matters most.
What licence?+
FCA authorisation - permissions by model.
Capital?+
£75k/£150k/£750k + K-factors.
Retail rules?+
PS19/18 - 30:1, NBP, no bonuses.
How long?+
9-15 months realistic.
Substance?+
Real UK operations, tested people.
Taxes?+
25%/19%; no dividend WHT.
CASS?+
The trusted client-money standard.
EU passport?+
Gone - pair with a CySEC CIF.
Vs offshore?+
Trust vs speed - pair deliberately.
Why you?+
