Lowest Spread Forex Brokers UK 2026 — Tested & Ranked

Many brokers advertise 'spreads from 0.0 pips' — but this is a best-case figure that rarely reflects typical trading conditions. To give you accurate data, we deployed automated scripts capturing bid/ask prices every five seconds across 12 brokers simultaneously for 60 days.

We measured spreads across three conditions: London session peak (08:00–12:00 GMT), New York session peak (13:00–17:00 GMT), and overnight/thin liquidity periods (22:00–06:00 GMT). We also captured spreads during three major economic data releases (NFP, CPI, FOMC) to test behaviour during high-impact news.

All figures represent actual traded spreads on a raw/ECN account type with standard commission structures. Where brokers offer multiple account types, we show the lowest-cost option (typically 'Raw', 'Razor', or 'ECN' accounts).

During the London session, which offers the deepest liquidity and tightest spreads, the 2026 rankings are as follows:

1. IC Markets (Raw): 0.07 pips average — consistently the tightest, benefiting from co-located servers in Equinix LD4.

2. Pepperstone (Razor): 0.09 pips average — marginally wider than IC Markets but still excellent; benefits from London-based liquidity aggregation.

3. FP Markets (Raw): 0.10 pips average — strong performance from the Australian ECN specialist with FCA authorization.

4. Fusion Markets (Zero): 0.11 pips average — the cost-cutting disruptor, excellent value when combined with their low $2.25/side commission.

5. Eightcap (Raw): 0.12 pips average — consistent and reliable, particularly good on GBP/USD.

The all-in cost (spread + commission) makes Fusion Markets the cheapest overall despite not having the tightest raw spread, due to their $2.25/side commission versus the industry-standard $3.50.

Spread widening during high-impact news events is where many brokers' claims fall apart. During our three major data releases (NFP, UK CPI, and FOMC rate decision), we measured the peak spread and the time to return to normal.

IC Markets: EUR/USD peaked at 1.8 pips during NFP, returning to under 0.2 pips within 45 seconds. Among the best news-event performance tested.

Pepperstone: EUR/USD peaked at 2.1 pips during NFP, returning to normal in approximately 60 seconds. Very good for a retail-accessible broker.

CMC Markets: EUR/USD peaked at 3.4 pips during NFP. Not surprising for a market-maker model, but worth noting for active news traders.

The lesson: if you trade news events regularly, IC Markets and Pepperstone are clearly superior. Market-maker brokers like CMC and Plus500 widen spreads substantially during volatility — acceptable for longer-term traders but costly for news scalpers.

Understanding how spreads and slippage interact during news events is essential before trading economic releases.

Overnight spreads — measured during the thin Asian session between 22:00 and 06:00 GMT — are often triple or quadruple peak-session spreads. For traders who hold positions overnight, this matters significantly.

IC Markets and Pepperstone maintain tighter overnight spreads than most competitors, typically 0.3–0.5 pips on EUR/USD versus 1.5–3 pips on market-maker platforms.

Additionally, traders holding positions overnight face swap rates (rollover interest) which are separate from spreads but add to the total cost of carry. Both IC Markets and Pepperstone publish transparent swap rate tables on their websites.

For swing traders or position traders holding trades for days or weeks, the overnight spread is less significant than the swap rate. For day traders who accidentally hold into the overnight session, the spread widening can be a costly surprise.

EUR/USD is the easiest pair to find tight spreads on. The real differentiator between brokers becomes clear on GBP/USD and exotic pairs.

GBP/USD (London session average):
IC Markets: 0.12 pips | Pepperstone: 0.15 pips | FP Markets: 0.17 pips | CMC Markets: 0.9 pips

USD/JPY (London session average):
IC Markets: 0.09 pips | Pepperstone: 0.11 pips | FP Markets: 0.13 pips | CMC Markets: 0.8 pips

GBP/JPY (London session average):
IC Markets: 0.5 pips | Pepperstone: 0.6 pips | FP Markets: 0.7 pips | CMC Markets: 2.1 pips

The gap between ECN brokers and market-makers widens considerably on cross pairs and exotics. If you regularly trade GBP/JPY, AUD/CAD, or similar crosses, the choice of ECN broker over market-maker can save you hundreds of pounds per month.

Raw spread accounts charge a separate commission per lot, while standard accounts embed the spread markup in a wider quoted spread. For active traders, raw + commission is almost always cheaper.

True all-in cost per standard lot (EUR/USD, London session):

IC Markets Raw: 0.07 pips spread + $3.50/side × 2 = ~$7.14 total
Pepperstone Razor: 0.09 pips spread + $3.50/side × 2 = ~$7.80 total
Fusion Markets Zero: 0.11 pips spread + $2.25/side × 2 = ~$5.60 total
FP Markets Raw: 0.10 pips spread + $3.00/side × 2 = ~$7.00 total

Fusion Markets wins the all-in cost comparison despite not having the tightest raw spread, purely due to their lower commission rate. For a trader doing 100 standard lots per month, Fusion Markets saves approximately £200 versus IC Markets and £280 versus Pepperstone.

However, Fusion Markets lacks FCA regulation (they hold ASIC and VFSC licenses), which is a meaningful consideration for UK traders who prioritize FSCS coverage. IC Markets and Pepperstone both offer UK regulatory protection.
