Which UK broker has the lowest spreads?
On published data, Pepperstone’s Razor account — and it is the only firm here that lets you check the claim, because it is the only one publishing an average with a measurement window attached.
That is the finding that should shape how you read every other comparison of this kind. A minimum spread is the tightest price the broker has ever quoted; it tells you nothing about what you will pay at 3pm on a payrolls Friday. An average tells you something — but only if you know when it was measured.
EUR/USD spreads compared
Read that last column before the others. Only one broker on this page publishes a current, dated average. IG publishes one measured in January 2021 — before two rate-hiking cycles and a change of market regime. It is not wrong of IG to publish it, but it should not be compared like-for-like against a figure from last quarter. Any table showing six brokers’ average spreads side by side has invented at least four of them.

The commission is the other half of the price
A raw account with a 0.0 spread is not free. The cost moves into a commission, and at the same broker it differs by platform — which is worth knowing before you pick one.
Same broker, same trade, different price. A standard lot of EUR/USD costs $6.00 round turn on cTrader and $7.00 on TradingView. Over 200 lots a year that is a $200 difference decided entirely by which platform you clicked at signup. Commission on MT4 and MT5 is charged in full when the position opens, not split across open and close.
