Vantage vs IG vs Interactive Brokers UK Fees: 2025 Guide

*CFD Risk Warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. A high percentage of retail investor accounts lose money when trading CFDs with these providers. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.*

The Vantage vs IG vs Interactive Brokers UK fees comparison reveals that Vantage often provides the most competitive FTSE 100 spreads for retail traders, frequently starting at 1.0 pip. IG offers extensive liquidity but higher overnight costs, while Interactive Brokers (IBKR) excels for DMA-style institutional pricing but maintains a more complex fee structure for smaller accounts.

Choosing the Best Broker for FTSE 100 Trading in the UK

For British traders looking to capitalise on the London Stock Exchange’s primary index, the "UK 100" or FTSE 100 serves as a cornerstone of most portfolios. However, the profitability of index trading is heavily dictated by two primary costs: the bid-ask spread and overnight funding fees (swaps).

While Vantage has positioned itself as a high-speed, low-cost alternative, incumbents like IG and Interactive Brokers offer different value propositions depending on your trade volume and holding period.

FTSE 100 Spread Comparison: Vantage vs IG vs IBKR

The spread is the immediate cost you pay to enter a trade. In the highly liquid FTSE 100 market, even a 0.5 pip difference can significantly impact the bottom line of a day trader.

• Vantage: Known for aggressive pricing, Vantage maintains tight spreads on indices. For the FTSE 100, traders often see spreads ranging from 1.0 to 1.2 pips during peak London market hours. Their RAW ECN account further reduces these via a commission-based model.
• IG Markets: As a market leader, IG offers a "standard" spread of around 1.0 pip during main hours, but this can widen significantly during the out-of-hours (Grey Market) sessions.
• Interactive Brokers: IBKR uses a Tiered or Fixed commission model. While their raw spreads are institutional-grade (often 0.1 to 0.5), the addition of minimum commissions makes them less ideal for traders with smaller ticket sizes.

Overnight Funding Fees: The Silent Profit Killer

If you hold a FTSE 100 position past 10:00 PM UK time, you will incur an overnight funding charge. This is essentially interest paid on the leveraged portion of your trade.

1. Vantage: Vantage uses a transparent swap-rate model based on the SOFR/SONIA benchmarks plus a small administrative markup. They are frequently lauded for having some of the lowest "carry costs" for swing traders.
2. IG: IG’s funding rates are typically SONIA +/- 2.5% to 3%. While standard for the industry, these can eat into profits if a position is held for several weeks.
3. Interactive Brokers: IBKR offers the most professional interest rate tiers. They typically charge BM (Benchmark) + 1.5%. However, navigating their "Account Management" portal to calculate these fees is notoriously difficult for beginners.

Platform Technology and Execution Speed

Costs are not just about pips and swaps; they are also about slippage.

• Vantage: Utilises Equinix fibre-optic networks to ensure ultra-low latency. This is critical during the 8:00 AM London open when the FTSE 100 experiences maximum volatility.
• IG: Offers the proprietary IG platform and L2 Dealer. While feature-rich, the web-based version can occasionally experience lag during high-red-news events.
• Interactive Brokers: Their Trader Workstation (TWS) is the gold standard for data, but its steep learning curve often deters retail traders.
