Get Up to £200 Cashback on Your Investments with IG (2025)
IG UK has launched an enhanced winter promotion offering 10% cashback on investments for new customers. Running from 21st November to 31st December 2025, this offer lets you earn up to £200 based on your average invested value. We analyzed the terms to help you understand how to maximize this promotion.
Our Verdict: Is This Worth It?
Based on our analysis, this cashback promotion offers exceptional value compared to random share allocations. Unlike lottery-style bonuses where most participants receive the minimum, the 10% cashback directly rewards higher investment amounts with proportional returns.
The mathematics are straightforward: invest £2,000 on average throughout the promotional period and you'll receive the maximum £200 cashback. Smaller investments still earn proportionally, with a £500 average investment returning £50 cashback.
How the Promotion Works
The cashback calculation is based on your daily average invested value between 21st November and 31st December 2025. IG calculates this by tracking your portfolio value each day during the promotional period, then applying 10% to the average.
To qualify, you need to open a new IG share dealing account (GIA, ISA, or SIPP), make your first trade worth at least £50, and maintain a minimum £50 portfolio value from January to March 2026. The cashback is credited to your GIA by 30th April 2026.
Calculating Your Potential Cashback
The 10% cashback applies to your daily average invested value, capped at £200 maximum. Here's what different investment levels could return:
- £500 average investment = £50 cashback
- £1,000 average investment = £100 cashback
- £1,500 average investment = £150 cashback
- £2,000+ average investment = £200 cashback (maximum)
Keep in mind that your "average invested value" fluctuates with market movements. If you invest £1,000 and the market rises 10%, your average value increases accordingly, potentially boosting your cashback.
Key Terms and Restrictions
We reviewed the full terms and conditions to identify important requirements:
The promotional period runs from 21st November 2025 to 31st December 2025 at 23:59 UK time. You must open your account and make your first £50+ trade within this window to qualify.
The holding requirement extends beyond the promotional period. You must maintain an active investment portfolio with a minimum £50 value from January to March 2026. If your portfolio drops below £50 due to market fluctuations but you maintain your original investment, you still qualify.
Your cashback is credited to a General Investment Account (GIA), regardless of whether you invest through an ISA or SIPP. This has tax implications since cashback in a GIA may be considered taxable income.
The promotion is limited to new share dealing customers only. If you've previously held any IG share dealing account (GIA, ISA, or SIPP), you're not eligible. However, existing IG spread betting or CFD account holders who've never used share dealing can participate.
IG's Investment Platform Features
Beyond the promotion, IG offers several attractive platform features:
Zero commission trading on all UK stocks and ETFs means your investment value isn't reduced by trading costs. This is particularly valuable if you plan to build a diversified portfolio.
IG pays 4% AER variable interest on uninvested cash balances up to £100,000. You must hold an open position or have traded during the month to earn interest.
The platform supports three account types: General Investment Account (GIA) for flexible investing, Stocks and Shares ISA for tax-free growth up to £20,000 annually, and Self-Invested Personal Pension (SIPP) for retirement savings with tax relief.
IG has won multiple awards including Best Share Dealing Platform 2024 from Yourmoney.co.uk and Best for Low-cost ISA from Boring Money Best Buy Awards 2024.
Who Should Consider This Offer
This promotion suits investors planning to commit meaningful capital during the promotional period. The 10% return rewards larger investments proportionally, making it ideal for those ready to invest £1,000 or more.
Long-term investors benefit most since the holding requirement extends to March 2026. If you're planning to build a portfolio you'll hold for years, the four-month commitment is minimal.
ISA investors approaching tax year end might find particular value. You can use part of your £20,000 ISA allowance before April 2026 while earning cashback on the investment.
Cost-conscious investors appreciate the combination of zero commission trading plus 10% cashback. Your £50 minimum investment goes entirely toward shares, plus you earn a substantial return on top.

Claiming Your Cashback
The process requires opening an IG account and completing your first £50+ trade between 21st November and 31st December 2025. We recommend investing early in the promotional period to maximize your average invested value.
Account opening typically takes 1-2 business days including identity verification. Fund your account via bank transfer, debit card, Apple Pay, or Google Pay before placing your first trade.
Remember that your cashback arrives by 30th April 2026, approximately four months after the promotional period ends. This delay allows IG to verify compliance with the January-March holding requirement.
Important Considerations
While this promotion offers exceptional returns, consider several factors before participating:
The extended holding period requires maintaining your investment from November 2025 through March 2026, approximately five months total. Market movements during this period could affect your portfolio value.
Tax implications apply since cashback is credited to a GIA. The £200 maximum cashback may be considered taxable income depending on your circumstances. Consult a tax professional for personalized advice.
You cannot combine this promotion with other IG offers. If you participate in multiple promotions, only the first one you began applies.
Asset transfers from other brokers do not count as a "First Trade" for this promotion. You must place an actual buy order worth at least £50 to qualify.
Our Bottom Line
IG's 10% cashback promotion offers exceptional, predictable value for new investors willing to commit capital through March 2026. Unlike random share allocations, the cashback amount directly correlates with your investment size, rewarding those who invest more.
The maximum £200 return requires maintaining approximately £2,000 average investment during the promotional period. Smaller investments still earn proportionally, making this accessible for various budget levels.
We recommend this promotion for investors planning to hold positions long-term who appreciate predictable returns over lottery-style bonuses. The combination of zero commission trading, 4% cash interest, and 10% cashback creates a compelling package for new IG customers.

Frequently Asked Questions
How is the 10% cashback calculated?
IG calculates your cashback based on the daily average invested value of your portfolio between 21st November and 31st December 2025. They track your portfolio value each day, calculate the average, then apply 10% to that figure, capped at £200 maximum.
What's the minimum investment required to participate?
You must make a first trade worth at least £50 to qualify for the promotion. However, the more you invest, the higher your cashback. To earn the maximum £200, you need an average invested value of approximately £2,000 during the promotional period.
How long do I need to hold my investment?
You must maintain an active investment portfolio with a minimum £50 value from January to March 2026. This means holding your investment for approximately four months after the promotional period ends.
When will I receive my cashback?
IG will credit your cashback to your General Investment Account (GIA) by 30th April 2026. This is approximately four months after the promotional period ends, allowing time to verify the holding requirement.
Can I participate if I have an existing IG account?
Only if you've never held an IG share dealing account (GIA, ISA, or SIPP). Existing IG spread betting or CFD customers who've never used share dealing services can participate. Previous share dealing customers are not eligible.
Why is cashback credited to a GIA instead of my ISA?
IG credits all promotional rewards to General Investment Accounts regardless of where you made your initial investment. This is standard practice for bonus payments, though it may have tax implications since GIA holdings don't benefit from ISA tax protections.
Does transferring shares from another broker count as my first trade?
No, transferring assets to IG from a third party does not count as a "First Trade" for this promotion. You must place an actual buy order worth at least £50 during the promotional period to qualify.
