Amex Business Platinum: 100,000 Points + £150 Selfridges Until January

American Express has doubled the sign-up bonus on its Business Platinum card to 100,000 Membership Rewards points, and thrown in a £150 Selfridges gift card on top - making this the strongest welcome offer the card has ever carried. The offer runs until 12 January 2027, and comes with a revised spend target of £12,000 in the first three months. If you have been waiting for the right moment to apply, this is almost certainly it.

The standard welcome bonus on the Business Platinum sits at 50,000 Membership Rewards points. For a limited period, that has been doubled to 100,000 points - and there is a £150 Selfridges gift card added on top of that. Both the points and the gift card are subject to meeting the spending requirement.

The spending requirement of £12,000 over three months works out at £4,000 per month - a meaningful bar, but one that many small business owners will clear through everyday business outgoings like suppliers, software subscriptions, and travel.

Membership Rewards points are one of the most flexible point currencies available to UK cardholders, transferring 1:1 into Avios (for British Airways, Iberia, Vueling, and Aer Lingus), as well as into programmes including Virgin Atlantic Flying Club and a range of hotel currencies.

At a conservative valuation of 1p per Avios, 100,000 Membership Rewards transferred to Avios gives you roughly £1,000 in flight value. Stretch that to a more aspirational redemption - say, business class to a long-haul destination - and many points enthusiasts would value those 100,000 Avios at £1,500 to £2,000 or more. You can check what your Avios balance could be worth on the Smart With Points Avios Value Calculator.

Add the £150 Selfridges gift card and the total package - even at the conservative 1p per point floor - is worth approximately £1,150 in combined value for meeting a spend target that many business owners would reach naturally.

This offer is aimed squarely at UK business owners, sole traders, and company directors. You will need to apply in a business name (limited company, partnership, or sole trader structure all qualify). Personal Amex cardholders who have never held an Amex Business card are the most likely to be eligible for the full welcome bonus - but eligibility can depend on your relationship with American Express.

Not sure if you qualify? Check your eligibility before applying with the Amex Welcome Bonus Eligibility Tool - it takes less than a minute and does not affect your credit score.

To maximise the offer once you have the card, put as much of your regular business spending through it as possible from day one. Think recurring costs - software licences, cloud hosting, advertising spend, contractor invoices - alongside any larger one-off purchases you have planned in the next three months.

The spend target is the biggest factor to consider carefully. At £12,000 in three months, this is higher than the standard offer period spend requirement, and if you do not meet it you will not receive the bonus. Only put spending on the card that you were going to make anyway - do not manufacture spend artificially.

The Business Platinum also carries a significant annual fee, so factor that in when calculating the net value of the welcome bonus. The card comes with a range of ongoing benefits - lounge access, travel credits, and hotel status - that can offset the fee for frequent travellers, but it is worth reading the full terms before applying.

American Express bonus eligibility rules apply. If you currently hold, or have recently held, an Amex Business Platinum, you are unlikely to qualify for the welcome bonus again. The same restriction does not generally apply if you hold personal Amex cards but have never had the Business Platinum specifically.

Yes, in most cases. American Express treats personal and business cards separately for bonus eligibility purposes. If you currently hold a personal Amex card but have not held the Business Platinum before, you should be eligible - though it is always worth checking with American Express directly before applying.

Membership Rewards transfer 1:1 into Avios (usable with British Airways, Iberia, Vueling, and Aer Lingus), as well as into Virgin Atlantic Flying Club and several hotel loyalty programmes. Avios is the most popular destination for UK cardholders, given the range of redemption options available.

The 100,000-point welcome bonus and the £150 Selfridges gift card offer both close on 12 January 2027. There is no indication that the offer will be extended, so if you are planning to apply, do not leave it until the final days.

No - the spend target has been increased as part of the promotional offer. The standard terms carry a lower spend requirement; the doubled bonus comes with the higher £12,000 in three months threshold. Make sure you are confident you can meet this before applying.

A doubled welcome bonus of 100,000 Membership Rewards points plus a £150 Selfridges gift card makes this the most compelling offer the Amex Business Platinum has ever carried in the UK. At even a conservative valuation, the points alone are worth around £1,000 - and for business owners who will naturally clear the £12,000 spend target, the maths are hard to argue with. The offer closes on 12 January 2027 - plenty of time to decide, but no reason to delay if you know this card is right for you.
