1.2 Our Terms and Conditions (as may be updated from time to time) shall apply in addition to these Terms. By taking any action under the Offer, you acknowledge and agree to these Terms, our Terms and Conditions and our Privacy Policy. Where there are any inconsistencies between the terms, these Terms shall take precedence over the Terms and Conditions.

‍“Eligible Customer” means an Eligible Customer who satisfies the eligibility criteria in clause 5.

“Eligible Investment Account” means a Prosper Stocks & Shares ISA, Self-Invested Personal Pension (SIPP), or General Investment Account (GIA).

“Offer Period” means the period from 27 March 2026 to 30 June 2026 at 23:59 (UK time).

“Qualifying Investment Amount” means the total amount deposited and held across all of your Eligible Investment Accounts as at 30 June 2026.

“Holding Period” means the 24-month period starting on 30 June 2026 and ending on 30 June 2028.

“Cashback” means the reward payable under this Offer in accordance with clause 7.

3.1 Members who opt in to the Offer via the Prosper app and open and fund an Eligible Investment Account with at least £5,000 during the Offer Period will receive a one-time cashback payment, subject to these Terms.

Important: The 24-month period during which you must keep your money invested (the “Holding Period”) starts on 30 June 2026 for all Eligible Customers, regardless of when you invest. This means if you invest before 30 June 2026, your total lock-in period will be longer than 24 months.

3.2 The applicable Cashback tier is determined by the Qualifying Investment Amount as set out in the table above.

3.3 Cashback is capped at £3,000 per Eligible Customer. Eligible Customers investing £1,000,000 or more will receive the same Cashback as an Eligible Customer investing exactly £1,000,000. No additional Cashback is payable in respect of any amount invested above £1,000,000.

3.4 Only one Cashback payment may be claimed per Eligible Customer under this Offer.

5.1. To qualify for the Offer, you must:

(a) be a UK resident aged 18 or over;

(b) successfully complete all onboarding, identity verification and anti-money laundering checks;

(c) opt in to the Offer via the Prosper app (opt-in is mandatory);

(d) be a savings only or new Prosper customer; 

(e) open and fund an Eligible Investment Account during the Offer Period; and

(f) comply with these Terms and our general Terms and Conditions.

6.1 The Qualifying Investment Amount is the total amount deposited and held across all of your Eligible Investment Accounts as at 30 June 2026. Funds must be deposited during the Offer Period and remain in your account(s) as at that date to count.

6.2 Only cleared funds that have been successfully deposited into an Eligible Investment Account will count toward the Qualifying Investment Amount.

6.3 Transfers from external providers (including ISA transfers) may be included where received and invested within the Offer Period.

6.4 The applicable Cashback tier will be determined by your total Qualifying Investment Amount across all Eligible Investment Accounts as at 30 June 2026.

6.5 Where an Eligible Customer holds more than one Eligible Investment Account, Prosper will aggregate the total balance across all such accounts as at 30 June 2026 to determine the applicable Cashback tier.

7.1 Cashback will be paid into your Prosper wallet on or before 15 July 2026, provided you have satisfied all qualifying conditions.

7.2 Cashback is non-transferable and non-exchangeable, cannot be substituted for another reward, and will not be paid as cash outside the Prosper platform.

7.3 Prosper reserves the right to change the method or destination of Cashback payment where required for operational, regulatory or legal reasons. Where reasonably practicable, Prosper will give reasonable notice of any such change.

8.1 You must maintain at least the Qualifying Investment Amount across your Eligible Investment Account(s) for the full Holding Period of 24 months.

8.2 The Holding Period begins on 30 June 2026 for all qualifying Eligible Customers, regardless of when their account was opened or funded during the Offer Period.

8.3 The requirement applies to the original Qualifying Investment Amount only and is not affected by market movements.

9.1 If you make a withdrawal during the Holding Period that reduces your total account balance below the Qualifying Investment Amount, Prosper reserves the right to recover the cashback in full.

9.2 Market-driven fluctuations in the value of your investments will not trigger clawback, provided no withdrawal has been made.

10.1 Stocks & Shares ISA: Annual ISA subscription limits apply and are subject to HMRC rules. For the 2025/26 tax year, the subscription limit is £20,000; the same limit applies for 2026/27. Accounts opened on or before 5 April 2026 will use your 2025/26 allowance; accounts opened from 6 April 2026 will use your 2026/27 allowance. ISA transfers from external providers do not count as a new subscription for allowance purposes, but fresh cash deposits do. It is your responsibility to ensure you do not exceed your annual ISA subscription limit.

10.2 SIPP — important access restriction: pension funds cannot ordinarily be accessed until age 55 (rising to 57 from 2028). This is significantly longer than the 24-month Holding Period under this Offer. If you invest via a SIPP, you will not be able to access those funds until you reach pension age, even after the Holding Period ends. By choosing a SIPP as your account type, you acknowledge this restriction.

10.3 SIPP — tax: cashback paid into a SIPP will be treated as a pension contribution and will count toward your annual pension allowance (currently £60,000, or £10,000 if you are subject to the Money Purchase Annual Allowance). Exceeding your allowance may result in an HMRC tax charge. We recommend you take independent financial advice before choosing a SIPP as your qualifying account under this Offer.

11.1 This Offer may only be used once per Eligible Customer and cannot be combined with any other Prosper promotion. Eligible Customers currently enrolled in the PROSPERCASH promotion cannot combine that offer with this one.

11.2 Prosper reserves the right to disqualify any Eligible Customer where it reasonably suspects fraud, abuse, or gaming of the Offer, multiple or duplicate accounts, or breach of these Terms or our general Terms.

12.1 This Offer should not form the basis of any decision to invest.

12.2 As with all investing, your capital is at risk, the value of investments may go down as well as up, and you may get back less than you invest.

12.3 Tax treatment depends on individual circumstances and may change in the future. If you are unsure, you should seek independent financial advice.

13.1 Prosper reserves the right to amend, suspend or withdraw this Offer at any time. Where you have already opted in to the Offer but have not yet met the qualifying criteria, Prosper will use reasonable endeavours to provide at least 7 days’ prior notice before withdrawing the Offer, except where withdrawal is required immediately for legal or regulatory reasons.

13.2 If the Offer is withdrawn, Eligible Customers who have already met the qualifying criteria will remain eligible under the Terms in force at that time.

14.1 We’re committed to making this Offer work as described. The legal limitations below apply alongside your normal consumer rights, which are not affected.

14.2 To the fullest extent permitted by law, Prosper excludes all implied warranties and representations relating to the Offer.

14.3 Prosper shall not be liable for any loss, damage or delay arising from participation in the Offer except where required by law.

14.4 Nothing in these Terms excludes or limits Prosper’s liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited by law. Nothing in these Terms affects your statutory rights.

15.1 These Terms are governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.
