Commercial disclosure: Refer & Save may earn commission when readers use clearly identified compensated links and complete a qualifying action. Check the provider’s current terms before acting.
A referral code or referral link records that an existing customer, partner or publisher introduced a new customer to a business. The company uses that identifier to decide whether the sign-up qualifies and whether the new customer, the referrer or both should receive a reward.
A code does not guarantee a reward. The current programme terms decide who is eligible, which route must be used, what action is required and when any benefit becomes payable. Check those conditions before opening an account, placing an order or moving money.
Referral code meaning
A referral code is a unique combination of letters, numbers or a person's name that attributes a new sign-up or purchase to a particular referrer. Some programmes use a clickable referral link instead. The link normally carries the identifier automatically, so the new customer does not have to type a code.
Referral programmes are common across current accounts, business accounts, investing platforms, shopping, delivery apps, travel, broadband, energy, mobile services and subscriptions. The underlying idea is the same: a business rewards an introduction when its stated conditions are completed.
The reward might be cash, account credit, points, a voucher, a free item, a discount, a free subscription period or an investment asset such as a share. It can be paid to the new customer, the existing customer, both people or only one of them.
Key referral terms
| Term | Meaning | What to check |
|---|---|---|
| Referrer | The existing customer or partner who shares the code or link | Whether the referrer receives a reward and whether public sharing is allowed |
| Referred customer | The person joining or buying through the referral | New customer, age, location, product and household eligibility |
| Qualifying action | The step that must be completed before a reward is considered | Purchase, deposit, card payment, subscription, approved application or another stated action |
| Tracking window | The time allowed for completing the required steps | Start date, closing date and whether pending or reversed transactions count |
| Reward window | The expected time between qualification and payment | Whether the reward is instant, delayed or subject to a returns or validation period |
| Clawback | A rule allowing a reward to be reversed | Cancellation, refund, withdrawal, account closure or failure to maintain a required balance |
| Referral cap | A limit on referrals or rewards | Per person, household, month, campaign or lifetime limits |
How referral codes work
Most referral programmes follow the same broad sequence.
- An existing customer receives a personal code or link from the provider.
- The new customer opens the referral route before registering or ordering.
- The provider records the referrer through the code, link or account details.
- The new customer completes the stated qualifying action.
- The provider checks eligibility, payment status, cancellations and programme limits.
- The reward moves from pending to approved.
- The provider issues cash, credit, points, a voucher, discount or another benefit.
The route matters. Some programmes require the referral link to be opened before account creation. Others display a code field during registration or checkout. A few use the referred person's name, email address or mobile number. Follow the provider's stated method rather than assuming a code can be added after the account has been created.
Referral code versus referral link
A referral code must normally be entered into a specific field. A referral link contains tracking information in the web address and may attach the referral automatically.
If a provider supplies both, use the referral link first and enter the code only where the provider asks for it. Do not assume that using both creates two rewards. The code and link often identify the same referral.
Before continuing, check that the link reaches the provider's genuine website or official app route. A referral should never require you to give the referrer your password, one-time security code, full card information, identity documents or remote access to your device.
Referral code versus promo code and voucher code
These labels can look similar at checkout, but they describe different relationships.
| Type | Usual purpose | Typical result |
|---|---|---|
| Referral code | Records an introduction from an existing customer or partner | May reward the new customer, referrer or both after conditions are completed |
| Referral link | Carries referral tracking in a clickable URL | Usually records the referral automatically before sign-up or purchase |
| Promo code | A campaign code issued by the business or an authorised partner | Usually applies a discount, gift, credit or introductory benefit |
| Voucher code | A broad consumer term for a checkout discount or benefit | May reduce the order price or trigger a separate benefit |
| Affiliate link | Records that a publisher or creator referred a sale | The publisher may earn commission; the shopper receives a benefit only if the offer says so |
| Loyalty programme | Rewards continuing custom rather than one introduction | Usually provides points, member prices, stamps or account benefits over time |
A promotional code can also be an affiliate code, and a referral link can be shared by a commercial publisher. The label does not decide the reward. The live terms and the confirmation shown during the customer journey are what matter.
Who receives the referral reward
Referral programmes generally use one of four reward structures:
Both people receive the same benefit.
The new customer and referrer receive different benefits.
Only the new customer receives a benefit.
Only the referrer receives a benefit.
ReferAndSave offer pages should state these benefits separately. A headline such as "Get £50" is incomplete if £50 is the combined value across two people or if only the referrer receives it.
Check the reward format as well as the headline amount. £20 of restricted account credit is not always equivalent to £20 cash. Points may have variable value. A voucher may expire or work only with one retailer. A free item may still require delivery payment or a minimum basket.
Who qualifies as a new customer
"New customer" does not have one universal definition. Depending on the programme, it may exclude someone who previously:
Created an account but never used it.
Took a free trial.
Held a different product with the same provider.
Closed an account and later returned.
Used another email address or mobile number.
Lives at an address where another person has used the offer.
Has already been referred or received a welcome offer.
Do not create duplicate accounts or use another person's identity to bypass a restriction. If the definition is unclear, ask the provider before completing a paid or irreversible action.
For practical checks, see the new-customer eligibility section of the Referral Code Not Working guide.
How to find a genuine referral code
Start with a provider's official website, app, account area, help centre or current programme terms. Search for terms such as refer a friend, invite, rewards or referral terms. A legitimate programme should explain the eligible audience, qualifying action, reward and expected timing.
A referral directory can help you discover an offer, but the provider remains the source of truth. Check that the directory identifies when the offer was verified, distinguishes the new-customer benefit from the referrer benefit and links to the current provider route where possible.
Avoid relying on an old screenshot, a search-result snippet or a social post that does not link to the programme conditions. Offers can be changed, paused or withdrawn, and a code that still looks valid may no longer create a reward.
ReferAndSave explains its checking process in How We Source and Verify Referral Offers.
How to use a referral code without losing the reward
Use this order unless the provider gives different instructions:
- Read the offer and product terms before starting.
- Confirm that you qualify as a new customer for the correct UK product.
- Check the exact qualifying action, amount and deadline.
- Open the official referral link or copy the code accurately.
- Complete registration or checkout through the required route.
- Confirm that the code, discount or referral message appears where the provider says it should.
- Save the offer terms, sign-up confirmation and transaction evidence.
- Complete only the required action and avoid unnecessary spending.
- Wait for the stated validation and payment period.
- Contact the provider if the code fails or the reward becomes overdue.
If the code is rejected, use the decision process in Referral Code Not Working. If the qualifying action has been completed but the reward has not arrived, use Referral Reward Not Received.
How to judge whether the reward is worthwhile
Start with the product rather than the bonus. Ask whether you would still want the account, service or purchase without the referral reward.
Then calculate the practical value:
Reward value minus required spending minus fees minus delivery costs minus any cost of keeping the product for the required period.
A large headline reward can have poor net value if it requires an unsuitable subscription, high fees, unnecessary spending or investment risk. Conversely, a modest discount can be useful when it applies to a purchase you already intended to make.
For banking, credit, insurance, investing and crypto products, suitability, charges and risk should carry more weight than the sign-up reward. A bonus does not make an unsuitable product suitable.
Can referral codes be combined with cashback or other discounts
Sometimes, but never assume that they can. A referral link, cashback website, browser extension and voucher code may compete for the same tracking attribution. A checkout might also accept only one promotion.
Check the referral terms and the other promotion's conditions before combining them. If neither source confirms that stacking is allowed, compare the routes separately and use the one that offers the best reliable outcome.
What the referrer can see
The information visible to a referrer varies. A provider might show only that an invitation is pending or completed. Some programmes show a first name, status or reward progress. The referrer should not need your password, security code, card information or identity documents.
Read the provider's privacy information if you want to know what data is shared. Contact the provider directly if the referral screen appears to disclose more information than expected.
How to share a referral code responsibly
Explain the material benefit and the main condition accurately. State whether you receive a reward, and do not describe a variable or conditional benefit as guaranteed.
Public sharing can be restricted by the programme. It can also become advertising where the person posting has been incentivised. Read Referral Code Etiquette and UK Sharing Rules before sharing codes publicly or repeatedly.
Are referral codes safe
Referral codes are a normal marketing method, but the surrounding message or destination can still be false. Check the domain, provider identity, programme terms and information requested before continuing.
Stop if someone asks you to:
Send a password or one-time passcode.
Pay the referrer to release a reward.
Transfer money to a personal account outside the provider's stated process.
Install remote-access software.
Create multiple accounts or use false details.
Act immediately without reading the conditions.
If you believe you have lost money or account access through an online scam, use the current reporting route on GOV.UK and contact the relevant bank or payment provider promptly.
Frequently asked questions
Can I use a referral code if I already have an account
Only if the current programme terms allow existing customers to participate. Many offers are limited to genuinely new customers, and an unused or dormant account can still make you ineligible.
Do referral codes always give the new customer a reward
No. Some programmes reward both people, some reward only the new customer and some reward only the referrer. Check the two benefits separately.
Can a referral code be added after registration
Often it cannot. Some providers can correct a missing referral, but others require the link or code before account creation. Contact the provider before completing further qualifying actions.
Does an accepted code mean the reward is guaranteed
No. Acceptance may only record the referral. The provider can still check customer eligibility, payment status, cancellations, returns, deadlines and referral caps.
Can I use more than one person's referral code
Normally one sign-up can be linked to only one referrer. Attempting to apply several codes can invalidate tracking or breach the programme rules.
Is a referral code the same as an affiliate link
Not necessarily. A customer referral identifies an existing customer who made an introduction. An affiliate link records a commercial publisher or partner. A campaign can use both arrangements, so check the disclosure and terms.
What should I do when a referral code does not work
Do not create another account immediately. Check the code, route, product, country, eligibility and deadline, save the error message and contact the provider. Use the complete Referral Code Not Working guide.
