Most receipts you receive at the checkout are printed on thermal paper. This paper does not use ink. Instead, it is coated with a chemical that reacts to heat from the printer to create text. Because this chemical coating remains active, the print continues to react to heat, light, and friction long after you leave the shop. This is why paper receipts fade and eventually become unreadable. You cannot stop this process, but you can manage it by creating a digital copy that lasts.
Why your receipt matters
Under the Consumer Guarantees Act 1993, goods sold to you must be of acceptable quality, fit for purpose, and last a reasonable time given their price and type. If a product fails, the retailer is responsible for providing a remedy. While you do not need the original paper receipt to make a claim, you do need proof of purchase. A bank statement, a loyalty card record, or an email confirmation can serve as evidence. However, having a clear copy of the original receipt makes the process much easier. If you rely on paper, you will likely find the text has vanished when you need it most. A faded receipt can make it difficult to prove when and where you bought an item, especially for high-value electronics or appliances. Do not rely on the store's printed warranty period either, as your rights under the Consumer Guarantees Act often last longer than a manufacturer's warranty. You can use Hey Proofy to photograph or upload a receipt as soon as you get home, ensuring you have a permanent record.
How to keep a readable copy
The most effective way to keep a copy that lasts is to digitise it immediately. You can take a clear photo of the receipt or scan it. If you receive an email receipt, save it in a dedicated folder or forward it to an app like Hey Proofy. This tool can read the shop, date, total, and items for you, and it helps by tracking warranty dates with a reminder before they end. Keeping your bills and subscriptions in one list makes it simple to search your own receipts when a problem arises. If you must keep the paper version, store it in a cool, dark, and dry place. Avoid plastic sleeves that contain chemicals which can accelerate fading. Never use heat to try and restore a faded receipt, as this will likely turn the entire paper black and destroy any remaining information. If you have already lost the details, check your bank statement or contact the retailer to see if they can look up the transaction in their system.
What to do next
-
Gather your recent receipts and take a clear photo of each one, or use Hey Proofy to upload them so the details are saved digitally.
-
Check your rights under the Consumer Guarantees Act so you know what to ask for if a product fails.
-
Set up a system to save email receipts in a dedicated folder or app, rather than leaving them buried in your inbox.
Quick answers
- Why do my receipts turn blank?
- Receipts use thermal paper that reacts to heat and light. The chemical coating on the paper continues to react over time, causing the printed text to fade until the paper is blank. This is a natural chemical process that happens regardless of how carefully you store the paper.
- Do I need the original receipt for a claim?
- No. While a receipt is the best proof of purchase, the law does not require it. You can use a bank statement, a photo of the receipt, an email confirmation, or a loyalty card record to prove you bought the item from that specific retailer.
- How long should a product last?
- There is no fixed time limit. The Consumer Guarantees Act requires goods to last a reasonable time based on their type and price. This is different from a manufacturer's warranty, which is a separate promise. Your rights under the law often extend well beyond the period stated in a store warranty.
- What if my receipt has already faded?
- If the paper is blank, you cannot restore it. Instead, use alternative proof of purchase. Check your bank or credit card statements for the transaction date and amount. Many retailers can also search their own records if you provide the date and approximate time of your purchase.
