A sale banner has one job: stop the passer-by and convince them today is the day to buy. Vague banners (SUMMER SALE NOW ON) get walked past. Specific banners (50% OFF EVERYTHING TODAY ONLY) get walked into.
We print sale banners for shops across London year-round. This guide covers what actually moves stock, what gets ignored, and the legal lines you cannot cross when claiming a discount.
Put a specific discount percentage in the biggest text, an end date in the middle, and the category or store name at the bottom. 50% OFF, UP TO 70% OFF, BUY ONE GET ONE FREE all outperform vague SALE banners. 510gsm PVC, 5ft x 3ft, £42 to £50 same day from Putney.
Specificity beats vagueness
SALE on a banner is shop window noise. 50% OFF is a reason to stop. The brain processes specific numbers faster than generic words because the brain is doing the work of imagining the saving.
If your average discount is 30 to 50%, write UP TO 70% OFF rather than 30 to 50% OFF. Up-to language is legally compliant if at least some items hit the headline number.
Discount levels and what they convert
10% off reads as not worth the trip. 20% off is the polite minimum. 30% off pulls casual shoppers. 50% off pulls strangers from the other side of the road. 70% off and above signals clearance, closing down or end of line.
The deadline does most of the work
A sale without a deadline is not a sale, it is a price. Add an end date in big enough type that the shopper sees a reason to act today rather than next week.
Common deadline phrases that work: TODAY ONLY, THIS WEEK, ENDS SUNDAY, UNTIL JANUARY 5, ONE WEEK ONLY. Avoid LIMITED TIME, which the brain reads as no deadline.
Sale types and the copy that suits each
Seasonal: SUMMER SALE UP TO 50% OFF ENDS AUGUST 31. Clearance: CLEARANCE EVERYTHING MUST GO. Closing down: CLOSING DOWN 70% OFF FINAL DAYS. Stock take: STOCK TAKE SALE 30% OFF THIS WEEKEND. Each format needs different copy.
Closing down banners are the strongest performers because the deadline is permanent and the discount tends to be steep. Use only when actually closing. False closing-down claims breach trading standards.
Boxing Day sale specifics
Boxing Day banners need to be up by 24 December and refresh on 27 December with revised stock. Headline the steepest discount first, then refresh to a lower discount as stock runs down. Banners that say 70% OFF when the cheapest item is at 30% off ruin trust.
SALE on a banner is shop window noise. 50% OFF is a reason to stop.
Trading Standards and discount claims
If you claim 50% off, the original price must have been the genuine selling price for at least 28 consecutive days in the six months before the sale. This is the CMA's reference pricing guidance and Trading Standards enforce it.
Up-to language (UP TO 70% OFF) is safer than blanket claims (EVERYTHING HALF PRICE) and gives the shop flexibility on stock that hits different discount tiers.

| Boxing Day | BOXING DAY 70% OFF TODAY | 70% | 26 December |
Sale banner placement and refresh cadence
Above the door, in the window, and on an A-frame at the kerb. Three banner positions cover the three customer states (across the road, walking past the window, deciding at the kerb).
Refresh the headline mid-sale to keep the message feeling current. FINAL WEEK, LAST DAYS, FINAL 48 HOURS all extend urgency without breaching trading standards.
A sale without a deadline is not a sale, it is a price.
Reuse banners across years
Print sale banners without dates and use a vinyl date sticker. The same UP TO 50% OFF banner runs every January, June and Boxing Day with a £5 to £8 sticker swap.
Roll banners on a cardboard tube between sales. Folded sale banners crease and the creases hold the colour fade that makes a sale banner look unloved.
Window vinyl SALE percentages for inside the shop
Sale banners outside pull people across the threshold. Once inside, window vinyls and shelf tags do the next layer of conversion. A simple 30% OFF EVERYTHING in the window, applied as a cling vinyl that peels off after the sale, costs £20 to £40 per metre and reuses across two or three sales.
Match the discount percentage in the window to the headline on the outside banner. Mismatched discount numbers (50% OFF on the banner, 30% OFF in the window) confuse shoppers and erode trust at the moment they were about to buy.
