Cheese and Onion and Salt and Vinegar consistently come out on top in UK crisp preference surveys. Ready Salted is the most widely bought but least often cited as a favourite. Prawn Cocktail punches above its weight. Here’s what the data and search trends actually show.
The UK takes its crisps seriously. There are more flavour options on a UK supermarket shelf than in most other countries, and the debates about which flavour is best are genuinely heated. This isn’t a piece saying one flavour is objectively correct. It’s a look at what the evidence shows about what people actually prefer and buy most.
The Top UK Crisp Flavours by Popularity
Cheese and Onion
Cheese and Onion consistently comes out as the top-ranked crisp flavour in UK consumer surveys. It’s been this way for decades. The combination of sharp cheese flavour and the slight edge of onion is a balance that works at scale: liked by a wide range of people, rarely anyone’s least favourite.
There’s also a regional dimension. In the north of England, Cheese and Onion tends to come in a blue packet. In the south, blue packets often mean Salt and Vinegar. This has been a point of low-level national argument for as long as people have bothered to argue about it.
Salt and Vinegar
Salt and Vinegar is the UK’s most divisive popular flavour. People who love it really love it. People who don’t are fairly firm about that. Despite this division, it consistently finishes second or joint first in preference polls and is one of the top-selling flavours by volume across all major brands.
Walkers Salt and Vinegar is notable for coming in a green packet, which also generates its share of debate. The article on why Walkers salt and vinegar bags are green goes into the full story behind the colour coding.
Ready Salted
Ready Salted is the most widely purchased flavour in the UK, consistently. It’s also the one people are least likely to cite as their “favourite.” It’s bought because it’s the safe choice, the one that everyone will eat, the flavour with no objectors. That’s not a criticism. It’s a genuinely useful property.
Plain Walkers Ready Salted is available in bulk here.
Prawn Cocktail
Prawn Cocktail consistently outperforms its ranking in sales surveys when you look at the passion of its fans. It’s not always the third-biggest seller by volume, but people who love it are particularly committed to it. It’s also genuinely unusual in the global crisp market: the prawn cocktail flavour is very much a British thing.
Our full breakdown of prawn cocktail crisps covers what actually goes into the flavour and which brands do it best.
Regional Variations in Favourite Flavours
North vs South
The north-south divide in crisp flavour preferences is real but often overstated. The main genuine difference is in packet colour associations (the blue packet issue above), but actual flavour preference data doesn’t show a dramatic regional split. Cheese and Onion and Salt and Vinegar both perform well nationally.
Younger vs Older Preferences
Data from search trends and consumer surveys suggests younger people lean toward bolder flavours (Flamin’ Hot, Paprika, Chilli) while older consumers skew toward the classics. This tracks with how the UK crisp market has changed: flavour innovation has accelerated, and the new entries tend to target younger buyers.
Monster Munch Flamin’ Hot and similar products have benefited from this trend.
How Search Data Shows What People Actually Think About
What Google Searches Tell Us
Search data from UK users reveals some interesting patterns. “Are crisps healthier than chocolate” is one of the most searched crisp-related questions, suggesting people are genuinely thinking about crisp consumption in a health context. “What are the UK’s favourite crisps” gets tens of thousands of searches a year, which is exactly why this post exists.
Searches for specific brands (Walkers, Monster Munch, Nik Naks, Hula Hoops) consistently appear alongside searches for specific flavour variations, which suggests people are interested in options within brands they already trust rather than entirely new products.
The Data on Unusual Flavours
Some flavour-specific searches are very high volume for what seem like niche questions. “Are skips vegan” gets thousands of monthly searches. “Are hula hoops gluten free” is searched for constantly. This tells you that people are making decisions based on dietary requirements as much as flavour preference, and that the crisp market needs to serve those needs more visibly.
The Best-Selling Crisp Brands in the UK
Walkers
Walkers is the dominant UK crisp brand by market share, and has been since the 1980s. The Cheese and Onion, Salt and Vinegar, and Ready Salted core range accounts for a large proportion of UK crisp sales. The brand is owned by PepsiCo, as is the US equivalent Lays. More on how Walkers and Lays are connected here.
KP Snacks
KP is the second force in the UK market, with a portfolio including Hula Hoops, McCoy’s, Nik Naks, and Wheat Crunchies. Their strength is in the category adjacent to traditional crisps: corn snacks, extruded snacks, and products with more texture variation than a standard flat crisp.
Golden Wonder
Golden Wonder is the third-place brand nationally and the one most associated with regional loyalty. It remains genuinely popular in Scotland in particular. The brand’s continued existence surprises some people. The Golden Wonder story in full is more interesting than most people expect.
The Real Favourite: It Depends Who You Ask
The “UK’s favourite crisp” doesn’t have one answer because the data produces different answers depending on what you measure. Sales volume gives you Ready Salted. Preference surveys give you Cheese and Onion. Brand loyalty metrics give you Walkers. Passion per fan might give you something like Space Raiders or Nik Naks.
Space Raiders and Discos both have loyal followings that punch well above their sales numbers in terms of enthusiasm. That counts for something too.

Whatever comes out top for you personally, One Pound Crisps stocks the full range at bulk prices. From the Walkers classics to the more specialist KP brands, buying by the box is always better value.
What is the UK’s favourite crisp flavour?
Cheese and Onion consistently comes out on top in UK consumer preference surveys, followed closely by Salt and Vinegar. Ready Salted is the most widely purchased by volume but is rarely cited as anyone’s first choice. Prawn Cocktail has a particularly passionate fanbase relative to its market share.
What is the best-selling crisp in the UK?
Walkers is the best-selling crisp brand by market share. Within flavours, Ready Salted is typically the highest-volume seller because it has the broadest appeal and fewest objectors, making it the default choice for shared settings.
Why do crisp packet colours mean different things in different parts of the UK?
Historically, different manufacturers used different colour coding for their flavours, and the conventions were established independently in different regions. The most famous example is the blue packet: in the north of England, blue typically means Cheese and Onion, while in the south it often means Salt and Vinegar. Walkers uses blue for Cheese and Onion, which is now the most common national standard.
What crisp flavours are unique to the UK?
Prawn Cocktail is one of the most distinctly British crisp flavours and is rarely found in other markets. Worcestershire Sauce flavour is another UK-specific option. The range and variety of flavours available in the UK is broader than most other countries, partly due to the strong culture around crisps as a snack category.
Are Walkers crisps the most popular in the UK?
Yes. Walkers is the largest crisp brand in the UK by market share and has been the market leader since the 1980s. The brand is owned by PepsiCo, which also owns Lays internationally. The core Walkers flavours (Cheese and Onion, Salt and Vinegar, Ready Salted) account for a significant proportion of all UK crisp sales.
What are the most searched-for crisp brands in the UK?
Walkers generates the most search volume overall. Monster Munch, Nik Naks, Hula Hoops, and Space Raiders all have strong search presence relative to their market size, reflecting passionate fanbases. Searches for dietary information (vegan, gluten free) around specific crisp brands are also very high in volume.
