Best Supermarkets in the UK: A Guide for Expats (2026)

One of the first practical questions every expat asks after arriving in the UK is: where should I do my food shopping? The UK has a wide range of supermarkets — from budget-friendly discounters to premium retailers — and choosing the right one for your lifestyle and budget can make a real difference to your monthly spending. In this guide, we compare the main UK supermarkets, explain what makes each one unique, and tell you exactly which ones are best for expats.

Overview of UK Supermarkets

The UK supermarket market is highly competitive, with a clear hierarchy from budget to premium:

Budget Supermarkets: Aldi and Lidl

If you want to save the most money on your weekly shop, Aldi and Lidl are consistently the cheapest supermarkets in the UK. Both are German-owned discounters that have transformed the UK grocery market — and the quality has improved dramatically in recent years.

Aldi

Aldi is now one of the UK's most popular supermarkets, regularly winning awards for value and quality. Key features:

• ✅ Consistently the cheapest major supermarket in the UK
• ✅ Great quality own-brand products — many win taste awards against premium brands
• ✅ Specialbuys (middle aisle) — every week a new range of non-food products at excellent prices (kitchen gadgets, tools, clothing, sports equipment)
• ✅ Expanding rapidly — now over 1,000 stores across the UK
• ✅ Lidl Plus app for additional discounts
• ⚠️ Limited branded products — mostly own-brand
• ⚠️ Smaller stores — less variety than large supermarkets

Lidl

Very similar to Aldi in terms of price and format, Lidl has some differences that expats often prefer:

• ✅ In-store bakery — fresh bread baked daily, very popular
• ✅ Strong range of international foods — good for European expats
• ✅ Lidl Plus app — weekly digital coupons that give significant discounts
• ✅ Regular themed weeks — German week, French week, Italian week with imported products
• ✅ Slightly larger stores than Aldi in some areas

💡 Expat tip: Both Aldi and Lidl regularly stock products from European countries during themed weeks — a great way to find food from home.

Mid-Range Supermarkets: Tesco, Sainsbury's, Asda, Morrisons

Tesco — The UK's Largest Supermarket

Tesco is the UK's biggest supermarket with stores in every size — from giant Tesco Extra hypermarkets to small Tesco Express convenience stores. It's the most versatile option for expats:

• ✅ Widest range of products of any UK supermarket
• ✅ Tesco Clubcard — the UK's best loyalty card. Saves money on your weekly shop and gives access to Clubcard Prices (significant discounts for members)
• ✅ Online delivery available nationwide
• ✅ Tesco Express stores open late and on bank holidays
• ✅ Good range of international foods
• 💡 Always get a Clubcard — it's free and saves significant money

Sainsbury's

Sainsbury's is slightly more upmarket than Tesco and Asda, with a strong focus on quality and variety:

• ✅ Good quality — better than Tesco for fresh produce and meat in many stores
• ✅ Nectar Card — loyalty card that gives points and discounts
• ✅ Strong range of international and world foods
• ✅ Often located in city centres and transport hubs
• ✅ Habitat homeware section in larger stores

Asda

Owned by Walmart, Asda is one of the UK's most affordable mid-range supermarkets:

• ✅ Very competitive prices — often cheaper than Tesco and Sainsbury's
• ✅ Large stores with great variety
• ✅ Good George clothing range at very low prices
• ✅ Strong online grocery delivery service
• ⚠️ Fewer stores in city centres — more suburban/retail park locations

Morrisons

Morrisons is particularly strong on fresh food, with in-store butchers, fishmongers, and bakeries in many of its larger stores:

• ✅ Excellent fresh meat, fish, and bakery counters
• ✅ More Card loyalty program
• ✅ Good value on fresh produce
• ✅ Morrisons Market Street — fresh food sections in larger stores
• ⚠️ Fewer convenience stores than Tesco or Co-op

Premium Supermarkets: Waitrose and M&S

Waitrose

Waitrose is the UK's most prestigious mainstream supermarket — associated with quality, organic produce, and upmarket shopping. It's more expensive than other supermarkets but has a loyal following:

• ✅ Highest quality fresh produce, meat, and fish
• ✅ Excellent organic and free-range range
• ✅ Great for entertaining and dinner party food
• ✅ myWaitrose loyalty card — free newspaper or coffee with any purchase
• ⚠️ Significantly more expensive than mid-range options
• ⚠️ Fewer stores — mainly in affluent areas of the UK

Marks & Spencer Food

M&S Food is known for its exceptional quality and innovative ready meals. It's not a traditional supermarket — M&S stores stock premium M&S brand products only:

• ✅ The best ready meals in the UK — consistently top quality
• ✅ Perfect for treating yourself or impressing guests
• ✅ Excellent sandwiches and lunch options
• ✅ Sparks loyalty card gives personalised offers
• ⚠️ Only M&S products — no branded alternatives
• ⚠️ Most expensive option — not for everyday shopping

Convenience Stores: Co-op and Tesco Express

For quick shops and late-night purchases, the UK has an excellent network of convenience stores:

• Co-op — found in almost every neighbourhood, often open until 10pm or later. Co-op membership gives 5% back on Co-op brand products and 1% to local causes
• Tesco Express — small Tesco stores on high streets and petrol stations, open late
• Sainsbury's Local — similar to Tesco Express, good for city centre convenience
• Spar, Nisa, Londis — independently run convenience stores, prices higher but often open 24 hours

Loyalty Cards: Always Get These

UK supermarket loyalty cards are genuinely worth having — they give real discounts and savings:

💡 The Tesco Clubcard is the most valuable — Clubcard Prices can save you £20-40 per month on a typical family shop. Always get one as soon as you arrive.

International Food Shopping for Expats

Missing food from home? The UK has excellent options for international food shopping:

• Asian supermarkets — found in most UK cities (Wing Yip, H Mart, T&T) — excellent for Asian, South Asian and East Asian products
• Polish/Eastern European shops — very common across the UK since the 2004 EU expansion
• African and Caribbean shops — particularly in London and Birmingham
• French food — Sainsbury's and Waitrose have the best French cheese and wine selections. Aldi and Lidl run French food weeks
• Online international food — websites like Sous Chef, Ottolenghi, and Amazon UK deliver specialist ingredients nationwide

Our Recommendation for Expats

For most expats on a typical budget, we recommend this combination:

• Main weekly shop: Aldi or Lidl — save 20-30% vs mid-range supermarkets
• Top-up shop: Tesco with Clubcard — for branded products and items Aldi/Lidl don't stock
• Fresh produce: Local markets — often cheaper and fresher than supermarkets
• Treats: M&S Food or Waitrose — for special occasions and ready meals

💡 Budget tip: Switching from mid-range to budget supermarkets for your main weekly shop can save a single person £50-100 per month — that's £600-1,200 per year.
