London can be an expensive city to explore. Between observation decks, exhibitions, guided tours, river cruises and famous attractions, it doesn't take long for a sightseeing budget to disappear.
And sometimes, you simply don't want to spend £25 or £30 every time you decide to visit somewhere.
But here's something worth knowing: you don't actually need to pay for an attraction ticket to have a brilliant day in London. Some of the city's most interesting museums have free permanent collections, some of its best viewpoints don't charge admission, and there are beautiful parks, historic streets and riverside spaces where you can spend hours without buying a ticket.
You could spend the morning looking at world-famous paintings, walk through a former power station, admire the London skyline from a skyscraper or explore one of the capital's historic parks. There is plenty to do without making every stop a paid experience.
The trick is knowing where to go.
So, if you're visiting London on a budget, or simply don't fancy spending money on attractions every time you head out, here are 14 places worth adding to your plans.
1. British Museum – Explore thousands of years of world history
If you want to spend several hours somewhere without paying an admission fee, the British Museum is an excellent place to begin.
Located in Bloomsbury, the museum takes you through different civilisations, cultures and periods of human history. Its permanent collection includes objects from ancient Egypt, Greece, Rome, Asia, Africa and the Americas.
You can see famous objects such as the Rosetta Stone, Egyptian mummies and the Parthenon sculptures. The museum's Great Court is also worth visiting, even if you aren't planning to spend hours exploring every gallery.
One of the best things about the British Museum is that you don't need to be an expert in history to enjoy it. You can choose a few galleries that interest you, wander around at your own pace and discover things you didn't know existed.
You could easily spend half a day here without feeling that you need to rush.
Why visit: World-famous historical objects, impressive architecture and enough free galleries to fill several hours.
Location: Great Russell Street, Bloomsbury, WC1B 3DG.

You don't have to buy a ticket to experience one of London's most recognisable museums.
The Natural History Museum in South Kensington is one of the best places to visit when you want an interesting day out without spending money on admission.
The building itself is impressive, but the real attraction is what you find inside. Its galleries explore the natural world, from prehistoric creatures and fossils to minerals, mammals, volcanoes and the history of life on Earth.
The dinosaur galleries are particularly popular, especially with families. You can also visit Hintze Hall, where the enormous blue whale skeleton hangs above visitors.
Outside, the museum's gardens offer another reason to spend time in the area.
The museum is large enough to keep you occupied for a couple of hours, and you can choose your own route rather than following a fixed tour.
Why visit: Dinosaurs, fossils, natural history and one of London's most impressive museum interiors.
Location: Cromwell Road, South Kensington, SW7 5BD.
Budget tip: General gallery admission is free. The museum recommends booking a free entry ticket to help guarantee entry and avoid queues. Some exhibitions and special experiences are paid separately.
3. Victoria and Albert Museum – A free day out for art, fashion and design lovers
If you enjoy architecture, fashion, jewellery, sculpture or decorative arts, the V&A is one of the most rewarding places to visit in London.
Situated in South Kensington, the museum houses an enormous collection covering thousands of years of human creativity.
You can explore historic clothing, furniture, ceramics, jewellery, sculptures and objects from different cultures. Its Cast Courts are particularly impressive, with large-scale reproductions of famous sculptures and architectural details.

You don't need to understand every artistic movement to enjoy the museum. Even a relaxed walk through a handful of galleries can be a memorable experience.
The V&A also makes a convenient stop if you're planning to visit the Natural History Museum or Science Museum on the same day.
Why visit: Fashion, design, sculpture, beautiful interiors and a huge collection to explore.

You don't have to pay for a ticket to enjoy one of London's most distinctive cultural buildings.
Tate Modern occupies the former Bankside Power Station on the south bank of the Thames. Its industrial architecture, enormous spaces and riverside location make it an interesting place to visit even before you begin looking at the artwork.
Inside, you'll find a collection of modern and contemporary art, with works by internationally recognised artists and changing displays.
The Turbine Hall is one of the building's most memorable spaces. Its enormous scale makes it feel completely different from a traditional art gallery.
You can also enjoy views of the surrounding city from the museum's public areas. It is a particularly good stop if you're already walking along the South Bank.
Some temporary exhibitions are ticketed, but you can still explore the free collection and enjoy the building without buying an exhibition ticket.

6. National Portrait Gallery – Discover the faces behind British history
Just around the corner from Trafalgar Square, the National Portrait Gallery is another excellent free place to visit.
Instead of focusing on landscapes, sculptures or decorative arts, this gallery tells stories through portraits of people who have shaped British history and culture.
Its collection includes portraits of monarchs, writers, musicians, politicians, artists and other notable figures.
It is an interesting way to explore history because the people are often familiar, even if you don't recognise every name. You might find yourself looking at portraits of historical figures you've studied, musicians you listen to or people whose work has influenced modern Britain.
The gallery's recently renewed spaces also make it a pleasant place to spend time.

If you're interested in history, the Imperial War Museum in Lambeth is well worth visiting.

Greenwich is one of the best areas in London for a day out without spending money on major attractions.
The National Maritime Museum is free to enter and explores Britain's maritime history through exhibitions, collections and objects connected to the sea, exploration and naval life.
A short walk away is the Queen's House, a historic royal building known for its architecture and art collection.
The Queen's House is particularly interesting because of its elegant interiors, distinctive design and famous Armada Portrait of Elizabeth I.
Both places are part of Royal Museums Greenwich, which makes it easy to visit them together.
Afterwards, you can walk through Greenwich Park, explore the streets around the market or simply enjoy the views across the river.
One thing to remember: the nearby Cutty Sark and Royal Observatory are separate paid attractions. You can enjoy Greenwich without buying tickets for either.

9. Wallace Collection – Discover an impressive historic art collection
If you want to visit a museum that feels a little different from London's larger institutions, consider the Wallace Collection.
Located inside Hertford House near Manchester Square, this museum is home to European paintings, sculptures, decorative arts, furniture, porcelain and an extensive collection of arms and armour.
The interiors are part of the experience. Rather than feeling like a huge modern exhibition space, the collection is displayed across historic rooms that give the building a distinctive atmosphere.

It is also a good option if you're exploring Marylebone or shopping around Oxford Street and Bond Street.

If you're looking for something that feels more like a traditional London attraction, Sky Garden is a particularly good option.

From inside, you can look out towards landmarks such as the Shard, Tower Bridge, St Paul's Cathedral and the River Thames.
The tropical planting gives the space a different atmosphere from a conventional observation deck. You can wander around, enjoy the views and take photographs without paying an admission fee.
The important thing is to plan ahead.

Another brilliant option for free city views is Horizon 22 at 22 Bishopsgate.
The viewing gallery is one of London's highest free-to-access public viewpoints, giving visitors a wide panorama of the capital.
From up there, you can spot famous buildings, the Thames and many of London's familiar landmarks. It is a particularly good place to visit if you enjoy photography or want to understand how the city's different neighbourhoods fit together.

12. South Bank – Enjoy a London day out along the Thames
You don't need to buy a ticket for the London Eye or a river cruise to enjoy one of London's most recognisable riverside areas.
The South Bank is one of the best places to explore when you want to spend a few hours outside without paying for an attraction.
Start around Westminster Bridge and walk along the river towards the Southbank Centre and Tate Modern. Along the way, you'll pass famous landmarks, public art, riverside seating areas and plenty of places to stop for photographs.
The Queen's Walk is particularly enjoyable, with views towards the Houses of Parliament, the London Eye and St Paul's Cathedral.
You can also visit Leake Street Arches, a graffiti-covered tunnel near Waterloo where the artwork changes regularly.
Street performers, public spaces and the general atmosphere make this area interesting even if you don't spend a penny.
The Southbank Centre is free to enter, and more than half of its events are listed as free, although individual performances and exhibitions may require tickets.
Why visit: Riverside views, street art, public spaces, performances and a lively London atmosphere.

13. Greenwich Park – Enjoy one of London's most beautiful free views
Greenwich Park is a wonderful choice when you want to spend time outdoors.
It is one of London's Royal Parks and offers a mixture of open green spaces, historic surroundings, tree-lined paths and elevated viewpoints.
The walk towards the hill above the Royal Observatory is particularly rewarding. From the top, you can enjoy one of London's most recognisable views, looking across the Old Royal Naval College towards Canary Wharf and the Thames.
You can also explore the park's gardens, relax on the grass, take photographs or simply enjoy a slower afternoon away from the busiest parts of central London.
Greenwich itself is worth exploring too. The surrounding streets, riverside and historic architecture make it easy to spend a whole day in the area without buying attraction tickets.
Why visit: Beautiful scenery, historic surroundings, open green spaces and an iconic London skyline view.
Location: Greenwich, SE10 8QY.
Budget tip: Entry to the park is free. The Royal Observatory and Cutty Sark are separate paid attractions, so you can simply enjoy the park and its views without entering them.
14. Hampstead Heath and Parliament Hill – Find one of London's best skyline views
If you want to get away from the busy streets of central London, Hampstead Heath is a brilliant place to spend an afternoon.
Unlike some of the more formally landscaped parks, the Heath has a wilder character. There are woodland paths, open grassland, ponds and large areas where you can walk without feeling surrounded by the city.
One of its biggest attractions is Parliament Hill.
The viewpoint gives you a wide view across London's skyline, with the city's buildings stretching out in the distance. On a clear day, it's a fantastic place to take photographs or simply sit and enjoy the view.
It is especially lovely around sunset, when the light changes across the city.
You can also explore the surrounding Hampstead neighbourhood, with its historic streets, independent shops and traditional pubs. Just remember that stopping for food or drinks is an optional extra.
Why visit: Open countryside-like scenery, walking routes, nature and one of London's best free skyline views.
Location: Parliament Hill, Hampstead Heath, NW5 1QR.
Budget tip: The Heath and its public viewpoints are free to enjoy. Bring your own water and a picnic if you want to keep the day inexpensive.
How to enjoy London without spending money on attractions
The best way to explore London on a budget is to combine places that are close to each other. Rather than travelling across the city for one free museum, build a day around a neighbourhood.
Here are a few combinations worth trying.
South Kensington day: Visit the Natural History Museum and V&A. Both have free permanent galleries, and you can spend a good part of the day exploring them.
Trafalgar Square and the West End: Visit the National Gallery and National Portrait Gallery, then walk through Leicester Square, Covent Garden and Soho.
Greenwich day: Explore the National Maritime Museum, Queen's House and Greenwich Park. Finish with a walk through the historic centre and along the riverside.
City of London day: Book a free Sky Garden visit or Horizon 22, then explore Leadenhall Market and the surrounding historic streets.
South Bank day: Walk along the Thames, explore the Southbank Centre, visit Tate Modern and discover Leake Street's street art.
These combinations help you spend more time exploring and less time travelling between destinations.
A few things to remember before visiting
Free admission does not mean every experience is free: Temporary exhibitions, special events, guided experiences and interactive attractions can carry separate charges.
Book popular viewpoints in advance: Sky Garden has limited free timed-entry tickets, while Horizon 22 also operates a ticketing system.
Check opening times: Museums and galleries sometimes close individual rooms or change their schedules.
Don't forget transport costs: A free attraction can still involve a Tube or bus journey. Walking between nearby places can save money.
Bring your own refreshments: Cafés and restaurants inside attractions can quickly increase the cost of a day out.
Check seasonal access: Gardens, outdoor spaces and rooftop areas may have different opening arrangements depending on the time of year.
Final thoughts
You don't have to spend money on expensive attractions every time you visit London.
Some of the best experiences in the capital are surprisingly accessible. You can stand in front of famous paintings, explore ancient history, admire the skyline from a skyscraper, walk beside the Thames or spend an afternoon in a beautiful park without paying an admission fee.
If you're visiting London for the first time, the British Museum, Natural History Museum, South Bank and Greenwich are excellent places to begin. If you've already explored the main tourist attractions, try the Wallace Collection, Horizon 22 or Hampstead Heath for something a little different.
And perhaps that's one of the nicest things about London: you can have a memorable day in the city without constantly reaching for your wallet.
