1. Get a London pass
So you've just landed in Heathrow, it's your first time in the Queen's Country, and you want to visit absolutely everything from Westminster Abbey to the London Zoo.
Then you should consider getting a London Pass which would give you discounts on tickets to London's iconic attractions, let you skip lines, save on food and shopping, and even ride the London Tour Bus for free.
The Pass sometimes gets you access into attraction areas that are otherwise not accessible to regular visitors too.
Purchase it online prior to your trip, and get ready to see the city like a VIP at a fraction of the cost!

2. Forget the rental car
Just like in any dense and busy world city, driving from point A to B may not be the fastest - or cheapest - route. Instead, opt to use the city's many forms of public transportation.
The London Underground is great at getting you to where you need to be with minimal walking, the buses are affordable and let you see the city at a slower pace, and the "Boris" Bikes are a fun and faster alternative to walking.
You can get a London Pass that doubles up as an Oyster card for added savings. Keep your change and spend it enjoying your actual destination, not on the journey there.
3. Get cheap London theatre and musical tickets
It will be a shame to leave London without going to see a show, but while booking tickets in advance will guarantee you a seat, it could also cost as much as a small vacation to a neighbouring country.
Last minute tickets bought on the day of the performance can get you great savings at 50 per cent off the original ticket price.
Look up LastMinute.com online, the ticket counters at Leicester Square, or show up at the show venues and ask about any remaining "standing room only" tickets.
Don't be disheartened if you don't manage to get tickets to a West End play or musical; take a gander at a less-popular play - it may just be the next big hit.
4. Go big on breakfast and lunch
Breakfast and lunch in London tend to be a lot cheaper than dinner, so eat up in the morning and afternoon, and snack through the evenings on local treats found in the quaint markets or pubs.
Added bonus if you're staying at a hotel that comes with a free breakfast; all those extra savings can be easily put to good use elsewhere in London.
Pro tip: There are plenty of cheap hotels with free breakfasts to be found on Skyscanner!
