You do not need a car in London. The Tube and buses go everywhere, and central London charges a daily congestion charge.

Rent at Heathrow (LHR) or Gatwick (LGW) only for trips to the countryside. The UK drives on the left, and manual cars are cheaper than automatics.

Compare several rental sites at once. The cheapest company in London changes with your dates, so search DiscoverCars and Kayak before you book.
Book early and pick free cancellation. Rental prices usually rise close to the date, and a free cancellation booking lets you rebook if prices fall.
Compare airport and city pick-up. Picking up at LON is easiest, but offices in town can be cheaper because they skip airport fees.
Return the car with a full tank. Prepaid fuel and refueling charges at the counter cost more than filling up yourself.
Check what your credit card already covers. Many cards include rental car insurance, so you may not need the extra cover at the counter.
Bring your license and, if you can, an International Driving Permit. Outside the US many cars are manual, so filter for automatic if you need one.
