A weekly travelcard for Zones 1 - 2 increases from £32.40 to £33.00 A paper one day off peak travelcard increases from £12.10 to £12.30 Oyster PAYG fares for tube and bus remain frozen.
Weekly and Monthly Travelcards are available for zones excluding zone 1 (central London). So if you’re working, studying or visiting relatives in the suburbs of London, you don’t need a Travelcard including zone 1 unless you travel through zone 1 to reach your destination or enter or exit a station in zone 1.
A monthly Travelcard for zones 1 through 4 (Eltham is in zone 4) will cost £121.40. You'll need to ensure you get a paper Travelcard, as Oyster cards aren't used on most overground (National Rail) services - supposed to be coming soon, but in the interim, the paper Travelcard will work.
