I haven't found a tab so I thought I'd post one. 
It's a simple 3 chords song but the timing is key. 
I tried to put the chords in the right places to make it easier.

Capo on the first fret, if you don't have one then the chords are:

F - F#
G - G#
Am - Bbm

INTRO
F   G   Am  F   

VERSE
                  F
What time you coming out?
     G
We started losing light
    Am
I’ll never make it right
              F
If you don’t want me round
           G
I'm so excited for the night
Am
All we needs my bike
              F
And your enormous house
      G
You said someday we might
            Am
When I'm closer to your height
                 F
Till then we'll knock around and see
           G
If you're all I need
 
CHORUS

F
   Don’t you see me now
G                      Am
   I think I’m falling, I’m falling for you
F
   Don’t you need me
G                      Am
   I think I’m falling, I’m falling for you
F
   On this night and in this light
G                      Am
   I think I’m falling, I’m falling for you
F
   Maybe you’ll change your mind
G
   I think I’m falling


VERSE
                        F
I’m caught on your coat again
      G
You said oh no, it’s fine
  Am
I read between the lines
                      F
And touched your leg again
             G
I’ll take it one day at a time
Am
Soon you will be mine
           F
Oh but I want you now
            G
When the smoke is in your eyes
Am
You look so alive
                F
Do you fancy sitting down with me


BRIDGE
                      G Am      F
Maybe ‘cos you’re all I need according to your heart
G                    Am
My place is not deliberate
F
Feeling of your arms
G
I don’t wanna be your friend, I wanna kiss your neck
 

CHORUS - Same as before

Don’t you see me
I think I’m falling, I’m falling for you
Don’t you need me
I think I’m falling, I’m falling for you
On this night and in this light
I think I’m falling, I’m falling for you
Maybe you’ll change your mind
