Old Photo...any ideas on date or age of sitters?

Hi
This is a photo from a box of stuff of my parents.
I have absolutely no idea who the people in the picture are.
Would anyone like to guess the roundabout date it would have been taken and/or judge the approx ages of the sitters?
The reverse of the photo is printed so that it could be sent as a postcard but is otherwise blank.
This made me think it was a studio photograph but the quality is really not that good!
Do the clothes give any idea of status or  geographical location ?
I'm pretty sure it must have been taken in the UK.
Any ideas welcome
Thanks
Rebel

GUESS at UK 1920's /1930's BUT ONLY a guess:

I was going to say 1920’s.  I have a wedding group photo from 1925 and the gentleman reminded me of that. 

They look to be getting on in age, 70 ish give or take.

Many thanks for the clean up and sharpening of the photo!
Yes, the original really is that bad....
One side of my family originates in Devon, the other WRY, they collided in London in the 1890s but I guess a photo with no names or location noted is of no use at all!
Perhaps a Rootschatter may one day identify them..
Cheers
