That's what I thought*Edit* I've just seen your location...whatever you get make sure it's portable as there is no way you'll be able to see much from Croydon, far too much light pollution!

Try this free software - Stellarium
It's absolutely brilliant and will show you all the constellations etc., but for you right now the best feature will be the light pollution guide.
Go outside and look at the sky on a clear night, set the software to your location and change the light pollution figure until the software matches what you can see outside, that will show you what can be seen on a clear night in your area, and more importantly what you are missing.
That should help you decide whether a telescope is worth the money or not.

I have a 4K 10" Meade LX200R GPS SMT sitting in my workshop waiting for a perm mount. Stunning scope, awesome for astrophotography.
Saying that you can get decent photos of Jupiter with a £140 Celestron
