Could someone tell me if there is room on my consumer unit for an extra Circuit breaker? I intend to be adding a double oven, which requires an electrical circuit of at least 30amp, which must be isolated by means of a double pole switch.

There does seem to be a spare slot in this pic?

Thanks in advance
 
Have you got a split-load board? Ovens are normally on the non-RCD side of things as they can have quite a high earth leakage during normal use. Take a full picture of the board.
What size cable are you planning on using for your oven?
Have you planned for a DP isolator (at least 45A)?
 
Please can you take another photograph from a little bit further back to show the whole CU?
 
Here is the right hand side (main board)

Not the best quality pics (taken by phone) sorry.
 
Yes, you have two non-rcd ways and one rcd protected way.

Use one of the slots in the middle.



DISCLAIMER:
Are you aware that as you are adding a new circuit, you are legally obliged to notify your local building control of this work and pay their fee for inspection and testing? This has been the law since Jan 2005. It may be cheaper to hire an electrician, who can self certify.
 
Notice that the B16 on the Non-Rcd side for the water heater is not immediately adjacent to the main switch - usually the breakers are in descending order from the main switch, largest breaker nearest the incomer.
