Kenko does make 2.0X and 1.4X teleconverters for the EF-S mount. They should work with the EF-S 55-250mm lens. I have never used one but they might be satisfactory to you. This would extend your effective reach on the 55-250mm to 560mm (1.4X + 1.6 camera crop) or 800mm (2.0X + 1.6 camera crop). Here are links to both:

Just keep in mind that teleconverters raise your effective aperture and can affect auto focus speed/accuracy.

Edit: Just found another brand

Interesting, I didn't realise they had actually been made for EF-S lenses.

It does seriously increase the length of my lens which would be great but I think the effect it has on the aperture and focus systems could make shooting quite difficult, even though I love trying manual focus now and then

Thank you for the links and suggestions though!

There will be no AF.  Manual focusing will be very difficult, the effective aperture at the long end will be f/11.  There will also be a very noticeable effect on the IQ.

Bare min if you want to isolate wildlife is 400mm.  Maybe look at picking up a used Canon 100-400 f/4-5.6 L - there should be plenty of first versions on the market with the II version selling well.  Even the original will be much better than the 55-250 with an extender.
