UK, Ireland / Applying for a social housing in the UK - translation of a birth certificate? [2]

Hi there.
I just wondered if anyone here had applied for a social housing in UK? i am in a process and was told that I have to bring a birth certificate. Done that. But it's in Polish.

The embassy does only translations from English into Polish (yeah, I know that's silly), so my question is: do I have to get that birth certificate translated, and if yes, where/who can do that? (so the council accepts the translated copy?)

any advise- thanks a lot.
