GNU Aspell has an en_GB-ize-w_accents dictionary, which I think is what's needed. The source seems to be here: http://wordlist.aspell.net/ http://wordlist.aspell.net/ It's the UN's official version of English [1], and my employer's, and it's widely used in scientific publications. I'd like to use it in Firefox, but the British dictionary extension[2] accepts both versions. I have "feces colored airplane modeling" marked as misspellings, and "digitized aeroplane signalling" accepted, but "digitised" is also accepted by this dictionary.
