British academic English is a specific register. Markers can spot non-native or non-academic prose within a paragraph, and it costs marks even when the argument is sound.
Hedging
UK academic writing hedges claims. 'This suggests', 'it appears that', 'one possible interpretation is', these phrases acknowledge uncertainty and signal intellectual sophistication. Unhedged claims read as overconfident.
Formality
No contractions (don't, can't, won't). No first person in most disciplines (use 'this study' or 'the analysis'). No colloquialisms. No rhetorical questions.
British spelling
Behaviour, organisation, analyse, programme, colour, centre. Set your Word document to UK English and stick to it throughout.
Signposting
Use connectives to guide the reader: 'however', 'in contrast', 'building on this', 'a further consideration'. Avoid 'firstly, secondly, thirdly' lists, they read as schoolwork.
