Requirement for full versus partial translation of rental contract for UK visa

Hi everyone, I am currently preparing my documents for a UK tourist visa application. I have a housing rental contract to submit as proof of accommodation, but the original document is over 12 pages long.

Is there a specific requirement stating that I must translate the full document word-for-word? Or is it acceptable to provide a translation of only the relevant pages containing key information like the contact details, dates, and signatures? I would prefer to avoid the high cost of a full translation if a partial one is sufficient.
