More than one in three estate agency proposals are being sent after a six-hour window associated with higher instruction conversion rates, according to new research from Acaboom. The study, which analysed 123,010 market appraisal proposals from UK estate agents during the first half of 2026, found that 35.9% were delivered more than six working hours after a valuation appointment.
Previous analysis by Acaboom indicated that proposals sent within six working hours are 73% more likely to convert into an instruction compared to those sent more than 24 hours later. The research also revealed that 18.2% of proposals took over two working days to arrive, with 3.9% not sent until more than five working days after the appointment.
Regional differences in response times were also identified. The North West recorded the fastest median turnaround, with proposals sent 2 hours and 41 minutes after a market appraisal. In contrast, Scotland had the slowest turnaround, with a typical proposal taking 5 hours and 21 minutes to reach prospective clients.
