The UK Enquiry Response Gap
We sent 21 written enquiries to UK estate agents, dental practices and mortgage brokers, on a Saturday afternoon and a Thursday evening, and timed every first human reply. The same businesses that answered a weekday-evening enquiry within the half hour took the whole weekend to answer a Saturday one. And the only two that never replied were the two whose websites promised they were always on.
Anonymised: no business is named, results are reported at vertical and town level only.
One enquiry per business, two time windows
We sent one realistic written enquiry per business through its own website: a valuation request to estate agents, a new-patient enquiry to dental practices, a remortgage enquiry to mortgage brokers. The sample was 21 UK independents and one multi-branch chain comparator: 7 estate agents, 9 dental practices and 5 mortgage brokers.
Window one went out on Saturday 24 October 2026, 2:00pm to 3:30pm (11 enquiries). Window two went out on Thursday 29 October 2026, 6:37pm to 6:55pm (10 enquiries), after stated closing times. We timed the first human reply on any channel, and we withdrew politely the moment any business asked to proceed: no appointments held beyond hours, no staff time wasted. Each business privately received its own result.
Saturday-window replies were verified as human via email headers. Thursday-window send times were reconstructed from timestamped submission records and validated to the minute against two platform auto-acknowledgements. Figures we could not fix to the minute are given as ranges.
Six things the data showed
Everyone replies. The weekend decides who replies first.
19 of 21 businesses replied, so UK independents do follow up. The same verticals that took 42 to 46 hours to answer a Saturday-afternoon enquiry answered a Thursday-evening one in 13 to 51 minutes, after stated closing times, from personal phones. Dentists who were silent all weekend in the first window replied by 9:38 the next morning in the second. The gap is not effort. It is a blind spot, and it sits on Saturday and Sunday, exactly when an enquirer is comparing two or three firms and will proceed with whoever answers first.
The fastest reply came from a mortgage broker, after hours, from a phone.
The quickest first human reply of all 21 arrived 13 to 14 minutes after a 6:45pm enquiry, an hour after the firm's stated closing time. Three of the four same-evening repliers were owners or named advisers answering personally. Speed in this test was not a staffing function. It was individuals who treat an evening enquiry as live.
The two silent businesses were the two that promised to be always on.
One ran an AI receptionist on the very page the enquiry went through. The other was a multi-branch chain advertising staffing until 9pm, open at the moment the enquiry arrived, and silent through the staffed Saturday that followed. Both captured the enquiry instantly. Neither ever replied. Every independent in the sample did.
Capture is not follow-up.
Of the chat or AI-fronted sites tested, one produced a same-day human reply that re-asked nine questions the assistant had already collected, one followed up the first business morning, one took around four days on a different channel, and one never replied at all. Separately, one capture platform kept auto-nurturing the lead by email five days after the firm's humans had closed the thread, and the chain that never replied added the enquirer to its weekly marketing newsletter. Six days on, the enquiry had become a Dear Valued Customer but never a conversation.
Written enquiries get dragged to the phone.
Across both windows, 8 of the 19 repliers phoned first, phoned instead, or made a call the required next step, and several more pushed booking to a phone line. Three of the ten weekday-evening forms gave a written enquiry no written way back: no email-reply option, verbal-contact terms, or no message box at all. The person filling in a form at 2pm on a Saturday or 6:45pm on a Thursday chose a form for a reason. One dental practice bucked the trend and replied by WhatsApp within half an hour.
Late replies were good replies. They were just second.
The slowest reply took around four days and switched channels twice, yet was the most complete dental answer of the whole test: real pricing, concrete dates, a named person. Nobody lost the lead by ignoring it. They lost it by being second.
How this compares with other studies
Other recent UK studies have measured parts of this picture, at larger scale and in a single vertical. They are worth reading alongside this one.
154 enquiries to estate agency branches in London, Birmingham and Newcastle. Median time to first human contact was 5 hours 13 minutes for out-of-hours seller valuation requests, 33 of 35 evening requests got no same-evening human reply, and none of the 154 enquiries received a WhatsApp message.
Rang UK sales and letting agencies on weekday evenings (6pm to 9pm) and found 94.1% of calls went unanswered, as reported by Property Industry Eye.
Found an average response of 229 business minutes to estate agency sales enquiries.
What this study adds is the parts those tests did not cover: the same enquiry design run across three verticals rather than one, a direct weekend versus weekday-evening comparison within the same businesses, and what happens after capture, from auto-replies that promise nothing to marketing sequences that keep running after the enquiry has died. It is also, at 21 businesses, deliberately small: one enquiry each, fully withdrawn, with each business given its own result privately.
Frequently asked questions
How quickly do UK small businesses reply to a written enquiry?
It depends on the day, far more than the hour. In this test, enquiries sent on a Thursday evening after stated closing times got first human replies in 13 to 51 minutes from the businesses that answered the same evening. The same verticals took 42 to 46 hours to answer a Saturday-afternoon enquiry, first replying on Monday. Overall 19 of 21 businesses replied before cut-off.
Is the gap evenings or weekends?
The weekend. Dentists and brokers who stayed silent all weekend in the Saturday window replied to a weekday-evening enquiry within minutes, personally, after closing, from their own phones. The fastest reply of all 21 came from a mortgage broker 13 to 14 minutes after a 6:45pm enquiry, an hour after the firm's stated closing time.
Do estate agents respond faster than dentists and mortgage brokers?
On a Saturday, yes: estate agents in this test answered the same afternoon in 29 minutes to 2 hours 10 minutes, while dentists and brokers first replied on Monday, 42 to 46 hours later. On a weekday evening the difference disappeared: all three verticals produced fast repliers, and the single fastest was a broker.
Does an AI receptionist or website chatbot mean faster replies?
Not in this test. The only two businesses that never replied at all were the two with the strongest always-on stories on their own websites: a practice running an AI receptionist on the very page the enquiry went through, and a multi-branch chain advertising staffing until 9pm, which was open at the moment the enquiry arrived. Capture tools answered instantly; the follow-up never came. Every independent replied.
What happens to a written enquiry after the auto-reply?
Often, marketing rather than conversation. One capture platform kept auto-nurturing the enquirer by email five days after the firm's humans had closed the thread. The chain that never replied added the enquirer to its weekly marketing newsletter: six days on, the enquiry had become a Dear Valued Customer but never a conversation. One practice's own auto-confirmation landed in the enquirer's spam folder, so its we-will-be-in-touch was never seen.
Do businesses reply in writing or by phone?
Mostly they reach for the phone. Of the 19 repliers, 8 phoned first, phoned instead, or made a call the required next step, and several more pushed booking to a phone line. Three of the ten weekday-evening forms gave a written enquiry no written way back at all. One dental practice replied by WhatsApp within half an hour of an evening enquiry, the exception that shows it can be done.

Read before citing
- The sample is small by design: 21 businesses, one enquiry each. It describes these businesses in these two weeks, not every UK firm. Differences of minutes are not meaningful; the weekend-versus- evening pattern is the finding.
- The two windows differ by day and time, which is the point of the design, but it means vertical comparisons within a single window are more reliable than comparisons across windows.
- A reply meant a real person on any channel: email, phone call, text or WhatsApp. Auto-replies and templated confirmations were logged separately and did not count.
- Approximate figures are shown as ranges; exact clocks are stated where we hold them.
- Our interest, stated plainly: Cognumi runs managed enquiry handling for UK service businesses, which is the gap this test measures. The method is published so the results can be checked, and no business tested was approached as a sales prospect through this research without first receiving its own result.
