How to handle peak-hour calls and improve response times

The fastest way to improve customer service response times is to make sure every call is answered live rather than sent to voicemail or left in a queue. Businesses see the biggest, most consistent improvement when they combine enough people at busy times with overflow or AI support to catch everything else, so response time stays fast whatever the volume.

Response time shapes how a customer feels about a business before a single word is said about the product or service itself. Answer quickly and consistently, and trust builds. Leave someone in a queue, or send them to voicemail, and many won't call back.

Key takeaways

• UK contact centres currently average an 8.4% call abandonment rate and a 116-second average speed to answer, both among the highest levels recorded in 20 years (ContactBabel)
• 64% of consumers now expect real-time interaction from the businesses they contact (Salesforce)
• 70% of consumers are likely to choose the business that responds to them first (Moneypenny Customer Experience Divide research)
• Peak call patterns vary significantly by sector, so managing peak hours starts with understanding your own data, not general assumptions
• A blended model of AI and human cover consistently outperforms either approach used alone for managing peak hours and out-of-hours demand

How to improve customer service response times

Response time typically slips for one of three reasons: not enough people answering at the busiest moments, no plan for calls outside core hours, or no fallback when every line is already in use. Improving it means addressing all three, not just adding more staff.

• Measure your current position first. Track how long callers wait and how many hang up before they're answered, so you know what you're improving against
• Build in overflow cover for your busiest periods, rather than sizing your team for an average day
• Give callers a route to a real person (or an AI Receptionist for routine requests) outside core hours, rather than a voicemail with no clear next step
• Review response time regularly. It tends to drift as call volumes change, so what worked six months ago may need revisiting

UK contact centres currently average a call abandonment rate of 8.4% and an average speed to answer of 116 seconds, among the highest levels recorded in 20 years of the survey (ContactBabel, UK Contact Centre Decision-Makers' Guide 2024, based on 225 UK contact centres). That gap between what's typical and what's fast is exactly where a better response time becomes a genuine advantage.

Best way to manage customer calls during peak hours

Peak hours look different for every business, but the underlying problem is the same: demand outstrips the number of people available to answer. There are a few ways to manage this without permanently over-staffing for your busiest moments.

• Identify your actual peak periods using call data, rather than assuming they match your intuition. Peaks often cluster around specific days rather than being spread evenly
• Use overflow support so extra calls are picked up by additional cover the moment your own team reaches capacity, rather than queuing or ringing out
• Let AI Receptionist absorb predictable, high-volume enquiries during peaks, freeing your team to focus on complex or high value calls
• Keep a consistent standard of answer, whether a call lands at 9am or during your busiest hour, so callers can't tell the difference

Peak patterns vary sharply by sector. Our client call data shows Mondays see 32% higher call activity than the rest of the week for property businesses, with weekend demand running at roughly 3.5 times the volume of any other day. Legal enquiries follow a different pattern again, with 44% of calls landing on Mondays and Tuesdays alone. Knowing your own pattern is the first step to managing it.

How to manage customer enquiries outside office hours

A significant share of enquiries arrive outside the traditional working day, particularly from customers who can only call in the evening or at weekends. Leaving those calls unanswered doesn't just lose the call, it often loses the customer.

• Decide what "out of hours" cover actually needs to achieve: taking a message, resolving simple requests, or handling the call in full
• Use 24/7 answering cover (people, AI Receptionist, or a blend of both) so evening and weekend callers get the same standard of response as those calling at 10am
• Route urgent, sensitive or high value out-of-hours calls to a real person, and let AI Receptionist handle routine, predictable requests such as bookings or FAQs
• Make sure whatever is captured out of hours (messages, bookings, enquiry details) flows straight into your systems, so nothing needs re-entering the next morning

64% of consumers now expect the businesses they contact to interact with them in real time (Salesforce, State of the Connected Customer). Office hours haven't caught up with that expectation, which is exactly the gap 24/7 cover is designed to close.

How to never miss important business calls

"Never missing a call" isn't really about picking up faster. It's about having a plan for every scenario that currently causes a call to go unanswered: being on another call, being out of the office, being closed for the day, or simply being at capacity during a busy spell.

• Build overflow into your setup as standard, so a second call is picked up by additional cover the moment your own line is engaged
• Extend cover to evenings, weekends and holidays, rather than treating those as periods where missed calls are simply accepted
• Make sure whoever (or whatever) answers can capture enough detail to follow up properly, rather than a caller having to repeat themselves later
• Treat a missed call as a metric worth tracking, not just an occasional inconvenience. If you can't see how many calls you're missing, you can't fix it

Our own Customer Experience Divide research found that 70% of consumers are likely to choose the business that responds to them first. A missed call doesn't just delay a conversation, it often hands that customer straight to a competitor who happened to answer.

The average cost of an inbound call now sits at £5.58, considerably more than the cost of handling the same enquiry by email or web chat (ContactBabel, UK Contact Centre Decision-Makers' Guide 2024). A missed call isn't free just because nothing was spent answering it. It's a lost opportunity that had a cost attached, even if that cost never shows up on an invoice.

Bringing it together: people, AI, or a blend of both

None of the fixes above require choosing between AI and human cover. In fact, the businesses that manage peak hours, out-of-hours calls and response time most effectively tend to blend the two: AI Receptionist for predictable, high-volume enquiries, and real people for anything that needs judgement, empathy or a more complex response. Our blended model, covered in detail on our AI and human receptionists page, is built around exactly this principle.

Frequently asked questions

• How can I improve my business's customer service response time?

Start by measuring how long callers currently wait and how many abandon the call before being answered. From there, add overflow cover for busy periods, extend coverage outside core hours, and review performance regularly, since response time tends to drift as call volumes change.

• What causes long wait times during peak hours?

Peak hours cause long wait times when the number of people answering doesn't scale with the number of calls coming in. This is usually solved with overflow support, AI handling of routine enquiries during busy periods, or a combination of both, rather than by permanently increasing headcount.

• Should out-of-hours calls go to voicemail or be answered live?

Answered live where possible. A growing share of customers expect real-time interaction regardless of the time of day, and a voicemail with no clear next step is one of the most common reasons a caller doesn't call back.

• What's the real cost of a missed business call?

There's rarely a cost on the invoice, but there is a cost in lost opportunity. UK research puts the average cost of handling an inbound call at £5.58, and separate research suggests a large majority of consumers are likely to choose whichever business responds to them first. A missed call is very often a call answered by a competitor instead.

• Is AI or a human receptionist better for handling peak-hour calls?

Both have a role. AI Receptionist is well suited to high-volume, predictable enquiries during busy periods, while a human receptionist is better placed for complex, sensitive or high value calls. Most businesses get the best result from a blend of the two, rather than relying on just one.

• How do I know if my business is missing important calls?

Track your call data: volume by hour and day, how many calls are abandoned before being answered, and how many go unanswered altogether outside core hours. Without this, missed calls are easy to underestimate because, by definition, you don't see the ones that were never answered.
