Unless you have set something up, calls outside office hours usually ring out, go to a basic voicemail, or reach a mobile you may not answer. A better approach is to divert your line to a service that answers live during business hours and captures after-hours callers on voicemail, so every enquiry is waiting for you the next working day.
Your office door closes at the end of the day, but your phone number does not. Customers ring in the evening after work, at weekends and on bank holidays. What happens to those calls depends entirely on how your phone line is set up, and plenty of businesses have never checked.
This guide explains where after-hours calls usually end up, the realistic options for handling them, and how to put a sensible plan in place without paying for cover you do not need.
The default: out-of-hours calls often go nowhere useful
If you have not set anything up, an out-of-hours call usually does one of three things. It rings out, it goes to a generic voicemail, or it goes to a mobile that you may or may not answer at the dinner table.
None of these is ideal. Unanswered calls can end up with competitors, and voicemail is often ignored, with many callers hanging up rather than leaving a message. IntroducerTODAY has estimated that missed calls cost UK businesses around £30 billion a year, about £5,500 per business. It is a widely quoted industry estimate rather than an official statistic, but it shows why missed calls matter. To see whether this applies to you, read how to tell if your business is losing money from missed calls.
Your main options for calls after hours
There is no single right answer. The best choice depends on who rings you, how urgent their calls tend to be, and how much of your evening you want to protect.
| Option | What the caller experiences | Things to consider |
|---|---|---|
| Let it ring out | No answer and no way to leave details | Callers may simply try the next business on their list |
| Basic voicemail on your own line | A standard greeting and a beep | You have to check it, and many callers will not leave a message |
| Divert to your personal mobile | You answer, if you can | Blurs work and home life, and calls are still missed |
| Voicemail attached through an answering service | Their call is picked up and they can leave their details | Messages are captured for the next working day |
| Live answering outside business hours | A person answers | Hours of cover vary by provider, and some add out-of-hours surcharges |
How Onwards Answering handles calls outside business hours
We like to be clear about what we do and do not offer. Our receptionists answer calls live within business hours. Outside standard working hours, you can attach a voicemail service to your business number. That round-the-clock voicemail is included in your package and is not charged as an extra.
In practice, that gives you two layers of cover. During the day, a real person answers in your company name, takes messages, transfers calls and books appointments. After hours, callers can still leave their details rather than hearing a phone ring out, and you can pick up those messages when you are back at work.
If after-hours calls are currently landing on your personal phone, our optional secure Business Number can also help you keep work and personal calls separate. Our guide on keeping your existing business number explains how numbers work when you start with an answering service.
Setting up scheduled diverts
Most after-hours plans rely on a divert. The main types are:
- All calls: everything goes to the answering service, which suits full cover.
- No answer: calls divert if nobody picks up within a set time.
- Busy or engaged: calls divert when your line is already in use.
- Scheduled: diverts switch on automatically at set times, such as lunchtimes or after hours.
Cloud and VoIP phone systems usually have divert or forwarding rules in their app or admin portal, which makes scheduled diverts easy to manage. On a BT line, call diversion is an added feature: you divert all calls by pressing *21*, then the number to divert to, then #, and cancel with #21#. BT Business explains the codes in full, and notes that the diverted leg of the call is charged at standard dialling rates. For every method, including mobiles, see our guide on how to divert your business calls to an answering service.
Businesses that should think hardest about after-hours calls
Every business misses some calls after closing, but for some the impact is bigger:
- Trades and construction: customers often ring in the evening once they are home and have noticed a problem. See our call handling for construction firms and trades.
- Letting and estate agents: tenants, landlords and buyers frequently call after their own working day ends.
- Clinics and health practices: patients may want to book, cancel or ask a question outside appointment hours.
- Small professional firms: a new client choosing between several providers may only have time to ring in the evening.
A quick checklist for your after-hours plan
- Look at your phone system's call logs to see when calls arrive and how many are missed.
- Decide what counts as urgent for your business, and what can wait until the morning.
- Choose where calls go after hours: voicemail, a mobile, or a mix for different situations.
- Make sure callers know their message has been received and when they can expect to hear back.
- Agree who checks messages each morning and how quickly they respond.

Frequently asked questions
Do call answering services answer calls around the clock?
It depends on the provider. Hours of cover are one of the main things that affect price, and some providers add out-of-hours surcharges. Onwards Answering answers calls live within business hours and includes round-the-clock voicemail at no extra charge, so after-hours callers can still leave their details.
Should I divert out-of-hours calls to my mobile?
You can, but it blurs the line between work and home, and you will still miss calls when you are busy or asleep. Many owners prefer to divert to an answering service during the day and let voicemail capture after-hours callers, then return those calls the next working day.
Will I pay extra for calls outside office hours?
With Onwards Answering, after-hours voicemail is included and there are no per-call charges. Other providers may work differently, so check for out-of-hours surcharges, set-up fees and minimum contract terms before you sign. Our pricing guides explain the common models in more detail.
