Should a small business have a separate phone number?
Often, yes. A number that is only for work lets you set a proper greeting, switch off in the evening without missing a customer, and hand the phone to someone else later. The number matters less than what happens when it rings and nobody answers.

01
What a separate number gives you
- A greeting that is about the business, not a personal voicemail.
- Time off that is real, because the work phone can be put down.
- A number that stays the same if you change phone or hand calls to someone else.
- A clear list of work calls, so none sit among personal ones.
02
What it does not fix
A new number does not answer itself. If a caller reaches it while you are on a job, they still need to hear something useful and be able to leave details easily. A separate number makes that easier to set up, but you still have to set it up.
03
Before you change the number on everything
Your number is probably on vans, cards, listings and old quotes. Changing it means customers who ring the old one hear nothing. If you move, keep the old number working for a while, and update your Google Business Profile and website first.
04
Check what you already have
Some providers let one phone carry two numbers, or forward a work number to your mobile at set times. Ask your provider what is on offer before buying anything new.
05
If you would rather not carry a second phone
A work number that texts back every missed caller automatically can sit alongside the phone you already have. We can talk through whether that suits you on a free 20-minute call, and say honestly if the simpler route will do.
