You're lying on your back under a bath fitting a new waste trap and your phone rings. Your hands are covered in silicone. By the time you've wiped them off, the call's gone to voicemail. You ring back twenty minutes later and they've already booked someone else.
Sound familiar? If you're a plumber, you probably lose two or three jobs a week this way. Maybe more. And the worst part is you never even know about the ones who didn't leave a voicemail.
Why Missed Calls Hit Plumbers Hardest
Plumbing is reactive. Nobody plans for a burst pipe or a boiler breakdown. When someone's got water coming through the ceiling, they're ringing three plumbers and booking the first one who picks up. They're not leaving messages and waiting around.
That's the brutal truth of it. You could be the best plumber in town, but if Dave down the road answers his phone and you don't, Dave gets the job.
The Obvious Fix: Call Forwarding
Most networks let you divert unanswered calls to another number. If you've got a partner, a mate, or someone who can take a message, this works. Set it up so calls divert after three rings.
On iPhone, go to Settings → Phone → Call Forwarding. On Android, it's usually in the Phone app under Settings → Calls → Call Forwarding. Takes thirty seconds.
The problem? Whoever answers needs to know your diary, your service area, and your rates. Otherwise they're just taking a name and number — and by the time you ring back, that customer might have moved on.
Voicemail That Actually Works
If you're going to rely on voicemail, at least make it a good one. Ditch the default robot voice. Record something like:
"Hiya, you've reached [your name] Plumbing. I'm probably on a job right now but I'll ring you back within the hour. If it's urgent, drop me a text with your postcode and what's gone wrong and I'll get back to you even faster."
That text option is key. Plenty of people hate leaving voicemails but will happily fire off a text. And a text sits there waiting for you — you can read it in ten seconds between jobs.
Use a Separate Work Phone
Running your business off your personal mobile is asking for trouble. You end up ignoring calls at 9pm because it might be your mum, or answering on a Sunday because it might be a customer.
Get a cheap second phone or a dual-SIM handset. Keep your work number on it, turn it off at weekends if you want. At the very least, it means you can see at a glance whether an incoming call is work or personal.
A basic SIM-only deal is £6-8 a month. If it saves you even one job a month, it's paid for itself ten times over.
The WhatsApp Approach
More and more customers prefer messaging over calling. Especially younger homeowners. Setting up WhatsApp Business (it's free) lets people message you on your work number, and you can set up auto-replies for when you're busy.
Something like: "Thanks for your message! I'm on a job right now but I'll get back to you within 2 hours. If it's an emergency, please call [your number]."
It's not perfect, but at least the customer knows you've received their message and they're not sitting there wondering if you're ignoring them.
Virtual Assistants and Answering Services
If you're turning over decent money, a telephone answering service might be worth it. Companies like Moneypenny or alldayPA will answer your calls, take messages, and even book appointments if you give them access to your calendar. Expect to pay £50-150 a month depending on call volume.
Some plumbers now use AI assistants like Gaffer that answer calls on their behalf — taking details, checking the diary, and booking customers in. These tend to be cheaper than human answering services and work around the clock, which is handy when someone's boiler packs in at 11pm.
The Real Fix: Have a System
The plumbers who never miss work aren't superhuman — they just have a system. Whether that's call forwarding to their partner, an answering service, or an AI assistant, they've made sure someone or something is always picking up.
Sit down this weekend and work out how many calls you missed last month. Check your phone's call log. Count the ones you didn't return. Now multiply each one by your average job value — say £180 for a callout. That's what missed calls are actually costing you.
Once you see the number, you'll find a solution fast.
