Winter call surge: a plan for plumbers and heating engineers

The best way to handle winter emergency calls as a plumber or heating engineer is to write your plan before the first cold snap: decide what counts as an emergency, set up cover for the calls you can't answer, and prepare short replies that tell callers what to do safely while they wait. Then check your phone settings so new customers aren't silently sent to voicemail.

Why does winter need its own call plan?

Cold weather brings boiler breakdowns, frozen condensate pipes and burst pipes, and they tend to come together. The Met Office issues weather warnings up to seven days ahead for snow and ice, among other weather types (Met Office). That gives you a little notice, but not much.

The problem isn't only volume. It's that the busiest days are the days you're least able to pick up. Plumbers on UK Plumbers Forums describe it well. One posted this in December 2013, two days before Christmas: "sat down at five with a beer and paper and the phones gone off 3 times, leaking gas pipe … plus 2 my boiler stopped working" (UK Plumbers Forums). In the 2018 freeze, another went to a house with "no physical water coming out the cold taps. Clearly frozen somewhere" (UK Plumbers Forums). You're on a job, hands full, and the next caller rings someone else. A plan means fewer decisions in the moment and a clear answer for every type of caller.

What do you need before the first cold snap?

• A short list of what you treat as an emergency, and what can wait.
• Your call-out charge and hourly or fixed prices, written down so you quote the same way each time.
• A voicemail greeting that says what to do in an emergency. See voicemail greetings for tradesmen.
• A way to reply to callers you can't answer, whether that's texts you send yourself or an automatic text back.
• Your phone settings checked, so unknown numbers ring through.

How do you set up a winter call plan, step by step?

1. Write your emergency triage list. A common starting point is no heating or hot water for a vulnerable customer, an active leak, and a suspected gas leak at the top of the list. A slow drip or a noisy radiator can wait. Writing it down means you answer the same way whether you're calm or flat out.
2. Prepare the gas safety line. If a caller says they can smell gas, the advice isn't yours to give on a callback. Tell them to call the national gas emergency number: 0800 111 999 in England, Scotland and Wales, or 0800 002 001 in Northern Ireland (GOV.UK). Put it in your greeting and your texts.
3. Prepare safe holding advice. For frozen pipes, the Met Office says to turn off the inside stop tap, open taps to drain the system, and thaw slowly with hot water bottles or towels soaked in hot water, never a naked flame (Met Office). For a frozen condensate pipe, Worcester Bosch tells householders to pour warm, not boiling, water along the pipe if it's safe to reach, then reset the boiler (Worcester Bosch). Write these as two short texts.
4. Set your prices and time windows before the rush. Decide your emergency call-out charge, evening and weekend rates, and what a first visit includes. Tell callers before you book them in, so nobody is surprised by the invoice. Give an arrival window rather than a time. One gas engineer on UK Plumbers Forums wrote: "I always give rough times now, say between 2and4" (UK Plumbers Forums).
5. Check your phone isn't hiding new customers. On iPhone, go to Settings > Apps > Phone > Screen Unknown Callers. If it's set to Silence, calls from unsaved numbers go straight to voicemail (Apple Support). See why calls go straight to voicemail.
6. Divert the calls you can't answer. Use a no-reply divert so unanswered calls go to voicemail or a text-back service after a set number of seconds. The codes are in call divert codes for UK networks, and your network's voicemail number is in UK voicemail numbers by network.
7. Load your reply texts. Keep a short set: emergency advice, "I'm on a job, back to you by" a time, and a fully booked reply with a realistic date. Our missed call text templates give you wording to start from.
8. Test it. Ring your own number from another phone and let it ring out. Check what the caller hears and what text arrives.

What should you say to callers you can't take on?

Be honest and quick. If you're full for three days, say so and give a date. People with no heating would rather know now than wait for a callback that doesn't come. If you work with another local engineer who has capacity, passing the job on keeps goodwill.

For emergencies, your reply should do three things: say you've got their message, give the safety step (stop tap, gas emergency number, warm water on a condensate pipe), and say when you'll call back. If you mainly do boilers and heating, our page for heating engineers shows how TradiesMate handles the calls you can't take.

What goes wrong with winter call plans?

• The greeting is out of date. A summer greeting with no emergency advice wastes the one moment a stressed caller is listening. Record the winter version in November.
• Silence Unknown Callers is still on. It's handy for spam, but almost every new customer is an unknown number.
• The divert is set too short. If the phone rings once and goes to voicemail, you can't answer even when you could have. Most no-reply diverts let you choose the ring time.
• No record of who called. On a busy day the missed calls list fills up quickly. Work through it at each break. Our guide to missed calls on the tools has a simple routine.
• Prices made up on the spot. It's easy to undercharge at 9pm in the snow. Decide your rates now.

How much time does this take?

For most sole traders it's an hour or so of admin, done once: writing your triage list and prices, recording a winter greeting, checking phone settings and setting a divert, then writing and testing your texts. If you run a second business number, see a second phone number for your business before you set the divert, because the codes apply to the number the SIM belongs to.

Key takeaways

• Write your emergency triage list and prices before the first cold snap.
• Put the gas emergency number (0800 111 999, or 0800 002 001 in Northern Ireland) in your greeting and texts.
• Give safe holding advice for frozen pipes and condensate pipes by text, based on official guidance.
• Turn off Silence Unknown Callers and set a sensible no-reply divert.
• Test your set-up by ringing yourself from another phone.
