Why plumbers lose winter boiler jobs to missed calls

Plumbers lose winter boiler jobs to missed calls because a household with no heating cannot afford to wait for a call back. The first plumber who answers, and can give them a time, is the one who gets the job. Winter squeezes those calls into cold snaps and dark evenings, which are the hours you are least able to pick up.

None of that is a reason to answer every call with a spanner in your hand. It is a reason to decide, before the weather turns, what happens to the calls you cannot take.

Why does a missed call cost more in winter?

Because the caller's situation changes what they do next. In June, somebody with a dripping tap can leave a voicemail and think nothing of hearing back tomorrow. In January, somebody with a cold house, a child in the bath waiting for hot water, or an elderly parent sitting in a coat, is not choosing a plumber on reputation. They are choosing one who is available tonight.

So the maths of a missed call changes. A summer enquiry that rings out can still be yours if you return it within the day. A winter breakdown that rings out may well have been picked up by somebody else before you are back in the van, and your call back reaches a customer who has already said yes to a time from another firm.

What goes with it is not only the one job. A household that finds a plumber it trusts on a bad night has a name to ring the next time something goes wrong, and a name to give the neighbour who asks who they used.

When do winter boiler calls actually come in?

Not evenly, and not at times that suit a working day.

After dark. In the UK the clocks go back one hour at 2am on the last Sunday in October, which in 2026 is 25 October. From then on, a household that is out at work all day can come home to a dark, cold house, and the first sign that something is wrong can be the moment the heating is supposed to come on in the evening. That call arrives when you are finishing a job, driving home or sitting down to eat.

On the first hard frost. A run of freezing nights brings a particular kind of call, covered below, and it can bring several at once, because the cold arrives for every house in the area on the same morning.

At weekends. A heating fault does not keep office hours, and a family facing a cold Saturday and Sunday has every reason to keep ringing round until somebody picks up.

Which winter boiler jobs are really yours?

Not all of them, and it matters which ones you can take.

Work on a gas boiler is gas work, and under the Gas Safety (Installation and Use) Regulations 1998, gas work in homes has to be carried out by an engineer on the Gas Safe Register. If you are a plumber who is not registered, a genuine gas fault is not your job, however urgent the caller sounds. If you are registered, it is urgent work that the caller needs doing that day.

Either way, some winter calls about a boiler are not gas work at all:

• A frozen condensate pipe. Condensing boilers drain water away through a plastic pipe, and where that pipe runs outside it is exposed to frost. When it freezes, the boiler stops. Worcester Bosch, for one, tells its customers that the signs can include a gurgling noise from the boiler and, on boilers with a display, an EA fault code.
• Low pressure. A boiler that has lost pressure may need a leak found on the heating system rather than any work on the boiler itself.
• Frozen or burst pipework. Exposed pipes in lofts, garages and outside walls are plumbing work in anyone's book.
• Radiators. Cold spots, noisy systems and radiators that will not heat up.

The difference between a call you can take and one you cannot can come down to two or three questions asked at the start. Is there any smell of gas? Is anything showing on the boiler's display? Has the weather been freezing overnight? Asked every time, they tell you which calls to ring back first, and which to pass on quickly so the caller can find somebody who can help.

What happens to the calls you do not answer?

Three things, and only one of them is good for you.

Some callers leave a voicemail and wait. They are the ones you can still win, and every hour you take to ring back makes it less likely.

Some callers hang up and ring the next plumber on the list. You see a missed call from a number you do not recognise, ring it back at eight in the evening, and find they already have somebody coming at nine the next morning.

And some callers never show up on your phone at all, because they rang while you were on another call, heard an engaged tone, and moved straight on. Those are the ones nobody counts.

Who should you ring back first?

When you come off a job to a list of missed calls, the order you work through them decides which jobs you keep. Ringing back in the order the calls arrived feels fair, but it is not the order that matters on a cold night.

• Anyone who mentioned a smell of gas. First to make sure they have rung the emergency number, whether or not the work afterwards turns out to be yours.
• Houses with somebody vulnerable in them. A baby, an elderly relative, anyone unwell. Those are the calls where a delay costs more than a job.
• No heating and no hot water. A household with neither has the most reason to keep ringing round.
• Anything that sounds like frozen pipework or a frozen condensate pipe. Some can be sorted with a few minutes of advice on the phone.
• Everything else. Quotes, dripping taps and planned work can wait until the morning, and the callers expect them to.

Whatever order you choose, give every caller a realistic time. A plumber who says tomorrow at ten and turns up at ten keeps the customer. One who says first thing and arrives at two has made the same mistake as the one who never rang back.

What can you put in place before the cold arrives?

Some of this costs nothing. All of it is easier to do in October than in the middle of a cold week.

• Decide what winter work you take. Gas or not, how far you will travel in bad weather, whether you take calls from outside your usual area. Put the answer on your website, so the wrong calls are fewer to begin with.
• Keep room in the diary. A diary filled with planned work leaves no space for the urgent breakdown. Holding back a slot or two a day in the coldest weeks gives the phone somewhere to put the urgent job.
• Write down your first questions. The three above, plus the address, whether the caller owns the property, and whether anybody vulnerable is in the house. Asking the same questions every time makes the call back quicker and the order you ring people back fairer.
• Change your voicemail greeting for winter. Say when you will ring back, and what the caller should do if there is a smell of gas.
• Divert the phone when you cannot pick up. A divert to a person, whether that is somebody in your family, an office or an answering service, turns a ringing phone into a written message with the questions already asked.

Is paying for answering through winter worth it?

Only you can put the numbers in, but the working is simple, and it is worth keeping cautious. Take the calls you think you miss in a typical winter week. Multiply by the number of winter weeks you care about. Then assume only one in five of those calls would ever have turned into a job, which is the deliberately low rate the calculator on our homepage uses.

As an example of the working: three missed calls a week over three months of winter, thirteen weeks, is 39 calls. One in five of 39 is just under eight jobs. Put your own average breakdown job next to that number, and you have a rough idea of what went to somebody else last winter.

Against that, a plan that books breakdowns into your diary and adds out-of-hours options is Growth, at £249 a month, so £747 for those three months, plus a one-off setup fee from £49.50, normally £99. A plan that answers and sends every message on, without booking, is Essential at £129 a month, or £387 for the same period. Every plan and what it includes is set out under plans and pricing, and the calculator will run the sum again with your own figures.
