Picture a tap that has dripped for a month. You have phoned four plumbers. Two did not ring back, one said they would come next week and did not, and the fourth quoted a call-out charge that made you put the phone down and buy a bucket. Nothing is broken enough to be urgent and nothing is big enough to be interesting, and that is precisely why it is still dripping.

Why small jobs get turned down

Look at it from the van. A plumber who accepts a tap washer job across town spends half an hour driving there, twenty minutes on the job, half an hour driving back, and has to price it against a full day's work they could have done instead. Charge the honest figure and the customer thinks it is robbery for twenty minutes of work; charge less and the plumber has lost money on the morning. Most solve this with a minimum charge, often expressed as a first hour at a fixed rate, and many quietly do not answer small-job enquiries at all when they are busy.

The minimum charge is not a scam. It covers the travel and the fact that the plumber cannot sell that hour twice. But it does mean the way to get a small job done at a fair price is to make it worth someone's trip.

Make one visit out of five jobs

Walk round the house with a notepad. The tap. The toilet that runs on after flushing. The radiator in the back bedroom that never gets hot at the top. The outside tap you meant to have fitted two summers ago. The shower hose that has perished. The bath waste that drains slowly. Individually, none of these gets a plumber out. Together, they are a morning's work at a day rate, which is the kind of booking that gets a call returned.

Present it that way when you ring. 'I have a list of five or six small jobs, probably a half day, can you come out and do the lot?' That sentence changes the conversation. The plumber can quote a half-day rate, plan the parts, and arrive with a bag that covers all of it. You pay for the hours used, not for five separate call-outs.

Parts, and who buys them

Small jobs are often held up by a part rather than by labour. A tap with a ceramic cartridge needs the right cartridge for that tap, and there are dozens. A toilet flush valve is likewise specific to the cistern. If you can find the make and model in advance, photograph it and send it, the plumber can bring the part or tell you where to buy it before the visit. Most will fit parts you supply for straightforward items, though they will not guarantee a part they did not choose, which is fair.

Ask whether the quote includes parts and whether there is a mark-up. Some plumbers charge trade price plus a percentage, some pass it through at cost and put the margin on labour. Either is reasonable; a surprise on the invoice is not.

Before you accept the drip forever

A dripping tap wastes a surprising amount of water on a meter and wears the seat of the tap, so a job that would have been a washer becomes a new tap. A toilet that runs on can do the same to your water bill. These are cheap when done early and they get less cheap the longer they wait.

Of the 3,554 plumbers listed on this site, a good many are one-person firms who take small domestic work and say so in their listing. Look through the plumbers near you for the ones who mention general repairs, or write the whole list into a single request and ask for quotes on the batch. Then put the bucket back under the sink where it belongs.
