'Free Call-Out' Plumbers: What It Really Means

Where the cost of the journey goes instead

Getting a plumber to a London address at night is expensive for the business before a spanner is turned: van running costs, congestion and parking charges, and an engineer paid to drive rather than repair. Every firm recovers that somewhere. A charge you can see in advance is not better or worse in itself than one built into the rest of the bill. The problem is when it is hidden until you are standing in a flooded kitchen and cannot say no.

These are the usual places a free call-out is paid for. None of them is dishonest on its own. Each one only becomes a problem if you are not told about it before the visit.

• A minimum charge: the first hour, or the first 30 minutes, is billed in full however quickly the job is done
• A diagnosis or inspection fee: coming out is free, but finding the fault is charged, and it is only waived if you go ahead with the repair
• A higher labour rate: the hourly rate is set to cover travel, sometimes with a separate night or weekend multiplier
• Parts mark-up: a washer that costs pennies or a £15 valve is billed at several times what it costs at a plumbers’ merchant
• A booking or admin fee taken by card when you confirm the visit, often by a call centre rather than the engineer

Questions that expose the real price before anyone comes

Ask these on the phone and write down the answers, along with the time of the call and the name of the person you spoke to. A firm that is confident in its pricing will answer them without fuss.

• If the engineer arrives, looks and I decide not to go ahead, what do I pay?
• Is there a minimum charge, and how long does it cover?
• What is the labour rate at this time of night, and is it charged by the hour, the half hour or in 15-minute blocks?
• Are parts charged at cost or with a mark-up, and will I be told the price of a part before it is fitted?
• Are your prices including VAT?
• Will the engineer give me a price for the repair before starting, or does the clock run from arrival?

If the answer to the first question is anything other than a clear figure or "nothing", treat the free call-out as a sales line rather than a price.

What the law says about the bill you end up with

Under the Consumer Rights Act 2015, what a trader tells you about the price and the service, spoken or written, can become part of the contract if you relied on it when deciding to book (section 50). If you were told the call-out was free and then billed for attending, that statement is on your side. Where no price was agreed at all, section 51 says you must pay a reasonable price for the service, and no more.

Since April 2025, consumer law under the Digital Markets, Competition and Consumers Act 2024 also treats leaving mandatory charges out of a headline price, known as drip pricing, as a misleading practice. The Competition and Markets Authority’s price transparency guidance covers it. A compulsory attendance or diagnosis charge that only appears after you have booked is exactly what that guidance targets.

One thing that surprises people: the usual 14-day right to cancel a contract made at home does not apply when you asked a trader to visit for urgent repairs (regulation 28 of the Consumer Contracts Regulations 2013). It does still apply to extra work or goods beyond the urgent repair, such as a new boiler or a bathroom refit sold to you on the same visit. That is another reason to agree the price before work starts rather than argue about it afterwards. Our guide to how plumbers quote a job covers what that agreement should include.

Is a free call-out ever the better deal?

Sometimes. For a planned job during the day, a firm that does not charge to visit and quote is common and perfectly fair: the quote is the product, and they win enough work from quoting to cover the trips that lead nowhere. For a leaking tap or a replacement toilet, getting two or three free quotes in daylight is sensible.

An emergency at 2am is different. You are not comparing quotes, you need one person to turn up and stop the water. In that situation a visible, fixed attendance charge plus a repair price agreed on site is usually easier to judge than a free call-out with an open-ended hourly rate, because you know the worst case before the van sets off.

The £60 call-out we charge at any hour is set out on the pricing page, and the repair price is agreed with you on site before any work starts. If you decide not to go ahead, you know what the visit has cost. For how attendance charges are usually structured across the market, see plumber call-out charges explained.

Warning signs on the doorstep

Most plumbers who advertise a free call-out are honest about how they recover it. A few use it to get through the door and then set the price once you are committed. These are the signs to stop and ask before any work starts.

• The engineer starts dismantling before telling you what is wrong or what it will cost
• The price is given as an hourly rate with no estimate of how many hours
• A small repair turns into "the whole valve, pipe run or boiler needs replacing tonight"
• You are asked to pay in cash, or to a personal account, with no written invoice
• The company name on the invoice is not the one you called, or has no address

You can ask an engineer to stop at any point and give you a price for what is left. If you are unhappy, pay what was agreed, write "paid under protest" on the invoice and take it up in writing afterwards. More on this in emergency plumber scams and how to spot them.
