A blocked toilet is usually a small plumbing job, but if it’s overflowing or you only have one toilet in the house, it can quickly become urgent.

In most cases, the cost to unblock a toilet is around £75 to £200, depending on the type of blockage, but costs can increase further if rodding, jetting or an emergency call-out are needed.

How Much To Unblock a Toilet?

These days, plumbers typically charge between £75 and £200 to unblock a toilet. Of course, this depends on what’s triggered the problem and how challenging it is to unclog.

Your local plumber can usually sort a simple pan blockage with a plunger or snake. Typically, you’ll pay around £75–£100 and it takes less than an hour. Are the pipes outside your toilet blocked? Then this is pricier at about £100–£150 for rodding. It’ll cost a little more if jetting is needed – roughly £150–£200.

Emergency call-outs or London jobs will usually cost more. Plumbers charge a call-out fee, not to mention a steeper first-hour rate. Does your toilet keep blocking? You might need a CCTV drain survey to find the root cause, which costs £90–£500 on average.

How Much Does It Cost to Unblock a Toilet?

Below is a table highlighting the costs that you can expect when it comes to unclogging a toilet:

Prices are typical weekday rates. London and urgent call-outs tend to cost more.

Cost of Unblocking Toilets Across the UK

Here are some real examples of the cost to unblock toilets in different locations in the UK.

Emergency Toilet Unblocking Costs

Emergency toilet unblocking usually costs more than a standard weekday visit.

If you need an emergency plumber in the evening, at the weekend, or at short notice, expect to pay a higher call-out fee and a higher first-hour rate. In many cases, an emergency blocked toilet call-out costs around £100 to £200, with more severe jobs costing more if specialist drain equipment is needed.

For urgent jobs, many plumbers can attend the same day, although emergency and out-of-hours visits will cost more.

If you can't wait, you can get quotes from emergency plumbers near you.

A blocked toilet is more likely to count as an emergency if:

• It is overflowing
• You only have one toilet in the property
• Sewage is backing up into the bowl or nearby drains
• The blockage is affecting other fixtures such as sinks or baths

If the blockage is not urgent and the toilet is still draining slowly, booking a standard weekday appointment is usually the cheapest option.

Labour Costs and Timescales

Your labour cost depends on which trades you need and how long they’re on site. Most plumbers charge a call-out or first hour fee of about £75–£100, then around £30–£40 per half hour after that. For a full day’s work, expect £300–£400.

Minor toilet blockages can usually be cleared in under an hour. More stubborn issues, especially if the pipework is affected, can take up to two hours and cost closer to £200.

What you pay for labour comes down to the method the plumber needs, and that depends on where the blockage is and how stubborn it turns out to be.

• A plunger or toilet snake clears a simple blockage in the pan in under an hour, so it sits at the lower end for labour.
• Drain rodding reaches a blockage in the external pipework, which takes longer and adds to the cost.
• High-pressure jetting can take 1 to 2 hours to shift a stubborn or repeat blockage.
• Removing the toilet to reach the blockage is the most involved job and costs the most.

What Else Adds to the Cost of Unblocking a Toilet?

These extras sometimes crop up with a blocked toilet job:

New Pipework

If the current pipework that connects to your toilet is insufficient or faulty, then it may need to be replaced. It could be that it is damaged or corroded and you can't see it. If this is the case, you can expect to pay around £30-£40 for new pipework to be installed.

If a pan connector or short section of pipe needs replacing, parts are typically £30–£40 plus labour.

Replacement Toilet

If your toilet is prone to blockages or quite old, then it may be a good idea to think about replacing your old toilet with a new one now. The average cost to have a new toilet installed is around £300-£600.

Drain Unblocking

If you start to notice foul odours coming from your drains or your sink, then you may have a blockage in your drains. A professional drain unblocking service will usually cost around £80-£150 depending on the issue and the method used to unblock it.

Factors That Impact the Cost of Unblocking a Toilet

There are several factors that may affect the cost of unblocking a toilet. Below is a list of the main things that could have an impact on the overall cost of the job:

• Type of Blockage — A severe blockage, such as a blocked toilet drain or a blockage within the pipework, could take much longer than a simple blockage, and you should expect to pay for the work.
• Ease of Access — The location of the blockage can affect the overall cost of the job. A blockage in the toilet bowl U-bend is much easier to access than one further down the waste pipe. The more difficult it is to reach the blockage, the more it will cost.
• Location of Property — Your location within the UK can affect how much you pay to have your toilet unblocked. Plumbers in the London area can charge around £30 to £100 more per day than plumbers based in other parts of the UK.
• Condition of Pipework — Older or corroded systems can complicate the job and push up the cost of unblocking. The severity of any damage or build-up inside will affect how long the work takes and what you end up paying.

What's Involved in Unblocking a Toilet?

Here's what a plumber will normally do to unblock your toilet, from start to finish.

Before the Job

• Finding the Blockage — The plumber checks where the blockage is and what has caused it, to determine the best approach for unblocking.
• Protecting the Area — They protect the area around the toilet and get their tools ready. Ensure you have a clear price breakdown before any work begins.

During the Job

• Simple Unblocking — They start with a plunger or toilet snake to clear a simple blockage in the pan.
• Advanced Unblocking — If the blockage sits further down, they may rod or jet the external drain to shift it.
• Testing — They flush the toilet to check the water is flowing freely again.

After the Job

• Tidying Up — The plumber clears away any waste and leaves the area tidy.
• Preventive Measures — They may suggest ways to avoid future blockages, such as what not to flush. You should test the toilet yourself before they leave.

Can I Unblock a Toilet Myself?

Yes, for minor blockages. Whether you need a plumber depends on the type and severity of the blockage. Firstly, try a plunger. Then, give a toilet snake a go. Is the blockage within the pipe itself, or does it keep coming back? If so, book a plumber to avoid damaging the system.

Blockages in the external pipework and drainage systems can be quite difficult to reach and will require specialist equipment to complete the unblocking.

If you want to try a small DIY unblock first, you may need the items below.

It's best not to use strong chemical drain cleaners yourself, as they can harm your pipes and fittings and are dangerous to handle.

So, how much does it cost to unblock a toilet yourself? The tools are the only real cost, and even buying both a plunger and a toilet snake is a one-off spend of under £80. A plumber charges from around £75 for a simple blockage, so trying it yourself first can save money. If a plunger or snake won't shift it, though, a plumber is worth the cost to avoid damaging the system.

Checklist: Hiring a Professional to Unblock a Toilet

Before you hire a professional to unblock a toilet, keep these points in mind:

• Are they WaterSafe approved? WaterSafe is a government-backed scheme for approved plumbers. Members are vetted for competency and must comply with UK water regulations.
• Are they a member of a recognised trade body? Membership of the Chartered Institute of Plumbing and Heating Engineering (CIPHE) or the Association of Plumbing and Heating Contractors (APHC) shows they meet recognised professional standards.
• Do they have insurance? Public liability insurance protects you if something goes wrong.
• Will they provide an itemised quote? Ask for a clear breakdown of the unblock toilet costs, including call-out fees and what happens if the blocked toilet turns out to be more complex to unclog than expected.
• Will they use the right method to unblock the toilet? Some blockages need more than a plunger. Ask whether rodding or jetting is included if needed, and whether they carry the specialist tools for both.
• Will they clean up afterwards? Confirm that any waste or debris removed during the job will be disposed of properly and that the area will be left tidy.
• Do they have positive reviews? Check their MyJobQuote profile to read the feedback they have received from previous customers.
