Unblocking a Toilet – What’s Involved?

The moment you realise your toilet is clogged can be a stressful experience, particularly if it's the only one in your home. Blocked toilets need urgent attention, and knowing the costs associated with getting them cleared can help you make an informed decision. Here's a closer look at how much it costs to unblock a toilet.

To give you a general idea, most blocked toilet clearance services will charge between £30 and £60 on average.

Average Cost of Unblocking a Toilet

The cost to unblock a toilet depends on the complexity of the blockage. In most cases, it should take around 30 minutes, and the price will typically range from £30 to £60.

For more involved blockages, such as those requiring specialised equipment or more extensive work, the cost can go up. Severe blockages may cost as much as £100 to £200, depending on the circumstances.

Call-Out Charges:

Plumbers usually charge a call-out fee to assess the blockage. Assuming the issue is minor and the blockage is easily accessible, the plumber will aim to clear it within 30 minutes. This is the most common scenario for a cost of around £45.

Cost Breakdown for Different Types of Jobs

A basic blockage within the toilet itself can typically be cleared with a plunger or toilet snake. Both methods are usually completed within 30 minutes, costing between £30 and £60.

If the blockage extends to the pipework or the external drains, costs will rise, and more time will be required to fix the problem.

DIY Blockage Solutions

If you believe the blockage is minor and confined to the toilet itself, you might consider attempting a DIY solution. Here’s an outline of common tools and their costs:

Though these materials may seem inexpensive, they’re usually suited for relatively simple blockages. Anything more serious may require professional intervention.

Additional Costs to Consider

In some cases, additional work might be needed to prevent recurring blockages or resolve underlying issues. Here are some possible extra costs to consider:

• New Pipework: If the pipes connected to your toilet are damaged or corroded, they may need to be replaced. This could cost between £30 and £40 for the new pipework.
• Replacing the Toilet: An old or frequently blocked toilet may need replacing. Installing a new toilet will typically cost around £300 to £600.
• New Bathroom Installation: If you decide to overhaul your bathroom, including replacing the toilet and other components, expect to pay anywhere from £5000 to £10,000, depending on the materials used and the size of the space.
• Drain Unblocking: Should the problem extend to your drainage system, a professional drain unblocking service will cost around £80 to £150, depending on the nature of the issue.

Labour Costs and Timeframes

When hiring a plumber, the standard daily rate typically falls between £150 and £200. Minor unblocking jobs can often be completed in around 30 minutes for £60, while more complex issues could take up to two hours, with costs rising to £200 or more.

Cost Factors When Unblocking a Toilet

Several variables affect the final price of unblocking a toilet, including:

• Type of Blockage: The severity of the blockage will play a significant role in the cost. Minor blockages can usually be resolved quickly, while more complex ones, like those in the pipes or drains, take longer and can be more costly.
• Ease of Access: If the blockage is in an easily accessible location, it will take less time to resolve. However, if it's in the pipework or the drainage system, it may be harder to reach, which will increase both the time and the cost.
• Location: Plumbers in major cities like London generally charge higher rates compared to those based in smaller towns or rural areas. In London, expect to pay £30 to £100 more for the same job.

Methods of Unblocking a Toilet

To unblock a toilet, there are a few methods commonly used, depending on the nature of the blockage:

1. Unblocking with a Plunger

This is the most common method for minor blockages. The steps are as follows:

1. Place the plunger in the toilet bowl, ensuring it covers the drain outlet and forms a seal.
2. If the water level is low, you may need to add more water.
3. Use a firm, slow push to create pressure, followed by a quick pull to create suction. Repeat this process 15–20 times, checking if the blockage clears.

2. Unblocking with a Toilet Snake

If a plunger isn’t sufficient, a toilet snake can help. The snake is a flexible tool with a coiled end that can break up blockages further down the pipes. Here's how to use it:

1. Feed the snake into the toilet and direct it down the U-bend until it contacts the blockage.
2. Twist the handle to break up or dislodge the blockage.
3. Repeat the process until the toilet clears.

3. Chemical Unblocking Agents

Chemical agents can help dissolve blockages caused by organic waste. They should be used carefully:

1. Always read the product instructions to ensure safe use.
2. Pour the agent into the toilet bowl and allow it to sit for the recommended duration.
3. After waiting, flush the toilet to see if the blockage has cleared.

Can I Unblock a Toilet Myself?

Yes, in many cases, you can unblock your toilet yourself using a plunger, toilet snake, or chemical agents. These methods work well for minor blockages. However, if the blockage is further down the pipework or in the drains, you may need to hire a plumber, as this requires professional equipment and expertise.

Building Regulations and Planning Permission

You do not need planning permission or to worry about building regulations when unblocking a toilet. These types of tasks are considered maintenance work, and no permits are required.

Checklist for Hiring Contractors

Before hiring a plumber to unblock your toilet, ensure they meet the following criteria:

• Guarantees: Does the plumber offer any warranties on the work?
• Breakdown of Costs: Ensure you get an itemised quote for the job to avoid hidden fees.
• Experience: Does the plumber have specific experience with the type of blockage you have?
• Reputation: Look for reviews or testimonials to assess their reliability.
• Method: Confirm which method will be used for unblocking, and whether any specialised tools or materials are required.
