How Much Does a Plumber Charge to Replace a Toilet

At Lillian Purge, we specialise in SEO for Plumbers. Here’s what to expect when getting a plumber to replace a toilet.

Replacing a toilet is one of the most common plumbing jobs in the UK, and costs can vary depending on location, materials, and the complexity of the installation. On average, most plumbers charge between £120 and £250 for a straightforward toilet replacement, though this can rise if additional work is needed.

Let’s break down what affects the total price and what customers can expect from a professional installation.

Typical Cost Breakdown

A basic toilet replacement usually involves removing the old unit, checking pipework, fitting the new toilet, and testing for leaks. The cost includes both labour and materials, though the toilet itself is often supplied by the homeowner.

• Labour costs: Most plumbers charge hourly rates between £40 and £80, depending on region and experience. A simple swap usually takes one to two hours.

• Call-out fees: Some plumbers charge a minimum call-out fee, particularly for smaller jobs. This might be between £50 and £80.

• Toilet unit: If the plumber supplies the new toilet, the price can range from £100 for a standard model to £400 or more for premium designs.

• Disposal fees: Removing and disposing of the old toilet may add £20 to £40.

Altogether, the total cost of replacing a toilet typically falls between £150 and £400, depending on your location and the specific requirements of the job.

Factors That Affect the Price

Not all toilet replacements are straightforward. Several factors can push the price higher or lower:

1. Type of toilet
Close-coupled toilets are the easiest to fit, while wall-hung or concealed-cistern models require more time and precision. Complex designs can add £100 or more to the labour cost.

2. Condition of existing plumbing
If the soil pipe, shut-off valve, or water supply line needs repair, the job will take longer and cost more. Older properties with outdated pipework often need extra attention to avoid leaks or compliance issues.

3. Access and location
Replacing a toilet in a small cloakroom or a tight space can be more time-consuming. Multi-storey properties may also involve additional pipework checks.

4. Region
Labour rates vary across the UK. Plumbers in London or the South East typically charge more than those in smaller towns or rural areas.

5. Additional work
If the job involves upgrading flooring, replacing tiles, or adjusting a vanity unit, these extras can significantly increase total cost.

How Long Does It Take to Replace a Toilet

For a simple like-for-like replacement, the work can usually be completed within two hours. However, if the old toilet has rusted bolts, damaged fittings, or needs new pipe connections, the job could take up to half a day.

Some plumbers also include post-installation testing, sealant work, and cleanup in their quote, ensuring the new unit is fully operational and leak-free.

Do Plumbers Charge by the Hour or by the Job

Most plumbers prefer fixed-price quotes for smaller jobs like toilet replacement, as it provides clarity for both parties. However, some still charge by the hour if they anticipate complications or need to inspect the setup first.

Fixed quotes often include travel, labour, and minor materials, while hourly jobs may add these separately. Always confirm before booking to avoid misunderstandings.

Signs You Might Need a Toilet Replacement

Sometimes, repair isn’t enough. You may need a full replacement if:

• The toilet leaks frequently or wobbles when in use.

• The flush mechanism fails regularly despite repairs.

• There are cracks in the ceramic base or tank.

• The model is outdated or inefficient with water usage.

Upgrading to a modern, water-efficient toilet can reduce water bills and prevent recurring problems.

How to Get the Best Value

To get fair and accurate pricing, it’s worth getting two or three quotes from local plumbers. When comparing estimates, check that each includes the same details such as disposal, fitting, and parts.

Ask for confirmation on:

• Whether the plumber provides the toilet or you supply it.

• If the quote includes VAT.

• Whether removal of the old unit is covered.

• Any additional work that might increase the price.

Cheap quotes aren’t always the best option. A professional plumber who uses quality fittings and guarantees their work can save you time and money in the long run.

Additional Costs to Consider

Sometimes a toilet replacement is part of a larger bathroom update. In these cases, plumbers might need to coordinate with tilers, electricians, or builders. Costs can increase to £600 or more when multiple trades are involved.

If your toilet replacement includes new flooring or retiling, confirm in advance whether the plumber will handle these elements or if you’ll need separate contractors.

When DIY Isn’t Worth the Risk

While replacing a toilet might look simple, it’s easy to run into problems such as incorrect sealing, poor alignment, or small leaks that cause long-term damage. A professional plumber ensures that the installation meets safety and water regulations, preventing costly issues later.

Professional fitting also gives you peace of mind knowing your new toilet will perform reliably from day one.

Final Thoughts

The cost of replacing a toilet in the UK typically ranges from £150 to £400, depending on materials, labour rates, and job complexity. For most homeowners, hiring a qualified plumber offers the best balance of safety, reliability, and long-term value.

By getting a clear, itemised quote and choosing a trusted local professional, you can ensure your toilet replacement is completed efficiently and to a high standard.
