The answer depends on several factors, including the type of toilet, the complexity of the job, and who you hire. In this guide, we’ll break down average toilet installation costs, what affects the price, and tips to help you budget effectively.
Average Toilet Installation Cost in the UK (2025)
On average, the cost to replace a toilet in the UK ranges from £150 to £500. This usually includes removing your old toilet and fitting the new one.

What’s Included in the Toilet Installation Cost?
A standard toilet installation typically covers:
- Removal of the old toilet – safely disconnecting and disposing of your existing toilet.
- Fitting the new toilet – connecting it to your water supply and waste outlet.
- Basic sealing and finishing – applying sealant around the base and ensuring it’s watertight.
Additional work, such as fixing flooring or upgrading pipework, will add to the overall bill.
Factors That Affect Toilet Installation Costs
Not every job is the same, and the following factors will influence how much you’ll pay:
- Type of Toilet
- Close-coupled toilets are generally the cheapest and easiest to install.
- Back-to-wall toilets or wall-hung toilets require concealed cisterns and more complex installation, making them more expensive.
- Smart toilets with bidet functions, heated seats, or automatic flushing are at the premium end.
- Labour Rates
Plumber rates vary across the UK.
- In London and the South East, expect higher labour charges (around £60 – £100 per hour).
- In other regions, rates may be closer to £40 – £60 per hour.
- Plumbing Adjustments
If your new toilet doesn’t align with the existing pipework, your plumber may need to adjust connections, which adds time and cost.
- Disposal Fees
Some plumbers include disposal of the old toilet in their quote, while others may charge an additional £20 – £50.
- Extra Repairs
Leaking pipes, damaged flooring, or outdated cistern systems may require repairs before the new toilet can be fitted.
How Long Does Toilet Installation Take?
For a straightforward replacement, most plumbers can complete the job in 2–4 hours. More complex installations, such as wall-hung toilets with concealed cisterns, could take a full day or more.
