You’ve just flushed the toilet, and then disaster strikes: your toilet is clogged!
You’ve probably tried all the tips you could find online, but nothing seems to work, and now it’s time to call a plumber.
When you consider that a plumber could easily charge £100 just to unclog your toilet, it’s worth thinking twice before making the wrong decision!
Luckily, I’ve done some research into the rates charged by drain-clearing companies. I’ve compared them to the 3,000 toilet unblocking jobs done through Yoojo since 2022, so I can present you with a comparison of the two options.
Let's go!
Toilet unblocking: what plumbers charge in the UK?
The prices plumbers charge to unblock a toilet can really vary widely! That's because it mainly depends on the type of company you decide to hire.
Here’s a quick comparison between a traditional company and a service provider to give you an idea:

Why you should delegate the job to a plumber
It's a fair question to ask: Do I really need to call a plumber? Couldn't I just buy the right tool and do it myself?
Here are two reasons why it’s worth delegating this task:
✅ Your toilet is really blocked:
- When you flush, the water doesn’t go down at all
- This isn’t the first time it happened
- It’s happening more and more frequently
- You’ve already tried a plunger and drain cleaner without success
❌ Buying tools might not be worth it:
- The tools are too expensive (over £100 for a drain snake or pump)
- You’ll rarely use them
- They take up space
- You’re not sure if they’ll be effective
- The prices are comparable to a specialised unblocking service
I'm a tenant, do I need to pay the bill?
When a blockage occurs in the toilet pipes, unless it’s due to an exception like a breakage, design flaw, or incorrect connection, you’ll be responsible for the cost. Legally, it’s considered maintenance work, so the tenant always bears the cost of unblocking or cleaning the toilet.
Which plumber to hire: classic plumbing company vs. Yoojo
As you might expect, there’s a big price difference between a company and a plumber through a personal service, and there are several reasons for that. Let me share them with you.
The Plumber from a classic company:

These are the most expensive, as they have to cover social contributions, employer/employee charges, and maintain costly equipment.
The plumbers through Yoojo:

Cheaper and without the hefty bill, the plumber offering personal services (service provider) is a status designed to for small everyday help. It’s perfect for those looking to earn a bit of extra money.
How to make the right choice?
Figure out what you need to quickly make a decision.
Choose a classic plumbing company:
- If you're a professional
- If you need an invoice
- For large, complicated jobs (like a construction site)
Choose a plumber through Yoojo:
- If you're a private individual
- For straightforward jobs
- If you don't need an invoice
- If you want to save money
