What Happens If It Takes Longer Than 1 Hour?

We Pride Ourselves on Efficiency. in 99% of Cases, Your Bill Will Be Exactly £120.

However, in the rare 1% of scenarios where a blockage is exceptionally stubborn or complex, we have a fair pricing structure in place. Unlike competitors who charge you for a full second hour even if they only work 10 minutes, we charge in smaller intervals.

1. Standard Blockage Overtime (Discounted Rate) If the blockage just needs a little extra time with standard tools, we apply a discounted rate after the first hour.

• Cost: £22.50 per 15 minutes.

• Benefit: You only pay for the exact time used.

2. Heavy Duty Machinery Overtime If the blockage requires advanced high-pressure water jetting or mechanical machinery after the first hour, we apply our machinery rate.

• Cost: £60 per 30 minutes.

• Benefit: You are only paying for the heavy equipment if it is absolutely necessary to clear the drain.

Factors That Usually Influence Cost

While we strive to keep everything within the £120 first-hour rate, here is how we handle different variables:

1. Severity of the Blockage Most sink, toilet, and manhole blockages are cleared quickly using rods or standard mechanical tools. This falls comfortably within our £120 fixed hour.

2. Location (London & South East) We serve London, Hertfordshire, and Middlesex. We do not add “London congestion” surcharges to our advertised rates.

3. Emergency vs. Scheduled Whether it’s a blocked toilet or an overflowing external drain, our goal is the same: fix it fast, usually within 60 minutes.

Typical Industry Costs vs. Our Costs

For context, here is what you might see if you shop around for quotes on directories like Checkatrade, compared to our direct booking price:

• Internal Blockages (Sinks/Toilets):

  • Competitor Average: £90 – £150 + VAT (often with a call-out fee)

  • Our Price: £120 Fixed (First Hour)

• Complex External Drains:

  • Competitor Average: £180 – £300+

  • Our Price: £120 (for 99% of jobs). Complex jobs billed transparently in increments.

Why Choose Professional Unblocking Over DIY?

While a plunger is fine for a slow-draining sink, chemical cleaners can damage your pipework and rarely solve the root issue.

1. Safety: We remove bio-hazards and sewage safely.
2. Efficiency: Our vans are equipped to get the job done in under an hour in the vast majority of cases.
3. No Risk: You don’t pay for equipment rental or risk damaging your own ceramics.
