Call for availability

For safely accessible faults that can be resolved on the first visit. Parts, materials and further work are quoted separately for your approval. If a first-visit fix isn’t possible, the agreed visit charge still covers the call-out and assessment. We explain the fault and quote any parts, further investigation or larger repair for your approval.

Plumber inspecting a toilet cistern with the lid removed

Tell us whether the bowl rises when flushed, whether wastewater is overflowing and if this is your only toilet. Mayfair arranges suitable blockage investigation and clearance; a running cistern or failed flush mechanism is a separate plumbing repair.

Your repair question, answered

My toilet is blocked. Who should I call?
Plumber inspecting a toilet cistern with the lid removed

Choose toilet unblocking if water rises in the bowl or will not clear. Mention whether other drains are affected and if this is your only toilet; avoid repeated flushing when the level rises. A toilet that drains normally but keeps refilling needs a different plumbing repair.

The work, explained

What the visit can include

  • Assess whether the restriction appears local or part of a wider drainage problem.
  • Use suitable clearance equipment for the accessible installation.
  • Check operation after clearance and flag evidence of further defects.

A clearance, camera survey, jetting visit and structural repair are different scopes. We explain the proposed method and price; excavation, lining, specialist equipment and reinstatement are not automatically included in a small-repair visit.

What to include in your enquiry

  • Avoid repeated flushing if the bowl is rising.
  • Mention any suspected item flushed and products already used.
  • Tell us whether nearby sinks, baths or neighbouring homes are affected.

A local obstruction, blocked soil pipe and external sewer fault need different work. Toilet removal, new seals, jetting and structural repairs are separately scoped where required.

Example work, explained

Investigating a drain that keeps blocking

The problem
A blockage returns after clearance, or several outlets drain slowly. Repeating the same clearance may leave an underlying defect unexplained.
The work involved
Establish the accessible drain route and who is responsible, then inspect the agreed runs with a camera where conditions allow. Any clearance needed first is a separate part of the scope.
Checks and next steps
Review the recorded findings, explain any visible obstruction or defect and set out the next step. A camera survey does not itself repair a damaged pipe.

About neighbourhoods and postcode matching

August 2026 ONS postcode data identifies boroughs sharing an outward district. Named centres use London Plan references; neighbourhood postcode examples use local address sources. Neither defines an exact neighbourhood boundary. Even a full postcode entered here is matched only by its first part.

Where a dedicated local service guide is available, we link to it. Other places lead to the relevant borough guide with your selected area carried into the enquiry. Your full repair address is needed when arranging attendance.

Questions about blocked drains & drain unblocking

Is a constantly running toilet the same as a blocked toilet?

No. Constant water running into the bowl usually calls for a cistern or inlet/flush mechanism assessment. Water backing up or not clearing points to a different investigation. Describe what happens so we can arrange the appropriate help.

Is the blocked drain my responsibility?

It depends on where the blockage is and which properties the pipe serves. A public or shared sewer may be the sewerage company’s responsibility. Describe the affected properties and check the responsible company’s guidance before paying for private work.

How much does toilet unblocking cost?

From £85 including VAT for call-out, assessment and labour to fix a small, safely accessible fault on the first visit where possible. We’ll give you the full visit price when you book. Parts and further work need a separate quote and your approval. If the repair needs more work, the visit charge still covers call-out and assessment.

Do you cover all of London?

Yes. We cover all 32 London boroughs and the City of London. Select a borough below or include your full postcode when requesting a quote. The appointment depends on the required work and available specialist.
