When a drain blocks, one of the first questions most homeowners ask is simple: how much is this going to cost?

Unfortunately, drainage pricing is not always presented clearly. Some companies advertise a low starting price, while additional attendance charges, equipment costs or other fees may be added depending on the job.

Fixed Price Drainage takes a simpler approach for our advertised standard residential drain-unblocking service: Fixed Price £130 + VAT — £156 including VAT.

In this guide, we explain what can influence drain unblocking costs, what customers should ask before booking, and when a drainage problem may require more than a straightforward unblock.

What Is the Fixed Price for Standard Drain Unblocking?

For work falling within our advertised standard residential drain-unblocking service, the price is:

The important phrase is standard residential drain unblocking. More specialist work may require investigation or a separate quotation.

What Can Affect the Cost of Drainage Work?

Not every drainage problem is the same. A straightforward blockage is very different from a collapsed underground pipe or a drainage system that needs to be traced.

Factors that may influence the work required include:

• Where the blockage is located
• Whether the drain is accessible
• The type and severity of the obstruction
• Whether the blockage keeps returning
• Whether underground pipe damage is suspected
• Whether CCTV investigation is required
• Whether a repair is ultimately necessary

What Is a Drain Call-Out Fee?

A call-out fee is normally a separate charge for attending a property, before the cost of carrying out the actual work is considered.

This can make comparing drainage companies difficult because a low advertised figure may not represent the final amount the customer pays.

Before booking any drainage company, it is worth asking whether the price includes attendance and what circumstances could result in additional charges.

Why Can Some Drain Unblocking Prices Look Much Cheaper?

You may see drainage services advertised using phrases such as “from £49” or “from £79”.

A starting price does not necessarily tell you what the final bill will be.

Before booking, check whether the advertised price includes:

Is a CCTV Drain Survey Included in Drain Unblocking?

CCTV drain surveys are a different service from standard drain unblocking.

A camera survey may be recommended when a drain repeatedly blocks or where there is reason to suspect a problem such as:

• Cracked drainage pipes
• Displaced joints
• Tree root intrusion
• Partial collapse
• Unknown underground drainage routes
• Recurring unexplained blockages

Drain tracing can also help establish where underground pipework runs when the route of the drainage system is unclear.

What If the Drain Needs Repairing?

Drain unblocking and drain repair are separate types of work.

If a blockage is being caused by damaged underground drainage, investigation may show that a repair is needed to address the underlying defect.

Depending on what is found, repair options may include:

Does Emergency Drain Unblocking Cost More?

Emergency drainage situations can involve very different circumstances, so it is important not to assume every emergency job falls within the scope of standard residential drain unblocking.

Situations that may require urgent attention include:

• Sewage backing up into the property
• Overflowing outside drains
• Overflowing manholes
• Multiple blocked fixtures
• Wastewater creating a flooding risk
