---Blocked drain clearance costs range from £60 for a simple DIY-level fix to £500+ for an emergency call-out involving multiple drain runs and CCTV investigation. The range is wide, but most straightforward domestic drain clearances fall into a predictable price band. Here's what to expect and how to assess whether a quote is reasonable.

## Typical blocked drain clearance prices 2026

| Job type | Typical price range |
|---------|-------------------|
| Toilet or bathroom drain unblock (basic) | £60–£120 |
| Kitchen drain clearance (above-ground) | £80–£150 |
| Underground drain clearance, single run | £90–£200 |
| Emergency drain clearance (out of hours) | £150–£350 |
| CCTV survey with jetting | £200–£400 |
| Drain clearance + CCTV report | £250–£450 |
| Commercial drain clearance | £200–£500+ |

However, all prices should include VAT at 20%. Always confirm whether VAT is included in any quote.

## What affects the price

**Day or out-of-hours:** Additionally, most contractors charge a premium for evenings, weekends and bank holidays — typically 20–50% above daytime rates. Genuine emergencies (sewage backing up into the property) justify these rates. A slow-draining kitchen sink on a Sunday does not need an emergency call-out.

**Complexity:** Specifically, a kitchen sink that needs rodding from the gully outside is a 30-minute job. A drain that requires jetting from an inspection chamber, investigation of a partial collapse, and CCTV documentation takes half a day.

**Depth and access:** For example, shallow residential drains (typically 0.5–1.5m deep) are straightforward. Deep commercial or public realm drains involve different equipment and more time.

**How many runs:** As a result, a single drain run from kitchen to the main sewer is one price. A property with three separate drain runs that are all partially blocked is three times the work.

**Whether CCTV is included:** Meanwhile, some companies quote for jetting only; others include a basic camera pass; others produce a full WinCan report. Know what's included before accepting a quote.

## What a fixed-price clearance should include

Furthermore, for a standard domestic blocked drain clearance, the fixed price should include:

- Engineer attendance
- High-pressure jetting or mechanical clearance of the blockage
- Post-clearance check to confirm flow is restored
- Basic assessment of the drain condition
- VAT

In particular, it should not include hidden extras for travel time, equipment hire, or waste disposal (the water from jetting goes down the drain).

## Signs of a fair vs inflated quote

**A fair quote:**
Consequently, - Given before work starts, as a fixed price for the job
- Includes VAT explicitly
- Specifies what's included (jetting, rodding, CCTV or not)
- The engineer asks to assess before quoting and quotes based on what they find — not a blanket price given sight-unseen

**Warning signs:**
Similarly, - Very high "call-out fee" charged before any work assessment
- Hourly rate quoted with no cap or estimate
- Price escalates significantly after the engineer has arrived and "assessed the situation"
- Pressure to agree to additional works (CCTV, relining, replacement) before the clearance has even been attempted
- No written quote before work starts

**The assessment-first approach:** Moreover, reputable drainage contractors want to look at the job before giving a final price. "I'll assess on site and quote before starting" is the right answer. "It'll be £400, I can be there in an hour" sight unseen for a basic kitchen blockage is not.

## When cheap is false economy

However, the cheapest drain clearance isn't always the best value. A very cheap clearance (£50–£80) with no camera check may push a blockage further down the system without removing it. Three months later it's back, you pay again, and the pattern repeats.

Additionally, a slightly more expensive clearance that includes a camera check after jetting confirms the drain is fully clear and, more importantly, identifies any structural reason why the drain keeps blocking. A displaced joint, partial collapse, or established root ingress.

Specifically, for a drain that blocks more than once a year, a CCTV survey is the correct next step after clearance. The survey cost is typically recovered in avoided future call-outs.

## Emergency vs standard

For example, drainage emergencies — sewage backing up into the property, a blocked drain making the toilet unusable, flooding from a drain surcharge — justify emergency rates and priority attendance.

As a result, non-emergency situations — a slow kitchen drain, a gully that drains slowly after rain — are day-rate jobs. If a contractor tells you a slow drain is an emergency requiring immediate out-of-hours attendance, that's pressure selling. It's fine to wait until the next morning for standard-rate attendance.

## Getting the best value

1. Call two or three contractors for comparable prices (at least for non-urgent situations)
2. Ask for a fixed price, not an hourly rate
3. Ask what's included — jetting only, or jetting + camera pass?
4. Ask whether the price includes VAT
5. For a repeat blockage, ask for CCTV included in the clearance price
6. For a standard (non-emergency) job, book in advance rather than on the day to avoid premium rates
