What Changes a CCTV Drain Survey Quote in London

A quote for a CCTV drain survey can look very different from one home to the next. The price moves because the job moves. This guide explains what changes a quote, so you can compare offers fairly.

For the actual £ ranges, read our CCTV drain survey cost guide for London. This post explains why those figures spread out, since the range is wide.

Pipe length and the number of drain runs

Length can be the biggest driver. A short run from a flat to the sewer takes little time. However, a long garden run, or several separate runs, takes much more.

More pipe means more time on site and more footage to review. It can also mean a longer written report. Therefore, ask how many runs the quote covers.

A surface water drain is often a separate run. A quote that leaves it out is not the same job as one that includes it.

Access to chambers and manholes

Every access point adds time. Some are easy to open. Others sit under paving, soil or a shed, so finding them takes time.

If a lid is buried or stuck, the engineer may need extra time to find it and lift it. For example, a chamber that has not been opened for years can be hard to shift. Ask whether a quote allows for this.

Basements add another layer. A drain may run deep below ground level, and the route to it may be tight. You can read more about this in our guide to CCTV drain surveys for basement conversions.

Push-rod camera or crawler

A push-rod camera can survey many house drains. The operator can feed a flexible rod with a camera head along the pipe. It suits small pipes and short runs, while a crawler suits larger ones.

A crawler is a small motorised vehicle that carries the camera. It can be used for larger pipes and longer runs. Because it needs more kit and more time, it may cost more.

So the equipment tells you something about the job. If a quote does not say which method it assumes, ask.

Survey, inspection or a full report

Scope matters as much as pipe length. A full CCTV drain survey can cover every accessible run. A targeted drain inspection can look at one section, such as a drain that keeps blocking.

A narrower job costs less, but it also answers fewer questions. If you need the full picture, a partial look can cost you more in the end, since you may pay twice. Our guide to survey versus inspection helps you choose.

Extras change the quote too. For instance, sonde tracing, a drainage plan or a report set out for a solicitor all add work.

Flat rate or per metre

Some quotes give one flat price. Others charge by the metre. A per-metre price can look cheap at first, yet it rises with every extra metre of pipe.

Because you do not know the length before the camera goes in, a flat rate is easier to compare. In contrast, a per-metre rate only works if you know the total length. Ask for the quote in writing, and ask what happens if the run is longer than expected.

London access and report timing

Access in the capital can be harder than elsewhere. Parking limits, narrow streets and shared yards all take time. Meanwhile, older drains in Victorian streets often have extra branches and shared sections.

Report timing can also shift a quote. Specifically, if you need the report quickly, say so when you ask. Do not assume a fast report is included.

Your location and your reason for the survey

The same drivers apply across Greater London. Basements and shared drains raise questions in Camden, while garden runs and the number of chambers may matter more in Croydon. See our drain surveys in Camden and drain surveys in Croydon pages.

The picture is similar for drain surveys in Kingston. The same goes for drain surveys in Sutton. The details of the property decide the quote, not the postcode.

Your reason also counts, because a buyer needs a report that suits a solicitor. Read The Right Drain Survey for an Older London Home if that is you.

Questions to ask before you accept

Use this short list to compare quotes:

• How many drain runs does the quote cover?
• Is the price a flat rate or per metre?
• Which camera method does it assume?
• Does it include footage and a written report?
• Does it cover tracing or a drainage plan?
• What happens if access is harder than expected?

A good answer to each one tells you what you are buying. Yet a vague answer is a reason to ask again.

What to do with the result

A WRC-standard survey report grades defects from 1 to 5, where 5 is the most serious. Our guide to MSCC5 grades and what they mean explains how to read them. If you plan to buy, see whether a house survey checks the drains. If the report finds a defect, read what to do after the drain survey.
