How Much Does a CCTV Drain Survey Cost?

What a drain survey shows that a house survey cannot

A RICS Level 2 or Level 3 surveyor lifts inspection chamber covers where they can and looks in. They do not run a camera through the pipes. A CCTV drain survey does: a technician feeds a camera along every accessible run and records cracks, displaced joints, root ingress, collapsed sections and misconnections, then maps the layout. The full version comes with a written report and the footage, which is what you need if you intend to negotiate or claim on insurance.

Drainage problems are expensive precisely because they are underground. MyJobQuote's guide puts a drain line repair at around £850 and a new soakaway at £500 to £1,000, and a full collapse under a driveway costs far more. Against that, £250 to £350 for a homebuyer survey is cheap.

When a buyer should order one

• Pre-1950 property, where clay pipes and old joints are common.
• Mature trees within a few metres of the drain runs, especially willow, poplar and oak.
• The survey or your own viewing notes damp at low level, gurgling, slow drains or a persistent smell.
• Any sign of ground movement: cracked paths, sunken patios, hollow-sounding areas near manholes.
• Extensions built over or near old drains, where build-over consent may never have been obtained.
• You want the drains insured. Some insurers will not cover pre-existing defects, so a clean survey at purchase protects a later claim.

Shared and public drains

Since 2011 most shared drains and lateral drains outside the property boundary in England and Wales belong to the water company, so a defect there is its problem rather than yours. Your solicitor's drainage and water search confirms whether the property is on a public sewer and where the boundary of responsibility falls, but it does not inspect the pipes. The two documents answer different questions.

If the property is on a septic tank or treatment plant rather than mains drainage, a camera survey of the pipework is only half the job; the tank itself needs inspecting. See the guide to sewer connection cost if you are weighing a connection to the mains.

How to save

• Ask for a homebuyer survey with a written report, not a basic look-and-see. The cheaper version gives you no evidence to negotiate with.
• Confirm the price includes footage and a drainage plan. Both Checkatrade and MyJobQuote list these as what separates the £275 average full survey from the £160 basic one.
• Ask whether jetting is included or extra. MyJobQuote and homecosts both flag it as a common add-on of £100 to £150.
• Get the excavation risk quoted up front if there are no visible inspection chambers; locating and digging to a drain adds £100 to £300.
• Use the report. A written defect list with repair estimates is a direct price-reduction argument that most sellers accept rather than lose the sale.
