Drainage Survey Cost
Drainage surveys start from £300 plus VAT. UKDP offers CCTV, compliance, Home Buyer and Home Seller surveys, with clear pricing based on the type of survey, property size and drainage system.
How Much Does a Drainage Survey Cost?
UKDP drainage survey prices start at £300 plus VAT. An on-mains compliance survey costs £300 plus VAT, while an off-mains compliance survey costs £399 including VAT. Home buyer and home seller drainage surveys start at £399 including VAT.
For an off-mains survey, budget approximately £250 extra to have the septic tank or sewage treatment plant emptied before inspection. Larger properties and systems outside the standard scope require a tailored quote.

What Do Customers Say About UKDP's Drainage Services?
UKDP have, from my first contact with them, been very helpful, informative and re-assuring even when all hope seemed lost for a favourable outcome. Their in-depth knowledge and sheer determination made our claim possible where I feel sure most companies would have given up!
Thank you all so very much for all your work on my behalf. There is no way it was going to get done without your input. I would recommend you to anyone with similar problems. It's such a relief to have it done. Thanks again.
UKDP had been monitoring our problems with root ingress and decided the treatment plant would need replacing. They offered to manage the insurance claim, which they did very successfully. I had very little to do. Real specialists!
What Affects the Cost of a Drainage Survey?
The cost depends on the work required to inspect the property properly and provide the right level of reporting. The main factors include:
- Survey type: CCTV, compliance, home buyer and home seller surveys each cover different checks.
- Property size: Larger properties may have more tanks, chambers and drainage runs to inspect.
- Drainage system: On-mains and off-mains systems require different inspection methods.
- Survey level: Plus surveys include CCTV inspection of accessible pipework and more detailed reporting.
- System accessibility: The location and accessibility of tanks, chambers and pipework can affect the work involved.
- Tank emptying: Septic tanks and treatment plants must be emptied for an off-mains inspection, usually adding around £250.
- Additional requirements: Properties with more than six bedrooms or unusually complex drainage need a tailored quote.
What Does a UKDP Drainage Survey Look Like?
Is a Drainage Survey Worth the Cost?
A drainage survey can identify defects, compliance issues and potential repair costs before they become more expensive or affect a property transaction.
Avoid unexpected repair costs
Finding damaged pipework, root ingress or a failing off-mains system early gives you time to plan the appropriate work.
Support a property sale
Sellers can provide clear evidence about the system and address concerns before they delay the transaction.
Make an informed purchase
Buyers can understand the condition of the drainage system before exchanging contracts.
Check regulatory compliance
A survey can establish whether an off-mains drainage system meets the applicable requirements.
Plan the right work
Clear findings help prevent money being spent on repairs or replacements that do not address the actual problem.
Understand future costs
Where defects are found, UKDP provides recommendations and guideline costs to help you budget for the next steps.
Who Uses UKDP Drainage Surveys?

Ask our teamWho pays for a drainage survey when buying a property?
The buyer usually arranges and pays for a home buyer drainage survey as part of their checks before purchase. A seller may commission their own survey before listing the property or during the transaction. Who pays can ultimately depend on what the parties agree, particularly if an earlier inspection identifies a concern requiring further investigation.
Can the cost of a drainage survey be covered by insurance?
A CCTV drainage survey is normally paid for directly by the customer. Insurance may cover the cost when UKDP has been specifically appointed by the insurer. Policy excesses commonly exceed the survey cost, so customers should check their policy and speak to their insurer before assuming that the inspection can be claimed.
Does a normal building survey inspect the drainage system?
A standard building survey does not normally provide a detailed assessment of underground pipework or an off-mains drainage system. It may record visible features or recommend further investigation. A specialist drainage survey examines the relevant system more closely and provides findings that can support decisions before purchasing, selling or carrying out remedial work.
Do the drains need cleaning before a CCTV survey?
Not necessarily. A CCTV camera can inspect accessible pipework when there is a clear route through the drain. If debris, grease or a blockage prevents the camera from passing, cleaning or clearance may be required before the inspection can continue. UKDP will explain any additional work and associated cost rather than including it without discussion.
Will I receive the CCTV footage after the survey?
UKDP's CCTV drainage survey and the Plus home buyer and home seller packages include footage of the accessible pipework inspected. Plus surveys also include a detailed WinCan inspection report. Standard property surveys focus on the tank, system condition, compliance and written findings, so they do not include the same CCTV footage.
Will the report estimate the cost of any required work?
Where the inspection identifies defects or compliance concerns, UKDP explains the recommended next steps and provides guideline costs where possible. These figures help you understand the likely financial impact and plan what to do next. A firm quotation may require further information where the work is complex or the full scope cannot be established during the survey.
Does a drainage survey come with a guarantee?
A drainage survey records the condition and accessible findings observed at the time of inspection. It cannot guarantee that the system will remain unchanged or that inaccessible defects do not exist. The report will explain the survey scope and any limitations. Ask UKDP about the terms applying to the specific survey before booking if you require formal confirmation.
How much is a survey for a property with more than six bedrooms?
The published £699 price covers properties with up to six bedrooms. Larger homes can have more drainage runs, access points and system components to inspect, so UKDP provides a tailored quote. Share the property size and any available drainage information when enquiring so the required scope can be assessed accurately.
