Drainage and septic tanks

The property is in Scotland and has a septic tank. Why must you not apply England's general binding rules as if they were the Scottish rule?

You must not apply them because England's general binding rules are not the Scottish rule for this tank. The property is in Scotland. Copying an English discharge regime onto it treats the wrong system as if it were local law. The survey recorded the septic tank it could see. It has not decided compliance with Scottish controls and it has not applied the English rules. A Home Report is the Scottish selling product. It is not an English Level 2 or Level 3, and it does not convert those English rules into Scottish ones.

What is the fuller explanation?

A septic tank settles sewage. It is not a cesspool, which only holds sewage until it is emptied, and it is not the same as a treatment plant. Whatever the type, the legal rules follow the country. England's general binding rules describe an English route for small discharges. Scotland regulates those discharges under its own controls. The survey did not register the tank, did not sample the outfall and did not measure any set-off. It only notes what was visible.

Ask the Scottish solicitor which permission or registration, if any, applies to this tank, and for any paperwork the seller holds. Do not send an English general-binding-rules checklist as if it answered the Scottish question. A drainage specialist can describe condition. The survey has not said the tank passes or fails a rule, and it has not told a lender that an English regime was met. Keep the legal question on the Scottish side of the file.

What should you ask your surveyor?

What paperwork exists for this tank under Scottish controls?
Did the visit only see the tank, rather than test the outfall?
Why is a Home Report not an English Level 2?

What are the typical next steps?

Ask the solicitor which Scottish permission applies to this tank.
Do not use England's general binding rules as the local test.
Keep any drainage specialist's note separate from the survey.

Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.

Also asked about this

Is a Home Report just an English Level 2 with a different cover?

No. A Home Report is the Scottish product. It is not an English Level 2 or Level 3. This page does not invent how long a Home Report lasts. Using one, or a survey, does not let you paste England's general binding rules onto a Scottish septic tank. The tank still has to be read under Scottish controls, which this inspection has not applied.

Has the survey emptied the tank and judged how it treats sewage?

No. The survey recorded a septic tank in Scotland and has not emptied it, sampled it or decided a treatment result. Emptying and sampling are specialist steps. What was seen is not a test of performance, and it is not an application of England's general binding rules. Condition and legal registration remain separate questions.
