What to include for a technical correction

Please include the page URL, the wording or calculation you believe is wrong, and ideally a link to the current official source. We prioritise errors that could materially change a planning result.

Site-specific design requests: SepticSpec is not an engineering consultancy or regulator. We cannot approve a drainage field, issue a permit or substitute for Building Control / regulator advice.
