My wife and I are FTBs in Oxfordshire who recently had our survey report back with a few minor points.
One point which neither of us have the first clue about was regarding the property's drainage. Specifically, it noted that the inspection chamber access in the garden has become seized and that it is recommended that a drainage survey is carried out prior to exchange.
Is this something that is written on all surveys or is this something that is important to have done?
The relevant part of the report reads:
The property is believed to be connected to mains drainage system. Where access could be obtained, the underground drains were clear with no evidence of any blockage.
No accessible inspection chambers were noted within the grounds of the property at the time of our inspection.
An inspection chamber was noted to the rear garden however the lid has become seized, and was unable to be lifted.
Without extensive exposure work or a CCTV inspection, we cannot confirm the layout of the underground drainage system. The National Association of Drainage Contractor's (NADC) recommends that you instruct a drainage survey to be carried out by a certified NADC drainage contractor, prior to exchange of contracts to confirm its condition with all recommendations implemented.

Your legal advisers should make the usual conveyancing checks and searches in respect of the drainage system.
