An enquiry for a landlord check should identify the appliance list and any additional requests. A combined booking may still involve separate inspection, maintenance and repair items.
Ask what is included and how further work would be proposed if concerns are found. Do not assume all replacement parts or remedial repairs are included in the inspection price.
These examples come from gas leak investigation and boiler service visits. They illustrate defects found during TNG’s work; they are not presented as completed landlord CP12 inspections.

An inspection found incorrect flue fall, inadequate support and securing, and an unsleeved gas pipe wall entry. The installation was classified At Risk; the article documents the findings rather than completed repairs.
See the Stevenage findings →
