We will not put a number on this one.

listing is 'Under offer' - sale already progressing, not an actionable opportunity

Withholding a score is deliberate. A number built on missing or stale inputs would look more certain than the evidence allows.

Risks

What could kill this deal

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion

Property risk deep-dive →flood, subsidence, crime, environment - the full domain

Plan

Before you offer

1. Commission a full structural survey, not a basic condition report.
The score prices market evidence, not the fabric of the building.

Every step above was generated from a specific gap or flag in the evidence - no generic advice, no invented tasks.

T1 - Norway Maple - reduce to previous pollard points to maintain the health of the tree, we believe that this was last completed around April 2022 TPO1869
Pending

Proposed Works: Re-pollard the Willow tree, returning it to its previous pollard points in accordance with the previously approved works under Planning Application TP/2016/0512. Reasons for Works: Routine maintenance to maintain the tree's established pollard form. Reduce the weight and loading on the branches. A substantial limb failed during the summer, and the proposed works aim to reduce the risk of further limb failure. Improve light levels to neighbouring gardens and properties.
Pending
26/0558/TCA
Proposed Works: Reduce and reshape the Sorbus tree in the front garden by approximately 20% to maintain a balanced crown and improve its overall appearance. Crown raise to improve clearance from the road and create a more symmetrical crown. Reasons for Works: Improve clearance from the adjacent road. Allow more natural light to reach the property. Remove significant deadwood and maintain the tree's health, safety and amenity value.
