Do you need a Subsidence Report in Hampshire?
If you’re a homeowner, a subsidence report may be needed where cracking, movement or insurer queries are linked to nearby trees. Lenders often request independent arboricultural evidence before progressing mortgages or claims.
If you’re a developer or consultant, Hampshire LPAs, insurers or structural engineers may require a subsidence report where retained trees interact with foundations, drainage or ground conditions. Early clarity avoids escalation, delays or inappropriate tree removal.
A short review usually confirms whether a full subsidence assessment is required — and just as importantly, when it isn’t.
Across Hampshire, tree-related subsidence concerns often arise where:
Clay soils coincide with mature trees near housing
Historic movement has been recorded in older developments
Trees sit close to shallow foundations or drainage
Seasonal cracking appears following dry periods
Insurers request reassurance before providing cover
Subsidence reporting helps establish evidence-based risk.
We deliver Subsidence Reports for properties across Winchester, Southampton, Basingstoke and the wider Hampshire region, supporting insurers, lenders and homeowners.
How Subsidence Survey Evidence is Tested During Planning in Hampshire
In Hampshire, subsidence-related tree evidence is scrutinised where foundation design, soil conditions and retained trees intersect. Planning officers assess whether root influence has been properly evaluated, whether soil shrink–swell risk has been addressed, and whether proposed foundations are proportionate to the actual level of risk. Subsidence reporting aligns with arboricultural guidance, NHBC principles, insurer requirements and, where planning is involved, BS 5837 and the Town and Country Planning Act 1990.
Clear evidence supports proportionate decisions without unnecessary tree removal or prolonged investigation.
