Every address has a history. Almost none of it is in the listing.

Old mine workings under the garden. Ground that is measurably moving. Flood likelihood the planning zone does not show. A closed landfill two streets away. All of it recorded by somebody, none of it anywhere a buyer would think to look. Our reports go and get it — every record we can reach for one address, in one place, before you commit.

USUS address

Type the address for the free ground-motion check. The full HomeGround report — motion, flood, contamination, dams, wildfire, seismic — is $19.

Screening only — not a structural guarantee. For any decision, consult a licensed geotechnical engineer.

We cover the US too — the $19 HomeGround address report, Fieldwork for farmland and the US sinking map. Flip the switch above to US.

We cover the UK too — the £19 HomeGround UK report, Tideline for the coast and five more. Flip the switch above to UK.

What each report checks

Nine things that change what a property is worth — and which report checks each.

Beyond the nine
Also in the report What each one adds that is not on the list above	Sales history since 1995 and £/m², EPC, broadband, street crime, schools with Ofsted, road and rail noise, summer surface heat.	Nearest high-hazard dam, wildfire hazard, seismic hazard, FEMA National Risk Index.	The Shoreline Management Plan policy for that frontage, epoch by epoch, and how far away it is.	Approval rates for the council and inside each designation, grid capacity nearby, PVGIS yield, LIDAR earthworks and cost.

Partly means: HomeGround UK — coastal recession appears only when the address sits on a mapped frontage, without the defence policy; planning is applications decided nearby, not designations. HomeGround US — shoreline-change rate at the nearest transect, not a 2055 / 2105 projection. Tideline UK — tide-gauge trend on coastal addresses, not combined with ground motion. Redline UK — ground hazards as one line; planning is every designation at the point plus decided renewable schemes nearby, not a general history.

Fieldwork, Landcheck and GroundTruth answer different questions — a field, somewhere to detect, a site nobody has measured — and are not on this table. They are in Full reports below.

Why trust it

It tells you when it does not know.

A screening tool that quietly reports a timed-out lookup as “nothing found” is worse than no tool at all, because you would act on it. Every check here returns one of three answers — found, not found, or could not check — and the third is never dressed up as the second. Where a search or a risk cannot be settled from any public dataset, we name it and say so.
