What a GeoScreen report covers, how the ratings are reached, and how ordering works. If your question isn't here, email support@geoscreen.uk.
GeoScreen produces ground risk screening reports for sites in England, Wales and Scotland. Each report draws on around 30 public datasets, including geology, mining records, flood maps, radon, landfill, historical Ordnance Survey maps and borehole records. It rates 11 geohazards plus a check for groundwater protection zones, and is delivered by email in minutes.
GeoScreen is operated by Magnum GSI Ltd.
No. It is a screening report: a starting point that shows what public records say about the ground and what is worth looking into next. It is not a desk study to BS 5930 or a site investigation, and it does not replace advice from a qualified engineer. Each report sets out what it covers and what it does not.
Where a report is used to inform design, a planning submission, lending or construction, a professional desk study and ground investigation are recommended.
Both tiers run exactly the same data checks and include the same 18 figures. The difference is how much is written up.
You can see both in the sample reports.
Business and professional users: developers, consultants, architects, planners, land buyers and utility or infrastructure teams. GeoScreen is not offered to consumers, and at checkout you confirm that the order is for business use.
No. Every rating comes from fixed rules applied to the source data, so the same ground gives the same rating wherever it is and whoever orders the report. For example, a recorded landfill inside the site boundary rates Made Ground as High. The overall rating is the highest hazard rating, except that three Medium hazards together give High and two give Medium.
AI writes the narrative in Tier 1 reports from those results, within wording rules that are checked automatically, and every report passes a quality check before it is sent. AI is also used to read the historical maps for past land uses. Where a feature can be matched, its position is taken from the GB1900 gazetteer of old map labels or from OpenStreetMap rather than estimated.
A report is only as good as the public data behind it and the rules applied to that data. Every rule change is tested against a reference set of 86 reports across England, Wales and Scotland before it goes live, and practising engineers have reviewed real reports.
The ratings have not been compared systematically against ground investigation results. Intrusive ground investigation is still the only way to confirm what is in the ground.
1:625,000 is the British Geological Survey mapping that is openly licensed for this kind of use. At that scale the geology is regional, and local variations and thin deposits may not show.
To help, every report lists and links each more detailed BGS geological map that covers the site, from 1:50,000 down to the County Series six-inch sheets, so you can view or order them.
Most sources are queried live when your report runs, and the report is dated. A few large datasets are held as local copies (such as the listed building records and OpenStreetMap) and refreshed on a regular cycle.
If a source can't be reached when your report runs, the affected hazard is shown as Unconfirmed, never as Low, and we are alerted so the report can be rerun.
Each order covers a site in one country. The price is the same for all three.
Email support@geoscreen.uk with the outline or route. Larger jobs are split into report-sized sections with a summary report covering the whole site, and are quoted and invoiced rather than paid online.
England, Wales and Scotland. Each nation uses its own regulators' data, for example the Environment Agency, Natural Resources Wales or SEPA for flooding. Northern Ireland, the Isle of Man and the Channel Islands are not covered.
Most reports arrive within a few minutes of ordering: a Tier 0 usually in under a minute and a Tier 1 in about a minute and a half. Times depend on the public data services responding, so they are not guaranteed. The report is emailed to the address you give, so please check your spam folder if it hasn't arrived.
By card at checkout, through Stripe. We never see or store your card details. There are no subscriptions or accounts: you pay per report.
Before you pay, you check the pin or outline on the map and confirm it is the right site. Once an order is confirmed the report starts generating straight away, so orders can't be cancelled.
If a report is produced for the wrong site, or is materially defective, because of an error on our part, we will re-issue a corrected report free of charge or refund you. See section 5 of our Terms of Service.
The report is a screening tool to inform early-stage decisions, and it sets out its own limitations. Our liability is limited as set out in section 12 of our Terms of Service: in general, the greater of five times the fee paid or £25,000. Magnum GSI Ltd holds professional indemnity insurance.
We collect only what is needed to produce and deliver the report: the site location, your email address and your business details. The service is hosted in the EU. The report narrative is generated using Anthropic's AI, acting as our processor, and payments are handled by Stripe. Reports and order details are kept for 12 months for re-delivery and support, then deleted or anonymised.
