How is the SE1 OfferCheck put together?

Every figure comes from official, free UK sources — Police.uk for crime, the Environment Agency for flooding, HM Land Registry for sold prices, the GOV.UK EPC register and the MHCLG Indices of Deprivation. Nothing is invented; each panel names its source.

What’s free and what’s paid?

The snapshot and the PropertyCheck IQ score are free to view. The £4.99 OfferCheck Report explains which risks matter and why; the £9.99 OfferCheck Pack adds the Negotiation Report, Solicitor Brief and Mortgage Broker Brief.

No. Sold prices are a real range with a sample size, and any projection is labelled a trend, not a prediction. We never show a single magic valuation.

Questions

About the SE1 OfferCheck

How is the SE1 OfferCheck put together?: Every figure comes from official, free UK sources — Police.uk for crime, the Environment Agency for flooding, HM Land Registry for sold prices, the GOV.UK EPC register and the MHCLG Indices of Deprivation. Nothing is invented; each panel names its source.
What’s free and what’s paid?: The snapshot and the PropertyCheck IQ score are free to view. The £4.99 OfferCheck Report explains which risks matter and why; the £9.99 OfferCheck Pack adds the Negotiation Report, Solicitor Brief and Mortgage Broker Brief.
Is this a valuation?: No. Sold prices are a real range with a sample size, and any projection is labelled a trend, not a prediction. We never show a single magic valuation.
Is this legal or financial advice?: No — it is informational only. Always confirm anything that matters with the official register and your own solicitor, surveyor or adviser.

OfferCheck is informational only — not legal, financial, mortgage, tax or survey advice, and not a valuation. Every figure is drawn from a free, official UK source and is a real range or count with its attribution, never a single guaranteed number; live third-party feeds can lag or be briefly unavailable. Always confirm anything that matters with the official register and your own solicitor, surveyor or adviser.

How our AI worksRead

Our AI analyses only the real government data we pulled for this property — HM Land Registry, the EPC register, the Environment Agency, Police.uk and the rest. It never invents figures or facts, and every panel still names its source. Its job is to read those signals together and explain them in plain English. It is an aid, not a verdict from an expert: a human should still confirm anything that matters with your solicitor, surveyor or lender.

Every panel above is a real section of the paid report — one price unlocks the whole tier. Compare the levels below.
