What's my house worth?
There is no automatic valuation on this page, because no honest one can be built from Guernsey's public data. What it can do is show you every recorded sale of your property and your street since 1990, what those prices are worth at today's market level, and what comparable properties are asking per square metre. That is the evidence an agent or surveyor would start from — and you can see it before you call one.
Search by house name or street — not postcode. Guernsey postcodes aren't in the register (1 row of 41,193) and can't be resolved to a location.
What similar properties are asking, per square metre
If you know your floor area, this is the quickest sanity check available. Midpoint asking price per m² among the 106 properties currently for sale that publish a floor area — island-wide £5,899/m².

|---|---|---|
| 1-bed | £7,041 | 6 listings |
| 2-bed | £5,612 | 24 listings |

| Sark | £4,822 | 6 listings |
| Open Market | £9,163 | 26 listings |
| Local Market | £5,522 | 70 listings |
Open Market stock asks 66% more per m² than Local Market stock — two different buyer pools, and the clearest reason to know which market a property sits in before comparing anything. What the two markets mean.
These are asking prices of properties on the market now, not achieved prices — the sold register holds no floor areas, so a sold £/m² cannot be produced from it. Groups with fewer than 5 listings are left out rather than shown as a "typical" figure.
An automated valuation needs three things: what the property is, what comparable properties achieved, and when. Guernsey's register gives an address, a date and a price — no floor area, no bedroom count, no property type, no coordinates. Anyone offering you an instant Guernsey valuation from this data is modelling the gaps, and the gaps are most of it. What's on this page is the real record, plus an index that says what past money is worth now. For an actual valuation, a local agent or a RICS surveyor — several are listed under surveyors — will walk the property, which is the part no dataset replaces.
