Free house valuation Northern Ireland: Derry postcode guide

Free house valuation Northern Ireland: what you get

House Price Derry gives homeowners in BT47, BT48, BT49 and BT82 a free, private guide range before they invite an estate agent or surveyor to the property. The service covers Derry and the North West rather than every Northern Ireland postcode.

The postcode and property type place your home in a local guide. Entering a house number does not mean we have found a recorded sale for that address. Your report explains the source match and the data period actually used.

Enter your name and email before the valuation range is shown. Your report is also sent by email. A sales call or estate-agent contact is a separate optional choice.

How to use the house value calculator by postcode

Enter the real postcode, house number and property type. A terrace, semi-detached home, detached home and apartment can behave differently inside the same postcode, so use the property as it stands today when adding bedrooms, condition, parking, garden and garage details.

To request your report and a House Price Derry follow-up, provide your first name, email and phone number. HPD will contact you about the valuation and your next steps. There is no obligation to sell. A named estate agent only receives your details through a separate partner-widget request.

House Price Derry provides a market guide, not a formal RICS, mortgage, tax or legal valuation.

Use current official Northern Ireland data

The Q2 2026 Northern Ireland House Price Index put the average property price at £202,487, up 9.2% over the year. Derry City and Strabane had a lower average of £189,474 but stronger annual growth of 12.4%.

Those averages describe completed-market movement across broad areas. They are useful anchors, not the value of one address, and the latest figures remain provisional.

Is a free online house valuation accurate?

An online house valuation is most useful as an informed range for early planning. Its quality depends on how closely the available local evidence matches the property and whether important features have been entered accurately.

Unusual land, major extensions, exceptional condition, restricted access or a thin local comparison set can all make an automated range broader. That is why the report shows the source period and why the result should not be treated as a guaranteed sale price.

Read the range and source period together

The midpoint is not a guaranteed sale price. Read the low-to-high range, the data period and the explanation together so you can see whether the estimate is closely anchored or based more heavily on an area guide.

Keep the estimate date if you are using it for planning. Official data is updated and buyer demand changes, so an online result is a snapshot rather than a permanent value.

When an online estimate is not enough

Ask for an in-person appraisal when you are preparing to sell, the property has unusual land or alterations, or the range is too broad for the decision. Mortgage, tax, legal and formal valuation work needs the appropriate qualified professional.

A free online guide can help you form the first question. A qualified professional should handle any decision that needs a formal valuation or advice on the specific property.
