House valuation without email: free online estimates explained

You can get a house valuation without email if what you want is an online estimate rather than a visit. An online estimate is built from data: recent sold prices nearby, adjusted for how the market has moved. A valuation by an estate agent or surveyor involves a person looking at the home, so they need a way to reach you. Many people searching for a free valuation want the first kind and get asked for the second.

We only report what each page said when we read it on 31 October 2026.

• Rightmove's Instant Online Valuation page described starting with a postcode and choosing an address. Email valuation alerts were an opt-in, and refreshed valuations are viewed in a My Rightmove account when you log in.
• Zoopla's home values page said to "input your address and some basic details about your home". It did not say whether an email or phone number is required. It also offered to connect you with local agents to discuss the figure.
• Your Move's valuation page described a free valuation appointment that "usually takes around an hour", booked with "some contact details", with the estimate given after the visit.

We could not load Springbok's site on the day, so we say nothing about it.

The pattern is simple. Instant estimates can work from an address alone. A valuation that involves a visit needs contact details because someone has to arrange it. Neither is wrong, but know which one you are asking for.

We test ours every month against real sales it had not seen. In the July 2026 backtest we took 600 standard market sales and built each estimate using only sales and index figures that existed before the sale. The results:

• The typical error (median absolute percentage error) was 12.2%. In June 2026 it was 11.8%.
• 41.7% of estimates landed within 10% of the price paid, and 70.2% within 20%.
• The price paid fell inside our range 75.8% of the time, so about one sale in four landed outside it.
• Flats were the hardest type that month, with a typical error of 15.7%. Semi-detached homes were the easiest, at 10.6%.

Those are honest numbers, and they show the limit of any estimate built from postcode and property type. Our accuracy page explains the method in full.

The big portals say similar things about their own figures. At the time of checking, Rightmove said its estimates "are more accurate for properties which are typical of their area", that it "can't take into account the quality of the interior of your home", and that it "isn't the same as an estate agent's valuation". Zoopla told readers to "treat the estimate as a starting point rather than a final figure" and said "algorithms cannot account for a property's condition, features or recent improvements."

If the estimate is the first step towards a sale, our sell a house fast guide covers the routes, and the sale method comparison shows them side by side.

For a wider look at the street, our free property checker adds sold history, EPC and flood risk with no email either. Our guide on how to find out how much your house is worth covers the manual route through sold prices.
