House prices calculator
Plenty of sites have free online calculators to help get a valuation, but sometimes they’re really inaccurate.
Zoopla, Property Price Advice and Mouseprice are the most accurate, apparently.
Zoopla’s is totally free and offers a bespoke valuation based on data, but be warned that it doesn’t take into consideration renovations and a number of other factors.
Property Price Advice’s offering is really quick and easy but will probably overvalue your property, and Mouseprice will charge you £20 for a full valuation (and it still might not be accurate).
