How we check

How we check our figures

What our numbers mean, where they come from, and what we do when we get something wrong.

Planning ranges, not quotations

Prices move quickly, especially rent. Every figure here is a planning range, not a quotation. Check current listings before you decide anything.

Prices vary by region, season, brand, pack size, promotion and branch. A figure in one of our episodes is a starting point for your own checks. Unless we say otherwise, we assume one adult living long term, with no car, no children and no major debt.

Official sources first

We build figures and rules from official sources wherever they exist, and each episode guide lists its sources. Sources cited across the series so far include:

  • BOE, Spain’s official state gazette, for the law itself (including the Urban Leases Act and the 2023 Housing Law)
  • INE, the National Statistics Institute (consumer prices and the IRAV rent index)
  • Ministry of Housing (State Rental Housing Reference System)
  • Ministry of Agriculture, Fisheries and Food (food consumption and price reports)
  • Ministry of the Interior and the government immigration portal
  • Agencia Tributaria, the tax agency
  • Banco de España (banking customer information)
  • DGT, the traffic authority (low-emission zones)
  • Spanish Data Protection Agency, the European Consumer Centre Spain and the European e-Justice Portal

Where a figure is a shop price, such as a supermarket basket, it comes from the retailer’s own website.

What our dates mean

Each episode guide shows the date its figures and rules were checked. That is the date of the research, not the date you’re reading, and things may have changed since. Where we recheck something later, we say what we rechecked and when.

Corrections

We can’t change the footage in a published video, so when we get something wrong, we record it here.

  • Episode 5 · The Best Place to Live in Valencia Isn’t Where You Think At 1:31, a clip of Madrid’s Sol metro station appears in a video about Valencia. It shouldn’t be there; we missed it in the edit and final review. Thanks to the viewer who spotted it.
