How ParkingVerified verifies
Every rating, price and claim on this site carries the date we last checked it. This page explains where the data comes from, how rankings are computed, and how to challenge anything we publish.
Independence
ParkingVerified accepts no paid placement. No operator can buy a position, a modifier or a kinder verdict, and no operator is told about its ranking before publication. When affiliate links are introduced (see the disclosure below), they will never influence rank, rating or wording — the ranking is computed before any commercial relationship is considered.
Data sources
Every figure we publish is taken from a named public source and recorded with its score, review count and the date we read it:
- Google Business Profiles — rating and review count for each operator.
- Trustpilot — rating and review count where an operator has a profile.
- Verified-booking reviews on Parkos and ParkVia — platforms that only accept reviews from completed bookings.
- Official published tariffs — including Aena’s parking prices for the official airport car parks, and each operator’s own published price list.
Nothing is estimated, and we do not write reviews ourselves.
Ranking criteria and weights
Positions in a guide are scored on four weighted criteria:
- Value — 30%. Day and week prices against the market for the same transfer type, including what the headline price excludes.
- Security — 25%. Fencing, camera coverage, staffing hours, covered options, and whether you keep your keys.
- Transfer speed and reliability — 25%. Real door-to-terminal time: walking distance, shuttle frequency and hours, valet handover terms.
- Reputation — 20%. Public review scores weighted by review volume and recency across the sources above.
The “Best …” modifier on each entry names the use case the operator wins; it never overrides the weighted score that sets rank order.
Verification cycle
Each fact carries a visible “checked” date. Our build system flags any rating older than six months, and flagged entries are re-verified before the guide is republished. If a price or service changes between checks, the dated figure tells you exactly how current our information is.
Inclusion and exclusion thresholds
Our guides are curated, not exhaustive — absence from the site can be deliberate. To be listed, an operator needs a published price list, a reachable booking route and a public review record large enough to judge (as a rule of thumb, at least 100 reviews across our sources).
Where we flag an operator negatively, the grade is derived purely from attributed third-party data using this published formula: the count-weighted mean of its public review scores, normalised to a 5-point scale, maps to a letter — A ≥ 4.3, B ≥ 3.8, C ≥ 3.3, D ≥ 2.5, F < 2.5. Sources with no numeric score are excluded from the calculation and shown for context only. A negative pattern must be evidenced across multiple platforms and multiple years with a large sample; individual reviews never qualify on their own.
Red flags for travellers
Patterns worth knowing regardless of which operator you choose, especially for valet and meet & greet services:
- Photograph the car — including the odometer and fuel gauge — at handover.
- Insist on a stamped or signed receipt naming the operator.
- Confirm the company collecting the car is the one you booked, not a subcontractor you have never heard of.
- Be wary of prices dramatically below every competitor; storage conditions or insurance are usually the difference.
Corrections and right of reply
Operators and readers can challenge anything we publish at corrections@parkingverified.com. We respond within five business days. Where an operator disputes a figure, we re-verify against the named source; where we flag a negative pattern, the operator is contacted before publication and any response is published alongside our summary.
Affiliate disclosure
ParkingVerified currently contains no affiliate links. If that changes, affiliate links will be clearly disclosed on every page that carries them, and they will never affect how any operator is ranked, rated or described — see the independence statement above.
