Valuation — A field study
glassguidevalue.com is built for the trade side of UK vehicle data. The same lookups that sit behind retail checks, exposed at a pace that suits a forecourt or auction lane rather than a customer reading on a phone. Glass guide-style UK car valuations. Know what dealers, auctions and forecourts really pay.
Data sourced live from DVLA, MIAFTR, PNC and the UK lender register at lookup time.
Typical lookup completes in under one second from the UK.
Built and supported in the UK as part of the trade-facing side of the network.

Values are derived from a rolling window of UK transaction data — auction hammer prices, dealer trade-in figures and listed private adverts — not from a single annual reference book. The window is short enough that a sharp market shift, for example after a fuel duty change or a high-profile model recall, is reflected within days rather than months.
Selling privately through a classified site typically lands between the private and retail figures. Trading in at a franchise dealer typically sits below the trade figure once preparation costs are deducted. An auction lane will sit at or slightly below the trade figure depending on time of year. The report's value figures are not predictions of any single transaction.
A clean check confirms that, at the moment of lookup, no UK insurer has filed a total-loss marker, no lender has registered an open agreement and no police force has reported the vehicle stolen. It does not confirm mechanical condition, repair quality, or work carried out in cash and never declared to an insurer. Treat the report as the legal and financial backstop to an in-person inspection, not a replacement for one.
/ Brand consolidation
glassguidevalue.com has consolidated into Expert Car Check, the UK valuation and history service many of its users already cross-referenced. The data sources are unchanged: DVLA's vehicle record, DVSA's MOT history, MIAFTR for write-offs, the Police National Computer feed for theft markers and the UK lender register for outstanding finance. The team, the underwriting partners and the support contact are the same. What's changed is that the work that was previously spread across several smaller brands now sits in one place, which keeps response times tight and the underlying registers maintained against current DVLA schemas. Bookmarks and historic links to glassguidevalue.com continue to resolve here. If you were referred to glassguidevalue.com by a previous report, broker or print listing, this is the right page — there is no further redirect to chase.

Trade is what a dealer pays another dealer or auction. Retail is the advertised forecourt price after preparation. Private is what a typical private seller actually achieves, sitting between the two.
Yes. A Category S or N marker typically reduces market value by 20-40% on equivalent unmarked cars, depending on make, year and the visible quality of the repair.
It's a forecast, not a guarantee. Confidence is high for high-volume models with thick transaction histories and lower for rare specifications. The forecast is shown as a range rather than a single number for that reason.
Different services use different datasets, different definitions of trade vs retail and different update cadences. A 5-10% variation between two reputable services on the same vehicle is normal.
