Frequently asked questions.
What do the free AI credits actually get me?
Each credit points our AI at a lot you choose. In a few minutes it reads the full legal pack, scores the risk, flags hidden costs and awkward clauses, and estimates what the property is really worth — the sort of review that would cost a solicitor's afternoon. Free accounts get 3 every week, and if a lot's legal pack hasn't changed since its last analysis we refund the credit automatically, so it's never wasted.
Is it worth buying property at auction in the UK?
It can be — auction lots often sell below market value because they sell fast and as-seen, which is exactly where the margin is. The risk is that the sale is binding on the fall of the hammer with no survey or conveyancing window, so the due diligence has to happen before you bid. Below Hammer exists to close that gap: it ranks lots by profit margin and uses AI to read the legal pack and flag the risks first.
Which is the best auction site in the UK?
The big auction houses (Auction House, Savills, Barnard Marcus, BTG Eddisons and others) list the lots, but they don't tell you which lots are actually good deals. Below Hammer aggregates lots from across those houses and adds the missing layer — profit-margin ranking, AI deal scoring and AI legal-pack analysis — so you can compare opportunities in one place instead of trawling each site.
Can AI analyse an auction legal pack?
Yes. Below Hammer's AI legal pack analysis reads a full UK auction legal pack in minutes and flags tenure and lease issues, restrictive covenants, planning problems, environmental risks, special conditions of sale and hidden costs — then lists the questions to put to your solicitor. It's a screening aid that tells you which packs are worth a paid solicitor review, not a replacement for one.
Is it really free? What's the catch?
No catch. Browsing deals, AI scores and your free analyses are genuinely free — no card required. We may add premium plans later for investors who want higher limits, but the free tier is built to be useful on its own.
How is this different from Rightmove or the auction sites?
Those list properties; we do the analysis. Below Hammer ranks live deals by profit margin and layers on AI scoring, legal-pack review and exclusive local research — so you spend your time on the handful of deals worth it, instead of scrolling hundreds of listings.
Which areas do you cover?
Lots from the major UK auction houses across England, Wales, Scotland and Northern Ireland — each with local research for its area.
