A Bespoke LED Standing Light Box starts at £99, and size is the main thing that moves it from there. A compact doorway or reception sign sits near the entry price; a large foyer piece built to read across a hall costs more, because it uses more panel and more LED. The other price factors are the finish and whether you want one unit or a matched set across sites.
The comparison worth doing is owning against hiring. Hired event signage comes back re-billed every event, often late and scuffed, whereas an owned box is a one-off cost that turns up ready every time you use it, which for anyone doing regular events pays for itself fast. Runs over £1,000, say a set for several branches, bring in preferential trade pricing.
Every box includes a free mock-up so you approve the exact size and artwork before paying, with GBP, USD and EUR pricing and worldwide delivery. See yours lit and priced on a free mock-up.
