Certificates of Authenticity

Certificates cost £10+VAT and are accompanied with a free online account giving access to a digital provenance record for the work. They can be ordered at any time directly through the platform. This cost includes our standard service (production within 3-5 working days and P&P within the UK). For deliveries outside the UK, P&P is £3.50 extra.

DNA Tags

Every tag comes with a free Certificate, provided the latter is issued after the tag has been applied to the work. Tag prices depend on the type of tag, volume and level of service.

The prices for one-off self-service tags are:

  • Paper tag + Certificate = £20+ VAT

  • Transfer tag + Certificate = £40+ VAT

  • Canvas tag + Certificate  =  £55+ VAT

We also offer a Concierge Service where we tag the works for you and manage the provenance records. There is a fee of £5 per work and a call out charge of £100 (in London: contact us for other location costs). Volume discounts are also available.

Discounts & Easy Ways to Pay
