That is a very surprisingly jaded take on the aid that the UK has supplied, and in my opinion incorrect. As per the details outlined here[0], the UK has supplied the following in military aid alone (see linked article for financial, and humanitarian aid).
> Trained 22,000 Ukrainian troops since 2015 as part of Operational Orbital
> Delivered 20 armoured vehicles since 2015.
> Delivered "thousands" of NLAW anti-armour weapons (~£20,000 each)
> Sale of two Sandown-class minehunters.
> £1.7bn agreement to support the acquisition of eight missile craft and one frigate.
> Deployment of RC-135W Rivet Joint surveillance aircraft to provide information on size and position of Russian forces.
> Unspecified further military aid, on 28 February 2022.
> ISTAR (intelligence, surveillance, target acquisition, and reconnaissance) support, both standalone and in partnership with the US.
