Do gas vehicles need inspecting every year?

Last updated: 7 Nov 2026

Yes. LPG and NGV vehicles need an annual inspection certificate to renew road tax. Factory-fitted CNG vehicles start from year 4. We handle the gas inspection, vehicle inspection, compulsory insurance and tax renewal in one visit. See our gas inspection page.
