Seneviratne attended school at Gampaha and 1942 he obtained a certificate as an instructor from the Physical Training Institute in Ambala, India.
Following his return he gained a commission as an officer of Ceylon Engineers Corps.[3] In 1947 Seneviratne was appointed a Captain of the Ceylon Pioneers and served with the Corps when they were sent to Malaysia to oversee the construction of the railway line from Taiping to Port Weld (now known as Kuala Sepetang). While in Malayasia he played a leading part in the construction of Lankaramaya, the Buddhist Vihara in Singapore. Seneviratne claims that in 1949 he obtained a sapling of the Sri Maha Bodhi tree in Anuradhapura, which he planted at Lankaramaya. He left the army in 1950.

He was successful, polling 3,164 votes (36% of the total vote) defeating the Sri Lanka Freedom Party candidate by 359 votes.[4] At the subsequent parliamentary elections in July 1960 he retained the seat receiving 4,811 votes (50% of the total vote).[5]
He won the seat again at the 6th parliamentary elections, held on 22 March 1965, increasing his vote to 51% of the total vote.[6] At the subsequent parliamentary election, held on 27 May 1970, he was defeated by the Sri Lanka Freedom Party candidate, D. D. E. Wickremaratne, by 2,556 votes, only obtaining 43% of the total vote.[7]
Senerviratne however was successful in regaining the seat of Mahiyangana at the 8th parliamentary election, held on 21 July 1977, where he defeated the Sri Lanka Freedom Party candidate, Navaratna Banda Galketiya, by 8,801 votes (obtaining 70% of the total vote).[8]
