Nicoll was born in the village of Islip, Northamptonshire, in 1657. He was the son of Abigail Nicoll and Matthias Nicoll, who served as the 6th Mayor of New York City from 1672 to 1673. His sister, Margaret Nicoll, was married to Col. Richard Floyd Jr., the colonel of provincial troops of Suffolk County and judge of the Court of Common Pleas and grandfather of William Floyd. Nicoll came to America in 1664 with his father and Richard Nicolls, the 1st Colonial governor of the Province of New York. His father, Richard's secretary and reportedly also his nephew, was present for the Peter Stuyvesant's surrender of Dutch New Amsterdam to the English. William was educated by his father and studied law with him.

On April 11, 1687, he was appointed Attorney General of the Province of New York. He held this office for only a year due to James II annexation of New York to the Dominion of New England on May 7, 1688. Nicoll was vehemently opposed the Leisler Rebellion and refused to surrender his commission as Justice of the Peace, therefore, Jacob Leisler imprisoned him. Nicoll was jailed for 14 months until March 1691 when Governor Henry Sloughter arrived from New York and squashed the rebellion. Upon his release from prison, Nicoll was appointed to the Governor's Council and named King's Counsel during Leisler's Treason Trial. In 1695, the Assembly sent Nicoll and Chidley Brooke, a fellow Council member, to London to urge the English government to require the other English colonies to help pay for a force to defend against the French. While traveling, Nicoll and Brooke were captured by French privateers, robbed, and he was again imprisoned, this time in St. Malo. He was eventually released and in 1701, he was elected as a member of the New York General Assembly, representing Suffolk County, serving until his death in 1723. From October 20, 1702 until May 27, 1718, when he resigned due to ill health, he also served as the Speaker of the Assembly.
