In 1891, Wells married his cousin Isabel Mary Wells (1865–1931; from 1902 Isabel Mary Smith). The couple agreed to separate in 1894, when he had fallen in love with one of his students, Amy Catherine Robbins (1872–1927; later known as Jane), with whom he moved to Woking, Surrey in May 1895. They lived in a rented house, 'Lynton', (now No.141) Maybury Road in the town centre for just under 18 months and married at St Pancras register office in October 1895. His short period in Woking was perhaps the most creative and productive of his whole writing career, for while there he planned and wrote The War of the Worlds and The Time Machine, completed The Island of Doctor Moreau, wrote and published The Wonderful Visit and The Wheels of Chance, and began writing two other early books, When the Sleeper Wakes and Love and Mr Lewisham.
In late summer 1896, Wells and Jane moved to a larger house in Worcester Park, near Kingston upon Thames, for two years; this lasted until his poor health took them to Sandgate, near Folkestone, where he constructed a large family home, Spade House, in 1901. He had two sons with Jane: George Philip (known as "Gip"; 1901–1985) and Frank Richard (1903–1982). Jane died on 6 October 1927, in Dunmow, at the age of 55.

Wells had affairs with a significant number of women. In December 1909, he had a daughter, Anna-Jane, with the writer Amber Reeves, whose parents, William and Maud Pember Reeves, he had met through the Fabian Society. Amber had married the barrister G. R. Blanco White in July of that year, as co-arranged by Wells. After Beatrice Webb voiced disapproval of Wells' "sordid intrigue" with Amber, he responded by lampooning Beatrice Webb and her husband Sidney Webb in his 1911 novel The New Machiavelli as 'Altiora and Oscar Bailey', a pair of short-sighted, bourgeois manipulators. Between 1910–1913, novelist Elizabeth von Arnim was one of his mistresses. In 1914, he had a son, Anthony West (1914–1987), by the novelist and feminist Rebecca West, 26 years his junior. In 1920–21, and intermittently until his death, he had a love affair with the American birth control activist Margaret Sanger. Between 1924 and 1933 he partnered with the 22-year younger Dutch adventurer and writer Odette Keun, with whom he lived in Lou Pidou, a house they built together in Grasse, France. Wells dedicated his longest book to her (The World of William Clissold, 1926). When visiting Maxim Gorky in Russia 1920, he had slept with Gorky's mistress Moura Budberg, then still Countess Benckendorf and 27 years his junior. In 1933, when she left Gorky and emigrated to London, their relationship renewed and she cared for him through his final illness. Wells asked her to marry him repeatedly, but Budberg strongly rejected his proposals.
In Experiment in Autobiography (1934), Wells wrote: "I was never a great amorist, though I have loved several people very deeply". David Lodge's novel A Man of Parts (2011)—a 'narrative based on factual sources' (author's note)—gives a convincing and generally sympathetic account of Wells's relations with the women mentioned above, and others.
Director Simon Wells (born 1961), the author's great-grandson, was a consultant on the future scenes in Back to the Future Part II (1989).
