During the 19th century a number of attempts were made to restore the church. Between 1806 and 1811, an oak screen and the old oak benches were replaced with deal ones.
A large reading pew, with a pulpit over it, was erected in the centre of the chancel arch. The old oak roof was replaced in 1858, and the present pulpit erected in 1869.
Finally the old wooden floor, which was much decayed, and the pews, were removed in 1890/1. With the exception of the two chapels, the floor of the entire building was laid with concrete and the nave sections paved with wood blocks.
The present chancel screen was also installed during this major restoration which cost in all some £1200. Whilst the work was being carried out, services were held in the school, which was then nearby.
It was on 12th May 1891, that Edward King the revered Bishop of Lincoln, came to Harlaxton for the service of thanksgiving and re-dedication.
