Telscombe comprises a late 12thc. W tower and a 12thc. nave and chancel, respectively having a N aisle and N chapel. The VCH describes the chancel arch as 'a pseudo-Norman monstrosity'. The vestry is on the N side of the N aisle. The font is 13thc. and has been compared with that of nearby Piddinghoe. The church was restored in 1903 and 1922.
Telscombe is not mentioned in the Domesday Survey.
The two-bay arcade separating the choir from the N chapel has round-headed arches. The cylindrical central pier carries a square crocket capital, with keeled conical brackets making the transition from circle to square. The E respond has a similar capital on a semi-columnar respond. At its W end, the arcade rests on an apparently earlier, multi-scalloped bracket. Its necking has a rounded profile, and the under side of the plain impost block is hollowed. There are six full and two half shields on the face of the capital, and one and a half on either side. V-shaped sheaths rise between the cones. The N corner of the capital (one and a half cones), and both corners of the impost block have been replaced.
