Let us start with what manufacturers dislike hearing: on Trackman, the performance gap between a 2021 driver and a 2026 one averages two to four metres of carry. That is less than you gain from the right shaft or two extra degrees of loft. If your old driver fits you, do not replace it just because a new one exists.
Wedges are a different story. Grooves wear and spin falls off roughly in proportion to shots hit. Our own in-store measurements show a wedge losing 15 to 20 per cent of full-shot spin after about 70 rounds. In practice, the shot that used to stop now runs three metres past the flag. At 30 rounds a year, change wedges every two to three seasons.
Irons last longest because a stainless head is very hard to destroy. What does wear out are the grooves in the short irons and the grips. If your 7-iron flies the same distance it did five years ago and you have no reason to change lofts, carry on playing them.
The signs that genuinely mean replacement: a visible crack or dent in a driver face (usually announced by a change of sound and a sudden drop in ball speed), a loose hosel, rust in iron grooves, or a composite shaft with damaged lacquer.
The second category is changes on your side. If you have gained or lost ten kilos in two years, changed your tempo, or gone from 30 handicap to 18, clubs that once fitted probably no longer do. Lie and length can be adjusted; shaft stiffness cannot.
Inherited clubs deserve their own paragraph. A set from your father, or bought secondhand, is typically an inch too long, two degrees too flat, and stiffer than you can load. We have seen dozens of players drop five shots off their handicap purely by moving to clubs of the correct length.
If you are weighing it up, bring the clubs to us on Galvaniho. We measure loft and lie on every head, check groove depth with a micrometer, and tell you what is worth fixing and what is worth replacing. The diagnostic is free and takes about twenty minutes. We also buy old clubs, and you can get a rough figure from our trade-in calculator first.
