How Much Do Trouser Alterations Cost in London?

Trouser alterations are some of the most frequently requested tailoring jobs in London — and some of the most worthwhile. A well-hemmed pair of trousers or a properly tapered leg transforms how a garment sits on the body. Here is a transparent breakdown of what trouser alterations typically cost.

What Affects the Cost?

• The finish required. A basic hem takes minutes. A same-finish hem — matching the original chain stitch or turn-up exactly — takes significantly longer and requires the right equipment.
• Fabric type. Delicate fabrics such as silk trousers or fine wool require more care and time than standard polyester or cotton blends.
• Number of seams. A 2-seam taper works the inner seams only. A 4-seam taper works all four seams for a more dramatic result — naturally more time and cost.
• Original features to preserve. Preserving belt loops, pocket styles, or turn-up detail adds complexity and time to the alteration.

Is It Worth Altering Trousers?

Almost always, yes. A £25 trouser hem on a £180 pair of suit trousers is a straightforward investment. A £18–28 taper on a pair of chinos you wear three times a week is excellent value.

The exception is very cheap garments where the fabric is so poor that the alteration costs more than a replacement. But for any trousers you wear regularly and want to keep wearing, a professional alteration is worth every penny.
