How to Replace Internal Door Handles and Latches

Swap worn or loose interior door handles and latches in a UK home, including measuring backplate and latch size, matching fixings and fixing a handle that droops.

Door handles take more daily wear than almost any other fitting in the house. They loosen, droop, stop returning the latch or simply look dated. Replacing them is a quick, inexpensive job that changes how a whole room feels. The main trick is knowing what you have before you shop.

First, see if it just needs tightening

Many "broken" handles are only loose. Before replacing anything:

  1. Look for a small grub screw on the side of the handle, near the rose. Tighten it with an Allen key.
  2. If there is no visible screw, look for a small catch or hole in the rose. Press it with a pin or a small screwdriver and pull the rose away to reveal the fixing screws.
  3. Tighten those and check whether the handle still droops.
  4. If the spindle is worn or bent, or the return spring has failed, replace the handle set.

A handle that is loose on the spindle may also be down to the wrong spindle length, which is a replacement job.

Know what you are replacing

Common interior types:

  • Lever on a rose. A circular rose on each side, with a lever handle operating a latch.
  • Lever on a backplate. A long plate with the handle at the bottom, often with a keyhole or bathroom lock.
  • Latch only. A handle set with a standard latch, no locking.
  • Privacy set. For bathrooms and bedrooms, with a thumb turn on the inside and an emergency release outside.
  • Lock. For doors with a mortice lock, the handle is separate from the lock.

Decide what you want before buying: latch, bathroom privacy, or lock.

Measure

  • Latch backset. The distance from the edge of the door to the centre of the spindle. The common sizes are 44 mm and 57 mm.
  • Latch length. Typically 64 mm, 76 mm or 100 mm tall, but check.
  • Backplate size and hole spacing, if using a plate. Measure the distance between the screw holes and the centre of the spindle.
  • Door thickness. Most internal doors are 35 mm thick, but older ones may be different.

The simplest approach is to remove the old handle and take it to a shop, or take clear photos with a tape measure.

What you will need

  • Screwdriver and Allen key
  • New handles and latch, if replacing the latch too
  • Chisel and mallet if the latch recess needs adjusting
  • Pencil and tape measure

Step by step

  1. Open the door and remove the old handles. Release the roses, undo the screws, remove the handles and spindle.
  2. Remove the latch. Undo the two screws in the door edge and pull out the latch. Keep the old one for reference.
  3. Fit the new latch. Push it into the recess, check the orientation so the sloping face of the latch faces the closing direction, and fix with screws.
  4. Insert the spindle and handles. Slide the spindle through the latch, fit the handles on both sides and tighten the screws.
  5. Fit the roses or backplates. Press them into place and secure.
  6. Check the keep. Close the door and make sure the latch engages the keep without catching.
  7. Adjust if needed. If the door rattles or sticks, adjust the keep or see how to fix a sticking door.

Common problems

  • New handles do not fit the old holes. Adjust by choosing a different backplate or filling and re-drilling holes, with the right bits.
  • Handle droops. The spindle may be too short, or the return spring is weak. Try a different brand or sprung handle.
  • Latch jams. The recess may be too tight, or the faceplate is not flush.
  • Mismatched finish. Buy matching sets of latches, hinges and handles for a tidy result.

Fire doors and bathrooms

On fire doors, avoid cutting large holes or replacing hardware with non-certified fittings, as this can affect fire performance. If in doubt, ask a competent person. In bathrooms, choose a privacy set with an emergency release.

If you are a tenant

Keep the original handles in a labelled bag. If you want to change them, ask permission first; see handyman work in rented homes.

Frequently asked questions

Can I replace just the handle and keep the latch?

Often yes, if the spindle fits. Check that the new handle is compatible with the existing latch and measure the backset.

Why does my handle keep working loose?

The grub screw may be loose, the spindle is the wrong length or the door is heavy and the handle is flexing. Tighten and, if needed, replace.

Are all door handles interchangeable?

No. Sizes and fixings vary, so measure and check compatibility before buying.
