Swapping a tired lever or knob on an ordinary internal door is a straightforward job if the new handle matches the old latch — the same backset, and holes that line up. This guide is for a tubular latch (the common internal-door type), not for changing a lock on an external door, and not for fire-door ironmongery you have not checked.

Before you start
Safety
Stop and get a pro: If the door is a fire door (common on flat entrance doors and in shared buildings), replacement handles and latches may need to be fire-rated — check before you swap them, or get a carpenter. Do not change a British Standard lock, a euro cylinder or a mortice deadlock on an external door unless you know the standard you must meet; a locksmith is the safer call. Do not drill blindly into the frame or the wall around the door — cables sometimes run there. If you hit a cable, stop and call a qualified electrician.
- Support the handle as you undo the last screw, so it does not fall and chip the door or land on your foot.
- Keep fingers clear of the latch when you test it — the spring can pinch.
- Work with the door wedged open if it wants to swing. Do not leave a door off its role as a fire barrier in a shared building while you go to the shop.
- This is not electrical work and not a plumbing job. Leave closers on fire doors alone unless a competent person is refitting a like-for-like closer.
Prep that is worth doing
- Measure the backset: the distance from the edge of the door to the centre of the handle spindle. Common sizes exist, but you should measure yours rather than guess.
- Measure the centres of the screw holes or the size of the rose or backplate, so a new set covers the old marks.
- Note whether the latch is rounded or rectangular on the door edge, and whether the door is left- or right-hand opening if the new levers are handed.

| Item | Why you need it | Typical price | Shop link |
|---|---|---|---|
| A replacement handle set that matches the backset and hole centres | The job is simple when the new set uses the holes you already have. A set that does not match means filling and redrilling, which is easy to get wrong. | check price | |
| A new tubular latch, only if the old one is worn or the backset is changing | If the latch still snaps cleanly and the backset matches, you can often leave it in and just change the handles and spindle. | check price | |
| Screwdrivers to match the screws (usually Phillips or Pozidriv) | Using the wrong tip chews the screw heads, which you then cannot get out. | check price | |
| A tape measure and a small square or a combination square | To keep roses or backplates level, and to check the backset. | check price | |
| A pencil and a craft knife or chisel (only if the new latch plate needs a slightly different recess) | Go gently. If you have to cut a much larger mortise, that is moving towards a carpenter’s job. | check price | |
| A wood block or wedge | To hold the door still. | check price |

Step-by-step
Buy a matching set first, then take the old handles off, swap the latch only if you need to, and fit the new spindle and handles square.
Confirm you have the right replacement
Compare backset, plate size, and the spindle (usually a square bar). If the new plate will not cover the old holes, either choose another set or be prepared to fill the old holes neatly before you drill new ones.
Remove the old handles
Look for visible screws on the rose or backplate. Some roses have a small grub screw on the neck of the lever, or a cover plate that prises off to reveal the screws. Loosen the grub screw if there is one, undo the screws, and pull both handles off the spindle. Slide the spindle out.
Replace the latch only if you need to
If you are keeping the old latch, skip this step. If not, undo the two screws on the latch plate on the door edge and slide the latch out. Slide the new latch in, with the angled face of the latch bolt facing the direction the door closes, so it clicks into the keep. Screw the plate down flush. If the recess is slightly tight, ease it; if it is a long way out, stop rather than leaving a sloppy hole.
Fit the spindle and the new handles
Push the spindle through the latch. Offer up both handles, check they sit square and cover the holes, and fit the screws loosely at first. Tighten them evenly so the roses or plates sit flat and the levers return freely. Refit any grub screw onto the spindle. Do not overtighten and crush a thin door.
Check the keep and test the door
Close the door slowly. The latch should enter the keep on the frame without you having to lift or slam the door. If it catches, loosen the keep screws and nudge the plate a fraction, or slightly enlarge the recess — a little at a time. Operate the handle from both sides several times.
If something does not line up
Do not drill a second hole next to the first in the hope it will be closer. Step back, measure again, or get a carpenter. A lock that will not throw, or a handle that wobbles because the spindle is too short, needs the right part, not a longer screw forced in at an angle.
General guidance only. Check our disclaimer.
Common mistakes
- Buying a set with the wrong backset. The spindle will not meet the latch, or you will be tempted to drill a new hole in the wrong place.
- Fitting the latch bolt the wrong way round. The door will not click shut and you will slam it.
- Overtightening rose screws on a hollow or lightweight door. The door faces crush and the handle binds.
- Changing a fire-door or external lock without checking the rating. That can be a safety and insurance problem, not just a wonky handle.
- Leaving the keep where it was when the new latch sits higher or lower. The door will rattle or will not latch. Adjust the keep.

FAQ
Can I put a lever handle on a door that had a knob?
Sometimes, if the backset matches and the new rose covers the old hole. Levers put more twist on the latch, so use a decent latch and tighten everything square. If the hole is a mess, get a carpenter.
The screws just spin in the door.
The holes are worn. Use a slightly longer or thicker screw if it will not come through the other face, or pack the hole with a matchstick and wood glue, let it dry, and try again. Do not keep spinning a screw in mid-air.
What about bathroom privacy turns?
The idea is the same, plus a short privacy bolt or a bathroom lock with a coin release on the outside. Buy a bathroom set and follow the same matching rules. If the door already has a separate bolt, you may only need the handles.
My front door handle feels loose, and it has a lock in the middle.
Treat that as a lock and security job. If it is the entrance to the property, a locksmith is the safer route, especially if you need a new cylinder.
Would rather not DIY? Find a local carpenter
If the new handle does not line up, the latch mortise is a mess, or the door is a fire door or an external lock, a carpenter or a locksmith will finish it without a row of extra holes.
