Can You Replace Door Handles Without Changing the Latch?

Upgrading door handles is one of the quickest ways to refresh your home, but many people wonder if you need to change the latch at the same time. The good news is that, in many cases, you can swap handles and keep your existing latch—saving both time and money. However, there are a few details to consider to ensure a smooth, professional result.

In this guide, Door Handle Company explains when you can keep your latch, what to check before you buy new handles, and how to make sure everything fits as it should.

When Can You Reuse Your Existing Latch?

You can often reuse your existing tubular latch or mortice latch if:

The latch is working smoothly, with no sticking or stiffness.
The new handle’s spindle (the square bar that connects the handles) matches the size of your existing latch—most modern latches use an 8mm spindle.
The backset (distance from the edge of the door to the centre of the spindle hole) of your current latch suits the style and function of your new handles.

For standard UK internal doors, this is often straightforward—especially if you’re swapping like-for-like lever handles or door knobs.

Key Measurements to Check

Before buying new handles, measure the following:

Spindle size: Most UK latches use an 8mm spindle. Check your current spindle or refer to DHC’s spare spindle section if in doubt.
Backset: Measure from the door’s edge to the centre of the spindle hole (typically 44mm or 57mm). Your new handle should suit this measurement.
Learn more about backset and common sizes.
Fixing hole positions: Check if your new handles use the same screw fixing points as your old ones. If not, you may need to fill and re-drill.

If you’re changing from backplate handles to round rose handles, you might want to use cover plates or escutcheons to hide old screw holes.

When Should You Replace the Latch?

There are situations where it’s best to fit a new latch at the same time as your handles:

The latch is stiff, sticking, or loose: An old or worn latch can ruin the feel of your new handles.
You’re switching handle types: Moving from knobs to levers (or vice versa) may require a different backset for comfort and hand clearance.
You want a new finish: If you’re upgrading to matt black handles, consider a matching black latch for a seamless look.
You want extra durability: For high-traffic doors, heavy duty latches are a smart upgrade.

Door Handle Company’s latch range covers every scenario—always check product details to ensure compatibility.

Tips for a Seamless Handle Swap

Remove the old handle and test the latch with a screwdriver. If it moves smoothly and springs back, you’re good to go.
Match spindle and fixing sizes to avoid awkward installation.
Use cover plates for a neat finish if changing handle shapes or sizes.
Don’t forget accessories: If your door needs bathroom privacy or keyhole covers, check for matching options in your chosen finish.

How to Replace Handles Without Changing the Latch

Unscrew the old handles and remove them from the door.
Check the spindle—it should slide out easily.
Fit the new spindle (if supplied) through the latch.
Align the new handles and secure with screws.
Test the action—the handle should operate the latch smoothly.

If you have any trouble, refer to Ideal Home’s fitting guide for detailed steps.

When Changing the Latch Is a Good Idea

Even if your current latch works, fitting a new tubular latch guarantees maximum performance and finish match. DHC stocks latches in every backset and style, including black, chrome, and brass.

For vintage, painted, or non-standard doors, upgrading latch and handle together can deliver a more reliable and attractive result.
