How to Replace a uPVC Door Handle (Step-by-Step)

Replacing a uPVC door handle is straightforward because most modern uPVC doors use through-fix bolts and a standard multipoint locking system.

Tools You’ll Need

Phillips screwdriver
Tape measure
Replacement uPVC door handle
(Optional) New spindle if not included

Always keep the door open while working to avoid locking yourself out.

Step 1: Measure Your Existing Handle

Before removing anything, take your measurements.

This is the most important stage of the process.

There are three key measurements you must check:

1. Screw Fixing Centres

Measure from the centre of the top fixing screw to the centre of the bottom fixing screw.

Common UK sizes:

122mm
211mm
215mm (very common)

If this measurement is wrong, your new handle simply won’t align with the existing holes.

2. PZ Measurement (Keyhole to Spindle Distance)

PZ stands for Profile Cylinder distance.

Measure from:

The centre of the square spindle hole
to
The centre of the keyhole

Common sizes:

92mm (most common in the UK)
68mm (often older doors)
70mm

If the PZ is incorrect, the keyhole won’t line up with your lock cylinder.

3. Backplate Length

Measure the full length of the backplate.

While less critical than fixing centres and PZ, this ensures proper coverage and a neat finish — especially if your old handle has left shadow marks.

Step 2: Remove the Existing Handle

Open the door fully.
Unscrew the two through-fix screws.
Carefully separate the internal and external handle halves.
Remove the spindle (square bar through the centre).
If the handle feels stuck, gently wiggle — never force it, as this can crack the uPVC skin.

Step 3: Check the Spindle & Lock Operation

Before fitting the new handle:

Insert the spindle alone into the lock.
Turn it manually.

If the latch retracts smoothly, your gearbox is likely fine.

If it doesn’t:

The issue may be the multipoint lock mechanism, not the handle.

This simple test prevents unnecessary replacements.

Step 4: Fit the New Handle

Insert the spindle through the lock.
Position the external handle first.
Align the internal handle.
Insert fixing screws.
Tighten evenly — do not overtighten.

Overtightening can distort the door and cause stiffness.

Test before closing:

Lift the lever
Turn the key
Lock and unlock several times

If everything operates smoothly, the job is complete.

Common Problems During uPVC Door Handle Replacement

Understanding common issues helps avoid frustration.

Handle Feels Loose After Fitting

Often caused by:

Worn spindle
Incorrect screw tension
Internal spring cassette failure

Door Only Locks When Lifted Hard

Usually indicates:

Misaligned door
Worn gearbox
Not a handle issue

Key Turns But Door Won’t Open

Often the latch or internal mechanism — not the handle.

When the Problem Isn’t the Handle

Not every stiff or faulty door requires a new handle.

Replace the handle if:

The lever has snapped
The spring has failed
The finish is heavily corroded
The backplate is cracked

Consider a gearbox replacement if:

The handle lifts but nothing engages
The door won’t lock even with a working spindle
There’s grinding or crunching inside the lock

Replacing a handle won’t fix an internal multipoint failure.
