Floppy, spinning or snapped uPVC or composite door handle? Here's what's actually wrong.

Nine times out of ten it is a broken handle spring. Inside a modern uPVC or composite handle (anything made since about 2000) sits a small return-spring unit, the cassette, one behind each lever. Its only job is to lift the lever back up to horizontal and hold it there. The spring is steel and it works hard, so after five to ten years of daily lifting it tires and lets go, and the lever sags or flops. Older handles do the same job with a spring built into the lock body rather than a separate cassette, so a droop there usually means a swap to a modern sprung handle. The one thing to rule out is the gearbox: if a brand-new handle still droops or feels stiff, the resistance is coming from the multipoint mechanism and that is a different fix, covered on my door won't lock guide.

Almost always just the handle, and I will tell you on the phone if I think that is all you need. The handle (the lever and backplate you grip) is a separate part from the cylinder (the keyhole barrel) and the multipoint gearbox (the long mechanism down the door edge). A worn or snapped handle is from £85 fitted with a matching sprung replacement, and it does not touch your cylinder so your keys still work. On post-2000 handles I can sometimes replace just the spring cassettes for less again, a ten-minute job. The honest catch: a tired handle is often what finally breaks because it has been fighting a stiffening gearbox for months. If I find the gearbox is the real culprit I will say so rather than fit a new handle that droops again a fortnight later.

Two measurements decide it. The PZ (the gap from the centre of the keyhole to the centre of the square spindle hole) is almost always 92mm on a lever/lever handle or 62mm on some patterns. The screw fixing centres (top screw to bottom screw) are commonly 122mm on a lever/lever set, or around 212mm on a lever/pad set. The spindle itself is a standard 8mm square bar on virtually every UK uPVC and composite door. Get the PZ and the screw centres right and the new handle drops straight onto the existing holes with no drilling. I carry the common 92mm PZ / 122mm centre handles on the van in chrome, white, black and gold, so most handle swaps are a single visit. Measure yours or send me a photo on WhatsApp and I will match it.

For the part you grip, very little. Composite doors (the solid, heavier slab with the timber or foam core) use the same family of lever-on-backplate multipoint handles, the same 8mm spindle, and the same 92mm PZ as a uPVC door, so the same replacement handle usually fits both. The difference shows up in the door itself, not the handle: composite slabs are heavier, so they drop on their hinges more readily and a drooping lever on a composite is a touch more likely to have a gearbox or alignment cause underneath it. If you are not sure which door you have, the simplest tell is weight and feel. Either way, send me a photo and I will tell you what handle it takes.

A handle replacement is from £85, which includes labour and a matching sprung handle, with no separate call-out fee and no VAT on top. If your handle is a modern one and only the spring cassettes have gone, that can be less again because it is a quick part swap rather than a full handle. If the lever has snapped clean off, same price bracket, I just bring the matching set. The figure I quote on the phone is the figure on the receipt. Where I find the real problem is the gearbox rather than the handle, I will quote that separately and honestly rather than charging you for a handle that will not solve it. Full prices are on the pricing page.

Usually no, it is the handle or the spindle, and that is the cheaper end. A lever that spins freely without lifting the door usually means the spring cassette has failed or the 8mm spindle has worn round at the corners so it no longer grips the mechanism. Both are a handle-side fix. The time it points at the gearbox is when the lever lifts but feels gritty and heavy, or when you fit a new handle and it still will not lift cleanly: that resistance is the multipoint mechanism, and forcing it is how a £85 handle job turns into a £145 gearbox one. The thirty-second test I ask people to do on the phone is whether the door lifts and locks with the cylinder taken out. That tells me whether I am bringing a handle or a gearbox before I leave the van.

A lever that drops and stays down has a tired spring cassette nine times out of ten, and the quick win is that on a post-2000 handle I can often swap just the cassettes rather than the whole set, a ten-minute part change from less than a full handle. If yours is an older pattern with the spring built into the lock, the fix is a modern sprung handle from £85 fitted; your keys are untouched either way. The one thing to check before you blame the handle: have you already put a fresh handle on and it still will not spring back up? Then the lever is not the problem. Something behind it is dragging it down, and that something is the multipoint gearbox down the door edge. That is a separate job, covered on my door won't lock guide.

A handle that is stiff or hard to lift up to lock is a different problem from one that droops, and the honest answer is it usually points away from the handle itself. If the lever feels gritty and heavy as you lift it to throw the bolts, that resistance is almost always the multipoint gearbox down the door edge, or a door that has dropped on its hinges so the locking points are catching on their keeps as they go in. Both of those are covered on my door won't lock guide rather than being a handle swap. The time it genuinely is the handle is when the lift itself feels stiff or notchy in the lever even with the door open and nothing engaging: that can be a dry or damaged spring cassette binding behind the backplate, which is a handle-side fix from £85. If you are not sure which it is, the test I ask for on the phone is whether the door lifts and locks freely with the cylinder taken out. That tells me handle or gearbox before I leave the van.

Not quite, but close. uPVC and composite door handles share a common pattern, so a replacement is interchangeable as long as three things match: the PZ (the gap from the centre of the keyhole to the centre of the spindle hole, almost always 92mm on a lever/lever handle), the screw fixing centres (commonly 122mm on a lever/lever set, around 212mm on a lever/pad set), and the spindle (a standard 8mm square bar on virtually every UK uPVC and composite door). Get all three right and the new handle drops straight onto the existing holes with no drilling. Get the PZ or the screw centres wrong and it simply will not line up, which is the most common reason an online-bought handle ends up back in its box. I carry the common 92mm PZ / 122mm centre handles on the van in chrome, white, black and gold, so if you send me a photo on WhatsApp I will tell you the size and bring the right one.

A like-for-like handle swap is one of the few uPVC jobs a confident DIYer can do, and I will say so if I think you are up to it. Two screws on the inside backplate hold the set together, the spindle pushes through, and a matching handle goes straight back on the same holes. The two things that catch people out: getting the PZ and screw centres wrong so the new handle does not line up (measure before you buy), and over-tightening the through-bolts so the new handle binds. What I would not DIY is forcing a handle that is fighting a stiff gearbox, because that shears the mechanism inside the door and turns a small bill into a bigger one. If in doubt, send me a photo first.
