How to Identify uPVC Window Handles: A Complete UK Guide

Choosing the right replacement uPVC window handle starts with identifying what lock and handle you need. Whether your existing handle is broken, outdated, or you simply want a style refresh, understanding the different types is the first crucial step. Getting it wrong can mean wasted time, money, and the frustration of ordering an incorrect replacement.

This guide will walk you through the three most common uPVC window handle styles you'll encounter in UK homes: Espag, Cockspur, and Tilt and Turn. We'll explain how to identify each type, what measurements you need, and where they're typically found. Once you've identified your handle type, you can easily browse our extensive selection of uPVC window handles to find the perfect match for your needs.

Let’s get started.

Espag Handles: The Most Common Choice

Espag handles (short for espagnolette) are the most prevalent type found on modern uPVC windows manufactured from the 1990s onwards. They are easily recognisable by several distinctive features:

Key Identifying Features:

• Spindle: Espag window handles have a square spindle (typically 7mm) protruding from the bottom of the handle, which operates the internal locking mechanism in the window.
• Fixing Points: Typically secured to the window sash with two screws positioned in line with the handle lever. The most common fixing centre distance is 43mm between screws.
• Locking Mechanism: These handles operate an "espagnolette" locking mechanism, which runs along the edge of the window frame and secures it at multiple points when the handle is turned. This multi-point locking provides excellent security and weather sealing.
• Handle Positions: Usually has three positions – closed/locked (vertical), tilt/vent (horizontal), and fully open (downward).

Types of Espag Handles:

• Inline Espag Handles: These are non-handed, meaning they can be used on both left and right-opening windows. This is the most common type.
• Cranked Espag Handles: These have an angled or cranked design and are handed (left or right-handed). They're used when you need the handle to sit closer to the window frame.

When to Choose Espag Handles:

If your handle is fixed with two inline screws and turning it engages multiple locking points around the window frame, you likely have an Espag handle. These are found on virtually all modern uPVC windows, as well as many contemporary timber and aluminium windows.

Measuring Espag Handles:

The main measurement you need is the spindle length. Measure from the base of the handle to the tip of the spindle when fully inserted into the handle. Common spindle lengths include 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 43mm, 50mm, and 60mm.

Cockspur Handles: A Step Back in Time

Cockspur handles are an older style commonly found on uPVC windows manufactured before the late 1990s, as well as on timber and aluminium windows. They are identified by a distinctive "spur" or "tongue" that protrudes from the handle. This spur engages with a wedge or keep located on the window frame to secure the window.

Key Identifying Features:

• The Spur: A prominent wedge-shaped projection that extends from the handle body and locks over a cockspur wedge striker plate on the window frame.
• Fixing Points: Usually secured with four screws arranged in a square pattern around the base of the handle (approximately 24mm x 32mm fixing centres).
• Locking Mechanism: The spur hooks over a fixed point on the frame when the handle is closed, creating compression to seal the window tightly.
• Appearance: They have a more traditional look with a visible spur and tend to be more compact than Espag handles.
• Handed Design: Cockspur handles are handed – you need to identify whether you need a left-handed or right-handed handle based on which hand you use to operate it.

Measuring Cockspur Handles:

The critical measurement for cockspur handles is the backset height (also called step height). This is measured from the base of the handle to the underside of the spur. Getting this measurement correct is essential, as it determines how tightly the window seals.

Common backset heights include:

• 7mm
• 9mm
• 11mm
• 13mm
• 17mm
• 21mm
  

You'll also need to determine the hand of your handle. Stand inside looking out at the window. If you use your right hand to open the handle, it's right-handed. If you use your left hand, it's left-handed.

When to Choose Cockspur Handles:

If your handle has a spur that locks over the frame and is fixed with four screws, it's a Cockspur handle. These are typically found on:

• Older uPVC windows (pre-2000)
• Traditional timber windows
• Aluminium windows
• Caravan and mobile home windows

Tilt and Turn Handles: Functionality and Style

Tilt and Turn windows are characterised by their dual opening mechanism, meaning they can tilt inwards from the top for ventilation or fully open inwards like a door. Their handles are designed to control both these functions and are built to withstand the additional weight and stress of larger window sashes.

Key Identifying Features:

• Spindle: Tilt and turn window handles have a square spindle (typically 7mm) protruding from the bottom of the handle, which operates the internal locking mechanism in the window.
• Fixing Points: Typically have a larger, more robust base and are secured with two screws. The fixing centres are usually 43mm apart, similar to Espag handles.
• Operation: The handle usually has four positions:
• Closed/Locked (pointing downwards): Window is fully closed and locked
• Tilt (pointing upwards): Window tilts inwards from the top for ventilation
• Turn (pointing horizontally): Window opens fully inwards like a door
• Some models also have a micro-ventilation position at 45 degrees
• Appearance: They tend to be chunkier and more substantial than standard Espag handles because tilt and turn windows are larger and heavier and require a more robust handle mechanism.
• Heavy-Duty Construction: Built with reinforced components to handle the weight of large window sashes.

When to Choose Tilt and Turn Handles:

If your window handle allows the window to both tilt inwards slightly from the top and fully open inwards like a door, you have a Tilt and Turn handle. These are increasingly popular in modern homes, particularly in:

• New-build properties
• Apartments and flats
• Homes requiring easy window cleaning from the inside
• Properties where external access for cleaning is difficult

Measuring Tilt and Turn Handles:

Like Espag handles, the main measurement needed is the spindle length. Common lengths for tilt and turn handles range from 30mm to 50mm. You should also measure the fixing centre distance (usually 43mm).

Top Tips for Identifying Your Window Handle

1. Take Photos: Before removing your old handle, photograph it from multiple angles, including the fixing points and any visible markings.
2. Check for Brand Markings: Many handles have manufacturer marks or model numbers that can help with identification.
3. Count the Screws: The number of fixing screws is often the quickest way to distinguish between handle types.
4. Test the Operation: See how many positions your handle has and what movements it enables.
5. Measure Before Ordering: Don't guess measurements – always measure accurately to avoid ordering the wrong size.
6. Look for Multiple of the Same Type: If you have several windows in your home, they'll likely all use the same handle type, making identification easier.
