uPVC window installation in London

uPVC window installation is one of the most cost-effective ways to improve your home’s energy efficiency, security, and appearance.

Whether you’re replacing old timber windows or fitting new ones, search for checked uPVC window installation in London with Checkatrade for a commitment to quality and a job done right.

UPVC windows: An overview

uPVC (unplasticised polyvinyl chloride) windows are durable, low-maintenance, and highly energy-efficient.

Installation involves:

  • Removing your old frames
  • Preparing the openings
  • Fitting new double- or triple-glazed units sealed to prevent drafts and moisture

They’re a popular choice for homeowners across the UK thanks to their insulation, security, and weather resistance.

How much does uPVC window installation cost?

The average cost of uPVC window installation in the UK varies depending on size, glazing type, and frame style. Use these average prices as a guide:

  • Casement window: £300–£500
  • Sash window: £500–£800
  • Tilt and turn windows: £500–£800
  • Bay windows: £1,250–£2,150
  • 3-bed house (12 casement windows): £5,000–£10,000

Calculate the cost of your uPVC window installation using our comprehensive cost guide.

uPVC vs other window materials

Compared to timber or aluminium, uPVC offers the best value for money and requires minimal upkeep.

  • uPVC: Affordable, weatherproof, great insulation
  • Aluminium: Sleek design, more expensive, lower insulation
  • Timber: Natural appearance, high maintenance, costly

If you’re after low maintenance and energy efficiency, uPVC is the ideal all-rounder for modern homes.

How long do uPVC windows last?

uPVC windows typically last 20–35 years with proper maintenance.

High-quality installations can last even longer if cleaned regularly and checked for seal integrity.

Their long lifespan and resistance to rot, rust, and corrosion make them a worthwhile investment.

Maintaining your uPVC windows

Maintaining uPVC windows is simple, just follow these tips:

  • Clean frames and glass every few months using mild detergent
  • Check seals and hinges annually for wear
  • Lubricate locks and handles to keep them moving freely

These small steps will help extend your windows’ lifespan and maintain their energy efficiency.
