Find double glazing installers in Gerrards Cross

Looking to cut energy bills, reduce outside noise, and improve your home’s comfort?

Double glazing installation offers a durable and energy-efficient solution.

At Checkatrade, you can connect with checked double glazing installers near you, each reviewed by real customers, so you can hire with confidence.

How much does double glazing cost in the UK?

There are several factors that affect the cost of double glazing, including the size and type of windows you choose, the frame material, and installation complexity.

On average, expect to pay around:

  • £500–£1,250 per uPVC casement window
  • £700–£1,500 per sash window
  • £600 - £1,400 per sliding window
  • £600 - £1,400 per tilt and turn window
  • £1,100 - £4,000 per bay window
  • £1,500 - £5,000+ per bow window

The average cost of adding double glazing to a three-bedroom house, based on roughly 8-12 windows, is around £8,000–£15,000.

Our double-glazing cost guide has more detailed information.

What are the benefits of double glazing?

Installing double glazing comes with a range of advantages:

  • Energy efficiency: reduces heat loss and lowers energy bills
  • Noise reduction: keeps outside noise to a minimum
  • Security: modern glazing includes toughened glass and multi-point locks
  • Increased property value: an attractive selling point for buyers
  • Low maintenance: especially with uPVC frames

How long does double glazing installation take?

The installation process depends on the number of windows:

  • For straightforward fittings, 1–2 hours per window
  • For an entire house, 1–3 days

Installers will remove the old units, prepare the frames, and fit the new double-glazed windows, ensuring minimal disruption to your home.

Do I need planning permission for double glazing?

In most cases, you won’t need planning permission for double glazing, especially for like-for-like replacements.

Permission may be required if:

  • Your property is in a listed building or conservation area
  • You are significantly altering the external appearance

A checked installer in Gerrards Cross can let you know if additional approval is needed.

Tips for hiring double-glazing installers in your area

Before booking double glazing installation near you, follow these steps to help ensure the right choice of hire:

  • Read customer reviews on Checkatrade
  • Check to ensure they offer the services you need — for example, replacing misted units or full-house installations
  • Ask for a detailed quote that includes materials, labour, VAT, and disposal of old windows
  • Confirm if they provide guarantees on both the glass units and installation work
  • Compare several quotes to find the right service

For tradespeople committed to quality and a job done right, search for double glazing installers in your area with Checkatrade.
