Double Glazing Cost in East Grinstead: 2026 Price Guide

/in /by

Double glazing cost is the first question most homeowners ask us. It is a fair one. New windows are a big spend, so you want real numbers before you pick up the phone. This guide shows typical UK prices for 2026. It also explains what moves your quote up or down.

What is the average double glazing cost per window?

For standard uPVC windows, most UK homeowners pay roughly £160 to £250 per window, fitted. That figure suits a typical casement of around 600mm by 900mm. However, size and style change it quickly. Small windows can cost closer to £100. Large windows often reach £300 or more. Sash and bay windows cost more again, and premium frames can pass £1,000 each.

Prices in London and the South East are often higher than the national average. So treat these figures as a guide, not a quote.

How much does a whole house cost to double glaze?

Whole-house prices depend on how many windows you have. A national guide puts the materials for a ten-window house at around £3,000. A three-bed semi with 10 to 15 windows typically costs £4,000 to £7,000 fitted in uPVC. Premium options can push that to £10,000 or more.

For a quick comparison, here are typical material costs:

  • Flat with four windows: about £1,300
  • House with eight windows: about £2,500
  • House with fifteen windows: about £4,500

Remember that fitting is extra. Labour usually costs £200 to £280 a day for a fitter.

What changes your double glazing cost?

Several things move the price. Knowing them helps you compare quotes fairly.

  • Frame material: uPVC is usually the cheapest. Aluminium and timber cost more.
  • Window style: casements are simple. Sash, bay and bow windows need more materials and labour.
  • Glass type: Low-E, toughened or laminated glass adds to the bill.
  • Size: larger windows cost more to make and fit.
  • Extras: coloured frames and special handles add cost.

Also set aside another 10 to 15% for surprises. For example, a fitter may find a damaged sill or crumbling plaster once the old window is out.

Is double glazing worth the cost?

For most homes, yes. Modern windows keep heat in, so your heating works less. They also cut draughts and street noise. In addition, uPVC frames need very little upkeep. A good set of windows commonly lasts for decades, so the double glazing cost spreads over a long time.
