What Affects the Cost?

UPVC window costs in Slough depend on window size (small casements cost less than bay windows), glazing type (standard double glazing vs. triple glazing or acoustic glass), frame colour and style, ease of access, and whether old frames require removal and making good. Properties requiring scaffold access, structural repairs, or installation of unusual sizes cost more. Material quality, warranty length, and whether the installer handles all certification and building regulation sign-off also influence final pricing.

Money-Saving Tips

Get quotes from 2–3 local installers to compare pricing. Installing multiple windows in one project often reduces cost-per-window. Consider standard white frames rather than coloured or woodgrain finishes. Ask whether the quote includes frame removal and disposal, as this can add £300–500 to your total cost.

Frequently Asked Questions

Why do UPVC window prices vary so much between installers in Slough?

Prices depend on material sourcing, labour availability, warranty terms, and whether the installer includes scaffolding, building regulation approval, and old frame disposal. More established companies with better warranties may charge 10–15% more but often provide superior aftercare and guarantees.

Is it cheaper to replace all windows at once or gradually?

Bulk replacement usually costs 10–15% less per window because installers save on travel time, setup, and project management. A full-house replacement (6–8 windows) in one project typically costs £2,800–£5,500, whereas staggered jobs incur repeated call-out charges.

Does the cost include building regulation approval and guarantees?

Some installers include building regulation sign-off and 10-year UPVC guarantees in their quote; others charge extra. Always confirm what's included in your quote. Expect an additional £150–£250 for building control approval if it's not included.

How long does installation typically take and will my home be secure?

A single window takes 1–2 hours; a full house (6–8 windows) takes 2–4 days. Professional installers remove and fit one window at a time to maintain security, or install temporary board-ups. Emergency glass repairs are available if damage occurs during work.
