How we rank

Our verdicts are earned, not bought

Every rating on this site comes from the same set of criteria, applied the same way to each option. Here's what we weigh.

  • Thermal performance

    We compare whole-window U-values and energy ratings, not headline glass figures.

  • Security

    We treat PAS 24 and multi-point locking as a baseline to expect, not a bonus.

  • Durability & lifespan

    Typical service life, weathering and how a frame ages in a real UK home.

  • Value over time

    Beyond the sticker price: upkeep, repairs and how long a window keeps performing.

  • Aftercare & guarantees

    Warranty length, installer accreditation and what happens if something goes wrong.

Good to know

Questions people ask us

How do you decide which windows are “best”?

Every option is scored against the same criteria — thermal performance, security, durability, value over time and aftercare — using published U-values, product specifications and recognised standards such as PAS 24. Superlatives on this site are always “best for X”, tied to those criteria rather than to how much a brand advertises.

Does it cost anything to compare or get quotes?

Comparing on this site costs nothing, and quotes from your matched installer are free with no obligation. Funding and contribution options may be available, subject to eligibility and a home survey, and £0-upfront options may be available for those who qualify.

Do I need to own my home?

Our comparisons and quotes are aimed at UK homeowners and owner-occupiers. Renters can still enquire, but an installer will need the homeowner's go-ahead before any work is agreed.

Who actually contacts me after I enquire?

A matched, top-rated installation partner will call you by phone about your enquiry — for us that's Help 2 Buy Windows. We only pass on the details you provide so they can prepare your quote.

Is “No.1 on Trustpilot” your own claim?

No — it's attributed to our installation partner, Help 2 Buy Windows, which is rated 4.9/5 “Excellent” on Trustpilot from more than 12,000 reviews. You can read the reviews on Trustpilot yourself.
