What homeowners ask window installers

With what our guides tell them. Answer these in your quote, and later on your listing.

Will I get a certificate for the new windows?

A registered installer signs off replacement windows and doors themselves and gives you a certificate that they meet building regulations. Without it you’d need to apply to building control yourself. Homeowners look for a FENSA or Certass certificate, so add your scheme as a badge.

How many windows have you priced, and which opening types?

The number, sizes and opening types come first on the checklist homeowners use, then frame material, glazing and colour.

Is the guarantee insurance backed?

Homeowners are told to ask the length of the guarantee and whether it is insurance backed. Glass and Glazing Federation membership shows as a badge once checked.

What homeowners will ask you to confirm

From the checklist in our replacement windows guide:

Count: Number, sizes and opening types.
Product: Frame material, glazing and colour.
Certification: FENSA or Certass certificate.
Guarantee: Length and insurance backing.

What we’ll check before window installers appear

Companies House, if you’re a limited company or LLP: we’ll check the company is active.
Only if you take waste away: Waste carrier registration. The law and the registers
Who runs the business: an ID check, or a code letter for a company’s director.

Badges you can add (not needed to appear): Windows and doors competent person scheme, Glass and Glazing Federation and TrustMark, and insurance.

Your listing will say, for example: Checked by Estiquote on 30 October 2026:

If you’re a limited company

Active company at Companies House

Limited company · VAT registered

If you’re a sole trader

Sole trader: business details checked by Estiquote

Sole trader · Not VAT registered

When sign-up opens for window installers, have ready your company number if you’re a limited company, your waste carrier registration number if you take waste away. Then you’ll create your account and send your profile for checks; we’ll usually reply within 5 working days.

Homeowners will choose up to 3 firms by name, and reviews will come only from real jobs, checked by a person: how quote requests and reviews will work.
