Step 2: Tender Presentation
Get up to Ten Quotes from One Visit

Your Window Advice Centre approved consultant will go over your tender report to ensure that everything is to your complete satisfaction before anything moves forward.


Approximately one week after your initial survey, your Consultant will return to you with your tender report.


Your tender report will consist of a copy of the tender document, a list of the double glazing contractors and their itemised costs. Your report will also include background information on the double glazing contractors and copies of their literature showing the replacement window and doors they use.

Up to ten approved double glazing contractors will have been given one chance to submit their lowest possible cost to undertake the work set out in your tender document. As each contractor knows that up to another nine contractors are competing for your work, you can be confident of getting the keenest possible price.

As all contractors are quoting to undertake the work on a like for like basis, you are able to consider the least expensive quotation knowing that you are not sacrificing anything in quality.

This resolves the problem that consumers face of trying to identify from a range of offers, for replacement windows and doors of similar appearance but varying quality, which offer represents the best value for money.


Your Consultant will go over your tender report to ensure that everything is to your complete satisfaction. You can alter the proposals for your replacement window and doors and obtain revised costs as many times as you wish until you are completely satisfied that the proposals for your replacement windows and doors are exactly in line with your wishes.

You are under no obligation to accept any of the offers. However, as all the quotes are to the same specification, most people will accept the lowest quote received.


When you accept a contractor’s offer through Window Advice Centre, every aspect of the work that the contractor is obliged to provide under the contract is documented in detail. This provides the point of reference for your consultant to inspect your installation on completion to ensure that it is as specified and to the required standard BEFORE you pay.


You are also protected by the Window Advice Centre Code of Practice for Approved Contractors. This Code of Practice defines the detailed technical standards for the quality of the replacement windows and double glazing to be used and the standards that your installation must meet before your selected contractor is due final payment.

The Code is written to include conditions that protect your interests where the contractor’s normal Terms and Conditions would concentrate on protecting the contractor.

Window Advice Centre Approved Contractors

Window Advice Centre holds a Register of Approved replacement window and double glazing Contractors.

Any replacement window or double glazing contractor is free to apply to Window Advice Centre for assessment.

Contractors must provide evidence to show that they are financially stable, have a minimum of two years trading and are able to provide Certification from independent testing laboratories, such as the Building Research Establishment (BRE), to show that the materials they use in their replacement windows, doors and double glazing meet or exceed the requirements of the British Standards.

To ensure the double glazing contractors are capable of meeting the service standards set out in the Window Advice Centre Code of Practice, a number of their replacement window and door installations are inspected and references obtained from previous clients.
