What to expect from a window quote
A window quote should tell you exactly what you are buying, who is fitting it and how you pay for it. This overview walks through window quote expectations from top to bottom, so nothing on the page takes you by surprise.
What a good window quote actually contains
Every reputable installer builds a quote from the same handful of parts. Once you recognise them, you can read any document quickly and compare two firms fairly. A complete quote should set out the number and style of windows, the exact specification of frames and glass, the labour involved in removing the old units and fitting the new ones, the guarantee, and the payment terms. If any of those sections is missing or vague, that is your first prompt to ask a question.
Prices given over the phone or scribbled on the back of a brochure are estimates, not quotes. A genuine quote follows a home survey where each opening is measured and the condition of the reveals is checked. That is why two firms can look at the same house and price it differently — they may be specifying different products or including different amounts of making good.

The main sections, explained
Start with the breakdown of what is included in a window quote — supply, fitting, making good and waste removal — because that is where hidden extras usually hide. Next comes the specification, which is the technical heart of the price. To read it confidently you will want to understand the jargon that appears on a window quote, from low-E coatings to spacer bars.
The numbers that most affect comfort and running costs are the energy figures. Our guide to U-values and window energy ratings explains why a lower U-value is better and how the A++ to E rating bands compare. From there, the glass options on your quote and the choice of frame materials and finishes determine both how the windows look and how they perform.
Finally, protect yourself on the commercial side. Read the detail of guarantees and what they cover, understand typical deposits and payment terms, learn why window quotes vary so much, and finish with the signs of a fair window quote.
What to check before you compare
When you line two quotes up side by side, make sure they describe the same thing. Confirm the frame material, the glass specification, the number of opening sections and whether trickle vents, cills and making good are included. A cheaper price for a thinner specification is not really cheaper. If you are weighing up materials on a budget, it helps to read up on which window materials give the best value before you decide.
It is also worth checking the firm itself, not just the paperwork. Accreditations such as FENSA or CERTASS registration, TrustMark membership, insurance-backed guarantees and deposit protection are all reassurance that the work will be done properly and covered if anything goes wrong. Taking a few minutes on vetting your installer before you commit is time well spent.
