Pick the style, size and number of windows and this gives you a realistic supplied-and-fitted range for your region — the same ranges we quote from, not a 'from' price designed to get a salesperson through your door.
The calculator starts from the real supplied-and-fitted band for the style and size you choose, applies the regional index for your area, and adds for glazing upgrades and dual colour where you select them.
It gives you a range, not a single number, because a window quote genuinely is a range until someone has seen the opening. What it will do is tell you within a few hundred pounds whether the quote in your hand is sensible.
Access — whether the job needs scaffolding. Structural work — whether a lintel is failing or a bay needs propping. Making good — how bad the plaster is behind the old frame. Those are survey questions, and they are the reason a fixed price needs a fixed survey.
If the estimate and your quote are wildly apart, that gap is usually one of these three things, and it is worth asking about.
It is an accurate range, not a quote. It uses real supplied-and-fitted price bands adjusted for your region. What it cannot see is access, structural condition and making good — which is why a fixed price needs a survey.
Because a single number would be a guess dressed up as a fact. The range is honest: it tells you what the job costs across the normal variation in spec and site conditions.
