uPVC windows fitted price vs buying windows only

uPVC windows fitted price or windows only with your own fitter? A comparison table, when each makes sense and how to work out both for your home.

uPVC windows fitted price: when you buy from a local company, one figure covers the product, survey, removal of the old windows, installation and finishing, and one company is responsible for the result. That single figure also includes the installer's margin on the windows themselves, which makes it hard to break down. Buying the windows on their own and paying a fitter separately gives you two clear bills and usually a lower product cost, but the measuring and coordination are down to you.

The short verdict: go for a fitted package if you have no installer or a grant requires installation by a company. Buy the windows alone if you have a trusted fitter and are ordering several windows at once.

uPVC windows fitted price: what the package includes

A fitted quote usually bundles several items: windows and extras, survey, removal and disposal of old frames, installation, making good the reveals, sills and fitting materials. The company also adds travel and its own markup on windows bought from the manufacturer. There's nothing wrong with that, but with one figure you can't see what the window costs and what the labour costs.

For years we made, installed and exported windows ourselves. Today we sell only the product: made-to-measure uPVC and aluminium windows and doors, online. We don't offer installation and don't recommend particular fitters, because we take no commission from them.

Side-by-side comparison

| Criterion | Fitted package | Windows only + your own fitter | |---|---|---| | Price | one figure, hard to break down | product and labour separate, easy to compare | | Survey | done by the company, which is responsible for sizes | you or your fitter measure | | Responsibility | one company for window and fitting | seller for the window, fitter for the installation | | Choice of systems | whatever the company stocks | with us 15 uPVC and 4 aluminium systems, each priced instantly | | Timing | set by the company | production 3–8 weeks plus your fitter's schedule | | Grants | conditions easier to meet | check the scheme's conditions before buying | | Unloading | usually the company | you: forklift or 2–3 people |

When the fitted package makes more sense

  • You have no installer and don't want to coordinate dates.
  • You're counting on a grant. Support schemes have their own conditions and often require installation by a company, so check them on the scheme's official website or with an adviser first.
  • You're replacing a single window. We recommend at least 2 windows or one lift and slide door, because with a smaller order transport eats the saving.
  • You want one point of contact for every complaint, whether the problem is the window or the fitting.

When to buy the windows alone and hire a fitter

  • You have a reliable builder, or you're building a house with a team that installs windows anyway.
  • You're ordering windows for the whole house. Transport is charged per rack space, so its share of the total drops as the order grows.
  • You want a specific system, colour or glazing and want to see what each change costs straight away.
  • You're building abroad. We've exported windows to Germany, the Netherlands and Switzerland since the late 1990s and deliver regularly to Belgium, France, Austria and the Czech Republic too.

Windows only means you supply the sizes. From more than 5,000 orders we know where mistakes happen most: the opening size given as the frame size, the opening side described from outside, a top-mounted roller shutter added after measuring even though the box adds to the window's height. With every quote we check sizes, opening sides and descriptions, and before production we send a drawing and specification for approval.

How to compare both options with your own numbers

1. Build your windows in the window configurator. You see the price straight away after every change and can price the same project in several systems. 2. Ask a local fitter for a labour-only quote that lists removal and disposal of old windows, installation, materials, making good, sills and unloading. 3. Add the transport from our quote. A person prepares it within 3 working days, with the transport amount shown before you order. 4. Compare the total with a fitted quote for the same specification: same system, glazing, colour, layout and extras.

What drives the price of the window itself is explained in how much windows cost without fitting, and how to read the figures in quotes in our article on the declaration of performance. The ordering process step by step is on how it works.
