uPVC bay windows that open up a room

Why a bay window changes how a room feels

A flat window lets light in from one direction. A bay catches it from the front and both sides, so a lounge that felt gloomy by mid-afternoon stays brighter for longer. Because the frame sits proud of the wall, you also gain a little floor space and a wider view up and down the street.

Many 1930s and post-war homes were built with bays, and the original timber ones are often the first windows to rot, sag or let in draughts. Replacing them with uPVC keeps the shape of the house while ending the cycle of filling and painting.

Because a bay has so much glass, it is often where the room loses most of its warmth. A new double glazed uPVC bay seals tightly into the opening and keeps that heat in the lounge. Curious how your whole home rates? Put your postcode into our free energy check.

Choose your shape, from two sides to eight

No two bays are quite the same, which is why every one we fit is made to measure. You can choose from two-sided designs up to eight-sided bays, depending on the shape of the opening and the look you want.

Each bay is built from individual window sections, so you can decide which ones open and how. Many people pick casement openers on the side panes and a fixed or opening centre, which gives good airflow and a clear view out.

Colours and finishes for bay windows

Bays are a large feature on the front of a house, so the colour matters. Standard white is still the most popular choice, but we also fit bays in grey, oak, cream and other finishes.

If you are changing other windows at the same time, we can match the whole house so the front looks consistent. Try colours on a photo of your own home with our free online designer first.

Is a bay window right for your room?

A bay works best in rooms where you spend time and want more daylight, such as a front lounge, a dining room or a main bedroom. It also suits houses that were built with a bay and have lost their charm through tired or mismatched windows.

If you are adding a bay where there was a flat window before, there is more building work involved, and planning rules may apply. Our surveyor will tell you which applies to your home at the free visit.

Fitted by people who know bays

Bays are more involved than a standard window. The sections have to be joined accurately and the roof or head above has to be sealed properly, or water finds its way in. That is why our own fitters do every bay we sell.

Our own trained installers fit every bay, and it is covered by our 10-year guarantee on uPVC windows. We fit bays from all seven of our branches.
