Compare uPVC Bay Window Quotes in Winchester

Replacing a bay involves its angles, joints and support as well as the glass. For a bay in Winchester, the survey needs to establish what rests above the frames.

Tell us about the bay you want replaced and Hampshire Windows can pass it to independent installers covering Winchester, Hampshire. Up to four installers may come back to you with a price, subject to their workload, and you pay nothing to ask or to decline.

The Structure Behind Your Bay

On many older houses the original timber bay frame carries part of the weight of a small tiled or lead roof, or even the wall of a bay above. A uPVC frame is not designed to take that load alone. Before quoting, an installer should work out how the weight above is carried, then specify bay poles or structural couplers at the corners to transfer it safely down to the base.

Mention whether there is a roof or another bay above. A photo of the whole bay from the street helps with the first conversation.

Signs Your Winchester Bay Needs Attention

• A sagging bay roof or cracks in the brickwork at the corners of the bay
• Soft or rotten timber where the facets meet the bottom rail
• Water getting in at the joints between the facets
• A cold, damp bay seat or window board in winter
• An old uPVC bay that has bowed, so the sashes rub or will not lock

Bay roof repairs are often easiest to do while the frames are being replaced, which may involve a roofer as well as the window installer.

Getting the Specification Right in Winchester

Ask how the original bay angles will be recorded and reproduced. A projecting bow fitted in a formerly flat opening may need different support and permission from an existing canted bay.

The Replacement Process

1. The survey: each facet and angle is measured, and the installer checks the base and the load above.
2. Specification: frames, couplers and bay poles are specified, and you confirm layout, colour and glass.
3. Temporary support: where needed, temporary support is installed before the old bay is removed.
4. Building the new bay: new frames go in facet by facet, joined with couplers, and the poles are set to take the load.
5. Finishing: the cill, bay board and trims are fitted, sashes adjusted, and props and old frames removed.

Where loads are present, temporary support must be planned before frames are disturbed. The survey may lead to an engineer’s assessment. Bay poles and couplers must transfer loads to an adequate base, and roof flashing defects need their own repair allowance.

Tell firms whether delivery and any access tower would occupy space outside your Winchester boundary. Agree whether the bay board will be replaced or retained.

What Does a New Bay Cost?

The guide range for this service is £1,800–£6,000. A standard three-facet ground-floor bay in white usually sits near the bottom of that range, while larger assemblies cost more; multiple bays, lintels and roof repairs can exceed it. Only a survey can turn this into a real figure for your house.

Ask whether the quote includes scaffolding, bay poles, a new cill and bay board, bay roof repairs, VAT and making good inside. These items are sometimes priced separately and can make a big difference to the total.

Checking Permissions

Replacing an existing bay with one of similar size and shape is normally treated as a like-for-like replacement. Building a new bay where there was a flat window, or changing its shape, alters the front of the house and is more likely to need planning permission. Check with Winchester City Council if you are changing the design, if the house is listed, or if it is in a conservation area.

The new bay must meet the Building Regulations like any other window, and a competent person scheme installer can usually self-certify it. Structural work beyond a straightforward replacement, such as a new lintel or rebuilt base, may need building control approval. The Planning Portal's Building Regulations guidance has more detail.

Get Started

Start with your postcode and a few words about the bay. Hampshire Windows introduces enquiries and does not carry out installations. Businesses joining the network are asked for insurance details and references; check current evidence and ask to see similar bay jobs before you choose.

These prices are planning allowances, not fixed quotations. Quantity, specification, access and additional work can take the total outside the range. Describe your project to request free quotes.

For eligible replacement work, confirm the installer’s scheme registration and certification arrangements. An appropriate building control approval route is another option; see the government guidance on competent person schemes. If the address lies within a national park, confirm which planning authority handles the property before ordering.
