Choosing a window fitter in Bath requires a bit more thought than in most towns. Bath is a UNESCO World Heritage Site, and large parts of the city fall within a conservation area. This means that replacing windows is not simply a matter of picking the cheapest double glazing company. Depending on where your property sits, you may need to match specific styles, materials, and even glazing bar patterns to comply with planning requirements.
If your property is in one of Bath's conservation areas, which covers most of the Georgian city centre and extends into areas like Lansdown, Widcombe, and Bathwick, you will almost certainly need to use timber windows or high-quality timber-effect alternatives. Standard white uPVC windows are generally not acceptable in these locations. Bath and North East Somerset Council (BANES) takes these rules seriously, and fitting non-compliant windows can result in enforcement action requiring you to replace them at your own cost.
For properties outside conservation areas, you have more flexibility. Modern uPVC windows offer good thermal performance and low maintenance, while aluminium frames give a sleek contemporary look. Timber remains popular with homeowners who value traditional aesthetics and are willing to maintain them. Composite windows, which combine a timber interior with an aluminium or uPVC exterior, offer a middle ground.
Costs for window replacement in Bath vary depending on the material and property type. Standard uPVC double-glazed windows cost between £300 and £600 per window including fitting. Timber sash windows, which many Bath properties require, are significantly more expensive at £800 to £2,000 per window depending on size, timber species, and the complexity of the design. Aluminium windows typically fall between £500 and £1,200 per window. For a full house of windows on a typical three-bedroom Bath property, budget between £3,000 and £8,000 for uPVC or £8,000 to £20,000 for timber sash replacements.
When looking for a window fitter in Bath, check that they are registered with FENSA or CERTASS. These are competent person schemes that allow window installers to self-certify that their work complies with Building Regulations. If your fitter is not registered with one of these schemes, you will need to arrange a separate Building Control inspection, which adds cost and hassle.
Energy efficiency is increasingly important, and current Building Regulations require replacement windows to meet minimum thermal performance standards. Look for windows with a Window Energy Rating of at least C, though A-rated or A+ rated windows will save you more on heating bills. In a city like Bath, where many properties have solid stone walls with limited insulation options, upgrading windows can make a noticeable difference to comfort and energy costs.
For listed buildings in Bath, and there are many, you will need Listed Building Consent before replacing any windows. This is a separate process from planning permission and involves demonstrating that the replacement windows will preserve the character of the building. Specialist heritage window companies operating in Bath understand this process and can help with applications. In some cases, refurbishing existing windows rather than replacing them may be the preferred approach.
Getting quotes from Bath window fitters is straightforward. Most will offer a free survey and quotation, visiting your property to measure up and discuss your options. Aim for three quotes as a minimum, and make sure each quote specifies the window material, glazing specification, ironmongery, and any making good included.
If you run a window fitting business in Bath, professional documentation helps you stand out. Use a free quote generator at invoiceadept.com to create detailed estimates for customers, and follow up with professional invoices once the job is complete. Clear, well-presented paperwork builds confidence, especially for the higher-value heritage window projects common in Bath.
Consider the installation timeline carefully. Removing old windows leaves openings in your home, so you want a fitter who can complete the work efficiently. Most standard window replacements take one to two days for a full house, but heritage sash window installations can take considerably longer. Discuss the timeline and any temporary weatherproofing arrangements before work begins.
Sound insulation is another factor worth considering in Bath, particularly for properties on busy roads like the A4 through the city or near the railway line. Acoustic glazing options can significantly reduce noise transmission and are worth discussing with your window fitter if traffic noise is an issue.

Frequently Asked Questions
Do I need planning permission to replace windows in Bath?
If your property is in a conservation area, which covers much of central Bath, you may need planning permission, particularly if you want to change the style or material of the windows. Listed buildings always require Listed Building Consent. Properties outside conservation areas can usually replace windows under permitted development rights, provided they match the existing appearance.
How much do new windows cost in Bath?
Standard uPVC windows cost £300 to £600 per window fitted. Timber sash windows, common in Bath conservation areas, range from £800 to £2,000 each. A full set of windows for a three-bedroom house typically costs £3,000 to £8,000 for uPVC or £8,000 to £20,000 for timber sash replacements.
Can I use uPVC windows in Bath?
In many parts of central Bath and its conservation areas, standard uPVC windows are not permitted. You will generally need timber or approved timber-effect alternatives. Outside conservation areas, uPVC is usually acceptable. Check with BANES planning department or ask your window fitter about your specific property.
What is FENSA and why does it matter?
FENSA is a competent person scheme that allows registered window installers to self-certify compliance with Building Regulations. Using a FENSA-registered fitter means you automatically get a certificate confirming the work meets regulations, which you will need when selling your property. Without FENSA, you need a separate Building Control inspection.
How long does window replacement take?
A full house of standard windows can usually be replaced in one to two days. Heritage timber sash window installations in Bath properties typically take longer, sometimes a week or more for a full house. Your fitter should provide a clear timeline before work begins.
