Simon and Brandon fitted our three windows in our garage > studio conversion and were great through the day. Arrived when they said they would, were very polite, respectful and pleasant people. Found answers to questions we didn’t realise about the installation and though we haven’t yet finished the project the windows are a very exciting and big step forward for us. Would recommend this company and this team without hesitation. Thank you!

Bowalker replaced all of our windows and patio doors in November. They are very efficient and got the job done in the pouring rain but did it quick and professionally. We had a couple of teething issues with the doors after completion and they did not hesitate to come out and rectify the issue. Excellent customer service and a friendly team. Would highly recommend

We had a total of 6 windows fitted at end of June 2025 (2 bathroom(frosted), 1 hallway,1 dining room and two big bay windows complete with 2 window boards). Took 5 days in total as bay windows were load bearing ,the window boards were not in warehouse so took extra time to arrive and fit , the silicone/mastic finish wasn’t great and they cut one end of a window board wrong , but after a telephone call a new team of fitters came out and rectified the mistakes of original fitters that we had noticed , a window pane had got scratched in delivery so they replaced that as well. This was a big job that entailed some mistakes but over time was rectified by bowalker windows by sending out another team of fitters to fix some minor mistakes of original fitters . We went on a recommendation from a work colleague who had used Bowalker windows in the past as were very good. Maybe just improve your fitters mastic silicone skills a bit more but is is an old house of 110 years and nothing is level in this house

Frequently Asked Questions

Bay windows are windows that project outwards from the external wall of a property, creating additional interior space and allowing natural light to enter from multiple angles. They typically consist of a larger central window with two or more side windows set at an angle or gentle curve. Bay windows are available in designs such as box bays, bow bays, splay bays and single-end bays, making them suitable for both period and contemporary homes.

The total cost of a fully fitted bay window in the UK typically ranges from £1,500 to £4,500, with most homeowners paying around £2,000 to £3,000 for a standard three-panel uPVC double-glazed bay. At Bowalker, our installation rate starts from £450 for bay windows under 5m², rising to £900 for larger bays over 5m². The final cost varies depending on frame material, with uPVC being the most affordable and aluminium and timber commanding a higher price, alongside window size, glazing specification and whether any structural adjustments are required.

Most bay window installations are completed within 1 to 2 days, although larger bays or projects requiring structural work may take longer. Before installation begins, our team carries out a detailed survey to confirm measurements, assess the existing opening and plan the installation process. Our in-house installers complete every installation carefully to minimise disruption whilst ensuring the new bay window is securely fitted and fully compliant with current Building Regulations.

Clean bay windows by washing frames with warm soapy water and a soft cloth, avoiding abrasive cleaners that can damage painted, powder-coated or woodgrain finishes, before cleaning the glass with a non-abrasive glass cleaner to remove smears and residue. Clean opening sashes, hinge mechanisms, multipoint locking hardware and drainage channels regularly to prevent debris accumulation, maintain smooth operation and ensure weather seals remain effective throughout the year.

The right bay windows depend on your property’s architectural style, available space, energy-efficiency requirements and preferred frame material. Traditional homes often suit engineered timber or heritage-style uPVC bay windows, whilst aluminium bay windows complement contemporary properties with their slim sightlines and larger glazed areas. During your consultation, we assess your property and recommend bay windows that combine appearance, performance and practicality.

The best bay window design complements your property’s architecture whilst improving natural light and usable living space. Features such as double or triple glazing, decorative glazing bars, leaded or stained glass and integrated window seats can all enhance the finished appearance. Choosing frame colours and finishes that match your existing windows and doors also creates a balanced and consistent exterior.
