Bay window replacements in Preston Park, Hanover and Hove
Brighton’s Victorian terraced streets in Preston Park, Fiveways and Hanover are wall-to-wall with bay-fronted stock, and Hove’s Edwardian bays face straight into the salt-laden sea breeze. Legacy Windows connects homeowners with three bay specialists who quote a fixed price for a square, splayed or canted replacement, including the structural head detail where the bay is load-bearing.
Why locals in Brighton choose Legacy Windows
- Typical 2026 pricing sits between £1,760 for a compact three-light UPVC square bay and £4,180 for a splayed aluminium or timber replacement, adjusted for Brighton trade rates.
- All matched installers are FENSA or CERTASS registered, and any load-bearing bay head is covered by a separate Building Regulations sign-off with structural calculations.
- Marine-grade stainless steel fittings and thicker seals are specified as standard, since exposed bays in BN3 and Rottingdean weather harder than any other window in the house.
- Every unit hits a whole-window Uw of 1.4 W/m2K or lower under Part L 2022, with self-cleaning coatings offered on south-facing seafront bays.
- Timber and heritage aluminium options are itemised for conservation streets where UPVC would be refused.
Areas we cover around Brighton
Bay window briefs are heaviest in BN1 across Preston Park and Fiveways, BN2 across Hanover and Bevendean, and BN3 across Hove, Aldrington and Poets Corner. Rottingdean and Ovingdean generate a steady flow of Regency and interwar bay briefs. Any address inside one of the thirty-four conservation areas is flagged so we can steer specification to timber or slim aluminium where UPVC is not permitted.
Frequently asked questions
Is Building Regulations sign-off needed for a bay replacement in Brighton? Yes if the bay carries the wall above, which is common on Preston Park and Hanover Victorian terraces. A lintel, structural calculation and separate building notice are required in addition to the FENSA glazing certificate.
Can I fit UPVC on a bay-fronted Regency terrace? Usually no. Kemptown, Brunswick and Montpelier require timber or a slim heritage aluminium equivalent on street elevations. Our panel quotes both options where you sit on a conservation street.
How does salt exposure affect a Hove seafront bay? Frame gaskets and hinges take the brunt. Marine-grade stainless steel and thicker EPDM gaskets extend the service life. Every quote on our BN3 panel includes them.
