Brighton & Hove: replacement aluminium windows
The price of aluminium windows depends on the size and number of frames, the profile system, opening sashes, colour and finish, glass specification and access. Dual colours, special finishes, glazing bars and triple glazing add cost. See the guide prices for typical ranges, and the written quote fixes your figure.
Modern aluminium window frames contain a thermal break: strips of low-conductivity material, usually polyamide, that separate the inner and outer aluminium. Without it, heat passes straight through the metal. Older aluminium windows made without thermal breaks are a common cause of cold frames and streaming condensation.
Security on aluminium windows comes from multi-point locking, internally glazed beads, lockable handles and robust hinges. For easily accessible windows in new homes in England, Approved Document Q expects security to the PAS 24 standard, and specifying the same for ground-floor replacements is a sensible precaution.
Aluminium is strong enough to hold large, heavy glass units in narrow frames, so sightlines are slimmer than uPVC of the same size. That means more glass and more daylight from the same opening, which suits modern extensions, wide picture windows and slim replacements for old steel windows.
What a typical job includes
- Written guarantee terms and advice on building regulations sign-off
- Fitting, sealing and finishing the reveals neatly

- Coast
- Brighton & Hove is about 1 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. Salt air attacks metal finishes, so aluminium windows near the coast need a coating and pretreatment suited to marine exposure, stainless or protected hardware, and more frequent washing. Check that the coating terms allow for a coastal site before ordering.
- Daylight and sun
- In Brighton & Hove the midwinter sun reaches about 16° above the horizon at noon, with roughly 7.7 hours of daylight, rising to about 63° and 16.3 hours in midsummer. Slim aluminium frames let more daylight through the same opening. Large south or west-facing panes can overheat rooms, so solar-control glass may help, while north-facing rooms benefit from high light-transmission low-E glass that keeps heat in during short winter days.
- Access and setting
- Large aluminium units are heavy, so city jobs need planned unloading, parking and sometimes lifting gear or extra hands for upper floors. Flats need freeholder consent and planning permission, and conservation areas often control frame colour and glazing bar patterns.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.
Choosing your aluminium windows
Glass upgrades
Triple glazing, laminated acoustic glass, solar-control coatings or obscure glass, chosen per window to suit the room and elevation.
Flush casement
Sashes sit level with the outer frame for a clean, timber-like look, often chosen for period-style or contemporary homes.
Tilt and turn
Inward-opening sashes that tilt for secure ventilation or swing open for cleaning and escape, useful for flats and high floors.
Aluminium Windows in Brighton & Hove: questions
What guarantee do aluminium windows come with?
Manufacturer guarantees apply to the frames, powder coating, hardware and sealed units, and the terms are confirmed in writing. Coating cover often depends on the site environment and on regular cleaning, so read the conditions. Guarantee terms for the installation are set out in writing with your quote, before you agree to go ahead.
How long does it take to install aluminium windows?
Most single windows are fitted within a day, and a typical house takes a few days on site depending on the number of windows and the access. The longer part is manufacturing, because frames are cut, coated and glazed to the survey sizes. The expected lead time is confirmed in writing when you accept the quote.
Can aluminium windows replace original steel windows?
Yes, steel-look aluminium windows are designed for this. They copy the slim frames and glazing bars of old metal windows while adding double glazing and a thermal break. Original steel frames are often set into the masonry, so removal can disturb render or plaster, and the survey checks this. Listed buildings and conservation areas may need consent first.
Are aluminium windows better than uPVC?
Neither is better for every home; they suit different priorities. Aluminium gives slimmer frames, larger glass areas, a hard-wearing powder-coated finish and a wide colour choice. uPVC usually costs less and has chunkier frames. Both can meet the energy standard for replacement windows when specified correctly, so compare the certified ratings, the look you want and the guide prices.
