Canterbury: 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.
Large aluminium windows that reach low down, such as floor-to-ceiling glazing, need safety glass. In England, Approved Document K treats glazing within 800mm of the floor as a critical location, so those panes are usually toughened or laminated and permanently marked to show their safety classification.
Powder-coated aluminium does not need painting, but it does need cleaning. Wash frames with warm water and a mild detergent a few times a year, rinse, and avoid abrasive pads or solvents. Clean more often near the sea or busy roads, where salt and grime sit on the surface for longer.
Aluminium windows are fabricated to order: profiles are cut, coated, assembled and glazed to the survey sizes. Lead times can be longer than for standard white uPVC, particularly for special colours or steel-look designs, and the expected timescale is confirmed in writing when you accept the quote.
What a typical job includes
- Written guarantee terms and advice on building regulations sign-off

About Canterbury for this job
- Postcodes covered
- CT1, CT2, CT5, CT6 and the surrounding area, including Whitstable, Herne Bay and Faversham
- Coast
- Canterbury sits roughly 11 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. 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 Canterbury the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 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
- Rural homes often mix old stone walls with modern extensions, and aluminium suits both when profiles are chosen carefully. Irregular openings are measured individually, and exposed sites benefit from systems with high weather ratings and well-sealed joints against driving rain.
- 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.

In England, replacing a whole window, roof window or glazed external door is building work. It has to be notified to building control, either by an installer registered with a competent person scheme such as FENSA or Certass, or through a building notice to the council. Replacing only the glass in an existing frame is a repair and is not notifiable.
Specification choices
Tilt and turn
Inward-opening sashes that tilt for secure ventilation or swing open for cleaning and escape, useful for flats and high floors.
Dual-colour powder coat
A different colour inside and out, such as anthracite grey outside with white inside, from a wide range of RAL colours and textures.
Flush casement
Sashes sit level with the outer frame for a clean, timber-like look, often chosen for period-style or contemporary homes.
Aluminium Windows in Canterbury: questions
What colours can aluminium windows be?
Aluminium windows can be powder coated in almost any RAL colour, in matt, satin, gloss or textured finishes, and many systems offer a different colour on each side. Anthracite grey, black and white are common choices, but heritage greens, creams and bronze tones are available too. Special colours can extend the manufacturing lead time, which is confirmed with the quote.
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.
Do I need permission to replace windows with aluminium?
In England, replacing windows on a house with ones of similar appearance usually does not need planning permission, but changing the material or style can matter. Flats and maisonettes lack permitted development rights for windows, and listed buildings, conservation areas and Article 4 directions can require consent. Building regulations apply to replacement windows across the UK, with different detail in each nation.
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.
