Leicestershire: aluminium windows
In England, a replacement window in an existing home should achieve a U-value of 1.4 W/m²K or better, or a Window Energy Rating of band B, under Approved Document L. Thermally broken aluminium with low-E double glazing can meet this; ask for the certified whole-window figure, not just the glass value.
Aluminium windows can be fitted with trickle vents in the frame head, which matters because in England, Approved Document F expects ventilation after window replacement to be no worse than before. The glazier records the existing vents at survey and sizes new ones to suit each room.
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.
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 applies in Leicestershire
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.
Leicestershire is inland, around 63 km from the nearest coast at its closest point, so salt exposure is rarely a factor.
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.

Choosing your aluminium windows
Casement windows
Side-hung, top-hung or fixed sashes in slim aluminium frames, suiting most houses and extensions, with flush or stepped sash designs.
Steel-look windows
Very slim frames with glazing bars that mimic traditional metal windows, adding thermal performance and double glazing to the classic look.
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.
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 Leicestershire: questions
How do I look after powder-coated aluminium windows?
Clean powder-coated aluminium windows with warm water and a mild, non-abrasive detergent a few times a year, then rinse and dry. Avoid scouring pads, solvents and pressure washers close to the seals. Keep drainage slots clear and put a little light oil on hinges and locking points. Near the coast, more frequent washing removes salt deposits.
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.
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 much do aluminium windows cost?
The cost of aluminium windows depends on the number and size of windows, the profile system, how many sashes open, the colour and finish, the glass and the access. They generally cost more than equivalent uPVC because of the material and factory coating. See the guide prices for typical ranges; the written quote fixes the price for your exact specification.
