We supply and fit aluminium windows, doors and glazing repairs across Southampton and the surrounding Hampshire area, covering SO14–SO19, SO30–SO32, SO40. Typical supplied-and-fitted cost for a standard 1200 × 1200mm casement in Southampton is £770–£1,160.
Southampton housing is dominated by Victorian terraces in Portswood and Shirley, 1930s semis in Bitterne and Highfield, and waterside apartments along the Itchen — salt-laden air makes marine-grade finish a real specification issue, not a sales upsell. That matters, because the right window is the one that suits the stock — not the one the salesperson has in the van.
Southampton has conservation areas including Old Town, Bedford Place and Highfield. Replacing windows is permitted development for most houses, but a conservation area with an Article 4 direction removes that right, flats have no permitted development rights at all, and a listed building always needs listed building consent.
Check with Southampton City Council before you order anything. A pre-application conversation costs nothing; an enforcement notice costs a great deal. In practice, conservation officers object to thick sightlines rather than to aluminium as a material — which is exactly why a slim aluminium heritage profile is routinely accepted where uPVC is refused.
Southampton sits close enough to salt water that the powder-coat specification genuinely matters. A standard polyester powder coat within a mile or two of the coast will begin to chalk and pit years before its guarantee expires. Specify Qualicoat Seaside grade, which uses a heavier pre-treatment developed for marine environments, and rinse the frames with fresh water a few times a year.
This is a specification issue, not an upsell. If a quote for a coastal Southampton property does not mention marine-grade coating, ask why.
Southampton sits in the South East pricing band, which runs at roughly 110% the national average. These are supplied-and-fitted ranges including VAT.

Most window faults are repairs, not replacements. A misted unit is £80–£190 and keeps your existing frame. A handle is £40–£100. A dropped sash is usually a hinge, at £60–£110. And if a window is broken or a door will not lock, we treat it as an emergency — same day where a fitter is free in your SO postcode, next day everywhere else.

For most houses, no — it is permitted development. But Southampton has conservation areas including Old Town, Bedford Place and Highfield, so check with Southampton City Council before you order: a conservation area with an Article 4 direction removes permitted development rights, and a listed building always needs consent.
