Aluminium Windows for Portsmouth homes and sites
Windows are usually a whole-house order rather than a single opening, which means colour consistency and survey accuracy matter more than lead time. We make every frame to your surveyed sizes in one batch so the colour and finish match across the property.
We supply aluminium windows across the PO postcode area and the rest of Hampshire — Chichester, Southampton and Winchester are all on the same delivery run, so if you are coordinating more than one property it is worth ordering them together.
Portsmouth is coastal, so specify the marine-grade coating. It is the difference between a coating guarantee that means something within sight of salt water and one that does not.

Aluminium Windows in Portsmouth — questions we get asked
What U-value can I get on aluminium windows in Portsmouth?
From 1.4 W/m²K depending on the glass specification, which comfortably meets current Building Regulations for replacement windows. We will confirm the exact figure for your glass build-up on the quote.
Can I have different colours inside and out?
Yes — dual-colour is a standard option. A dark exterior with a white or light grey interior is the most common combination, and it costs less than you would expect.
How quickly can you deliver aluminium windows to Portsmouth?
10–20 working days from confirmed sizes. Portsmouth is roughly 207 miles due south of our Leeds factory — about 5 hours on the M1 and M25 — so delivery is by planned long-haul runs or palletised freight, depending on order size. Larger orders go on a dedicated run; smaller ones travel palletised on a tracked service.
Do you offer trade prices on aluminium windows in Portsmouth?
Yes. Installers, builders and fabricators across the PO area — Portsmouth, Chichester, Southampton and Winchester — can open a trade account for published trade pricing, a named contact, and delivery to site or yard.
