Aluminium Windows for Kettering 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 NN postcode area and the rest of Northamptonshire — Northampton, Stamford and Bedford are all on the same delivery run, so if you are coordinating more than one property it is worth ordering them together.

- Our own fleet on planned long-distance runs — 103 miles south-south-east of Leeds, about 2½ hours on the M1 and A1
- Surveys at this distance are booked onto a planned route, so it is worth giving us as much notice as you can.

Aluminium Windows in Kettering — questions we get asked
What U-value can I get on aluminium windows in Kettering?
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 Kettering?
7–15 working days from confirmed sizes. Kettering is roughly 103 miles south-south-east of our Leeds factory — about 2½ hours on the M1 and A1 — so delivery is by our own fleet on planned long-distance runs. We will confirm the run date when your order is placed so you can plan the fit around it.
Do you offer trade prices on aluminium windows in Kettering?
Yes. Installers, builders and fabricators across the NN area — Kettering, Northampton, Stamford and Bedford — can open a trade account for published trade pricing, a named contact, and delivery to site or yard.
