The Heritage Window Company

We are specialists in slimline aluminium windows and doors, replacement of steel windows (including Crittall® windows*) and aluminium windows in a variety of colours.

Retain the distinctive charm of your steel windows with aluminium double glazing from The Heritage Window Company. All windows are designed and built here in the UK and we are very proud to promote British engineering and quality throughout our products.

Our unique Benenden window is the slimmest aluminium window available on the market, designed to replace traditional steel windows or as a bespoke window for new build projects.

The latest steel window replacements (including Crittall® windows*) fit perfectly into your original timber frames, or direct to brick and stone, providing the performance of modern double glazing whilst maintaining the period character of your home.
