We ar the leading box sash window information website! You can count on us for unbiased guides, and company reviews.
We mostly focus just on UK (especially London based) sash window companies. This is just because that is what our website readers seem to be interested in. We have no affiliation with any of those companies, they are just provided as a free service.
