Companies House matched 35 of 116 businesses on an exact name with a corroborating registered address. Firms are seeded by trading name, which is how a business presents itself rather than what it is registered to do — so the mix below is often broader than the index title suggests. A company may register several SIC codes, so these counts sum to more than the number of firms. Median company age is 9.8 years, ranging from 0.2 to 45.8. Recorded alongside the measurement and carrying no weight in any score.

Which double glazing company in Bristol has the best website?

Section titled “Which double glazing company in Bristol has the best website?”

Bristol Windows And Doors tops the Q4-2026 index with a Digital Visibility Score of 73/100. Each firm has a full diagnostic scorecard linked from the table above.

Every score follows the same six-pillar methodology: Speed & Core Web Vitals (20%), Technical foundation (20%), Local presence (20%), Visibility (15%), AI search presence (15%) and Content & trust (10%). Each pillar links to the knowledge-base article that explains what it measures; the statistical methods behind the scoring are written up separately. Download the full dataset: JSON · CSV.

The index is compiled and published by PYC, a search consultancy run by Phil Yarrow. It exists because the questions it answers — who is actually visible in a local market, and by how much — were being answered with opinion. The collection and scoring code is open source, so any figure here can be recomputed rather than taken on trust.
