Gloucestershire Double Glazing Digital Visibility Index — Q4-2026

Not every firm could be measured on every pillar (Q4-2026)

16 of the firms below are missing at least one pillar: Speed & CWV (89 of 99), Local presence (97 of 99), Content & trust (89 of 99). Where a pillar could not be measured for a firm it is excluded from that firm’s score and its remaining weights are renormalised, rather than scored zero — so those firms are ranked on less evidence than the rest, and their position should be read with that in mind. Affected: Shire Window Solutions, Q B D Ltd, ClearChoice Windows, Doors & Glazing Ltd, Original Sash Window Solutions, CK Steel & Aluminium Doors, Prior Products Cheltenham, Happy Glaze, Barry Hunt Windows Ltd., Cheltenham Bespoke Joinery Ltd, Gloucester Trade Frames Ltd, Outlet Trade Frames, Amos Joinery, Cleeve Window Centre, Heritage Sash Windows Ltd, UK Frame Solutions, K-ban Ltd. See the methodology.

The PYC Gloucestershire Double Glazing Digital Visibility Index ranks 99 double glazing companies in Gloucestershire on how well they perform online — website speed, technical SEO, local presence, search visibility, AI search presence and content & trust — each scored 0–100 to a single Digital Visibility Score. Measured 8 October 2026 to the published methodology.

As of Q4-2026, 16% of the 89 double glazing companies in Gloucestershire measured on Speed & Core Web Vitals score below 50 on mobile (PYC Gloucestershire Double Glazing Digital Visibility Index, measured 8 October 2026).

Search visibility against AI presence

Search visibility against AI search presence. The dashed diagonal is parity; a firm far from it is strong in one channel and weak in the other.

horizontal: search visibility →   vertical: AI presence ↑

Albany Windows Ltd is the widest split: AI engines name it far more readily than search surfaces it (AI 80, visibility 21) — brand without search. Those are different problems behind a similar overall score.

Reputation: reviews against rating

Google review volume (log scale) against average rating. Bubble size is review count. The rating axis starts at 3.9 so the cluster is readable; 7 firms rated below that sit on the floor, drawn hollow and named.

horizontal: reviews (log) →   vertical: rating ↑

Review volume spans 1 to 199 and ratings 1.8 to 5, yet the Local pillar separates these firms by only 45 points — the raw figures discriminate where the score does not. Most reviews: ACT Direct Ltd (199). Highest rating: 45 firms tied at 5.

Change between Q3-2026 and Q4-2026 on the 6 pillars measured in both quarters — Speed & CWV and Technical and Local presence and Visibility and AI search presence and Content & trust. The other pillars were not measured in Q3-2026, so no comparison is possible and none is drawn.

Hollow mark is Q3-2026, solid is Q4-2026. Showing the 12 largest of 172 changes. 392 readings unchanged and not drawn, across 12 firms that moved.

Adams Glass and Glazing Ltd' moved furthest: AI search presence down 100 points since Q3-2026. 172 of 564 comparable readings changed at all — which is what a quarter of movement actually looks like.

What the register says this cohort is

Companies House matched 22 of 99 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 15.6 years, ranging from 1.3 to 43.2. Recorded alongside the measurement and carrying no weight in any score.

Which double glazing company in Gloucestershire has the best website?

Albany Windows Ltd tops the Q4-2026 index with a Digital Visibility Score of 76/100. Each firm has a full diagnostic scorecard linked from the table above.

How this is measured

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.

Who publishes this

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.
