Secondary Glazing cost in London
Secondary glazing fits inside the existing frame rather than replacing it — typically 40–60% cheaper than full replacement and the preferred route in listed buildings.
| Material | Glazing | Estimated price range |
|---|---|---|
| Aluminium | Double | £700 – £1,700 |
Prices are estimates derived from verified London casement baseline data (source: Checkatrade aluminium guide + Origin/Smart tier data) with a secondary glazing-specific multiplier applied. Fully-fitted supply and install including disposal and FENSA/Certass certification.
London note: Labour rates 30% above Midlands baseline; scaffolding costs inflate period-property jobs.
