Secondary Glazing cost in Portsmouth

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	£650 – £1,600

Prices are estimates derived from verified Portsmouth 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.

Portsmouth note: Conservation-area jobs in Southsea carry a premium; outer estates offer straightforward, lower-cost replacements.
