Secondary Glazing for Listed Buildings
Can I assume internal glazing needs no consent?
Ask the relevant conservation authority about the proposed alteration and retain its advice with the project records.

Secondary Glazing for Listed Buildings — planning the work
For secondary glazing for listed buildings, frame position, opening access and the relationship to the original window affect the design. Agree panel operation and installation details after measuring the opening.
More questions
about this service.
Can historic glass be left untouched?
Retention may be possible, but any existing damage or needed specialist repair must be assessed independently.
How is the quotation worked out?
Include any primary-window repair or relocation of fittings as separate agreed items. The secondary system, opening arrangement, pane specification, dimensions and fixing surface affect price.
Does the original window need its own condition check?
An inner layer does not repair decay, broken glass or faulty hardware in the retained window; those issues must be identified independently.
What should be covered at handover?
Check panel movement, fit, seals and cleaning access.
