How Much Does It Cost to Convert a Conservatory Roof?
£5,000 – £15,000
per job
Converting a conservatory roof costs between £5,000 and £15,000, replacing the old polycarbonate or glass roof panels with a solid tiled or lightweight insulated roof system. A replacement conservatory roof dramatically improves thermal performance, reduces noise, and makes the space usable year-round. Most conversion systems do not require planning permission as they fall within permitted development.

Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Roof size - a smaller lean-to conservatory costs less to convert than a large Victorian or Edwardian style structure
Roof system type - a lightweight tiled system costs £5,000-£9,000; a full solid insulated roof with internal plastered ceiling costs £8,000-£15,000
Structural assessment - older conservatories may need wall and frame reinforcement before a heavier roof can be fitted
Internal finishing - some systems include a finished ceiling; others leave plastering and decoration as a separate cost
Labour vs materials
Most conservatory roof conversions are completed in three to five days by a specialist team. Labour accounts for around 40-50% of the total project cost.
Repair or replace?
If the existing conservatory frames and base are structurally sound, a roof conversion is usually far better value than demolishing and rebuilding the whole conservatory. However, if the frames are degraded or poorly built, a full replacement may be more cost-effective long-term.
