What moves the price
Three factors that weigh on the bill
Surface area
The bigger the conservatory, the more steel and glazing it needs proportionally — the structure also needs reinforcing past a certain span.
Price my surfaceStructural complexity
A curved roof takes more ironwork than a flat-pitched structure, for the same floor area — see the Victorian conservatory.

Single glazing, double glazing, thermal break: the level chosen directly affects price and real everyday comfort.

What's usually not included in the price
Any masonry work (base, slab, junction with the existing façade) and electrical wiring are costed separately depending on your house — to be explicitly clarified in the quote. Delivery is also costed by distance from the workshop.
Tell us the style you're after, the surface you want, and your façade's existing openings; a photo of the site helps the workshop refine the range from the first exchange, with no prior visit or commitment on your part.
Ask for pricingFrequently asked questions
Is the quote free?
Yes, no charge applies to get a price — the form is only there to pass the workshop what it needs to put together an accurate range.
Does the price include the planning paperwork?
The workshop can supply a dimensioned plan and technical description for your declaration or planning-permission file, but filing it stays your responsibility — see our dedicated page.
Why does the price per m² vary so much by glazing?
Single glazing with no thermal break costs less upfront but makes for an uncomfortable room once heated — thermally broken double glazing stays the recommended setup for year-round use, see our detailed comparison.
