Summary
Conservatory removal is one of the simpler structural alteration jobs to price, but customers consistently underestimate the waste-handling component. A typical 3m × 3m conservatory generates 2–4 cubic metres of mixed waste: glass (recyclable), aluminium frame (high scrap value), uPVC frame (recyclable in segregated streams), polycarbonate or glass roofing (recyclable), timber or stud-wall components, and the dwarf wall (typically 600mm brick or block on concrete strip foundation). Each waste stream has different disposal costs.
The two distinct scopes are removal-only (the customer doesn't reinstate the wall) and removal-plus-reinstate (the wall and patio doors are made good, sometimes a new external wall is built to re-create what was there before the conservatory was added). The price difference is significant.
This guide covers labour bands, waste handling, the structural reinstate scope, planning and Building Control considerations, salvage value offsets, the asbestos question on older bases, and worked pricing examples.

Detailed Guidance
Tear-Down Scope
Standard tear-down (no reinstate) sequence:
- Disconnect services — radiators (if any), electrical (lighting, sockets), water (if a tap is in the conservatory)
- Remove glazing — break down or carefully remove panels for salvage; many double-glazed units can be sold to specialist buyers
- Strip roof — polycarbonate panels (lift out), glass panels (carefully remove)
- Disassemble frame — aluminium or uPVC, lift sections, sort by material
- Remove dwarf wall — typically 600mm brick or block; can be hand-demolished with a sledgehammer or mini-breaker
- Lift floor — concrete slab if present; sometimes a screed only
- Break out concrete strip foundation — minor excavator or hand breaker, depending on size
- Skip/load waste — segregated by material where possible to reduce skip costs and increase recycling value
- Clean and tidy site — final sweep, make safe any exposed services
Waste Streams and Costs
Waste from a typical 3×3m conservatory:
- Glass: 60–150kg — segregated glass skip £80–£140
- uPVC: 80–150kg — mixed plastic skip or builders skip
- Aluminium: 80–150kg — scrap merchant offset £600–£1,200 per tonne
- Roof panels (polycarbonate): 30–60kg — builders waste
- Concrete dwarf wall + strip foundation: 0.5–1.5 tonnes — heavy waste skip £150–£250
- Insulation (if present): typically rigid PIR or rockwool — builders waste
Segregating reduces total cost: a single 6-yard builders skip with mixed waste at £270 is cheaper than five segregated skips but loses the recyclable value. Most contractors run one builders skip and one segregated metal collection for aluminium.
The Reinstate Decision
After tear-down, the host wall faces the garden. Three options for the customer:
Option A: Doorway only (existing patio doors + adjacent wall reused):
The most common. The original patio doors or sliding doors remain; the wall around them is repaired, plastered internally, repainted. Cost: £200–£400 above tear-down.
Option B: New patio doors / French doors:
The conservatory had a patio-door opening into the host wall; the customer wants the door upgraded as part of the work. New French doors or bi-fold doors are installed. Cost: £1,300–£2,500 above tear-down depending on door spec.
Option C: Full reinstate as solid wall:
The original house wall had a normal small window. Conservatory removal means rebuilding the original wall, adding a window, plastering and decorating. Cost: £1,500–£3,000 above tear-down.
Always discuss the post-tear-down look. Customers who haven't considered what the wall looks like once the conservatory is gone are surprised.
Salvage Value — Worth Claiming
Salvage value commonly offsets the disposal cost partially:
- Aluminium frame (8m perimeter conservatory) at ~100kg = £60–£120 at current scrap prices (subject to market rate)
- Glazed units (double-glazed sealed) — specialist buyers pay £20–£50 per panel for resale
- Roof panels (uPVC frame) — limited resale value, typically scrap
- Brick from dwarf wall — typically scrap, but matched-period bricks may be saleable
Claim and disclose: include a salvage line on the quote either as a deduction ("£80 salvage offset on aluminium frame") or as a stated retention by contractor. Transparency avoids disputes.
Planning and Building Control
Planning permission:
- Conservatory removal is "de minimis" — does not require planning permission unless the property is listed or in a Conservation Area with an Article 4 Direction
- Listed buildings: removal of a non-original conservatory is usually permitted but the host wall reinstatement needs LBC if any structural change is involved
- Conservation Areas: removal usually OK; reinstatement may need design approval
Building Control:
- Tear-down alone: usually no notification required
- Reinstatement of wall structure: notification required (this is "structural work")
- New door / window opening: notification required (Part L thermal, Part Q security, Part B fire safety on flats)
For the typical "tear down + reinstate existing door" scenario, no Building Control notification is needed because no structural change is happening. For "tear down + new patio doors" with replacement opening, the doors themselves are FENSA / Certass notified by the installer.
Asbestos Considerations
Pre-2000 conservatories may contain asbestos in:
- Cement-based dwarf-wall panels (uncommon but possible on pre-1985 installations)
- Floor tiles or sheet flooring
- Insulation around connections to host wall
- Old electrical components (e.g. switch backings)
If the property is pre-2000 and uncertain, recommend an asbestos survey before any demolition. Cost: £150–£400 for a screening survey. Control of Asbestos Regulations 2012 require asbestos awareness before demolition; non-licensed work is permissible for some materials but licensed contractors are required for licensable asbestos.
Common Site Overruns
- Hidden steel beam in dwarf wall — supports the conservatory roof but bears into the host wall; removal needs structural calc.
- Buried foundation extends beyond conservatory footprint — strip footings can run 300–500mm beyond the wall line; more concrete to break out.
- Tile floor over original patio — needs careful removal to avoid damaging original surface beneath.
- Customer changed their mind about reinstatement — quote a re-scope; don't proceed without written confirmation.
- Bad weather delays — tear-down with the roof off is rain-exposed; flooring and walls need protection.
Frequently Asked Questions
Does the customer save money by demolishing themselves?
Possibly, but it depends on their tolerance for difficult disposal. The disposal-cost share is £200–£500 even on a small conservatory, and DIY demolition without proper tools tends to take a weekend or more. Most customers find paying £600–£900 for a professional tear-down preferable to a weekend of strain plus skip hire.
Is a permit needed for skip placement on the road?
Yes — most local authorities require a £30–£70 permit for skip placement on a public highway. Skips on the customer's drive/garden don't need a permit. Costs vary by council; check before quoting.
Can the conservatory base be reused for a future extension?
Unlikely. Conservatory bases are usually not insulated to current Part L standards, are often not deep enough for a habitable extension, and may not have the required damp-proof course (DPC) detail. A new extension typically requires new foundations and ground floor.
What about the windows and door in the existing wall?
If the conservatory was added in front of an existing patio door, that door usually remains. The internal wall finish (plaster, decorations) was likely altered when the conservatory was added; this needs making good after removal — typically a re-skim and repaint of the affected area. Budget £400–£800 for this.
How long does the whole process take?
Standard 3×3m tear-down: 1–2 days. Plus reinstate of existing patio door: +1 day. Plus new patio doors: +1–2 days. Plus brick wall reinstate: +2–3 days. Total for full reinstate jobs: 4–6 days.
