This page provides general practical guidance and does not replace project-specific legal, engineering, planning, ecological, asbestos or waste advice.
The short answer
Prices start from £1,500 for prefabricated or sectional garages. Your final written quote depends on the garage, access and work required. Waste disposal is itemised separately. This starting figure applies to prefabricated or sectional garages with straightforward access — brick, block, concrete-panel and other construction types require an individual quotation. A written quotation covers the agreed scope: garage removal, waste removal and disposal, optional slab removal (from £1,000 extra where included), and foundations or additional groundworks where required. Foundations are individually quoted.
Why it matters
The variables that affect cost are often invisible in a photograph. Construction type, roof materials, reinforcement in the slab, proximity to retained structures and the distance from the work area to the loading point all affect the method, programme and waste arrangement. A price that does not account for these is not a reliable basis for planning. Waste disposal is a separate cost that depends on the volume, weight and type of material — it is itemised in the written quotation rather than bundled into a single figure.
Information that may be needed
To prepare a written quotation we need: project postcode, photographs of all elevations and the roof (where safe), approximate dimensions, construction type (prefabricated, sectional, brick, block or other), access details including any parking or loading restrictions, whether the slab should remain or be removed, and any known information about services or roof materials. If the garage is attached to another structure, a photograph showing the junction is useful.
What can affect the scope
Construction type is the primary variable — prefabricated and sectional garages are a different scope from brick, block or concrete-panel structures. Attached garages require additional sequencing and protection of the retained structure. Roof covering affects both the removal method and the waste classification — suspected asbestos-containing materials must be sampled by a competent professional before work begins. Slab removal depends on thickness, reinforcement and access for breaking equipment. Foundation removal is assessed individually. Access for skips or a grab lorry, manual carrying distance from the work area to the loading point, and the required finished condition all affect the final cost.
When specialist input may be needed
An asbestos professional is required where roof or other materials need sampling before work begins — materials cannot be identified safely from photographs alone. A utility provider or qualified electrician may need to confirm service isolation where services run to or through the structure. Where the garage is attached to a retained building, a structural engineer may be needed to advise on the junction and any temporary support required.
