Costs & agreements
Comparing demolition quotes: look beyond the total price
Two demolition quotes can only be compared properly if they describe the same work. Check preparation, protection, waste disposal and handover in particular. A lower total may mean an item will be charged separately later.
Start with one specification for all providers
List what must go and what must stay in each room. For example, distinguish between removing only kitchen cabinets, also removing the tiles, and removing the floor as well. State the floor level, the route outside and whether the property will remain in use during the work. Send every provider the same photographs and drawings.
Ask which assumptions the price is based on. Has the substrate been inspected? Has the structure been assessed? A quotation based on photographs may still require investigation or a site visit. Have this made explicit before placing the order.
Compare these items separately
| Element | What would you like to see? | Ask if anything is unclear |
|---|---|---|
| Scope boundary | Rooms, materials and parts to retain | Are adhesive residue, skirting boards and fixings also removed? |
| Preparation | Required surveys and the party responsible | Who arranges the drawings, calculations and procedure check? |
| Protection | Floors, access route and dust screening | Which parts of the property will be screened off? |
| Installations | Making safe and any necessary alterations | Is the installer included? |
| Structure | Supports, steelwork and inspections where needed | What structural work has been included in the budget? |
| Drainage | Waste streams, transport and processing costs | Are the skip, hire period and any placement charges included? |
| Handover | A clearly agreed end result | Is the substrate also ready for the next tradesperson? |
| Pricing agreements | VAT, provisional sums, payment dates and validity | Which items do not yet have a fixed price? |
| Changes | Procedure for unexpected circumstances | Who approves extra work, and when? |
A provisional sum is an item to be adjusted later
A provisional sum is an estimated amount for work or materials whose scope is not yet fixed. Ask which assumptions have been used and how the final cost will be calculated. For example, a waste allowance means little without a description of the waste type, quantity and transport.
Also agree what will happen if an unknown pipe or suspect material is found behind a wall. A clear agreement includes a point at which work stops, an assessment and approval before additional work continues. This helps avoid misunderstandings, although it does not remove unforeseen conditions.
Use the handover condition as your final point of comparison
'Swept clean' does not automatically mean that a floor is level, free of adhesive or ready for new tiles. Have the required finish specified for each element and agree it with the contractor who will carry out the next stage. Also ask which photographs, waste documents or structural documents will be provided at handover, where relevant to the work.
Frequently asked questions
Is a fixed price always better?
That depends on the situation assessed and the specification. A fixed price for an unclear scope offers little certainty. First establish what the price covers and which exceptions apply.
Can I calculate an exact price online?
A reliable project price requires details of the scope, materials, access and necessary preparation. The cost pages help with initial planning; the quotation records the specific work for your project.
