Planning driveway replacement
Replacement pricing separates the new driveway from breaking out the old surface. Existing foundations may be retained only after assessment.
Do not pay for disposal twice if removal and cart-away are already included in the installer’s rate.
Measuring the work for this calculator
Measure the length and width of the work area in metres. Split an irregular outline into rectangles and add their areas. Where a depth or unit-count field is provided, it gives a separate quantity check; it does not decide the correct construction specification.
What the driveway replacement estimate covers
The selected surface guide is multiplied by the measured area. It is an early installation allowance, not a named-product quotation. Ordinary preparation must not be added twice. Existing-surface breakout, abnormal ground, engineered drainage, boundaries and highway work need their own agreed scope where excluded.
The first guide option is gravel replacement. Its allowance is £40–£70 for the relevant unit shown in the result. This is a published-guide starting point; it is not a price offered by a contractor on this website.
Choose the specification and separate allowances
The available work options are gravel replacement; tarmac replacement; concrete replacement; block paving replacement; resin-bound replacement. Select the one that matches the proposed scope before comparing the result.
The project controls include:
- Existing hard-surface removal.
Reading the budget breakdown
The results show the measured quantity, the selected work allowance and any separately selected items. A volume, unit count or coverage result is a quantity check, not a construction design. Where the model uses a minimum visit allowance or whole bags, the displayed total will not fall in direct proportion to a very small area.
Use the optional contingency to make a separate budget provision. Add a quoted fixed allowance only for work outside the model’s stated scope. Check the VAT basis before selecting the VAT adjustment.
Compare quotations for driveway replacement
Give contractors the same measurements and work description. Ask them to identify the main work, preparation, disposal, access requirements, drainage and any making-good that applies to this project. An apparent saving can simply mean that a different part of the scope has been priced.
Do not pay for disposal twice if removal and cart-away are already included in the installer’s rate. Keep the agreed specification with the quote, including any exclusions and the way changes discovered during the work will be authorised.
