Calculator questions
Can I estimate selected rooms rather than the whole house?
Yes. Add only the rooms you want to renovate. Enter an area in m², or use length and width.
Can I choose individual renovation works?
Yes. Choose the work for each room, then adjust quantities if needed. Your result shows the priced work and anything that needs a separate allowance.
Does the estimate include VAT?
Yes. The result includes VAT and your chosen contingency.
What about layout changes?
Whole-home work is listed separately. Moving fittings or changing a layout needs a tailored quote.
