Project Costs — United Kingdom
Start with measured geometry and the supplier’s actual purchasing units. Round order quantities only after applying the specified waste allowance, then add material, labor, delivery and other costs without double counting. This directory groups project costs tools for United Kingdom; individual pages state their supported inputs and limitations.
Start with these tools
Home Addition Cost Calculator — United Kingdom
Build a scoped home addition budget from an explicit area rate and itemized allowances rather than a fabricated national price. GBP planning view; stated limitations apply.

Bathroom Remodel Cost Calculator — United Kingdom
Build a scoped bathroom remodel budget from an explicit area rate and itemized allowances rather than a fabricated national price. GBP planning view; stated limitations apply.
Kitchen Remodel Cost Calculator — United Kingdom
Build a scoped kitchen remodel budget from an explicit area rate and itemized allowances rather than a fabricated national price. GBP planning view; stated limitations apply.
Open a tool, check the displayed formula and enter values from the same period and measurement system. Currency defaults to GBP. Where a form offers metric and imperial units, changing the selector converts the entered measurements rather than relabeling the same number. Dated reference components are shown with their sources; unverified rules and prices are not silently treated as current local facts. Save distinct assumptions as separate scenarios and compare their inputs before their outputs. Shared links can disclose the input values they contain. The implemented expansion is still subject to its published scope-acceptance checks, including missing regional datasets and production-browser verification.

Frequently asked questions
Does this directory imply full local-rule coverage?
No. Each calculator states its scope. An implemented mathematical worksheet is not the same as a fully researched statutory calculator.
Where do the amounts come from?
Either your inputs or an explicitly named and dated reference component. Illustrative defaults are not supplier quotes or market averages.
Can I compare assumptions?
Use the individual calculator’s scenario controls. Read its formula, period, units and limitations before comparing results.
