Every man-day is priced at exactly £30. A 20% contingency is added to cover bug fixes and edge cases.

Yes. The price you see on the costing page is the price you pay. The 20% contingency is included to cover any unexpected complexity, so there are no change requests or overruns.
The 20% contingency covers most scenarios. If a fundamental requirement was missed during specification, we would discuss it with you openly. This is why we encourage thorough review of all specification documents before approving the build.
