A borehole drilling quotation should explain the work stages and what is uncertain. Do not assume that drilling automatically guarantees a particular water yield or drinking-water quality.
What to check
Ask an appropriately qualified provider about site assessment, permissions, drilling charges and completion documentation. Clarify which costs depend on depth or site conditions and whether casing, testing and equipment are included. Discuss the process if the result differs from expectations. Obtain suitable water-quality testing before relying on the source for drinking.
Questions to ask
- Which charges vary with conditions?
- Are yield and water-quality testing included?
- What happens if the borehole is unsuccessful?
Compare written proposals against the same brief
Give shortlisted providers the same description and ask them to identify exclusions. Separate assessment, labour, materials and any follow-up that applies. A lower total is difficult to judge if it leaves essential work unspecified. Agree who can approve changes and how the finished job will be checked. For work affecting safety or structural performance, use the appropriate qualified professionals and required approvals throughout, not only after a problem appears.
