Frequently asked questions
Quick answers about quoting, coverage and next steps.
How quickly will someone contact me?
We aim to respond within 1 business day. If your project needs a site visit, we’ll confirm the next steps by phone or email as soon as possible.
Can you quote from drawings?
Yes. Share your drawings, ground investigation information (if you have it) and scope details. We’ll review what you’ve provided, confirm any assumptions, and then provide a quotation.
Do you work nationwide?
We support groundworks projects across the UK. Tell us your location and project type and we’ll confirm coverage and the right next step.
Can you help before planning is complete?
Absolutely. Even when planning/design isn’t final yet, we can review early information to help define scope, buildability and the practical programme before you commit to tender or mobilisation.
What project sizes do you cover?
We handle commercial projects across a wide range of sizes—small developments through to larger infrastructure and multi-phase schemes. Contact us with your brief and we’ll match the right commercial specialist.
What information should I have before requesting a quote?
Ideally: Building Regulations (or tender-ready) drawings, ground investigation, foundation design, drainage layout, access constraints, existing utilities information, programme dates and a clear scope of works. Incomplete packs force contractors to price risk — so quotes either come in high with contingency, or low with exclusions that create variations later. See our quote preparation guide for the full checklist.
