A heat-pump quote with several subcontractors: name the main point of contact

A heat-pump proposal involving several trades should identify who coordinates the quotation, who answers each technical question and who can approve changes. One named contact helps route questions, but it does not make that person the technical designer or contracting party for every trade.

Write these roles into a project contact sheet and link it to the relevant quotation versions. Keep commercial responsibilities consistent with the actual agreements. This is a coordination template, not legal advice or a transfer of another contractor's obligations.

Distinguish coordination from technical responsibility

A renovation may involve a heating installer, electrician and building contractor. Their interfaces need attention even when each individual proposal looks complete. Buildwise provides background on heat pumps in renovation for the technical assessment; the contact sheet below only organises communication.

Use named people and a backup contact where appropriate. Replace general labels such as “the office” with a role that the owner and site team can actually reach.

Do not assume the person who forwards an email has approved its contents. Likewise, the owner naming a preferred contact does not automatically change the contract structure.

Find the gaps between proposals

Read the quotations together. For each interface, identify the deliverable needed by the next trade and who confirms it. Examples include access arrangements, availability of technical documents and completion of agreed preparatory work.

A useful interface entry has a reference, a question, an owner, a due date and a status. “Electrical preparation pending” is too vague: record the specific confirmation the heating installer needs, without inventing the technical answer on their behalf.

Route changes through a visible decision

Suppose an access constraint leads to a proposed extra lifting service. The main contact should obtain the relevant proposal, identify any programme effect and send it to the agreed decision-maker. The example does not imply that lifting is required or suitable on every project.

Record the accepted version and communicate the decision to the affected parties. If the price or consequence is still unknown, keep the item open rather than labelling it approved because the client acknowledged the message.

Close the loop at handover

Before the final project review, collect the documents each party agreed to provide and record outstanding items with their owners. Confirm where the client should direct an operational question and where they should raise a quotation or invoicing query.

Review the contact sheet whenever personnel or scope changes. A document with last month's coordinator can create the same confusion as having no coordinator at all.
