A well-run heat pump project begins before any installer arrives with tools. A survey, system design, permissions and customer information should all be in place before work starts.
1. Survey and heating design
The property is assessed for heat loss, existing radiators, hot-water demand, outdoor positioning and electrical requirements. An appropriate design is agreed before equipment is ordered.
2. Proposal and eligibility
The quote should identify the scope, any radiator changes, cylinder, controls and making-good. For England and Wales, an eligible Boiler Upgrade Scheme installation is applied for by the participating installer.
3. Safe installation work
The team may carry out plumbing, electrical and outdoor works, using suitable access arrangements and safety controls. Timescales depend on the condition and layout of the property.
4. Commissioning and handover
The system needs testing, balancing, controls set-up and a clear explanation of operation. Ask for relevant certificates, warranties, performance information and who to contact for support.

These are general UK homeowner considerations, not a quote, technical design or funding decision. For current rules, see the official or independent guidance for this topic. The right answer depends on your property and the latest scheme conditions.
