Prepare for loss of heating and hot water, protect access routes, and reserve time for a proper controls demonstration and document handover. Installation is not complete when the casing is on the wall.

Before the team arrives

  • Confirm arrival window, expected duration and named contact.
  • Clear the boiler, cylinder, radiators, stopcock, meter and route between them.
  • Protect valuables, floors and pets; agree who supplies coverings.
  • Plan for vulnerable occupants and temporary loss of heat/hot water.
  • Photograph existing finishes and meter readings.
  • Reconfirm parking, keys, alarm and waste arrangements.
  • Keep the written specification and variation process available.

During the work

Ask before any change to location, model, flue, controls or quoted scope. Record approved variations in writing with cost and time impact. Do not enter the work area or interfere with isolated services.

The team may drain and clean the system, alter pipework, fit controls, commission combustion and balance emitters depending on the job. The exact sequence varies.

Handover checklist

Item Confirm
Boiler and controls Exact models match the agreed specification
Operation Heating, hot water, schedules and overrides demonstrated
Settings Commissioned values and who may change them
System Pressure, radiator operation and known limitations
Records Commissioning checklist and test results where supplied
Notification Responsible business and expected certificate
Guarantee Registration confirmation and service conditions
Workmanship Term, contact and exclusions
Waste/making good Completed or documented outstanding work
Final payment Trigger matches the contract

In England and Wales, qualifying gas appliance work is notified through the appropriate route and a compliance certificate follows. Other nations differ. Ask what applies before installation.

After the team leaves

Use the system as demonstrated and record unexpected codes, pressure loss, leaks, noise or rooms not heating. Contact the installer rather than altering engineer settings. Keep all documents together for servicing, claims and a future sale.

Frequently asked questions

How should I prepare the work area?

Clear safe access to every agreed location and route, remove valuables and plan for service interruption. Do not dismantle the existing appliance.

Which documents and demonstrations should I receive?

The exact list varies, but typically includes commissioning information, control manuals, invoice, guarantee registration, service requirements and applicable compliance notification.
