Boiler Repair Planning Tools

Boiler visit information checklist

Prepare information for a heating engineer without opening the boiler or attempting a repair.

Tick the preparations you have completedNote the make and model from accessible paperwork or the visible label.Write down the exact fault code shown, without repeatedly resetting the appliance.Note whether heating, hot water or both are affected.Record when symptoms started and whether they are intermittent.Gather the last service record and any warranty paperwork.Tell the engineer about visible leaks or unusual noises without touching hot or electrical parts.

Assumptions and limits

This does not diagnose a boiler or recommend adjustments. Do not remove the casing or work on gas parts. If you smell gas or suspect carbon monoxide, leave the area and call the National Gas Emergency Service on 0800 111 999 from a safe place; do not wait for an enquiry.

Select what you want to arrange to prepare a clear request for a qualified engineer.

What are you planning?

A breakdown or fault

Give the model, visible fault code and symptom history.

Say whether the appliance is under warranty before authorising work.

Ask how diagnosis, proposed parts and approval for additional work will be handled.

A routine service

Provide the model, service history and any current concerns.

Ask what the service includes and which records will be supplied.

Disclose an existing fault rather than assuming a routine service includes repairs.

A visible leak or pressure concern

Note the visible location and when it occurs without opening the casing.

Use the manufacturer instructions only for permitted user actions; do not adjust components based on this tool.

Ask the engineer to assess the cause and explain any proposed repair.

Assumptions and limits

The appointment type is a planning choice, not confirmation that an appliance is safe to use. Gas work requires an appropriately qualified Gas Safe registered engineer. For gas smell or suspected carbon monoxide, leave the area and call 0800 111 999 from a safe place; do not wait for an enquiry.
