What is changing?
Explain whether this is a replacement in the same position, a move to another room or part of a wider renovation. Mention any hot water cylinder, planned bathroom changes and other heating work you want considered.
What does the home need?
Describe the property and household hot water use without trying to select an output yourself. A room count is useful context, but a suitable specification requires assessment of the actual home and system.
What is included in the quotation?
Ask about the boiler and controls, pipework, flue arrangements, removal of old equipment and making good. Clarifying the scope helps you compare proposals that might otherwise appear similar.
What needs to be ready?
Discuss access, other trades and whether the property will be occupied. If the job depends on building work, agree the sequence before confirming an installation date.
What happens after installation?
Ask about the handover, operating instructions, documentation and future maintenance requirements for the chosen appliance. Keep those records with the quotation and job information.
