FAQ
Frequently Asked Questions
Do you provide the warranty and certification after installation?
Yes. Every installation includes a one-year workmanship guarantee from Pro Plumbers Ltd. Eligible boilers are registered with the manufacturer to activate their warranty, and we supply the relevant installation and commissioning paperwork for your records.
Must a Gas Safe engineer carry out the work?
Yes. Gas appliance installation must be carried out by a Gas Safe registered engineer to comply with the law and maintain warranty and insurance validity. Our engineers are Gas Safe registered and follow the correct commissioning and safety checks.
Will you handle flue and ventilation requirements?
Absolutely. We assess and, where necessary, install or modify flues and ventilation to meet Building Regulations. That includes routing, terminal positioning and any fire-stopping or ducting needed for a compliant, safe installation.
Do you remove the old boiler and what about system cleanliness?
We can remove and responsibly dispose of the existing boiler if agreed at the survey. For older systems we may recommend a powerflush to remove sludge and protect the new boiler — we can include that as a separate service if required.
How long does a typical installation take and what affects the timescale?
A straightforward like-for-like replacement is usually completed quickly, while system upgrades, flue relocations or work in hard-to-access properties can take longer. Timescale depends on property type, required pipework, controls and any remedial works identified at survey.
