Who this service is for

This is best suited to properties that are not connected to mains gas and rely on LPG for space heating and hot water. It is commonly used by homeowners planning a reliable replacement before a breakdown, landlords needing a compliant upgrade, and small commercial sites that want dependable heating with minimal disruption.

How the installation is delivered

Work usually starts with a site visit to confirm appliance location, flue route, ventilation requirements, existing pipework sizing, and the condition of the wider system. You then receive a clear plan for what will be changed and what will stay, so there are no surprises on the day.

On installation day, the old boiler is isolated and removed (if required), the new boiler and flue are fitted, and the system is connected and tested. Commissioning includes safety checks, setting up controls, verifying correct operation, and recording benchmark details so the boiler is ready for regular servicing.

After installation: support and ongoing performance

You will be shown how to run the heating, adjust timers and temperatures, and spot early warning signs of a fault. For best efficiency and safety, annual servicing is recommended, and any system improvements identified during the install can be planned as follow-on work.

Frequently Asked Questions

Can you install an LPG boiler in any property?
Most off-gas properties can have an LPG boiler, but the appliance location, flue route and ventilation must meet current standards. A site survey confirms feasibility and identifies any upgrades needed before installation.
Do I need to replace radiators or pipework as well?
Not always, but the existing system must be compatible and in good condition. If pipe sizing, controls or radiator output are limiting performance, you will be advised before work starts.
How long does an LPG boiler installation take?
Many straightforward replacements can be completed within one to two days, depending on access and any system upgrades. New installations or changes to flue routes and pipework can take longer.
Will I receive the correct safety and compliance paperwork?
Yes, commissioning records and relevant certification are provided after the boiler is safely installed and tested. Where required, the installation is notified in line with Building Regulations.
Do you handle the LPG tank or cylinder supply?
The boiler installation focuses on the appliance and your heating system connections. If changes are needed to the LPG supply pipework or regulator arrangements, this will be discussed during the survey so responsibilities are clear.
