We begin with an assessment of your property and requirements, then confirm the agreed scope, price and schedule. On the day, we remove the old unit where applicable, fit the new boiler, and complete commissioning and safety checks. We finish with a clear handover so you know how to run the system efficiently. How do I know if my boiler needs replacing rather than repairing? If you are seeing frequent breakdowns, rising running costs, inconsistent heating, or poor hot water performance, replacement may be the better long-term option. We will explain the likely causes and the cost and reliability trade-offs in plain terms. The aim is a decision you feel confident about, not guesswork. How long does a boiler installation or replacement usually take? Timescales depend on the complexity of the job and any system work needed to support a reliable result. We will give you a realistic timeframe before booking and keep you updated if anything changes. Our focus is to complete the work efficiently without cutting corners on testing and commissioning. Will there be disruption in my home or premises during the work? There will be some disruption while we isolate services and carry out the installation, but we plan the work to minimise downtime. We work tidily, protect the area where practical, and keep you informed about what is happening and when heating and hot water will be back on. A clear finish and clean handover are part of the service. What paperwork and reassurance do I receive after installation? You will receive the relevant documentation for the work completed, along with guidance on operating your new boiler and controls. We will also talk you through any next steps, such as recommended servicing intervals, to keep performance and safety on track. If you have questions after the visit, you will know who to contact.
