The Brief

A family home in Ealing had an ageing boiler that was becoming unreliable and expensive to run. It was struggling to keep the house warm and the homeowners were worried about being left without heating over winter. They wanted a modern, efficient replacement that would lower their bills and give them long-term peace of mind, and they chose a Vaillant boiler for its reputation for reliability and its 10-year warranty.

What We Did

Our work included:

  • Surveyed the existing system: We assessed the old boiler, the pipework and the household's hot water needs, then recommended the right Vaillant model and gave a fixed quote before any work began.
  • Removed the old boiler: The old, unreliable unit was safely disconnected and removed, with all gas and water connections properly isolated, and taken away for disposal.
  • Prepared the installation: We checked the flue and gas supply were suitable for the new boiler and made minor adjustments to the pipework to ensure a clean, proper fit.
  • Installed the new Vaillant boiler: A modern, high-efficiency Vaillant combi boiler was fitted to the manufacturer's specification, with all connections tested for leaks.
  • Commissioned and tested: The boiler was filled, pressurised and thoroughly tested. All controls, thermostats and safety devices were verified to be working correctly.
  • Registered the warranty and handed over: We registered the 10-year manufacturer warranty on the homeowners' behalf, issued the paperwork, and showed them how to operate and adjust their new boiler.

The Result

A modern, reliable heating system that delivers consistent warmth and hot water across the home. The new Vaillant boiler runs far more efficiently than the old unit, reducing the household's heating costs, and the 10-year warranty gives the homeowners real peace of mind. The job was left clean and tidy, with all certification and warranty documentation in hand.

Job Duration: Approximately one to two days from initial survey to final commissioning and handover.
