The Brief

A homeowner in Preston wanted to upgrade to a modern, high-efficiency boiler. The previous boiler had reached the end of its life and was becoming unreliable, so the household was looking for a dependable replacement that would keep the home warm and lower their running costs. They chose a Worcester Bosch combi boiler for its reputation for reliability and energy efficiency.

What We Did

Our work included:

  • Removed the old boiler: Safely disconnected and removed the previous boiler, ensuring all gas and water connections were properly isolated.
  • Prepared the installation site: Checked the flue and gas inlet to confirm they were suitable for the new boiler. Made minor adjustments to pipework to ensure a proper fit.
  • Installed the new Worcester Bosch combi boiler: A modern high-efficiency unit with built-in condensing technology for maximum efficiency and lower running costs.
  • Carried out a free chemical flush: Flushed the heating system to clear out sludge and debris, so the new boiler runs cleanly and efficiently from day one.
  • Connected all pipework: New gas and water connections made to manufacturer specifications and British standards. 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 work correctly.
  • Registered the warranty and handed over: The manufacturer warranty was registered, and the homeowner was shown how to operate the new boiler, adjust temperatures, and what to do if they encounter any issues.

The Result

A modern, reliable heating system that delivers consistent warmth and hot water. The Worcester Bosch boiler has excellent efficiency ratings, reducing the household's annual heating costs. The homeowner is confident in the reliability of their new system and has received a full manufacturer warranty. The home was back up and running within two days.
