It confirms the appliance is burning gas safely, venting correctly, and running as efficiently as it should. Most boiler manufacturers recommend a service every year, and many make it a condition of their warranty. Regular servicing also spots worn parts and early warning signs, so they can be dealt with on your timetable rather than in the middle of a cold snap. Warm-Wise services boilers across Nantwich, Crewe, Sandbach and the surrounding area. Our engineers are Gas Safe registered (927370) and will explain clearly anything they find. ### Who it's for - Homeowners wanting a safe, reliable boiler - Owners of boilers under manufacturer warranty - Anyone who hasn't had a service in over a year - Buyers of a new home with an unknown boiler history ### Signs you need it - Once a year, ideally before winter - Boiler making new noises or smells - Pilot or flame looks different - Pressure keeps dropping ## What skipping a service can cost you A boiler can seem fine right up until it isn't. Missing services lets small, cheap problems grow unnoticed. ### Unsafe combustion Blocked flues or poor combustion can affect safety. A service checks these properly. If you smell gas, call the National Gas Emergency Service on 0800 111 999 first. ### Voided warranty Many manufacturer warranties require annual servicing. Miss it and you may pay for repairs that would otherwise be covered. ### Declining efficiency Dirt and wear make a boiler burn more gas for the same heat, quietly raising your bills. ### Winter breakdowns Worn components that could have been spotted in autumn tend to fail when the boiler is working hardest. How it works ## Our boiler servicing process - 01 ### Visual inspection We check the boiler, flue, pipework and controls for signs of wear, leaks or damage. - 02 ### Clean and check components Key internal parts are inspected and cleaned where needed. - 03 ### Combustion and safety tests We test the appliance is burning and venting safely and operating within the manufacturer's range. - 04 ### Report findings We explain what we found in plain English and flag anything that needs attention. - 05 ### Leave it running Boiler restored, area tidied, and advice given on anything to keep an eye on. What you get ## Why choose Warm-Wise for boiler servicing ### Safety confirmed Checked by a Gas Safe registered engineer. ### Warranty protected Keeps you in line with manufacturers' annual service requirements. ### Fewer breakdowns Worn parts spotted before they fail. ### Efficient running A clean, well-set boiler uses less gas. ### Honest advice We won't push repairs you don't need. ### Longer boiler life Regular care helps your boiler last. ## What's included in our boiler service ### Gas boilers of all common types We service combi, system and regular gas boilers. Worcester Bosch is our preferred brand for new installations, but we service other makes too. ### Flue and ventilation checks The flue carries combustion gases safely out of your home. We check it's intact, correctly terminated and unobstructed, and that ventilation around the appliance is adequate. ### System pressure, controls and radiators While we're there, we look at system pressure, the controls and how the radiators are heating. If there are cold spots or a system that would benefit from balancing, we'll tell you. ### Servicing alongside other work If you're planning bathroom, kitchen or electrical work, we can service the boiler during the same visit, saving you a separate appointment. ### Residential and commercial work Most of our boiler servicing work is in homes across Nantwich and South Cheshire, but we also fit out kitchen and bathroom showrooms for other businesses.
