Discover the answers to common boiler servicing questions to help keep your heating system running efficiently.
At Hynes Plumbing and Heating, our qualified engineers provide expert annual boiler servicing to ensure your system is operating at its best. Regular servicing helps prevent unexpected issues, improves energy efficiency, and extends the lifespan of your boiler.
Trust us for thorough, cost-effective boiler servicing that keeps your home warm and your heating system in peak condition.
Once a year, without fail! Think of an annual service as an MOT for your heating system. It keeps your boiler running safely, maintains maximum fuel efficiency, and prevents small issues from turning into freezing-cold winter emergencies.
A lot more than just a quick wipe down! When our Gas Safe or OFTEC registered engineers visit, they perform a comprehensive, multi-step health check of your entire heating system.
Our thorough service checklist includes:
Visual Safety Check: We inspect the boiler, flue terminal, and surrounding pipework for any signs of corrosion or minor leaks.
Deep Component Cleaning: Opening the boiler casing to clean internal parts like the burner and main heat exchanger.
Combustion & Flue Analysis: We use digital analyzers to make sure your fuel is burning cleanly and safely.
Gas Pressure & Flow Tests: Ensuring the unit operates at the correct pressure for peak performance.
A standard, professional boiler service typically takes 45 to 60 minutes. If we spot any minor issues during the inspection, we will always explain the problem clearly in plain English and provide a fix without any hidden fees or surprises.
Top Tip: To help our engineer work as quickly and safely as possible, please clear any clutter from the area or cupboard around your boiler before we arrive!
Yes, absolutely! Just because your boiler is quietly chugging along doesn't mean it's running efficiently or safely. Over time, hidden soot, dirt, and rust build up inside the system, causing the boiler to work twice as hard and slowly driving up your monthly energy bills.
Furthermore, a regular service is a preventative measure. It allows us to catch a tiny, £15 failing seal or valve in the summer before it turns into a massive, £500 emergency. If your heating has started making strange banging, gurgling, or whistling noises, it may be a sign of sludge build-up—in which case, you should look into our Reliable Power Flushing service.
If you are a Landlord: Yes! By law, you must have all gas appliances and flues in your rental properties serviced and inspected annually by a Gas Safe registered engineer. You will receive a Landlord Gas Safety Record (CP12 certificate) to prove compliance.
If you are a Homeowner: It isn't a legal requirement, but it is highly recommended. Neglecting your boiler can invalidate your manufacturer’s warranty, meaning you'll have to pay the full cost of any future breakdown repairs yourself.
No, they are actually quite different!
A Gas Safety Check is a targeted test designed solely to make sure your gas appliances are safe to use (checking that gas pressure is correct, safety devices cut off correctly, and there are no leaks).
A Boiler Service is a much deeper maintenance procedure where we open up the boiler, thoroughly clean the internal components, identify wear-and-tear, and tune the unit to improve its operating efficiency.
(At Hynes, our standard domestic service ensures both safety and performance are handled in one visit!)
No. For your own safety and to remain compliant with UK law, you must never attempt to service or repair a boiler yourself.
Gas Boilers: Must legally only be touched by a certified technician listed on the Gas Safe Register.
Oil Boilers: Should be serviced by an OFTEC registered technician.
Incorrectly handling gas or fuel lines can lead to carbon monoxide poisoning, fires, or explosions. Leave the tools to our fully certified professionals!
While you should always book your annual service, sometimes your heating system will cry out for help before your 12 months are up.
Get in touch immediately if you notice:
Frequent drops in boiler pressure (meaning you constantly have to top it up).
Strange, loud noises coming from the boiler casing or radiators (banging, whistling, or kettling).
Water leaking or dripping from beneath the boiler unit.
Your hot water or heating is taking much longer to heat up than usual.
