Your engineer shows their Gas Safe ID, then inspects the boiler, controls, pipework and flue for wear, leaks or corrosion.
We open the boiler, clean key components, run a flue gas analysis and check gas pressure and safety devices.
We complete your service record for your warranty and explain anything that needs attention, with a clear price before any extra work.
A boiler that has sat quietly through the summer is suddenly asked to run for hours every day once the cold sets in across Middlesbrough, Stockton and East Cleveland. That first long cold spell is when hidden problems show up. During Storm Boelo this October our emergency line was busy with boilers struggling under sustained use, and many breakdowns start as small faults that a routine service would pick up.
Most manufacturers also require an annual service by a Gas Safe registered engineer to keep your warranty valid, so a missed service can leave you paying for repairs that would otherwise be covered. Just as importantly, a service checks that your boiler is burning safely. A poorly maintained boiler can produce carbon monoxide, a poisonous gas you cannot see or smell, which is why we also recommend an audible carbon monoxide alarm in every home with a gas appliance.
Quick tip: the best time to book
Late summer and early autumn are the ideal time for a service, before the heating goes on full time. Call 07971 634609 to book a date that suits you.
Every service is carried out by a Gas Safe registered engineer and covers these key checks:
We check the boiler casing, seals, controls and pipework for signs of corrosion, leaks or damage, and make sure the boiler is installed and ventilated correctly.
Using a digital analyser, we measure the combustion gases to make sure your boiler is burning gas cleanly, safely and efficiently.
We test the working gas pressure and system pressure, and check that the safety valves and shut-off devices are working correctly.
We remove the casing to clean out dust and debris, inspect the main heat exchanger and burner, and clear the condensate trap where fitted.

Once every 12 months. Most manufacturers require an annual service to keep the warranty valid, and it is the best way to spot small faults before they turn into breakdowns.
Most boiler services take around 45 minutes to an hour, depending on the boiler and whether any parts need extra cleaning or replacing.
Yes. We complete the service record your manufacturer needs, so you have proof that your boiler has been serviced every year by a Gas Safe registered engineer.
No. A service cleans and checks the boiler so it runs safely and efficiently. A gas safety check (CP12) is a legal safety inspection landlords need every year for all gas appliances. We can often carry out both on the same visit.
We provide professional 24/7 plumbing services across Middlesbrough, Stockton, Guisborough, and Redcar.
