What Boiler Servicing includes?
Here's what's included in a standard annual gas boiler service, carried out by a Gas Safe registered engineer:
- Visual inspection — boiler casing, pipework, and flue checked for damage, corrosion, or leaks
- Internal components — burner, heat exchanger, and ignition parts inspected and cleaned
- Gas pressure & flow — tested and adjusted to manufacturer specifications
- Flue inspection — checked to ensure harmful gases are safely expelled outside
- Combustion analysis — flue gases measured to verify safe, efficient burning
- Magnetic filter clean-out — removes built-up metallic sludge captured from radiators and pipework
- Condensate trap clean — debris cleared from the condensate system on condensing boilers
- Safety devices — pressure relief valves, thermostats, and sensors all tested
- Controls check — thermostat, timers, and smart controls confirmed working
- Water pressure — verified within safe range (around 1 bar)
- Electrical connections — wiring and seals inspected for security
- Service certificate — signed record issued for warranty or landlord compliance
In Depth Boiler Servicing
Every 3–4 years, a boiler should have a more thorough "deep service" that goes beyond the standard annual checks.
What a deep service includes additionally:
- Chemical inhibitor replacement — corrosion-preventing fluid degrades over time and needs refreshing
- System flush — clears sludge, limescale, and debris from the boiler, radiators, and pipework
- Expansion vessel recharge — loses pressure charge over time; checked and recharged as needed
- Pressure relief valve inspection — examined for wear and replaced if deteriorating
- Circulation pump check — inspected for wear or reduced flow
- System water quality test — checks suspended material in heating water to assess if a full flush is needed
- Heat exchanger deep clean — thorough descaling, especially important in hard water areas
Benefits to a boiler service
Regular boiler servicing comes with a range of important benefits for your heating system.
Energy Efficiency
Improves energy efficiency and helps reduce heating costs.
Less Breakdowns
Lowers the chance of unexpected breakdowns and costly repairs.
Long Lifespan
Extends the lifespan of your boiler with regular maintenance checks.
Safe Operation
Ensures safe operation by identifying issues before they develop.
Valid Warranty
Helps keep your manufacturer warranty valid and fully protected
Landlord Safety Certificate
A Landlord Safety Certificate (CP12) is a legal requirement for rented properties, confirming that gas appliances, pipework, and flues have been checked by a Gas Safe registered engineer and are safe to use.
It must be renewed every 12 months and helps landlords stay compliant while protecting tenants. Our engineers carry out full inspections and issue the required certification for complete peace of mind.

FAQs about boiler servicing
Got questions about boiler servicing? We've answered the most common ones below. If you don't find what you're looking for, feel free to get in touch with our team.
Once a year, without fail. An annual service is the single most effective thing you can do to keep your boiler running safely and reliably. It keeps the manufacturer warranty valid, helps the boiler run at peak efficiency, and gives you peace of mind heading into the colder months. Most engineers recommend booking in late summer or early autumn before the winter rush.
For homeowners it is not a legal requirement, but it is strongly recommended. For landlords it is a different story — you are legally required to have all gas appliances checked every 12 months by a Gas Safe registered engineer and provide tenants with a valid Gas Safety Record. Failing to do so can result in serious penalties.
A standard boiler service takes around 45–60 minutes. If the boiler hasn't been serviced for a number of years, or if the engineer identifies issues that need closer attention, it may take a little longer. It is a relatively straightforward visit and causes minimal disruption to your day.
Skipping a boiler service might not cause an immediate problem, but the risks can build up significantly over time. Regular servicing helps keep your heating system safe, efficient, and reliable, while neglecting maintenance can lead to a range of avoidable issues, including:
- Your manufacturer’s warranty may be invalidated if annual servicing requirements are not met.
- Boiler efficiency can gradually decline, causing higher gas consumption and increased energy bills.
- Minor faults and worn components may go unnoticed, eventually developing into expensive repairs or complete boiler breakdowns.
- The lifespan of your boiler can be reduced, meaning you may need a replacement sooner than expected.
- Heating performance may suffer, resulting in inconsistent temperatures and reduced comfort throughout your home.
- Safety risks increase, including the possibility of gas leaks, carbon monoxide leaks, or other potentially dangerous faults.
- Unexpected breakdowns are more likely, particularly during the colder months when your heating system is under the greatest strain.
An annual boiler service provides peace of mind that your appliance is operating safely, efficiently, and in line with the manufacturer’s recommendations.
Yes, slightly. The core safety checks are the same across all types, but the specifics differ depending on your system:
- Combi boilers — the most common type in UK homes. The service covers both the heating and hot water functions in one unit, including the diverter valve, plate heat exchanger, and expansion vessel. There is no separate hot water cylinder to check.
- System boilers — these work alongside a separate hot water cylinder. The engineer will check the cylinder, its thermostat, and the motorised valves in addition to the boiler itself.
- Regular (conventional) boilers — the most complex setup, with a cylinder and a cold water tank usually in the loft. The service covers the boiler, cylinder, tank, and all associated controls and valves. These services can take a little longer due to the additional components.
A little preparation goes a long way and helps the visit run smoothly:
- Make sure the boiler is accessible — clear any boxes, coats, or clutter stored in front of or around the boiler cupboard
- If your boiler is in a loft or awkward space, ensure there is safe access
- Have any previous service records or paperwork to hand — these help the engineer spot any recurring issues
- Make a note of anything unusual you have noticed, such as strange noises, pressure drops, or slow heating
- Ensure someone over 18 is home for the duration of the visit
Only a Gas Safe registered engineer is legally permitted to work on a gas boiler in the UK. Always ask to see the engineer's Gas Safe ID card before work begins. You can also verify any engineer's registration at the Gas Safe Register website.
A one-off annual service typically costs between £80–£120, depending on your location, boiler type, and the engineer. Some homeowners opt for a boiler cover plan which spreads the cost monthly and often includes breakdown cover alongside the annual service.
Yes. Most manufacturers including Worcester Bosch, Vaillant, Baxi, and Viessmann require proof of annual servicing by a Gas Safe registered engineer to keep the warranty valid. Miss a year and you could find yourself without cover when you need it most.
Don't wait if you notice any of the following:
- Unusual noises such as banging, kettling, whistling, or gurgling sounds coming from the boiler or pipework
- The boiler losing pressure repeatedly, even after it has been topped up
- A yellow or orange flame instead of a strong blue flame (where visible), which could indicate a combustion issue
- Higher-than-normal gas bills without any obvious increase in heating or hot water usage
- The boiler cutting out unexpectedly or taking longer than usual to heat your home or provide hot water
- Radiators that remain cold in places or take much longer than normal to warm up
- Any leaks, drips, or signs of water around the boiler or associated pipework
- Error codes appearing on the boiler display or warning lights that persist after a reset
