A Quick & Simple Guide to Annual Gas Boiler Servicing

It is necessary to possess your boiler serviced every year to make sure that it continues to work safely and effectively.


It’s important to create sure it works properly year after year after you 

depend upon your boiler to produce you with enough heating and plight. It’d help to stay it running properly and ensuring it’s safe to use by hiring

 a  licensed engineer to try and do an annual work on your boiler.

What’s Boiler Maintenance?

Boiler service means having the boiler to be inspected by a trained heating specialist to confirm that it works safely and efficiently. 

The engineer will conduct a series of tests to determine if your boiler has any defects or 

complications that would endanger the security of you and your house.

Checklist for Normal Boiler Repair

It’s the little things that matter when it involves boiler repair.

Although most people believe boiler maintenance is once a month or twice 

a year, to urge the foremost out of your appliances, 

you ought to use the regular boiler maintenance checklist daily.

  • Inspect the boiler machinery for leaked water around and beneath
  • Ensure that the realm surrounding the boiler is clean and free from materials that will create an obstruction.
  • If appropriate, carefully wait for any error codes or service codes on the computer screen.
  • If any error codes are noted, jot them down and send them to the service provider.
  • Making sure the termination of the vent isn’t obstructed by debris, ice, or snow, or obscured.
  • Inspect the opening of the combustion air for blockages.
  • Often listen carefully to the devices for any unexpected sounds or disturbances.

Boiler Checklist for Monthly Inspection

You should perform a more thorough inspection once a month, additionally to the regular boiler repair checklist. Make certain to after the monthly  inspection:

  • For any symptoms of leaking, corrosion, or indicators of blockage,  visually check the combustion air piping and flue gas vent piping.
  • For any obvious signs of leaking or moaning, inspect the escape valve discharge tubing and boiler regulator.
  • If the machine may be a condensing boiler, inspect the condensate drain line, PVC fittings, drain system, and drain trap for any kinds of blockages

Get the boiler serviced regularly

Every year it has to be serviced professionally to stay the boiler running at

 its best, stop breakdowns, maximize its longevity, keep heating bills down,

 and ensure it’s covered by the manufacturer’s warranties. A Gas Safe engineer who can ensure all the weather is in safe working order and detect minor faults before they transform 

uncomfortable and expensive breakdowns must do that.

Verify the pressure of the boiler

The boiler has got to be set at the proper pressure to be ready to pump plight round the pipes and radiators in your building. In keeping with the manufacturer’s consumer directions, you’ll be able to review the pressure gage to form sure it functions to the proper standard. Typically, it’s between 1 and a couple of bars. You may change this on your own if the pressure is simply too low or too high.

To ensure that it works safely and runs successfully, it’s important to own the boiler serviced regularly.

An engineer will visit your home during a boiler operation and execute a group of safety and quality control on your heating system, so what exactly does it involve?

We will also put you in contact with up to three trained and trusted engineers in your region who will provide your boiler service with free, no-obligation quotes so that you’ll compare rates and choose the simplest.

Why Boiler Operation Matters?

Here are just some reasons why the boiler should be serviced annually:

Safety

A boiler service helps the engineer to detect safety hazards like a spill of carbon monoxide gas.

Carbon monoxide is an odourless and colourless substance that will cause brain injury and, in some circumstances, death instantly. For eg, if you’re worried that your boiler won’t be running properly, the flame is orange instead of blue, whether or not your annual service isn’t yet due, you’ll call a Gas Safe engineer.

Hold Low Heating Bills

It will dwindle effective as a boiler era, which suggests it has to use more fuel to heat your house, which can cost you additional cash. An annual service would make sure that all the parts are within the highest possible shape and for extended to attain a higher degree of performance.

Avoiding breakdowns

In the expectation of saving yourself a small amount of cash, it should be tempting to place off having your boiler serviced, but within the future, a boiler service can help keep your electricity costs down and even find a possible failure before it occurs, saving you from a boiler malfunction and an important maintenance bill.

Guarantee

A manufacturer’s warranty lasting between 1-15 years will usually be given your boiler, which ensures that any defects that occur during that period are going to be fixed free from charge.
This warranty, though, is just true as long as you’ve got a Gas Safe engineer repairing the boiler every year.

Boiler quality comprehension

Let’s explore reliability before we get into boiler repairs. Within the fresh air, boilers draw it, heat it, and send the stack down. The littlest quantity of flue gas (exhaust gas that’s expelled) at all-time low possible temperature are produced under optimal conditions.

In cold water, the boiler system takes it in, heats it to steam, and uses the warmth.

Using energy-

efficient appliances are one of the simplest ways for an organization to cut back running costs. To assist make your boiler system more practical and economize on your monthly bills, here are some fast tips:

  • Get an economizer installed.
  • Mount a Drive for Variable Frequency.
  • Preheat air for combustion.
  • Move the condensate back to the boiler.
  • Blowdown Rate Management.
  • Steam Traps survey.
  • Regularly turning the burner for seasonal adjustments
  • Reset outdoor temperatures and set back nights (hydronic boilers)

How does boiler feedwater output impact my boiler’s operation?

There are impurities and gases in low-quality boiler feedwater that may contribute to reduced performance and boiler or machine leaks.
In taste, scent, and colour, plain water is neutral. While this is often suitable due to its easy boiling point and steam generation for the transport of energy, it’s costly to provide. You’re likely to encounter suspended and liquid solids in wells and municipal sewage, furthermore as dissolved gases.  Industrial pollutants, sediments, and microorganisms might also contain feedwater.

Weak water treatment will have various consequences on your boiler operations:

Oxygen pits and spills are caused by dissolved oxygen.
Dissolved CO2 that travels with the steam out of the boiler may make condensate acidic. Your piping will corrode this acid condensate by applying iron to your boiler water furthermore. Dissolved solids in feedwater pipes, economizers, and boilers can cause the size to shape. This size prohibits metal heat-absorbing surfaces from being cooled by boiler water.

 The boiler will produce tube roll leaks, hot spots, and at last, a pressure element breakdown because the problem worsens.
The high concentration of the conventional impurities of the furnace,  the over-treatment of chemicals, or the unintended application of organic matter (grease or oil) ends up 

in the foaming of the carry-over. This drives the froth out of the steam outlet of the boiler which can have significant effects. When this happens, loud noise during a steam pipe,  corrosion in steam pipes, and boiler tide accidents are all likely.

With my condensing furnace, what could go wrong?

The most famous form of the new boiler is condensing boilers. They’re a godsend to households fighting higher costs of gas and electricity but may require boiler servicing more frequently. The good news is that 10- 20 percent simpler than regular boilers are condensing 

boilers. However, the bad news is that in cold temperatures, the system is more likely to freeze up. For this reason, regular gas boiler maintenance is very important. If the skin temperature is below freezing and your condensing boiler isn’t working, or a slip-up is shown, your condensate pipe can be frozen.

Why a Boiler Service?

Your boiler works hard to supply your home warmth and plight, and it needs a small amount of affection and a focus now and so, like most things. Not only will the engineer give your boiler the care it needs once you book an annual service, but they will also detect and fix any minor faults before they transform major problems. You’ll be able to shorten its life if you do not do right by your boiler and face costly repair bills along the way.

A regular boiler service can help to minimise the danger of highly hazardous and potentially life-threatening carbon monoxide gas poisoning. You will not be ready to tell if it’s leaking from your boiler because CO may be a scentless gas, but a Gas Safe engineer will jazz.

It will also help to optimise performance and efficiency so you’ll be able to 

cut your carbon footprint and keep saving money on your energy bills by getting your boiler serviced per annum.
Having an annual boiler service may be a requirement of your insurer in

many instances and a condition of the guarantee of your manufacturer likewise.

What Includes in a very Boiler Service?

During your boiler service, a professional Gas Safe engineer has the talents and expertise needed to conduct different tests and identify any leaks, 

corrosion and repairs. If necessary, they ought to also clean any parts and provides you advice on 

how best to seem after your boiler. The engineer will offer you a written 

service report once the service is complete, detailing what they need to be 

done to your boiler. The report also will include information, together with the price of any repairs, about any parts which will have to be repaired or replaced. Your engineer should spend a minimum of half-hour servicing your boiler, so from the instant, they get to figure, make sure to time them. For a one-off service, the standard cost is between £75 and £100, which has both labor and call-out charges. 

Remember to test whether your boiler continues to be under the manufacturer’s warranty or is roofed by your home insurance if you would like to procure repairs.

Do I get a boiler service certificate afterward?

Once your Gas Safe engineer is finished servicing your boiler, you can ask them to provide a summary of the service. It’s not a legal requirement but it is good practice.

You can usually expect it to include details on:

  • which parts of the boiler have been checked or tested
  • any problems that have arisen,
  • any advised works that have been recommended

If you are a landlord you will legally require a more formal summary, commonly known as a Gas Safety Record to prove you’ve had an inspection carried out. The Gas Safety Record is also commonly referred to as a Gas Safety Certificate or a CP12 and is a standardised form that engineers need to fill out for customers who are legally required to have a boiler inspection.

Homeowners – a Gas Safety Record is not a legal requirement, but you can ask for one for your own records or to prove to future buyers that you’ve kept your boiler in good condition.

Landlords – it’s a legal requirement to get the boiler inspected annually, along with all other gas installations and appliances owned by you in your properties (you don’t need to be concerned with appliances owned by your tenant but most engineers will give these a visual inspection and make a record of the inspection anyway). You’ll need a Gas Safety Record as proof of this, which you can provide for your tenant every 12 months.

Tenants – your landlord will need to provide you with a Gas Safety Record within 28 days of the boiler inspection.

Are boiler service plans worth it?

Boiler service plans, also known as boiler cover, can help offer peace of mind in the case of any problems occurring with your boiler. In most cases, in return for a monthly fee, you’ll be assured that an engineer will be sent out to you to get your boiler back up and running.

https://www.npower.com/help-and-support/guides/boiler-servicing/

How much does a boiler service cost vs. a boiler service plan?

According to Which? the cost of a one-off boiler service is £72. But the cost can vary depending on where you live, the type of boiler service you pay for and which firm does the service. So the real cost of a one-off service might be anywhere between £70 and £135.

Compare that to the cost of a boiler service plan, which can be anything from £8.50 for a basic boiler care plan to £24 a month including your heating, plumbing and electrics too[14]. This works out at £102 a year for the cheapest cover. And £288 a year for the most extensive insurance policy.

Both types of boiler service plan work out more expensive. But you do get peace of mind that should anything go wrong, an engineer will be round to fix it – you’re not just paying for an annual boiler service. And with the average cost of a repair coming in at £270, you may be better off with boiler cover.

If you decide you want the security that a boiler service plan gives you, there are three things you should do:

  • Shop around for the best deal;
  • Read the small print on any policy;
  • Check out customer testimonials for any providers.

Can I get a boiler service through my home insurance?

You may be able to get a boiler service as part of your home insurance – but it’s unlikely. Usually, this is only included if you pay for an add-on service or take out supplementary cover, like a home emergency insurance plan. Most insurers exclude boiler cover from their home insurance policies, as things can go wrong all too easily

Signs that you need a boiler service now

Whilst you may have a routine annual boiler service scheduled if you see any of the following signs it is recommended that you get your boiler serviced as soon as possible:

  • You are not sure the gas appliance is working properly
  • The appliance appears to be burning with a lazy yellow flame rather than a crisp blue one
  • You can see black marks/stains around the gas appliance
  • You notice increased condensation in the room

Save energy in your home

As well as checking the physical aspects of your boiler, hot water and central heating system; many gas service companies will also be happy to advise you on how to save energy in your home as part of the annual service. 

This may range from adjusting the settings on your system for optimum efficiency and effectiveness, as well as practical changes you can make that may save energy and help to reduce your bills. A boiler health check is also often included, which can help you to know whether or not it is time to begin planning for a new boiler.

https://www.viessmann.co.uk/heating-advice/boiler-service-guide-for-homeowners

Additional services you’ll want from your boiler service

  • A visual inspection of crucial parts in the boiler (i.e. removing the case and checking the pump, heat exchanger, burner and ignition). This is to check to wear and tear but also to check all parts meet minimum safety standards set by Gas Safe.
  • Where necessary, remove dirt and debris (usually from the flue to ensure there is plenty of ventilation.)
  • Check the boiler is operating at the correct pressure.
  • Use a Gas Analyser to inspect the gases being released from the flue and ensure they are within tolerance.

Minimum expectations from a boiler service

Depending on if you are a homeowner/landlord, you’ll expect this as a minimum on your certificate:

  • Details of any flue or appliance that has been inspected.
  • Details of the engineer (Gas Safe number, signature and name).
  • Homeowners address/Landlord’s name and address (sometimes, the agent’s name and address is used).
  • Any issue relating to gas safety and what type of action has or needs to be taken to fix the problem.
  • Test results for any appliance or flue tested. Flues will be tested with flue gas analysers and some will be able to print out results on site.
  • Any safety defect identified and any action required or taken to rectify it
  • Confirmation of the results of the operational safety checks carried out on the appliances.

Paying for boiler servicing Before paying for repairs, check whether your boiler is still under its initial warranty. Most new boilers typically come with cover for parts and labour in the first one or two years. Some home insurance also gives you cover for boiler breakdowns, either as standard or as an optional extra, so it’s worth checking if you already have this. The cost of adding breakdown cover to insurance cover is usually much less than getting a breakdown contract, but you don’t get the same benefits. You’ll probably save money if you pay for services and repairs as you go along, rather than take out a boiler servicing contract – where you pay a monthly fee that also covers repairs. Our analysis shows that for more than nine out of ten Which? members this was more expensive than paying for one-offs. 

Things to consider and watch out for Ask what will be included in the boiler service. Watch the engineer and use our checklist to ensure that they cover the basics. A good boiler service should last at least 30 minutes. If it’s shorter than this, ask why.  Finally, ask for a written report and check it is accurately filled out. If you have any concerns, contact the Gas Safe Register on 0800 408 5500 or at gassaferegister.co.uk. It’s also worth getting a carbon monoxide detector. Although the checklist should stand you in good stead for most boilers, bear in mind that not all boilers are the same. Most older conventional systems, for example, have parts such as the heat exchanger, burner and fan that would need to be dismantled and checked. This is not normally necessary for a modern boiler unless the flue gas analysis suggests there’s a problem.

Preventative maintenance checks

You can do your checks throughout the year to ensure the system is well maintained:

Tank checks to avoid water ingress to the tank:

  • Check there are no signs of corrosion on a metal tank or bulging on a plastic tank
  • Check for leaks and physical damage
  • Cut back any over-hanging trees that will continue to drip water onto the tank
  • Check pipe joints
  • Check for corroded seals around lids and hatches
  • Check lids and caps are secure
  • Check for water in the summer months that may build-up due to condensation

Checking for water ingress:

  • Use a garden cane or any long stick
  • Coat in ‘water finding paste’ (available online)
  • Dip into the tank to the bottom
  • Wait the period given on the instructions and pull out
  • Check the colour against the chart to see if the water is present
  • Checking/preventing oil leaks
  • Visual check tank for leaks and physical damage
  • Check all of the visible oil lines for leaks
  • Fit a Watchman or similar to monitor for any sudden drops in oil which may be the result of a leak

Boiler checks and cleaning

The boiler works properly and efficiency when it burns the oil cleanly. When the boiler can achieve what engineers refer to as ‘complete combustion’, the boiler will extract get the most energy from the fuel. If the burner, fan, baffles or tabulators are dirty and sooted then ‘incomplete combustion’ will occur, which means not all of the energy from the fuel is transferred to your heating system. This leads to waste fuel products – soot – building up inside the boiler and reducing the efficiency further.

  • Check combustion chamber rope seal
  • Remove the burner and fan and clean
  • Clean and descale baffles
  • Clean and descale the primary heat exchanger
  • Remove, clean and replace turbulators
  • Check combustion levels after cleaning

Tank and system checks

  • Inspect and clean condensate
  • Test the fire valve
  • Clean the condense trap
  • Clean or replace the filter
  • Carry out a visual inspection of the tank and oil supply pipe to check for damage, deterioration and debris
  • Pressure test the oil supply pipe where it runs underground
  • Check system pressure

Working with a quality engineer 

When having your boiler serviced, it’s essential to work with specialists in the field of heating and gas engineering. Your boiler is a complex piece of equipment so working with subpar contractors can lead to more problems than you started with. Therefore, there are a few checks you can make when looking to invest in a quality service.

For starters, it’s good to check that your engineer is, at the minimum, on the Gas Safe register. Gas and heating engineers need to be on the Gas Safe register by law in order to legally operate and repair your boiler. You can check to see if your engineer is on the register by checking the Gas Safe website, however, you can also ask to check an engineers gas safety certificate to give you extra piece of mind. Some engineers will also have other qualifications that can give you a better understanding of their quality, such as a City and Guild certificate or a relevant NVQ.

Another way to verify you’re working with a professional is to spend some time checking reviews from previous customers. Websites such as Feefo and Which’s Trusted Traders reviews are some of the larger trades review sites. Get an understanding of a companies previous work by looking at these websites to see if you’re going to be getting a quality job done.

Finally, check to see what your chosen engineer can offer you aside from a boiler servicing. A quality engineer can offer a range of services and will have the skills for boiler installation, central heating repairs and a host of others. So working with someone that can cover all bases can be a real help when it comes to keeping your heating in good nick.

Checklist for Boiler Service



First and foremost, it’s important to test that your engineer is approved by the Gas Safe Register, as this confirms that your boiler is legally allowed to be serviced. After they are servicing your boiler, you’ll also see your engineer to present you peace of mind that they need to be covered all the fundamentals. The subsequent should be done by a licensed boiler service engineer:


  • Conduct a visible inspection of the flame and boiler
  • Verify the input of force per unit area or heat
  • Don’t be scared to challenge them if the engineer takes but half-hour repairing your boiler or doesn’t do all of the things we’ve got included within the checklist. 
  • Alternatively, if you have got any doubts or complaints about the technician, you ought to contact the Gas Safe Registry.
  • Always compare prices for boiler operation
  • We suggest that you just have a minimum of three quotes so that boiler service prices are compared and therefore the best price are often found.
  • Depending on the sort of boiler you have got and who you would like to try and do the duty, a one-off boiler service will cost anywhere from £75 to £100. 
  • Local experts and corporations tend to be more competitive, but you’ll still compare national companies’ quotes. 
  • You need to also make sure that you’re employed with professionally trained engineers specified on the Gas Safe Registry, as this ensures that your boiler is lawfully allowed to be serviced.
