Most of us only think about the boiler when it stops working. By then the house is cold, and the repair feels urgent. A yearly service helps you avoid that, and it is also a safety job.
First, this guide explains what the Health and Safety Executive (HSE) advises. Next, it covers what Gas Safe registration means and how to check the person at your door.
How often should a boiler be serviced?
The HSE says gas appliances, flues and pipework should be installed, regularly maintained and serviced at least annually. It also says appliances should be checked for safety at least once every 12 months. In other words, a yearly visit is the standard to aim for.
Many people leave it until winter. However, a breakdown hurts most in the cold months. Therefore, booking early in the year is a sensible habit, because you pick a date that suits you.
Why the service matters for safety
A gas boiler burns fuel to heat your home. If it is not working properly, dangerous levels of carbon monoxide can build up. The HSE notes this can happen when ventilation and flues are not working as they should.
For that reason, a regular check by a trained engineer matters. You should not wait for a problem to show itself. Our boiler service visits are aimed at exactly this kind of problem.
Fit a carbon monoxide alarm
The HSE strongly recommends carbon monoxide alarms as an early warning. However, it is clear that an alarm is not a replacement for regular maintenance and safety checks by a registered engineer. Think of the alarm as a back-up, not a substitute.
Test the alarm as the maker advises. For example, pick a fixed date each year, so you do not forget. If it sounds, take it seriously. Then have the appliance looked at by a registered engineer.
Only a Gas Safe registered engineer can do the work
The HSE states that anyone doing domestic gas work must be on the Gas Safe Register. This is not a matter of personal preference. Instead, it is the rule for anyone who works on your gas appliances.
The HSE also says it is illegal for anyone to use a gas appliance if they suspect it is unsafe. As a result, if you think your boiler is faulty, turn it off and leave it alone. Wait until a Gas Safe registered engineer has checked it.
How to check an engineer
Every registered engineer carries a Gas Safe ID card. The HSE says the card tells you which appliances the engineer is qualified to work on. Ask to see it before any work begins.
You can then check the engineer in three ways. First, use the Find an Engineer or Check an Engineer pages on the Gas Safe Register website. Second, ring the Gas Safe Register if you are in any doubt. Third, text the word Gas and the engineer’s seven-digit licence number to the Gas Safe Register’s text service.
Look closely at the card, not just the name. The HSE also notes the card lists the work the engineer is registered for. For example, a registered engineer may be qualified for some appliances and not others. Make sure the card covers boilers if that is the work you need.
What to expect on the day
A good engineer will show their card, explain the work and answer your questions. They should also tell you plainly if they find a fault. In addition, they should explain any next step in words you understand. Afterwards, keep any paperwork you receive, so you have a record of the visit.
If something needs repair, ask what the fault is, why it matters and what your options are. For repairs, our gas engineer team covers Warrington and nearby towns such as Lymm, Frodsham, Runcorn and Widnes. You can also use our online quote form to describe the job.
If you smell gas or suspect a leak
Follow the HSE steps for a suspected gas leak. Call the National Gas Emergency Freephone number, which is run by National Grid. Open all doors and windows, and shut off the gas supply at the meter control valve if you know where it is.
Do not use the appliance again until a Gas Safe registered engineer has checked it. Because gas problems can become dangerous quickly, never wait to see whether it clears. Meanwhile, keep the doors and windows open.
Landlords and tenants
If you rent your home, the picture is a little different. The landlord must arrange the annual gas safety check for the gas appliances they provide, and the engineer must be Gas Safe registered. Our landlord CP12 service covers this paperwork for landlords.
Tenants who are unsure should ask the landlord for the latest record. However, a tenant who suspects a fault should not use the appliance. They should report it straight away.
A simple yearly routine
Keep the routine short and repeatable. As a result, it becomes a habit rather than a chore.
- Book the service at the same time each year.
- Ask to see the Gas Safe ID card first.
- Check that the card covers boilers.
- Keep your service record somewhere safe.
- Test your carbon monoxide alarm.
Finally, remember that a planned visit is easier than an emergency. A calm appointment means fewer surprises when the cold arrives.
