A boiler engineer is who you call when the heating or the hot water has stopped, or when the boiler is behaving in a way you don’t trust. This page is about a boiler breakdown and those call now signs, not about choosing a new boiler.
Call 07935 205813 if you need help today. Timms Gas Services is Gas Safe registered and open 24/7. We’ve been doing plumbing, heating and gas work for 17 years. You can receive a complimentary consultation, and the site talks about clear and upfront pricing without giving a figure here.
If an engineer later says a new boiler may be wiser, read signs you need a new boiler. That post covers replacement. This one covers getting someone out.
When a boiler needs an engineer
You need a boiler engineer when the appliance has stopped doing its job, or when something about it looks or smells wrong. Don’t take the casing off, because work on gas appliances must be done by a Gas Safe registered engineer. That’s the law in the UK, and you can check a registration on the Gas Safe Register website. Our boiler repair in Bishop’s Stortford page is the local place to start if the unit has already failed.
We’re open 24/7, so a fault at midnight gets the same phone line as a fault at noon.
Everyday signs something is wrong
These are the everyday signs that usually mean you should call rather than keep resetting the boiler and hoping it holds.
No heating is the obvious one. The thermostat is up, the timer is on, and the radiators stay cold. No hot water at the taps is the other common one, especially on a combination boiler that should heat water when you open a tap.
A boiler that locks out after a reset is another prompt to ring. The same lockout coming back the same day is a breakdown that needs an engineer, not another try before bed.
New noises matter too. Banging, whistling or gurgling that wasn’t there last week can point to a fault, air or debris in the system. They are not always an emergency, but they are a reason to get the appliance checked before the house goes cold.
Our plumbing, gas and heating page lists the wider work around pumps, radiators and controls if the fault turns out to sit outside the boiler itself.
Warning signs you should not ignore
Some signs should not wait until a weekday morning. Water dripping from the boiler, a damp patch on the casing, or a pressure gauge that keeps falling all point to a leak. Leave the casing in place and call.
A carbon monoxide alarm that sounds is also a reason to get everyone into fresh air and to follow official advice, then to have the appliances checked. The HSE domestic gas page explains why those faults are treated seriously.
Repeated breakdowns are a warning as well. If you’re resetting the boiler every evening, treat that as a boiler breakdown even if you still have a little heat. An engineer can say whether a repair will hold. If they later think the appliance has reached the end of the road, use the replacement signs post rather than this one.
What to do if you smell gas
A smell of gas is not a wait and see problem. Don’t call us first.
Leave the boiler alone and ring the national Gas Emergency number on 0800 111 999. Open doors and windows if it’s safe, avoid light switches and anything that could cause a spark, and follow official Gas Safe Register leak advice while you wait.
Once that service has made the property safe, you can call Timms Gas Services about the boiler or about gas leak detection. The emergency number comes first every time.
Key takeaways
Call an engineer when the heating or the hot water has stopped, when the boiler keeps locking out, or when you see a leak. Don’t open the casing.
A smell of gas goes to 0800 111 999 first. Timms Gas Services can take the repair call after that, any day, because we’re open 24/7.
This page is about getting help with a breakdown, and the separate post on signs you need a new boiler is about whether the appliance should be replaced.
When this guide is the wrong choice
This guide is the wrong choice if you already know you want a new boiler and you’re planning the install. Use preparing your home for a new boiler or the replacement signs post instead.
It’s also the wrong read if you only want a routine service and the boiler is running as it should. Book a service rather than treating this as an emergency.
If you’re trying to decide between a repair and a new unit after an engineer has already visited, repair or replace your boiler is the better guide.
Common questions
Can I reset my boiler myself?
The handbook that came with the boiler is the place to check what you can do yourself, and if the boiler keeps locking out, call an engineer. Don’t take the casing off. A smell of gas still goes to 0800 111 999 first.
How do I know an engineer is qualified?
Ask to see their Gas Safe Register ID and check the number on the Gas Safe Register website before work starts. Timms Gas Services is Gas Safe registered. The card should match the person at the door, and it should cover the type of work they intend to do on your appliance.
Is a noisy boiler dangerous?
Not always. New banging or whistling is a reason to get the boiler checked, but it is not automatically an emergency in the way a gas smell is. Call if the noise is new, if it comes with a loss of heat or hot water, or if you also see water where it should not be. An engineer can say what’s causing it once they’ve seen the appliance.
What if my boiler breaks down at night?
Call anyway, because we’re open 24/7, so a night time boiler breakdown uses the same number as a daytime one: 07935 205813. If you smell gas, use 0800 111 999 first and follow Gas Safe Register advice until that service arrives.
