When is a boiler problem an emergency?
Wondering whether you need an emergency boiler repair in London? Think the problem can wait? If your boiler leaves you without heating or hot water, or where there is the potential for harm such as a gas leak, you need professional help, quickly.
Homeowners, tenants, children and the elderly can all be harmed if a boiler develops significant faults; professional remediation isn’t just advised, it becomes essential.
If your boiler won’t fire up, drips water, shows an error code that won’t clear or has a persistently dropping pressure gauge, call us.
If you smell gas, treat it as an emergency and act first; call us second. A gas leak or carbon monoxide risk is dangerous:
- Open doors and windows to ventilate the property
- Turn the gas off at the mains if it is safe to do so
- Do NOT turn any electrical appliances on or off and avoid naked flames
- Leave the property if the smell is strong
- Call the National Gas Emergency Service on 0800 111 999 (24hrs)
Carbon monoxide is harder to spot. Warning signs include headaches, dizziness, nausea and a lazy yellow or orange boiler flame rather than a blue one. Treat it the same way as a gas leak and call the emergency line.
Once the immediate danger is dealt with, call us, and we’ll dispatch a Gas Safe engineer to you as fast as possible.

Our Happy Clients

How much does an emergency boiler repair cost in London?
We remain fully transparent at all times. No hidden charges or surprise fees. However, the cost for emergency boiler repairs in London varies. It will depend on the type of fault, the parts required and the time of the callout. Simple fixes, such as replacing minor parts or clearing a frozen pipe, can be quick and very low cost. A major fault or a boiler replacement will take significantly longer, and naturally, be more expensive.
At London Property Services, we are honest and upfront. The price you are quoted is the price you pay, unless further faults are discovered which require additional work. No matter what, you always remain fully informed of timelines, costs and the work we are undertaking.
Is it worth repairing or replacing your boiler?
Once our boiler engineer has diagnosed the fault, they’ll tell you honestly whether a repair makes sense or whether a replacement is better value. As a rough guide, most boilers last around 10 to 15 years. A one-off fault on a new boiler is almost always worth repairing.
Replacement may be the better option if your boiler is more than a decade old, breaks down repeatedly, needs an expensive part or is an inefficient model that keeps pushing your bills higher. We won’t push you towards a new boiler you don’t need; you’ll be given an honest assessment, meaning the decision to repair or replace remains yours.


Will my insurance cover emergency boiler repair?
It depends on your cover. Standard buildings and contents insurance does not usually cover a boiler breakdown when it’s due to age or wear. They are among the most common reasons claims are denied.
You may be covered if you have:
- Boiler cover or a home emergency policy
- A manufacturer’s warranty
- Landlord home emergency cover for a let property
You are less likely to be covered for:
- General wear and tear
- A boiler that hasn’t been serviced or maintained
- Pre-existing faults
If you think you are covered, check your policy or contact your provider before booking and keep any paperwork or receipts.
What to do if your boiler breaks down
Before you call, a few quick checks sometimes get you going again, and if not, they help us arrive with exactly what we need to get your boiler working again.
- Check the basics: Is your thermostat set high enough and is the boiler’s power supply on? They sound obvious but are among common causes for a boiler “not working”.
- Check the pressure gauge: If it is below the normal band (1-1.5 bar when cold), the low pressure may be stopping the boiler from firing. (Your user manual should indicate how to repressurise the boiler)
- Look for a reset button: Many boilers show a fault or lockout light with a reset. One reset is worth trying, but if you are doing it multiple times with no change, there is a fault that needs investigating.
- If you smell gas: Stop, ventilate, shut off the gas, don’t turn anything electrical on or off, call 0800 111 999.
- If water is leaking: Turn off the boiler, and if you can, shut off the water supply to limit any further damage.
- Call us on 020 7186 0270: Tell us the make and model of your boiler if you can, and any error codes it may be displaying.



Which boilers do you repair?
Our Gas Safe Engineers work on all the main domestic and commercial boiler types. When you call, telling us the type of boiler you have can ensure we enter the property with as much information as possible and work on your boiler much faster.
- Combi boilers: The most common boilers in London homes, heat water on demand with no separate cylinder.
- System boilers: Work with a hot water cylinder, common in larger homes.
- Conventional (regular/heat-only) boilers: Work with both a cylinder and tank, typically found in older London properties.
Brands we work with
Our emergency boiler repair specialists are experienced in working with a wide range of boilers from all leading brands. These include Worcester Bosch, Vaillant, Potterton, Alpha, Ariston, Baxi and more.
Unsure on the make or model of your boiler? Don’t worry, our team is suitably qualified and experienced to work on your boiler regardless of make and model.

Fully trained and certified in both electric and wet heating systems, our team diagnoses the fault carefully before safely repairing your boiler. If you are a landlord or letting agent with a tenant who has no heating or hot water (something you are legally obligated to provide them with), a quick call to us gets your emergency boiler repair in London prioritised.


Commercial emergency boiler repair
A boiler failure in a commercial property can harm productivity, impact customer experience and make the premises uncomfortable to work in or visit. Our boiler repair engineers attend your property as quickly as possible, causing minimum disruption whilst detecting the fault and restoring the heating and hot water.
We attend any business property across London, and our out-of-hours emergency boiler repairs in London can be conducted at a time that suits you to ensure customers and staff are not impacted by our presence. For managing agents, facilities teams and landlords, we can invoice and coordinate access to suit your processes.
Landlord gas safety: Your legal obligations
If you are a landlord, you have a legal duty to keep gas appliances safe. Under the Gas Safety (Installation and Use) Regulations 1998, you must arrange an annual gas safety check on every gas appliance and flue in your rental property.
You must also:
- Provide tenants with a copy of the Gas Safety Record within 28 days of the check and to new tenants before they move in.
- Keep records for at least two years
- Ensure any appliance found unsafe is repaired, made safe or replaced before it is used again.
An emergency boiler fault in a let property can leave you exposed to your repairing obligations, so a fast, certified repair matters. As Gas Safe registered engineers, we can attend the emergency, carry out repairs and arrange your annual gas safety checks and certificates to keep the property compliant.
