🚨 Smell Gas or Suspect a Leak? Do This Immediately
If you suspect a gas leak, you should not hesitate to take the necessary steps to stay safe, this includes:
Turn off your gas immediately.
Do not use any electrical switches, naked flames or smoke.
Leave the building and call the National Emergency Gas number: 0800 111 999.
Smell gas inside your home? Call 0800 111 999 immediately. It's better to be safe, than sorry.
Do You Actually Need an Emergency Boiler Installation?
After safety, the next thing to consider is whether or not you actually need an emergency boiler replacement or if you can wait.
There are many Gas Safe engineers that operate 24/7 and 365 days a year, but outside of their normal working hours, they do charge a premium for their services.
The exact price depends on the type of boiler installation, but in order to get your boiler fitted quickly and outside of normal hours, you can expect to pay between 20% to 40% more than the usual price.
Using a traditional, local engineer, expect to pay 20-40% more if you're in an emergency. Use Heatable, and you won't be charged an extra penny.
Typically, a boiler installer will be able to visit you and provide you with a quote the same day. However, it’s always advised to get quotes from at least 3 different companies, which may lead to further delays.
If you’re not willing to pay the additional emergency fees, you can expect a new boiler installation to be completed between 7 to 14 days of the job being confirmed. Alternatively, you can get a fixed price from us, you’ll even be able to view the calendar and check current installer availability.
We offer installations as quickly as tomorrow (UK-wide), which is the next best thing to an emergency boiler installation.

Repair or Replace? What to Consider
If your boiler is playing up again, chances are, it’s nearing the end of its life. Here’s how to know when replacement is the smarter move:Is your boiler out of warranty?
You may be thinking about whether it’s going to be cheaper to simply repair your boiler, rather than replace it, however, if it’s an emergency boiler installation you’re looking for, the likelihood is that you’ve got a pretty good idea of its current state.
If this isn’t the first time your boiler has broken down and it’s pretty old, then that’s a good indication that your boiler may be reaching the end of its life.
The following factors could mean that replacing your boiler will be more cost-effective:
The age of your boiler
Just like most things, boilers experience wear and tear to their internal components and given enough time, they will eventually break and need repairs or replacement.
In old boilers, these types of repair costs are more common and can soon rack up, making it far more cost-effective to simply replace your boiler with a new one.
Common part failures:
On average, the best combi boilers last around 10 years (that's a decade, to you and me), so if your boiler is getting on a bit, it’s a good indication that it might need to be replaced.
Repair costs
As mentioned, older boilers are much more likely to experience breakdowns due to part failures.
These parts can be expensive in any type of boiler but can be particularly costly in older boilers.
This is due to many older boilers no longer being in production, meaning parts can be more difficult to source.
Drops in efficiency
10+-year-old boilers are G-rated and only have an efficiency rating of around 70%. This means for every £1 spent, 30p is being totally wasted. Modern A-rated boilers (like the one's Heatable install), are 90%+ efficient.
💷 How Much Does an Emergency Boiler Installation Cost?
Just like a typical boiler installation, the final cost will vary and depend on a variety of factors, these include the following:
The type of boiler you have installed e.g. regular, combi or system.
The model you choose e.g. mid-range vs. premium.
If you want to move your boiler to a different location.
If you want to convert from one boiler type to another.
Any extras you purchase e.g. smart thermostats, premium magnetic filters etc.
For illustration, a straightforward combi swap (installing a new combi boiler in place of your current one) is going to be less expensive than converting from a different type of boiler to another e.g. from a combi to a system boiler.
The most common, emergency boiler replacement is a combi boiler replacement. It's much more straight forward, making it cheaper.
This is because these installations are more complex, requiring more time, more labour and typically more materials. More everything.
It also depends on the model of boiler you choose, we offer more value-orientated brands such as Alpha, as well as premium, award-winning boiler brands such as Worcester Bosch and Viessmann.
The good news is that we offer multiple ways to pay for your replacement boiler, including cash and pay monthly boilers on finance.

⏱ How Long Does Emergency Installation Take?
It’s important to consider how long your replacement boiler installation may take, as some are more complicated than others.
Here’s a rough guide...
Install Type | Time to Complete |
Emergency Combi Boiler Replacement | 1 Day |
Emergency Regular/System Boiler Replacement | 1 Day |
Emergency System Conversion | 1-2 Days |
Emergency Back Boiler Conversion | 1-2 Days |
