What Does It Mean That Your Boiler’s Been Condemned?
It means an engineer or boiler safety inspector has conducted a safety check and your boiler doesn’t meet current codes of practice. It also means your boiler could be dangerous or is not combusting properly, which can lead to fumes and emissions floating about in your house.
Don’t Panic
But don’t panic. Boiler safety is a primary concern for engineers. So, if an engineer has deemed your boiler unfit, he or she will have switched it off and made it safe. We repeat, don’t panic.
What Next?
Now that your boiler is shut off, you’ll want to review the engineer’s notes and warning notice and ask whether or not you boiler is repairable or if it’s a good candidate for combi boiler replacement.
Consider a Second Opinion
If you’ve got the time and patience, it’s not a bad idea to get a second opinion. You could save yourself a lot of money and a lot of headache.
What Went Wrong?
Your boiler could be condemned for a number of reasons – some are more serious than others.
- It could be something as simple as inadequate ventilation, which is a quick fix.
- Or it could be something as serious as problems with the flue or combustion of the boiler which are very serious, and can lead to carbon monoxide seeping into your home.
*Boiler Safety Tip – Carbon monoxide is sometimes called the silent killer because it’s colorless and odorless. It can inflict serious harm ranging from a bad headache to death.
Pick Your Gas Safe Registered Engineer
Now that’s it’s been determined you’ll need to have your combi boiler replaced or serviced it’s time to contact a gas safe registered engineer to perform any service you’ll require and to ensure your boiler’s safety and proper installation.
Once you’ve selected an engineer to repair or replace your boiler be prepared to find out:
- How quickly they can complete the work?
- Have they encountered a problem similar to yours before?
- Are they familiar with your geographic area?
(If you can find an expert who’s worked in your area before, he’ll be familiar with any peculiarities specific to it. As a result he’ll be able to provide indicative costs and know exactly what needs to be done based on his experience.) - Always get a fixed price quotation. Don’t accept an estimate.
- Don’t pay cash and never pay anything up front. Most reputable companies have a 30-day credit limit with suppliers and don’t require an advance.
- Make sure you get everything in writing, so you your expectations are properly set.
- Don’t be rushed into something just because you have no heat or hot water. If you’re being rushed, it’s a tell-tale sign there’s some unscrupulousness on the other end of it. Don’t let yourself be taken advantage of!
- Make a solid purchase. Don’t always go for the cheapest boiler.
- When considering combi boiler replacement , if you’re overly concerned about cost, you run the risk of buying a boiler that won’t last as long and will be more expensive in the long run since you’ll need to replace it sooner.
(There are so many payment options available that you may be able to afford a better boiler than you think.) - Once you’ve had repairs performed or a new boiler installed, be sure to get a certificate stating that your boiler now meets current codes of practice, and meets all requirements for boiler safety.
If you’re a homeowner, sooner or later you’re going to be confronted with the reality of a condemned boiler and combi boiler replacement.
The good news is that if you have the right information and are prepared to ask the right questions, repairing or replacing your combi boiler doesn’t have to be a painful experience.
And getting the best combi boiler at a price you can afford can be as simple as making a few smart decisions.
IF YOU REMEMBER ONE THING FROM THIS ARTICLE!
Remember this … If you’re boiler is condemned, don’t panic. Take the time you need to make a smart decision, work with the right people and get a boiler that works best for you and your budget.
Remember, if you’re feeling pressured to make a decision, it means your heating engineer is thinking more about his best interests than yours. Take a pause and push back until you get what you need.

I’ve been told my boiler will be condemned if it’s serviced because it has a bit of glass broken off on the ‘window’. Is this right? If so, will have to risk never having it serviced again as can’t afford the £4k quoted to replace and relocate.
Hi,
A routine visit to provide a Landlord Safety Certificate resulted in the engineer finding raised CO levels. Without any further checks he “diagnosed” a faulty gas valve. The boiler is less than 3 years old (Potterton Precison). He did not switch off the boiler (other than the heating controller power) and did not cap off the boiler. He didn’t put a condemned sticker on the appliance and left no report of the work done or faults found. He works as a third party engineer for a National Emergency Care Plan provider with as it turns out a poor reputation.
Is this a safe or adequate service? Should I report the event in more detail?
Sorry I should add that I was so concerned about the national service care plan providers lamentable support, I tried to cancel the policy but they are insisting on my continuing with the policy.
I have now taken out a second policy with SSE. The engineer did the checks, diagnosed the same CO problem
He did metered flow checks which ruled out the possibility that it was simply a gas service valve issue.
He checked the flue seals and found those to be in good condition (the boiler is less than 3 years old)
He checked the heat exchanger and had concerns about its condition and feels sure that is the probable issue.
He has arranged a return visit tomorrow and all parts will be made available and the repair made.
I will not have to make any further payments other than the service plan monthly fee.
He capped off the boiler at the consumer meter to make the system safe, or would have made me sign paperwork saying I had refused.
He left a service sheet itemising actions and faults.
I presume that is what I should have received in the first instance from the dodgy provider?
