-
🛠️ Plan for repairs or a replacement

🔧 How to Find Out Your Boiler’s Age
So, how do you actually figure it out? Great question! Let’s walk through it step-by-step:
1️⃣ Check the Serial Number 🧾
Most boilers have a label on the casing—often inside the front panel. The serial number is the key! 🗝️
Each manufacturer uses a different code, but here’s a quick cheat sheet:
| 🔥 Manufacturer | 🔍 How to Read It |
|---|---|
| Vaillant |
The serial number is typically a long number, 20 to 28 characters long, found on a sticker attached to the boiler casing or inside the front panel.
Decipher the Serial Number:
The 3rd and 4th digits of the serial number represent the year the boiler was manufactured.
For example, if the 3rd digit is ‘0’ and the 4th digit is ‘1’, the boiler was manufactured in 2001. |
| Worcester Bosch | On data badges pre July 2010, the FD (serial) number is located within the long serial number. The 11th, 12th and 13th digit. e.g. 7716130155 6842205631(6 is the year 4 is the month)
On data badges after July 2010, the FD number is located in a different location e.g. 5570 006 000334 7716130137. As our Greenstar boilers were not manufactured until 2005 the FD example above would be June 2010. |

Ideal Logic Boilers:The serial number will likely be a 24 or 25-digit number preceded by a two-letter prefix. The last few digits (usually the last six) represent the manufacture date. Pre-2015 boilers use a YY/MM/DD format (year/month/day), while post-2015 boilers use a DD/MM/YY format (day/month/year). The 4-digit code (16th or 17th character onwards) indicates the year and week of production. Ideal Classic Boilers:The serial number is shorter, consisting of 17 or 18 numbers. The third group of numbers represents the year and week of production.
For example, if the third group is 0612, the boiler was manufactured in the 12th week of 2006

2️⃣ Dig Through Your Paperwork 📚
Next, check your installation manual, receipt, or home documents. These often include the install date, which is usually within a year of the boiler being made.
🎁 Bonus tip: If you just bought the house, your home survey report may just mention the boiler’s age.
3️⃣ Use the Gas Safe Register 🔐
In the UK, every boiler installation is recorded with the Gas Safe Register.
Just visit gassaferegister.co.uk, type in your postcode, and you might find:
-
The exact installation date
-
Who installed it
-
Whether it’s been serviced
Super handy, right?
4️⃣ Ask a Pro 👨🔧👩🔧
However, when in doubt, bring in a Gas Safe registered engineer. During a regular service, they can tell you the age, current condition, and how much life your boiler likely has left.
Think of them as your boiler’s doctor! 🩺
