North East Boiler Advice from R & B Plumbing and Heating
Most boilers have a serial number on the underside or inside the casing — this often includes the manufacturing date. If your boiler is more than 10–15 years old, it may be running inefficiently and could be costing you more in energy bills than necessary.
📌 Top tip: If you can't find the age, we’re happy to help check for you.
The make and model of your boiler can usually be found:
In the user manual
On the data plate (usually behind the flap or inside the case)
Knowing your boiler’s model helps us give tailored advice on repairs vs. replacement.
Older boilers tend to be rated lower than today's modern A-rated condensing boilers, which are over 90% efficient. If:
Your energy bills have crept up
The boiler is slow to heat
It makes odd noises
The flame is yellow instead of blue
…it could be time to review your options.
Boiler repairs can be costly — and sometimes it’s more economical long-term to replace rather than repair. We help customers across the North East decide whether it’s worth the investment, based on:
Age of the system
Cost of ongoing repairs
Energy savings from a new unit
Lower gas bills due to higher efficiency 
Quieter operation
Compact modern designs
Peace of mind with new warranties (up to 10 years)
Environmentally friendly
