5 Warning Signs a Boiler Needs Serviced in Lothian Homes
19th August 2025
Introduction
Your boiler works hard to keep your home warm, especially through Scotland’s long, cold winters. Regular servicing is essential to keep it running safely and efficiently. But how do you know when it’s time to book a service? As a trusted heating company serving Midlothian, East Lothian & Edinburgh, we’ve put together five common warning signs that your boiler may need attention.
1. Strange Noises 🔊
If your boiler has started making banging, gurgling, or whistling noises, it’s a sign that something isn’t right. These sounds can be caused by trapped air, low water pressure, or limescale build-up in the system. Ignoring unusual noises can lead to bigger (and more expensive) problems later.
2. Uneven Heating 🌡️
Do some rooms in your house feel cosy while others stay cold? Uneven heating or radiators that take a long time to warm up are often a sign that your boiler or central heating system isn’t working as efficiently as it should. A service can restore proper circulation and balance.
3. Yellow or Flickering Flame 🔥
A healthy boiler should burn with a strong blue flame. If you notice a yellow or orange flame, or one that flickers, this could be a sign of incomplete combustion — which is a serious safety risk. Always have a Gas Safe or Oftec engineer investigate immediately.
4. Leaks or Damp 💧
Any signs of water leaking from your boiler should be treated as a red flag. Even a small drip can point to worn seals, valve issues, or corrosion. Left unchecked, leaks can damage your boiler and your home.
5. Higher Energy Bills 💷
If your energy bills are creeping up but your usage hasn’t changed, your boiler could be running inefficiently. A service will check for faults, clean the components, and ensure your boiler is working at maximum efficiency — saving you money in the long run.
