Over time, soot builds up within the combustion chamber, reducing its efficiency and costing you money. Getting your boiler checked on a regular basis greatly reduces the risk of expensive breakdowns and keeps the appliance running as efficiently and as safely as possible. As oil boilers work a little differently, it's important to contact a company you trust to take care of yours. Switch your appliance off immediately if you detect any smells or fumes. 


At SMB, we've been servicing for nearly 2 decades and will give your boiler the once over to make sure it's working properly. We also provide Carbon Monoxide alarms to help keep you safe.

Need a new nozzle?

As you can see, a service is great value for money as we check every part of your system. There is one part that's particularly important that you need to be aware of. The nozzle is perhaps the most important part of the burner. It's vital that it works properly because if it doesn't it can compromise combustion, reducing the efficiency of your boiler and potentially become dangerous. At SMB, a new nozzle comes as standard with every service, giving you one less thing to worry about. Get in touch today. We cover Haverfordwest, Narberth and the surrounding areas.
