About me

Expert Boiler Servicing in Belfast & Beyond

No big call centre. When you ring, you'll get me - Mark. I'll come round, take a proper look at your boiler, and tell you straight what's going on. If it's a quick fix, I'll say so. If it's not, I'll explain why and what your options are.

I work right across Belfast and Co. Down - from North Belfast and the Holywood Road out to Lisburn, Bangor and Newtownabbey. Gas Safe and OFTEC registered, so I can service oil and gas boilers from every major brand: Worcester Bosch, Baxi, Vaillant, Grant, Firebird, Ideal - you name it.

The usual questions

Things folk ask before they ring.

Once a year, every year. Most manufacturers' warranties actually require it - and a yearly service catches little problems before they turn into a cold January morning with no heat.
Usually about an hour for a standard service, maybe a bit longer if I find something that needs attention. I'll always tell you up front if it's going to take longer.
They check different things. Oil services involve a proper strip-down of the burner and a combustion test. Gas is more about safety checks, seals and flue tests. I'm registered for both, so either way you're covered.
Yes - and that's actually the best time to do it. A boiler that's working fine today is much cheaper to keep working than one that's just packed in. A yearly service usually pays for itself in efficiency.
Yep. CP12 gas safety certificates for landlords, all signed and emailed to you on the day. I do a lot of work for landlords across Belfast - happy to set up annual reminders too.
Ring me anyway. I'm happy to chat through what's going on - sometimes I can talk you through resetting the boiler or topping up the pressure without me coming out at all.
Ready when you are

Quickest way to get sorted is a quick phone call. Tell me what's going on and I'll let you know when I can be round. If it's outside hours, leave a message - I'll come back to you first thing.
