Straight answers, from the people doing the work
The questions BPS Plumbing & Heating get asked most, answered properly — no hedging, no filler. Written by the engineers on the tools, not by a marketing department.
How long does a boiler last?
Most domestic boilers last 10 to 15 years. Here is what decides whether yours is at the top or the bottom of that range.
How often should a boiler be serviced?
Once a year, every year — and not only because the manufacturer says so. Here is what a service actually covers.
How long does a boiler service take?
Around 30 to 45 minutes for a straightforward service. Considerably longer is not a bad sign.
How long does it take to fit a boiler?
A straight swap is usually one day. Moving the boiler or changing system type takes two or three.
What size boiler do I need?
Bigger is not better. An oversized boiler costs more to buy, more to run, and wears out sooner.
What is a combi boiler?
One unit that does heating and hot water on demand, with no cylinder or tanks. Excellent for most homes — not all.
Why is my boiler making a noise?
Banging, whistling and gurgling each point at different faults. Here is how to tell them apart.
How to detect a gas leak
The smell is the obvious sign, but it is not the only one. What to look for, and exactly what to do.
Will a new boiler save me money?
Usually yes — but the honest answer depends on what you are replacing and how long you plan to stay.

Is boiler breakdown cover worth it?
It depends on the age of your boiler and your appetite for a surprise bill. An honest look at both sides.
Signs you should replace your plumbing
Repeated leaks, discoloured water and dropping pressure are the system telling you something.
Plumbing or drainage — what is the difference?
Plumbing brings clean water in. Drainage takes waste away. Knowing which you have saves time and money.
