Boiler installation and replacement in Birmingham
Need a new boiler in Birmingham? We install all makes and models of gas boiler, from combis to system and conventional boilers. A 25kW combi costs from £1,750, supplied and fitted. Our Gas Safe registered engineers start with a free survey. Then you get a fixed price, and a typical install takes one day.
Boiler installation jobs we do
These are the new and replacement boiler jobs we do in Birmingham. We fit all makes.
- Combi boiler installation: A combi heats water straight from the mains when you turn on a tap. It needs no tank or cylinder.
- System boiler installation: A system boiler stores hot water in a cylinder. It suits homes with two or more bathrooms.
- Conventional boiler installation: Also called a regular boiler. It works with a cold water tank in the loft and a hot water cylinder.
- Like-for-like boiler replacement: Your old boiler swapped for a new one of the same type. This is usually the quickest job.
- Switching to a combi: Your old cylinder and loft tanks come out, and a combi takes over your hot water.
- Back boiler replacement: A back boiler is an old type that sits behind a fire, in the fireplace. We swap it for a modern boiler.
- Moving a boiler: Your boiler fitted somewhere new in your home. We plan the new pipes and flue at the survey.
- Hot water cylinders: Old cylinders replaced, including unvented ones. An unvented cylinder runs at mains pressure, with no loft tank.
- Power flushing: A deep clean that pushes sludge out of your pipes and radiators, so the sludge doesn't clog the new boiler.
Boiler brands we install
We fit all makes and models of gas boiler, so you aren't stuck with one brand. Here are the makes we install in homes across Birmingham:
We're independent Gas Safe engineers, not tied to any one maker.
Most of these makers offer more than one type of boiler. At the survey, we look at your home and talk you through the choices. Then you pick the one that suits you. We repair and service all makes as well.
Thinking of going electric instead? We fit electric boilers too. See our electric boiler installation page.
How much does a new boiler cost in Birmingham?
A 25kW combi boiler costs from £1,750, supplied and fitted. That's our starting price. Other boiler types and sizes are priced after the free survey.
Combi boiler (25kW), supplied and fitted: from £1,750
Every home is different, so we come out for a free survey first. Then we give you a fixed price. You know the full cost before any work starts. These are the main things that change it:
- The boiler type and size. A combi, system or regular boiler, and how powerful it needs to be.
- The make and model you choose. Prices vary from one boiler to the next.
- Like for like, or a change. The same type of boiler in the same spot is the simplest job.
- Moving the boiler. A new spot needs new gas and water pipes, and a new flue.
- A combi conversion. Taking out the cylinder and loft tanks adds time and pipework.
- The flue. This is the pipe that takes waste gases outside. Some homes need a longer or different route.
- The pipework. Old or narrow pipes sometimes need to be changed to suit the new boiler.
- Cleaning the system. A dirty system may need a power flush before the new boiler goes in.
If your system is already clean, we'll say so. You won't pay for a flush you don't need.
What's included
- A free survey of your home, hot water use and existing system
- A fixed price before any work starts
- Supply and fitting of your new boiler and flue
- Commissioning (setting up and testing the boiler) and Building Control notification
- Our work guaranteed for 12 months, parts and labour
Combi boiler installation and combi conversions
With a combi, you get hot water on demand and lose the tanks. That's why many people swap an old system or regular boiler for one. We call this a combi conversion.
On a combi conversion, this is what happens:
- At the survey, we check your mains water pressure and flow.
- We take out the old hot water cylinder.
- We take out the cold water tanks in the loft.
- We change the pipework to suit the new boiler.
- We fit and set up the new combi.
The cylinder cupboard is free to use again. With the old tanks gone, they can't leak either.
A combi isn't right for every home. It works best with one bathroom and good mains water pressure. In a bigger home where two showers run at once, a system boiler with a cylinder is often the better choice. We'll tell you honestly which suits the way you live.
Moving your boiler to a new spot
We can move your boiler to a new spot in your home. People often want it out of the kitchen, or hidden in a cupboard or the loft. The new spot needs a gas supply and a safe route for the flue. It also needs a drain for the condensate pipe, the small pipe that carries waste water away. We check all of this at the survey.
Back boiler replacement
Still got a back boiler behind your fire? It's an old design that is no longer fitted in new homes. Once it's out of the fireplace, the new boiler needs a fresh home. At the survey, we look at where it can go, and how the flue will reach outside. Then we give you a fixed price for the whole job.
When to replace rather than repair
Is the boiler more than 12 years old? Has it broken down more than once this winter, or does it need a major part such as a heat exchanger? Then replacing it usually works out cheaper over the next few years. If a boiler repair makes more sense, we will say so. Our boiler fitters in Birmingham would rather fix a good boiler than sell you a new one you don't need.
Picking the right size
Boilers come in different power outputs, measured in kilowatts (kW). With a combi, a bigger output means hot water comes out of the taps faster. Too small and showers feel weak. Too big and you've paid for power you don't use.
The right size depends on how many bathrooms you have, how many radiators, and how strong your mains water pressure is. That's why we survey first instead of guessing over the phone.
How a boiler replacement works
Here's what happens on the day of a straight swap.
- We drain down the heating system.
- The old boiler comes out and the new one goes in, with a new flue if needed.
- The system is refilled and checked for leaks.
- We test everything and show you how the boiler works.
- You get the paperwork: the commissioning checklist and Building Control notification.
Looking after it
Get it serviced once a year to keep the maker's warranty valid. Glance at the pressure gauge now and then: with the heating off, it should usually sit between 1 and 1.5 bar.
Common questions
Which type of boiler do I need?
Most homes with one bathroom suit a combi boiler. Homes with two or more bathrooms used at the same time usually do better with a system boiler and a hot water cylinder. Older homes with a loft tank may keep a conventional (regular) boiler. We will recommend one after seeing the property.
How much does a new boiler cost?
A 25kW combi boiler costs from £1,750 with us, supplied and fitted. A bigger boiler, a different type or extra work changes the price. Extra work means things like moving the boiler, a combi conversion or new pipework. We give you a fixed price after a free survey, so you know the cost before we start.
Can you convert my system to a combi boiler?
Yes. We take out the old hot water cylinder and the tanks in the loft, then fit a combi in their place. First we check your mains water pressure and flow at the survey. A combi needs both to be good, or your showers will feel weak.
Can you move my boiler to a different room?
Yes. Plenty of people want the boiler out of sight, for example up in the loft. We check the new spot works at the free survey. Your fixed price then includes the move.
Do you replace back boilers?
Yes, we replace them with a modern boiler, after a free survey and a fixed price. Repairs and servicing on back boilers aren't something we do.
Is your work guaranteed?
Yes. All our work is guaranteed for 12 months, parts and labour. This is our own guarantee on the work we do. Your new boiler also comes with the maker's own warranty, which is separate from ours.
Which boiler brand do you fit?
We fit all makes and models of gas boiler. The brands we fit are Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, Glow-worm, Alpha, ATAG, Vokèra, Ferroli, Intergas, Biasi, Ariston, Potterton, Keston and Main. Not sure which to pick? We will talk you through the options at the free survey. We also repair and service all makes.
How long does it take to replace a boiler?
Most of our boiler swaps are done in a day. A combi conversion or moving the boiler to a new spot can take longer, because of the extra pipework. We will tell you how long your job should take at the free survey.
How long does a boiler last?
Most modern gas boilers last around 10 to 15 years, if they are serviced once a year. It may be time to replace yours if it breaks down often or parts are hard to get. Rising gas bills and old age are other signs. We will tell you honestly if a repair makes more sense. See our boiler repair page.
Will I get paperwork?
Yes. By law, a new boiler must be notified to Building Control, and Gas Safe engineers do this for you. You also get a Benchmark commissioning checklist, which records how the boiler was set up. Keep these for the warranty and for when you sell the house.
Do I need a power flush before a new boiler?
Only if the old system is dirty. If it has sludge, cold spots on radiators or a history of breakdowns, cleaning it first protects the new boiler. A clean system is often a condition of the maker's warranty. We will tell you honestly if it is not needed. See our power flush page.
Do you fit electric boilers too?
Yes. We fit electric combi, system and heat-only boilers, with the same free survey and fixed price. We do the electrical work ourselves, such as the new circuit the boiler needs. See our electric boiler installation page.
