I fit combi, system and conventional boilers across Newcastle and Northumberland. You get a fixed price before I start, and in most homes a straight combi swap is done in a day.
Worcester is my first choice. Vaillant second. If the budget is tighter, a Baxi gives you the best value for money without dropping to something I would not want to come back to.
Whichever we go with, I will tell you honestly which one suits your house and your budget rather than pushing you at the dearest one.
A straight swap, where the new boiler goes where the old one was, is the simplest job and the cheapest. A typical combi swap is £1,800 to £2,000, depending on how much pipework is involved and what type of flue it needs and how long it is.
It goes up when there is more to do. Converting from a conventional system to a combi means new pipework, taking out the tank and cylinder, and making good afterwards. Moving the boiler to a different wall or a different room adds work. Long flue runs and vertical flues through the roof add time and materials.
You get the price before I start, and it does not change unless we find something neither of us knew about.
A new boiler going onto a dirty system is the quickest way to wreck it. So every install I do gets a proper flush first.
I use a MagnaCleanse. That is two high powered magnets fitted onto the system, and I can introduce heat while it runs to hot flush it. The magnets pull out any metal that has broken down inside the radiators, and the rest of the muck gets flushed away down the drain.
That matters because it is the metal debris off old radiators that damages a new boiler. Get it out at the start and the boiler has a clean system to work with from day one.
A lot of quotes include a chemical flush, which is not the same thing. If a price looks cheaper than mine, this is usually where the difference is.
Every boiler I fit gets registered with the manufacturer in your name, so the guarantee starts the day it goes in and you have got the paperwork behind it.
Guarantee lengths are set by the manufacturer rather than by me, and they normally run between seven and ten years depending on the make. I will tell you exactly what yours comes with before you decide.
A day. Old one out, new one in, tested and registered before I leave.
Usually two days, sometimes three depending on the pipework.
A straight swap is a day. A conversion is usually two, sometimes three. I will tell you which yours is when I come and look, not after I have started.
Depends what is booked in, but I will give you a date rather than a vague answer. If it is an emergency and you have no heating or hot water, say so and I will work around it.
Tell me your budget and I will tell you straight whether it is doable. If it is not, I would rather say so than start a job I cannot finish properly for the money.
I price the job on what it actually takes, so I will not always be the cheapest. What I will do is tell you exactly what is included, so you can see what you are comparing. A cheaper quote usually leaves something out.
Sheets down, tidy as I go, and everything taken away at the end. You should not be able to tell I have been there apart from the new boiler.

Bedlington
An old combi in Bedlington with too many faults to repair economically. I swapped it for a new Baxi combi in the loft, fitted a safe floor base and a loft ladder so the boiler can be serviced and maintained properly.

Northumberland
An old combi in a tight cupboard swapped out, with the pipework tidied, a magnetic filter fitted and the system flushed before commissioning.

Northumberland
An old electric boiler and a cupboard full of tangled pipework swapped for a modern unit on a tidy, labelled copper layout.
Tell me what you need and I will come and look at it. You get the price before I start.
