THE WORK

What the job involves

When a boiler is beyond economic repair, we replace it. We size the replacement to the property rather than simply matching what was there, confirm what the existing system will take, and agree a fixed price before any work begins.

What's included

  • Honest advice on repair versus replace

  • Correct sizing for the property, not a like-for-like guess

  • Fixed price agreed before we start

  • Old boiler removed and taken away

When a boiler replacement is the right call

Replacing a boiler that still runs feels wasteful, and sometimes it is. These are the situations where it usually is not.

Parts have gone obsolete. Once a manufacturer stops making a component, a fault that would have been an hour's work becomes a search. Some models reach a point where the next failure ends it, whatever anyone does.

It is non condensing. Older boilers vent heat out of the flue that a condensing appliance recovers. That is a cost on every bill, not just when something breaks.

The repairs have become a pattern. One component failing is bad luck. Three in two winters is a boiler telling you something.

The house has changed. An extra bathroom, an extension or a loft conversion changes the demand. A boiler that was correctly sized ten years ago may not be now.

It is in the wrong place. Replacement is the moment to move it, because the disruption is already happening. Doing it later as a separate job costs far more.

What a straight swap actually involves

A like for like boiler replacement in the same position is the least disruptive version of this work, but it is not simply unbolting one and hanging another.

The existing system gets cleaned, because a new appliance on old debris will not last. The gas supply is checked against the new boiler's requirement, which is not always the same as the old one's. The flue is replaced rather than reused, since it is matched to the appliance. Condensate needs a route to a suitable drain, and on older properties that route sometimes does not exist yet.

Then the new boiler is commissioned properly: gas rate set, combustion analysed, readings recorded, Benchmark completed. Finally the work is notified under Building Regulations and the guarantee registered in your name.

What replacement does not fix on its own

Worth knowing before you spend, because a new boiler gets blamed for these afterwards.

  • Cold spots in radiators are usually sludge or balancing, not the boiler. If the system is not cleaned properly the new appliance inherits the problem.

  • Poor mains water pressure limits what a combi can deliver. A new boiler cannot create flow that is not coming into the house.

  • Rooms that never get warm are often undersized radiators or heat loss through the fabric of the building.

  • Ancient controls waste the efficiency you just paid for. A modern boiler with a mechanical timer and no thermostatic valves is running blind.

An honest quote should tell you which of these apply to your house before the work, not after.

I arranged for a plumber from Nelson Plumbing and Heating to replace an isolation valve at a property in Salford. The plumber turned up on time, did a fast and professional job. Price was cheaper than the estimate. Great service and will be my go to plumber for any further work required in the Manchester area.

They arrived promptly as arranged and both introduced themselves and interacted very well with our dog. They installed our new boiler very efficiently and professionally, giving honest advice on which services we may require in the future.

I cannot recommend Turrell highly enough. He was an absolute pleasure to deal with and professional from start to finish. He took his time to explain everything clearly, which immediately put me at ease, something that is a massive deal for me when dealing with the building trade.

Friendly and helpful service. I was really impressed with Tom who undertook diagnostic testing and then the replacement of parts on my water system in the house. Thank you for the quick turnaround and efficient service.

Once a boiler is past twelve years old, needs repeated repairs, or has a failed major part such as a heat exchanger, replacement usually makes better financial sense. If it is an old non condensing unit, the efficiency gain is significant on top.

Yes, and a replacement is the natural time to do it. Moving into the kitchen, garage or loft is common. It adds pipework and flue routing so it takes longer than a straight swap, and it should be priced honestly up front rather than added later.

No, in most cases. The system does need cleaning and a magnetic filter fitting so debris off old radiators does not damage the new boiler, and that condition normally sits in the manufacturer warranty as well.

Water off for most of the day, heating back on the same evening for a like for like swap. Where the boiler moves position, allow a second day. We agree the plan before we start so you can work around it.

Warranty length depends on the manufacturer and the model chosen, and it is registered on your behalf after installation. Every one of them requires an annual service to stay valid, so budget for that from year one.
