These sorts of boilers do not provide cold water and hot water on demand, which is why many people have made the move to a combi boiler. ideal boiler cost

  • There also needs to be new upgraded pipework, which is fed into the new location of the incoming combi boiler or existing location.

What impacts how much a new boiler costs? energy saving costs

There are a number of different factors that influence the cost of a boiler.

On the surface, it may seem like it is just the installation cost and the cost of the unit itself.

However, there are a number of factors that add to the new boiler cost, and so we are going to delve into these in further detail.

The cost of the boiler itself

Of course, there is only one place to begin, and this is with the price of the boiler itself.

The price of a boiler differs by hundreds of pounds, if not thousands.

It all depends on the quality of the boiler, as well as the brand, kW size, and model.boilers cost

Later in this guide, we are going to take a look at some specific brands of boilers, as well as the average cost of these boilers. ?

The typical new boiler cost is anywhere from £400 to £1,200.

However, there are some much more expensive units on the market today such as the Megaflo unvented boiler range.

The installation price / labour cost ideal boiler prices

For a boiler swap, the cost of installation is anywhere from £600 to £800 on average. This depends on the size of your home and what size boiler is required to heat your home.

The cost of conversion on average tends to be between £1,000 to £1,500. For example a back boiler swap or conversion.

It is important to choose an installation specialist with care.

For many years, heating specialists were watched over by the official watchdog CORGI (the Council of Registered Gas Installers). The CORGI brand was synonymous with quality and safety.

If you got a CORGI engineer in to perform a new combi boiler installation, you knew you’d be getting quality work done.

However, CORGI wasn’t mandatory and was a voluntary registration scheme. That meant there was a whole load of heating specialists out there fitting combi boilers who weren’t registered. ❌

While some of these combi boiler installation labourers were probably good at their job and annoyed by the costs associated with being a part of CORGI, many would have been those who didn’t pass the CORGI examinations. This meant that anyone could claim to be a heating boiler and installation expert. new boiler gas safe installation cost

Thankfully that changed during 2009 and 2010 when the Gas Safe Register replaced CORGI.

This made it mandatory for all central heating combi boiler installation and servicing workers – including those performing combi boiler repairs or boiler installation jobs – to be registered.

In order to be part of the registry, combi boiler installation experts have to have the proper qualifications to work on any boilers. So always ask to see your installer’s Gas Safe Register card for proof of their credentials.

Unfortunately, there are a lot of unscrupulous workers out there that will try to fit boilers without the right experience and credentials.

Don’t cut corners by going down this route, as it can end up costing you thousands and thousands of pounds in the end. ❌best boiler deals

Upgraded warranty costs

In addition to the costs that have already been mentioned, extended warranties, especially ten-year warranties in most cases, are only able to be provided by trusted manufacturers and partners.

They can sometimes rely on additional approved equipment being fitted.

For example, magnetic boiler filters. They will tend to results in additional costs being added to the installation.

However, there is no denying that a longer warranty is an expense that is worth incurring. It could end up saving you a lot of money in the long run!

Upgraded heating control costs thermostat cost

Thanks to upgrades in technology in recent times, boilers can be turned on and off with ease. You do not have to walk to the boiler in order to make changes.

Depending on the brand and type of the controller, it is going to add varying figures to the new boiler price.

The average price of this is between £100 and £300.

Relocating the boiler

You may need to move the location of your boiler. This is going to cost more money, which is going to require a number of new fittings and fixtures, as well as emotional robustness, additional pipework, and a lot of physical labour.

Unless moving your boiler is vital, it is always a good idea to avoid this. If you are going down the back boiler removal and replacement route then you must now convert to a combi boiler.

Main gas pipe upgrade gas pipe cost

You may also need to have the main gas pipe upgraded.

A lot of the older heating systems are constructed using gas piping of a width around 15 mm.

However, in order for modern regulations to be met, these pipes need to be upgraded to 22 mm in most cases. This can sometimes cost more money.

In most cases, older pipes will also be made from lead, and so they will need to be replaced using copper piping.

You need to be cautious of rogue traders who do not plan to upgrade the pipework. This would be an illegal installation, and so while it may be cheaper, it is certainly not worth the risk – that much is certain!

Plume kit cost plume kit costs

A plume kit is basically an extension kit that attaches to the flue of the boiler. This can be required when your boiler flue is too close for comfort to your neighbouring properties, door, or window.

Plus, it must comply with Gas Safe regulations by law.

The typical cost of a plume kit is anywhere between £90 and £130.

Chemical flush cost

You may also need to pay for a chemical flush. This can be anything from £100 to £150.

Flushes help to get rid of any existing sludge from your heating system. Sludge can prevent the hot heating water from flowing efficiently around your radiators if you do not clear it. ♨ chemical flush cost

If your radiators are cold at the bottom, a deep clean is going to be required. There are a lot of different options when it comes to this. ❄

However, the most common and standard option is a hot, chemical flush. For a power flush, you can pay more than £500.

Be careful with these, as they can often do more damage than good by forcing high pressure water through a heating system, especially if it is an old one.

Vertical flue

A boiler flue is basically a big piece of pipe, which leads from the boiler to the outside of your property.

This makes sure that the flue gases and condensation are pumped outside and not into your own face. Pretty important, right??‍

Most of the time, the flue is going to leave your home horizontally, which means that there are no extra expenses.

However, flues that leave vertically through your roof demand much more work, resulting in more expenses. This can just be plain bad luck.

The average cost for a flue is anywhere from £300 to £600.

Magnetic boiler filter cost

The average cost of a magnetic boiler filter is between £100 and £200.

Filters are installed inline on the pipework, helping to protect your boiler.

They utilise powerful magnets that trap small particles of metal and dirt, stopping them from going into the boiler itself and causing unnecessary boiler leaks and damage.

A quality boiler installation specialist is always going to put together the full cost of installation a filter into your final quote.

You should not be stung with added expenses at the end. boiler costs 2020
