If you find yourself faced with the problem of owning an old, failing boiler that is beyond the point of economical repair, the chances are you going to spend a reasonable amount of time shopping around to find the right new boiler at the right price, and also, wondering what to do about the actual boiler installation in and around Sheffield!
Because boiler installation is a large, complex task, the cost of the installation itself can often mirror the cost of the boiler, or even more in some cases. It is of course vitally important that you do not attempt to put a new boiler in or remove your old boiler and install the replacement yourself, as this should only be carried out by a Gas Safe Registered installer who is a qualified heating engineer.
The Building Regulations and Gas Safety (Installation and Use) laws mandate that all boiler installations must be carried out by a competent person, which essentially means hiring a registered Gas Safe installer to complete the job. The Gas Safe Register replaces the previous Corgi regulation, which, if your last boiler was installed prior to 2009, may well be the certification that you are more familiar with.
Different types of boiler installation Available in Sheffield
There are several different types of common household boilers, and exactly what is involved in installing each of them-and so, the associated cost-can vary considerably.
The vast majority of boilers in the UK’s homes are gas fuelled, however, oil boilers are also another option, which prove popular in many rural areas where a mains gas supply is not available, or where the types of property and the work involved to install a gas system is likely to prove prohibitively expensive.
Whilst the amount of work involved in any given boiler installation will have potentially the largest impact on the ultimate cost of the job, other factors including demand and supply in the area that you live in, and the parts that may be needed to complete the job will all have some influence as well.
Your boiler installer may well recommend certain types of boilers for your project and can potentially source and supply them for you, but generally, the cost of installing or replacing a boiler is based on the price for the installation alone, with the purchase price of the boiler being dealt with separately.
We will look at the most common types of boiler installations in more detail below, but remember that once you have found an installer who will work on your particular boiler installation, check before hiring them that they are on the Gas Safe Register.
Here’s a quick run-down of the basics of the most common home boiler systems, and the work and so, approximate costs involved in their installation or replacement when hiring an independent contractor that is a member of the APHC (Association of Plumbing and Heating Contractors).
Replacing a gas-condensing combi boiler
If your heating system is relatively modern, replacing a gas-condensing combi boiler with a like-for-like alternative can cost anywhere between £500-£800. If your heating system is old and ailing, you may also need to budget for having the system mechanically flushed with the appropriate cleaning chemicals, which is a large and complicated job that may increase the price by several hundred pounds.
Installing a condensing boiler in place of a non-condensing one
Replacing a condensing boiler with a non-condensing one in the same place and using the existing flue can cost £600-£900 on average, but if some of the associated pipework needs to be replaced or altered, this can all add to the cost. Once again, if your gas system is old and requires mechanical flushing, this too can make the job more expensive.
Replacing a heating-only boiler with a condensing combi boiler
This is a bigger job than the average install, as your engineer will need to convert your existing gas system from a vented one to a sealed one, which requires the replacement of all of your old, obsolete equipment including the cold water tank, expansion tank, and the hot water cylinder. The job may also involve major re-plumbing work, and can cost anything from £1,400-£2,000 plus, or even more if your system also needs mechanical flushing.
Oil boiler installation or replacement
Oil boilers and oil heating systems are of course an alternative to gas boiler installation systems, and such systems come accompanied by large oil storage tanks that must be filled by road-delivery tankers.
If you have an oil system or wish to have an oil boiler installed, it is important to select an engineer that is competent and experienced in working with oil boiler systems, as many gas plumbers are reluctant, or not certified, to work on them.
This means that finding someone who can perform the boiler installation for an oil system can be challenging in some areas, although in regions where oil heating is the norm due to a lack of mains gas supply, it should be somewhat easier.
Oil boiler installation tends to cost rather more than gas boiler installation due to the smaller number of heating engineers who are competent and experienced at working on such systems, and the price can vary significantly from job to job due to the potential number of variables involved.

Finding someone competent to take care or your boiler installation
It is important to find a heating engineer who is competent and experienced in working with the type of boiler that you wish to install, as many professionals specialise in certain types of boilers, and will not be keen to work on others.
You can check the veracity of your installer’s claims by checking them out on the Gas Safe website, or by calling the helpline on 0800 408 5500. Every Gas Safe installer is required to carry an ID card that cites the types of gas installations that they are qualified to work on, so make sure that the information on their card tallies up with what they are telling you, and if necessary, verify this with Gas Safe itself.
