Your quick guide to the costs of installing a new boiler
The replacement of a boiler is an expensive home improvement job and best planned ahead of the colder months. A new boiler should last up to 20 years before a new one is required.
But what to do if you suspect a faulty boiler?
If you need a new boiler, you’ll want to purchase the right model for your home. The size of your house will determine the size of the boiler. You also must decide the fuel source: gas or electric. More energy-efficient models will save you money in the long run, but expect to pay more for those initially.
Installation process
You shouldn’t try to buy a new boiler and put it in by yourself. Installing a boiler isn’t a simple DIY project. It requires a lot of skill and training to do it right. You need a contractor to measure your home and determine which boiler will provide you with sufficient heating.
Depending on the boiler you choose, you may need to create additional space in your home or install it down a flight of stairs. These scenarios will increase the price. Furthermore, you’ll need someone who can remove and dispose of your old system.
Standard costs and installation time
No two boiler installations are quite the same. The total cost to replace your system depends on the price of the boiler you decide upon. Expect to pay about £1,000 to £3,000 for a new boiler. Labour will also make up a portion of the cost, which usually runs at about £250 per day. In most instances, the process only takes about one day, but if your installer runs into any issues, it may take longer.
Electric boiler installations are not as cheap as gas boilers, but can be considered safer. They also require far less servicing compared to a gas boiler. Are they energy efficient? Yes, as best as possible if insulated properly, though there are still energy emissions from the electricity generation. Expect a new electric boiler to cost from £1,300 plus labour costs, when using a professional electrician installing to British Standards 7671.
Gas boiler installations take a little more thought. A faulty one is more costly to operate and presents safety hazards. If you have one already, there are companies offering annual gas system safety checks to check the boiler and advise on a suitable replacement if required. Faulty boilers can release odourless carbon monoxide fumes so if yours is burning orange rather than blue, get it checked. If you suspect damage, you can also acquire a carbon monoxide detector. A gas boiler safety inspection costs from £60, or free if with boiler insurance cover. The replacement costs vary, but expect around £600 plus labour costs as a figure.
You can also consider an oil-fired boiler. A condensing oil boiler recycles heat to pre-heat up the water in the boiler, which is less costly on fuel and energy consumption. As the power needed for the oil boiler is stored in the tank, this is where the costs differ as opposed to gas boilers.
Switching fuel sources may increase the overall price. For example, if you choose gas, you must connect the lines and hire someone to perform safety assessments. Your contractor won’t handle this task; you’ll need to hire a private survey company.
Final considerations
No matter your budget, buy an energy-efficient model. Not only are these systems cheaper to run, but most last years longer than other options. It’s always best to purchase from a reputable company that provides a full guarantee.
Always ask for a written quotation before hiring a contractor. You can compare new boiler prices here and ask Moderniser for advice.
The quote should include the cost of installation, and the price of removing the old boiler and hooking up any lines. Reputable contractors will be more than willing to answer any questions you may have about your new boiler before they leave.
