The cost of a new boiler can vary significantly, typically ranging from £500 to £3,500 for the boiler unit alone, and between £1,500 and £5,000 when including professional installation. The exact price depends on several factors, primarily the type of boiler you choose and the complexity of the installation.
Boiler Cost Breakdown by Type
Here’s an overview of average boiler costs, broken down by type and whether installation is included:
| Type of Boiler / Fuel Source | Cost (excluding installation) | Cost (including installation) |
|---|---|---|
| Combi Boiler | £500 - £3,000 | £1,500 - £4,500 |
| System Boiler | £580 - £3,500 | £1,580 - £5,000 |
| Conventional Boiler | £600 - £3,500 | £1,600 - £5,000 |
| Electric Boiler | £590 - £2,500 | £1,590 - £4,000 |
Factors Influencing Boiler Costs
Several key elements contribute to the overall price of a new boiler installation:
- Boiler Type: As shown in the table, different types of boilers (combi, system, conventional, electric) have varying price points based on their technology and complexity.
- Boiler Brand and Model: Premium brands or models with advanced features will naturally cost more than standard options.
- Boiler Size (Output): Boilers are sized in kilowatts (kW) to match your home's heating and hot water demands. A larger, more powerful boiler generally costs more.
- Installation Complexity:
- Location: Replacing an existing boiler in the same spot is usually more straightforward and cheaper than relocating it to a different part of the house.
- Pipework and Flue Requirements: Extensive alterations to existing pipework, gas lines, or flue systems will increase labor costs.
- System Upgrades: If your old heating system requires upgrades to accommodate a new boiler (e.g., new radiators, cylinder, or controls), this will add to the total expense.
- Boiler Conversion: Converting from one type of boiler to another (e.g., conventional to combi) often involves significant work and is typically more expensive than a like-for-like replacement.
- Labor Costs: Installation fees vary based on the installer's experience, location, and the duration of the job.
When budgeting for a new boiler, it's advisable to obtain multiple quotes from qualified heating engineers to get a precise estimate for your specific circumstances.
