Boiler Installation Prices in London
Combi Boiler installation Price
The cost of a Combi boiler installation price is going to vary anywhere between £1500 – 3500 depending on the boiler and the scope of the installation project.
If for instance:
- Your installation involves some alterations in your filter or flue, you can expect an additional £500 – 800 on the installation cost.
- The installation company you choose could also determine the price based on their experience and accreditation. Cheap boiler installation prices can be attractive at first site, but it is important to choose your installer wisely. Ensure your boiler installation company has the necessary qualifications and are Gas Safe Registered. Going for a cheap option might seem like a great choice in the short term, but it can easily cost you a lot more in the long run due to the boiler not being set up for maximum efficiency.
Regular Boiler installation price
Regular and System boiler installations are somewhat similar since the two boilers both require a hot water cylinder. Ideally, a regular and system boiler installation in London should range between £1750 – 4000. If the project involves fitting a new tank then the price might be North of £3000 or even go above the £4000 mark slightly.
The key difference between these boilers is a regular boiler involves a feed and expansion tank therefore any alterations within the tank might hike up the price. A system boiler relies on water from the mains.
