My boiler was faulty this morning. Armand was quick to get to us just before noon, figured out the issue, arranged the part to be picked up and was back within 1-2 hours to carry out repairs. Works lasted for 1 hour. He fixed the problem was extremely helpful and polite. Thank you so much. I recommend to anyone who has any issues to do with regards to boiler repairs

Excellent experience, highly recommended! I called on Friday morning and had an engineer come over on the same day, identify the issue, find a replacement part and come back on Saturday to fix the boiler. Great service, I will use again.

Armand did a fantastic job - I needed two radiators taken off the walls before I had damp proofing done then replaced again afterwards. He was easy to communicate with, very professional and able to do the job quickly. Would definitely recommend.

Did a really great job fixing the bathroom. We had a leaking bathtub and moldy grouting. Took care of the leak very quickly and professionally, and re-grouted the tub as well. It all looks as good as new!

Pete French Designation

Very good service. Initially I simply had my bath taps replaced, but I then also had a heated towel rail fitted (which involved a full drain of the central heating), and both times I feel the job was done excellently. Both jobs done fast and efficiently, well within the quoted time, and left the place clean and tidied as well. Would definitely use any time I need to have any more plumbing work done.

Alys Wang Designation

Boiler Installation in London FAQs

Before installing a new boiler, consider the size of your home, your heating requirements, the type of boiler most suitable for your needs (e.g., combi, system, or conventional), and energy efficiency ratings. It’s also important to choose a Gas Safe registered engineer for installation.

Boiler installation in North London can typically take 1-2 days, depending on the complexity of the job and whether it's a straightforward replacement or a complete system overhaul.

Upgrading your boiler can increase energy efficiency, reduce heating bills, lower carbon emissions, provide better temperature control, and ensure more reliable heating and hot water supply.

The best boiler type depends on your home's size and your heating and hot water demands. Combi boilers are great for small to medium-sized homes with one bathroom, while system or conventional boilers are better suited for larger homes with multiple bathrooms.

The cost can vary widely depending on the type of boiler, the complexity of the installation, and whether additional work like relocating the boiler or replacing radiators is needed. Prices typically range from £1,500 to £3,500.

Regular maintenance, including annual servicing by a Gas Safe registered engineer, is crucial to ensure your boiler operates safely and efficiently. This not only extends the life of your boiler but also helps prevent unexpected breakdowns.

Boiler installation can be costly due to several factors including the price of the boiler itself, the complexity of the system installation, and the labor involved. High-quality boilers are an investment in energy efficiency and long-term reliability, which contributes to the initial cost. Additionally, installation may require modifications to your home's existing heating system, safety checks, and compliance with local building regulations, all of which require professional expertise.
