Let us help you to find the best types of boiler brands

Choosing a quality boiler brand is crucial. If you already spending hundreds of pounds on a boiler installation, make the most out of it!

Our opinion is in order to receive the best boiler, to reduce your bills, increase the power of your central heating system, it is essential to choose a high-quality brand. (leave the rest with our professionals, they will help you, to give recommendations, which will be the most suitable for your system, property and lifestyle) We are working only with well-known brands in the UK, reliable, a maximum value for the money, and with and we can reassure they will make a long lifespan, and serve you for decades. Also, it is important to consider the years of warranty, the manufacturer provides. Low-quality boiler manufacturers give up to 2-5 years of warranty, compared to the high-quality boiler makes which can be high as 12 years of parts and labour warranty. Huge difference, so it is something you have to consider in the first place.

Just to name a few brands we are installing:

Vaillant, Worcester-Bosch, Viessman, Baxi, Ideal.

When do you need a new boiler?


This question we hear very often. Obviously, people like to keep their boiler alive, as long as they can, but there are some signs when the alarm goes on.


    1. Very old boiler (we consider old boiler after the age of 10 years)
    2. Your boiler often needs to be repaired
    3. Your old boiler and system are not suitable for your property. (no pressure etc)
    4. Inefficient boiler
    5. Home extension
    6. Relocation, or central heating system upgrade
    7. Increasing the saleability of your property


There are many reasons for the installation, contact us if you need help on 020 8355 0840.

1.How much does a plumber charge to install a boiler?


We can’t tell enough. Only a gas safe registered engineer is competent to work on gas appliances, whether it is a boiler or a gas hob.


Call us on 020 8355 0840, to request a visit by a registered gas engineer.



2.How do I find a good boiler installer?


You just found one. We mentioned above all the advantages we are coming with. There is a lot of important things to check and consider before you hire someone.


1.) We always recommend working with a limited company like us. First of all, limited companies require to have Public liability insurance up to £ 2 million.


2.) Limited companies have more investments, so they have more to lose. This fact makes the companies being more reliable, and trustworthy than others.


3.) Good presents are everything. Check the reviews everywhere. Find out our customer’s experiences.


4.) Website. Some of you already know the amount of work and money you need to maintain, and advertise a business website. I think this investment shows the business’s intention. If a tradesman just presents on free sites and advertising for free, that is not a good sign.


5.) Recommendations. Again, reviews, and word of mouth. We have worked with many homeowners, businesses and landlords across Barnet, and within North London. Probably already worked for your neighbours or family members as well.


6.) Contacts. For us the appearances are crucial. Small things such as personalised email addresses, or having a landline office number can mean a lot. This again shows, the company’s intention, if they are investing money to grow their business, or not and happy with a mobile number to serve their customers.


7.) When it comes to boiler installation, the most important thing is to check is the company GAS SAFE REGISTRATION NUMBER. Do not hire someone without the right qualification to install your boiler, because their offer is a little cheaper. It can cost your own safety. You can find our Gas Safe Registration number at the bottom of our website. We also recommend asking the gas engineers gas safe card with a photo, on the appearance. Unfortunately, it is a very common method by companies, to send out someone with only experience but no qualification. The company itself is registered, but not the engineer. Our engineers are registered individually, please feel free to ask for their photo cards upon arrival.


8.) Companies House check.


As we said earlier, it is always worth using a limited company rather than anything else. However, there are still some companies acting as a company, and they are already dissolved. Please always check, who you are inviting into your property.  

Just to mention a few tips before you consider getting a big job done like a boiler installation to think about. Hope it helps.
