"My 25 year old boiler needed replacing. From the moment I got in touch with Super Efficient they took care of my situation very quickly. They patched up my old boiler on the same day, explained my options, and 2 days later installed a new boiler. Great communication, did what they said they would do, and left my kitchen cleaner than they found it!"
Sandy Verified Checkatrade review
"Within 10 minutes of the team arriving all my carpets were covered in protective film. The plumbers advised me to move the boiler to the loft, which provided extra space. The plumber said, “I know it's a more difficult job, but that's what I would do in my house”. They completed works in 1 day, left the house spotless and took away the rubbish."
Jonathan Verified Checkatrade review
"This month, they fitted a new Vaillant boiler in my elderly relative's flat. The installation went ahead as planned, on-cost, and with the usual knowledgeable, courteous and friendly service. My relative is very happy with her new boiler."

Everything homeowners ask before booking

If your question is not here, use the form or give us a call and we will come straight back to you.

How long does a Vaillant boiler installation take?
Most straight swaps are completed in a single day. If your install needs a system change, a new flue route or extra pipework, we will tell you before you book so you know exactly what to expect.
How does the 10-year warranty work?
Every Vaillant boiler we fit comes with a 10-year manufacturer warranty covering parts and labour. We are Vaillant approved installers, so we register the guarantee with Vaillant on your behalf after the install. You do not need to do anything.
Are the two free services really included?
Yes. Your next two annual boiler services are included at no charge with every installation. We will get in touch when each one is due, so your warranty stays valid without you having to remember.
Do you need to visit before quoting?
Not usually. We quote remotely from a few details about your current setup, which means you get a fixed price the same day rather than waiting a week for a survey. If anything about your property needs eyes on it, we will say so up front.
Which Vaillant boiler is right for my home?
It depends on the size of your property, how many bathrooms you have and where the boiler needs to sit. We fit the full Vaillant range including the ecoTEC pro, ecoFIT pure, ecoTEC plus and ecoTEC exclusive, and we will recommend the right one when we quote.
Can I pay in instalments?
Yes, instalment options are available. Tell us when you enquire and we will include the payment options alongside your fixed price.
Are you Gas Safe registered?
Yes. Every engineer who works on your boiler is Gas Safe registered, and we are Vaillant approved installers. We are also Constructionline Gold, CHAS, SMAS Worksafe, Acclaim and PQS accredited.
Which parts of London do you cover?
We install across North, East, Central, South East and West London. Send us your postcode and we will confirm coverage along with your fixed price.
