Follow the Q for...peace of mind

Simple really, time and again we make our customers happy. Qualis has a proven track record in providing quality heating services to customers throughout Scotland. Not to brag, but we've got a GREAT REPUTATION.
Out team care and it really shows in each job we do. From the moment you pick up the phone, we've got you covered. With our 5* RATED SERVICE there's really no reason to look elsewhere.

  • Why Qualis?

    Qualis is big enough to cope but small enough to care. We're focused on delivering quality installations from only the best heating engineers. We work across Scotland with a focus on the Central Belt, Perth & Kinross and surrounding areas.
    We have many happy customers across the country. We're WHICH approved & highly rated Trustpilot (4.7.) This shows our commitment to providing quality installations.
    We are also a company that cares, partnering with Clyde1 and Cash for Kids on their schools initiative.

  • Will it be FREE? 

    The Government set up the Energy Company Obligation Scheme (ECO) in order to lower greenhouse gas emissions. This is done by improving the energy efficiency of households and installing energy-efficient upgrades. Generally, you will need to own your home, receive benefits and have a gas boiler over 8. To maximise the level of funding you will be entitled to, we will also require you to insulate your underfloor. 
    A lot of companies will advertise this as a FREE boiler initiative but in reality, there will normally be some sort of contribution to pay. Qualis will work with you to ensure you receive the maximum funding available to you. That's our promise to you! 
    Once you submit your form, one of our team will be in touch with next steps. If we think you meet the pre-qualifying criteria we will book you in for a home energy assessment. 
    If you wish to proceed and apply for funding through Qualis, we will work with you throughout the process. We will keep you updated along the way in terms of how much you will need to contribute to the overall costs and carry out the installation works.

  • How do I know if I will qualify?

    Typically to qualify for an ECO grant you need to be a homeowner in the UK and receiving benefits but we won't know if your property qualifies until we conduct a home energy assessment and technical survey. 
    The qualification criteria can be as simple as follows.● You are a homeowner (or a private tenant who has never had a central heating system.)● You live in a qualifying property - we carry out an energy assessment on each property. Flats normally don't qualify. 
    It really is that simple. Start the process today, it only takes around 60 seconds to take our pre-assessment eligibility check. 

  • What do I need?

    Part of the service is a FREE energy assessment of your home. This is to make sure that we can fully understand the range of measures that will be available to you. If your property meets the initial assessment we will then conduct a technical survey of your property. 
    Insulation is FREE of charge for eligible parties, but there may be a contribution required for our heating or renewable solutions. 
    You will also need to be on qualifying benefits below. Please take a look at our Eco Scheme Eligibility Page for more info.

Review via Trustpilot, Feb 21

"A refreshingly different heating company. Really helped my partner get heating back into her property following a flood. My partner had a string of rotten luck recently so I was so pleased her boiler was dealt with so quickly. Fantastic service, honest and transparent from start to finish. I would give more than 5 stars if I could."

"Service was amazing from start to finish. Very quick and efficient.The guys who came to our house were great, had underfloor insulation and a new boiler fitted for just £450. Can't fault them and would highly recommend them!"
