How to start an air source heat pump business

Being an air source heat pump installer might seem like a niche profession, but its a growing industry. If you're already installing air source heat pumps, why not think about starting your own business?

Being an air source heat pump installer means that your skills are going to grow in demand.

ASHPs are now one of the best ways to equip buildings with low-carbon heat. Demand continues to grow due to the government’s plan to install 600,000 a year by 2028.*

If you’re looking to progress your career in this exciting (and growing) sector, read on as we take you through everything you need to know to get things up and running.

Why start out as an ASHP business?

Homeowners are also interested as they can lower their energy bills and carbon footprint. ASHPs help with sustainable heating and hot water.

So, there’s no better time to start an air source heat pump business and make the most of the growing opportunities.

For example, in 2023 there were just under 50,000 searches on our website for jobs relating to air source heat pumps.**

Starting your own business will mean you setting your own hours, having the power to hire and choosing which jobs you take on.

Do I need qualifications to start an air source heat pump business?

Installing heating systems requires a great deal of technical understanding. As a result, qualifications related to heating and engineering will probably be necessary. Especially if you want to come across as reliable and competent.

Here are some options if you’ve not studied before:

  • Level 2 Diploma in Plumbing and Heating
  • Level 3 Diploma Building Services Engineering
  • T Level in Building Services Engineering for Construction
  • Building Services Engineering Installer intermediate apprenticeship
  • Building Services Engineering craftsperson advanced apprenticeship

Seeing as ASHPs are a low-carbon product, you should also complete the Accredited Microgeneration Certification Scheme (MCS).

Becoming MCS certified shows that you are a competent installer in the renewable heating industry, which will encourage potential customers to hire your services.

How do I start an air source heat pump business?

First things first – registration

For legal reasons, you’ll first have to register your business with HMRC.

When doing so, you’ll also need to choose how you want set up your business. You can opt for a sole trader or limited company structure, and your choice will depend on what suits you best.

  • Sole trading is easier to set up, but you’ll be held personally responsible for any debt or losses you incur
  • Limited companies give you better financial protection but can prove more expensive and time-consuming

Considering your business legal structure is important before you set out. You’ll also need to plan ahead.

The importance of planning

Going in blind is not the smartest move. If you want your business to thrive, you should put together a clear plan first that outlines the nuts and bolts of your service along with your target market.

When shaping your service, try to include a unique selling point so you can stand out from the competition. For example, you could:

  • Offer emergency repairs as part of your air source heat pump business
  • Provide round the clock call outs that allow you to charge a premium rate

Remember ASHPs are fairly new, so there’s bound to be some teething problems at first – use your trade knowledge and experience to cover all eventualities.

Once you’ve figured out what you’re offering, the next step is to identify your target audience.

If your existing experience lies in domestic plumbing installations, set your sights on homeowners as the main source of new business. Make sure you also consider your location – are there enough homes in the area with enough free space required to fit an ASHP? Or is it mainly high-rise apartments?

By answering these questions in your business plan, you’ll cut out unprofitable opportunities and also save on time and fuel costs when travelling between jobs.

Getting the right trade cover

Covering all scenarios is crucial for a start-up, which is why you’ll need insurance in case anything goes wrong.

Here are the types you should consider for your ASHP business:

  • Public liability insurance – Covers for claims made against you by members of the public. Without it, your business could end up facing hefty legal fees and compensation costs
  • Professional indemnity insurance – This will protect you in the event a client is left unhappy with your work
  • Income protection insurance – If something happens that leaves you unable to operate, this will protect you from loss of income
  • Tools insurance – Covers the cost of replacements if your tools are lost or damaged and it’s not your fault

As an air source heat pump installer, like with any trade profession, it is so important to get the right cover.

In the unlikely event that something unexpected happens, you need the peace of mind from knowing you have the right cover in place.

How do I manage my business finances?

It’s crucial to consider your finances carefully. Installing air source heat pumps is still relatively new as a profession, so the ‘going rate’ may vary across different parts of the country.

Make sure you do your research and understand what’s considered a fair return for your time and knowledge.

Cash flow

Once you’ve set up a business account, you’ll want to keep a close eye on everything that goes in and out.

By tracking your cashflow you’ll be able to gauge how well your business is doing, which of course is vital for growth and stability.

Having a good idea of your profit margins also means you can make financial changes before they have a detrimental effect.


Ingoings and outgoings aren’t the only thing you’ll need to monitor. Taxes also must be documented on a regular basis if you’re going to keep on top of things.

You’ll have different taxes to file based on the business structure you choose, so it’s best you do some research and find out which apply to you.

If you’re struggling to find the time to do your taxes or you can’t seem to wrap your head around them, you could always hire an accountant for help.


Being an air source heat pump installer is still quite a niche trade. But be considerate. Premium rates may generate more profit, but it can lead to clients looking elsewhere and you losing out on opportunities.

That said, be careful not to set your prices too low or you may find yourself struggling to stay in the black.

How do I grow an air source heat pump business?

ASHPs are backed by several government grants and incentive schemes – these are great way to get your business off the ground.

Some are aimed at homeowners, so look into each one and determine if you can use them to your advantage. Examples include:

  • Boiler Upgrade Scheme – Open to people in England and Wales to cover part of replacing fossil fuel heating systems
  • Home Energy Scotland – Scottish homeowners can get an interest-free loan from the government to pay upfront costs of ASHP installation

Digital marketing

Signing up to Checkatrade will boost your profile instantly, as your business becomes readily available to over three million monthly site users. Plus, you also receive free marketing materials to help develop your reputation as a leading air source heat pump installer.

Set up a website for your business

That way potential customers have a point of contact and source of information online. You can easily create a website yourself using a simple template, or pay a web designer to set up your site for a one-time fee.

Hiring a professional to design your website will grant you a more impressive layout that may be more convincing to customers who visit your site. Once your site is all set up, you could look at investing in web ads to give your business an extra boost.

Don’t forget the power of social media

Setting up a business profile across different platforms allows you to reach new audiences and interact with potential clients. Plus, you can showcase your work through videos and images to promote your different services.

Just be careful to choose the right platform – some will be geared towards consumers while others are aimed at professionals and businesses.

Print marketing

While print marketing may not have the same reach as digital strategies, it’s still really effective for drumming up local business.

You can distribute flyers or leaflets around your local area and focus on properties that fall in your target market. If you’re looking to attract homeowners, you can go door-to-door in surrounding neighbourhoods.

For commercial businesses, it’s worth putting together a short brochure to explain how you can help. Once you’ve got some jobs under your belt, you can begin adding in sector-specific case studies – e.g. ASHP installation at an office block or manufacturing facility.
