The Heat Pump Market in 2026

Few trades have a demand curve as clean as this one. Heat pumps sit at the intersection of three forces that are not going away: building decarbonisation targets, volatile gas prices, and government money aimed squarely at electrifying heating. Analyst estimates for the global heat pump market in 2025 cluster around $94.5 billion, with individual reports spread from roughly $83 billion to $108 billion depending on how they treat commercial chillers and hot-water units (Grand View Research, 2025). MarketsandMarkets is more aggressive, sizing the market at $83.27 billion in 2025 and forecasting $162.64 billion by 2030 at a 14.3% CAGR (MarketsandMarkets, 2025). The exact figure matters less than the fact that every serious forecaster expects the installed base to roughly double this decade.

For a business plan, the number a lender actually cares about is not the global market – it is how much of your local market is winnable. A single busy installer will complete somewhere between 60 and 150 domestic jobs a year. Against a UK town of 40,000 homes still burning gas, or a US county replacing failing air conditioners with heat pumps, that is a rounding error of local demand. The scarcity is not customers; it is trained, certified, well-organised installers who quote accurately and turn up. Your plan should make that argument explicitly rather than leaning on the headline market size.

Air-source, ground-source or air-to-water – pick your lane

Most guides talk about "heat pumps" as one thing. They are not, and the model you specialise in changes your entire cost base, sales cycle and margin. A credible plan states which of these you lead with and why:

The brand mix reinforces the point. Consumers increasingly ask for named kit – Daikin (the global leader, with the Altherma range), Mitsubishi Electric (the Ecodan benchmark), Bosch, Vaillant and Samsung – and in the UK, Octopus Energy has moved from retailer to manufacturer-installer with its Cosy 6 unit. A single-installer business does not compete with Octopus on price; it competes on the survey quality, the emitter design and the after-care that a national roll-out cannot match street by street. Your plan should name the two or three manufacturers you will accredit with, because that decision drives your training, warranty terms and stock.

Quick Answers Buyers Search For

These are the questions prospective customers and lenders type into Google before they call you. Answering them cleanly in your plan (and on your website) shortens the sales cycle.

How much do heat pump installers charge per install?

In the US, a straightforward residential air-source install runs $4,200 to $7,900, with ductwork and higher-capacity units pushing the top end (Angi, 2026). In the UK, an air-source install is usually £7,000 to £13,000 before the £7,500 Boiler Upgrade Scheme grant is deducted, so the customer's out-of-pocket number is what they remember. Ground-source and commercial systems are several multiples higher because of loop excavation or borehole drilling.

How profitable is a heat pump installation business?

Gross margin on a well-priced job sits around 40–50%. Net margin, after the van, the technician, insurance, software and the founder's own time, is realistically 5–15%. Profit is made on the survey desk, not the tools: an accurate heat-loss calculation stops you from under-quoting, and a tight second-visit rate protects the margin you booked.

Is now a good time to start a heat pump business?

The policy tailwind is real. The UK's Boiler Upgrade Scheme runs to 31 March 2028, Germany's Building Energy Act now pushes 65% renewable heating on new systems, and heat pumps have outsold gas furnaces in the US for several years running. The 2026 wrinkle is that the US federal Section 25C tax credit expired on 31 December 2025, so a US plan should lean on utility rebates and running-cost savings rather than the federal credit that older guides still quote.

Do you need a licence to install heat pumps?

Yes – and the specifics differ by country, which we cover in full below. The short version: refrigerant-handling certification is legally required everywhere (EPA 608 in the US, F-gas in the UK and EU), and grant access in the UK depends on MCS certification. Skipping these is not a shortcut; it is what makes you uninsurable and locks your customers out of the money they came for.

Who Buys a Heat Pump

"Homeowners" is not a segment – it is a crowd. The installers who quote profitably know exactly which buyer they are built for, because the sales cycle, the objections and the average job value are wildly different across the three real markets. Your plan should pick a lead segment and treat the others as expansion.

Retrofit homeowners (the volume market)

These are owner-occupiers replacing an ageing gas boiler or oil system, usually prompted by a breakdown, a renovation or an energy bill that finally stung. They are grant-motivated in the UK – the £7,500 Boiler Upgrade Scheme is often the deciding factor – and rebate-motivated in the US. They compare two or three quotes, worry about disruption and radiator changes, and value a surveyor who explains flow temperatures in plain English. Average job value is modest but volume is high, and a happy retrofit customer is your best referral engine.

Landlords and property portfolios (the contract market)

Tightening minimum energy-efficiency standards are pushing landlords to upgrade heating across multiple units. This buyer thinks in spreadsheets, not comfort: they want a predictable per-property price, a fast turnaround between tenancies and clean compliance paperwork. Winning one portfolio can be worth twenty retrofit jobs, and it smooths the lumpy cash flow that kills young installers. The trade-off is a longer, more relationship-driven sales cycle and tighter payment terms.

Commercial and public sector (the high-value market)

Schools, care homes, offices and social housing bodies run decarbonisation programmes with real budgets, often part-funded by public grants. Contracts here run from tens of thousands into six figures, but they demand commercial references, method statements, and the capacity to handle air-to-water and cascade systems. Most installers grow into this market rather than starting in it – but naming it as a Year 2–3 expansion in your plan signals ambition to a lender.

The strategic point for your business plan: quantify how many of each buyer exist in your service radius, which converts fastest, and which produces the best margin. A plan that says "we will target homeowners and businesses" is weak. A plan that says "we will win 70 retrofit jobs and two landlord portfolios in Year 1 within a 25-mile radius of Leeds, then add commercial in Year 2" is fundable.

What It Costs to Launch

A heat pump installation business is capital-light compared with a factory, but heavier than a laptop service business – the van and the certifications are unavoidable. Expect $45,000 to $180,000 in the US, or £15,000 to £90,000 in the UK, with the spread driven almost entirely by how many vans and technicians you launch with. A sole trader converting an existing service van sits at the bottom; a two-crew operation buying vehicles and stock sits at the top.

Cost breakdown

• Service van (bought and fitted out): $25K–$55K (£15K–£40K) – usually the single biggest line
• Refrigerant recovery, gauges, vacuum pump & brazing kit: $4K–$12K (£3K–£9K)
• Certification & training (EPA 608 / F-gas + MCS): $500–$3K US · £1.5K–£6K UK
• Insurance (public liability, employer's, tools): $2K–$6K/yr (£1.5K–£4K/yr)
• Heat-loss survey & design software licences: $600–$2.5K/yr (£500–£2K/yr)
• Branding, website & first-job marketing: $3K–$10K (£2K–£8K)
• Working capital (stock + 3 months of overhead): $10K–$40K (£6K–£25K)

Funding routes

In the US, the SBA 7(a) loan is the workhorse for trade businesses – up to $5M, terms up to 10 years for equipment and working capital, and lenders who understand the HVAC cash cycle. Our bespoke plan service formats projections the way SBA lenders expect to see them. In the UK, the government-backed Start Up Loan offers up to £25,000 per founder at 6% fixed with free mentoring, and it stacks well with asset finance for the van, which keeps your cash free for stock. Green-specific grants and low-carbon funds appear regularly at regional level; a plan that names the schemes you will pursue reads far stronger than one that hand-waves at "available grants". You can start from our free business plan template and layer the financials on top.

Van, Tools & Kit Checklist

Underestimating the kit is the fastest way to blow the startup budget. This is the working list a new installer typically buys before job one, with realistic price bands. Prices assume mid-range professional tools, not the cheapest option that fails on site.

On the back office, most installers run a field-service platform to schedule jobs, dispatch crews and invoice on site. ServiceTitan, Housecall Pro, Jobber and Workiz dominate in the US; UK installers often pair a job platform with dedicated heat-loss tools such as Heat Engineer. Budget a per-seat monthly subscription and build it into your overhead line rather than treating it as an afterthought.

How the Money Works

Heat pump revenue is job-based, so your model is really about throughput per crew and how well you protect margin on each install. The healthiest installers layer three streams: new installations (the headline revenue), service and maintenance contracts (predictable, high-margin recurring income), and repair/callout work (fills the gaps between installs).

Installations carry a 40–50% gross margin once you subtract the heat pump unit, cylinder, emitters, pipework and labour. The recurring service side – annual checks and F-gas leak inspections – carries far higher margin because there is little material cost, and it is the part of the business that lenders and buyers value most because it is not dependent on winning the next quote.

Worked example: a two-van UK retrofit installer

The lesson buried in those numbers: growing from six to eight jobs a month does more for net profit than shaving material costs, because your fixed overhead is already paid for. That is why the operations section of your plan should obsess over survey-to-install conversion and crew scheduling, not just headline pricing. US operators run the same maths in dollars, with per-install values in the $4,200–$7,900 residential band and much larger commercial contracts pulling up the average.

Labour & Technician Pay

Labour is your largest recurring cost and your biggest constraint – you cannot grow faster than you can hire and certify. Ground your financial model in real wage data rather than guesswork. In the US, the Bureau of Labor Statistics puts the median wage for heating, air-conditioning and refrigeration mechanics and installers at $59,810 a year ($28.75/hour) as of May 2024, with the top 10% earning more than $91,020 (US Bureau of Labor Statistics, 2024). Heat-pump-specialised installers average around $48,460, though experienced techs in high-demand states earn well into the $70K–$105K range.

Two planning implications follow. First, build your quotes so loaded labour (wages plus employer taxes, insurance and downtime) recovers 30–40% of each job value – that is where HVAC labour typically lands, and quoting below it is how installers quietly go broke while looking busy. Second, factor in a training pipeline: an apprentice on lower pay who you certify over 12–18 months is cheaper and more loyal than perpetually poaching finished techs at a premium in a tight labour market.

Certification & Legal Requirements

This is the section that separates a heat pump plan from a generic HVAC plan. Refrigerant rules and grant access are specific, non-optional, and directly affect which customers you can serve. Get them into the plan early – lenders and, in the UK, grant administrators check.

United States

• EPA Section 608 certification – legally required to purchase and handle refrigerant. Type II or Universal covers most heat pump work; the exam costs roughly $20–$150.
• State HVAC / mechanical contractor licence – required in most states (rules vary widely; some states have none, others demand an exam plus documented experience and a surety bond).
• NATE certification – voluntary but respected; a useful trust signal on your website and quotes.
• Section 25C tax credit – note the change: the 30% (up to $2,000) federal credit expired on 31 December 2025. Sell on utility rebates and running-cost savings, not the expired credit.

United Kingdom

• F-gas certification – legally required to work on sealed refrigerant circuits (typically via City & Guilds / Refcom routes).
• MCS certification – the gateway to the £7,500 Boiler Upgrade Scheme grant; without it, your customers cannot claim, so it is effectively mandatory for retrofit work. Setup is usually via an MCS umbrella body.
• Boiler Upgrade Scheme (Ofgem): £7,500 for air- and ground-source heat pumps (up to £9,000 for off-gas-grid oil/LPG homes), running to 31 March 2028. The EPC requirement was removed in April 2026, widening eligibility.
• Electrical competence (Part P) and public liability insurance (customers and commercial clients expect it).

Germany (a third market worth planning for)

• Building Energy Act (GEG / "Heizungsgesetz") – pushes new heating systems toward 65% renewable energy, making heat pumps the default replacement.
• BEG subsidy – funds up to 70% of a heat pump installation for eligible households, creating strong installer demand.
• SHK trade qualification – the recognised heating/plumbing trade credential expected of installers accessing subsidised work.

Sales, Marketing & Operations

A heat pump business lives or dies on two operational numbers: how many qualified enquiries you generate, and what share of your surveys turn into signed installs. The marketing plan feeds the first; the operations plan protects the second. Lenders read both closely because they explain how the revenue forecast is actually achieved.

Where the enquiries come from

• Local search and Google Business Profile: most heat pump buyers start with "heat pump installer near me". Ranking locally, with genuine reviews and photos of finished jobs, is the highest-ROI channel for a young installer.
• Grant-aware messaging: lead with the customer's out-of-pocket number after the £7,500 grant or local rebate, not the headline price. It reframes the whole conversation and cuts the "too expensive" objection.
• Manufacturer and platform leads: accrediting with a brand like Daikin, Vaillant or Mitsubishi routes warm enquiries to you, and installer networks (including those built by energy retailers) feed verified jobs to certified fitters.
• Referrals and reviews: a retrofit customer who is warm in January tells their street. Systematise the ask – a follow-up at commissioning and a review link – rather than hoping it happens.

The survey-to-install workflow

The single most important operational discipline is never quoting without a proper heat-loss survey. The sequence that protects your margin looks like this: qualify the enquiry on the phone, carry out a room-by-room heat-loss calculation on site, design the emitter and cylinder specification, then issue a fixed quote you can stand behind. Skipping straight to a ballpark price is how installers win the job and lose the money – the overrun on undersized emitters or unexpected pipework comes out of your margin, not the customer's.

From there, operations is about scheduling crews so vans are never idle, holding enough stock to avoid a stalled job, and commissioning cleanly so the system runs at the low flow temperatures a heat pump needs to be efficient. A tight second-visit rate is worth more to your bottom line than any single marketing tactic, because every callback is unpaid labour eating a job you already booked. Build your field-service software, stock policy and commissioning checklist into the plan as deliberately as your sales funnel.

Finally, plan the capacity ceiling honestly. One crew can physically complete only so many installs a month, and you cannot grow revenue past that without hiring and certifying another technician – which takes months, not weeks. Mapping that hiring pipeline against your revenue ramp is exactly the kind of operational realism that separates a plan a lender believes from one they quietly discount.

Mistakes That Sink Installers

Most heat pump businesses that fail do not fail on demand. They fail on avoidable operational errors that eat the margin they thought they had. Address each of these in your plan and you are ahead of most competitors on your street.

• Quoting before a full heat-loss survey. A guessed sizing leads to an under-quoted job or an under-performing system. Do the calculation first, every time – it is the single biggest protector of margin.
• Registering with MCS too late. In the UK, customers expect the £7,500 grant. If you are not certified when they are ready to buy, you lose the job to someone who is. Start the process before you launch, not after.
• Under-specifying emitters. Heat pumps run at lower flow temperatures than gas boilers. Skimp on radiator or underfloor upgrades and the home runs cold, the reviews turn bad, and the callback erases your profit.
• Chasing every job instead of a niche. Retrofit, new-build and commercial are different businesses with different sales cycles. Pick one to lead with; a scattered plan reads as an unfocused one to any lender.
• Treating refrigerant rules as red tape. EPA 608 and F-gas compliance are what keep you insurable and legal. Cutting corners here is an existential risk, not a saving.

The Numbers Your Forecast Must Prove

A heat pump business plan without a financial forecast is a brochure. Lenders, whether it is an SBA 7(a) underwriter or a UK Start Up Loan assessor, are testing whether the story in your narrative holds up when it is turned into cash flow. A few figures do most of the persuading:

• Installs per crew per month. This is the engine of the whole model. State it, defend it with your survey conversion rate, and show what happens when you add a second crew.
• Average job value and gross margin. Split by system type if you serve more than one – a plan that blends a £9,000 air-source job with a £40,000 ground-source job into one "average" is hiding something a lender will find.
• Break-even month. With one or two vans, most disciplined installers reach break-even somewhere between month 6 and month 12. Show the month and the assumptions behind it.
• The cash gap. You pay for the heat pump unit, cylinder and labour before the customer pays you in full, and in the UK the grant is redeemed on a lag. Model the working-capital trough – it is usually deeper than founders expect and is the most common reason young installers stall.
• Recurring service revenue. Even a modest book of annual service contracts changes the risk profile of the business, because it is income that does not depend on winning the next quote. Lenders and future buyers price it at a premium.

Our $300/£250 Research + Content and $1,000/£800 Bespoke packages build this as a 5-year Excel model – income statement, cash flow, balance sheet and break-even – so the narrative and the numbers tell one coherent story rather than contradicting each other on page nine.

Heat Pump Terms Worth Knowing

Investors and grant assessors notice when a founder uses the trade's language correctly. These are the terms that come up most often in a heat pump plan:

• SCOP (Seasonal Coefficient of Performance): how many units of heat the pump delivers per unit of electricity across a year. A SCOP of 3.5 means 3.5kW of heat for every 1kW of power – the number that underpins your running-cost sales argument.
• Flow temperature: the temperature of the water the pump sends to the emitters. Heat pumps run most efficiently at low flow temperatures, which is why emitter sizing matters so much.
• Emitters: the radiators or underfloor loops that release heat into the room. Under-sizing them is the classic cause of a "cold" heat pump and bad reviews.
• Heat-loss survey: the room-by-room calculation of how much heat a building loses, which determines the correct pump size. Quoting without it is the cardinal sin of the trade.
• MCS: the UK Microgeneration Certification Scheme – certification that opens up the Boiler Upgrade Scheme grant for your customers.
• F-gas / EPA 608: the refrigerant-handling rules (UK/EU and US respectively) that make you legal and insurable to open a sealed circuit.
• Cascade system: multiple heat pumps working together for larger commercial loads – the technical step-up from residential into contract work.
