Green Energy Installs UK — EV Chargers, Solar and Heat Pumps as a Business Opportunity for Tradespeople (2026)

The UK's net zero target, phased boiler replacement policies and the explosive growth of electric vehicles have created three distinct, high-demand install markets — EV chargers, solar PV and heat pumps. For qualified tradespeople willing to invest in the right certifications, each one offers better day rates, longer jobs and a customer base that is actively driven by government grant deadlines.

This article covers who can install each technology, what certifications are required, what the work pays and what you need to know to position your business as a green energy installer.

Why green installs are growing

Three policy levers are pushing residential and commercial customers towards green installs faster than at any previous point:

• Net zero 2050. The UK government's legally binding commitment keeps long-term demand structurally high.
• Boiler replacement policy. New-build homes can no longer be connected to the gas grid, and future announcements on phasing out gas boiler sales in existing homes continue to drive customers towards heat pumps before deadlines land.
• EV growth. There are over 1.5 million registered EVs in the UK. Almost every homeowner with a driveway who buys one will need a home charger. The petrol and diesel new-car ban from 2035 means this pipeline extends for years.
• Grant schemes create urgency. The Boiler Upgrade Scheme, the OZEV Electric Vehicle Homecharge Scheme and the Smart Export Guarantee all give customers a financial reason to act now rather than wait. Grant-funded work is also easier to close because the customer's upfront cost is significantly reduced.

All three technologies are still in relatively early residential penetration. That means the installers who build expertise now will be the ones with the reputation, reviews and pipelines when volume really ramps.

Section 1: EV charger installation

Who can install

EV charger installation is primarily an electricians' market. You need to be qualified to the 18th Edition wiring regulations (BS 7671) and, to access the OZEV grant, you must be registered as an OZEV-approved installer. Approval is obtained by registering with an OZEV-recognised certification body — NICEIC, NAPIT and BSI all run EV charge point installer schemes.

The OZEV Electric Vehicle Homecharge Scheme

The OZEV EVHS currently offers a £350 grant towards the cost of a home charger unit for eligible homeowners and renters. The grant goes to the customer and is administered through the approved installer, meaning you apply on their behalf as part of the job. Customers are motivated to use approved installers specifically because it unlocks the grant.

What the work pays

A standard domestic 7kW home charger installation typically takes one to two days. Labour costs run £400–£800 depending on the complexity of the cable run and consumer unit work required. The charger unit itself adds a further £300–£600 to the customer's bill, though some installers supply this themselves at a margin. A competent electrician can complete two to three straightforward installs per week once the workflow is established.

The market opportunity

With 1.5 million-plus EVs already registered and new sales accelerating, the addressable market is large and geographically spread. Jobs are relatively quick, straightforward and repeatable, making EV charger installation a high-volume add-on for electricians. There is also a growing upgrade market as earlier adopters move from slower 3.6kW units to 7kW or 22kW chargers.

Section 2: Solar PV installation

Who can install

Solar PV installation requires MCS certification (Microgeneration Certification Scheme). This is non-negotiable if your customers want to claim Smart Export Guarantee (SEG) payments or access certain finance products. MCS certification requires relevant electrical qualifications as a foundation, completion of an approved training course and ongoing accreditation.

Getting MCS certified

MCS is a meaningful investment. Training courses typically cost £2,000–£5,000 and annual accreditation fees run around £1,000. For an electrician targeting the domestic solar market, this is recoverable within a handful of jobs, but it requires genuine commitment upfront. The benefit is that MCS certification acts as a barrier to entry that protects margins — not every competitor will make the investment.

What the work pays

A typical domestic installation is a 4kW system — roughly 12 to 16 panels depending on the panel specification. Labour for a 4kW system runs £1,500–£3,000 and the panels, inverter and balance of system materials add a further £3,000–£5,000. Customers expect a turnkey quote covering everything. Jobs take one to three days depending on roof complexity and whether battery storage is being added.

The Smart Export Guarantee

The SEG allows homeowners to get paid by their energy supplier for excess electricity exported back to the grid. Rates vary by supplier and tariff, currently ranging from around 2p to 15p per kWh. SEG payments are only available if the installation is MCS-certified, which is a strong selling point when closing solar quotes — particularly with customers who are motivated by energy prices.

The market

Residential solar demand has been driven sharply upward by high energy prices. Rural customers with larger roof areas and no gas connection are particularly motivated buyers. Battery storage add-ons — often quoted as a package with panels — significantly increase job value and give customers grid independence.

Section 3: Heat pump installation

Who can install

Heat pump installation requires both F-Gas qualification (because heat pumps use refrigerants) and, to access the Boiler Upgrade Scheme grant, MCS certification. The typical route is a qualified heating engineer or plumber who adds F-Gas certification and completes specific heat pump training. Courses are available through BPEC, OFTEC and CIPHE, typically running two to five days and costing £500–£1,500.

The Boiler Upgrade Scheme

The BUS currently provides a £7,500 grant for eligible air source heat pump installations. This is the most significant grant in the green install market and it substantially changes the customer's cost calculation. As with OZEV, the grant is only accessible through MCS-certified installers, which means certification directly unlocks the customer pipeline.

What the work pays

A typical 6–12kW air source heat pump for a three-bed house takes two to four days to install. Supply and fit prices run £8,000–£15,000 before the BUS grant. After the £7,500 grant is applied, the customer pays £500–£7,500 — a compelling cost reduction that closes jobs. Heat pump engineers command £400–£600 per day, reflecting the specialist skill set and the complexity of the installation.

Design requirements

Heat pumps require correct sizing to perform efficiently, and this involves a formal heat loss calculation for the property. Unlike boiler swaps, which are largely like-for-like, a heat pump installation requires an understanding of the building's fabric, insulation, emitter sizing and flow temperature targets. Some installers sub the design out to specialist heat loss consultants; others complete the design in-house once trained. Either way, getting this right is critical — an undersized or oversized heat pump will perform poorly and damage your reputation.

The market opportunity

Around 1.7 million boilers are replaced in the UK every year. Heat pump penetration in existing homes is still a fraction of that figure. Early-mover heating engineers who build the skills, the MCS accreditation and the marketing position now are placing themselves ahead of a market that will accelerate significantly as boiler phase-out policy tightens. The first-mover advantage in a local area is real — customers searching for heat pump installers in their postcode will find whoever has been trading longest, with the most reviews.

Considerations across all three

• Higher upfront training cost, faster payoff. Each of these markets requires a certification investment, but the job values are substantially higher than standard domestic work. EV charger certification can pay back within weeks; MCS for heat pumps within a handful of jobs.
• Premium day rates. Green installs attract specialist rates. Heat pump engineers regularly earn £400–£600 per day. Solar and EV charger work similarly commands a premium over standard residential electrical or plumbing work.
• Marketing differentiation. Positioning your business specifically around green installs — on your website, Google Business Profile and van livery — sets you apart in a market where most trade businesses still market themselves generically. Customers searching for an OZEV-approved charger installer or MCS heat pump engineer have high intent and are ready to book.
• Grant urgency closes jobs. Government grant schemes change. When customers know a grant is time-limited or under review, they act faster. Building your sales process around clearly communicating available grants — and handling the application paperwork — removes friction and accelerates decisions.

The infrastructure shift to net zero is not a short-term trend. For UK tradespeople willing to invest in the right qualifications, the green install market offers better margins, repeat customers and a structural tailwind that standard domestic work does not.
