Prince Edward Island has the most explicit geothermal-specific well regulations of any Atlantic province, with the 2021 Water Act and Well Construction Regulations naming geothermal wells directly and establishing clear permit thresholds. Oil heat is widely used across the island, and the federal Oil to Heat Pump Affordability Program is the only active geothermal incentive right now — the provincial EfficiencyPEI rebate program has been paused since April 2026 while the province finalizes 2026–2027 funding. Our directory lists 7 verified geothermal contractors serving Charlottetown, Summerside, and communities across all three counties.

Top Prince Edward Island cities for geothermal contractors
PEI's relatively small geographic footprint means most verified contractors can serve the full island. Coverage is concentrated in Charlottetown and Summerside, with contractors also serving rural areas in Queens, Prince, and Kings Counties.

Prince Edward Island geothermal incentives in 2026
PEI's provincial geothermal rebate program is currently paused. The only active geothermal-relevant incentive for island homeowners in 2026 is the federal Oil to Heat Pump Affordability Program, available to oil-heated homes meeting income requirements.
- Oil to Heat Pump Affordability Program (OHPA) — up to $15,000 for oil-heated homes. Federal program, co-delivered in Prince Edward Island. Ground-source heat pumps are eligible (must meet CSA C448 standard). Household income must be at or below the area median; home must currently be heated with oil. PEI co-delivers with a provincial top-up that can bring the total to $15,000 where provincial funding remains available — confirm current availability with a participating contractor at application time.

EfficiencyPEI's Energy Efficient Equipment Rebates — which previously offered up to $4,000 for geothermal heat pumps in standard residential installations and up to $7,500 for income-qualified households — were paused as of April 15, 2026, while 2026–2027 funding is being finalized. The program is expected to resume; check our incentives tool or the EfficiencyPEI website for updates before installing.
The Canada Greener Homes Grant and Canada Greener Homes Loan are both closed to new applications.
Prince Edward Island geothermal regulations & well-drilling rules
PEI has the most geothermal-explicit well regulations in Atlantic Canada. The governing framework is the Water Act, R.S.P.E.I. 1988, Cap. W-1.1 (in force June 2021) and the Well Construction Regulations, EC507/21 (W01-1-4). The regulations name geothermal wells directly — the government's licensing page states: "Any person who undertakes in the drilling, construction or reconstruction of a water or geothermal well, needs a Well Driller's License."
Who must be licensed: All well drilling must be performed by or under the direct supervision of a licensed Well Driller (individual licence, $200 initial, $100 renewal, 24-month term) and overseen by a licensed Well Contractor (company licence, $500 initial, $250 renewal, 24-month term). An applicant without the required 1,500 hours of PEI drilling experience may receive a licence restricted to geothermal wells only until the threshold is met.
Horizontal-loop systems are excluded from the regulations (s. 2): an opening made for a horizontal-loop geothermal system is not classified as a well under the Well Construction Regulations. Horizontal closed-loop systems do not require a licensed driller permit or well construction report under provincial regulations.
When a Well Permit is required for geothermal: A $25 Well Permit is required for a closed-loop geothermal system when either (a) more than five wells are being drilled for a single system, or (b) the wells' collective depth exceeds 250 metres for a single system. A permit is also required regardless of system size when drilling in a Schedule A Restricted Area — mapped zones across Prince County, Queens County, and Kings County where groundwater protection is heightened. Systems at or below the 5-well and 250 m thresholds in non-restricted areas need a licensed contractor and driller, but no permit.
Closed-loop well construction requirements (Schedule B): boreholes must be grouted continuously to ensure full contact between the ground heat exchanger and the borehole annulus. Heat-transfer fluid must meet Schedule B standards. Direct exchange (DX) systems require cathodic protection per Schedule B. A well construction report must be filed with the Minister within 60 days of completing each borehole.
Open-loop systems have additional requirements: discharge lines cannot connect to sewage or wastewater systems; return wells must accept reinjected water without overflow; backflow prevention is required where the supply well serves both domestic and open-loop purposes.
Use the permits tool to check whether your project location falls within a Schedule A restricted area before you start planning.
Prince Edward Island climate and ground conditions
Prince Edward Island has a humid continental climate moderated by its island location. Charlottetown averages roughly 4,200–4,400 heating-degree days — colder than Nova Scotia's south shore but milder than mainland New Brunswick or NL. Winter temperatures regularly reach -20°C during cold snaps, giving geothermal a clear advantage over air-source heat pumps that lose efficiency at low outdoor temperatures.
PEI's geology is primarily red sandstone and sedimentary bedrock — softer than the granite found in parts of Nova Scotia or NB. Vertical closed-loop systems are common, though the softer substrate means drilling is generally faster than in hard-rock provinces. Ground temperatures at loop depth typically run 8–10°C, sufficient for efficient winter heating. Horizontal systems are also viable on properties with adequate yard space and are unregulated under provincial rules, which can simplify the project for suitable sites.
Oil and propane heat are both common on the island, and energy costs here tend to be higher than mainland averages. With the OHPA program available to oil-heated homes and the provincial EfficiencyPEI rebate expected to resume, the near-term economics of geothermal on PEI are worth modelling before the fall heating season.
