What Sugplumb does

Sugplumb Ltd. is a private, family-run plumbing, heating, and renewable energy installer founded in 2008 by Stuart Sugden and headquartered in Aboyne, Aberdeenshire, serving homeowners, businesses, and community groups across the north east of Scotland. The company installs and maintains a broad portfolio of low-carbon and conventional heating systems — air source and ground source heat pumps, hybrid heating systems, solar PV with battery storage, solar thermal, gas and oil boilers, mechanical ventilation heat recovery (MVHR), and underfloor heating — complemented by general plumbing, private water supply work, and annual servicing contracts. Its engineering team of 11 holds the UK sector certifications required for this work (Gas Safe, MCS, RECC, SNIPEF) and sources equipment from major manufacturers including CTC, Mitsubishi Electric, Daikin, Worcester Bosch, and SolarEdge.

Sugplumb operates a direct, sales-led go-to-market: free on-site surveys and consultations feed custom quotations for installation projects, while a recurring maintenance and servicing book provides ongoing revenue. The company is one of only two OVO Energy renewable installation partners in Scotland and is listed on the Energy Saving Trust installer finder, both of which act as top-of-funnel referral channels. Pricing is quote-based and not publicly disclosed, with customers able to access Home Energy Scotland grants of up to £7,500 and other finance packages through the company. Multi-year award recognition (Heating Installer Awards regional winner 2019, 2020, 2025; HPM Awards Heat Pump and Hybrid Installer of the Year 2024; Grand Designs Magazine feature) supports brand credibility in the regional market. In August 2025, Sugplumb extended its model through a new local franchise partnership with OVO Energy in Aberdeenshire, and in October 2025 it delivered its largest documented commercial contract — a six-unit cascade air source heat pump system for the Camphill Wellbeing Trust in Aberdeen. The business remains wholly owned by its founder, with no external funding, no subsidiaries, and no disclosed acquisitions.

Products and services

• Air Source Heat Pumps Heat pump systems that extract warmth from outdoor air to heat homes via radiators, underfloor heating, or hot water cylinders; effective in cold climates down to -20°C and combinable with Solar PV and battery storage.
• Ground Source Heat Pumps Heat pumps that transfer heat from pipes buried in the ground via borehole or horizontal loops to heat a home or hot water cylinder; suitable for properties with outdoor space.
• Hybrid Heating Systems Integrated systems combining a gas or oil boiler with an air source heat pump, using smart technology to automatically select the most energy-efficient fuel source based on prices, outdoor temperatures, and indoor heat demand.
• Gas Boilers Installation and replacement services for gas boilers, offering systems tailored to customer needs for reliable performance and safety.
• Oil Boilers Fitting, replacement, and servicing of oil boilers for efficient and reliable heating solutions in residential and commercial properties.
• Solar PV Solar photovoltaic panel installations that convert sunlight into electricity for homes and businesses, available with or without battery storage and electric car charging, with flexible roof, wall, ground, and in-roof mounting options.
• Solar Thermal Solar thermal hot water systems that use collectors to absorb the sun's radiated energy and heat fluid circulating through a sealed circuit into a hot water cylinder, providing a consistent hot water supply year-round.
• Underfloor Heating Highly efficient radiant and convection heating system installed beneath floors, providing consistent temperature distribution; ideally paired with air source, ground source, or solar PV.
• Mechanical Ventilation Heat Recovery (MVHR) Ventilation system that extracts stale air from bathrooms and kitchens and reintroduces filtered fresh outside air into living spaces while recovering up to 95% of heat typically lost through conventional ventilation.
• General Plumbing Services Comprehensive plumbing services including routine repairs, new installations, private water supplies, and full system maintenance for gas boilers, oil boilers, heat pumps, solar thermal, and plumbing systems in residential and commercial properties.
• Heat Pump and System Servicing Annual servicing and maintenance for both air and ground source heat pumps, including glycol level checks, electrical component inspection, drainage assessment, and performance optimization by qualified engineers.
• Finance and Grant Funding Advisory Assistance with finance packages and grant funding applications (including Home Energy Scotland grants of up to £7,500 for heat pumps) to help customers afford renewable energy and heating improvements.
