Hales & Coultas Heating and Plumbing

What Hales & Coultas Heating and Plumbing does

Hales & Coultas Heating and Plumbing is a UK-based trade services company operating from Scunthorpe, North Lincolnshire, as the trading name for Ongo Heating & Plumbing within the Ongo Homes group. It delivers commercial and domestic heating, plumbing, electrical, and renewable energy services, including commercial boiler installation/servicing/repair, catering equipment maintenance, water hygiene and Legionella testing, landlord services, domestic boiler installation/repair/servicing, central heating, gas appliance servicing, consumer unit upgrades, EV chargers, smart home integration, air source heat pumps, and solar/battery storage (the latter via the acquired Trent Valley Electrical Services subsidiary). Customers include private businesses, local authorities, landlords, schools and academies, care homes, GP and dental practices, social housing providers (notably the parent Ongo group), charities, and domestic homeowners, served under long-term maintenance contracts, short-term contracts, and one-off jobs through an exclusively direct, field-sales-led model.

The company's core technology stack is field-service oriented: qualified engineering staff executing installations and maintenance, supported by a stack of sector accreditations (Gas Safe, Oftec, MCS, RECC, Constructionline, CHAS, APHC, Trustmark, Worcester Bosch Gold, Anglian Water Approved, Disability Confident Level 2). A differentiated layer is the deployment of 165 AI-enabled remote monitoring devices across renewable heating installations, which collect operational data for trend analysis, diagnostics, and faster repair response. The business is owned by Ongo Partnership Limited, with profits reinvested into local communities, and it employs approximately 25 staff, expanded to roughly 33 following the September 2025 acquisition of Trent Valley Electrical Services. Headcount is small, revenue is not publicly disclosed, and the company operates as a regional, multi-trade services provider rather than a software or platform business.
