Partner application FAQs

Who is this recruitment section for?

Self-employed engineers, specialist subcontractors and trade businesses can express interest in the wider UK Gas Plumbers partner network. Choose a trade that matches your actual capability and describe your coverage.

Does this mean Heat Pump Installers London offers every listed customer service?

No. The recruitment directory covers the wider partner network. This domain’s customer services remain air conditioning, heat pumps and the existing HVAC and F-Gas service pages. Recruitment categories are not customer service offers.

Where do applications go?

All applications go to https://app.ukgasplumbers.com. There is no subcontractor application form on this website. Customer quotes and bookings continue through the existing separate booking flow.

Are these advertised vacancies or guaranteed work?

No. These are partner-network expressions of interest, not confirmed jobs, employment vacancies or income guarantees. Acceptance, individual assignments and commercial terms require separate agreement with the network.

What should I include in an application?

Describe your trade experience, competence limits, actual registrations or training, supported equipment, UK travel area and availability. Do not claim qualifications you do not hold. The network confirms any additional evidence or onboarding terms.

Share your skills and coverage

Applications are handled at app.ukgasplumbers.com, not through this site’s customer quote form. Share your trade scope, coverage and availability with the partner network. No rates, payment schedule or acceptance criteria are promised here; confirm them directly before taking on work.
