A gas and heating company who understands the standards required in premium London residential projects — and has the qualifications and track record to back it up.
DGN GAS works alongside architects, luxury developers and interior designers across London on new build and high-end renovation projects. Our team understands that on a premium project, the heating and hot water system needs to be specified correctly, installed cleanly and documented properly — with no comebacks that reflect on you.
We bring the technical capability to handle complex multi-system installations — Megaflo unvented cylinders, wet underfloor heating, air source heat pumps, multi-zone air conditioning — alongside the professionalism, documentation standards and communication that premium projects demand.
Boiler installations, Megaflo unvented cylinders, wet underfloor heating, air source heat pumps, multi-room air conditioning. Gas Safe registered and F Gas qualified — the full range of qualifications needed for modern premium residential projects.
On premium projects, protecting finished surfaces and leaving the site in the condition we found it is non-negotiable. We take this seriously on every job — regardless of size.
Gas Safe certificates, Building Regulations notifications for unvented cylinder installations, manufacturer warranty registrations — all documentation completed correctly and issued promptly. No chasing required.
We turn up when we say we will. We communicate clearly when schedules need to change. We understand that on a development project, one unreliable trade affects everyone else.
When you refer or specify DGN GAS, we understand that reflects on you. We treat every referral accordingly — the standard of work on a referred project is the same as any other.
We remain available to the end client after project completion — for questions, adjustments and annual servicing. A long-term relationship with your clients, built on work you specified.
