Gas Heating Solutions

Exceptional gas heating solutions through expert design and installation

At DCR, we deliver exceptional gas heating solutions through expert design and installation, and industry-leading aftercare tailored to both domestic and commercial clients across central London.

Our experienced engineers and in-house design team work closely with consultants, architects, and homeowners to create bespoke heating and hot water systems. These range from high-efficiency unvented cylinders in private residences to complex, high-capacity systems of 500kW or more for schools, large residential blocks and commercial premises. Every system is engineered for optimal energy efficiency, long-term performance, and complete peace of mind.

While our team is fully trained to work with all major boiler brands, we proudly specify Viessmann systems where possible due to their unrivalled reliability, efficiency, and innovation. We continually invest in manufacturer-led training and advanced system knowledge to stay ahead of evolving technologies and regulations.

Our fully qualified gas engineers operate 365 days a year, providing not only expert installation but also ongoing servicing, annual maintenance reminders, and rapid-response breakdown support with priority access for our existing clients.

Gas & Oil Boiler FAQs

How often should my boiler be serviced?

A gas or oil boiler should be serviced at least once a year. Regular servicing ensures safety, efficiency, and compliance with regulations. DCR offers an annual reminder service, to help you keep your system in warranty, running smoothly and to help reduce the risk of costly breakdowns.

Are gas and oil boilers being phased out in the UK?

The UK government is encouraging businesses and homeowners to switch to low-carbon heating, but gas and oil boilers are still widely used and legal to install. DCR can maintain your current boiler while also advising on renewable options like heat pumps, solar, and hybrid systems when you’re ready to transition.

What are the signs my boiler needs replacing?

Frequent breakdowns, rising energy bills, unusual noises, or visible leaks are signs it may be time for a replacement. DCR can carry out a detailed assessment and recommend whether repair or replacement is the most cost-effective solution.

How much does it cost to install a new gas or oil boiler?

The cost of a new boiler installation depends on the size of your building, the complexity of the system, and any additional upgrades required. Every system we install is bespoke, designed for long-term efficiency, reliability, and compliance. Choosing DCR means investing in quality, expertise, and a heating system that’s built to last.

Are gas and oil boilers safe?

When installed and maintained correctly by Gas Safe or OFTEC registered engineers, gas and oil boilers are very safe. DCR’s engineers are fully accredited and carry out comprehensive safety checks with every service or installation.

Why should I choose DCR for my gas or oil boiler system?

At DCR, we combine technical expertise with a customer-first approach. From design and installation to servicing, breakdowns and long-term maintenance, we deliver reliable heating solutions tailored to your needs. Our Gas Safe and OFTEC accredited engineers give you complete confidence in safety, compliance, and efficiency.
