PHD Mechanical offers premium boiler services for breakdowns, repairs, and new installations. We also carry out repairs and maintenance on all types of boilers, gas appliances, and plumbing around London & surrounding areas.


We work closely with both commercial and domestic clients. So, if you are thinking of installing a new heating system/boiler for your home or company, please ensure that the installer you choose is accredited with recognised professional bodies. Check that they are registered with Gas Safe and OFTEC as this is a compulsory requirement. PHD Mechanical Installers have all the necessary qualifications and accreditations, and you can see the full list here.

Repairs and Maitenance                                                          

We provide a maintenance service, once the installation or repairs have been carried out by us. We automatically send out reminders to make sure your equipment is serviced and certified annually, we recommend this, to keep your boiler working safely and efficiently.
Our long-standing relationships with industry leaders has garnered us a high reputation among our clients, and we continue to provide the best alternatives for high-quality, energy-efficient boilers that will improve the efficiency of both homes and businesses.

Gas Safety Certificates                                                                                          

By law, as a landlord or the main responsible person for your company, it is your responsibility to get a gas safety certificate (CP12) annually. However, PHD Mechanical will provide you with annual gas safety certificates for your gas appliances. We'll be able to advise on any remedial work required or quote to replace/install, as required, if they don’t pass.
