Boilers & Heating Engineers

Your boiler is an essential part of your home for family wellbeing and also within your business premises. It has to be in consistent peak condition to ensure continuous safety, warmth and comfort

Full Installation

We install modern heating systems from standard pumped two-pipe systems to luxurious under-floor heating solutions.

Boiler Replacements

Boilers need to be replaced periodically as they eventually become unsafe and inefficient. OPC Building Services Ltd will assess your boiler’s condition, give you an honest appraisal and only when necessary, help you decide on a new boiler.


OPC Building Services Ltd installs, services and repairs all kinds of radiators, including traditional, designer, and vertical. Today, we understand that radiators can sometimes be about more than just heating but can make a real design statement in a room.

Regular servicing is essential for efficiency and safety.

Boiler Gas Safe Certification

We have qualified engineers able to provide certification for all gas appliance installations and servicing on both domestic and non-domestic systems.


OPC Building Services Ltd has a 12 month guarantee on all work carried out by our professional team.

Central Heating Systems

Supplied - Installed - Guaranteed

Central heating installation is a cost and labour intensive endeavour. There are many tasks needed to be done—from fitting the pipework throughout your house, placing radiators to be ready for use in your rooms, and of course installing the boiler.

It is recommended to have it done by a professional installer due to the complex nature of central heating.

When it comes to central heating installation – whether you’re planning to replace your old heating system or install one from scratch, you can have peace of mind as OPC Building Services Ltd have arranged some great deals with the world’s biggest and best manufacturers.

That’s how we can supply and fit every component to the highest standards of performance and design. Our huge range of central heating installation systems means there’s one that’s perfect for your lifestyle.

Gas Safety Certificate

We have qualified engineers able to provide certification for all gas appliance installations and servicing on both domestic and non-domestic systems.

The safety checks needed annually for gas appliances are:

  • Domestic: Landlord or homeowner gas safety record (CP12)
  • Non-domestic: Gas installation safety report (CP17)

An annual CP12 is a legal requirement for landlords of tenanted properties. Although it’s not a legal requirement for homeowners, it is needed for most boiler manufacturer warranties, and usually for home insurance policies too.
