Gas Boilers: A Complete Guide for UK Homes

Heating your home efficiently is a priority for every household, and gas boilers remain one of the most popular choices across the UK. They’re reliable, cost-effective, and compatible with modern central heating systems. Whether you’re replacing an old unit or installing a new one, choosing the right gas boiler ensures comfort and energy savings.

At TradePlumbing, we supply a wide range of gas boilers from trusted brands, designed for both performance and affordability.

What Is a Gas Boiler?

A gas boiler heats water for your central heating system and domestic hot water supply using natural gas or LPG (liquefied petroleum gas). It’s the heart of your home’s heating system, distributing heat to radiators, underfloor heating, and taps.

Types of Gas Boilers

Not all boilers are the same. Here are the three main types available in the UK:

Combi Boilers

  • Heats water on demand, eliminating the need for a hot water cylinder.

  • Compact and ideal for smaller homes or flats.

  • Highly efficient and cost-effective.

System Boilers

  • Requires a separate hot water cylinder but no loft tank.

  • Perfect for homes with multiple bathrooms and higher hot water demand.

Regular (Conventional) Boilers

  • Works with a hot water cylinder and cold water storage tank.

  • Suitable for older heating systems and large properties.

At TradePlumbing, we offer gas boilers for every type of system.

Why Choose a Gas Boiler?

Gas boilers continue to be a favourite among UK homeowners because they offer:

  • Affordable Running Costs – Natural gas is one of the cheapest heating fuels in the UK.

  • Reliable Performance – Proven technology with modern efficiency upgrades.

  • High Energy Efficiency – Modern condensing boilers can achieve over 90% efficiency.

  • Compatibility – Works seamlessly with existing radiators, underfloor heating, and thermostats.

Gas Boilers and Energy Efficiency

Energy efficiency is key when selecting a boiler. Modern condensing gas boilers recover heat from exhaust gases, reducing energy waste and cutting your heating bills. Look for boilers with:

  •  High ErP Ratings

  •  Smart Controls

  •  Weather Compensation Technology

What Size Boiler Do You Need?

Boiler size depends on your property and hot water usage:

  • Small Homes (1 Bathroom): 24–27kW Combi Boiler

  • Medium Homes (2 Bathrooms): 28–34kW Combi or System Boiler

  • Large Homes (3+ Bathrooms): 35–42kW System or Regular Boiler

Always consult a heating engineer before making a final decision.

Gas Boiler Installation & Safety

Important: Gas boilers must be installed by a Gas Safe registered engineer. Proper installation ensures safety, compliance with UK regulations, and peak efficiency.

Regular servicing is also essential for:
