Service overview

Boiler installation and maintenance

What it is

We install new and replacement boilers and carry out servicing, upkeep and repairs on existing boilers for commercial and domestic properties. Every gas job is carried out by our Gas Safe registered team.

Who it's for

Homeowners, landlords, schools, golf clubs, offices and other commercial premises that need dependable heating and hot water.

When you need it

When your boiler is old, unreliable or inefficient; when it is due for a service; when it breaks down; or when you are refurbishing or changing how the building is heated.

Why use a specialist

Gas work must be carried out by a Gas Safe registered engineer. We are also water hygiene specialists, so we understand how hot water temperatures affect Legionella control. Boiler installations come with a warranty, with terms set out at quote stage, and we carry £5 million public liability insurance.

The risk

What happens when a boiler is neglected

Boilers that are not serviced lose efficiency, use more fuel and are more likely to break down, often when you need them most.

A poorly maintained gas boiler can be unsafe. Unreliable hot water temperatures can also undermine Legionella control in commercial buildings. A breakdown can leave a building without heating or hot water.

Common mistakes we see

  • Skipping annual servicing to save money.
  • Using an unregistered installer for gas work.
  • Choosing a boiler that is the wrong size for the building.
  • Ignoring warning signs such as noises, pressure loss or erratic hot water.
  • Not considering hot water temperature control when replacing a system.

Guide

Choosing, installing and looking after your boiler

A boiler is one of the most important pieces of equipment in any building. It provides heating, and in many systems hot water too. Choosing the right one, installing it properly and looking after it keeps it safe, efficient and reliable for years.

The right boiler depends on the size of the property, how much hot water is used and when, and the existing system. Combination boilers heat water on demand and suit many smaller homes. System and regular boilers work with a hot water cylinder and suit properties with higher hot water demand. In commercial buildings, the system often needs to be sized for peak use, such as changing rooms after a match at a golf club or a busy school day.

Installation must be carried out by a Gas Safe registered engineer. That is a legal requirement for gas work in the UK, and it protects you and the people using the building. Our team is Gas Safe registered and installation, commissioning and handover requirements are confirmed for your system. Boiler installations come with a warranty, with terms set out clearly at quote stage.

Regular servicing keeps a boiler working safely and efficiently. During a service, components are checked, cleaned and adjusted, and any early signs of wear are flagged before they turn into a breakdown. Landlords also have legal obligations around gas safety in rental properties, so keeping servicing up to date matters.

There is also a water hygiene angle. In buildings with stored hot water, the boiler and cylinder need to keep water hot enough to control Legionella. As water hygiene specialists, we consider this when installing or adjusting heating and hot water systems, alongside the heating requirements.

We install, service and repair boilers across Luton, Bedfordshire, Hertfordshire, Milton Keynes and the surrounding counties, for both commercial and domestic clients, 8am to 8pm, seven days a week.

Boilers for homes, landlords and businesses

Homeowners want reliable heating and hot water at a sensible running cost. We help you choose a boiler that suits your home and how your household uses hot water, then install it to a high standard.

Landlords need boilers that are safe, reliable and easy to maintain between tenants. Regular servicing helps keep rental properties compliant and reduces breakdowns that lead to tenant complaints.

Schools, golf clubs and offices need heating and hot water that cope with peak demand. We consider usage patterns, stored hot water temperatures and Legionella control when installing or adjusting systems.

Whatever the property, every gas job is carried out by our Gas Safe registered team, backed by £5 million public liability insurance and a warranty on installations, with terms stated in your quote.
