Frequently Asked Questions


Which areas do you operate in?

Throughout Hertfordshire, including Hemel Hempstead, St Albans, Kings Langley and Abbot’s Langley. 

How long does it take to service a boiler?

There are two types of service. The basic service includes a safety check, flue gas analysis, condensing trap cleaning, and, if present, magnetic filter cleaning. This takes about one hour.

Our comprehensive service includes the above plus main heat exchanger cleaning and replacing all necessary seals. This takes around 2.5 hours.

Should I get my boiler repaired or buy a new one?

This is one we’re asked a lot, and in many cases, the answer is that it’s best to buy a new one, particularly if your boiler is over 20 years old, as it should actually save you money. For more details, please see our boilers page

Can you dispose of my old boiler?

Yes, it’s all part of the service that we dispose of it responsibly and efficiently.

Why do I need to get my gas pipes replaced?

Many gas pipes more than a few years old measure just 15mm and however good condition they may be in, Gas Safe regulations state that all new gas boilers should have 22mm pipes, or even bigger in some cases.

Is there a call-out charge?

Yes, for fault-finding and emergencies. This is £70 during normal days, 9am to 5pm, and £90 outside these hours and at weekends and on bank holidays. There is no call-out charge for installations.

How long does it take to arrive in an emergency?

Usually we can get to you within an hour.

What makes of boiler do you install?

All leading brands – for details, see our boilers page

How do I know if my central heating needs a power flush?

Tell-tale signs include if it’s often switching itself on or off or making banging, knocking or whistling noises, cold spots on the radiators and general poor heating performance.

Is my property suitable for underfloor heating?

If it’s relatively new, yes, thanks to strict regulations about airtightness and insulation. Many older properties are still suitable as well, however.

What guarantees do you offer?

All our work comes with a one-year guarantee, and many new appliances and other installations have much longer guarantees.

Are you Gas Safe registered?

Yes, all of our engineers are fully qualified and registered.
