New gas boiler installation for homes across St Albans, fitted by a Gas Safe registered engineer. Fixed quotes before any work starts, and the job guaranteed once we’re done.

BOILER INSTALLERS EXPERT
If your boiler is over ten years old, breaking down often, or costing more to run each winter, replacing it is usually cheaper in the long run than keeping it going. We’ll talk through your home’s heating and hot water needs, recommend a boiler that fits your household properly (not the biggest or most expensive one), and fit it without cutting corners.
Most straightforward swaps are done in a single day. If you’re also updating your central heating system or need radiators replaced at the same time, we can plan that in as one job rather than two separate call-outs.

BOILER INSTALLATION GUIDE
A few signs it’s worth getting a boiler looked at rather than repaired again: it’s over 10-12 years old, needs an engineer more than once a year, takes a while to heat the house, or your gas bills have crept up without a change in usage. Older boilers also tend to run at 70-80% efficiency compared to 92%+ on a new A-rated model, so the running cost difference is real.
None of this means you need a new boiler right away. Regular boiler servicing and a valid Gas Safety Certificate can keep an older system going safely for longer. We’ll give you an honest view either way, not just a quote for the most expensive option.

COMMON WARNING SIGNS
If any of these sound familiar, it’s worth getting your boiler looked at before winter makes the decision for you.
Constant repairs could mean it's time to replace your boiler.
Older boilers are often less efficient and more expensive to run.
Cold radiators or inconsistent temperatures may indicate your boiler is struggling.
Banging, whistling or gurgling sounds shouldn't be ignored.
Leaks around your boiler can lead to further damage if left untreated.
If your boiler is over 10–15 years old, replacing it may be more cost-effective than repairing it.

ThanksPosted on Google Deepak M.BTrustindex verifies that the original source of the review is Google. I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving. What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler. Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.

FAQ
It depends on the boiler you choose and how much pipework is involved, so we don’t quote a fixed number until we’ve seen your home. You’ll always get a free survey first, followed by a written fixed quote with no hidden extras added later.
Most homes in St Albans suit a combi boiler, since it’s compact and doesn’t need a separate tank. Larger households with more than one bathroom often do better with a system boiler. We’ll recommend the right type after seeing your water pressure and household size, not before.
A straightforward like-for-like combi swap is usually done in a single day. If pipework needs moving or you’re converting from a different system type, it can take two to three days. We’ll confirm the timescale in your written quote before any work starts.
Yes. Taking away and disposing of your old boiler is included as standard, so you don’t need to arrange separate removal or pay an extra fee for it.
Yes. Every new boiler comes with a manufacturer’s warranty, typically between 5 and 12 years depending on the model, and we handle the registration for you so you don’t have to deal with the paperwork.
Yes. All boiler installation work is carried out by Gas Safe registered engineers, which is a legal requirement for any gas work in the UK. You can always ask to see an engineer’s Gas Safe ID card before work begins.
