Electric Boiler Installation Expert
An electric boiler is often the simplest option for flats, park homes or properties without a mains gas connection. There’s no flue to fit and no gas safety certificate needed, which makes installation quicker and less disruptive than a gas boiler swap.
Running costs are usually higher than gas per unit of heat, so we’ll talk you through realistic bills before you commit, and compare it honestly against alternatives like a heat pump where mains gas genuinely isn’t an option.
Electric boilers often need a supply upgrade, which our boiler wiring engineers can check first. If you would rather move to a low carbon system, ask about an air source heat pump, or browse all our heating services in St Albans.


Electric Boiler Installation Guide
If your property has no gas supply, or extending one would be expensive, an electric boiler is usually the most straightforward heating option. They also suit smaller flats where a compact unit and no flue matter more than running costs.
For larger homes wanting to move away from gas, a heat pump is often more efficient long-term. We’ll compare both honestly based on your household size and usage.



COMMON WARNING SIGNS
Book a check if you notice any of these. Most problems are quicker and cheaper to fix when they are caught early.
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.

Sharif bhai did a very good job in my property. He fitted the shower properly and fixed the leak issue. He checked everything carefully and made sure there was no more leaking after the work finished. He was polite, professional, and helpful. The work was neat and clean, and the shower is now working very well. I am happy with his service and I would recommend Sharif bhai to others for plumbing work.Posted on 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.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
