Boiler Replacement FAQs
Answers to common questions about boiler replacement in Denton and across East Sussex.
Why choose HJA Heating Ltd for a boiler replacement in Denton?
We are a local Eastbourne-based company rated 4.8 from 246 reviews, with Gas Safe engineers, honest repair-or-replace advice, fixed transparent pricing, and coverage across the whole of East Sussex, including Denton.
Do you replace boilers for landlords as well as homeowners?
Yes. HJA Heating Ltd replaces boilers for both homeowners and landlords across East Sussex. Whether it is your own home or a rental property, the same Gas Safe engineers and the same fixed, transparent pricing apply.
How long does a boiler replacement take?
It depends on the job. A straightforward like-for-like swap is usually quicker than a conversion to a different boiler type. We plan the work in advance and keep the time your home is without heating as short as possible.
How much does a boiler replacement cost?
We provide a free, no-obligation quote with fixed, transparent pricing and no hidden fees. The exact figure depends on the boiler you choose and the work involved, but the price we agree is the price you pay.
Is a new boiler cheaper to run than my old one?
An old, inefficient boiler often costs more to run than it should. A modern energy-efficient replacement is designed to make better use of the fuel it burns, which is one of the main reasons customers choose to upgrade.
Should I keep repairing my old boiler instead of replacing it?
Sometimes, yes. If a repair is the sensible option, we will say so. When faults keep recurring or the boiler is beyond economical repair, replacement usually works out better in the long run, and we will explain why honestly.
