Our Boiler Replacement Process in St Leonards
Some homes are best served by a straight like-for-like swap, where the new boiler goes in the same position as the old one. Others benefit from converting to a different type of boiler at the same time. We talk both options through with you and carry out whichever suits your property.
A good boiler replacement starts before any tools come out. We look at your existing boiler, how your home uses heating and hot water, and what is driving the change, then recommend a new model that genuinely fits. You get a free, no-obligation quote for the work before anything is agreed.
Signs to Look Out For in St Leonards
- Rooms that never quite reach the temperature set on the thermostat
- Replacement parts for your model becoming harder to source
- Pressure that needs topping up again and again despite repeated fixes

Boiler Replacement FAQs
Answers to common questions about boiler replacement in St Leonards and across East Sussex.
Do you carry out boiler replacements outside St Leonards?
Yes, we cover the whole of East Sussex. HJA Heating Ltd is based in Eastbourne and replaces boilers in Hailsham, Seaford, Hastings, Bexhill, Uckfield, Heathfield, Polegate, and Battle, as well as St Leonards and the villages in between.
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.
Can I get a quote before deciding anything?
Yes. Quotes are free and carry no obligation. We survey your existing setup, talk through the options, and give you a fixed price with no hidden fees, so you can take your time deciding whether to go ahead.
Will you remove my old boiler?
Yes. Removing the old unit is part of the job. We disconnect the existing boiler safely, take it away, and leave the work area tidy once the new boiler is in place.
Which boiler brands do you fit as replacements?
We fit replacement boilers from Vaillant, Worcester Bosch, ATAG, and Ideal. Our engineers know these brands well and will recommend the model that best matches the size of your home and your heating habits.
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.
