Gas Boiler Installation: Frequently Asked Questions
If you’re considering a gas boiler installation, you likely have many questions about the process. Here are some of the most frequently asked questions to help you make an informed decision.
What is a gas boiler and how does it work?
A gas boiler is a heating system that uses gas to create heat and hot water for your home. It works by burning gas to heat water, which is then pumped around your home to provide central heating and hot water.
What are the different types of gas boilers?
The main types of gas boilers are combi boilers, regular boilers, and system boilers. Combi boilers are the most popular as they provide both heating and hot water in one compact unit.
How long does a gas boiler last?
A gas boiler can last between 10-15 years, depending on how well it is maintained and how frequently it is used.
How much does a gas boiler installation cost?
The cost of a gas boiler installation can vary depending on the type of boiler, the size of your home, and the complexity of the installation. We do not quote a figure without seeing the property, because the honest answer depends on your house rather than on an average. Every new boiler installation we do is quoted free of charge, in writing, at a fixed price — and that price is what you pay.
Do I need planning permission to install a gas boiler?
No, you do not need planning permission to install a gas boiler. However, if you live in a listed building or conservation area, you may need to obtain permission from your local authority.
Can I install a gas boiler myself?
No, gas boiler installation must be carried out by a Gas Safe registered engineer who has the necessary qualifications and experience.
How often should I service my gas boiler?
It is recommended to service your gas boiler once a year to ensure it is working safely and efficiently.
How can I make my gas boiler more efficient?
You can make your gas boiler more efficient by ensuring it is well-maintained, regularly serviced, and by installing a smart thermostat to control your heating more efficiently.
What should I do if my gas boiler breaks down?
If your gas boiler breaks down, you should contact a Gas Safe registered engineer to come and assess the problem. Do not attempt to fix the boiler yourself.
Will I be without heating and hot water?
For most of the working day, yes. A straight swap is usually a single day; converting from a regular or system boiler to a combi is more like two, because the cylinder and loft tank come out and the pipework is reworked. If a job is going to run overnight, we tell you before we start rather than at five o’clock.
Do I need to be at home?
Someone needs to let us in and be there at handover so we can walk you through the controls. Clear access to the boiler, the meter and the stopcock saves time — if the boiler lives in a cupboard full of coats, emptying it beforehand gets us started sooner.
Who registers the boiler and notifies Building Control?
We do, both. The manufacturer’s warranty registration and the Gas Safe notification are handled for you, and the Building Regulations compliance certificate follows in the post. Keep it with your house paperwork; a buyer’s solicitor will ask for it one day.
What guarantee do I get?
The manufacturer’s warranty covers the boiler itself, and its length depends on the model you choose. Our workmanship carries a separate 12-month guarantee on installations (90 days on repairs). Nearly every manufacturer requires an annual service to keep their warranty valid — ours is a flat £95 + VAT, and we will remind you when it is due.
Is it worth upgrading to a new gas boiler?
If your current gas boiler is over 10 years old, upgrading to a new, more efficient boiler can save you money on your energy bills and improve the overall performance of your heating system.
