Getting Started with Your Boiler Installation Replacing or installing a combi boiler online can feel overwhelming.
Here’s a clear, step-by-step guide to make the process smooth, informative, and even a little enjoyable.
1. Why Online Quotes Aren’t the Whole Story Many heating companies promise instant boiler pricing online.
While that’s convenient, it can’t account for: Unique pipework layouts Age and condition of existing plumbing Building regulations or loft restrictions When complexity creeps in, you’ll need a free physical survey to ensure your final quote reflects real-world conditions.
2. Book a Free Installation Survey Before you commit to any boiler: Schedule the survey with your preferred installer. Walk through your home together, pointing out unusual pipe runs or tight spaces.

Go with the engineer who listens, not the one who’s just rushing home. Common Boiler Safety Questions Below are answers to the most frequent safety and installation queries in a clear, engaging Q&A.
Q1: Are boilers dangerous?
Gas leaks are serious—but modern boilers are packed with safety features, including: Room-sealed combustion systems Overheat thermostats Pressure relief valves Oxygen depletion sensors A simple reset often fixes minor glitches.
For anything more, always call a Gas Safe engineer.
Q2: Can I sleep in the same room as my boiler?
Yes—if it’s room-sealed. That means: Air intake comes from outside. Combustion gases vent outdoors.
With both functions performed externally, a bedroom boiler poses no greater risk than any other appliance.
Q3: Is it OK to install a boiler in the loft?
Absolutely, provided you: Fit a secure access ladder Ensure frost protection and pipe insulation
Maintain sufficient clearance for servicing Loft placements can free up kitchen or utility space—just factor in winter temperatures.

Frost-protection device on the boiler. Pipe insulation to prevent freeze-ups.
Q7: Where does the flue go? Flue positioning must avoid re-entry of exhaust gases: Keep 30–60 cm from windows or doors.
Maintain specified clearances from corners and boundaries. Route through an exterior wall or roof.
How can I hide my boiler in my bedroom?
An easy way to hide the boiler is to cover it with a small curtain.
You will not have to look at the boiler every day, but it will still be accessible. Choose such a fabric for the curtain that complements the room.
Can you put a fridge next to a boiler?
Ensure good ventilation behind your fridge or freezer so that air can easily flow of the grill behind.
It is just liked a car's radiator and needs airflow to efficiently get rid of the heat.
Do you need planning permission to move a boiler?
Planning permission is not normally required for installation or replacement of a boiler or heating system if all the work is internal, though if you live in a listed building you should check with your local planning authority.
Technical Roles and Regulations Plumber vs. Gas Safe Engineer
Plumber: Handles radiators and pipework; cannot service the boiler itself.
Gas Safe Engineer: Qualified to work on the boiler and gas supply.
Always verify Gas Safe registration before any installation.
Planning Permission and Fire Safety Planning permission: Rarely needed for internal boiler replacement—check only if you live in a listed building.
Fire doors: Required on stairwell doors but not in standard boiler cupboards.
