What's involved
A typical boiler installation project in Sheerness follows these steps:
- Site survey to assess existing pipework, flue route, and gas supply adequacy
- Removal of the old boiler and safe disposal (including draining the system if needed)
- Fitting the new boiler, connecting gas, water, and condensate pipework
- Installing or repositioning the flue to meet current Building Regulations
- System flush, commissioning, and registering the warranty with the manufacturer
What to check before hiring
- Gas Safe registration: It is a legal requirement for anyone installing a gas boiler to be on the Gas Safe Register. Always check the engineer's ID card and verify it online.
- Manufacturer accreditation: Many boiler brands offer extended warranties (up to 12 years) only when the installation is carried out by an approved installer. Ask which brands the engineer is accredited with.
- Building Regulations notification: Boiler installations are notifiable work. A Gas Safe registered installer can self-certify, avoiding the need for a separate Building Control application.
- Written quote and warranty terms: Get a fixed-price written quote that includes the boiler model, flue, controls, system flush, and warranty registration. Confirm who handles warranty claims.

Frequently asked questions
How long does a boiler installation take in Sheerness?
A straightforward like-for-like combi boiler replacement usually takes one day. If the installation involves changing the boiler type (for example, from a conventional system to a combi) or relocating the boiler to a new position, allow two to three days.
Do I need planning permission for a new boiler in Sheerness?
In most cases, no. Boiler installations are covered by Building Regulations rather than planning permission. However, if your property is listed or in a conservation area, restrictions on external flue positions may apply. Your installer should advise.
What type of boiler is best for a 3-bed house?
For most 3-bed houses with one bathroom, a combi boiler rated at 28-35 kW is sufficient. If you have two or more bathrooms, a system boiler with a stored hot-water cylinder may provide better performance during peak demand.
