New and replacement boilers
Start with the household, not just the appliance.
A new installation and a boiler replacement both need a plan for the whole heating system. The way you use rooms, baths and showers matters alongside the condition of existing equipment and the space available. If a fault has prompted the enquiry, our boiler repair service starts with diagnosis before a decision on replacement.
Home boiler installation is part of our gas and heating services. If an older fireplace system is involved, our back boiler removal and servicing page explains the separate considerations before equipment is changed.
Boiler options
Combi, system or regular: choose the arrangement that fits.
- Combi boilers
- A combi provides heating and heats water on demand without a separate hot water cylinder. The incoming water supply and likely demand from taps and showers need checking, particularly where several outlets may be used together.
- System boilers
- A system boiler works with a separate hot water cylinder. Stored hot water can suit households with demand at several outlets, but cylinder space, capacity and the existing installation need consideration.
- Regular boilers
- Also called heat-only or conventional boilers, these commonly work with a cylinder and separate feed and expansion arrangements. Retaining or changing this type of system depends on the existing layout and the proposed heating and hot water requirements.
For background on the differences, read the Energy Saving Trust's boiler guide. Suitability still depends on your home and the proposed installation.
Before choosing the equipment
Assess the supply, connections and controls.
- Heating and hot water use
- The property, heat demand and how the household uses hot water help determine a suitable boiler. Bigger is not automatically better; the choice should follow an assessment rather than simply match the old appliance rating.
- Pipework and the existing system
- The gas supply, water supply, radiators, cylinder where present and heating pipework need review. Any changes or system preparation should be identified in the proposed scope.
- Position, flue and controls
- A suitable boiler position needs access for maintenance, a compliant flue arrangement and an appropriate condensate route. Controls must suit the boiler and heating system, with any required changes discussed before installation.
Installation and commissioning
From assessment to a checked, working system.
Discuss and assess
Share your postcode, current boiler details and heating or hot water concerns. We assess the property and installation, then discuss suitable equipment and whether to retain or change the system arrangement.
Agree the installation
The quote should identify the boiler, connections, controls, system preparation and any additional work. Agree access, making-good arrangements and how interruptions to heating and hot water will be managed.
Install the agreed equipment
The existing appliance is safely disconnected where required and the new boiler and agreed connections installed. Gas work must be undertaken by an appropriately qualified Gas Safe registered engineer.
Commission and hand over
The installation is inspected, tested and commissioned in accordance with the appliance instructions and applicable requirements. We explain the controls and discuss ongoing care, with the relevant records and notification arrangements.
Scope and cost
What affects the installation quote?
- Boiler and system choice
- The appliance specification, hot water arrangement and whether the work is a straightforward replacement or a change of system affect the proposed installation.
- Location and connections
- Relocating a boiler or changing the flue, condensate route, gas supply or heating pipework can add work. Access and making good should be discussed as part of the quote.
- Preparation and controls
- The condition of the existing system, cleaning or remedial work, controls and any cylinder changes influence the scope. Check what is included rather than compare appliance prices alone.
Checks, records and ongoing care
The completed work needs appropriate checks of the gas installation, flue, boiler operation and controls, with commissioning records and the relevant Building Regulations notification. Keep the documentation with your property records. GOV.UK guidance on home building work explains the approval and compliance process.

Boiler installation questions
Which type of boiler is right for my home?
That depends on heating demand, hot water use, available space, water supply and the existing installation. Combi, system and regular boilers offer different arrangements. We assess these factors before discussing suitable options.
Can you replace my boiler in its existing position?
Possibly, but the location, flue, access, connections and applicable requirements need checking. Keeping the same position does not mean every existing connection can automatically be reused.
Can I change from a back boiler to another heating system?
A different heating arrangement can be considered following assessment. The associated fire, flue, pipework and hot water provision need review together. Removal and replacement are distinct parts of the work and should be agreed before proceeding.
Will existing radiators and controls need replacing?
Not necessarily. Their condition and compatibility with the proposed boiler need assessment. Any required changes or system preparation should be explained in the scope rather than assume the whole system must be replaced.
What documentation should I keep after installation?
Keep the appliance instructions, completed commissioning record and relevant Building Regulations compliance documentation. Ask how notification will be handled and how the documents will be provided. These serve a different purpose from a routine landlord gas safety record.
What affects boiler installation cost?
The boiler type, installation position, existing connections, system preparation, controls and any additional work influence the cost. Contact us with property and appliance details so we can discuss an assessment and quote without assuming a standard price fits every home.
