New Boiler Costs & Quotes
The right replacement depends on your home, fuel type and existing heating system. We assess the practical options, explain the fitting and installation cost, then provide a clear quotation so you can choose with confidence.
What to consider before choosing a new boiler
Several practical details affect the right boiler and the final price. Your fuel supply, hot-water demand, flue route, heating controls and property layout all matter, so we work through them before recommending equipment or preparing the quotation.
Your fuel supply
If your home uses mains gas, oil or LPG, the replacement options differ. Our Gas Safe or OFTEC-registered engineers recommend equipment suited to the fuel already serving your property.
Your hot-water demand
A combi boiler may suit a smaller household with one bathroom. If several people use hot water at once, we compare a system or regular boiler with a cylinder instead.
The condition of existing pipework
Older pipework, radiators or valves can limit a new boiler’s performance. We check what can stay, what needs upgrading and how those changes affect the quotation.
The flue and condensate route
The boiler needs a suitable flue position and a safe route for condensate drainage. We inspect the proposed location before pricing the installation, especially in older or altered properties.
Controls and future changes
If you plan to alter rooms, insulation or hot-water use, tell us before the survey. We can account for suitable controls and system changes rather than leaving you with an undersized installation.
What the quotation includes
Your written quotation sets out the boiler, required alterations, controls, removal of the old equipment and installation work. We explain the cost before work starts, so there are no surprise charges.
Compare your new boiler options
An inexpensive boiler is not always the lowest-cost choice once fitting, controls and future servicing are included. We compare replacement routes by installation work, running requirements and long-term practicality, so the quotation reflects how your household heats its home.
Like-for-like combi replacement
Your home already has a gas combi boiler, so we first check the flue, gas supply and controls. Keeping the same layout can reduce plumbing changes and keep the fitting cost clearer.
System boiler with cylinder
Your household needs several hot-water outlets at once, so a system boiler and cylinder may suit better. We price the cylinder, controls and any pipework changes alongside the boiler.
Regular boiler replacement
Your home has a hot-water cylinder and cold-water storage tank, so a regular boiler may avoid converting the whole system. We check the loft tank, cylinder and existing pipework before quoting.
Oil boiler replacement
Your property is off the gas grid and uses oil, so we assess the boiler, tank, oil line and flue together. Our OFTEC-registered engineers can identify which existing components affect the installation cost.
What a properly specified boiler installation includes
An accurate new boiler price starts with the parts beyond the appliance. We account for controls, filters, flue work, condensate drainage and alterations needed to connect the replacement safely.
If your existing system is older, the estimate may include pipework, radiators or hot-water changes. We explain the items, separate essential work from optional improvements, and show what’s included before you decide.
Boiler sizing for the home
An oversized boiler can cost more to run and cycle unnecessarily, so we assess the heat demand, room layout and hot-water needs before recommending a model.
The right fuel type
If the property uses gas, oil or LPG, the replacement must suit the existing supply and flue arrangement. Gas work is carried out by Gas Safe engineers, while OFTEC registration covers oil-fired systems.
Hot-water capacity
A combi boiler may suit one home, while another needs a cylinder or alterations to the hot-water system. We explain how each option affects cost, storage space and daily use.
Heating system compatibility
Older radiators or restricted pipework can limit a new boiler's performance, so we identify upgrades that are necessary rather than adding work without explanation.
Controls that suit the household
The quotation can include thermostats, timers and zoning where they improve control. We show what each control does and separate useful upgrades from essential items.
Access and removal included
A boiler in a cupboard, loft or tight utility space can affect labour and installation cost. We allow for safe access, removal of the old appliance and leaving the area tidy.
Safe commissioning
Once the boiler is connected, we test the system, check combustion and confirm the controls operate correctly. We provide the relevant installation and commissioning paperwork.
A quotation you can compare
You receive a written quotation before work starts, with the appliance, labour, materials and any recommended alterations shown clearly. Essential work and optional improvements are listed separately, with no surprise charges.
Questions to ask before choosing a new boiler quote
How can I compare new boiler installation quotes fairly?
Ask whether the quotation covers removal, disposal, controls, flue changes, commissioning and certification. Confirm who will complete the work, what happens if hidden defects appear, and when payment is due.
Will the quoted boiler price change after the home survey?
Usually, the quotation stays unchanged when the survey confirms information provided. If we find concealed defects or essential alterations, we’ll explain the revised cost and seek approval before any work starts.
How is the right boiler size determined for my home?
An oversized boiler costs more to run, while an undersized one may struggle in colder weather. We calculate heat loss, hot-water demand and radiator capacity before recommending the appropriate output.
Is VAT included in a new boiler installation quote?
Ask whether VAT is included in the written quotation. We show the rate and total clearly, so the amount due for the boiler installation is understood before approval of work.
How many new boiler installation quotes should I get?
Two or three comparable quotes usually give enough context without creating unnecessary delay. Ensure each follows a proper survey, so differences in boiler type, controls and installation scope are genuine.
