Step by step

What kind of property is it?

How many bedrooms?

How many bathrooms?

What boiler setup do you have now?

Does the boiler need moving?

Include a system clean / upgrade allowance?

Your estimate is ready.

The range appears alongside the calculator. Send your details after this step and we can use the result as the starting point for the installation conversation.

What changes a boiler quote?

The appliance is only one part of the installation.

Two homes with the same number of bedrooms can need very different boiler work. These are some of the factors a proper survey needs to confirm.

System type

Combi, system or regular

A like-for-like replacement is different from changing the way the home stores and delivers hot water. Cylinders, tanks and pipework can all change the scope.

Location

Flue, gas & condensate routes

Keeping the boiler in place is usually simpler. Moving it may involve new pipe routes, drainage for condensate, flue design and making good.

System health

Water quality & circulation

An installation should consider sludge, filters, radiator performance and existing controls so the new boiler is connected to a system that is ready for it.

From estimate to final quote

Why we still survey the property.

The calculator is designed to answer the first budgeting question quickly. The survey answers the technical questions that cannot be seen online: gas-pipe sizing, flue position, condensate route, water flow, controls, access and the actual condition of the heating system.

It also gives us a chance to understand what you want to improve. A replacement may be about reliability, better hot water, a different boiler location, smarter controls or part of a wider renovation. The final recommendation should reflect that goal rather than simply replacing like for like by default.

  • Confirm property and household hot-water demand
  • Assess existing boiler and heating-system arrangement
  • Check practical installation routes and access
  • Discuss controls, protection and any related upgrades
  • Provide a clear final scope and quotation
Already know you need a replacement?

Send photos with your enquiry.

Photos of the current boiler, nearby pipework, controls and any hot-water cylinder can make the first conversation more useful. Include the property postcode and tell us whether you are considering moving the appliance or changing the hot-water setup.

Boiler quote FAQs

Useful questions before the survey.

Is the online boiler estimate a fixed quote?

No. It is an indicative budgeting range based on the answers selected. A survey is needed before the final boiler specification and quotation are confirmed.

Why does moving a boiler affect the price?

A relocation can require new flue, condensate, gas and heating pipework routes, along with access and making-good work. The amount varies significantly by property.

What if I do not know what type of boiler I have?

Choose the not-sure option and send a photo of the boiler and any hot-water cylinder or tanks when you enquire. We can identify the existing arrangement before the survey.

Does the estimate include radiators or major system upgrades?

The estimator focuses on boiler installation and a basic allowance for system cleaning or upgrading. New radiators, cylinders, major pipework changes and other wider work would be assessed separately.

Which areas can I request a boiler quote for?

Infinite is based in Lindfield, Haywards Heath and covers Lindfield, Cuckfield, Newick, Henfield, Heathfield, Burgess Hill and surrounding areas, with selected work in Brighton and Hove.
