Looking for a British Gas boiler quote and wondering what the alternatives are? Boilercentral.com is an independent online installer of mains-gas boilers. We are not British Gas and we are not affiliated with British Gas.
If you want a fixed installed price on screen before you speak to anyone, start our quote. Gas boilers supplied and fitted from £1,790. For most like-for-like swaps, next-day fitting is available if you order by 3pm, there’s a free slot at your postcode and the boiler is in stock. We fit 7 days a week.
How a British Gas boiler quote usually works
British Gas publishes two public routes to a new-boiler quote on its heating pages (checked 6 November 2026 on britishgas.co.uk/heating/new-boiler.html and its help pages):
- Online estimate — Answer questions about your home; British Gas recommends boilers. Their new-boiler page states that once you’re done, they’ll arrange a call with one of their experts to confirm your fixed price quote.
- Free home visit — Book a heating survey with their experts for a personalised fixed-price quote. Help pages also describe face-to-face Heating Adviser appointments.
British Gas also states that its quoted package includes system water treatment and cleanse, waste collection, a carbon monoxide detector and a room thermostat, and that new installs come with a 5-year British Gas warranty (parts and labour), with an annual boiler service needed to keep the warranty valid.
Takeaway: British Gas is built around guided estimating, a confirming call and/or a home visit, and a large national brand. That suits many homeowners — especially if you want someone to walk the property with you before you commit.
For British Gas price ranges and package detail on our site, use the advice guide: British Gas boiler prices. This page focuses on the quote journey, not repeating a prices encyclopedia.
How a Boilercentral.com quote works
- Answer a few questions about your home and current boiler.
- See fixed fitted prices for gas boilers that match your answers — Worcester Bosch, Viessmann, Alpha and Ideal.
- Choose your boiler and complete your online order — pick a date and finish the quote/order steps on screen.
- Upload photos of your boiler, flue and pipes after you order.
- Gas Safe fit — a local engineer removes the old boiler, fits the new one and commissions it. A straight combi-to-combi swap usually takes 4 to 6 hours. Conversions typically take longer (~2 days) and aren’t next-day.
You see the installed price for the quoted scope before you pay. No salesperson visit is required to get that online price.

Compare with my fixed Boilercentral.com quote
Price — how to compare fairly (no invented ranges)
We don’t invent British Gas list prices, and we don’t claim Boilercentral.com is always cheaper. British Gas confirms a fixed-price quote after an online estimate call or a home visit, so your figure depends on your home.
Use this written fixed-scope checklist when you have (or get) a British Gas quote and a Boilercentral.com quote:
- Same boiler type — combi / system / regular; like-for-like vs conversion.
- Same (or named) model and kW output — don’t compare a 24kW to a 35kW.
- Same location — boiler staying put vs relocated.
- Inclusions — old boiler removal, system cleanse/inhibitor, magnetic filter, thermostat/controls, flue parts, waste removal, CO detector.
- Warranty — length, who backs it (installer vs manufacturer), annual service rules.
- Earliest real install date — calendar date, not marketing slogans.
- Total payable for that scope — the full price, not a headline figure.
- Extras & change rules — what happens if extra work appears (scaffolding, building work, etc.).
Boilercentral.com installed prices start from £1,790 for the quoted scope. See also our new boiler cost guide and the British Gas boiler prices advice page for wider context — treat third-party “typical ranges” there as planning aids, not British Gas list prices.
Speed and next-day
For British Gas, check the installation date they give you in your quote and compare it with the date you can book elsewhere.
Boilercentral.com: for most like-for-like swaps, order by 3pm and — if a slot and stock allow at your postcode — we can fit the next day, 7 days a week. Conversions aren’t next-day. Details: next-day boiler installation.
Who should choose which?
Boilercentral.com may suit you if you:
- Want a fixed fitted price on screen without a salesperson visit to see it
- Prefer to get your fixed price online and book without a sales visit
- Want Worcester Bosch, Viessmann, Alpha or Ideal with a registered guarantee of up to 14 years depending on model
- Care about next-day availability for a like-for-like swap (subject to slot/stock)
- Are replacing a mains-gas boiler in England, Scotland or Wales
British Gas may suit you if you:
- Want a Heating Adviser visit or a guided call before you lock a fixed quote
- Prefer a large national energy-brand installer
- Are happy with their 5-year British Gas warranty package
- Already trust British Gas for energy supply or existing cover
Neither option is “wrong”. Get written quotes for the same scope and decide on price, warranty, date and service style.
