You can order a new mains-gas boiler online with installation included — fixed installed price from £1,790, pay online, then a local Gas Safe engineer fits it. For what happens on the day, see new boiler installation.
Start the quote, see prices for boilers that suit your answers, pick a date and pay. After you order, upload photos of your current boiler and pipework so the engineer turns up prepared. 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 to buy a boiler online
- Answer a few questions about your home, your current boiler and where it sits.
- Compare fitted prices for the gas boilers that match your answers — each shows its full installed price.
- Pick a date and complete your online order. Finish the quote/order steps on screen for your chosen boiler.
- Upload your photos of the current boiler, flue and pipes so the engineer arrives ready.
- We fit it. A local Gas Safe engineer removes the old boiler, fits the new one, tests it and shows you the controls. A straight combi-to-combi swap usually takes 4 to 6 hours.
The price you accept is the price you pay for that job scope. Extras (major relocation, large flue/pipework changes, conversions) appear on the quote before you pay.
A boiler with installation — not just a box
We don’t sell boilers on their own. Every Boiler Central price is supplied and fitted. Your quote confirms the full list; as standard that covers:
- Removing your old boiler
- Gas, water and electrical connections the new boiler needs
- Cleaning your central heating system
- Fitting and connecting the new boiler
- Commissioning and testing
- A wireless thermostat, set up and ready
- Gas Safe notification and manufacturer guarantee registration (your quote shows the guarantee for each boiler)
How soon can it be fitted?
For most like-for-like gas boiler swaps, order by 3pm and — if there’s a free slot near you and the boiler is in stock — we can fit the next day. We fit 7 days a week, weekends included. If tomorrow isn’t free, the calendar shows the next available date before you pay.
Conversions (system or regular → combi, or removing a back boiler) usually take around 2 days, so they aren’t next-day.
Full rules: next-day boiler installation.
