Boiler packed up, or living on borrowed time? You can get a fixed price online in 20 seconds, pick your boiler and book a date. If you order before 3pm and there’s a free slot in your area, a Gas Safe engineer can fit it tomorrow. We fit 7 days a week, weekends included.
There’s no home survey and no salesperson. After you order, we’ll ask you to upload a few photos of your boiler and pipework so your engineer turns up ready. You see the full price before you pay, and the price you see is the price you pay.
Gas boilers fitted from £1,790. Next day if you order by 3pm. Guarantee of up to 14 years depending on model.
Order before 3pm. Your fixed price and first free date in 20 seconds, no survey needed.
How it works
- Get your price. Answer a few quick questions about your home and your current boiler. It takes about 20 seconds and you’ll see fixed prices on screen.
- Pick your boiler. We’ll show you the boilers that suit your home, from budget models to top-end ones, each with its installed price.
- Book a date and send your photos. The calendar shows the first date we can fit at your postcode. If tomorrow’s free, it’ll say so. Once you’ve ordered, upload a few photos of your current boiler, flue and pipes.
- We fit it. A Gas Safe registered engineer removes the old boiler, fits the new one, tests it and shows you how the controls work. A straight combi swap usually takes 4 to 6 hours.
When next day isn’t possible
Next day fitting depends on a few things, and we’d rather tell you now than let you down on the day:
- Order time. Order before 3pm for installation the next day. Orders after 3pm go to the day after.
- Weekends. We fit 7 days a week, so a Friday or Saturday order can still be fitted the next day.
- Your photos. We need your photos uploaded before we can confirm the job, so send them as soon as you’ve ordered.
- Your area. Slots depend on engineers near your postcode. The booking calendar shows your real first date before you pay.
- Stock. If a boiler’s short with the supplier, its page will say “subject to availability” and you’ll see a later date.
- The job. Next day is for like-for-like swaps, such as combi to combi. Conversions, like swapping a system or regular boiler for a combi or removing a back boiler, take 2 days, so they aren’t next day. You’ll still see your first available date when you book.
If tomorrow’s gone, the calendar shows the next free date, which is often the same week.

Next day boiler installation FAQs
Can I really get a new boiler fitted tomorrow?
Yes, if you order before 3pm, there’s a free slot at your postcode and your boiler’s in stock. The booking calendar shows your first date before you pay.
Do I need a home survey first?
No. Your answers online give us what we need to price the job. After you order, we’ll ask you to upload a few photos of your boiler and pipework instead.
How long does the installation take?
A combi-to-combi swap usually takes 4 to 6 hours. Conversions, like system or regular to combi or removing a back boiler, take 2 days, so they aren’t next day. For the full process and what’s included, see new boiler installation.
Do you fit on weekends?
Yes. We fit 7 days a week, Saturdays and Sundays included.
What if tomorrow isn’t available?
The calendar shows the next free date at your postcode, and you can book that or any later date.
Can I spread the cost of a next day installation?
Yes. Finance is through Zopa with no deposit: 0% over up to 3 years, or interest-bearing plans over 4 to 10 years. Options are shown at checkout, subject to status.
