Why Getting a Boiler Installation Quote Early Saves You Money
Getting a boiler installation quote early gives you room to compare properly and ask better questions. Our guide to boiler installation cost in Swindon explains what affects your quote, combi boiler prices and installation time.
The numbers make the case. According to Heatable's analysis of new boiler installation costs, the median quoted price for a standard combi boiler replacement was £2,300, based on 2,000 quotes generated between January and June 2026. That's a median, not a promise. Quotes around it vary widely, and the gap between a fair price and an inflated one usually comes down to how much detail the installer has gathered before pricing the job.

What Happens During a Boiler Installation Survey
- Measure rooms and count radiators to estimate heat loss
- Check gas supply, pipework and flue routes
- Test water pressure and flow rate at the taps
- Confirm boiler size based on hot water demand, not just floor area
- Note any extra work, such as moving a flue or upgrading controls

How to Compare Boiler Installation Quotes Fairly
When comparing boiler installation quotes, consider the scope of work as well as the totals.
What a Proper Quote Should Itemise
| Item | What to Check | Why It Matters |
|---|---|---|
| Boiler make and model | Exact model and output rating | Confirms you're comparing like for like |
| Labour and extras | Flue, filter, controls, pipework | Hidden extras inflate the final bill |
| System flush | Included or not | Affects efficiency and warranty |
| Certification | Gas Safe registration number | Legally required to work on gas |
| Warranty terms | Length and what's covered | Protects you after installation |
| Timescale | Start and completion dates | Avoids open-ended scheduling |

How Long Boiler Installation Time Actually Takes
Most same-position replacements finish within a day. Moving the boiler, converting from a back boiler, or adding a cylinder pushes it longer. Plan for the heating to be off during the work, and ask the engineer what happens if the job overruns.

Frequently Asked Questions
How do I get a quote for a new boiler installation?
Start with our online quote tool if you want an indicative price before committing. B&G Jenkins offers an instant quote tool that takes under two minutes.
What should a boiler installation quote include?
A thorough quote should itemise the boiler make and model, any new controls or thermostat, labour, flue and pipework changes, and whether old boiler removal is included. Ask whether the price covers building regulations notification and any making good afterwards. Vague single-figure quotes make it hard to compare boiler installation quotes fairly, so request a written breakdown before you accept anything.
How long does it take to install a new boiler?
A straightforward like-for-like combi swap is usually done in a day. Converting from a conventional system, relocating the boiler or upgrading pipework can stretch boiler installation time to two or three days. Your installer should confirm the expected timescale in writing once the survey is complete, so you can plan around any time without heating or hot water.
