Boiler guide · 4 min read · Updated October 2026
The honest options for spreading the cost of a new boiler, what cheap installation offers really mean, and how our deposit works.
A headline figure hundreds of pounds below everyone else is almost always one of three things: the boiler only (no labour), a stripped installation with no flush, filter or commissioning, or a lead-in price that grows at survey. Ask what the figure includes before comparing it.
Fitted installations: a 20% deposit reserves your installation date and the balance is due on completion — you do not pay in full for work that has not happened. Supply-only shop orders are paid at checkout and delivered within the stated lead time.
Government-backed schemes for boiler replacement exist but are narrowly targeted — mostly at low-income households moving off the least efficient heating. We do not administer grant schemes and will not imply your quote is subsidised when it is not.
Our standard terms are a 20% deposit with the balance on completion for fitted work. We do not currently offer in-house finance plans.
Check what is included: flush, filter, commissioning, Benchmark and warranty registration. A quote missing those is not the same job.
