New Boiler Installation in Camden
The right replacement boiler depends on your home, not the installer's stock: bedrooms and bathrooms, hot-water demand, mains flow rate, and what the existing system is. Our quote form asks exactly those questions so Camden installers can price accurately first time.
What a new boiler costs
National bands, installed: a like-for-like combi swap typically £1,800–£2,800; converting a cylinder system to a combi £2,500–£4,000; a system boiler with unvented cylinder £2,800–£4,500 depending on cylinder size. Within each band, the boiler's brand tier, the warranty length, flue complexity and any pipework upgrades move the number. Every Camden quote itemises those elements so you can see exactly what you're paying for — and what you could trim.
Combi, system or heat-only — the honest steer
Combi boilers heat water on demand — no cylinder, no tank, ideal for homes with one bathroom and decent mains flow. System boilers feed an unvented cylinder: better for two-plus bathrooms running simultaneously, at the cost of cylinder space. Heat-only (conventional) boilers with tanks suit some older systems where wholesale conversion isn't worth it. The deciding facts are your bathroom count, mains flow rate and airing-cupboard real estate — not fashion.
What happens on installation day
Day one, the outgoing boiler comes off and the new one goes up: flue, condensate, gas and water connections made, the system flushed and dosed, filter and controls fitted. Commissioning is the part that separates professionals — combustion analysed, gas rate verified, the benchmark log completed and building control notified. You end the day with a working system, a registered warranty and paperwork that will matter when you sell the house.
Water quality quietly decides how long heating components last around Camden. Camden's water is hard London standard — scale steadily furs elements and cartridges, and period conversions feel it first in weakening showers and slow-filling cisterns. Where scale is a factor, protection on the boiler's cold supply and properly inhibited system water do more for the appliance's lifespan than any brand choice on the quote — and our engineers will say so.
Frequently asked questions
How much is a new boiler in Camden?
Most Camden combi replacements land between £1,800 and £2,800 installed; conversions and system-boiler installs range higher, typically £2,500–£4,500. Your fixed quote follows a survey — the quote form on this page captures what the surveyor needs to price accurately.
Which boiler brand should I choose?
The honest answer: any of the major brands at the right size, installed well, will serve you. Differences lie in warranty length, parts availability and price tier. Our brand hub compares them factually — and a good installation matters more than the badge.
Is the quote really fixed?
Yes — after survey, the price is fixed and itemised. The only changes are ones you approve in advance (for example, if opening up reveals pipework that must be brought to standard). Doorstep additions are a breach of network standards, not a negotiating tactic.
Will you take away my old boiler?
Yes — removal and responsible disposal of the old appliance and any redundant tanks or cylinders is included in network quotes. Cylinder and tank removal in conversions is itemised so you can see its share of the price.
