Irrespective of heating system type, the overall average new boiler cost in London comes in at £2,261 which unsurprisingly comes in over the current national average by approximately 8% - which to be fair, is probably cheap... for London.

Boiler installation in London - Final Take... 

So what's to take from all this boiler madness?

For arguably the most expensive city in the world, you're not actually getting a bad ride on boilers - particularly on combi swaps and particularly in North London.

London boiler prices are considered to be the 'funniest' prices in the UK enconomy.

Our take-home tip would be to - obviously - shop around and get several quotes but also to consider that many installers will be willing to travel across London so if you find a great deal on the other side of the city, don't be shy about asking if they'll cover your area. Many of them will do!

Good luck with the whole London situation, hang on in there.
