What “moving a boiler” actually involves
If you picture it like moving a microwave… yeah, it’s not that. Relocating your boiler means changing the things that keep it alive:
gas supply, heating flow/return, hot and cold feeds, condensate, flue position, electrics, controls.
Each one is manageable — the trick is doing them in the right order, safely, and leaving it looking like it belongs there.
Most of the time, boiler relocation in London falls into one of three buckets:
moving it within the same room (cupboard to adjacent wall), moving it across rooms (kitchen to utility),
or moving it to a different floor (rare, but it happens).
If you’re deciding whether you need a new boiler as well, start here:

Move boiler cost: realistic ranges in London
There isn’t one fixed “boiler relocation London” price because the route matters — flue, gas, condensate, and how much making good is needed.
But we can give realistic brackets that reflect what we see around North & East.
(And yes — if you’re also comparing new boiler prices or new boiler cost, those are different conversations: replacement vs relocation.)
Move boiler within the same room
Think: shifting from one side of a kitchen wall to the other, or moving within a cupboard run.
Often the least disruptive — but flue position still matters.
Typical add-on cost: from ~£600–£1,400 (job-dependent)
Best for: tidy access, short pipe runs, sensible flue routeMove boiler to a different room (kitchen ↔ utility)
This is the common one. You’re usually rerouting pipework and thinking harder about the condensate drain.
It’s not “hard”, it just needs planning.
Typical add-on cost: ~£1,000–£2,500
Watch-outs: boxing-in, floor lifts, external wall accessMove boiler to another floor
Not impossible, just more involved. You’re into longer runs, more making good, and you need a clean plan for the flue/condensate.
Typical add-on cost: ~£2,000–£4,000+
Usually: part of a refurbishment or layout changeIf you’re relocating AND replacing
This is where people get tangled: “boiler change prices” + relocation work. The quote should separate them clearly.
Otherwise you can’t compare properly.
If you’re also asking about boiler change prices, boiler fitted cost,
or cost of installing a new boiler, see:
new boiler cost guide.
Why do quotes vary so much? Because a “move” can hide a flue problem, a condensate routing problem, or a gas supply problem.
This page explains the bigger picture: why new boilers cost vary so much.
The three things that decide if a relocation is simple or a headache
If you only remember three words from this page, make it: flue, condensate, gas.
Most “moving boiler to kitchen” plans fall apart when one of those gets hand-waved.
1) Flue route + terminal position
You can’t just put the flue “where it looks neat”. It has to be safe, compliant, and practical.
London homes have extensions, narrow side returns, awkward alley access… we plan for reality.
If you want the rules explained plainly, here:
boiler flue rules and condensate drain in London.
2) Condensate drain
That little white pipe matters more than you’d think. Wrong fall, too long, or poorly routed and it becomes a winter problem.
We route it properly and protect it where needed.
Most “mystery call-backs” after installs are boring stuff like this.3) Gas supply sizing
Relocation can increase pipe run length. Longer runs = more chance of pressure drop if the sizing isn’t right.
We check the numbers rather than guessing.
Helpful read:

And yes — protection still matters after a relocation. If your system water is dirty, it’ll shorten the life of a shiny new boiler too.
We explain filters and inhibitor here:

How we handle a boiler relocation (without drama)
We don’t do the “we’ll figure it out on the day” approach. Relocations go smooth when the plan is clear:
confirm flue route, confirm condensate routing, check gas sizing, then tidy pipework and commissioning.

If you’re also changing the boiler at the same time, it helps to understand what’s included in the price:

Relocating boiler questions (the ones we hear constantly)
How much does it cost to move a boiler in London?
It depends on distance, flue route, condensate routing, and pipe runs — but simple moves in the same room are often the lowest add-on,
while cross-room or different-floor moves cost more. If you tell us where it is now and where it’s going, we can give a realistic range fast.
Can I move my boiler into a cupboard?
Often, yes — but it needs correct clearances, ventilation where required, safe flue routing, and practical access for servicing.
The cupboard has to be “engineer-friendly”, not just “looks tidy on Pinterest”.
Is moving a boiler to the loft a good idea?
Sometimes it’s brilliant, sometimes it’s a pain. Lofts can be cold, access can be awkward, and condensate routing needs care.
If you want it in the loft to free up space, we’ll check whether it’s genuinely sensible for your property.
Do I need a power flush if I’m relocating the boiler?
Not automatically — we assess condition. If the system water is dirty or radiators heat unevenly, cleaning and protection make a big difference.
Here’s the straight answer: do I need a power flush with a new boiler?
