What we offer

Moving a boiler is usually part of a bigger plan: a kitchen refit that needs the wall back, a loft conversion, or simply wanting the boiler out of a bedroom cupboard. Most relocations happen alongside a boiler replacement, because the new appliance can be fitted straight into the new position. This page covers how we carry out the move and what decides the cost; for background on whether it is possible at all, see our advice article on moving a boiler.

John The Plumb is Gas Safe registered (554328) and a Worcester Bosch accredited installer. Every relocation starts with a free in-home survey of the old and new positions, and you receive a fixed price in writing. A magnetic filter is fitted as standard on boiler installations.

Boiler relocation: moving a boiler and what affects the cost

What limits where a boiler can go

Three things decide most relocations. The flue must exit to the outside in a position that meets clearance rules from windows, doors, boundaries and other openings, or run through the roof via a vertical flue. The condensate pipe needs a route to a drain that will not freeze. And the gas pipe must be large enough to supply the boiler at its new distance from the meter; long runs often need a bigger pipe. Water and heating pipework also have to reach the new spot.

Common moves

Kitchen to utility room or garage is a frequent request, as is moving from an airing cupboard to the loft, or from the middle of a kitchen wall into a corner unit. Each has its own considerations: a loft needs proper access, flooring, lighting and frost protection; a garage needs protection from cold; a cupboard needs enough clearance for servicing. We look at the practicalities of each option on the survey.

What affects the cost

The main factors are the distance between old and new positions, how many walls or floors the pipework crosses, whether the gas pipe needs upsizing, the type of flue required and how easily the condensate can be drained. Making good is another: lifting floorboards or chasing walls means some redecoration afterwards. Combining the move with a boiler replacement usually makes better use of the work than moving an old boiler on its own.

How the job runs

We agree the new position and the routes for gas, water, heating, flue and condensate before starting. On the day, the old boiler is removed and its connections capped or removed, the new pipework is run, and the boiler is mounted in its new location. The system is cleaned, a magnetic filter fitted, and the boiler commissioned and tested. Where pipework has been run through floors, we tell you what will need making good.

Planning around other building work

If you are refitting a kitchen or converting a loft, involve us early. Running new pipework before floors are laid and walls are finished is much tidier than doing it afterwards. Let us know your builder's schedule and we will plan the boiler move to fit.

FAQs

Frequently asked questions

Can you move a boiler to another room?+

Often, yes, as long as the flue, condensate drain and gas supply can reach the new position safely. The survey confirms what is possible.

What affects the cost of moving a boiler?+

Mainly the distance moved, pipework routes, any gas pipe upsizing, the flue type and the condensate route, plus any making good afterwards.

Is it better to move the boiler when replacing it?+

Usually. Fitting a new boiler straight into the new position avoids moving an old appliance that may need replacing soon anyway.
