What changes the cost of moving a radiator?
Moving a radiator is priced on how far the pipes have to go, whether they run under a floor, along a skirting or inside a wall, and how much draining, refilling and making good the job needs. This guide prints no price, and GOV.UK says extensions to central heating systems may need building control in some cases [S1].
Last reviewed:Why move a radiator?
People move radiators to free a wall for a sofa or kitchen units, to make space for a new window or door, or as part of a bigger refit. Sometimes a radiator under a window simply suits the room better than one on a long wall, or the other way round.
This guide does not print a price. It explains what changes the quote and what to ask before you agree to one. QuoteZila starts in Cheshire, with Crewe, Nantwich and Sandbach first, and anyone in the UK can post the job.
What does moving a radiator involve?
A plumber moving a radiator will usually:
- Turn the heating off and let it cool.
- Drain the system or the part that feeds the radiator.
- Take the radiator off its brackets and cap or remove the old pipe tails.
- Run new flow and return pipes to the new position, under the floor, along the skirting or inside the wall.
- Fit new brackets and, often, new valves.
- Refill the system, add inhibitor if agreed, let out trapped air and test for leaks.
- Balance the radiators so each one heats properly.
This page does not give DIY steps. Draining and refilling a sealed system, and working near the boiler, are jobs for a plumber or heating engineer. If the boiler itself needs any gas work, HSE says anyone employed to work on gas appliances in a home must be a Gas Safe registered engineer [S3].
What changes the price of moving a radiator?
| Factor | What to ask | Why it moves the price |
|---|---|---|
| Distance | How far is the new position from the old pipes? | Longer runs mean more pipe, fittings and time |
| Floor type | Suspended timber or solid concrete? | Lifting boards is quicker than chasing a solid floor |
| Pipe route | Under the floor, surface-run or buried in the wall? | Hidden routes take longer and need making good |
| Same radiator or new | Is the old radiator being reused? | A new radiator adds its own price |
| Valves | New thermostatic valves and lockshield, or reuse? | New valves add parts and labour |
| Draining and inhibitor | Full drain-down, and is inhibitor included? | Adds time and materials |
| Wall and brackets | Plasterboard, brick or a stud wall? | Fixings and reinforcement vary |
| Making good | Who refits floorboards, fills chases and decorates? | Often left out of a first quote |
| Number of radiators | One radiator or several in one visit? | Several moves on one drain-down can share labour |
| VAT | Included or extra? | Changes the total [S4] |
Does moving a radiator need building control?
GOV.UK's guide to building work lists "extensions to central heating systems" among examples of notifiable work, marked as work that may not need to be notified in certain circumstances [S1]. The same guide lists the addition of a radiator to an existing heating system as work you need to tell a building control body about, again noting that it may not need notifying in some circumstances [S1]. GOV.UK's approval page lists adding extra radiators to a heating system among jobs that need approval [S2].
Moving an existing radiator sits close to those examples. Ask the plumber whether they think it needs notifying, and whether they are registered with a competent person scheme. If you are unsure, GOV.UK says to check with a building control body [S2]. GOV.UK explains building regulations approval. GOV.UK: building regulations approval.

Does the radiator suit the new position?
A radiator that heated the room well in one place may not do as well in another. Before you commit, ask the plumber a few questions about the new spot:
- Is the radiator big enough for the room? If the room is being extended or opened up, the old radiator may be too small. A plumber can work out the heat the room needs.
- Will furniture block it? A sofa or a deep shelf in front of a radiator traps heat behind it. Leave space in front and above.
- Is the wall strong enough? A large double radiator full of water is heavy. A stud wall may need extra timber behind the brackets.
- Are there cables or pipes in the wall? Chasing a wall for new pipes means checking for hidden services first. Ask the plumber how they will check.
- Is it near a door or a curtain? Long curtains hanging over a radiator send heat up behind them.
If the answer to the first question is no, it may be worth pricing a new radiator for the new position at the same time.
When is the job bigger than it looks?
Some moves turn out to be more work than a short pipe extension. Expect a longer quote, or a visit before quoting, if:
- the floor is solid concrete and the pipes need to be chased into it
- the pipes are microbore, the thin type sometimes found in older systems, and the plumber needs to change the layout
- the system is old and draining it may stir up sludge, which might lead the plumber to suggest cleaning the system too
- the new position is on an outside wall that needs new fixings through render or cladding
- the move is upstairs and the pipes have to drop through a ceiling below
None of these means the job cannot be done. They are reasons to ask for a site visit and a written quote, rather than a price over the phone.
A plumber who has seen the floor, the pipes and the wall can give a fixed quote. A plumber who has only seen a photo can usually give an estimate at most, and an estimate can change once the boards are up. If you can, be at home for the visit so you can point out where furniture will go and answer questions about the floor.
Plan the move with other work
The disruption of moving a radiator is mostly in the floor and walls, so timing matters:
- Before new flooring. With carpets and boards up, pipes can run underneath and the tails come up exactly where you want them.
- Before plastering or decorating. Chasing pipes into a wall and filling the chase is easier before the wall is skimmed or painted. See our plasterer cost guide for that side.
- During a kitchen refit. The plumber can move the radiator and run pipes for a sink or dishwasher in one visit.
- With other heating work. If you are also changing valves or radiators, one drain-down can cover all of it.
If you only need a valve changing, our page on how to replace a radiator valve explains that smaller job. For a straight swap of the radiator itself, see radiator replacement costs.
How do you compare quotes to move a radiator?
Ask each plumber for the same details so you can compare like with like:
- the new position and the pipe route, in writing or on a sketch
- whether the radiator is reused or replaced, and its size
- which valves will be fitted
- how the system will be drained and refilled, and whether inhibitor is included
- who lifts and refits floorboards, fills chases and decorates
- whether building control needs telling, and who does it
- the total, with VAT shown
Citizens Advice says to try to get written quotes from at least 3 different traders, and that a quote is a fixed price while an estimate is just a rough guess [S5]. It says some traders charge for quotes, so ask about this first [S5]. Our plumber cost guide explains how call-out and hourly prices are usually set out.

Questions about moving a radiator
How much does it cost to move a radiator?
This guide does not print a figure. Moving a radiator a short way along the same wall is a different job from moving it across a room with pipes under a solid floor. Ask each plumber for a written quote that lists the pipework, the draining and refilling, any new valves and the making good.
Does moving a radiator need building regulations approval?
GOV.UK lists extensions to central heating systems among examples of notifiable work that may not need to be notified in certain circumstances. It lists adding extra radiators to a heating system among jobs that need approval. Moving an existing radiator is close to both, so ask the plumber how they will handle it, and check with building control if in doubt.
Will the whole heating system need draining?
Often at least part of it. The pipes to the radiator have to be cut and extended, so the water in that part of the system has to come out or be held back. Ask how the plumber will do it, whether inhibitor will be added when it is refilled, and whether the radiators will be balanced afterwards.
Should I move the old radiator or buy a new one?
It depends on the radiator. If the old one is sound and the right size, moving it saves buying a new one. If it is old, rusty or too small for the room, a new radiator in the new spot can make sense. Ask the plumber to price both options.
Can I move a radiator before the floor is laid?
That is often the easiest time. With the floor up, pipes can run underneath with less disruption. Tell the plumber what floor is going down and when, so the pipe tails come up in the right place.
Does VAT change the price?
It can. A business must register for VAT if its taxable turnover for the last 12 months goes over £90,000. Ask each plumber whether their quote includes VAT.
Does QuoteZila check plumbers?
No. We don't check insurance, qualifications or registrations, so please check these yourself before you hire. You can report a quote or a business from your job page.
This page is general information, not professional or legal advice. QuoteZila does not check Gas Safe, WaterSafe, NFRC, NICEIC or other registrations against the register on your behalf: look them up yourself.
