Underfloor Heating Installation Costs

Material Costs, Labour Fees and Time Frame Estimates for Installing Underfloor Heating

Costs for underfloor heating installation can vary based on the specific area you want to heat as well as the overall complexity and intricacy of your chosen system. Regardless of the type of underfloor heating system you pick out, your existing floors will require removal for the heating system to be fitted in. However, electric heating systems for your underfloor are considered to be generally easier to install and are considered ideal due to how the system doesn’t require extensive pipework to be added. 

The typical costs required for underfloor heating installation systems could amount to £70 a square metre if you’re installing a loose-wire type or £60 a square metre for electric mats. If you’re interested in a water-based system, expect the costs to be about £100 a square metre. Meanwhile, whole-house installations will cost around £2500. 

Costs for the underfloor heating installation project will be based on the specific area you want to be heated and what its dimensions are, the system type, and the amount of groundwork needed. The ideal electric systems utilize electric wire networks that run under the floor surface. Whilst it does help warm the floor, it might not be that effective if your goal is to get the whole room heated up efficiently. These types of systems are more suited when added to smaller rooms. For this type of system, heating mats are probably the simplest to install. You also have the option to go for wet underfloor systems as they are quite versatile and can work with a variety of flooring types. However, since the whole installation process is more on the tedious side, they’re best done on bigger and wider areas or even better, for heating an entire house. 

Most professionals in underfloor heating will charge a daily rate of £200 to £300. The total length of time it would take for the project to get done will be dependent on whether an electric or wet system is being installed. Wet systems will be more time-consuming since pipework is necessary— which could take an additional four days. The electric option is much quicker as getting the entire home fitted would only take a maximum of two days. 

Price generally varies based on the specific type of property you reside in. For instance, it is easier to carry out the installation when you have a new build property, which could lead to lower labour costs. For home renovations, costs per square metre could amount to £65. 

Cost Breakdown

Individual costs for installing an electric underfloor heating carried out during a home renovation could be around £1500. Of that, £1125 covers the materials and £375 pays for the tradesmen fees. 

Time Frames and Labour Costs

Professional costs for getting underfloor heating installed is about £300 a day. On average, it would take around two days for the installation to complete. Bigger projects could take about 4 days. Some could even take a week especially if you intend to have the installation done over a heated system. Some installation experts charge a rate of £100 a square metre. However, if you want a water-based system, costs could run up to £30 an hour for the services of a plumber. If you want an electric system, an electrician is necessary so expect to get charged around £30 an hour.

What does the Job Entail?

If you wish to hire the experts for the installation of your underfloor heating system, understanding what the process is helps you determine whether the job was done efficiently and correctly. 

Electric Systems

  1. Your floor space is measured to determine the amount of flooring needed
  2. The insulation is laid out.
  3. Your power source is identified along with the drilling hole to accommodate the cables.
  4. A conduit is cut into your insulation so flexible pipes can be fitted.
  5. The area is cleaned of debris and dust.
  6. The mats will be tested for resistance via a multimetre to ensure that they are fully functional.
  7. The matting is laid down and secured after ensuring that it’s in position.
  8. The probe is positioned in the appropriate place to ensure that the temperature is accurately recorded by the thermostat.
  9. Resistance-testing using the multimetre. 

Water-based Systems

  1. Floor heating pipes are connected to the manifold.
  2. The piping and insulation are laid out.
  3. The piping is secured to your insulation using pipe staples while making sure that there’s ample space for proper heat distribution.
  4. Piping is looped across the floor, ensuring the large rooms utilize multiple loops.
  5. Pipes are pressure-tested and filled up with water.
  6. The screed is prepared and then poured over the pipework.
  7. A chemical spray is used to spray over the screed and then tamp it down using a brush. 

Factors Affecting Costs

A variety of cost factors must be considered when deciding on underfloor heating. For instance, you need to decide between a suspended or screed floor. Screed floors are more budget-friendly which involves quick installation. Suspended floors will involve the installation of thick insulation positioned right beneath the floor. This is more complicated and will cost more. Screeding will usually cost around £210 and could take about 7 hours to get done, relative to the room size. Suspending floors could amount to £900 for most homes. 

The size of your floor will also need to be taken into consideration. Whilst you might think that it will cost more to install underfloor heating in larger rooms, what’s more costly is having it installed in multiple rooms as different rooms will require their own thermostats. Generally, costs for these kinds of projects could range from £25-£100, depending on the specific type of technology you prefer using. 

Labour is another factor you need to look into when determining underfloor heating costs. Contractors will usually charge depending on where you are located and how experienced they are. If the budget is a bit of a challenge, you always have the choice to go for a less experienced contractor. This will come with certain risks though as they may not be as efficient at what they do considering how they have not had that much exposure to the project. 

Is DIY Possible?

It may be possible to go DIY if you are installing an electric system as it is more straightforward. You effectively keep costs at £500 and below if you’re going for an electric kit and about £1000 if you want to go for a wet kit. If you have no experience whatsoever, you’ll need to hire the services of a professional electrician or plumber at around £30 an hour rate. 

You can further reduce the costs by completing other jobs including fitting the pipes or pads as well as laying the insulation. However, you also need the services of a professional that will ensure that IEE regulations are met for safe underfloor heating installation. Getting a professional to sign off the installation will at least help you avoid unnecessary problems later on. 

Costs for Running Underfloor Heating

Underfloor heating can be fairly expensive to install upfront and a lot of people seem to be put off with the prospect. However, instead of just focusing on the costs for the installation, you should instead look into the various long-term upsides of this project. Getting the underfloor heating installed can help reduce your monthly energy bills in the long run. Water systems are considered as the best in terms of energy-efficiency as it is about 25% more effective compared to typical radiators. Running this system isn’t as expensive as well as it would only cost a yearly amount to £22 a square metre to run. Electric systems can cost around 10p a square metre to run for a 6-hour time. Costs will vary depending on how large or small the room is. 

Underfloor Heating Benefits

There are a variety of advantages you can get out of installing underfloor heating.

  • Great for saving space as it reduces the need for radiators so it will not take up wall or floor space.
  • Energy-efficient and can help you get massive savings. Wet systems are even more cost-efficient.
  • Offer increased underfoot whilst keeping your home warm.
  • You can improve your property value via these heating projects.
  • You get the benefit of better-distributed warmth. 

Can I Save Money with Underfloor Heating?

Despite the costly up-front figures which might put some people off, this is a great solution that will significantly reduce your energy consumption in the long run. With the underfloor heating present, you will require less heat inside your home, especially if you have a water-based system installed since it can be operated at low temperature. You can even monitor your overall usage by getting a thermostat that will track your overall heating habits so you don’t just get to reduce the costs for your energy consumption as well make your residence more eco-friendly. 

Will this Add to My Property Value?

Having an underfloor heating system installed can lead to a benefit of 5% increase in its overall property value. Home buyers are, after all, interested in properties that will let them save energy, as well as properties that are more comfortable and eco-friendly. This can be attractive to people looking for greener options and those who are looking for ways that they can reduce carbon footprints. 

Underfloor Heating Removal Costs

If you need to get your underfloor heating removed, expect that this will be a complicated job and several steps are involved to carry it out. The top flooring needs to be removed first which can cost around £32 a square metre but this would be highly dependent on the floor type you have. After the top has been lifted, the next step is to remove the heating system. If you have a water-base done, you need a plumber to help you out which could cost you about £30 an hour. If you have an electric system, you need an electrician. They generally charge a rate of £30 to £40 an hour. The job can be time-consuming so depending on the size of the room, it could take up to a week to get the task completed.
