Frequently asked questions

You’ll find a list of commonly asked questions below, alternatively get in touch and we’d be happy to answer any questions you have.

Costs

One of the first things homeowners are concerned about is the initial heat pump system cost. Interestingly, heat pump systems are not as expensive to install as many people think. And, after the initial outlay, the energy savings that come with the system will, in the long run, outweigh the initial cost of central air source heat pump.

Plus who wouldn’t like to increase the value of their home? Air source heat pumps have been proven to add significant value to a property. Should you want to sell your home several years down the road, your heat pump system will be one of the major selling points.

Homeowners who opt for heat pumps stand to benefit from the Renewable Heat Incentive (RHI) scheme. But what is RHI and, more importantly, how can it benefit you as a homeowner?

The BUS is a scheme by the government whose aim is to encourage households and businesses to switch away from traditional fossil fuel systems to renewable heating technologies. The goal is to make sure that by 2020, 12 percent of heating is from renewable resources.

All property owners are eligible for RHI payments. These payments are tax-free for domestic customers and fixed for seven years for homeowners and 20 years for non-domestic customers. Regardless of whether the government withdraws RHI or makes changes to it, you still continue to enjoy payments for the duration of the contract.

Efficiency

Switching from your traditional heating system to an air source heat pump can result in massive energy savings.

Heat pumps have an average coefficient of performance (COP) of 350%. This means that they produce 3.5 kilowatts of heating or cooling power for every 1 kilowatt of electrical energy they consume. Given that conventional gas boilers have a COP of 70-80%, air source heat pumps are the undisputed winners in the heat pump vs. gas debate when it comes to energy efficiency.

How cool is it to have one system for both your heating and cooling needs? That’s an optional extra if you install a heat pump system.

The system can provide space heating or cooling at the touch of a button using a remote, a wall monitor, or a phone app. Due to the nature of its design, air source heating system works very quickly. Once the system has heated or cooled a space, it can sustain the desired temperature for as long as you want.

Servicing and maintenance

Once you’ve installed a heat pump system, how much work should you put in to make sure that the system stays in top shape for a long time? Fortunately, heat pump systems are a lot easier to maintain than combustion heating systems.

Firstly, heat pump systems usually come with a warranty of up to seven years. Their workmanship warranties can also last for years, and you can often opt for a warranty extension for a fee. Should the system develop a problem, the warranty takes care of it.

The typical air source heating system requires a professional service every year. Such regular maintenance is enough to make the system operate for 25 years or more.

Yes, we are able to service all Air Source and Ground Source Heat Pumps installed by ourselves only.

In order to ensure you get the maximum performance from your Heat Pump throughout its working life, you need to arrange for the system to be regularly serviced and maintained.

Home services FAQ's

Cavity wall insulation usually costs around £600 for a small two-bedroom apartment to £1,800 for a large four-bedroom detached house.

Cavity wall insulation is guaranteed for 25 years, but it can last for the life of the property.

Polystyrene bead cavity wall insulation allows water to run down into the ground instead of passing through to your walls, so it does not cause damp issues.

Cavity wall insulation is definitely worth having. It pays for itself within 3 to 5 years by saving you money on your heating bills. It can also add up to 3% to the value of your home.

For walls without a cavity you should consider internal or external wall insulation, which is an additional layer of wall added to the inside or outside of your property.

To find out if you already have cavity wall insulation, check your outside brickwork for evidence of small drill holes in the mortar. You can also check your home’s energy performance certificate online, or book a survey to have your walls inspected.

Cavity wall insulation is injected into the narrow cavity in your walls, which is there to prevent rainwater from seeping into your interior walls. Insulation is made from heat-trapping material to prevent heat loss from your home, while not allowing water to permeate through it.

Cavity wall insulation may become wet if the installation has failed. Check your walls for cold spots, discolouration, or signs of dampness or musty smells. You can also arrange a home survey to have your walls properly checked.

Removing cavity wall insulation is done using a process called extraction, which is essentially “sucking out” the insulation material through small holes in the wall.

Properly installed cavity wall insulation, using a modern material like polystyrene beads, should not need to be renewed. If any building works are carried out which could disrupt the walls or the insulation, you may want to get the integrity of the insulation checked.

Cavity wall insulation typically saves 11% to 16% off your energy bill each year. This is around £150 to £450 off the average bill, depending on the size of the property. The larger the property and the more exterior walls it has (detached house vs. mid terrace) the more it can save with cavity wall insulation.

Cavity wall insulation is covered by government schemes which can install it for free. If your council tax band is A to D and your home’s EPC rating is D or lower, you may be eligible for the Great British Insulation Scheme (GBIS). If you’re on income support or qualify as vulnerable, you may be eligible for the Energy Company Obligation (ECO4). Book a free no-obligation phone consultation with us to find out if you’re eligible.

Loft insulation is heat-trapping and weather-resistant material that is placed either between your roof beams, or in the rafters between your loft and your ceiling.

Loft insulation is covered by the UK government’s Great British Insulation Scheme. You may be eligible for free loft insulation under GBIS even if you’re not on benefits. If you live in Council Tax band A to D and have a home EPC rating of D or lower, you could qualify for this scheme. Book a free no-obligation phone consultation with us to find out if you’re eligible.

Loft insulation is covered by government schemes which can install it for free. If your council tax band is A to D and your home’s EPC rating is D or lower, you may be eligible for the Great British Insulation Scheme (GBIS). If you’re on income support or qualify as vulnerable, you may be eligible for the Energy Company Obligation (ECO4).

Loft insulation usually costs around £700 for a small two-bedroom apartment to £1,400 for a large four-bedroom detached house.

Loft insulation works by trapping heat which rises inside your home, preventing it from escaping through your roof. 25% of the heat lost from your home is lost through the roof, so preventing this heat loss is a big money-saver.

Loft insulation typically lasts at least 40 years, even up to 100 years, if properly maintained. It will pay for itself multiple times over its lifespan.

  • is loft insulation flammable?
    Loft insulation is made from non-flammable materials, or materials with an extremely high heat tolerance which will not burn even in a house fire.

  • is fibreglass loft insulation illegal?Fibreglass loft insulation is not illegal. This is a myth circulated by a telephone scam suggesting that new government regulations had banned fibreglass insulation. Fibreglass can cause irritation in people with breathing issues, but is otherwise a safe material to use. We do not use fibreglass, we use mineral wool insulation.

The most affordable and effective loft insulation is mineral wool such as Knauf Earthwool, which comes in rolls of rock, glass or mineral fibre. This type of insulation is the cheapest, is relatively easy to install and is a very good insulator.

Loft insulation can save you around 11% to 14% off your annual energy bill, which is roughly £200 to £350 depending on the size of your house. It prevents up to 25% of heat loss from your property, which means a significantly warmer and more comfortable home.

If your roof leaks and your loft insulation gets wet, this will affect its heat-trapping properties. Mineral wool materials like rock or glasswool are moisture-resistant, so they should work fine once you dry them out and won’t need to be replaced.

Loft insulation should not need renewing, as the material has an extremely long lifespan. The only exception is if your loft insulation does not meet the recommended 270mm thickness. You may want to consider upgrading if your insulation is too thin.

Loft insulation can save you around 11% to 14% off your annual energy bill, which is roughly £200 to £350 depending on the size of your house. Smaller homes with fewer exposed walls, like terraced houses, have the most to gain from loft insulation. Larger detached properties should focus on cavity wall insulation first for the biggest energy savings.

Solid walls can be insulated internally by fitting a secondary layer over the interior walls. This layer is filled with rigid insulation boards, or it may contain a cavity which can be filled like a typical cavity wall insulation would do.

Any wall which is exposed to the outside needs to be insulated to prevent the effects of bad weather from permeating through the wall into your home. Walls which are entirely indoors with no outside-facing parts don’t need to be insulated.

Internal wall insulation starts at around £3,300 for a two-bedroom apartment and can cost up to £11,000 for a four-bedroom detached house.

The lifespan of internal wall insulation varies with the material used, but you should expect it to last upwards of 25 years.

If internal wall insulation is properly installed, it should not need to be renewed or replaced for its entire lifespan.

Internal wall insulation typically saves you £200 to £660 off your annual energy bill, depending on the size of the house. Properties with more outside-facing walls, like large detached houses, stand to save the most from internal wall insulation.

Internal wall insulation is covered by government schemes which can install it for free. If your council tax band is A to D and your home’s EPC rating is D or lower, you may be eligible for the Great British Insulation Scheme (GBIS). If you’re on income support or qualify as vulnerable, you may be eligible for the Energy Company Obligation (ECO4). Book a free no-obligation phone consultation with us to find out if you’re eligible.

Room in roof insulation is used when you’ve converted your loft space into a room. It consists of insulation material placed behind the existing plasterboard of your loft room.

Room in roof insulation typically costs from £900 to £1,500, depending on the size of the property and the roof space.

You can expect to save between £250 and £450 off your annual energy bill, depending on the size of the property and the roof space.

If you’ve converted your loft space into a room but haven’t got it insulated, your home stands to lose up to 25% of its heat through the roof. Room in roof insulation is essential for loft conversions, to ensure a warmer home and energy savings.

Room in roof insulation is covered by government schemes which can install it for free. If your council tax band is A to D and your home’s EPC rating is D or lower, you may be eligible for the Great British Insulation Scheme (GBIS).

Ventilation is a way of controlling airflow through your home, to maintain a balance of fresh and clean air indoors without making your house cold or inflating your heating bills.

Ventilation usually comes in two forms. Natural ventilation is natural airflow from outside, delivered via trickle vents in your window and door frames. Mechanical ventilation is airflow being pushed or pulled from your home, such as an extractor fan.

If your home has cavity or solid wall insulation, you’ll need adequate ventilation to compensate for the reduced airflow. Ideally this ventilation will be distributed across the entire house.

There are many benefits to having a well-ventilated home. Many of us are living with substandard air quality without realising it. Having proper airflow eliminates damp problems and can have positive health effects too.

Trickle vents allow gentle airflow into your home without affecting the indoor temperature. These vents are designed to allow fresh air in without creating draughts. If your home is ventilated, you should keep your vents open at all times – even in winter.

If you plan on having insulation installed in your home, yes – ventilation is required, and it must be installed first. Since insulation limits the air transfer capabilities of the property, ventilation is needed to correct this. You’ll start feeling the benefits of fresh airflow to your home right away.

You might think so, but no! A proper ventilation system allows clean air to enter the home at a slow and steady rate, causing minimal change in temperature – so you can (and should) keep your vents open even in winter.

Our installers know where and how to install ventilation with minimum fuss – even if you’ve recently decorated or you don’t think you have a suitable location for it. Of course, any building work comes with a small amount of mess, but our installers will thoroughly clean up before they leave.

Yes! Your installer will make sure you understand how to use your new system before they leave.
