Frequently Asked Questions2020-08-21T12:06:52+00:00
What is Solar PV?2023-01-25T16:24:32+00:00

PV stands for Photovoltaics and means converting light into electricity.

Solar PV systems use cells, stored in a panel, to convert sun and daylight into electricity for you to use for free in your home.

How Does it Work?2023-01-25T16:24:08+00:00

A PV panel is a unit consisting of special cells that generate an electric current from sun and daylight. When the sun shines over the cells, an electric field is created.

What are the benefits of having Solar PV Panels?2023-01-25T16:23:48+00:00
  • Become more sustainable at home.
  • Use less carbon.
  • Lower your electricity bills.
Do Solar PV panels need direct sunlight to work?2023-01-25T16:23:28+00:00

No. The stronger the sun/daylight, the more electric energy is produced. Nevertheless, the cells do not need direct sunlight to work, and they can still produce electricity on a cloudy day.

How do I use the electricity that I have generated?2023-01-25T16:23:08+00:00

If you have a demand for electricity in your home e.g. you need to turn on an appliance such as a kettle or washing machine, the invertor makes sure that the electricity you have generated is used first. If there is not enough, then more is drawn from the grid to top it up. This is automatic and seamless, so you do not need to do anything to make it happen.

Will Solar PV Panels save me money?2023-01-25T16:22:47+00:00

Yes. You will save money on your fuel bill as you will be using electricity that you have generated for free rather than pay a company to do it for you. Having solar PV could save you up to 70% on your fuel bills.

How long do Solar PV Panels last?2023-01-25T16:22:23+00:00

This varies depending on different manufacturers but most come with a 25 year manufacturer’s warranty and have an expected life span of well in excess of 25 years.

How long will the installation take?2023-01-25T16:22:02+00:00

On average, this will take 1 day but it will depend on how many panels are being installed.

Are your Installers qualified?2023-01-25T16:21:42+00:00

Yes. All our installers are qualified to install renewable technologies such as Solar PV Panels and as a company we are also accredited with the Microgeneration Certificate Scheme. This is an independent certification scheme.

Are you insured?2023-01-25T16:21:21+00:00

Yes. We have Public Liability Insurance, Employers Liability Insurance as well as other industry specific insurances.

Will my roof be strong enough?2023-01-25T16:21:00+00:00

Most roofs are strong enough to support a Solar PV Panel installation without any reinforcement. However, we will perform a full survey of your home and make an assessment of this prior to installation.

Do panels need cleaning?2023-01-25T16:20:40+00:00

Usually, dust and dirt washes off when it rains. However, we suggest an annual clean using a pressure hose to ensure any dirt is washed away to prevent power reduction.

How much money can I expect to save on my energy bills after the install?2023-01-25T16:20:12+00:00

Generating your own electricity using Solar PV Panels means you will no longer be reliant on buying electricity from a supplier. This will reduce the amount of money you spend on powering your home.

These figures are taken from the Energy Savings Trust website and are based on the April 2022 energy price cap.

What happens if there is a power cut?2023-01-25T16:19:23+00:00

Solar PV systems that are grid connected will automatically shut down if there is a power cut. The invertor needs grid power to start up and operate so if there is a power cut it won’t work. This is a safety measure designed to stop electricity leaking on to the national grid and to protect individuals who may be working to restore the power supply.

How do you extract cavity wall insulation?2020-01-08T16:00:23+00:00
  1. Inspect the site both on the inside and the outside of the property. This inspection will most notably be looking for any cracks that have become apparent where dust, debris and insulation particles can enter the home. If we do find any such cracks we then seal these before proceeding further with the job.
  2. We will remove bricks to allow us access to the cavity (in the cases of rendered properties we would instead drill ‘core’ holes’.
  3. We use an industrial grade vacuum (designed especially for cavity wall insulation extractions) and insert the nozzle into the cavity; this is coupled with a machine that blows air into the cavity, and together the two work in tandem to clear out the old insulation. Often we couple this with other removal tools, such as an item known as the whip.
  4. Once the cleaning process is complete with all debris removed we then take a closer look at the cavity using a camera on a rod, known as a Borescope – this simply confirms that we’ve cleared every last mortar piece and brick end out.
  5. We then replace and re-point the bricks and drill holes – being sure to use the right colour for a seamless finish.
  6. Finally, we undertake an inspection of the work and ensure that we leave the property spick and span with both an inside and outside tidy up.
Why does rubble, bricks or debris cause issues with cavity wall insulation?2020-01-08T15:59:22+00:00

One of the most common causes of issues with cavity wall insulation that could otherwise have been avoided is linked to debris such as brick ends, mortar or rubble being left behind within the cavity.

This happens as these items (known within the industry as ‘snots’) lie at the foot of a wall within the cavity ties. Usually, as rainfall hits the exterior of a property, the ties will guide the water away ready for evaporation, however when these ties are blocked by snots the moisture cannot escape – and instead seeps into the inner wall and eventually turns into a damp spot.

One of the most effective ways of establishing whether a cavity wall has been compromised in such a way is through Thermal imaging.

Are any other property types unsuitable for cavity wall insulation?2020-01-08T15:58:43+00:00

Our experience within the industry has led us to discover a wide range of properties where cavity wall insulation has proven to be problematic, including:

  • Properties where there are elevations that are exposed to the elements and partially effected by wind driven rain;
  • Timber framed properties;
  • Steel framed properties;
  • Properties where incorrectly fitted or poor quality rain water goods have been used;
  • Properties that have experienced crumbling mortar (which should have been re-pointed prior to cavity wall insulation being installed);
  • Properties where rising damp was already being experienced;
  • Certain properties where raked mortar joints are used;
  • Properties where the cavity wall space is either under a measurement of 40mm, or over a measurement of 150mm;
  • Properties where debris, mortar, broken bricks or rubble were left within the cavity.
Why are steel and timber framed properties not suitable for cavity wall insulation?2020-01-08T15:57:38+00:00

Steel framed homes are absolutely not suitable for cavity wall insulation; in fact often these properties, where cavity wall insulation is installed, have been unable to have a mortgage granted for them as the surveyors deem insulation a serious risk to the steel or timber frame. The reasoning behind this is that, if the insulation were to become damp, it could lead to the corrosion of the frame – ultimately over time making the building potentially unstable.

Similarly, timber framed properties could experience a rotting of the frame, what’s more both steel and timber frame properties require sufficient air circulation in order to avoid damp, rotting or corrosion

How do you survey to assess whether cavity wall insulation should be removed?2020-01-08T15:57:12+00:00

We have a wide range of non-invasive and invasive survey methods for assessing whether CWI extraction is required, including:
Non-invasive methods: Borescope inspection, Thermal Imagery and Moisture & Damp meters.
Invasive methods: Brick removal.

When does cavity wall insulation need to be removed?2020-01-08T15:55:08+00:00

Beyond incorrectly fitted or old and inefficient cavity wall insulation not performing, there are a number of other reasons that may mean your insulation should be removed and re-fitted. These include;

  • Where urea-formaldehyde insulation is in use;
  • Where there has been flood/water damage caused to the property;
  • Where the cavity wall insulation has been installed within an unsuitable building type such as a steel or timber framed property.
My home suffers from damp – is it due to poorly fitted cavity wall insulation?2020-01-08T15:54:32+00:00

Damp can certainly be caused by either incorrectly fitted insulation, or insulation that was simply installed a number of years ago. In the former case, there are a plethora of poor practises that could have led to damp issues (If you in the latter instance it could be that the old insulation has simply slumped down, leading to the revealing of cold spots and the consequent forming of condensation.

Why remove cavity wall insulation?2020-01-08T15:54:09+00:00

It is estimated that over 6 million properties around the UK have had cavity wall insulation installed. Of course, the energy efficiency and cost savings have made it very popular. However, not every building is suitable.

If the building is located in an area of the UK that has high exposure to wind and rain and wool type insulation has been used to fill the cavity, then it is likely that this will be causing damp in the property. One of the primary purposes of the cavity is to drain water away from the inner leaf of the brick, but if the cavity is filled with wool, this type of insulation can create a pathway for water to travel over the cavity and cause damp in the house.

We live on an island with a generally damp climate often exposed to high winds and even icy conditions.
This takes its toll on brick work which can lead to gaps opening up in bricks or pointing and water getting into the cavity itself. The whole point of insulation is to insulate. It stops air flow. The problem with this is that once it becomes wet, it is virtually impossible to dry out.

Instead, dampness and cold is drawn through the cavity into the inside of the property. You can see this if there are cold spots on walls in your home or unexplained patches of damp.

Not only can this create uncomfortable living conditions, but the prolonged damp will also rust wall ties, an integral structural part of the property which can eventually mean the inner and outer walls can actually separate.

What is cavity wall insulation?2020-01-08T15:53:05+00:00

Cavity wall insulation is an insulating material; commonly-used materials include mineral wool, polystyrene beads or foam that is inserted into the gap or cavity between the internal and external wall of a home.

Cavity wall insulation stores the heat within the inner walls, bouncing it back into the room and holding it for longer. This gives you a more even temperature and gets rid of the draughts that come down from the walls.

What is a cavity wall?2020-01-08T15:52:37+00:00

The external wall of a property is constructed of two (brick or block) walls, with a cavity (gap) of at least 50mm between. Metal ties join the two walls together. If your home was built after 1920, the chances are that its external walls are made of two layers with a gap or cavity in between them.
