Central Heating Services


There isn't one simple answer; having your boiler serviced or checked is beneficial any time of the year. 

Generally, you would want to have your boiler serviced in what is known as an off-peak period as prices are lower, there are fewer delays, and it gives you confidence for the coming off-peak periods or winter when your boiler goes through its toughest season.

It is recommended to do this on an average of once per year; so much so, it is an actual lawful requirement for landlords. We highly advise that your servicing shouldn't be less frequent than annually.

A broken-down boiler can lead to leaks of a gas known as carbon monoxide, almost undetectable due to the gas's colourless and odourless nature. 

Without regular servicing, there's a high chance you won't know you have a carbon monoxide leak until it's too late or you get very sick.

In the long run, fixing a faulty boiler is more costly than annual servicing. Annual servicing is great for breakdown prevention, saving you on repairs and part replacements.

Having your boiler annually serviced ensures safety, which is particularly important when keeping your families peace of mind. 

A faulty boiler is a hazardous and poisonous environment, especially for younger family members or pets. 

Annual services allow experts to pick up on these problems before they escalate, additionally saving you money in the long run. 

Having a perfectly working boiler will also increase efficiency, saving you money on your energy bills. More efficient boilers are cheaper to run and have less energy wastage.

As a landlord, you are legally required to service all your tenant's boilers annually.

The main difference between a plumber and a heating engineer is qualifications; a plumber isn't gas safe qualified. 

A plumber can fit and work with pipes such as radiators, thermostatic radiator valves, towel rails, power flushes, etc.

On the other hand, heating engineers can install boilers, service or repair said boilers, run new gas pipes, repair leakages, change radiators, install heating controls, etc.

As great as you are at DIY, without gas safe qualifications, installing a new boiler is not only dangerous but illegal. 

When hiring a gas sage engineer, you can always check their identification and find them on the register to ensure they are qualified to do the job you've paid them for.

While you can attempt to fix plumbing pipes yourself, the only consequence could be a water leak; consequences revolving boilers could be a full-blown explosion. 

Working with boilers is a perilous game, and even if you manage to perform the task illegally, gas might still be getting out, leading to people getting very sick or even death. This can leave you hospitalised or even in prison.

Underfloor Heating


This is highly dependent on whether you're constructing a new home or renovating an already constructed building. 

Another huge factor is whether you're running dry or wet systems; wet is generally more expensive to install but cheaper in the long run; this is the opposite for dry (3-4 times more on average). 

However, both, once installed, generally cheaper to run than other heating options annually.

In short, yes. Underfloor heating distributes heat more efficiently and uses radiant heating instead of radiators, which are inconsistent, leaving due to the nature of the heat it produces rising and falling. 

A room is generally hotter towards the radiator, especially the higher you go.

The further away you are, the floor is generally hotter while still not as hot as if you were closer to the radiator. It's hard to take comfort when some areas are overheated, and some are underheated. 

This inefficiency isn't economically effective, and you're paying more than you should for the less aesthetic option in your home.

Yes, however certain factors must be taken into account. While not exactly the optimum choice due to the nature of wood not being a great conductor of heat. 

Wooden floors will take longer to warm than, say, tile or stone and won't hold the heat for as long. It is also recommended that heat doesn't exceed 27 celsius due to warping. Luckily most homes only recommended 24 celsius at most.

Yes, although additional maintenance or adjustments may be necessary. 

Depending on the current situation of your home, a qualified engineer will be able to make this possible; even if you wish for all your heating to use the same boiler, an engineer can install a two-port valve, allowing you to control which heating option is operational.

Bathroom Design & Installation


On average, installing a new bathroom can cost anywhere between £1,500 to £7,500, with an average of £4,500. 

Varying factors include whether you're going for luxury, bespoke, having a bath and shower, etc.

  • Electrical work.
  • Plumbing work.
  • Special features.
  • Sizing/measurements.
  • Location.
  • State of the property and age.
  • Specialist requirements.

On average, a new bathroom will increase the value of your home by 4-5% of its original value; this is important when taking into account how much you're spending on the bathroom.

It all depends on how you personally value each factor. Adding a bathroom will increase the value of your home, but it won't always increase the value by the price you paid for it. If this is important to you, then these are factors worth estimating or consulting for.

Other factors include how much you need the additional bathroom or if it's just a luxury and how much of a benefit this luxury is to you personally. This will mean your monthly/annually bills will increase.

Solar Thermal Water Heating


Solar thermal heating, also known as solar heating systems, extract heat from the sun to heat your water. 

Solar thermal systems often work in tandem with other boilers to ensure you still have heat when the sun isn't out. They're a great eco-friendly alternative and cheaper on cost.

While more expensive to install, it is almost guaranteed you will save money in the long run. 

Factors concerning this are how optimal your system is, usage, how much sun you'll get in your location, and your backup system's cost.

Generally, solar thermal water can get hot enough to compete with any other heat option a house may include, however using this heat for electric showers, cold-fill dishwashers, or washing machines will quickly use up all of that heat, making it highly recommended you don't use solar thermal water for these appliances.

Solar thermal heating is mostly applied for water heating, such as throughout your home, swimming pools, or industrial purposes. Solar thermal heating has been applied domestically to homes for over a decade now and has heated many homes across the country.

However, it isn't recommended for heavy use or throughout the winter seasons, which is why a backup is always advisable. Solar thermal heating can generally carry most of your water heating loads throughout the summer season.

Yes, when there is sun, thermal energy is to be absorbed, just less so during winter. During these winter seasons, it is heavily advised you rely on other heating options available to you instead. 

There are fewer daylight hours combined with overcast or cloudy skies; you aren't left with much sun. Some heat will be provided; however, just not enough to carry most of the load.

Air Source Heat Pumps


Air source heat pumps gain their worth through:

    • A low carbon footprint
    • Cheaper energy bills
    • Eligibility for RHI
    • Heating and cooling options
    • Efficiency in low temperatures
    • Consistency throughout peaks in any season
    • Low maintenance
    • Long life span
    • Easy to install
    • Eco-efficient power options
    • No fuel storage necessary

    In short, no. A new gas or oil-fired heating system will generally be cheaper than an air source heat pump. Long answer, yes.  

    Monthly/Annually, an air source heat pump will considerably save you money in terms of bills compared to, say, gas or oil-fired heating system.

    It will always be beneficial to consult a qualified heat pump engineer on your home specifically, as this answer can vary; however, heat pumps can work with radiators.

    Yes, this is an option, although it is recommended your heat pump work in tandem with another boiler option to help through harsher conditions such as winter, where the heat pump may struggle. 

    However, if necessary, you can heat a house with just a heat pump.

    Ground Source Heat Pumps


    A more eco-friendly and occasionally cheaper alternative to your usual domestic boiler. 

    An external well sits outside your home on your property and will pump water up and down to heat your home.

    Ask about our  ground source heat pump installation.

    In a technical sense, yes. While the wells generate their heat/energy from the earth itself, the energy required to power the well itself isn't reliable as it still requires energy to operate. 

    Meaning you may be entitled to the renewable heat incentive scheme.

    Due to the nature of a heat pump being considerably larger than a boiler and can't sit within your home, a large amount of space is required for the system to operate.

    Once you have checked if you have enough space or are willing to give up the space required, access is the next concern; your property must be suitable for digging to allow the heat pump access below the ground.

    Ground source heat pumps generally provide lower temperatures than domestic boilers, meaning insulated homes are often recommended for this type of heating.

    Ground source heat pumps generally have two options - horizontal and vertical. The horizontal option is only around 1-2 metres deep and is more common when more land is available. 

    The vertical options are generally more expensive and are used when less space is available and are around 50-150 metres deep.

    Air Conditioning Maintenance


    Your air conditioner should be serviced annually at least, biannually if applicable. 

    The reasons for going to these measures are the increase in dependability, problems being caught early/fixed, consistent efficiency, no wastage, safety and eco-friendly benefits.

    Without proper servicing, you can expect breakdowns that are more costly than simple servicing or checkups, and this means repairs and possibly part replacements. 

    If not properly maintained, Worn AC units can become less efficient, meaning more wastage for you and less output than you'd expect.

    Air conditioners deal with air daily; without proper care, this air can become filthy due to build-up or the state your air conditioner is in. It is important for the health of yourself or others that the air circling the air conditioner is clean and safe to breathe in.
