ECO is part of the Green Deal funding option which has been invested in by the 'Big six' Energy companies. They have committed to a fund of £1.3 billion per year and are available for most properties.

Under ECO, medium and larger energy suppliers fund the installation of energy efficiency measures in British households. ... The obligated energy suppliers work with installers to introduce certain efficiency measures into your home, such as loft or wall insulation, or heating measures.

The government's response to the Energy Company Obligation ( ECO3 ) consultation sets out the policy of the scheme that will run from Autumn 2018 until March 2022. The scheme delivers energy efficiency and heating measures to homes in Great Britain.

1) Fill out our online form. It’s quick and only takes a couple of minutes.
2) Our friendly service team will call you to confirm your benefits.
3) A qualified surveyor will visit your home to approve your grant and fit a Free Hive Thermostat Controller.
4) A Gas Safe registered installer will install your new boiler.

A more energy efficient home uses less energy, therefore saving money on energy bills. You will also be helping to reduce carbon emissions and doing your bit for the environment.

No. Any Eco funding used for your Home is a grant and does not need to be paid back. ECO is not available for all of the measures and sometimes will depend on certain eligibility criteria. If you have any questions please contact us on 01942369260 

No. Any ECO funding used for your free boiler also covers the installation of the boiler and the removal of you old one. However this is subject to a non obligation survey and in some cases a contribution maybe required. If unsure please contact us.

Replace. A repair can sometimes be as expensive as a brand new boiler. And you could easily have more problems with a repaired boiler further down the line. A brand new boiler is usually more efficient and more reliable. Your new boiler will be covered by warranty too – so if it breaks, the manufacturer will repair it with no extra charge.

The costs for: a brand new A-rated boiler, a brand new flue, all the right fixtures, fittings and safety attachments, installation from a Gas Safe Registered engineer would traditionally set you back between £2,500 and £4,000. We can offer a new a rated boiler, installed and with warranty for free if you qualify for the scheme. Are all your installers fully qualified? All of our installers are Gas Safe Registered with years of experience. You can be fully assured that you will receive the most professional service from us.

Yes all our boilers come with a warranty of up to two years.

No, our engineers have years of experience and will make sure all surfaces are protected and will provide work in a clean and tidy environment.

Yes. Before your installer arrives, clear away any clutter around the boiler – especially valuables and things that break easily – and make sure the boiler is easy to access. This just makes the installation run a lot smoother and quicker.

A flue is a pipe, like a chimney, that carries waste from the boiler outside. You can see your flue exit (the part of the flue that comes out of your house) on the wall or roof of your home. Flues can either be square or round in shape. If the flue is less than two metres off the ground, or underneath a carport or shelter, it'll be covered by a guard. This looks like a piece of wire mesh covering the end of the flue.

Yes. We do a Chemical Flush – a hot flush and dose. We'll put a cleaner into your system, flushing it around using the boiler. We'll keep going until it's clean. Once the system is up to temperature, it's drained and refilled with clean water. Finally, an inhibitor is added to the water to protect the system.

Understanding Boilers

We generally fit like for like under the scheme, from a large range of different suppliers which include but not limited to Worcester, Viessmann, Glow worm and Ideal.

If you meet the benefits related criteria, and your current boiler is at least 6 years old if it
is a combi boiler and 4 years if it is a regular boiler.

The Energy Saving Trust says: If you replace your old model with an A-rated boiler and set of heating controls (you can even operate it remotely via an app on your phone) you could save about £340 and 1,500kg of carbon monoxide a year.

A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.

They are also very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump.

  • Compact sizes make combi boilers perfect for smaller properties
  • Ideal where there is little or no loft space
  • No need for a hot water cylinder allows increased living space
  • No cold water storage tank frees up a loft for conversion
  • No risk of loft pipework freezing
  • Less pipework in the home makes installation typically cheaper

System boilers require a cylinder for storing hot water, however the major heating and hot water system components are built into the boiler itself, making it quicker and easier to install. In addition, there is no need for a tank in the loft, so it can be an option in a home with little or no loft space or where the space is earmarked for a conversion.

These boilers are also compatible with solar water heating systems, which deliver environmental benefits as well as lower energy bills.

  • Ideal for homes with more than one bathroom
  • Constant supply of hot water to any number of taps at the same time
  • No need for a loft tank, freeing up space and eliminating worries about leaks or frost damage
  • Economical to run
  • Built-in components makes installation quicker and neater

Regular boilers (sometimes known as traditional, conventional or heat only boilers) are ideally suited to homes that already have a traditional heating and hot water system which is linked to a separate hot water cylinder. These boilers also need a cold water storage tank in the loft to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.

A regular boiler may be the best option for replacing an existing boiler if the property has an older radiator system, as it might not be able to cope with the higher water pressure that is delivered by system or combi boilers.

  • Perfect for homes where a lot of hot water is used at the same time
  • Ideal where there are two or more bathrooms
  • A good option in areas where water pressure is low
  • Compatible with solar water heating systems for a lower carbon footprint and lower energy costs
    Important terms and definitions

Term Definition

The Erp – Energy related products – Label tells you how efficiently a boiler (or another appliance like a fridge or a washing machine) uses energy. It's designed to help you choose the right appliance and pay less in energy bills. The label rates products from A+++ to G. A+++ is the most efficient boiler you can get. It also tells you how loud the appliance is in decibels and how much heat it outputs in kilowatts. All of the boilers we use are rated A for efficiency.

To check your boiler's pressure, you need to locate the pressure gauge on your boiler. If there is the correct amount of pressure in your system, the needle should be between 1 and 2 bar. This area is usually designated in green. Below 1 and greater than 2 is in red, indicating critical zones.

Changes to government legislation and technology advances in boiler design has driven boiler designs to condense to ensure as much heat as possible is converted into useful heat for your home. By condensing, your boiler will ensure at least 90p in every £1 you spend on gas or oil will be converted into heat for your home comfort.

Along with heat, when gas or oil is burned within your boiler condensation is also created. This can be seen in the gases which plume out from the boiler, something that is especially noticeable in cold weather. However in addition to this condensate being discharged in the air, condensate also collects inside the boiler and is drained away either inside or outside your home. This is safe and nothing to worry about.

However if your condensate pipe has not been terminated according to our installation guidelines, there is a chance it could freeze in severe weather conditions. Please contact your installer in this instance or see here for advice on how to rectify this yourself

Quoted for Combi boilers, a flow rate represents how many litres of hot water comes out of the tap in a minute. Your flow rate is determined by the amount (and pressure) of water that is entering your property from the water main and the ability of the boiler to heat that water to the temperature you have set. The more powerful a boiler is (represented in kW), the faster the boiler will be able to heat the water coming into your home.

However it is important to recognise a high kW output will not always increase your flow rate. If you have 10 litres per minute coming into your property, you will only be able to receive 10 litres per min of hot water. For example having a boiler that has a maximum flow rate of 14 litres per min will not increase the amount of hot water you receive, if you only have 10 litres per min coming into your boiler.

Gas Safe Accreditation is the hallmark for gas safety in the UK. An installer must be on the Gas Safe Register to be legally allowed to work on your boiler or any other gas appliances in your home. www.gassaferegister.co.uk

A system filter is a specifically designed unit which aims to remove and filter magnetic and non-magnetic contaminants from your central heating system before they reach your boiler. Building Regulations always recommends a system filter be fitted to your heating system pipes prior your boiler to prevent any damage to key components.

Over time oxygen in the heating system can react with the metals and components of a heating system such as radiators to produce magnetite (rust) particles, which becomes suspended in your system water. This process and the build-up of other chemicals (such as lime scale) can quickly cause blockages and damage key components within the boiler and system. To prevent this a process of thorough system flushing should take place when fitting a new boiler onto an old heating system. This process involves forcing old system water out of the heating system, whilst simultaneously filtering the system until all of the old water and contaminants are removed. Finally inhibitor and a system filter is added to prevent any future sludge and contaminants from building up.

Thermostatic Radiator Valves (TRV’s) enable you to control the individual temperature of each room in your home, and can be adjusted to the comfort levels you want. The higher the number selected on the TRV, the hotter the radiator and warmer the room. Please note a TRV should not be fitted on a radiator in the same room as a room thermostat.

Weather Compensation is a feature which is programmed into selected boiler controls and Greenstar I Combi boilers. Designed to improve comfort, the feature automatically adjusts the temperature of your system to compensate for the weather outside. E.g. if the temperature outside drops, your radiators will run hotter, whilst if the temperature increases the boiler produce less heat, reducing your running costs.
