In Great Britan, on April 1st 2009, the Gas Safe Register™ replaced CORGI gas registration CORGI was set up in 1970 as the as the 'Confederation for the Registration of Gas Installers'. CORGI was set up in 1970 in response to the 1968 'Ronan Point' accident, when a gas explosion caused the partial collapse of a new tower block, resulting in 4 deaths and numerous injuries. This accident was caused by a faulty gas installation, and it was from this that CORGI was created.Initially, gas installers only needed to become CORGI registered on a voluntary basis. However, in 1991, the HSE (Health and Safety Executive) asked CORGI to maintain a register of competent gas installers in the UK. As a result, CORGI now stands for 'Council for Registered Gas Installers'.On April 1st 2009, the Gas Safe Register replaced CORGI. The register is designed to protect you, your family and your property from dangerous and unsafe gas works. By law, anyone carrying out work on gas installations and appliances MUST be on the Gas Safe Register.

 1  Older type boilers waste energy; consider replacing yours with a modern condensing boiler, which converts more than 88% of fuel into heat. This could save you 30%, or around £150-£180 on your average annual heating bill.

 2  Install a timer on your heating system - it is far more cost efficient to have your boiler coming on an off when required rather than having it continuously running.

 3   Have thermostatic radiator valves fitted to all your radiators to control individual room temperatures or switch heat off completely in certain parts of your house.

 4  Make sure your heating system is equipped with a room thermostat - cutting room temperature by one degree will save 5% annually on your heating bill.

 5  Regular servicing of your boiler is vital for safety, but significantly a well maintained heating system will be more efficient and cost less to run.

 6   Make sure all your heating system's pipes are properly lagged and insulated so energy is not wasted through heat loss.

Please feel free to Contact Us at any time for free advice or an operative can check how cost  efficient your system is and recommend improvements, where necessary.



SEDBUK stands for 'Seasonal Efficiency of a Domestic Boiler in the UK', and provides a fair comparison of the energy performance of different boilers. -->What difference can an energy efficient boiler make ? 

  •  It produces less CO2
  • It will consume less fuel 
  •  It can therefore significantly reduce gas heating costs

 How is a SEDBUK rating calculated ?  SEDBUK refers to the average annual efficiency achieved in typical domestic conditions, and the rating is calculated using:

  • The pattern of usage and typical domestic usage patterns
  • The UK climate 
  • Boiler type
  • Ignition
  • Fuel used
  • Internal store size

Step One:  A SEDBUK rating assesses what percentage of the fuel that the boiler consumes is converted into heat. Step Two: That percentage is given a rating using a scale from 'A' (at the highest level of efficiency) to 'G'.It's a way of estimating annual fuel running costs, and all new boilers should be SEDBUK Band A or B rated except in some specific circumstances.High efficiency range 

  • Baxi Platinum Combi HE A
  • Baxi Duo-tec Combi HE A
  • Baxi Solo HE
  • Baxi Megaflo 
  •  System HE A
  • form part of Baxi's high efficiency range. 
  •  They carry a SEDBUK Band A rating and are

 amongst the most efficient boilers on the UK market.

Older combination boilers often have a lower flow rate than newer models. This can be made worse by a build up of scale in the boiler over time. In this situation we suggest that you have an expert check your boiler and central heating system. If you would like us to investigate this or any other problem with your boiler then please feeel free to Contact Us and arrange for one of our fully qualified engineers to take a look.

This usually means that your central heating system is incorrectly balanced. This results in the hot water not flowing evenly to each radiator. We suggest that you have an expert check your central heating system.If you would like us to investigate this or any other Central Heating problem for you then please feel free to Contact Us and let one of our fully qualified engineers take a look for you.

This usually means that there is air trapped in the top of your radiator. You may want to try to bleed the radiator to release the air. However, we suggest that you have your central heating checked by an expert in case there are any underlying system problems.So please feel free to Contact Us and let one of our fully qualified engineers take a closer look.

This usually means you have a sludge build up in the bottom of the radiator. This can be resolved by power flushing the system. However, before taking any action we recommend that you seek expert advice to identify the cause of the sludge first, for example you may have a water leak. So why not contact us on one of the above for some advice.

A Thermostatic Radiator Valve allows you to control the temperature in individual rooms around your home. It can also help you reduce your fuel bills by automatically adjusting the radiator temperature once your room has reached its desired level.

You can save up to 40% on your heating bills but this depends on the size of your home, how often you use your heating system what insulation you have in your home and the type of boiler you have fitted. We offer free site surveys where we can assess your requirements and give you a more accurate idea of what you could save. So feel free to Contact Us to arrange a survey today.

The installation of a new system does involve new pipe work being fitted and heating controls being installed. We aim to ensure that disruption in your home is kept to a minimum, we will keep you updated on our progress at all times.

We recommend that you have your boiler serviced each year. This will ensure that it is working at maximum performance and safety. Contact Us today to arrange for one of our fully qualified engineers to service your boiler.

To make sure that you get the right boiler and central heating system for your home you can Contact Us to arrange for one of our fully qualified adviser's to visit you and give you a free, detailed estimate, which is tailored specifically to your needs.
