Green Deal Scheme

upgrading your boiler to a more energy efficient boiler 

could save you up to £310 a year.

What is the Green Deal Schemes

Under the Green Deal, bill payers will be able to get energy efficiency improvements without having to front up the cash. Instead, businesses will provide the capital, getting their money back via the energy bill. At the heart of the offer is a simple rule: estimated savings on bills will always equal or exceed the cost of the work.

The Green Deal helps you make energy-saving improvements to your home and find the best way to pay for them.


The improvements that could save you the most energy depend on your home, but typical examples include:


  • insulation – eg solid wall, cavity wall or loft insulation
  • heating
  • draught-proofing
  • double glazing
  • renewable energy generation – eg solar panels or heat pumps


Here at Capital Design Build we are able to offer Green Deal for Heating


Green Deal fast facts


  1. The Green Deal is essentially a very cheap loan scheme to pay for energy-saving measures which will make the UK more energy-efficient.
  2. Why is this being done? Firstly, our homes suffer from a vast amount of heat loss. Secondly, Britain has ambitious targets for cutting carbon emissions, and the Green Deal is an important part of meeting these targets.
  3. The golden rule of the Green Deal is that the amount you save on your bills will always be greater than the cost of the energy-saving measures.
  4. The cost is absorbed into your future energy bills and consequently paid back over time.
  5. An estimated 26,000,000 homes could be eligible for Green Deal financing.

The Financial obligation

The green Deal the Green Deal differs from existing lending – it is not a conventional loan since the bill-payer is not liable for the full capital cost of the measures, only the charges due whilst you occupy  that property,

If the occupier moves out and ceases to be the bill-payer the financial obligation doesn’t move with as well but moves to the next bill payer: the charge is only paid whilst the benefits are enjoyed. In this way. The loan is paid back through the electricity bill over a 25-year period.

Who Qualifies

To qualify for the Green Deal, expected savings in typical properties consuming a normal amount
of energy must be equal to or greater than the cost of the measure. However, actual cash
savings cannot be guaranteed by government since no-one except individuals and businesses

themselves can control how much energy they actually consume in their own property. We will give energy users advice on how to change behaviour to maximise the benefits of better insulated, less wasteful properties.

Can I still switch energy providers with the Green Deal?

Yes! Your Green Deal will be fully transferable between suppliers as it is a fixed amount, you don’t need a special Green Deal energy supplier.

What if I can’t pay anymore?

If you default on Green Deal payments you will be treated in the same way as customers who default on their energy bills. You could be disconnected.

The Cash Back Scheme

Please read the Green Deal Cashback quick guide for up to date information on the scheme including new Cashback rates. Green Deal Cashback is a limited offer while funds last. Cashback amounts may reduce.

How do I book an assessment

Only registered Green Deal Installers, Green Deal Advisers and Green Deal Providers can be involved in this scheme and appointments for the assessor are chargeable.

  • The Assessor

An adviser will attend the property and carry out a full assessment and provide clear information and advice.

During the assessment visit

Our adviser will attend the property and carry out a full assessment and provide clear information and advice.

  • The assessor will produce a Green Deal advice report. This is made up of an Energy Performance Certificate (EPC), which ranks your home’s energy efficiency on a scale of A to G, and an Occupancy Assessment, which assesses how you use energy in your home.
  • To make the assessment the assessor may ask questions including how many people live in your home, what energy efficient measures are already installed and whether your home is in a conservation area or built in a non-traditional way.
  • As Capital Design Build is part of a company that also provides Green Deal measures, We may offer you a quote for installing a new boiler.  and our assessor will make it clear when the role is changed from impartial assessor to salesperson.

You are not obliged to accept the terms of any quote offered on that day

After the assessment visit

  • The Provider

The Assessors report is submitted to a provider who will make a decision for the Green Deal Scheme based on the assessment. Once acceptance has been given the applicant will be contacted and arrangements will be made for the installer to carry out the works.


  • The Installer

The installer will attend the property and carryout a site survey and book the installation of the new boiler.


For more advice or if you have any problems with your assessment, call the Energy Saving Advice Service on 0300 123 1234.





Key boiler considerations

Key considerations when choosing a boiler

Key considerations when choosing a boiler

First of all, you need to decide which type of replacement boiler to go for, consider:


pound sign What is your budget?

Decide how much you want to spend and stick to it.


boiler situatedWhere will the new boiler be situated? 
Note that a new condensing boiler emits  a water vapour.   This  could mean that you may want to reconsider the location of your flue as it could prove a nuisance in its present location.
What level of demand will there be on the boiler?
Think about how many people need to use hot water at the same time.    For example a larger family all getting ready for work or school at the same time in the morning, using more than one shower at any one time.   Our engineer will need to make sure that the boiler is of a specification that can cope with the demand that will be placed on it.

Bleed a Radiator

How To Bleed Your Radiator

You will need

  • 1 Tea towel
  • 1 Radiator key

Turn off the heating


Ensure that the central heating is switched off before bleeding as this can introduce more air into the system.

Open valves

Ensure both valves at the bottom of the radiator are open.




Using the radiator key, insert it into the bleed screw at the top of the radiator.



Catch drips

  • Have some kitchen towel or cloth to catch any drips.
  • Slowly turn the key anti-clockwise. About half a turn. You should hear hissing. This is the air being forced out by the water.
  • As soon as the water squirts through the screw re tighten and ensure nothing is leaking.
  • Repeat on all radiators
  • Finally, you may need to top up the boiler if necessary.



Water Gurgling

Water Gurgling

If you can hear water gurgling through the central heating system, then it is a clear sign that you have got air in the radiators. This problem can be easily resolved by bleeding the radiators, see our advice on how to bleed a radiator below. If after bleeding the radiators you’ve still got gurgling sounds then there might be a deeper problem so call Capital.

How to Bleed the Radiator 



Boiler Leak

My boiler is leaking

  • firstly check to see where the leak is coming from look along the piping
  • use a cup etc to collect the water and note how much is being collected within a period of time
  • look for joints in the piping and tighten where necessary
  • keep a check on the pressure of the boiler
  • if the water leak is excessive turn off your heating and call Capital.

Boiler Faults

No Hot Water

No Hot Water but Central Heating is alright

  • Especially in cold weather rather than turning the taps on full turn them so they run slower
  • check the settings and  timer on the boiler make sure set to hot water
  • check that the boiler is switched on
  • check the water pressure and turn up if necessary


With the boiler set to CH and water on the timer setting turn a hot tap on and listen for a click at the boiler and feel if water is going through the pipes is it getting hot. No click? but if you only have hot water to the central heating pipes The diverter valve is not working correctly and needs service or replacement.


No Central Heating

Hot water is alright but no central heating


Check that the thermostat hasn’t been set too low ( the boiler will only work if the heating is set higher than the room temperature





Check that the timer has not been set to come on at 4 in the morning

instead of 4 in the afternoon.







Check that the batteries are working and change if necessary








Make sure that the selector switch is ON and in heating position
