Choosing British Gas

At British Gas our team of experts fits more boilers and central heating systems than anyone else in the UK.


Here’s how we do it.


Understanding your needs


Your first step is to book an appointment for us to come and visit you – you can do this online or by giving us a call.


Because every home is different, we’ll send out one of our Heating Advisors to provide a quote in your home. 


We can visit at a time that suits you – even if that’s an evening or a weekend.


The appointment will last about one and a half hours after which you’ll receive an itemised quotation. There’s no cost for this and no obligation.


They’ll start with a walk around to understand your existing setup and do some basic checks and tests to determine the best heating solution for you, but also to ensure your home is safe.


They’ll talk you through your options and help you make the best decisions for your home.


Our heating advisor will also carry out an efficiency assessment on your home so that they can discuss any potential energy savings with you. We only install the most energy-efficient boilers that are A-rated and could save you of up to £340 a year on your energy bills.


Our Heating Advisors are experts on more than just boilers.


For example, you may be eligible to be upgraded to smart meters.  This means you will be able to see exactly how much energy you’re using, as you use it, in pounds and pence, and receive accurate bills without having to submit meter reads.


And HIVE active heating allows you to control your heating and hot water from your phone, tablet or computer, so if your plans change – or the weather does - you can adjust your heating rather than waste money.


They can also talk you through the benefits of insulation, solar PV and make sure you’re on the best energy tariff for your home.


If you’re happy to go ahead with the quote we’ll talk you through the different ways you could choose to pay.  And with our partners at Barclays, you could even go ahead with no deposit or upfront cost and fixed monthly repayments.


Our Heating Advisor will also let you know about any Government Schemes that may suitable for you.


Your advisor will then start making the delivery and installation bookings for you, all of which will be confirmed by text or email.


And remember, the price we give you is the price you pay, no matter what.


Your Installation


Your Heating Advisor will leave you with a number for your dedicated customer support team.  They’ll be your main point of contact from now on if you have any questions.


The next step is delivery of the boiler on the agreed date.  We try and do this the day before installation so our Engineer can start work as soon as they arrive. You’ll get a call the day before to confirm and a call from the driver when he’s on his way.


You’ll also get a call from your installation engineer the day before to introduce themselves and let you know when they’ll be arriving.


Most installations take between one and two days and our number one priority is the safety and care of your home.


As soon as we arrive we’ll explain exactly how we’re going to do the job, make sure you’re happy and then discuss any safety points you need to be aware of. 

 

If you want to go out and leave us to it – that’s fine. 


We’ll then lay dustsheets and move any pieces of furniture we need to.


Once installation is complete, we’ll clear up any mess with our own vacuum cleaner and leave your house as we found it.


We’ll then go through heating controls and how everything works to make sure you’re happy before we say goodbye.


Looking after your world


Your engineer will give you a call a few days later to make sure  everything’s going well, but remember, you can always call your customer support team.

Step 3 – Arrange an installation

  • If you decide to go ahead, your Heating Adviser will arrange a convenient installation date.
  • You’ll receive contact details for our Customer Support Team, should you need to get in touch.

Step 4 - Your new boiler installation

  • Your Engineer will call beforehand to introduce themselves.
  • Before they start, they will run you through some important safety information.
  • Once your installation is complete, your Engineer will give you a full explanation of how to use your new boiler and controls.
  • They’ll leave your home clean and tidy, and will arrange the disposal of all waste including the old boiler.

Reading Homeowner
All materials were delivered as arranged. All work was carried out as quoted and everything was left clean and tidy at the end of the installation. All flooring and worktops were covered where possible. I am a pensioner and the different engineers were all very affable and helpful where decisions had to be made which means a lot to someone living alone. I hasten to add that I did supply endless cups of tea (or cold drinks) to keep everyone happy!!! The engineer who was 'in charge' of the installation phoned me next day to make sure I did not have any problems.

Stourbridge Homeowner
No discussion took part as to which boilers were available. We were told that the boiler would be better than our last one which is not the case. (May be more efficient). Hot water takes a very long time to reach the tap, let alone how much water is wasted getting to it. At the moment we don't use the hot tap as it takes too long to wait for it. My old water boiler was far quicker. New smart meter fitted but not registering usage at offices or on handset so can't see how much gas is being used by appliances as advertised, only electric. Several phone calls made (at my expense) but nothing done about it.

W e are delighted with the boiler and we are already feeling a difference.
I would have liked a fuller explanation from the person dealing with the
electrics.
