Our boiler engineers have been providing boiler installations throughout West London, Ealing, Hanwell, Harrow, Kingston, Wembley and Middlesex since 1993.

Many of our new customers have been referred to us by existing customers who have experienced the quality of our boiler installations work.

You will be interested to know that we guarantee to beat British Gas prices on all of our plumbing services and will give you £150 in the unlikely event that we can't. It's all part of the guarantee that we offer to all of our customers.

We also provide boiler repairs and boiler servicing. Please see these respective pages for more information.

Assessing your boiler installation needs

If you/we have identified that you definitely need a new boiler system (rather than repairs being sufficient/cost-effective) then an appointment can be made at your convenience. We will survey your current boiler installation, discuss your requirements with you, and will typically look to change your old boiler to an A-rated combination boiler, or an A-rated system boiler, which will save on your energy bills.

There is no charge for us to discuss your needs and provide you with a quotation.

Wide range of boiler systems

We will install the type of boiler system that perfectly matches your requirements. Below you can see the range of boiler manufacturers that we can choose from to provide the solution that's right for you.

Typical installation costs

While every new boiler installation is unique and so costs will differ, typical costs of boiler installations we provide are as follows:

Unvented Hot water System And Boiler £3,000
Combi-boiler: between £1,500 and £1,900
Systems boiler: between £1,400 and £2,000

Financial Assistance

You may be eligible for a Warm Front grant to fund all of your boiler installation. Please see our page about warm front grants.



Boiler installation process

  1. After your acceptance of our quotation, a date will be agreed for the work to commence.
  2. Our heating engineers will arrive and install your new boiler system, which takes between one to two days.
  3. Before fitting the new boiler the old system will be powerflushed and cleaned. A MagnaClean will be fitted to the system as standard.
  4. The new boiler will be commissioned and an analyser will be used to set the boiler to manufacturers instructions.
  5. On completion the engineers will explain to you how the new boiler will operate.
  6. Our engineers will remove the old boiler, leaving your property clean and tidy.
  7. All paperwork and guarantees will be issued to you and your boiler will then be registered online with Gas Safe. We invoice all our work after the boiler installation is complete and there are no upfront payments required.

Our Guarantee

All our boiler installations are guaranteed for two to six years, depending on which make of boiler you have installed. Most of our customers have a six year guarantee.

All guarantees are subject to annual service by our own heating engineers. On completion of your installation you will be added to our database and a yearly service reminder will be sent to you automatically.

We can offer up to 6 years guarantee because experience shows us that a boiler that is serviced each year will significantly outlast a boiler that isn't properly maintained.

Boiler installation testimonials

We are Gas Safe registered heating engineers and our ongoing success relies mainly on positive word of mouth from happy customers to new potential customers. We have included just a few testimonials below to show you what our customers say about our boiler installation service.

Your engineer carried out our boiler installation to our complete satisfaction. He was very punctual and was very helpful and professional. They great thing was they don't make a right old mess of were they work, we have had many bad experiences.

He worked very hard during the job and fully explained how the boiler system worked. I would use your company again.


Mr N.S Brar, Wembley  

Brilliant - said exactly what he was going to do - worked around difficulty caused by outside stopcock needing to be replaced (by Water Board). (Plumbing works - Installation of new Gas Boiler Water Tank & Taps following major water leak).


Mrs Rodriguez, Harrow  

Service received at short notice was excellent. (Gas/Plumbing works - New Boiler installation).


Mr & Mrs Saunders, Kingston  

After the issue with the cowboy plumber who didn't do what they said they would, your service was excellent. Before we'd contacted you we had 5 days without any hot water so it was a joy to get the new boiler up and running within a day of speaking to you. Never before has a shower felt so welcome!
