 Trustindex verifies that the original source of the review is Google. Jason did a perfect job upgrading our bathroom with his apprentice. He arrived at the time he said he would and kept me informed with what he was doing. His workmanship was perfect and the job was done very quickly. I will use Jason again and would recommend to anyone.

 Trustindex verifies that the original source of the review is Google. Fully recommended; we had a replacement bath put in, we wanted to retain the existing tiles, which were carefully removed and re-used to fit around the new bath / shape. All work was caried out professionally, with clear communication. Couldn't be happier. In addition, we have used them several times for other work, which has also been completed to the standards we expected.

 Trustindex verifies that the original source of the review is Google. Jason and his team done a fantastic job on my new bathroom. I needed a Toto toilet installed with as little disruption as possible. I went home back to Hong Kong for a month and left Jason my keys. We was in contact most days and when I came back the flat was spotless and tidy！ Highly recommend !

 Trustindex verifies that the original source of the review is Google. Boiler, downstairs toilet & new bathroom!
Jason fitted a new boiler. This involved moving location of current boiler. An exceptionally neat job with little disruption. Was so impressed with the workmanship and professionalism that decided on a downstairs loo. Jason did a brilliant job. I then decided to have my main bathroom completely redesigned. Jason handled this brilliantly and again, exceeded all expectations! He did an absolutely amazing transformation and both him and Tom were a pleasure to have around. They were both professional, reliable and extremely hardworking. Cannot recommend them enough! Well done boys!

 Trustindex verifies that the original source of the review is Google. I needed a couple new radiators installed and that required a bit of pipe work done. Jason and the crew came over and were very accommodating as I was in the middle of a refurb. Will certainly recommend him to family and friends 👍

 Trustindex verifies that the original source of the review is Google. Jason was amazing from the very first phone call. He helped us design a completely new layout for turning the horrible wet room in our new home, into a bathroom, and the outcome absolutely blew us away. He and his team worked nonstop and kept everything spotless throughout the entire process. I really couldn't recommend Jason and JplumB enough and I think the transformation and finish speak for itself! Unbelievable from start to finish!

How Much Does a New Boiler Cost?

One of the most common questions we get is: how much is a new boiler?

The cost of a new boiler depends on several factors, including:

The type of boiler (combi, system, conventional)
The size/output required for your home
Whether you’re replacing like-for-like or switching systems
The brand and warranty length
Any changes needed to pipework, controls or flues

Typical prices start from:

Combi boiler installation: from £1,800
System boiler installation: from £2,200
Conventional boiler installation: from £2,500

We’ll always provide a fixed, transparent quote — no hidden extras, and no generic online pricing that changes on the day.

Gas Boiler Installation by Trusted Engineers

We install a full range of gas boilers from the UK’s most trusted brands — including Vaillant, Worcester Bosch, Ideal, Glow-worm and Baxi. All installations are handled by our Gas Safe engineers, with complete documentation and warranty registration included.

You’ll receive:

Full removal of your old boiler
Professional installation of the new boiler
Flue and condensate pipe setup
System pressure testing and balancing
Smart thermostat or manual control installation
Warranty paperwork and commissioning certificate
Clean-up and full user handover

We don’t cut corners, and we’re always on hand to answer your questions after the job is complete.

Why Upgrade to a New Boiler?

If your current boiler is more than 10–15 years old, a new model could save you hundreds per year on gas bills — while reducing the risk of breakdowns.

Benefits of a new boiler include:

Better energy efficiency (A-rated systems)
Quieter and smoother operation
Compact designs that save space
Compatibility with smart controls and thermostats
Improved heating speed and water pressure
Lower carbon emissions and improved EPC rating

Most new boilers come with warranties of 7–10 years when installed by a certified installer — giving you peace of mind for the long term.

Combi, System or Regular? We’ll Help You Choose

We install all types of boilers and help you understand the pros and cons of each:

Combi boilers – provide hot water on demand, ideal for smaller homes with one bathroom
System boilers – store hot water in a cylinder, perfect for properties with multiple bathrooms
Regular (conventional) boilers – use cold water tanks and hot water cylinders, suited to large homes or those with existing setups

We’ll explain which system makes most sense for your home layout, water usage and future plans.

Quick Installation Times, No Stress

Once you’ve chosen your new boiler, we can usually install it within 3–5 working days — or sooner in urgent situations. We work quickly but carefully, protecting your property and minimising disruption throughout.

We handle:

Scheduling and planning
Ordering and delivering the new boiler
Coordinating any required electrical work
Completing flue or gas line modifications
Pressure testing, flushing and final checks

In most cases, installation takes 1–2 days, depending on the complexity of the job.

FAQs – New Boilers

What’s the best type of boiler for my home?

It depends on your household size, number of bathrooms, and water usage. We’ll assess your setup and recommend the best option.

How quickly can you install a new boiler?

Usually within 3–5 working days. Emergency installations may be possible faster — just ask.

Can you provide a quote before visiting?

We can give rough guidance by phone or email, but accurate pricing requires a site survey to assess layout, access and technical details.

Will I need to upgrade my pipework?

Not always. We’ll inspect your current system and only recommend pipework changes if needed for safety, efficiency or compatibility.

Do you register the warranty?

Yes — we register your boiler with the manufacturer and provide all certificates and paperwork.
