Today I had a replacement boiler installed by Janson and Dan. They arrived on time (with a pre-arrival message to say they were en route) and the installation took just over half a day, impressive.
Incredibly professional, tidy, and efficient from start to finish.
Highly recommended if you want quality work without a headache.

Response from the owner:Thank you, Mark. We're thrilled Janson and Dan provided a punctual, tidy, and efficient installation and appreciate you taking the time to recommend us. If you need any future servicing or have questions about your new boiler, please get in touch.

Just had a new boiler installed by Blackpool Boiler Installations. The whole process was handled efficiently and was quite painless from start to finish. Jason did an excellent job with the installation (very neat pipework, always ready to answer my questions and minimal disruption to the house). Dan helpfully assisted with the commissioning and the boiler is up and running nicely. I wouldn’t hesitate to recommend BBI.

Response from the owner:Thank you for your kind review, Peter. We're delighted the installation was efficient and painless and that Jason’s neat pipework and clear answers, along with Dan’s help during commissioning, got your boiler running smoothly. We’ll be sure to pass your compliments on to Jason and Dan. We appreciate the recommendation and are here if you need anything further.

Many thanks to Jason who removed my [16 year old] boiler and installed a new combi-boiler on Friday. Many thanks too to Dan who serviced my gas cooker and my two gas fires. No drama. I'm a repeat customer and I would also like to thank the office staff for their 'reminder email(s)' prompting me that the service was due soon, the detailed invoice and providing Jason with the written binder of clear instructions on how to use the timer - and again to Jason for his tuition and advice on setting up the 'system times and temperatures'. Thank you, James Turley.

Response from the owner:Thank you so much for your kind review, James. We’re delighted Jason and Dan provided smooth installation and servicing, and that our reminder emails, detailed invoice, and written instructions were helpful. I’ll pass your thanks on to Jason, Dan and our office team. We appreciate your continued trust as a repeat customer and look forward to helping you again.

Fantastic job by Jason and BBI. Had a radiator installed, boiler service and gas fire capped off.
Arrived bang on time, got a handy text before with ETA and I was able to track.
Very informative and friendly. Previous boiler installer had messed up wiring but Jason sorted it and made sure everything was put right and working before he left. Would definitely recommend!

Response from the owner:Thanks Robert, we're delighted Jason and the BBI team provided such a positive experience with your radiator installation, boiler service and gas fire capping. It's great to hear he arrived on time, kept you updated with an ETA and sorted the wiring issue left by the previous installer. Your recommendation means a lot to us and we'll pass your kind words on to Jason. Thank you for choosing BBI.

Why is there sludge in my radiators?

The sludge in your radiators is a mixture of rust fragments that break off from your pipework, radiators and soldered joints. It can also be made up of dust particles that accumulate over time. Even if your radiator was installed by a professional, this buildup is inevitable given enough time.

How often will my radiators need a power flush?

Every 5-6 years, there’s a chance that the sludge in your radiators will build up to a point where it affects your system. This is why we recommend a full system flush every 5-6 years, to make sure your central heating system works as intended.

Why do I need a power flush?

If you want to safeguard your radiators – a power flush is a handy process that helps to improve a few key aspects of your heating system. These include:

Heating efficiency – you can expect lower bills annually after a power flush!
Lifespan – stop issues before they occur to extend the lifespan of your heating system.

How long does a power flush take?

How long a system flush takes can vary, depending on the size of your central heating system, as well as how dirty your system is. It’s generally around five or six hours.
