Boiler Installers for AL2

Replacing the Original Boiler

A lot of the boilers we are asked to replace in the area were fitted when the house was built. At Napsbury Park, the homes and apartments created on the former hospital site from around the turn of the millennium came with boilers that are now well into their second decade. Parts are getting harder to find and efficiency has dropped, so owners are starting to plan replacements before a winter breakdown forces the issue.

In the older parts of the village, around the High Street and the River Colne, the picture is more varied, with conventional systems, cylinders and boilers that have been swapped several times over the years.

If you live in an apartment, the flue position and any changes to the outside of the building may need sign-off from the managing agent, so it is worth asking early. For other work locally, see our London Colney plumbing and heating page.

What to Think About Before Replacing

These points come up again and again when replacing a first-generation boiler.

Like-for-Like or Upgrade: If the original combi suited you, a modern combi in the same position is usually the simplest choice.
Apartment Flues: Flats often have tight rules on flue position. We work within them and help you get approval from the managing agent.
System Boilers in Larger Homes: Bigger Napsbury Park houses with several bathrooms may suit a system boiler and unvented cylinder better than another combi.
Clean Before Connecting: An old system can hold sludge that would damage a new boiler, so we clean it and fit a filter as part of the job.
Hard Water: Local water is hard, so scale protection is fitted where the regulations require it.

Signs Your Original Boiler Is Near the End

A boiler that has been in since the house was built usually starts to show its age in these ways.

Losing Pressure

An older combi that needs topping up regularly often has a failing expansion vessel or a slow leak.

Fluctuating Hot Water

Hot water that runs hot and cold can point to a worn diverter valve or a scaled heat exchanger.

Hard-to-Find Parts

When engineers struggle to source parts for your model, breakdowns take longer and cost more.

Rising Bills

Efficiency drops as a boiler ages. A new condensing boiler can make a clear difference to running costs.

 Trustindex verifies that the original source of the review is Google. Really happy with the work carried out by Alban Plumbing and Heating. They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house.
The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work.
I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

 Trustindex verifies that the original source of the review is Google. Asif has done a great job looking after our plumbing and heating for several years now. He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come.  His 5 star status is well deserved.

London Colney Boiler Installation: Your Questions

My boiler came with the house. Should I replace it now?

If it is well over a decade old, losing pressure or breaking down, it is worth planning a replacement before winter rather than waiting for it to fail.

Do I need permission to replace a boiler in my flat?

Often you need to tell the managing agent, especially if the flue position changes. We can provide the details they usually ask for.

Can you put the new boiler in the same place?

Usually, yes. Keeping the same position is quicker and keeps the flue route simple.

How much does a new boiler cost in London Colney?

It depends on the boiler, the property type and any system work needed. The survey and quote are free and the price is agreed before starting.

How long does a replacement take?

A like-for-like swap is usually completed in a day. System changes take longer, and we confirm timing with the quote.

Which areas do you cover?

We cover London Colney and the surrounding AL2 area, including Napsbury Park and Colney Street.
