We offer boiler servicing in St Albans, Harpenden,
Radlett, Hemel Hempstead,
Hatfield, Welwyn Garden City and surrounding west Hertfordshire areas.
If you need a boiler repair please call us to make a
repair appointment. Actually we don't charge for a
boiler repair call out (first visit, if it is purely a
diagnosis visit), and we also treat
a boiler repair job as a matter of emergency.
For standard efficiency boilers (SE and non condensing
boilers) a service
is pretty straightforward. We charge £60 all inclusive for a service.
This type of boilers was
installed before 2005. The
efficiency of them are between 55% and 82%. As they are
simple and reliable, a significant amount of them are
still in operation.
We normally don't need to replace seals etc for
SE boilers while servicing, and their combustion
chambers are ready accessible.

For modern high efficiency boilers (we call this type of
boilers as with pre-mix burners, most being installed from 2005)
there are two types of boiler servicing.

annual basis which is generally a safety check and
some "top ups" and cleaning on hydraulic parts, the price is for £60. It comprises of a

manufacturer requirements in every a couple of years,

On a full strip-down service we need to clean the
pre-mixed burner, combustion chamber and main heat exchanger which
will normally need more labour and parts (burner
seals etc), so the price for this level of boiler
services is subject to the boiler model, typically
at £110 including seals and materials etc.

The full scope service fee for a
Worcester Greenstar i junior boiler, the most popular
boiler installed, is about £125 all inclusive. For an extreme example, a good full scope service for a Powermax boiler needs a couple of hundred

Boiler servicing checklist from Which?
What should and what shouldn't do in a boiler
As when you request a boiler service, your boiler is
still working, you might not know the difference before
and after a boiler service, and don't know what should a
boiler service do and what are not included. The rule is
very simple: boiler engineers should carry out boiler
service procedures by following manufacturer
What is the purpose of a boiler service?
To check and maintain its working status of a boiler. It
is always good to have a boiler service regularly, but a
boiler service is not just a cleaning procedure by using a hoover, it
involves mainly on combustion chamber - 1. heat exchanger,
main burner, pilot injector, and fan cleaning; 2.
checking burner pressure, gas rate etc, plus combustion
gas measurement for modern condensing boilers; 3.
Condensate path and trap check and clean; 4. Expansion
vessel's top up. The aim of a boiler service is to make
sure the boiler is working as it is supposed.
When should I have my boiler serviced?
In our opinion modern boilers don't need full strip down service
in first three years. So why do boiler manufacturers
require boiler annual services to valid their warranty?
If you read their service instructions you will know any
service within first three years might just be a
checking not to strip boiler down to clean and
re-adjustment. For obvious reasons boiler manufacturers
never said you don't need boiler services.
Will a boiler service prolong my boiler life
Partially yes and normally no. A boiler consists of many different parts. A
boiler life expectation is about 15 years. Ideally all
the parts on a boiler should work within first 15 years,
then in 16th year all parts failed. In practice this is
impossible, one or more parts on a boiler will be failed
before its 15th year, so you have a boiler breakdown. In
most cases, these breakdown parts, eg. fans, pumps and
PCBs, were not dealt with on
previous service. If
a boiler is beyond economical repair then it reaches its
end of life.
Will a boiler service prevent boiler future
It is always sad to get a call from a client to report
his or her boiler breakdown not long after we serviced it.
So will a boiler service prevent boiler future
Partially yes but normally no.
Boiler breakdowns are caused by failed parts which are affected
factors - boiler quality, intensive use, being properly
installed, maintained and protected etc. A boiler service is mainly for
safety check and combustion performance maintaining, not
involved in component replacements
for precaution purpose. Theoretically a boiler service
has little effect on preventing boiler breakdown.
most being replaced parts on boiler repairs are fans,
PCBs, pumps and
diverter valves(if it is a combi boiler),
but a boiler service dose very little for them which are
in fact not serviceable.
On other hand, a boiler service will definately have
good effects on boiler operation, eg, properly adjusted
combustion, clean flue way and condensation path, plus
re-pressured expansion vessel.
