Replacement of combi boiler

The plumber arrived 10 minutes early. The job was completed within the time estimate I was given. I’m delighted with the standard of the work done. The plumber tidied up beautifully once he’d finished.

Fitting a boiler

2021-12-01

My boiler packed up last week and within 5 days I had a new glow worm unit with a 10 year guarantee. From the time I contacted Evo to the time the final checks were made by the most efficient and polite engineer they were nothing but professional, knowledgable, courteous and hard working. I have used many tradesmen over the last 40 years and Evo are right up there!!!

Boiler servicing in London

Of course there is no convenient time for a boiler repair, but you could avoid costly repairs by having your boiler serviced regularly.

The ideal time to have your boiler serviced is in the spring/summer period when you should no longer require the heating on. As we are a heating company covering London where the weather is, to put it mildly, changeable, please don't hold us to that.

Servicing your boiler allows early identification of leaks and potential faults. Not only can regular, professional maintenance of your boiler save you money, it can also reduce the risk of danger and the potential problems associated with carbon monoxide.

What is involved in a boiler service?

  • An assessment of:
    • Boiler, controls and components
    • Vital parts (heat exchanger and ignition)
  • Checking for water leak signs on seals and washers
  • Inspection for corrosion around and under the boiler casing
  • Check boiler flue internal and external for corrosion or damage
  • Carry out a burner and pressure test to boiler
  • Gas tightness test may be included to test for gas leaks
  • Flue analyser test (at no extra cost)

The flue analyser test is to check the combustion and burner pressure of the boiler. Specialist test equipment is used to enable the engineer to measure the concentrations of the pollutants present and to adjust your burners for optimal combustion. This means that the correct amount of gas will go through your system and help to identify dangerous levels of carbon monoxide.

Gas boiler service

2025-07-01

Steve was brilliant. Not a massive job but he showed up as agreed and sorted out the issue quickly. Lovely personable, polite guy, have now put in my contact list should the need arise and I would have no hesitation recommending him to others in need of plumbing or heating services"

Gas boiler serviced and tap replaced.

2025-06-01

I had very low cold water coming through the upstairs bathrooms. EVO identified the problem quickly. An airlock blocking cold water passing through the pipes. A thorough check of the plumbing was undertaken and the airlock removed. A post repair check was undertaken including checking the cold water levels in the loft cold water tank. Everything is running smoothly. Thank you EVO.

Replace boiler for new boiler

2025-05-01

I was really pleased to get a quick reply to my search and the offer of a visit the next day. The engineer to confirm time of appointment. This didn't happen and no reply when I followed up. But I got up early and prepared space etc to make the work as easy as possible. Again just a waste of time. DREADFUL! It seems that this one of your companies bid quickly to give themselves the opportunity to consider whether they want the job, blocking off the options of others?
