Report
Having your gas boiler serviced annually, ensures that it runs efficiently and economically and above all else is that it is safe to do so.
This not only helps to keep your gas bills down, but also helps to reduce harmful co2 emissions which harm the atmosphere and lead to global warming and lastly if you are renting your property, then you will also need to show that your appliances have been serviced regularly.

When servicing a boiler we carry out the following:-

Clean burners and heat exchanger.
Check gas burner pressure.
Check Co2 and Co levels with a Combustion Analyser.
Check flue.
Visual check of appliance seals and casing.
Flame picture check.
Correct operation of safety devices.
Water pressure.
Check expansion vessel and pressure release valve.
Visual check for leaks.
Operational check.
Thankyou for visiting Maxgas, the No.1 supplier of Gas Safety Certificates, Installers of New Boilers, Boiler Servicing and Repair in London, Norfolk and Suffolk. If you are thinking of renting your property or you are a existing Landlord then we can help you to comply with your obligations and ensure that you stay fully legal and that your tenants are safe.
A new boiler is a big investment, get it right and you can have years of trouble free heating and a plentiful supply of hot water, get it wrong and it will cause no end of problems.

I've used Maxgas for both a boiler service and a repair of a minor boiler fault. On both occasions the work was carried out in a proffesional and considerate manner. I would not hesitate to recommend Maxgas. A 5* service all round. Service:Boiler repair

Amazing advice received having had our boiler break in minus temperatures - unfortunately we were way out of their catchment area but they kindly offered superb over the phone advice - very grateful indeed to have a now working boiler!

I used this company for a gas safety check and boiler inspection. I had arranged these services through OpenRent and emailed Maxgas to try and coordinate a time for the day that had been booked as I needed to let the tenants know a time for them to be at the property. I was only contacted a week later, 15 minutes before arrival. I was then sent an email about some screws which needed fitting and would be another 45 to install.

When I responded to the email (15 minutes after receipt), the serviceman had already left the property. He did not call me (though I'm in Canada, I still can receive calls on my UK number). I would avoid using this company. I now have to organise another callout and safety inspection.

I have used MaxGas for over 5 years now on my rental flat in Peckham and I trust Gary completely. He is completely professional, does a great and honest job and most importantly I can rely on him.

I needed a Gas Test on my rental property at short notice, they managed to squeeze me in and arrived when they said they would. Fast and very good value for money!

Very professional team. Arrived as scheduled and gave a very thorough service. In price comparisons their issuing of gas safety certificate and service was very good value. I shall use them again.
