Dear Mark,


This morning as advised I had a visit from Mike to look at our Boiler. Hence the reason I write this email to you.

I deeply suspect that my boiler was ‘behaving’ itself this  morning because it knew that the engineer was coming.  That said I was very much impressed by the standard of Mike’s work and attention. He took his time and along the way we chatted. I must say I probably know a fair bit about boilers too!!

He was friendly and professional and knew what he was doing and talked me through the different processes.

To be honest I was expecting another ‘cowboy’ who would do a poor job and charge high for it. Alas Mike was not this narrow generalization  or expectation of mine.


Yes your company/service has proved the first rule of reliability and professionalism. I am humbly impressed.  Well that is enough praise for you guy’s….I wouldn’t want  you guy’s to get too relaxed in basking from all this praise from meJ.


Also if you  do introduce a private customer contract I would very much be interested with this. So please can you keep me updated regarding this.


Kind Regards and much thanks




PS XXXXXXXX XXXX is my other contact email I can be reached on for updates.


PPS- I was that impressed that is why I write this email. Normally I wouldn’t.


PPPS- I hope I won’t have to call you guy’s out again in a hurry… …BUT if I do I know who I’d callJ.


Dear Mark

Thank you very much for your speedy advice and help to get John at such short notice to assess our Gloworm boiler. John is amazing and very helpful and knowledgable. We are so appreciative and happy to have our heating on after two weeks of misery over christmas. We will be recommending your services to our neighbours as honesty and professionalism needs to be recognised and valued.

John mentioned he would speak to you about our megaflow tank servicing so i am sure we will be talking to you again soon.

Kind Regards

Thanks Mark,

Payment has just been made by BACS.


System seems great – very happy with installation etc.


Once again thanks to Calum for an excellent job.



Hi Chris

Short note to say a big thank you - great web site and great service too!  Couldn't quite believe your guys came out so quickly.One very happy and satisfied family who had forgotten what a good shower was like! Made us realise the flow/pressure must have been poor for a long time then just got worse. The diagnosis took some getting to, then we finally got it sussed and found you.

We'll be back for next year annual boiler and Megaflo service - booking well in advance so you can fit us in.

Running a service business myself I love it when I come across another that seems to genuinely care about what they do......



Hi Mark


I just wanted to say a big thank you for the quality of service you provided for us recently.


After experiencing the standard of another qualified boiler engineer who failed to turn up as previously arranged, without explanation or even any contact. It was a relief to have a smart and knowledgeable boiler


engineer arrive promptly on time and confidently deal with the problem on our ageing boiler.


It is very reassuring to have your number in our telephone book for the next time we need a service or call out with our boiler.


Thanks again,


Steve Helkin

Genius!! You must get pretty tired of mugs like me asking about the same problem?!? Thanks a lot Mark.

Best, Charles

 Dear Mark,

You and your photos on your website are AMAZING and FANTASTIC.  Thank you so much,  I have been able to re-pressurize.

I have been and shall continue to spread the word about you, and will definitely be calling if I am in need of boiler services.

Wishing you the very best and wonderful rest of year.

Kind regards,


Hi Mark,

Calum has just been & gone- what a nice chap. Can you just pass on the message that we are really grateful that he came out at such short notice.

Thanks again,


Hi Mark,

thanks for getting back to me. I called Calum and he sorted it the same day as he was in the area.

Very happy with the service, I'll definitely recommend you guys.

Thanks again

Hi mark,

Thank you for your reply. I've been checking it and it's been fine overnight and today aswell. The pressure has dropped a little but only because I bled one radiator. I'll top it up later. Once again thank you so much for your response, it's great peace of mind now u have answered and knowing someone like u is there to give advice.

Kind regards


Dear Mr Ray,

Thank you for coming to look at our boiler ignition problem.  I am impressed with your service to correct it as it may have been one waiting to happen as you state.

When you have time I look forward to your quote for putting a filter on the boiler system.


Mr D. Cave

Mark you are a diamond,I have adjusted d 0 down to 18 and bingo all rads are warming up together and boiler is running fine  .I live in Hoddesdon Herts so if you come out this far you can do the next service will be in touch 

Many thanks


Dear Mark and Chris,

It was just pointed out to me that I sent this email to the wrong address last week.

I don't know if you'll remember my call last Saturday, you called me back on Sunday and very kindly coached me through resetting my boiler?

I just wanted to say how absolutely terrific you are. I haven't stopped telling people about you and how you have restored my faith in human nature.

Both day and economy 7 elements have been working perfectly since. I know that work will probably need to be done as they stopped working correctly for some reason. I am going to leave it for now as it's been a very stretching month financially but would never consider anyone else for the job.

You're just wonderful and I can't thank you enough.

Best wishes,

Julie Guirguis
