I had a Gas inspection few days ago to check my boiler as I didn’t have hot water as it keeps going hot and cold for about a year. I had carbon oxide in my back bedroom now it disappeared. I’ve got on... See more

I am here in tears. A priority appointment was made for me because I am a Elderly disabled person with no hot water or heating. I have been waiting for an heating engineer for 9 hours now. They should have been here 12.30pm.. now Smith and Byford wants to give me an appointment for 26th March. It's the 12th of March today. I am in so much pain because of my sickness.

The gentleman arrived explained who he was & what he was here to do. He was polite friendly & a chirpy chap. He went about my gas safety certificate test in a methodical neat and tidy way explaining what he needed to do & asking permission at applicable times. He was extremely pleasant & i cant recommend him enough.

AI 20 minute wait to speak to an agent then when phone was picked up nobody answered, just voices and laughing in the background.

I contacted Miriam at customer care call centre and explained my problem booking an appointment. She was extremely helpful and told me she would ring me Monday to try to sort something out. To my amazement she rang me first thing Monday morning and sorted my appointment for me. Exceptional service from Miriam more staff like this please. Thanks Miriam *****

I had a new boiler fitted on the 6th of February 2026 I’ve had nothing but problems since. I had to have them out the next day as the newly fitted boiler shut itself off for safety reasons apparently because of air in the system to cut a very long story short 3 visits leaking radiators, flooded floor, ruined flooring, flooded neighbours garden I have woken up this morning with exactly the same problem too much air in the system so boiler has shut itself down for safety reasons! Too be fair the lads that have been to try and fix the issue have been lovely however there is clearly a problem with the insulation as this problem would not keep happening. Really, really had enough.

This awful company left me for 2 weeks over the Xmas period with no heating as my boiler was leaking it’s the 20th February and it’s packed up again as it’s leaking again.. the service is awful and there engineers need to get out of the cafe in cheam village and actually do some work.. find it very very amusing when you leave a negative review on there website it won’t post it.. you couldn’t make this up..

Reply from Smith & Byford
Awful service, no-one answers the phone on hold for at least 20 minutes normally longer every time you call. No show for appointments, do not want to fix a problem. Pressure keeps dropping on new boiler, wish I had refused a new boiler now. No heating or hot water again, no idea when anyone is coming out as they can't even give an am or pm indication.

Reply from Smith & Byford
This firm is a joke I have been waiting in doors all day for a appointment that they gave me and said that they couldn’t give me a afternoon or day appointment for them to phone me at 4,45 pm to say a engineer will not be able to come out today 16/02/2026 I am self employed and have lost a days work and no one is accountable They say the will contact me for another appointment 🤡Swale are no better but they do eventually turn up . I couldn’t give no stars

Absolutely the worst company I've had to deal with. Ongoing heating problem that their engineers have been out to at least 4-5 times. Incompetent, no parts, dont turn up for appointments which I lose work for. So far, they've cost me around £400 in lost wages waiting for them to turn up. Still not fixed.
Emails of complaint sent which they don't even have the courtesy to reply to. They can't even give you a time or ask engineer to call when they're half hour away. Until recently, they didn't even have a call back system, meaning I've wasted hours on the phone trying to get through.
Steer clear if you have a choice.
I wouldn't even merit them with 1 star!

As per your reply,
I have already written to you several times with details of my complaint, why don't you look up on your system if you want to know the details or refer to RHP the housing partnership I also complained to?
I'm not doing your job for you or wasting any more time here.
As for reaching out through this platform and not getting a reply, you only posted this 3 hours ago! At least I move quicker than your company!
You have your reply.

I have to say that I moved from another service company years ago and I have never regretted it.
I had a problem with my shower so on ringing to customer service I was met with a lady with a charming attitude to which I explained the problem, she then arranged a time that was convenient to me. Very efficient and professional.
My engineer Simon turned up as arranged on time and quickly diagnosed the problem, he then explained what parts I needed to obtain.
A new appointment was agreed with the office.
Simon has just repaired the shower and has just left. Job done. Simon was respectful to my house and worked in a very clean way.
I have had to use Smith and Byford many times over the years and I can honestly say that they have never let me down and would thoroughly recommend them.
Many thanks
