I spoke to my tenant at the property today who was very complimentary about your service in general and about your gas engineer in particular. She reported that he was very thorough with the check, very polite and put on shoe coverings before entering the property.

A. Fisher – Landlord

Extremely efficient, professional and courteous.The work was completed on the same day as I had reported there was a problem.

Mrs Harger

Just to say as always top quality service (both from your office and your colleague on site) and all sorted…..please do feed this back.

S. Mirza

John, Ginney and Mark are absolute amazing people. Always on hand to fix any challenges and prices are all clear & explained before hand. In the 10 years I have used them to do my Gas safety’s only 3 have come back needing additional works. Honest, trustworthy trades people.

Letting Store

I would like to say that Sebastian was excellent.

G. Daniels

Thanks as always, as efficient as ever! Thank you for your help in co-coordinating this job! Perfect and thanks for all your help this year

J K – Landlord

Great service as usual from the team at Baker Smith to replace our shower, cistern and some general plumbing work. Have never been disappointed over the last 15 years. John, Mark and colleagues have always provided good, practical advice as well as having a team who do excellent work.

Mark G, St Albans

Not only did they find the problem within 10 minutes they contacted me to say that they had sourced the part needed from the company and found out my shower was still under warranty. They gave me all details to contact this company. What a reliable, trustworthy service.

J R, Ground-force SOS Limited

They’re very efficient and always get back to me, they have good communication and do a good job!

S. Bone

The plumbers were so lovely and friendly which helps matters

L. Pearce

The Baker Smith plumber initially did a temporary repair (after my Emergency Cover provider plumber had failed). Baker Smith then went out of their way to source the necessary part & did the final repair very promptly-all a reasonable price. This firm is trustworthy, professional & reasonably priced. Highly recommended.

S. Mason

They took a pride in their work and it showed at every stage. When solutions were needed they provided them without causing any stress and the quote was honest and fair. I would always turn to them for future work and am happy to recommend them highly.

J. Robinson, St Albans

I had a visit at 4.40pm on the same day and it was fixed by 5pm! Polite, efficient, and high tech (sign off process). I was so impressed by their site, I passed their details around at work!

Tenant of Town & Country Lettings

The staff that we dealt with were professional, efficient, and outlined the costs involved clearly. On day one the boiler was removed and system flushed and on day two the new boiler was fitted and worked completely. All in all a great service from start to finish.

B, London Colney

Baker Smith were quick to identify the source of the leak and put a temporary fix in place whilst they ordered the correct part. Part was delivered and installed the next day and both we, the managing agent and the tenant were happy with the outcome.

S. O’Carroll

The team were incredibly helpful and patient answering all my emails and my phone calls, I was really impressed to not only receive a quote very quickly but also the offer of potential dates that were convenient for me to complete the job.

C S, Welwyn

Excellent service. Friendly, professional and polite.

J. Simpson

Fabulous work done fitting new pipe work for us – would recommend these guys to everyone! I’ve used them twice now and both times service has been fantastic. Polite, on time, trustworthy, and a good job done. I don’t recommend very often but you guys deserve to be shared around!!!

N M Stevenage

At very short notice, Mark & his team delivered an extremely friendly & efficient service. I will certainly use them again & would have no hesitation in recommending them to others.

Brosko Dragovic

Excellent work as always plus boiler report etc.

D. O’Halloran, St Albans

The toilet had been destroyed at our local scout hut at 9 o’clock at night. As that scout hut was needed by a toddler playgroup from 9 o’clock the following morning, you very kindly re-jigged your running order to be on site to repair things in time.

R. Oldfield

I can honestly say that in all instances when they have done work they have been a pleasure to deal with. From the start the professionalism and service ethic of the company was evident. Every contact has been pleasant and efficient, nothing has seemed to be a problem.

J. Robinson

Very happy, thanks! Both the engineers and the office staff are always very pleasant and helpful.

Lettings Consultant, Town & Country

The installer was excellent – very polite and a very good worker.

Marie Burke

Turned up promptly, fixed the problem quickly. Neat and tidy workmanship.

Minute Man Press

You did an absolutely brilliant job fitting our new water heater, your engineer was very neat, polite and I am very pleased with the service rendered by Baker Smith plumbers.

J E, St Albans

A quick inspection, a couple of twists and some fresh new installation to an external pipe, they reassured me that the boiler was actually safe to use. I am immensely pleased with the outcome.

M of SK Fitt, Photography

So pleased with the work done, very professional & neat. The outcome of installation was much better than I expected & location of the pump means a space saving in the cupboard…this is the second time I have used these guys & they are the best by a long shot.

They got in touch with me a day after I gave my referral and scheduled an appointment on the same day. He was friendly and professional, explained what he would check, asked when he needed to know any details and provided us with a gas safety certificate.

A K, Lemon Glass

John and Mark have established a well run and organised company so much so that I know of no other company where you ring them up and find that one of the partners is office based answering the phone, dealing with people’s queries and problems!

R. Wolff

Thanks Mark, You are the man and thanks for the new sink. No Sooner said, than done: so acts the man of worth. I have to say such friction-less invisibility to a client is something I have come to deeply respect and aim to emulate.

Just had Brian from Baker Smith Ltd install a new boiler at our property. The quote was provided quickly, they were on site in a few days and the work was completed quickly and professionally. We would highly recommend them!

Tally H, Luton

Thank you very much for the service – the plumber was very thorough and really looked for the cause of the problem.

E. Clark

From the excellent customer liaison, to the promptness with which we secured an appointment, to the professionalism of Tom who not only did the job but happily sorted out another plumbing problem I had forgotten to mention. I was impressed by the way every step in the process was handled.

T. Greenfield

My thanks to John and the team for fixing our boiler and such great service – and for the very reasonable charge too.

J Myers, St Albans

We are very happy with the installation, and thought Tom was very professional and did a great job.

T. Delves

The job was completed to a high standard and within good time, both the tenant and us were kept up to date with what was going on:time and dates that the job would be completed. We are thoroughly happy with the job and will continue to use Baker Smith.

C. Hornsey, St Albans

Booked via John Lewis home solutions for a boiler service. They were fantastic, excellent service, showed up when promised and were just great. Ironically we had a leak the next day and we used Baker Smith as they had been fantastic the previous day, a repeat sterling performance. Highly recommend.

A note to express our thanks to you both together with Ricky/George. We were most impressed by the efficiency and courtesy displayed during the installation, a great job – well done! Many thanks indeed.

Very efficient and prompt service despite my giving very short notice. Would use again.

Many thanks for the fantastic service fixing my w.c problem and fitting new taps, thanks to the brilliant engineer who carried out the work for us.

J. Robinson, St Albans

I have been using Baker Smith for over 10 years both in connection with the lettings department I run but also personally at my own home. They are by far the most professional firm of plumbers and heating engineers I have ever known!

R. Wolff

Being a management company we have to find reliable trustworthy contractors and would highly recommend them.

The Management Office

Dom arrived within time specified, left the area clean after he finished and explained what he had done, was patient enough to answer all of my questions. Thank you to the Baker Smith Team for your help and I will certainly recommend you to anywhere possible

C S, Welwyn

Very happy with the work carried out on both jobs. Arrived on time. I felt confident with the engineer’s ability. Price as discussed.

H. Fraser

I have used this company for the past 15 years I will continue to use them as they are very reliable and they always comeback if there’s a problem which usually there isn’t.

K. Wellesley

I have had new taps fitted by you. Tom is really amazing, can’t praise him enough for his politeness and professionalism. Please give him a raise! He deserves it.

The engineer seemed to know exactly how to replace the old taps and pipe work and just got on with the work.

The plumber from Baker Smith arrived on time, was polite and professional. The work was completed quickly and he cleared up the mess. He left all the spare parts together & explained I should keep them in case there was a problem in future. I was very happy.
