I needed a new hob and was limited by size. I called 4 companies and they only wanted to refit the kitchen. Gas Mark1 were excellent from start to finish. They told me exactly what they would do to resolve my needs and the work which was completed yesterday was excellent. The electrician/gas specialist and fitter were top guys.
I paid them and they well deserved the business. My sincere thanks!!

Recently had a vaillant combi boiler fitted by Gas Mark 1. Couldn't fault them on anything. From first getting a quote (which was extremely reasonable) to installation all concerned were very professional and friendly. Wouldn't hesitate in using them again and thoroughly recommend.

Too busy to follow up on enquiries. Had 2 appointments in person, 1 home visit for measurements and despite various follow up calls no interest in providing any sort of customer service or completing a sale in a timely fashion. On the phone heard the owner comment he has 'messed me around' before passing the phone on to another member of staff.
Appreciate the difficult circumstances during COVID but if you are able to do a home visit and have a customer visit then have the decency to follow up. If you're too busy for the custom don't waste people's time. Similar stories from others - clearly the

GETTING WORSE!
I have been using them for years but since 2018 service and engineers and service seems to be declining.
I have started to get bad and bogus quotes for work and parts that DO NOT need replacing. Seems to be expensive and rushed lately,
so much so I have decided not to use them moving forward for the properties I own.
I asked them to proceed with some work over 1 month ago...turns out they did nothing and now come up with some bogus excuse for the delay.
In addition to this the quote seemed lazy...
My tenants Said "I have a problem with some radiators not getting warm."
