Good service fitting new boiler
Customer Service
Quality
Value
My old boiler broke down during the recent very cold spell of weather on a Friday and I contacted AGW mid-morning. They provided good advice, a competitive quote and a commitment to install the following Monday. AGW turned up early Monday morning and fitted the boiler that day, with minimum fuss, no mess and good communication throughout, taking time to explain how to operate the new digital control panel. I have been using AGW to service my boiler for several years now and they are an excellent local company who respond promptly and gives you honest advice. I could have spent hundreds trying to patch up my old boiler, but the advice I was given was good

We have used Andy for our heating and plumbing needs for over 12 years and always find the quality of the service outstanding. Ben and Tim came to us this time, they installed and commissioned a new boiler and also replaced a built in shower. They were polite, efficient and very tidy and the work was completed in a single day, we had no mess to clear up afterwards. As usual, a five star service from AGW Gas and Heating.

Andy and the team at AGW replaced our decrepit floor-standing boiler with a new bespoke one from Worcester Bosch for our old town house. Professional from start to finish. Great communication and an eye for detail. I think we'll be getting them back for our new bathroom now we've seen how good they are.

From start to finish Andy and his team were excellent in quoting, delivering and installing to a high standard. We have used AGW Gas many times previously and always been very satisfied with the service offered, whether it is servicing the boiler, troubleshooting or replacing. On this occasion his team of two arrived promptly as scheduled at 8am, and had completed by mid-afternoon, leaving the area tidy, and the system fully programmed so I didn't have to worry about sorting this out. Everything was delivered to budget, and schedule. Excellent as always, thank you Andy and team.

After the initial phone call and diagnosis that a new boiler was needed, an early date (within a week) was agreed upon to supply and fit a new Boiler. The fitters arrived on time with all the necessary tools to complete the job. The job was completed in the allotted time with all areas left clean and tidy. The original quote given was what was invoiced.

Central Heating Boiler replacement

We have engaged AGW for all our plumbing and central heating needs for many years now. They are experts in their field and we have never had cause to complain. Not only do they work efficiently, but they also explain everything carefully, are unfailingly polite and never leave a mess, putting protective coverings down where necessary and removing all replaced parts and equipment. The current job was done within a few days of AGW diagnosing the problem during a routine boiler service. The replacement of our boiler took only a few hours. It was, as ever, a pleasure to do business with AGW.

Has a can do approach and is up to date with the latest developments in his field. One of his great strengths is an eye for designing installations. He is able to suggest ways of achieving the desired outcome that perhaps had not been considered. It’s always been a pleasure to deal with him, Tim and also now Ben.

I’d contacted a couple of local firms after my boiler are provider let me down following a boiler. A couple didn’t return my calls and another was busy for a few days. I had no hot water and heating so Andy kindly agreed to attend my property and check the boiler on the day I rang. Whilst the boiler was beyond repair he quoted me for a good quality boiler and some associated work within a day of attending which I was really impressed with. His team replaced the boiler the following week and everything was completed to a high standard. Excellent and honest response and I would highly recommend.

AGW have been servicing our boiler for years and when it finally came to the end of its natural life. They came to replace it. Not only did they replace our old boiler but ensured everything was up to date by adding legislative items to ensure safety and efficiency of the new boiler. Respectful of our living space, clean and tidy. Easy to book and providing a great service with trusted products and friendly engineers. Highly recommend AGW.

My boiler was blowing fuses and started failing during the coldest snap of the year on Monday 6th January. I changed the fuse a few times in the boiler spur, but something was clearly very wrong. I emailed AGW on Monday via their web contact page. I got a telephone call within 3 hours which I was super impressed with and a visit from Tim and Andy the same afternoon to look at a solution. They offered me a cheap fix which would have tided us over for a while, without being too expensive. I decided however that I'd like to have the boiler replaced as it was 15 years old. We also discussed the suitability of an air source heat pump, but the microbore pipework didn't lend itself well to such, so opted for an efficient gas boiler instead. Work was booked in for the Friday, however, Andy went the extra mile and came midweek to fit a new immersion element into our boiler to get us some hot water. The old immersion wasn't working at all and we had cold water AND a cold house until he replaced that. The new boiler was fitted as per being booked in on the Friday and there were three engineers on site all working throughout the day. They did a great job and were highly professional throughout, I couldn't ask for a nicer bunch of guys. A slight issue cropped up where the boiler errored on Saturday morning. Tim came within an hour and sorted it; the condensate pipe was blocked likely due to food build up in the kitchen sink drain, so my fault! Fixed in 5 mins! I'm a super happy customer.

In my hour of need, I called Andy for an estimate. He responded quickly and called within the same day. Later he sent me an e-mail with an estimate. He offered to fit a replacement within 48 hrs. Two days later at 8am both he and Ben arrived. At the same time, the delivery van arrived with the ordered boiler and parts required. Having not much room for two men to work he left me in Ben’s very capable hands. Ben worked tidily and efficiently to carry out the work completing and testing the work just before 5 o’clock the same day. I would thoroughly recommend AGW and his team to anyone. Having worked myself in the same industry I recognised the true professional way everything was done.

AGW carried out a complete refit and upgrade of our gas central heating system. They fitted a new boiler, cylinder and all new system controls and electronics replacing several radiators and tidying scruffy original new build pipework as well. It is all working well and we were even able to leave them to it for several days while we went away to avoid an unheated home in November. We returned to a beautifully warm, clean and tidy house almost as if they had not been there. Couldn't ask for better. Andy was really helpful and informative throughout.

I needed my boiler, thermostat, and a new bath pop-up plug fitted. Tim and Ben did an excellent job — my boiler now runs quietly, the house feels much warmer, and the thermostat is dependable. They were a pleasure to have around, and when they left, it was as if they hadn’t even been there. The work was highly professional, and I’m thrilled with the result.

Following a recent boiler upgrade, we now wanted to improve on both the look and efficiency of existing 30-year-old plus, radiators. We knew roughly the style we wanted so with Andy's help to make sure they were of the right size and specification for our system, we booked an installation date. Tim and Ben did the work to a very high standard and we are very satisfied with the outcome. Installation was carried out with minimum fuss and completed on the day arranged. Having also used them for two previous boiler upgrades in family properties, we can highly recommend the services of AGW Gas & Plumbing Services and have found them to be honest, diligent and competitively priced.

Old bathroom transformed into modern shower room
Customer Service
Quality

Andy and Tim are top-notch bathroom and kitchen renovators. This is the 6th big job (kitchens and bathrooms) they have done for me over the past 20 years. I always use them because of the high quality of the design, the recommendations about materials, the high standard of workmanship and finish, as well as the fact that they are so clean and tidy during the job, and they both are very friendly and pleasant personalities. For this job, despite always being busy, they fitted my job in due to my need to have a walk-in shower fitted prior to a hip replacement operation. They removed the old tiling, bath and flooring, and installed a full-length shower tray and screen, shower and controls, grab rails and fully shower boarded the room with new flooring, re-installing the vanity and toilet, leaving the shower room completely transformed from the original 12-year-old bathroom. I now have a fully functional, clean and modern shower room that fits in with the rest of the decor in my modern apartment. I am so happy with the final result. All of the work was completed on time and on budget, and no problems were encountered, if there were, they solved them. Andy and Tim work as a wonderful team, they are both really helpful, left my apartment clean and tidy at the end of each day's work, kept me updated about the work, what would happen the next day, removed all of the rubbish and contacted me after completion, to see how I was enjoying my new bathroom. 5 stars, brilliant.

Andy and Tim have done several jobs for us over the last 12 years, including fitting a new boiler. On this occasion we had been experiencing problems with our heating not switching off. A faulty part was identified and ordered, and a date made for replacement. In the meantime our hot water failed as a result of the same faulty part, so the appointment was brought forward and fixed quickly. Andy and Tim always keep appointments, carry out the agreed work, and leave the areas clean and tidy. We trust them to prioritise their workload so as to rank the importance of individual customer jobs.
