Hear from our customers
Couldn’t recommend AHS Plumbing and Heating any more highly. From start to finish, the service was exceptional. Scott, Nathan, Steve, and Ethan were professional, courteous, and clearly take great pride in their work. The quality of their workmanship was outstanding, and their pricing was more than fair. They truly went above and beyond to ensure everything was done to the highest standard. I only wish I had known about them sooner—I wouldn’t have delayed the job for as long as I did. A genuinely brilliant team. Thank you again!
My family have used AHS for all our boiler care, plumbing and installations for over 30 years – I would not go anywhere else! They are a fantastic family run business, really helpful, professional, reliable, conscientious and friendly – could not be bettered. A great team of very knowledgeable engineers who take time to explain everything. I would thoroughly recommend them.
AHS have been servicing my boiler for many years now and they provide an amazing service. Their engineers and customer service is 1st class and they will always make sure everything is in order from start to finish.
I’ve had 2 replacement boilers from them over the years at 2 houses and with regular servicing from them I’ve had no problems at all.
I’ve also used them for landlord gas safety and annual inspections with the same professional quality service.
AHS have serviced and maintained my boilers for over 30 years. Their engineers are always prompt, polite and informative, explaining what needs attention, if anything. If I had any breakdowns during the winter months they were quick in their response and have always fixed the problem first time
Office staff are accommodating and always return my calls if busy
Prices are extremely competitive and fair in my opinion for the quality of service
Highly recommended *****
I’ve been using AHS for a few years now and they’re such a friendly and professional team. Booking a boiler service is always quick and easy, and when my boiler needed an urgent repair, they came out straight away and got it sorted that day. They’re reliable and so knowledgeable, I would highly recommend them to anyone!
