New Combi Boiler installation. Before purchase all of my questions were answered promptly. The installation has just finished and the guys were careful and helpful and kept me fully informed of progress. So what else is there to say to fill the number of characters required.

I requested quotations from several Suppliers for the installation of a new Worcester Bosch boiler. DHS (under the name Allworks) was the most thorough in inspecting the location of the boiler and providing advice as to the best options. The DHS quotation was the lowest of the three I requested and covered all the work necessary to instal the new boiler and remove the old one. A date was agreed for the work, and the two engineers arrived at the stated time of 08.30a.m and immediately commenced work to remove the old boiler. They took great care to lay down dust covers upstairs and downstairs by the front door. It was an awful day weather wise with heavy rain and windy, but the two engineers were cheerful and didn't complain about the weather. The job was completed by 3.30p.m. I was very impressed with their professionalism and enthusiasm. The installation involved the fitting of a condensation sink tank in the front garden - a job made more messy by the weather, but notwithstanding the conditions that part of the job was completed quickly with no fuss and no mess in the house. Both guys did a brilliant job of tidying and hoovering up afterwards - I was expecting to have to hoover around after they left but I didn't need to as the house was left so clean you wouldn't have know anyone had been in working. On completion the Engineer took time to explain the operation of the new boiler and the settings on the boiler and the digital thermostat. Fully recommend DHS to anyone.

I have a technical background and this is a very good firm. As always their work is done to a high standard, they do the quoted work very well as promised, on time and to the quoted budget. The staff are very knowledgeable, efficient, and helpful. Communication is excellent and so is their aftercare. I have used this firm for all my central heating work for many years and find them 100% reliable. They were also very good indeed at diagnosing and sorting out a complicated technical problem that we had with our old system a number of years ago.

Polite, friendly and efficient. Job done well and quickly. Highly recommend for your annual boiler service.
