Having seen an advert for Domestic and General on line, I called AJay on the Tuesday to discuss what boiler would be suitable for us, Thursday two very pleasant and professional engineers arrived at 8.15 to install the boiler. Their work is second to none, very clean and tidy, no mess. The price quoted for the Worcester 30i was excellent. I would highly recommend Domestic and General.

Absolutely top class service. My boiler broke down again after being on a contract with British Gas for several years. We were left with no hot water or heating for almost a week. I contacted Domestic and General after seeing an online advert yesterday. They were very helpful and informative and after a late evening visit to check the right boiler model was ordered my new boiler was installed this morning by 2 pleasant and knowledgeable engineers. Arrived 8am and all completed by 11.45am. I thoroughly recommend this company. Thank you so much.
Excellent service. The installer carried out the work on time and with minimum fuss. Very polite and obliging workers. I thoroughly recommend this company.
