I had a bit of a disaster with a radiator which gushed out water when I tried to fix it. Aspect sent out an engineer the same day to my address in London E14. The matter was fixed in 5 minutes and he also took the time to look at the other radiators and carry out general checks to check that everything was in order. In my experience, Aspect were great. When you call on the phone you get a person who is switched on and wanting to help, not a grunt or a simple "Yeh?" like you get with other companies. The engineer who came was polite and he explained everything that he did to remedy the problem. Though Aspect are not cheap, they are a a company I would use if the need arose again, as they resolved my matter quickly and professionally. I am delighted.
