Our Gas Safe experts are ready 24 hours a day to help with all heating and hot water problems:
We can repair every make and model of gas boiler. Our experts carry a stock of common replacement parts in their vans. When specific parts are needed, we have a huge network of trade suppliers to call on to source them quickly.
We install hundreds of new boilers every year, and are approved installers for the following brands. If replacing a broken boiler is more economical than repairs due to its age or condition, we can recommend a model for any property or budget. Our customers can also benefit from extended warranties when we fit these makes.
Aspect sent a plumber within 2 hours of taking the booking, as it was an emergency. Mahmoud was very friendly and knowledgeable. He fixed the noisy, leaking taps and restored hot water (boiler problem). Very pleased with the service.
Lucy, Clerkenwell, EC1
My boiler had completely stopped working. The gas engineer arrived on time. He was very polite and identified the problem quickly. He organised for Cadent to arrive and check the incoming gas supply, carrying out further boiler repairs. Very impressed!
Sophie, Knightsbridge, SW3
The gas engineer was so thorough and was seriously aware of safety and doing a proper job repairing my boiler. He was very polite and good at his job. Highly recommended.
Alex, Cheam, SM2
Outstanding service, the engineer who fixed our boiler was super nice, and he made a point of explaining what he was doing at each step.
Ana, Kilburn, NW6
Our gas engineer was a hero. He worked tirelessly to get our boiler working and heating back on after 4 days of no heating. Even going above and beyond to fix any unexpected issues. He was friendly, tidy, and ensured everything was working before leaving.
Holly, Kingston, KT2
We are lucky to have the gas engineer install the gravity hot pump for our boiler system. He provided a brilliant service, is very polite and knowledgeable in explaining every step. Would definitely recommend Aspect!
Miffy, Harrow, HA1
The gas engineer couldn't fit a bracket on the flue, as there was not enough room. He fitted some galvanised banding instead to keep it in place. He worked very hard to get a satisfactory outcome. I am pleased with the work. He was honest and hard working.

This video shows how non-invasive methods are used to detect hidden leaks on a central heating system.
Several techniques are usually used during a thorough investigation to pinpoint leaks. The approach we take is required by insurers when processing a “trace and access” or “escape of water” claim.
Once the leak is found, our Gas Safe experts can make repairs and estimate the reinstatement work needed to return the affected area to its original condition.
