What Our South London Customers Say About Our Heating Service
Real reviews from homeowners across South London.
Our boiler broke down mid-January — no heat, no hot water. TopFix sent an engineer the same day. He diagnosed the fault quickly, had the part with him and fixed it within two hours. Brilliant service, very reasonable price.
Had cold radiators on one side of the house for months. TopFix came out, did a proper system balance and powerflush. The difference was immediate — whole house is heating evenly now. Really thorough work and they explained everything clearly.
Used TopFix for our annual boiler service. On time, professional and gave us useful advice about the system. Good to have a local company you can actually rely on. Already booked them for next year.
Frequently asked questions
For emergency call-outs in South London, we typically aim to have an engineer with you the same day. Heating failures in winter are always prioritised, and we're available around the clock for urgent situations.
This is usually caused by sludge or air in the system, a faulty pump or a need for system balancing. Our engineers can diagnose and fix these issues quickly, often in a single visit.
An annual boiler service is recommended to keep your system running safely and efficiently, maintain any manufacturer warranty and catch small issues before they become expensive repairs.
A powerflush is a deep clean of your central heating system that removes built-up sludge and scale. Signs you may need one include cold spots on radiators, a noisy boiler or the system taking a long time to heat up.
Yes, all heating and gas work is carried out by fully qualified, Gas Safe registered engineers. You can ask to see the engineer's Gas Safe ID card before any work begins — we're always happy to show it.
Expert Heating Engineers Serving South London
South London's got a lot of older housing stock — and if you've ever tried to get a heating engineer who actually knows what they're doing with a 1930s semi or a Victorian terrace, you'll know it's not always straightforward. We do a lot of work in exactly these kinds of properties. Sutton, Clapham, Wimbledon, Putney, Battersea, Kingston — that's our patch, and we know what the heating systems in these areas tend to look like.
Boiler stopped working, radiators cold on one side, need a full system put in — whatever's brought you here, we can sort it. Our engineers are Gas Safe registered, they carry most common parts in the van, and they won't start anything until you know what needs doing and what it'll cost.
One thing worth saying: we don't do vague quotes that suddenly go up once we're in. The price we give you before we start is the price you pay. That sounds like it should be standard — and it should be — but apparently it isn't always.
