Boiler repair in Cambridge

The boiler faults Cambridge homes see most
In Cambridge's Victorian terraces, pipework has usually been reworked by several owners, so slow leaks, low pressure and sludgy radiators are typical. Suburban semis with loft tanks tend to lose pumps, valves and wiring centres. In newer homes, faults are more often sensors or pressure, and the boiler may still be under warranty. If yours is over 12 years old, a quote for a new one is worth getting at the same visit.
Victorian gault brick and red brick terraces: Pipework in these houses has usually been altered many times. Slow leaks, low pressure and sludge in older radiators are common.
Interwar and post-war semis in the northern and eastern suburbs: Regular boilers with loft tanks are still about, and valves, pumps and old wiring centres are common faults.
Recent developments on the city fringes: Faults in newer boilers are often pressure or sensor related, and some may still be under the manufacturer's warranty.

Boiler repair in Cambridge: questions
How much will a Cambridge boiler repair cost?
A diagnostic visit typically costs £80 to £120. Fitting a common part such as a pump, fan or valve is usually £150 to £350, and a main circuit board £250 to £450. You agree the price before the engineer goes ahead.
Can I get my new-build boiler fixed under warranty?
Check your paperwork first. Many manufacturers offer several years of cover if the boiler has been serviced every year. Contact the manufacturer before booking an independent engineer, as unauthorised work can affect the warranty.
Some radiators in my terrace are cold. What can I do?
If the top is cold, bleed the radiator and top up the pressure. If the bottom is cold, sludge is the likely cause, which is common in older Cambridge pipework, and a system clean with a magnetic filter usually fixes it.
What should Cambridge residents do if they smell gas?
Leave the home, keep away from switches and flames, and call the National Gas Emergency Service on 0800 111 999 at any hour. Once the supply has been made safe, you can book an engineer to repair the boiler.
