5 Common Plumbing & Heating Problems in London Homes

A drip­ping tap might seem harm­less, but it wastes thou­sands of litres a year. A cold radi­a­tor could mean sludge block­ing your sys­tem. And a boil­er that keeps break­ing down is more than an incon­ve­nience – it is a safe­ty risk. In Lon­don, where many homes have age­ing pipework and com­bi boil­ers under pres­sure, know­ing when to call a pro­fes­sion­al plumber or heat­ing engi­neer is essen­tial. Here are five com­mon plumb­ing and heat­ing prob­lems and how MVA Home Improve­ment can solve them.

1. Dripping Taps & Leaking Pipes

A sin­gle drip­ping tap can waste over 5,000 litres of water annu­al­ly – and it usu­al­ly sig­nals a worn wash­ers or failed O‑ring. Leak­ing pipes, whether under the sink or behind a wall, cause damp, mould and struc­tur­al dam­age if ignored. Our Gas Safe reg­is­tered engi­neers trace the source of any leak, replace faulty com­po­nents and pres­sure test your sys­tem to ensure it is ful­ly sealed. We also pro­vide emer­gency call‑outs across Lon­don for burst pipes.

2. Low Water Pressure or Intermittent Flow

Low pres­sure when you run a show­er or fill a ket­tle is frus­trat­ing. It could be caused by a par­tial­ly closed stop tap, a build‑up of debris in pipework, or a fail­ing pres­sure reduc­ing valve. In old­er Lon­don flats, shared sup­ply lines can also be respon­si­ble. We diag­nose the root cause, clean aer­a­tors, replace faulty valves and, if nec­es­sary, rec­om­mend a mains pres­sure boost­er to restore a strong, con­sis­tent flow.

3. Cold Radiators & Noisy Central Heating

If your radi­a­tors are cold at the top but warm at the bot­tom, trapped air is the usu­al cul­prit – bleed­ing them often solves it. But if whole radi­a­tors stay cold, or you hear gur­gling, bang­ing or whistling nois­es, there may be sludge (mag­netite) build‑up or a fail­ing pump. We per­form pow­er flush­ing to clean your sys­tem, bal­ance radi­a­tor valves and replace any defec­tive pumps or motorised valves. The result is even, effi­cient heat­ing and low­er ener­gy bills.

4. Boiler Breakdowns & Inconsistent Hot Water

Your boil­er is the heart of your home. When it keeps los­ing pres­sure, switch­ing itself off, or pro­duc­ing only luke­warm water, you need a qual­i­fied expert. Com­mon caus­es include a leak­ing expan­sion ves­sel, a failed divert­er valve, or a bro­ken ther­mo­stat. Our NAPIT‑registered boil­er engi­neers car­ry out full diag­nos­tics, repair all major brands (Worces­ter Bosch, Vail­lant, Ide­al, Viess­mann) and pro­vide a fixed‑price quote before any work begins. We also install new A‑rated boil­ers with up to 12‑year war­ranties.

5. Blocked Drains & Slow Sinks

Slow drain­ing sinks, bad odours, or water pool­ing around a show­er tray are signs of a par­tial block­age. Over time, grease, soap scum and hair build up inside pipes. Chem­i­cal drain clean­ers can dam­age your pipes – we use pro­fes­sion­al drain rods and high‑pressure jet­ting to clear block­ages safe­ly. For per­sis­tent issues, we can car­ry out a CCTV drain sur­vey to iden­ti­fy col­lapsed pipes or root intru­sion, then pro­vide a per­ma­nent repair plan.
