The local picture

Homes and plumbing in Forest Hill

Forest Hill sits on a properly steep hill, and that affects the plumbing more than most people realise. Big Victorian and Edwardian houses climb the slope, many split into flats. The drop from a loft tank to a top-floor bathroom is often too small to give good pressure by itself, so pumps and pressurised systems are the norm here, not an extra. Gravity drains on sloping plots also behave differently from those on level ground, and the original falls were not always set correctly.

How we can help

Plumbing and heating services in Forest Hill

  • Emergency Plumbing

    For burst pipes, serious leaks or a house with no water. The phone is answered at any hour and an engineer is sent out.

  • Boiler Repair

    Heating off, hot water gone or a fault code on the display. We find the cause, then fix it.

  • Boiler Service

    A yearly check to keep your boiler safe, running efficiently and covered by its warranty.

  • Boiler Installation

    Your new boiler, matched to the size of the home, installed well, at a price agreed up front.

  • Boiler Replacement

    A new boiler when the old one is finished, and an honest view on whether it really is.

  • Drain Unblocking

    Blocked sinks, toilets and outside drains cleared with the right kit instead of bottled chemicals.

  • Leak Detection

    Acoustic and thermal equipment to trace hidden leaks before any floor is lifted.

  • Bathroom Installation

    Anything from swapping one fitting to stripping out and refitting the whole room, priced before work starts.

  • Toilet Installation

    Fitting a new toilet, replacing an old one, or putting a WC somewhere it has never been.

  • General Plumbing

    Radiators, pipework, taps and toilets: the small jobs that keep getting put off.

  • Commercial Plumbing

    Plumbing for offices, restaurants, shops and blocks of flats, timed to fit the hours you open.

  • Gas Safety Certificates

    Your landlord gas safety certificate, checked and issued by a Gas Safe registered engineer and emailed over the same day.

  • CCTV Drain Surveys

    We send a camera into the drain to see the real fault, instead of guessing from the symptoms you notice at the surface.

  • Drain Repairs

    For drains that are broken, not merely blocked. We repair them by excavation or, if the run allows, with no digging at all.

  • Wet Rooms & Walk-In Showers

    Full wet rooms and level-access showers. The tanking and falls underneath decide if it will leak within five years or never leak at all.

  • Air Conditioning Repair

    Stopped cooling, leaking indoors or tripping the breaker? We track down the fault before quoting for anything.

  • Air Conditioning Maintenance

    A yearly visit to keep your system cooling efficiently and to catch a refrigerant leak before it turns into a breakdown.

  • Air Conditioning Installation

    Single and multi-split air conditioning, correctly sized and positioned, and installed by F-Gas registered engineers.

  • Air Conditioning Replacement

    Worn-out or failing systems replaced, including older units whose refrigerant is no longer available for top-ups.

  • Blocked Toilet

    A toilet that will not flush away, or one that keeps blocking. Cleared, with the cause explained.

  • Shower Installation

    Mixer, thermostatic and digital showers fitted — matched to the water system you actually have.

  • Shower Repair

    Weak flow, wandering temperature, no hot water or a leak — diagnosed and repaired, usually without a new shower.

  • Bath Installation

    One bath out, another one in — or the bath out and a shower in its place.

  • Tap Repair and Replacement

    Dripping, stiff and leaking taps repaired, and tired ones swapped for new.

  • Lead Pipe Replacement

    Old lead supply pipes replaced with new, from the boundary into the house.

  • Pipe Repair

    Burst, split, frozen and corroded pipework repaired — or replaced where patching it would be pointless.

  • Low Water Pressure

    Weak taps and showers diagnosed by testing, not by swapping parts and hoping.

  • Central Heating Installation

    The whole system — boiler, pipework, radiators and controls — rather than a new boiler on its own.

  • Surface Water Drainage

    Rainwater with nowhere to go — standing water on patios, paths and gardens, given somewhere to drain.

  • Gutter Repair

    Blocked, leaking, sagging and overflowing gutters cleared and repaired, along with the downpipes below them.

  • Leaking Ceiling

    Water dripping or pouring through a ceiling. What to do first, then the source found and stopped — in your home or the flat above.

  • Toilet Repair

    Toilets that will not flush, keep running, fill slowly or leak onto the floor. Usually one worn part, replaced without needing a new toilet.

  • Leak Repair

    Leaks you can see — dripping joints, weeping valves, perished hoses, overflows running outside — isolated, repaired and checked properly afterwards.

  • Electrical Repairs

    Tripping circuits, dead sockets, faulty lighting and extractor fans, traced and fixed with the price agreed first.

  • Emergency Electrician

    Power loss, trips that will not reset, burning smells and water in the electrics. We take calls around the clock.

  • EICR Certificates

    Electrical Installation Condition Reports for landlords, homeowners and buyers, with any remedial work priced separately.

  • Fuse Box Replacement

    Old fuse boxes swapped for modern consumer units with RCD protection, tested, certified and notified for you.

    Full and partial rewires for houses and flats, planned around you and the other trades, then tested and certified.

  • EV Charger Installation

    Home charge points surveyed, fitted, notified and certified, with any supply upgrades priced up front.

  • Commercial Washroom Refurbishment

    Staff and customer toilets, washrooms and changing rooms stripped out and refitted, planned around your trading hours.

  • TMV Servicing & Testing

    Thermostatic mixing valves tested, cleaned and reset, with a record for every valve, for schools, nurseries, care and business premises.
