    Heating & Plumbing Services

    One local, Gas Safe-registered team for everything from a leaking tap to a full boiler upgrade.

    Instant Plumbing & Heating covers domestic gas, heating and plumbing work across Chorley, Leyland, Preston, Wigan, Bolton and the surrounding Lancashire villages. From a same-day boiler repair and fixed-price combi swap to landlord gas safety certificates (CP12) and emergency leak response, the same Gas Safe engineer handles your job from first call to final commissioning.

    We're trained and approved by Viessmann, Glowworm and Intergas, and regularly fit Worcester Bosch, Ideal and Baxi — so the manufacturer's extended warranty is registered the day we leave. Every install includes a scale reducer on the mains and a smart thermostat as standard, with a manufacturer-approved system filter offered as an optional warranty-extending extra, itemised quotes fixed in writing and no day-of-work surprises.

    Boiler installation & replacement

    Fixed-price combi, system and heat-only boiler swaps with up to a 10-year manufacturer warranty.

    We size the boiler to your hot water demand, upgrade tired pipework where needed, fit a scale reducer and programmable thermostat as standard, then commission to benchmark so the warranty is registered before we leave. A manufacturer-approved system filter (which extends the warranty) is available as an optional extra. *10-year warranty applies to select premium installations, including specific Baxi, Viessmann models. Terms apply.*

    Boiler breakdown repairs

    Same-day response across Chorley, Leyland and Preston — most faults resolved on the first visit.

    Carrying genuine spares for Worcester, Vaillant, Ideal, Baxi and Glowworm means failed diverter valves, fans, pumps and pressure sensors can usually be swapped on the spot rather than scheduled for a return trip.

    Annual boiler servicing

    Pricing starts from £90 and varies depending on the boiler type.

    What can affect the price of your service? →

    Combustion analysis, gas-rate check, seal and flue inspection, condensate trap clean and a written service report sent the same day. We post a yearly reminder so you never miss a renewal date.

    Emergency plumbing

    Burst pipes, hidden leaks, failed stopcocks, blocked waste and overflowing cisterns.

    Isolation first, diagnosis second, repair third — with thermal imaging and acoustic leak detection used before any floorboards or tiles come up. Honest, itemised pricing and a 12-month workmanship guarantee on every visit.

    Landlord gas safety (CP12)

    Same-day CP12 certificates for landlords and letting agents across Lancashire.

    Tightness test, appliance check on every gas point, flue integrity inspection and digital certificate emailed direct to you and your tenant. Block-booking discounts available for portfolios of three or more properties.

    Radiator upgrades & balancing

    Like-for-like swaps, vertical designer radiators, heated towel rails and full system balancing.

    Cold spots, noisy pipes and uneven heat are usually a balancing or sludge problem, not a boiler problem. We use an approved chemical flush, rebalance flow rates room-by-room and fit TRVs so every radiator pulls its weight.

    Smart heating controls

    Nest, Hive, Tado and Honeywell Evohome supplied, fitted and configured.

    Wiring centre upgrades, dual-channel control for hot water cylinders, app pairing on your phone and a clear walk-through so the family can actually use the schedules — not just the holiday mode.

    Gas Safe engineer installing a new combi boiler in a Chorley home

    Boiler installation done properly the first time

    A modern A-rated boiler can cut a typical Lancashire household's gas bill by 20–30% — but only if it is correctly sized, properly commissioned and paired with the right controls. We start every quote with a heat-loss assessment of your home, factor in the number of bathrooms, mains pressure and flow rate, then recommend the boiler that genuinely fits — not the most expensive one on the shelf. Every install includes a mains scale reducer, new isolation valves and a 1-year workmanship guarantee on top of the manufacturer warranty. A manufacturer-approved system filter (which extends the warranty) is available as an optional extra.

    Most straight swaps are completed in a single day with dust sheets down, carpets protected and the old boiler taken away the same evening. Conversions from system to combi or back-boiler removals typically run 1–2 days, and we give you a written timeline before we start so the household knows exactly what to expect.

    Engineer diagnosing a boiler fault in a UK home

    Repairs that actually fix the cause

    Anyone can replace a part — the trick is finding out why it failed. Our diagnostic process pairs flue gas analysis, live-data fault reading and pressure-testing so we can tell the difference between a tired diverter valve, a sludged-up heat exchanger and a failing expansion vessel. That's why repeat callouts are rare and our average first-visit fix rate sits above 90%.

    You'll get a clear written quote before any chargeable parts are fitted, photos of the fault where it helps, and an honest second opinion if a replacement actually makes more financial sense than another repair on a 12-year-old appliance.

    Plumbing emergencies, contained quickly

    A burst pipe in a typical 3-bed semi can release over 400 litres of water an hour — long before you've finished mopping. The first job on every emergency call is isolation, the second is protecting your floors and ceilings, and only then do we move to the repair. We carry compression and push-fit fittings for copper, lead and plastic, plus a stock of common stopcocks, ball valves and immersion heaters so the fix usually happens on the same visit.

    Radiators & balancing

    Cold rooms upstairs and roasting hallways downstairs almost always come down to flow imbalance and sludge — not a tired boiler. An approved chemical flush, fresh inhibitor and proper TRV balancing usually transforms an older system overnight.

    Smart controls

    A correctly configured Nest, Hive or Tado typically saves another 8–12% on top of a new boiler by learning your routine and pre-heating only when it has to. We handle the wiring, the app pairing and the schedule setup so you get the savings, not the headache.
