Before you book: replacing a gas boiler with a heat pump in Maldon

In Maldon, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.

Installers in Maldon take out the old boiler and flue and seal the wall opening as part of the job. Many gas-heated homes in Maldon have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder.

Moving from mains gas to a heat pump means finding cylinder space, deciding what happens to the gas supply and comparing running costs on realistic assumptions.

  • Homes in England and Wales eligible for the Boiler Upgrade Scheme
  • Boilers that are old, unreliable or due for replacement
  • Households ready to give up gas entirely and drop the standing charge

What's included

  • Removal of the gas boiler, flue and any loft tanks
  • Free survey with heat loss calculation and cylinder siting
  • Commissioning, MCS certificate and grant application in England and Wales where eligible
  • Capping of the gas pipe at the boiler position where you are giving up gas
  • System flush and radiator upgrades where the design calls for them

If your Maldon home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.

Grants and rules for heat pumps in England

England

Homes in Maldon can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

What to budget for replacing a gas boiler with a heat pump in Maldon

The ranges below are typical installed prices for homes in Essex, including VAT. A survey sets the exact figure, because two similar-looking houses in Maldon can need quite different radiators and pipework.

The steps for replacing a gas boiler with a heat pump in Maldon

  1. Send your postcode and a few details, or use the guide price tool.
  2. A surveyor visits your Maldon home, measures every room and checks where the outdoor unit can go.
  3. You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
  4. Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
  5. The system is commissioned, set up with weather compensation and handed over with the paperwork.

Replacing a gas boiler with a heat pump in Maldon: questions

How long does installation take in Maldon?

Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Maldon home states the expected time.

How soon can you survey a home in Maldon?

Survey dates depend on how busy installers are in Essex. We offer the next available dates when you enquire and confirm them in writing.

How long does a heat pump survey take in Maldon?

A home survey in Maldon usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.

Do I need to replace the cylinder I already have?

Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.

What if my gas boiler is fairly new?

A newer boiler can still be replaced, but the timing is worth weighing. Some owners switch when the boiler needs a major repair; others prefer to plan the change for a convenient time. Across the UK, heat pump installation is zero-rated for VAT until 31 March 2027. A hybrid system, which keeps the boiler alongside a heat pump, is another option, though it is not eligible for the Boiler Upgrade Scheme in England and Wales.
