What to know about replacing a gas boiler with a heat pump in Notting Hill
The question for a Notting Hill home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Semi-detached and terraced houses in Notting Hill often have an airing cupboard that can be reused for a heat pump cylinder. If your Notting Hill home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.
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.
- System or regular boiler homes with an existing airing cupboard
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
- 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
- Heat pump cylinder, outdoor unit and weather compensation controls
- Free survey with heat loss calculation and cylinder siting
- System flush and radiator upgrades where the design calls for them
- Capping of the gas pipe at the boiler position where you are giving up gas
Households across Greater London moving off gas can have a survey in Notting Hill that compares running costs on realistic assumptions.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Notting Hill quote.
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.
Guide prices for replacing a gas boiler with a heat pump in Notting Hill
The ranges below are typical installed prices for homes in Greater London, including VAT. A survey sets the exact figure, because two similar-looking houses in Notting Hill can need quite different radiators and pipework.

Short winter days in Notting Hill and what they mean
On the shortest day Notting Hill gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Replacing a gas boiler with a heat pump in Notting Hill: questions
How soon can you survey a home in Notting Hill?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
What size heat pump does a Notting Hill home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Notting Hill home.
Do you cover Kensington as well as Notting Hill?
Yes. We arrange surveys and installation in Kensington, which is about a mile south-east of Notting Hill, and across Greater London.
Is there a grant to replace a gas boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump that replaces a gas boiler, for eligible owners of existing homes. The MCS-certified installer applies to Ofgem and deducts the grant from your quote, and Ofgem contacts you to confirm. Scotland has separate Home Energy Scotland funding, and Northern Ireland has no dedicated homeowner grant at present.
Should I have my gas meter removed?
If gas is used for nothing else, removing the meter ends the gas standing charge, which is about £108 a year at the October to December 2026 price cap. If you still cook on gas or have a gas fire, you will need to keep the supply. Meter removal is arranged through your gas supplier, usually once the heat pump is running; the pipe at the boiler position is capped during the installation.
