Your contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group, and the installation is carried out by installers we appoint and manage under that contract. Where you are eligible, the MCS-certified installer named in your quote applies for the Boiler Upgrade Scheme grant in England and Wales and deducts it from your price. In Scotland we work alongside your Home Energy Scotland application, and in Northern Ireland we explain what funding, if any, is currently available.
For older properties in South Glamorgan, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Installers working in South Glamorgan plan the order of work so heating and hot water are off for as short a time as practical. Many homes in South Glamorgan have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
Who it suits
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme

Grants and rules for heat pumps in Wales
Homes in South Glamorgan can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Air source heat pump installation questions
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
