Common problems we fix in Twyford
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Starting early leaves time for the survey, the design and any grant application instead of making a rushed decision when the heating stops.
If any of these sounds familiar, it’s worth a diagnosis:
- Ageing boilers that will need replacing
- Planning and permitted development questions
- Plans to switch to electric heating with a heat pump
If you live near Shawford station, the survey compares air-to-water and air-to-air for your home before anything is quoted.
Comparing quotes
- Why the equipment they’re quoting suits the job
- Who does the electrical work, and whether they can certify it
- If the figure could change on the day
Air source heat pumps for homes and businesses in Twyford
As an MCS certified installer, we fit air source heat pumps for homes in Twyford and the rest of Hampshire. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. If the problem is checking eligibility for a heat pump grant and an oil, LPG or gas boiler near the end of its life, we can help.
Space for an outdoor unit is rarely an issue near Twyford, so the design focuses on heat loss and radiators.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

How the visit works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Photos of the room and the outside of the property help us plan a visit to Twyford.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Before we arrive
- Dig out any previous service or F-Gas records
- Keep pets out of the rooms we are working in
- Let us know if the units are on a roof, a high wall or in a locked area
Getting a price
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

Let and managed properties
Whether it’s one property or many, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
FAQs for Twyford
Is planning permission needed for a heat pump in Twyford?
The answer turns on the property and where the outdoor unit would sit. The Twyford Conservation Area is close to the centre of Twyford. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Winchester City council, which is typically the planning authority for Twyford first.
Is Twyford within the area you cover?
Yes. Twyford is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
How much time does a heat pump install need?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The programme is planned to keep time without heating short and agreed before we start.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Will my radiators work with a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
What does an air-to-water heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales, and we confirm eligibility before you commit.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Homes in Twyford and heat pumps
Census 2021 figures found about 72% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Live in one of the older houses around Church of St Mary? Expect the survey to look closely at heat loss and at the building’s planning status.

What you can do yourself, and what needs us
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring 07833 053749.
