Washington: your questions answered
Does the Boiler Upgrade Scheme cover homes in Washington?
Yes, the scheme covers homes in England, including Washington, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.
Will a heat pump in Washington need planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Washington is in the Washington Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with Horsham council, which is normally the planning authority for Washington.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
What warranty do I get?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays and any changes are in the quote.
About our air source heat pumps in Washington
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. If the problem is finding a place for the outdoor unit and replacing a combi boiler with a heat pump, we can help.
Homes around Washington usually have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

What else we do in Washington
Homes in Washington and heat pumps
The 2021 Census found about 84% of households in detached or semi-detached houses. Houses typically have space for an outdoor unit and a hot water cylinder.
Live in one of the older houses around The Parish Church of St Mary? Expect the survey to look closely at heat loss and at the building’s planning status. Parham House, roughly 3.9 miles west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.
Washington is about 6 miles north of Worthing, in West Sussex. From the centre of Washington to the outskirts, we cover air source heat pumps, from small jobs to large ones. Count every place we list in West Sussex and you reach 371, with Washington on the list. You can also see our page for Worthing, about 6 miles away.
Not far from Washington, a recent job of ours was on School Hill, Storrington (RH20), about 2 miles north-west: installing two LG wall-mounted units in the waiting room and the main consulting room.
London Road, The Street and Chanctonbury Close and the roads off them are all inside our area. We cover every part of RH20 for air source heat pumps and the streets around it. Places around Washington that are also on our list: Rock (1 mile north), Sullington (1 mile west), Heath Common (2 miles north-west), Storrington (2 miles north-west) and Warminghurst (2 miles north). Further out, we also cover Horsham (12 miles north), Worthing (6 miles south), Bognor Regis (15 miles south-west) and Haywards Heath (15 miles north-east).
Landmarks near Washington
Locally, jobs take us to houses, flats and workplaces close to Rydon Community College, Windlesham House School and The Frankland Arms Public House, among other places. Nearby you will also find The Storrington And District Museum (2 miles north-west). Open spaces near Washington include Chanctonbury Hill.
Different systems, different jobs
Hot water cylinders
Existing cylinders may not be suitable for a heat pump, and we explain whether yours can stay.
Radiators and underfloor heating
If radiators need upsizing, the quote lists them, so you know the full scope.
Rented and managed buildings
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
We also work for facilities teams in offices, schools and public buildings in Washington and across West Sussex. Work can be phased by floor, zone or building to keep disruption down.
Keeping the system healthy
A little care keeps the system in better shape. Our advice:
- Leave indoor units unobstructed
- Keep to regular servicing
- Keep the MCS certificate with the manufacturer’s paperwork
Once commissioned, we register the installation with MCS and give you the certificate. File it with the warranty documents for future reference.
Have the system serviced regularly. Your manufacturer’s warranty terms may say something about servicing.
What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it 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. If a lane or gateway near Washington is tight for a van, let us know and we will plan for it.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- 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.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Tell us about parking and loading
- Find the manual or the paperwork for the system, if you have it
Getting a price
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
