Oil and LPG boiler replacement for Paisley homes

Every property in Paisley is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.

If your home near Paisley is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Bungalows and detached houses near Paisley running on LPG can move to a heat pump, with the tank collected by the supplier.

Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.

  • Detached houses and bungalows with garden space for the unit
  • Owners tired of fuel deliveries and tank maintenance
  • Older oil boilers nearing the end of their life

What's included

  • Help arranging LPG tank collection with your supplier
  • Free survey with a detailed heat loss calculation for older construction
  • Outdoor unit, heat pump cylinder, controls and radiator changes
  • Network operator notification and electrical connection
  • Oil tank draining and removal or making safe, as set out in your quote

Owners across Renfrewshire and Inverclyde can have oil tank removal arranged alongside a heat pump installation in Paisley.

Grants and rules for heat pumps in Scotland

Scotland

In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Paisley home, apply and receive the written offer before the installation date is fixed.

There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.

The steps for replacing an oil or LPG boiler with a heat pump in Paisley

  1. Send your postcode and a few details, or use the guide price tool.
  2. A surveyor visits your Paisley 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 an oil or LPG boiler with a heat pump in Paisley: questions

Do I need new radiators for a heat pump in Paisley?

Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Paisley home gives a room-by-room list.

How long does installation take in Paisley?

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

What size heat pump does a Paisley 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 Paisley home.

What happens with a leased LPG tank?

Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.

Do I have to remove my oil tank?

Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
