How much does a new boiler cost in the Cotswolds?

What local firms charge for a new gas boiler

Local published prices for a simple combi swap start at about £1,495 plus VAT. We found three firms near the Cotswolds that publish boiler prices on their own websites. Most local firms do not publish a price. They quote after a survey.

A "from" price is the lowest price. It usually assumes a like-for-like swap in the same place, with no pipe or flue changes. Check if the price includes VAT.

Prices that each firm publishes on its own website, checked on 15 October 2026. The pages give no price date. These are starting prices, not quotes for your home.

National prices for gas and oil boilers

National fixed-price firms and cost surveys give a similar range. These are national figures, not Cotswold quotes. Use them only to see if a quote is in a normal range.

What makes a boiler cost more in the Cotswolds

A change of boiler type adds most to the cost. A regular boiler to combi change removes tanks and changes pipes. The Gloucester firm above prices it well above a straight swap.

Moving the boiler adds cost, because the gas pipe, flue and condensate pipe must move.

Oil and LPG boilers often cost more than mains gas boilers. Off-grid homes are common in the Cotswolds. An oil boiler may also need work on the oil line or tank.

Flues in old stone houses can be harder. A long or vertical flue, or a flue that needs consent on a listed building, adds cost.

A new boiler needs a carbon monoxide alarm in the room, and often a filter and system flush. Ask if these are in the price.

How to compare boiler quotes

Prices vary; get at least three written quotes. Give each firm the same facts: the current boiler, the number of bathrooms and where you want the new boiler.

• Ask if the price includes VAT.
• Ask which boiler make and model the price is for, and the warranty length.
• Ask if the flue, controls, filter and flush are included.
• Check the engineer on the Gas Safe Register, or OFTEC for oil.
• Ask for the Building Regulations certificate when the job is done.
