Prices you know before we arrive

Most firms will not tell you what a visit costs until the engineer is at your door. We publish ours. You pay a fixed amount for us to attend and spend up to the first hour on the problem. If more work or parts are needed, we explain why and agree the cost with you first.

How it works

  1. Call or send an enquiry

    Tell us the boiler make, any fault code and your postcode. We confirm the attendance price and the next available appointment.

  2. The engineer finds the cause

    Our engineer diagnoses the problem and explains what is wrong, what it will take to fix and what it will cost.

  3. You decide, then we fix it

    Nothing extra happens without your agreement. Many repairs are finished on the first visit. If a part has to be ordered, we tell you how long it will take.

Areas we cover

Our base is in Southsea, so Portsmouth and the surrounding PO postcodes are our home patch. We also cover Southampton and Guildford, and visit Reading on scheduled days.

Why choose R-Gas

Our own engineers. We employ our engineers directly instead of passing your job to a subcontractor. We know who is coming to your home and we stand behind their work.

Lots of breakdown experience. Our engineers repaired 908 boilers in the last 12 months, many of them for national insurance and home-assistance providers. That experience is now available to you directly.

Straight answers. If a repair is not worth it, we tell you. If a part has to be ordered, we tell you when it will arrive.

Landlords and letting agents

We handle repairs, servicing and gas safety records for landlords and agents around Portsmouth and Southampton, with one point of contact and clear reporting.

Common questions

How much do you charge?

Boiler and heating diagnostic visits are £144 including VAT. Plumbing attendance is £96 including VAT. Both include the engineer coming to you and up to the first hour. After that, we price any further work and parts and agree them with you before we carry on. See our prices page.

When can you come out?

We answer the phone 7am–8pm, 7 days a week. We give you the next available appointment when you call. Same-day visits are often possible, but we will always be straight with you about timing.

Are your engineers subcontractors?

No. Our engineers are directly employed by R-Gas Heating, so the person who comes to your home works for us and we take responsibility for the work.
