A planned preventative maintenance programme brings structure to the servicing and inspection of your building's essential systems — replacing reactive problem-solving with scheduled visits, documented findings and clearer remedial planning. ComGas delivers co-ordinated PPM covering gas, heating, plumbing, electrical, HVAC and air-conditioning systems for commercial and industrial sites across Surrey and surrounding counties.
Scheduled care for buildings that cannot afford to fail
A maintenance programme built around your assets, your site and how it operates.
A maintenance programme works best when it is shaped around the actual equipment in a building — its age, condition, manufacturer guidance and how critical it is to daily operation. Before agreeing a schedule, we look at the assets present and confirm the scope and visit frequency so the programme reflects the property rather than a generic template.
ComGas can maintain gas, heating, plumbing, electrical, HVAC and air-conditioning systems within a single co-ordinated programme. The aim is to reduce avoidable failures, document asset condition over time and make remedial decisions easier to plan and budget for — with service and response arrangements confirmed as part of the agreed contract rather than assumed.
ComGas Services UK Ltd Planned preventative maintenance from Farnham, Surrey.
Systems we maintain
One maintenance partner across your core building services.
Choose a focused servicing agreement for a single discipline or bring multiple systems into one co-ordinated planned maintenance programme.
Gas, Heating & Hot Water
Scheduled servicing of commercial boilers, heating plant, gas systems and hot water equipment as part of a planned programme.
We agree the scope with you first — which assets are included, what visit frequencies are appropriate, how findings will be reported and how access is managed around your operations. Visits are then planned to fit around occupancy, trading hours or term dates, and findings are documented after each attendance.
Where additional maintenance or remedial work is identified during a visit, the priority is explained and any further work is separately discussed and quoted before it is authorised. Nothing outside the agreed scope is assumed to be included in the programme.
Scope and asset list agreed before the programme begins
Visit frequencies matched to asset type and condition
Access arranged around your operational timetable
Documented findings and condition notes after each visit
Remedial recommendations with clear priority assessment
Multi-discipline co-ordination within one programme

Matt from ComGas Services UK Ltd was very professional, polite, friendly and quick installing a new shower in my bath (and at a better height for me) and a much easier press-in plug for my sink! He left the place spotless. This is the kind of service and installation people dream about - a 5 star service (see photos).

I have used Comgas twice and both times have been very happy with the service. Very friendly and honest. The most recent time, the job turned out to be a lot bigger than they initially thought but it was no issue and Paul stayed the extra time to make sure the job was done properly! He was really tidy, took a lot of care with the work that was done and took the time to explain what he was doing and why. Pleased to have found a reliable heating company!

I had an issue with my boiler and Matt came out to have a look the same day and managed to fix it. Great, professional service. Highly recommend.

Fantastic experience from the chaps at ComGas! Special thanks to Matt who removed an old boiler and replaced with a new energy efficient to satisfy the demands of a five bed house with a few bathrooms/baths and showers. The ComGas admin team and Lee were fantastic too on the booking and administration side of things!

Here at St Joseph's we have worked with Comgas for a number of years. They have completed big projects and undertake regular maintenance for our school. They price fairly, and their work is completed to a very high standard. All the engineers carry a DBS which makes life so much easier when trying to book an engineer visit.
On the rare occasion that we have an emergency I can trust that Lee will get one of his engineers to respond quickly and efficiently.
Nothing is too much trouble and no job is too small.

PPM FAQs
Planned preventative maintenance questions
Common questions about ComGas planned maintenance programmes and how they are structured.
A planned preventative maintenance programme is scoped to the specific assets, buildings and requirements involved. It can cover gas, heating, plumbing, electrical, HVAC and air-conditioning systems within a single co-ordinated programme, with visit frequencies, scope and reporting format all agreed upfront.
How is PPM different from reactive maintenance?
Planned preventative maintenance involves scheduled inspections and servicing carried out in advance of failures, rather than responding only when something has gone wrong. The aim is to identify deterioration early, support safe operation and make remedial decisions easier to plan and budget for.
Can one contract cover multiple buildings or sites?
Yes. We can discuss asset registers, access arrangements, visit scheduling and reporting across a portfolio of buildings, then agree a structure that works for the operational requirements of all sites involved.
Does a PPM contract include emergency callout cover?
Callout and priority-response options can be discussed when the contract is being scoped. We do not publish standard response times, and any response arrangements are confirmed as part of the agreed contract terms — they are not assumed to be included as a default.
How is access managed for occupied or operational buildings?
Access requirements, working hours and any specific room or area constraints are discussed and confirmed before the first visit is planned. We schedule maintenance visits around the building's operational timetable where this has been agreed as part of the contract scope.
Tell us about your buildings and we'll suggest a suitable PPM approach.
Share what systems need maintaining, how many sites are involved and any particular compliance or access requirements. The team can arrange a conversation to discuss scope before any formal proposal is prepared.
