/ What the gas safety check covers
Under the Gas Safety (Installation and Use) Regulations 1998, landlords must have every gas appliance and flue they provide checked by a Gas Safe registered engineer every 12 months, give tenants a copy of the record within 28 days (or before they move in), and keep records for two years. Councils and letting agents will ask for it, and insurers expect it.
We check every appliance and flue in the property, carry out a tightness test on the pipework and issue the CP12 on the day. If anything fails, we tell you what's wrong and what it will cost to put right, and we can usually do the repair on the same visit so the certificate isn't delayed.
We work with tenants directly to arrange access if you'd like us to, and we'll email you before the certificate expires so you're never caught out at renewal.

/ Gas safety certificate cost in Winchester
The price of a CP12 depends on how many gas appliances are in the property — a flat with a combi boiler and hob is the simplest case. It's a fixed price, quoted when you book, and it's lower when combined with an annual boiler service on the same visit, which is what most landlords do. Any repairs needed to pass are quoted separately.
/ Covering SO21, SO22 and SO23 — the Cathedral, the High Street, Weeke, Badger Farm and Kings Worthy
Winchester's centre is full of period and listed buildings where flue positions, pipe routes and boiler locations need thought and sometimes consent — we're used to working with those constraints. Out at Weeke, Stanmore and Badger Farm the estates are more conventional, and Barton Farm brings a lot of new-build boilers into their first service cycle.
We cover the whole of Winchester (SO21, SO22 and SO23) — from the Cathedral, the High Street, Weeke, Badger Farm and Kings Worthy — and the surrounding areas including Kings Worthy, Alresford, Twyford, Otterbourne, Colden Common, Sutton Scotney, Bishops Waltham and Micheldever. Typical housing here is listed and period properties in the centre, post-war estates at Weeke and Stanmore, and new housing at Barton Farm, and our engineers know the boiler types, flue positions and system layouts that go with it.
We're based in Woking, Surrey, roughly 45 minutes from Winchester in typical traffic — a normal working day for us, not a special trip.
Same-day appointments are available for most of Winchester, and every job — a service, a repair or a full installation — comes with a fixed price agreed before we start and a written record when we're done.

/ Questions we get asked
Straight answers. If yours isn't here, call — it's quicker than a form.
How often is a landlord gas safety certificate needed?
Every 12 months. You can have the check done up to two months before the expiry date without losing time — the new certificate runs from the old expiry.
What does a CP12 cost?
It depends on the number of appliances. Request a quote and we'll give you a fixed price — and a lower price for combining it with a boiler service on the same visit.
What happens if an appliance fails?
We report the defect on the certificate and quote the repair. If it's immediately dangerous we'll disconnect it and label it, which is what the regulations require; we can usually fix it the same day.
Can you liaise with my tenants?
Yes. Give us the tenant's contact details and we'll arrange access and send you the certificate when it's done.
Do you offer annual reminders?
Yes — we email you before expiry and can book the renewal in advance.
Ready when you are.
